[0008] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. However, such descriptions should not be interpreted in a limiting sense, and do not limit the subject matter described in the claims. Furthermore, various changes, substitutions, and modifications can be made without departing from the spirit and scope of the present disclosure. Furthermore, different embodiments can be combined as appropriate.

[0009] [Incineration system 100 in the first embodiment] First, an incineration system 100 in the first embodiment will be described. Figures 1 to 6 are diagrams illustrating an example of the configuration of the incineration system 100 in the first embodiment. Note that the arrangement positions, lengths, and numbers of pipes shown below are examples and are not limited to these.

[0010] As shown in FIG. 1, the incineration system 100 includes, for example, an incinerator 1, a dust collector 2, an incineration ash hopper 3, a humidifier 4, a filling machine 5, a feeder 6, a sludge hopper 7, and a blower B1.

[0011] The blower B1 is, for example, a device that supplies air (hereinafter also referred to as combustion air) to the incinerator 1 via a line L21. The line L21 is, for example, a pipe that connects the outlet side of the blower B1 with the inlet side of the combustion air in the incinerator 1. Specifically, the blower B1 is, for example, a device that has the function of blowing air, such as a fan or a blower.

[0012] The sludge hopper 7 temporarily stores sludge (dewatered cake) supplied via, for example, line L11. In other words, the sludge hopper 7 temporarily stores sludge before it is supplied to, for example, the incinerator 1. The line L11 is, for example, a pipe connecting upstream equipment of the incinerator 1 (for example, a dryer that dries the sludge) with the inlet side of the incinerator 1 for sludge.

[0013] The incinerator 1 is, for example, a fluidized bed incinerator that incinerates sludge supplied (put in) from a sludge hopper 7 via a line L12, and has a so-called fluidized bed 1a. The line L12 is, for example, a pipe that connects the sludge hopper 7 with the sludge inlet side of the incinerator 1. The following description will be given assuming that the incinerator 1 is a fluidized bed incinerator, but the incinerator 1 may be, for example, various types of incinerators other than a fluidized bed incinerator. The following description will be given assuming that the incineration ash used in this embodiment is incineration ash contained in the flue gas G1, but the incineration ash used in this embodiment may be, for example, ash extracted from the bottom of the incinerator 1, such as a stoker furnace.

[0014] The dust collector 2 is disposed, for example, downstream of the incinerator 1, and collects incineration ash (hereinafter also simply referred to as incineration ash) contained in the exhaust gas G1 supplied from the incinerator 1 via a line L1. The line L1 is, for example, a pipe connecting the outlet side of the exhaust gas G1 in the incinerator 1 with the inlet side of the dust collector 2. Specifically, the dust collector 2 may be, for example, a cyclone or a bag filter.

[0015] Then, the exhaust gas G1 that has passed through the dust collector 2 (the exhaust gas G1 after the incineration ash has been collected) is supplied to a downstream facility (not shown) of the dust collector 2, for example, via a line L2. The line L2 is, for example, a pipe that connects the outlet side of the exhaust gas G1 in the dust collector 2 with the downstream facility.

[0016] The incineration system 100 may, for example, be equipped with a downstream device, such as a dust collector 2, to remove SO 2 from the exhaust gas G1. X The incineration system 100 may include a smoke washing tower (not shown) that removes components such as carbon monoxide by incorporating them into smoke washing water, and a chimney (not shown) that discharges the exhaust gas G1 cleaned in the smoke washing tower to the outside. The incineration system 100 may also include a heat exchanger (not shown) that recovers the heat contained in the exhaust gas G1, for example, as equipment upstream of the dust collector 2 (equipment downstream of the incinerator 1).

[0017] The incineration ash collected in the dust collector 2 is supplied to each of the multiple incineration ash hoppers 3 via, for example, line L3. The line L3 is, for example, a pipe connecting the incineration ash outlet side of the dust collector 2 with each of the multiple incineration ash hoppers 3.

[0018] Specifically, the incineration ash collected by the dust collector 2 is supplied to, for example, one incineration ash hopper 3 (hereinafter also referred to as a specific incineration ash hopper 3) determined in a predetermined order from among the multiple incineration ash hoppers 3. The predetermined order is, for example, a predetermined order that the incineration ash is sequentially supplied to each of the multiple incineration ash hoppers 3. When the amount of incineration ash stored in the specific incineration ash hopper 3 reaches a predetermined threshold (hereinafter also referred to as a predetermined threshold), the next incineration ash collected by the dust collector 2 is supplied to, for example, the next incineration ash hopper 3 (hereinafter also simply referred to as another incineration ash hopper 3) determined in a predetermined order from among the multiple incineration ash hoppers 3.

[0019] That is, the line L3 supplies the incineration ash collected in the dust collector 2 to one incineration ash hopper 3, rather than supplying the incineration ash collected in the dust collector 2 to a plurality of incineration ash hoppers 3 in parallel (simultaneously).

[0020] As a result, the incineration system 100 in this embodiment can, for example, associate each incineration ash hopper 3 with the incineration ash stored in each incineration ash hopper 3, and can maintain a state in which information about the incineration ash stored in each incineration ash hopper 3 (for example, information such as the date and time when the ash was supplied to each incineration ash hopper 3 via line L3) can be identified. This allows workers to easily perform quality control of the incineration ash stored in each incineration ash hopper 3, for example.

[0021] Returning to Figure 1, each of the multiple incineration ash hoppers 3 temporarily stores incineration ash supplied from the dust collector 2 via, for example, line L3. The incineration ash supplied from each incineration ash hopper 3 is then supplied to the humidifier 4 via, for example, line L4. Line L4 is, for example, a pipe connecting each of the multiple incineration ash hoppers 3 to the humidifier 4. Specifically, each of the multiple incineration ash hoppers 3 is, for example, arranged in parallel with one another.

[0022] Note that, although the following description will be given assuming that the incineration ash supplied from each incineration ash hopper 3 is supplied to the humidifier 4, this is not limiting. Specifically, as shown in Figure 1, the incineration ash supplied from each incineration ash hopper 3 may be supplied directly to at least one of the filling machine 5 and the feeder 6 via line 4a. Line L4a is, for example, a pipe branching from line L4 and communicating with the filling machine 5 and the feeder 6. In other words, the incineration ash supplied from each incineration ash hopper 3 may be supplied directly to at least one of the filling machine 5 and the feeder 6, bypassing the humidifier 4, for example.

[0023] In addition, the following description will be given assuming that the incineration system 100 has three incineration ash hoppers 3 (incineration ash hopper 3a, incineration ash hopper 3b, and incineration ash hopper 3c) arranged in parallel, but this is not limiting. Specifically, the incineration system 100 may have, for example, two or four or more incineration ash hoppers 3 arranged in parallel, with a line L3 connecting the dust collector 2 to each of the two or four or more incineration ash hoppers 3, and a line L4 connecting each of the two or four or more incineration ash hoppers 3 to the humidifier 4. In addition, the incineration system 100 may have, for example, one incineration ash hopper 3, with a line L3 connecting the dust collector 2 to one incineration ash hopper 3, and a line L4 connecting one incineration ash hopper 3 to the humidifier 4. Below, an example configuration of the incineration ash hopper 3 will be described.

[0024] [Incineration ash hopper 3 in the first embodiment] Next, a configuration example of the incineration ash hopper 3 in the first embodiment will be described. Figure 2 is a diagram for explaining a configuration example of the incineration ash hopper 3 in the first embodiment.

[0025] 2, the incineration ash hopper 3 has, for example, a hopper body 31, a discharge mechanism 32, an ash sampling pipe 33a, an ash sampling pipe 33b, an opening / closing mechanism 34, and a gas supply pipe 35. Hereinafter, the ash sampling pipe 33a and the ash sampling pipe 33b will be collectively referred to simply as the ash sampling pipe 33.

[0026] The hopper body 31 has, for example, a hollow funnel shape whose diameter decreases toward the Z2 direction (downward). An ash supply pipe 31b is attached to the hopper body 31, for example, at the Z1 direction end (upper end), for supplying incineration ash into the hopper body 31 from the Z1 direction (above). That is, incineration ash supplied from the dust collector 2 via the line L3 is introduced, for example, through an opening 31a, which is a communication port with the ash supply pipe 31b at the Z1 direction end of the hopper body 31, and stored in the hopper body 31. An ash discharge pipe 31c is attached to the hopper body 31, for example, at the Z2 direction end (lower end), for discharge of incineration ash from the hopper body 31 to the outside of the hopper body 31 from the Z2 direction (below). Hereinafter, the opening 31a will also be referred to as a third supply port.

[0027] The discharge mechanism 32 is provided, for example, at the end (lower end) of the hopper body 31 on the Z2 direction side, and is a mechanism that discharges the incineration ash inside the hopper body 31 to the outside of the hopper body 31. Specifically, the discharge mechanism 32 may be, for example, a rotary valve that operates during the time period when the incineration ash is discharged from the hopper body 31 and stops operating during the time period when the incineration ash is stored inside the hopper body 31.

[0028] The ash sampling pipe 33a is, for example, a pipe that communicates with the ash supply pipe 31b. When an operator analyzes the components of the incineration ash moving through the ash supply pipe 31b, for example, the operator acquires (collects) the incineration ash discharged from the ash sampling pipe 33b (hereinafter also referred to as the incineration ash to be sampled).

[0029] The ash collecting pipe 33a may be provided with, for example, a valve (not shown) that can adjust the amount of incineration ash (incineration ash to be collected) discharged through the ash collecting pipe 33a.

[0030] The ash sampling pipe 33b is, for example, a pipe that communicates with the wall surface of the hopper body 31. When an operator, for example, analyzes the components of the incineration ash stored in the hopper body 31, he or she obtains (collects) the incineration ash (the incineration ash to be collected) discharged from the ash sampling pipe 33b.

[0031] Specifically, the ash collecting pipe 33b communicates with the wall surface of the hopper body 31, for example, on the Z1 direction side (upper end side) of the wall surface of the hopper body 31.

[0032] That is, when the ash collecting pipe 33b communicates with the Z2 direction side (lower end side) of the wall surface of the hopper body 31, the amount of incineration ash piled up above the incineration ash to be collected increases, and the incineration ash to be collected is consolidated within the hopper body 31. Therefore, in this case, in the hopper body 31, for example, a large amount of the incineration ash to be collected may be discharged from the ash collecting pipe 33b, which may pose a danger to workers.

[0033] Therefore, in the incineration system 100 of this embodiment, for example, the ash collection pipe 33b is connected to the wall surface of the hopper body 31 at a position where compaction of the incineration ash to be collected can be sufficiently suppressed.

[0034] As a result, the incineration system 100 in this embodiment can, for example, prevent large amounts of incineration ash to be collected from being discharged from the ash collection pipe 33b, thereby improving the safety of workers.

[0035] The incineration ash hopper 3 may have, for example, a plurality of ash collection pipes 33b. Specifically, for example, a plurality of ash collection pipes 33b may be attached to the wall surface of the hopper body 31.

[0036] This allows the worker to select an ash collection pipe 33b to collect the incineration ash (for example, an ash collection pipe 33b that can safely collect the incineration ash) depending on, for example, the amount of incineration ash stored in the hopper body 31.

[0037] The ash collecting pipe 33b may be provided with, for example, a valve (not shown) that can adjust the amount of incineration ash (incineration ash to be collected) discharged through the ash collecting pipe 33b.

[0038] The opening / closing mechanism 34 is provided, for example, at the end (upper end) of the hopper body 31 on the Z1 direction side, and is a mechanism for adjusting the supply of incineration ash into the hopper body 31. Specifically, the discharge mechanism 32 may be, for example, a slide gate that can be opened and closed by sliding along the X-axis direction. The slide gate is a mechanism that opens, for example, during the time period when incineration ash is being supplied into the hopper body 31, and closes during the time period when the supply of incineration ash into the hopper body 31 is stopped.

[0039] The opening and closing mechanism 34 may be configured to enable the supply of incineration ash from the opening 31a into the hopper body 31 by an operation other than sliding. Specifically, the opening and closing mechanism 34 may be connected to a rotating shaft (not shown) provided inside or outside the hopper body 31, and may rotate around the rotating shaft as the center of rotation to enable the supply of incineration ash from the opening 31a into the hopper body 31.

[0040] Furthermore, the opening / closing mechanism 34 may slide along a direction other than the X-axis direction, for example.

[0041] The opening and closing mechanism 34 may be operated by, for example, driving a motor (not shown) or an air cylinder (not shown).

[0042] The gas supply pipe 35 is, for example, a pipe that communicates with the wall surface of the hopper body 31. Hereinafter, the communication port with the gas supply pipe 35 in the wall surface of the hopper body 31 will also be referred to as a fourth supply port.

[0043] Then, for example, when the supply of incineration ash to the hopper body 31 is completed, in other words, when the amount of incineration ash supplied to the hopper body 31 reaches a predetermined threshold, the operator closes the opening / closing mechanism 34 to cover the opening 31a, and further fills the hopper body 31 with gas supplied from a gas supply device (not shown). The gas here is, for example, nitrogen, which has a specific gravity lighter than air. Below, we will explain the case where the gas is nitrogen.

[0044] That is, the incineration ash in the hopper body 31 absorbs moisture contained in the air present in the hopper body 31 (for example, air present in gaps between the incineration ash). Then, for example, a bridge of incineration ash may occur in the hopper body 31, which may prevent the incineration ash from being discharged sufficiently from the hopper body 31.

[0045] In particular, when calcium is supplied to sludge in an incinerator 1 or the like in order to increase the citrate-soluble phosphorus rate in the incineration ash, the incineration ash in the hopper body 31 will, for example, absorb more moisture contained in the air.

[0046] Therefore, in the incineration system 100 of this embodiment, for example, nitrogen is supplied from the gas supply pipe 35 to the inside of the hopper body 31, thereby replacing the air present inside the hopper body 31 with nitrogen.

[0047] As a result, the incineration system 100 in this embodiment can, for example, remove moisture present in the hopper body 31 from the hopper body 31, and suppress absorption of moisture by the incineration ash in the hopper body 31. Therefore, the incineration system 100 in this embodiment can, for example, suppress the occurrence of bridges of incineration ash in the hopper body 31.

[0048] In addition, the incineration system 100 in this embodiment can eliminate compaction of the incineration ash within the hopper body 31, for example, by supplying nitrogen from the gas supply pipe 35 into the hopper body 31.

[0049] In addition, the hopper body 31 may have, for example, a gas supply pipe 35 for supplying nitrogen for the purpose of removing air present in the hopper body 31, and a gas supply pipe 35 for supplying nitrogen for the purpose of eliminating compaction of the incineration ash within the hopper body 31, separately.

[0050] Each of the plurality of incineration ash hoppers 3 stores the incineration ash supplied from the dust collector 2 via the line L3, for example, in a predetermined order.

[0051] Specifically, in the example shown in Figure 2, the incineration ash supplied from the dust collector 2 via line L3 is first supplied to, for example, the incineration ash hopper 3a. Then, when the amount of incineration ash stored in the incineration ash hopper 3a reaches a predetermined threshold, the incineration ash next supplied from the dust collector 2 via line L3 is supplied to, for example, the incineration ash hopper 3b. Furthermore, when the amount of incineration ash stored in the incineration ash hopper 3b reaches a predetermined threshold, the incineration ash next supplied from the dust collector 2 via line L3 is supplied to, for example, the incineration ash hopper 3c. Thereafter, when the amount of incineration ash stored in the incineration ash hopper 3c reaches the predetermined threshold and the discharge of the incineration ash stored in the incineration ash hopper 3a has already been completed, the incineration ash next supplied from the dust collector 2 via line L3 is supplied again to, for example, the incineration ash hopper 3a.

[0052] That is, the incineration ash supplied from the dust collector 2 is supplied to only one incineration ash hopper 3, for example.

[0053] As a result, the incineration system 100 in this embodiment can maintain a state in which information about the incineration ash stored in each incineration ash hopper 3 can be identified, even in cases where the incineration ash supplied to each incineration ash hopper 3 needs to be stored for a long period of time, for example, due to the need to perform component analysis of the incineration ash stored in each incineration ash hopper 3.

[0054] Returning to FIG. 1, the humidifier 4 humidifies the incineration ash supplied from each of the multiple incineration ash hoppers 3, for example, via line L4. Specifically, the incineration ash to be humidified in the humidifier 4 is, for example, the incineration ash supplied from the incineration ash hopper 3 after component analysis, etc. has been completed. The incineration ash humidified by the humidifier 4 is then supplied to the filling machine 5, for example, via line L5. The line L5 is, for example, a pipe connecting the humidifier 4 and the filling machine 5. The incineration ash humidified by the humidifier 4 is then supplied to the feeder 6, for example, via line L6. The line L6 is, for example, a pipe connecting the humidifier 4 and the feeder 6.

[0055] That is, the incineration ash humidified by the humidifier 4 is supplied to a filling machine 5 or a feeder 6 depending on, for example, the use of the incineration ash and the transportation (shipping) method.

[0056] The incineration ash humidified by the humidifier 4 may be supplied to a destination other than the filling machine 5 and the feeder 6. An example of the configuration of the humidifier 4 will be described below.

[0057] [Humidifier 4 in the first embodiment] Next, a configuration example of the humidifier 4 in the first embodiment will be described. Fig. 3 is a diagram illustrating a configuration example of the humidifier 4 in the first embodiment.

[0058] As shown in FIG. 3, the humidifier 4 includes, for example, a humidifier main body 41, an ash supply pipe 42, a water supply pipe 43, an ash discharge pipe 44, a conveying device 45, a motor 46, and a measuring device M.

[0059] The humidifier main body 41 is, for example, a housing having a hollow rectangular shape extending along the X-axis direction.

[0060] An ash supply pipe 42 is attached to the humidifier body 41, for example, on the X2 side of the end face (upper end face) on the Z1 side, for supplying incineration ash from the Z1 side (above) into the humidifier body 41. The ash supply pipe 42 is, for example, a pipe that communicates with the line L3 and supplies the incineration ash supplied via the line L3 into the humidifier body 41. Hereinafter, the communication port with the ash supply pipe 42 on the end face on the Z1 side of the humidifier body 41 will also be referred to as the first supply port.

[0061] Furthermore, a water supply pipe 43 is attached to the humidifier body 41 on the Z1-side end face (upper end face) closer to the X1 direction (closer to the ash discharge pipe 44) than the ash supply pipe 42, for example, at the Z1-side end face (upper end face). The water supply pipe 43 supplies water supplied from a water supply device (not shown), for example, into the humidifier body 41. Hereinafter, the communication port with the water supply pipe 43 on the Z1-side end face of the humidifier body 41 will also be referred to as a second supply port.

[0062] An ash discharge pipe 44 is attached to the humidifier body 41, for example, on the Z2-side end face (lower end face) closer to the X1 direction than the water supply pipe 43, for discharging the incineration ash in the humidifier body 41 from the Z2-side (below) to the outside of the humidifier body 41. The ash discharge pipe 44 discharges the incineration ash in the humidifier body 41 to line L5 or line L6, for example. Hereinafter, the communication port with the ash discharge pipe 44 on the Z2-side end face of the humidifier body 41 will also be referred to as a first discharge port.

[0063] In the example shown in FIG. 1, in the incineration system 100, for example, a plurality of incineration ash hoppers 3 communicate with one humidifier 4 via a line L3.

[0064] As a result, in the incineration system 100 of this embodiment, for example, it is not necessary to install multiple humidifiers 4 in conjunction with the installation of multiple incineration ash hoppers 3. Therefore, in the incineration system 100 of this embodiment, it is possible to reduce, for example, the cost required for humidifying incineration ash (the cost required for purchasing and installing multiple humidifiers 4).

[0065] 1, in the incineration system 100, for example, a humidifier 4 is installed downstream of the multiple incineration ash hoppers 3. In other words, in the example shown in FIG. 1, the humidifier 4 humidifies the incineration ash stored in the multiple incineration ash hoppers 3.

[0066] As a result, in the incineration system 100 of this embodiment, for example, incineration ash after being humidified by the humidifier 4 is not supplied to the multiple incineration ash hoppers 3. Therefore, in the incineration system 100 of this embodiment, for example, it is possible to suppress the humidity of the incineration ash supplied to each incineration ash hopper 3, and it is possible to suppress the occurrence of bridges in the incineration ash hopper 3.

[0067] The conveying device 45 is, for example, a paddle-type screw conveyor, and has a conveyor shaft 45a and screw blades 45b. It agitates the incineration ash supplied from the ash supply pipe 42 and the water supplied from the water supply pipe 43, and supplies the incineration ash supplied from the ash supply pipe 42 to the X1 direction or the X2 direction.

[0068] Conveyor shaft 45a is, for example, a shaft extending along the X-axis direction (horizontal direction), and one end (the end on the X1 direction side) is extended outside humidifier main body 41 and rotatably supported by a support member (not shown). Conveyor shaft 45a rotates around its long axis by, for example, driving of motor 46 connected to the one end extended outside humidifier main body 41.

[0069] The screw blade 45b is attached to, for example, the outer periphery of the conveyor shaft 45a, and extends spirally toward the end of the conveyor shaft 45a on the X1 direction side (the ash discharge pipe 44 side).

[0070] The measuring device M is, for example, a measuring device that measures the stirring state (hereinafter also simply referred to as the stirring state) of the incineration ash and water by the conveying device 45. Specifically, the measuring device M measures the stirring state of the incineration ash at the position where the measuring device M is attached, among the positions in the X-axis direction inside the humidifier main body 41.

[0071] More specifically, the measuring device M has, for example, a photographing device (not shown) that photographs the incineration ash inside the humidifier main body 41, and measures the stirring state from the amount of water adhering to the surface of the incineration ash reflected in image data (not shown) photographed by the photographing device. Specifically, the measuring device M obtains a measurement result that indicates, for example, that the greater the amount of water adhering to the surface of the incineration ash, the less progress is being made in stirring the incineration ash and water by the conveying device 45. Furthermore, the measuring device M obtains a measurement result that indicates, for example, that the less water adhering to the surface of the incineration ash, the more progress is being made in stirring the incineration ash and water by the conveying device 45.

[0072] The measuring device M may, for example, have a measuring instrument (not shown) that measures the moisture content of the incineration ash in the humidifier main body 41, and obtain a measurement result indicating whether the moisture content of the incineration ash measured by the measuring instrument is within a predetermined range (i.e., within the range of the target moisture content).

[0073] 3, the measuring device M is attached to a surface (ceiling surface) on the Z1 direction side inside the humidifier body 41, but this is not limiting. Specifically, the measuring device M may be attached to another surface (for example, a wall surface) inside the humidifier body 41, for example.

[0074] In the incineration system 100, for example, the conveying direction of the incineration ash by the conveying device 45 (the rotation direction of the conveyor shaft 45a) is adjusted according to the measurement result of the stirring state measured by the measuring device M.

[0075] Specifically, for example, if the operator determines that the stirring state measured by the measuring device M does not satisfy a predetermined condition (hereinafter also referred to as a predetermined condition), in other words, if the operator determines that the incineration ash and water are not being sufficiently stirred by the conveying device 45, the operator controls the motor 46 to reverse the conveying direction of the incineration ash and convey the incineration ash in the humidifier body 41 toward the X2 direction (i.e., the direction opposite to the direction toward the ash discharge pipe 44). On the other hand, if the operator determines that the stirring state measured by the measuring device M satisfies a predetermined condition, in other words, if the operator determines that the incineration ash and water are being sufficiently stirred by the conveying device 45, the operator continues to convey the incineration ash in the humidifier body 41 toward the X1 direction without reversing the conveying direction of the incineration ash.

[0076] As a result, in the incineration system 100 of this embodiment, if it is determined that the incineration ash and water are not being sufficiently agitated by the transport device 45, it is possible to further agitate the incineration ash and water. Therefore, in the incineration system 100 of this embodiment, even if the water supply pressure from the water supply device is not constant and unevenness occurs in the progress of agitation of the incineration ash and water, it is possible to sufficiently and evenly humidify the incineration ash in the humidifier 4.

[0077] The water supply pipe 43 may supply, for example, water supplied from a water supply device, as well as chemicals such as a binder supplied from a chemical supply device (not shown), into the humidifier body 41.

[0078] As a result, in the incineration system 100 of this embodiment, it is possible to prevent the scattering of incineration ash during transportation, for example.

[0079] In addition, in the incineration system 100 of this embodiment, for example, it is possible to reduce the amount of water that needs to be added to the incineration ash in the humidifier 4, making it possible to improve transportation efficiency while preventing the incineration ash from scattering during transportation.

[0080] Furthermore, for example, a plurality of measuring devices M may be attached to the humidifier main body 41. Then, for example, the operator may determine whether or not the stirring state measured by each of the plurality of measuring devices M satisfies a predetermined condition for each of the plurality of measuring devices M. Then, for example, when the operator determines that the stirring state measured by at least one of the plurality of measuring devices M satisfies a predetermined condition, the operator may reverse the conveying direction of the incineration ash by the conveying device 45.

[0081] Furthermore, the humidifier body 41 may be provided with a plurality of water supply pipes 43 for supplying water to the incineration ash in the humidifier body 41, for example.

[0082] In addition, in order to measure the stirring state, an optical method such as a photometer may be used, and any known measuring means may be used.

[0083] Returning to Figure 1, the filling machine 5 fills the incineration ash supplied from the humidifier 4 via the line L5 into a predetermined bag (not shown) or a predetermined container (not shown). The predetermined bag may be, for example, a flexible container pack. The predetermined container may be, for example, a container.

[0084] That is, the filling machine 5 prepares the incineration ash supplied from the humidifier 4 via the line L5, for example, so that it can be easily transported.

[0085] In the incineration system 100, for example, the incineration ash supplied from the humidifier 4 may be granulated in a granulator (not shown) and then supplied to the filling machine 5.

[0086] Furthermore, the filling machine 5 may have the same configuration as the incineration ash hopper 3 described with reference to FIG.

[0087] The feeder 6 supplies the incineration ash supplied from the humidifier 4 via the line L6 to a supply destination. The supply destination may be, for example, a means of transporting the incineration ash. Specifically, the means of transporting the incineration ash may be, for example, the loading platform of a vehicle (not shown) such as a truck. The following describes the case where the supply destination is the loading platform of a vehicle.

[0088] That is, the feeder 6 prepares the incineration ash supplied from the humidifier 4 via the line L6, for example, so that it can be easily transported.

[0089] The supply destination may be, for example, a direct supply of incineration ash from the humidifier 4. An example of the configuration of the feeder 6 will be described below.

[0090] [Slicer 6 in the first embodiment] Next, a configuration example of the cutter 6 in the first embodiment will be described. Figure 4 is a diagram illustrating a configuration example of the cutter 6 in the first embodiment.

[0091] As shown in FIG. 4, the cutter 6 includes, for example, a cutter body 61, an ash supply pipe 62, an ash discharge pipe 63, a conveying device 64, and a motor 65.

[0092] The cutter body 61 is, for example, a housing having a hollow rectangular shape extending along the X-axis direction.

[0093] An ash supply pipe 62 is attached to the cutter body 61, for example, on the X2 side of the end face (upper end face) on the Z1 side, for supplying incineration ash from the Z1 side (above) into the cutter body 61. The ash supply pipe 62 communicates with, for example, line L6, and supplies incineration ash supplied via line L6 into the cutter body 61. Hereinafter, the communication port with the ash supply pipe 62 on the end face on the Z1 side of the cutter body 61 will also be referred to as a fifth supply port.

[0094] In addition, an ash discharge pipe 63 is attached to the cutter body 61, for example, on the X1 side of the ash supply pipe 62 at the end face (lower end face) on the Z2 side, which discharges the incineration ash in the cutter body 61 from the Z2 side (below) to the outside of the cutter body 61. Hereinafter, the communication port with the ash discharge pipe 63 at the end face on the Z2 side of the cutter body 61 will also be referred to as the second discharge port.

[0095] Specifically, in the example shown in Fig. 4, for example, three ash discharge pipes 63 (ash discharge pipe 63a, ash discharge pipe 63b, and ash discharge pipe 63c) are provided in the cutter body 61. More specifically, in the example shown in Fig. 4, the ash discharge pipe 63a is provided, for example, on the X2 side of the ash supply pipe 62, the ash discharge pipe 63b is provided, for example, on the X1 side of the ash supply pipe 62, and the ash discharge pipe 63c is provided, for example, on the X1 side of the ash discharge pipe 63b.

[0096] The following description will be given of a case where three ash discharge pipes 63 are provided in the cutter body 61, but this is not limiting. Specifically, the cutter body 61 may be provided with, for example, a number of ash discharge pipes 63 other than three.

[0097] The conveying device 64 is, for example, a screw conveyor, and has a screw shaft 64a and screw blades 64b, and supplies the incineration ash supplied from the ash supply pipe 62 to the X1 direction side or the X2 direction side.

[0098] The screw shaft 64a is, for example, a shaft extending along the X-axis direction (horizontal direction), and one end (the end on the X1 direction side) is led out of the extrusion machine main body 61 and rotatably supported by a support member (not shown). The screw shaft 64a rotates around its long axis by, for example, driving a motor 65 connected to the one end led out of the extrusion machine main body 61.

[0099] The screw blade 64b is attached to, for example, the outer periphery of the screw shaft 64a, and extends spirally toward the end of the screw shaft 64a on the X1 direction side (the ash discharge pipe 63 side).

[0100] That is, for example, when the incineration ash discharged from the excavator body 61 is supplied to the loading platform of a vehicle, it is preferable to load the incineration ash as evenly as possible on the loading platform. Therefore, the worker, for example, appropriately switches the ash discharge pipe 63 that discharges the incineration ash to be supplied to the loading platform.

[0101] Specifically, for example, if the operator is to prioritize the discharge of incineration ash from the ash discharge pipe 63a, which is located on the X2 side of the ash supply pipe 62, the operator adjusts the conveying direction of the incineration ash by the conveying device 64 (the rotation direction of the screw shaft 64a) so that the incineration ash in the extruder body 61 is conveyed in the X2 direction. Also, for example, if the operator is to prioritize the discharge of incineration ash from the ash discharge pipe 63b or ash discharge pipe 63c, which are located on the X1 side of the ash supply pipe 62, the operator adjusts the conveying direction of the incineration ash by the conveying device 64 (the rotation direction of the screw shaft 64a) so that the incineration ash in the extruder body 61 is conveyed in the X1 direction.

[0102] As a result, in the incineration system 100, for example, it becomes possible to load the incineration ash evenly on the loading platform of the vehicle without having to move the vehicle.

[0103] Each of the multiple ash discharge pipes 63 may be provided with, for example, a valve (not shown). In the incineration system 100, the valve provided in each of the multiple ash discharge pipes 63 may be controlled to open (for example, fully open) or close (for example, fully close), thereby switching the ash discharge pipe 63 that discharges incineration ash.

[0104] Specifically, the worker may discharge the incineration ash from the ash discharge pipe 63a by, for example, controlling the opening of the valve provided on the ash discharge pipe 63a (for example, controlling it to be fully open) and controlling the closing of the valve provided on the ash discharge pipe 63b and the valve provided on the ash discharge pipe 63c (for example, controlling it to be fully closed).

[0105] In addition, the worker may discharge the incineration ash from the ash discharge pipe 63b by, for example, controlling the opening of the valve provided on the ash discharge pipe 63b (for example, controlling it to be fully open) and controlling the closing of the valve provided on the ash discharge pipe 63a and the valve provided on the ash discharge pipe 63c (for example, controlling it to be fully closed).

[0106] In addition, the worker may discharge the incineration ash from the ash discharge pipe 63c by, for example, controlling the opening of the valve provided on the ash discharge pipe 63c (for example, controlling it to be fully open) and controlling the closing of the valve provided on the ash discharge pipe 63a and the valve provided on the ash discharge pipe 63b (for example, controlling it to be fully closed).

[0107] 4, a case has been described in which some of the ash discharge pipes 63 (ash discharge pipe 63a) are provided on the X2 side of the ash supply pipe 62, and other ash discharge pipes 63 (ash discharge pipe 63b and ash discharge pipe 63c) are provided on the X1 side of the ash supply pipe 62, but this is not limiting. Specifically, all of the ash discharge pipes 63 may be provided on the X1 side of the ash supply pipe 62, or may be provided on the X2 side of the ash supply pipe 62, for example.

[0108] [Functions of the control device 10 in the first embodiment] Next, the functions of the control device 10 in the first embodiment will be described. Figure 5 is a diagram for explaining the functions of the control device 10 in the first embodiment.

[0109] The incineration system 100 further includes, for example, a control device 10, as shown in FIG.

[0110] The control device 10 controls, for example, valves V1, V2, and V3 provided on line L3 and valves V4, V5, and V6 provided on line L4, thereby switching the destination of the incineration ash supplied from the dust collector 2 via line L3 between incineration ash hopper 3a, incineration ash hopper 3b, and incineration ash hopper 3c (hereinafter also referred to as hopper switching control).

[0111] Specifically, the control device 10 controls the valves V1 and V4 to be open (for example, fully open) and the valves V2, V3, V5, and V6 to be closed (for example, fully closed), thereby supplying the incineration ash supplied from the dust collector 2 via the line L3 to the incineration ash hopper 3a. Also, the control device 10 controls the valves V2 and V5 to be open (for example, fully open) and the valves V1, V3, V4, and V6 to be closed (for example, fully closed), thereby supplying the incineration ash supplied from the dust collector 2 via the line L3 to the incineration ash hopper 3b. The control device 10 also controls the valves V3 and V6 to open (for example, fully open) and the valves V1, V2, V4, and V5 to close (for example, fully close), thereby supplying the incineration ash supplied from the dust collector 2 via line L3 to the incineration ash hopper 3c. Hereinafter, the valves V1, V2, V3, V4, V5, and V6 will be collectively referred to simply as valves V.

[0112] The control device 10 may, for example, control the valve V7 provided downstream of the branch point of the line L4 with the line L4a and the valve V8 provided on the line L4a to switch the supply destination of the incineration ash supplied from at least one of the multiple incineration ash hoppers 3 via the line L4 between the humidifier 4 and the filling machine 5 or the feeder 6. The control device 10 may also, for example, control the valve V9 provided downstream of the branch point of the line L4a (the branch point of the pipe communicating with the filling machine 5 and the pipe communicating with the feeder 6) and upstream of the filling machine 5, and the valve V10 provided downstream of the branch point of the line L4a and upstream of the feeder 6 to switch the supply destination of the incineration ash supplied from at least one of the multiple incineration ash hoppers 3 via the line L4 and the line L4a between the filling machine 5 and the feeder 6.

[0113] In addition, the control device 10 controls the motor 46 according to the stirring state (stirring state of incineration ash and water) measured by a measuring device M provided in the humidifier 4, thereby controlling the conveying direction of the incineration ash by the conveying device 45 (rotation direction of the conveyor shaft 45a) (hereinafter also referred to as conveying direction control).

[0114] Specifically, for example, when the control device 10 determines that the stirring state measured by the measuring device M does not satisfy a predetermined condition, in other words, when it determines that the incineration ash and water are not being sufficiently stirred by the conveying device 45, it controls the motor 46 to change the direction of conveyance of the incineration ash to the X2 direction, and conveys the incineration ash in the humidifier body 41 in the X2 direction. On the other hand, when the control device 10 determines that the stirring state measured by the measuring device M satisfies a predetermined condition, in other words, when it determines that the incineration ash and water are being sufficiently stirred by the conveying device 45, it controls the motor 46 to change the direction of conveyance of the incineration ash to the X1 direction, and conveys the incineration ash in the humidifier body 41 in the X1 direction.

[0115] Furthermore, the control device 10 performs control (hereinafter also referred to as information management control) to manage, for each of the multiple incineration ash hoppers 3, at least one of information regarding the supply date and time of incineration ash to each incineration ash hopper 3 (hereinafter also referred to as first information) and information regarding the supply amount of incineration ash to each incineration ash hopper 3 (hereinafter also referred to as second information). The first information includes, for example, information indicating at least one of the time when the supply of incineration ash to each incineration ash hopper 3 started and the time when the supply of incineration ash to each incineration ash hopper 3 ended. The second information includes, for example, information indicating the supply amount of incineration ash from the time when the supply of incineration ash to each incineration ash hopper 3 started to the time when the supply of incineration ash to each incineration ash hopper 3 ended.

[0116] In addition, the control device 10 may switch the ash discharge pipe 63 that discharges incineration ash from the excavator main body 61, for example, by controlling the opening (e.g., control to fully close) or closing (e.g., control to fully close) of the valves provided on each of the multiple ash discharge pipes 63.

[0117] For example, the opening and closing of each valve may be controlled at predetermined time intervals. Specifically, while rotating the screw shaft 64a so that the incineration ash is transported in the X2 direction, for a first predetermined time, the valve provided on the ash discharge pipe 63a (hereinafter referred to as the first valve) is fully opened, and the valves provided on the ash discharge pipe 63b (hereinafter referred to as the second valve) and the valves provided on the ash discharge pipe 63c (hereinafter referred to as the third valve) are fully closed. Then, after the first predetermined time has elapsed, while rotating the screw shaft 64a so that the incineration ash is transported in the X1 direction, for a second predetermined time, the second valve is fully opened and the first and third valves are fully closed. Then, after the second predetermined time has elapsed, while rotating the screw shaft 64a so that the incineration ash is transported in the X1 direction, for a third predetermined time, the third valve is fully opened and the first and second valves are fully closed. Thereafter, the above valve opening and closing processes and the transport of the incineration ash are repeated until the discharge of the incineration ash is completed. The first to third predetermined times are times that are determined appropriately, and may be equal to each other.

[0118] The control device 10 may also adjust the ash discharge pipe 63, through which the incineration ash in the excavator body 61 is preferentially discharged, by, for example, appropriately changing the conveying direction of the incineration ash by the conveying device 64 (the rotation direction of the screw shaft 64a). The configuration of the control device 10 in the first embodiment will be described below.

[0119] [Hardware Configuration of the Control Device 10 in the First Embodiment] 6 is a diagram illustrating the hardware configuration of the control device 10 in the first embodiment. Hereinafter, the various controls performed by the control device 10 will also be collectively referred to as hopper switching control, etc.

[0120] The control device 10 is, for example, an electronic device having an electronic circuit, as shown in Fig. 6. Specifically, the control device 10 is, for example, a computer device having a CPU 101 which is a processor, a memory 102, a communication device 103, and a storage medium 104. Each unit is connected to each other, for example, via a bus 105.

[0121] The storage medium 104 has, for example, a program storage area (not shown) that stores a program 110 for performing hopper switching control, etc. The storage medium 104 also has, for example, an information storage area 130 (hereinafter also referred to as a storage unit 130) that stores information used when performing hopper switching control, etc. The storage medium 104 may be, for example, an HDD (Hard Disk Drive) or an SSD (Solid State Drive).

[0122] The CPU 101 executes a program 110 loaded from the storage medium 104 into the memory 102, thereby performing hopper switching control and the like.

[0123] The communication device 103 accesses an operation terminal (not shown) through which an operator inputs necessary information, for example, via a network (not shown) such as the Internet.

[0124] The control device 10 may have, for example, an FPGA (Field Programmable Gate Array) or an ASIC (Application Specific Integrated Circuit). The control device 10 may also include, for example, a PIC (Peripheral Interface Controller). Hopper switching control and the like may be performed by, for example, the FPGA or ASIC.

[0125] In addition, the following description will be given of a case where hopper switching control and the like are performed by one control device 10, but the present invention is not limited to this. Specifically, hopper switching control and the like may be performed in a distributed manner by a plurality of control devices, for example.

[0126] [Hopper switching control in the first embodiment] Next, the hopper switching control in the first embodiment will be described. Fig. 7 is a flowchart illustrating the hopper switching control in the first embodiment. Below, the case where the hopper switching control is performed by the control device 10 will be described, but the hopper switching control may also be performed manually by an operator, for example.

[0127] The control device 10 controls, for example, each valve V to supply the incineration ash supplied from the dust collector 2 via the line L3 to a specific incineration ash hopper 3 (step S1 in FIG. 7).

[0128] Then, the control device 10 waits, for example, until the amount of incineration ash supplied to the specific incineration ash hopper 3 reaches a predetermined threshold value (NO in step S2 in FIG. 7).

[0129] Thereafter, if it is determined that the amount of incineration ash supplied in a specific incineration ash hopper 3 has reached a predetermined threshold (YES in step S2 of FIG. 7), the control device 10 identifies another incineration ash hopper 3 that will supply incineration ash next to the specific incineration ash hopper 3, for example, according to a predetermined order (step S3 of FIG. 7).

[0130] Then, the control device 10 controls the valve V, for example, to supply the incineration ash supplied from the dust collector 2 via the line L3 to another incineration ash hopper 3 (step S1 in FIG. 7).

[0131] [Transport Direction Control in the First Embodiment] Next, the conveying direction control in the first embodiment will be described. Fig. 8 is a flowchart illustrating the conveying direction control in the first embodiment. Below, the case where the conveying direction control is performed by the control device 10 will be described, but the conveying direction control may also be performed manually by an operator, for example.

[0132] In addition, the control device 10 acquires the stirring state (stirring state of incineration ash and water) measured by, for example, a measuring device M provided in the humidifier 4, and determines whether the acquired stirring state satisfies predetermined conditions (step S11 in FIG. 8).

[0133] As a result, if it is determined that the acquired stirring state satisfies the predetermined conditions (YES in step S11 of Figure 8), the control device 10, for example, maintains the conveying direction of the incineration ash by the conveying device 45 (the rotation direction of the conveyor shaft 45a) in the conveying direction in which the incineration ash is conveyed to the ash discharge pipe 44.

[0134] On the other hand, if it is determined that the acquired stirring state does not satisfy the predetermined conditions (NO in step S11 in Figure 8), the control device 10 reverses the conveying direction of the incineration ash by the conveying device 45 (the rotation direction of the conveyor shaft 45a) by, for example, controlling the motor 46 (step S12 in Figure 8).

[0135] In this case, the control device 10 may, for example, return the transport direction of the incineration ash by the transport device 45 to its original direction (the transport direction in which the incineration ash is transported to the ash discharge pipe 44) in response to the elapse of a predetermined time period after the transport direction of the incineration ash by the transport device 45 is reversed.

[0136] [Information Management Control in the First Embodiment] Next, the information management control in the first embodiment will be described. Fig. 9 is a flowchart illustrating the information management control in the first embodiment. Below, the case where the information management control is performed by the control device 10 will be described, but the information management control may also be performed manually by an operator, for example.

[0137] The control device 10 waits, for example, until the incineration ash supplied from the dust collector 2 via the line L3 is supplied to a specific incineration ash hopper 3 (NO in step S21 in FIG. 9).

[0138] Then, when the incineration ash supplied from the dust collector 2 via the line L3 is supplied to a specific incineration ash hopper 3 (YES in step S21 of FIG. 9), the control device 10 acquires, for example, information on the generation history of the incineration ash thrown into the specific incineration ash hopper 3 (hereinafter also referred to as history information) (step S22 of FIG. 9). The history information is, for example, at least one of first information on the date and time when the incineration ash was fed to the specific incineration ash hopper 3, and second information on the amount of incineration ash fed to the specific incineration ash hopper 3. The first information is, for example, information indicating the date and time when the incineration ash was actually fed to the specific incineration ash hopper 3. Furthermore, the second information is, for example, information indicating the amount of incineration ash actually fed to the specific incineration ash hopper 3. Note that the history information may be other information as long as it is possible to identify the sludge before incineration of the incineration ash thrown into the incineration ash hopper 3.

[0139] Thereafter, the control device 10 stores, for example, the history information acquired in step S22 in the information storage area 130 (step S23 in FIG. 9).

[0140] Here, in step S22, the control device 10 may acquire, for example, information (hereinafter also referred to as third information) regarding the incineration time of sludge (hereinafter also referred to as specific sludge) before incineration of incineration ash (hereinafter also referred to as specific incineration ash) supplied to a specific incineration ash hopper 3. The third information is, for example, information indicating the incineration time actually required for the specific sludge. Then, the control device 10 may calculate, for example, information (hereinafter also referred to as fourth information) indicating the date and time obtained by subtracting the time indicated by the third information from the supply date and time indicated by the first information acquired in step S22, as information indicating the date and time when the specific sludge was supplied to the incineration system 100.

[0141] Thereafter, the control device 10 may store the calculated fourth information in the information storage area 130 in step S23, for example.

[0142] As a result, the incineration system 100 in this embodiment can manage, for example, information about the incineration ash stored in each incineration ash hopper 3 in association with information about the sludge from the incineration ash before incineration. Therefore, even if a problem occurs with the incineration ash stored in each incineration ash hopper 3 (for example, a problem with the components contained in the incineration ash), the worker can easily identify the sludge from the incineration ash before incineration.

[0143] Specifically, the historical information stored in the information storage area 130 is, for example, historical information about the date and time when incineration ash was supplied to the incineration ash hopper 3. Therefore, the control device 10 can identify the date and time when the specific sludge was introduced into the incinerator 1 (hereinafter also referred to as the specific introduction date and time) by performing a process (hereinafter also simply referred to as the "back-calculation process") to calculate backward the incineration time of the specific sludge in the incinerator 1 based on the date and time when the specific incineration ash was supplied to the incineration ash hopper 3. The date and time when the sludge was introduced into the incinerator 1 is, for example, an example of information (fourth information) about the time when the sludge was supplied to the incinerator 1.

[0144] The control device 10 can then identify the specific sludge (for example, the identification information of the specific sludge) by, for example, comparing the specific input date and time with information (hereinafter also referred to as management information) that manages the identification information of each sludge input into the incinerator 1 at each date and time. In this regard, the control device 10 can perform the back-calculation process more accurately by also using, for example, information about the incineration time of the specific sludge (third information), thereby making it possible to more accurately identify the specific sludge.

[0145] The third information may be information indicating, for example, the total time of at least one of the time that the specific sludge was stored in the sludge hopper 7, the time required to transport the specific sludge between the sludge hopper 7 and the incinerator 1, and the time from when the specific incineration ash was generated in the incinerator 1 to when it was collected in the dust collector 2, and the time it took for the specific sludge to be incinerated in the incinerator 1.

[0146] As a result, the incineration system 100 in this embodiment can, for example, more accurately associate and manage information about the incineration ash stored in each incineration ash hopper 3 with information about the sludge before the incineration of the incineration ash.

[0147] Thus, the incineration system 100 of this embodiment includes, for example, an incinerator 1 that incinerates sludge, and one or more incineration ash hoppers 3 that store incineration ash supplied from the incinerator 1. In the incineration system 100 of this embodiment, each of the one or more incineration ash hoppers 3 stores incineration ash, for example, in a predetermined order.

[0148] Specifically, the incineration system 100 in this embodiment further includes a control device 10 that controls the supply of incineration ash to each of one or more incineration ash hoppers 3 in a predetermined order, for example. In the incineration system 100 in this embodiment, the control device 10 acquires, for each of the multiple incineration ash hoppers 3, history information regarding the generation history of incineration ash that is dumped into the incineration ash hopper 3, and stores the acquired history information in the information storage area 130.

[0149] Furthermore, in the incineration system 100 of this embodiment, the control device 10 identifies the sludge in the incineration ash that has been put into the incineration ash hopper 3 before incineration, for example, based on the acquired history information.

[0150] In addition, in the incineration system 100 of this embodiment, the historical information is, for example, information for each of multiple incineration ash hoppers 3, and is at least one of first information regarding the date and time when incineration ash is supplied to each incineration ash hopper 3 and second information regarding the amount of incineration ash supplied to each incineration ash hopper 3.

[0151] In addition, in the incineration system 100 of this embodiment, the control device 10 calculates fourth information regarding the supply time of sludge to the incinerator 1 based on, for example, any of the acquired information and third information regarding the incineration time of sludge in the incinerator 1, and stores the calculated fourth information in the information storage area 130.

[0152] The storage medium for storing each of the first to fourth information may be, for example, a storage medium such as an IC (Integrated Circuit) tag. When each of the first to fourth information is stored in an IC tag, the IC tag may be attached to the incineration ash hopper 3 or the bag. The storage medium may be, for example, a physical storage medium (such as a plastic panel on which information can be written with ink, etc.) instead of an electronic storage medium.

[0153] Furthermore, in the incineration system 100 of this embodiment, each of the one or more incineration ash hoppers 3 has an ash collection pipe 33 that is provided, for example, on the side wall at the upper end and that discharges the incineration ash in each incineration ash hopper 3.

[0154] Moreover, the incineration system 100 in this embodiment further includes, for example, a humidifier 4 that humidifies the incineration ash supplied from at least one of the one or more incineration ash hoppers 3.

[0155] In addition, in the incineration system 100 of this embodiment, the humidifier 4 has, for example, an ash supply pipe 42 that is provided at one end in the longitudinal direction and supplies incineration ash to the inside, a water supply pipe 43 that is provided at the other end in the longitudinal direction from the ash supply pipe 42 and supplies water supplied from a supply device to the incineration ash, a conveying device 45 (hereinafter also referred to as the first conveying device) that extends along the longitudinal direction and stirs the incineration ash supplied from the ash supply pipe 42 and the water supplied from the water supply pipe 43 and conveys the incineration ash from one end to the other end, a measuring device M that is provided at the other end from the water supply pipe 43 and measures the stirring state of the incineration ash and water, and an ash discharge pipe 44 that is provided at the other end from the measuring device M and discharges the incineration ash conveyed by the conveying device 45.

[0156] In the incineration system 100 of this embodiment, the control device 10 controls the direction in which the incineration ash is conveyed by the conveying device 45, for example, in accordance with the stirring state measured by the measuring device M.

[0157] Furthermore, in the incineration system 100 of this embodiment, each of the one or more incineration ash hoppers 3 has, for example, an opening 31a at the upper end through which incineration ash is supplied to the inside, a gas supply pipe 35 at the lower end, which is provided on the wall surface on the lower end side and supplies a predetermined gas supplied by a supply device to the inside, and an opening / closing mechanism 34 that can open and close the opening 31a.

[0158] The incineration system 100 of this embodiment also has a feeder 6 that supplies the incineration ash supplied from at least one of the one or more incineration ash hoppers 3 or the humidifier 4 to a supply destination.
