[0009] Hereinafter, a furnace facility according to an embodiment of the present disclosure will be described with reference to the drawings.

[0010] <Basic structure of furnace equipment> The furnace facility 100 according to an embodiment of the present disclosure is a carbonization furnace that produces biochar using a material to be carbonized W, such as woody biomass, as a raw material, or a reactor that produces biofuel. Hereinafter, the furnace facility 100 according to an embodiment of the present disclosure will be described using the furnace facility 100 as a carbonization furnace as an example.

[0011] As shown in Fig. 1, the furnace equipment 100 is a mobile furnace that can be mounted on a vehicle 10 such as a truck. Therefore, the furnace equipment 100 is provided with a connecting part (not shown) that is used to connect and fix the furnace equipment 10 to the vehicle 10.

[0012] As shown in FIGS. 2 and 3, the furnace equipment 100 includes a furnace body 110, a floor 140, a chimney 150, an induced draft fan (fan) 161, and a control unit 190.

[0013] The control unit 190 is a device that executes control necessary for the operation of the furnace equipment 100, such as processing information acquired from each device provided in the furnace equipment 100 and transmitting and receiving signals to and from each device. The control unit 190 (controller) includes, for example, a CPU (Central Processing Unit: Processor), a main memory, a secondary storage, etc. Furthermore, the control unit 190 may include a communication unit for transmitting and receiving information to and from other devices. Here, the other devices include, for example, each valve, and a temperature sensor, flow rate sensor, etc. required for controlling each valve provided at each location. The main storage device is composed of writable memory such as cache memory and RAM (Random Access Memory), and is used as a working area for reading the execution program of the CPU and writing the processing data by the execution program. A secondary storage device is a non-transitory computer-readable storage medium, such as a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, or a semiconductor memory. For example, a series of processes for realizing various functions is stored in a secondary storage device in the form of a program, and the CPU reads this program into the main storage device and executes information processing and arithmetic operations to realize various functions. Note that the program may be pre-installed in the secondary storage device, provided in a state stored in a computer-readable storage medium, or distributed via wired or wireless communication means. Examples of computer-readable storage media include magnetic disks, magneto-optical disks, CD-ROMs, DVD-ROMs, and semiconductor memories.

[0014] The furnace body 110 is a rectangular parallelepiped container having a furnace space S0 formed therein. The shape of the furnace body 110 is not limited to a rectangular parallelepiped shape. The furnace body 110 has a vessel portion 120 and a lid portion 130 .

[0015] The container 120 is a container with an open top. The container portion 120 has a bottom 121 and a peripheral wall 122 . The bottom 121 is a substantially rectangular plate-like portion extending in a horizontal plane (in the front-rear and left-right directions in the cases of FIGS. 2 and 3). The peripheral wall 122 is a wall that stands upward from the entire peripheral edge of the bottom 121. The peripheral wall 122 also serves as a peripheral wall portion of the furnace body 110. The container portion 120 is formed by integrating the bottom 121 and the peripheral wall 122 together.

[0016] The lid 130 is a lid for closing the opening on the top surface of the container 120 . The lid 130 provided on the top of the vessel 120 closes the opening on the top surface of the vessel 120, thereby forming a furnace space S0 inside the furnace body 110.

[0017] The furnace space S0 is divided vertically by a floor 140. The upper space of the furnace space S0 divided by the floor 140 is referred to as an upper space S1, and the lower space thereof is referred to as a lower space S2. The upper space S1 is a space for storing the material W to be carbonized. The floor 140 is a substantially rectangular plate-like portion that extends in a horizontal plane inside the container portion 120. The floor 140 is provided at a height of several tens of centimeters from the bottom 121 of the container portion 120, for example. The floor 140 has a communication portion 141 . The communication section 141 is a section that communicates the upper space S1 with the lower space S2. The communication section 141 is exemplified by a large number of holes (through holes) formed in the floor 140. The purpose of providing the communication part 141 is to guide gas containing combustion exhaust gas, which will be described later, from the upper space S1 to the lower space S2 without causing the material to be carbonized W or carbonized material stored in the upper space S1 to fall into the lower space S2. Therefore, as long as this purpose can be achieved, the specific shape and number of the communication part 141 are not particularly limited.

[0018] The peripheral wall 122 of the container portion 120 has at least one intake opening 122a and at least one insertion opening 122b. The intake opening 122a is an opening (through hole) that connects the upper space S1 to the outside of the container portion 120. The intake opening 122a is an opening for taking in combustion air (air outside the container portion 120) from the outside of the container portion 120 into the upper space S1. In the case of FIG. 2, the intake opening 122a is a rectangular opening extending in the front-rear direction. In addition, in the cases of FIGS. 2 and 3, the intake openings 122a are provided in the upper parts of both left and right walls of the peripheral wall 122. The insertion opening 122b is an opening (through hole) that connects the lower space S2 to the outside of the container part 120. The insertion opening 122b is an opening for inserting an ignition burner 183 from the outside of the container part 120 into the upper space S1. In the case of Fig. 2, the insertion opening 122b is provided in the lower part of the peripheral wall 122, and is a circular opening.

[0019] A chimney 150 is provided on each side surface of the container 120 (both side surfaces in the front-rear direction in the case of FIG. 2). The chimney 150 is a part in which an exhaust flow path P1 is formed. The chimney 150 extends in the vertical direction along the side surface of the container part 120, and for example, the opening at the top (the outlet of the exhaust flow path P1) is located higher than the lid part . The exhaust flow path P1 has a lower portion connected to the lower space S2 and an upper portion connected to the outside of the furnace body 110. In other words, the exhaust flow path P1 is a flow path that connects the lower space S2 with the outside of the furnace body 110.

[0020] An induced draft fan 161 is installed in each exhaust flow path P1. The induction fan 161 is a device that generates an airflow by inducing surrounding gas. In this embodiment, the induced draft fan 161 is configured to generate an airflow (an airflow from bottom to top in FIG. 2) that causes gas to be exhausted from the outlet of the exhaust flow path P1 (the top of the chimney 150). The output of the induced draft fan 161 is controlled by the control unit 190. Details of the control will be described later.

[0021] <Basic operation and behavior of furnace equipment> First, the material to be carbonized W is charged from the top of the furnace body 110 from which the lid portion 130 has been removed. The charged material to be carbonized W is piled up on the floor 140 and stored in the upper space S1. The material to be carbonized W is added, for example, to a height of several tens of centimeters to several meters from the bed 140 (until the layer thickness is several tens of centimeters to several meters).

[0022] Next, the burners 183 are inserted through the insertion openings 122b to ignite the material W to be carburized near the bed 140. When the material to be carbonized W starts to burn, the heat generated by the combustion is transferred to the exhaust passage P1 formed in the chimney 150 via the lower space S2. Then, due to the chimney effect, an airflow is automatically generated that exhausts gas from the outlet of the exhaust flow path P1 (the top of the chimney 150). Furthermore, due to the influence of this airflow, an airflow is automatically generated that flows in the following order: outside the furnace body 110, the intake opening 122a of the vessel part 120, the upper space S1, the communication part 141 of the floor 140, the lower space S2, and the inlet of the exhaust flow path P1. In other words, due to the chimney effect, an airflow is automatically generated that flows in the following order: outside the furnace body 110, the intake opening 122a, the upper space S1, the communication part 141, the lower space S2, the inlet of the exhaust flow path P1, and the outlet of the exhaust flow path P1. As a result, the material to be carbonized W is combusted and carbonized by the downflow of naturally aspirated combustion air. Furthermore, the combustion exhaust gas generated during carbonization is discharged to the outside of the furnace body 110 via the chimney 150 (exhaust flow path P1). Here, the combustion exhaust gas is a gas generated by the reaction of pyrolysis gases and the like with oxygen (O2), and contains carbon dioxide (CO2).

[0023] However, the optimal flow rate of combustion air for carbonization varies depending on the change in layer thickness that occurs as the carbonization of the stored carbonized material W progresses, the bulk density of the carbonized material W, the surface moisture of the carbonized material W, etc. Therefore, in the furnace equipment 100 according to this embodiment, the induced draft fan 161 is installed in the exhaust passage P1 to adjust the flow rate of the combustion air taken into the upper space S1 from the intake opening 122a. For example, when the layer thickness of the carbonized material W is thick or the bulk density of the carbonized material W is high, the pressure loss when the combustion air passes through the carbonized material W is large, so the output of the induced draft fan 161 is increased to take in an appropriate flow rate of combustion air. Also, for example, when the surface moisture content of the carbonized material W is high, the carbonized material W is difficult to dry, so in order to promote drying, the output of the induced draft fan 161 is increased to take in an appropriate flow rate of combustion air.

[0024] Whether the flow rate of the taken-in combustion air is optimal or not is determined based on, for example, the flow rate of the gas (gas including combustion exhaust gas) discharged from the chimney 150. In this case, a flow meter 191 capable of measuring the flow rate of gas containing combustion exhaust gas is installed, for example, in the exhaust flow path P1. The flow meter 191 is configured to be able to communicate with the control unit 190, and the control unit 190 controls the output of the induced draft fan 161 so that the measurement value of the flow meter 191 approaches a preset target value of the flow rate.

[0025] Furthermore, the opening area of ​​the intake opening 122a of the container 120 may be changed based on the measurement value of the flow meter 191. Specifically, the opening area of ​​the intake opening 122a may be increased when a large amount of combustion air is taken in, and may be decreased when a small amount of combustion air is taken in. The appropriate opening area of ​​the intake opening 122 a is determined by the control unit 190 . The opening area of ​​the intake opening 122a is adjusted by sliding a blocking plate 122c provided at the intake opening 122a, as shown in FIG.

[0026] <<Modifications>> As shown in FIG. 5, the intake opening 122a may be a plurality of holes (through holes) arranged along the front-rear direction. In this case, the opening area of ​​the intake openings 122a is adjusted by changing the number of intake openings 122a that are opened. Alternatively, the opening area of ​​each intake opening 122a may be adjusted individually.

[0027] <Height of furnace body> When the furnace equipment 100 is loaded onto the vehicle 10 and moved, the height dimension of the furnace equipment 100 needs to be set within a range that does not violate regulations (for example, the Road Traffic Act). On the other hand, when the furnace equipment 100 is operated, it is preferable to store a larger amount of material W to be carbide. Therefore, the furnace equipment 100 is configured so that the height of the furnace body 110 and the height of the chimney 150 can be changed. An example of changing the height will be described below.

[0028] <<Example 1 (height of furnace body)>> As shown in FIG. 6, the container 120 has a movable peripheral wall 123 in addition to a peripheral wall 122 . The movable peripheral wall 123 is a wall extending in the vertical direction and configured to fit, for example, on the inner peripheral surface of the peripheral wall 122. In this case, the lid portion 130 is provided on the upper part of the movable peripheral wall 123 so as to close the opening on the upper surface of the movable peripheral wall 123. The movable peripheral wall 123 is configured to be slidable in the up and down direction relative to the peripheral wall 122 . When the movable peripheral wall 123 is positioned downward, the height of the furnace body 110 is low and the volume of the upper space S1 is small. On the other hand, when the movable peripheral wall 123 is positioned upward, the height of the furnace body 110 is high and the volume of the upper space S1 is large.

[0029] The movable peripheral wall 123 has at least one air intake opening 123a. In the case of FIG. 6, the intake openings 123a are rectangular openings extending in the front-rear direction, and are provided in the upper portions of both left and right walls of the movable peripheral wall 123. When the movable peripheral wall 123 is positioned downward, the position of the intake opening 123a of the movable peripheral wall 123 coincides with the position of the intake opening 122a of the peripheral wall 122. In other words, even when the movable peripheral wall 123 is positioned downward, the upper space S1 can be in communication with the outside of the vessel part 120 via the intake opening 123a and the intake opening 122a (i.e., the furnace equipment 100 can be operated). On the other hand, when the movable peripheral wall 123 is positioned in the upper position, the intake opening 122a is covered to prevent the material to be carbonized W stored in the upper space S1 from spilling out through the intake opening 122a of the peripheral wall 122. In the case of Fig. 6, the lower part of the movable peripheral wall 123 is used as the lid, but a separate lid may also be prepared.

[0030] The height of the chimney 150 may be changed in accordance with the sliding of the movable peripheral wall 123.

[0031] <<Example 2 (height of furnace body)>> As shown in FIG. 7, the container 120 has a movable peripheral wall 124 in addition to the peripheral wall 122 . The movable peripheral wall 124 is a wall that extends in the vertical direction, and one end of the movable peripheral wall 124 is connected to the upper end of the peripheral wall 122 by a hinge. When the movable peripheral wall 124 is lowered, the height of the furnace body 110 is low and the volume of the upper space S1 is small. On the other hand, when the movable peripheral wall 123 is raised, the height of the furnace body 110 is high and the volume of the upper space S1 is large. Here, "the movable peripheral wall 124 is lowered" means that the end of the movable peripheral wall 124 on the side where the hinge is not provided is facing downward, and "the movable peripheral wall 124 is raised" means that the end of the movable peripheral wall 124 on the side where the hinge is not provided is facing upward.

[0032] The movable peripheral wall 124 has at least one air intake opening 124a. In the case of FIG. 7, the intake openings 124a are rectangular openings extending in the front-rear direction, and are provided on both left and right walls of the movable peripheral wall 124. When the movable peripheral wall 124 is lowered, the position of the intake opening 124a of the movable peripheral wall 124 coincides with the position of the intake opening 122a of the peripheral wall 122. In other words, even when the movable peripheral wall 124 is lowered, the upper space S1 can be in communication with the outside of the vessel part 120 via the intake openings 123a and 122a (i.e., the furnace equipment 100 can be operated). On the other hand, when the movable peripheral wall 124 is raised, the intake opening 122a is covered so that the material W stored in the upper space S1 does not spill out through the intake opening 122a of the peripheral wall 122.

[0033] The height of the chimney 150 may also be changed in accordance with the position of the movable peripheral wall 124 .

[0034] <Removing the lid> For example, when the material to be carbonized W is put into the container 120, it is necessary to remove the lid 130 and open the opening on the top surface of the container 120. Several embodiments for removing the lid 130 will now be described.

[0035] <<Example 3 (Removing the lid)>> The lid 130 is removed by a crane 184 as shown in FIG.

[0036] <<Example 4 (Removing the lid)>> As shown in Figure 9, the ends of each of the first lid portion 131 and the second lid portion 132 as the lid portion 130 may be connected to the upper end of the peripheral wall 122 by a hinge, and the opening on the top surface of the container portion 120 may be opened by rotating the first lid portion 131 and / or the second lid portion 132 around the hinge.

[0037] <Preheating of combustion air> In order to improve the drying speed and carbonization speed of the material to be carbonized W, the combustion air taken in through the intake opening 122a may be preheated. An embodiment of a configuration capable of preheating combustion air will now be described.

[0038] As shown in FIG. 10, the chimney 150 has a vertical portion 151 and a horizontal portion 152. The vertical portion 151 is a portion extending in the up-down direction along the side surfaces (both side surfaces in the front-rear direction in the case of FIG. 10) of the container portion 120. The exhaust flow path P1 formed in the vertical portion 151 is connected at its lower portion to the lower space S2 and at its upper portion to the exhaust flow path P1 formed in the horizontal portion 152. The horizontal portion 152 is a portion extending in the horizontal direction (front-to-back direction in the case of FIG. 10). One end of the exhaust flow path P1 formed in the horizontal portion 152 is connected to the exhaust flow path P1 formed in one of the vertical portions 151, and the other end is connected to the exhaust flow path P1 formed in the other vertical portion 151. In addition, the middle portion of the exhaust flow path P1 formed in the horizontal portion 152 is connected to the outside of the furnace body 110.

[0039] Furthermore, the furnace equipment 100 is provided with an intake duct 170 having an intake passage formed therein. The intake duct 170 has a plurality of branch ducts 171 connected to the intake openings 122 a , and is configured so that the intake combustion air is distributed to each branch duct 171 . At least a portion of the intake duct 170 is located in the exhaust flow path P1 formed in the chimney 150. In the case of FIG. 10 , the horizontal portion of the intake duct 170 is located in the exhaust flow path P1 formed in the horizontal portion 152 of the chimney 150.

[0040] Since gas with a higher temperature than the intake combustion air flows through the exhaust flow path P1, the combustion air flowing through the intake duct 170 is heated (preheated) by heat exchange with the gas flowing through the exhaust flow path P1.

[0041] <Promotion of ignition by burner> When the burner 183 inserted through the insertion opening 122b is igniting the carbonized material W located near the floor 140, the downflow of combustion air caused by the combustion of the already ignited carbonized material W may cause the flame of the burner 183 to face downward, which may hinder ignition of the carbonized material W.

[0042] Therefore, as shown in FIG. 11, another induction fan (second fan) 162 may be provided at the intake opening 122a of the container part 120. The induced draft fan 162 is configured to generate an airflow that causes gas to be expelled from the intake opening 122a. By operating the induced draft fan 162, an airflow is generated that flows in the following order: outside the furnace body 110, the outlet of the exhaust flow path P1, the inlet of the exhaust flow path P1, the lower space S2, the communication section 141, the upper space S1, and the intake opening 122a. The "outlet" and "inlet" of the exhaust flow path P1 are determined based on the direction of the airflow due to the chimney effect.

[0043] This causes the flame of the burner 183 to be directed toward the material to be carbonized W piled up on the floor 140 above, facilitating ignition of the material to be carbonized W.

[0044] <Basket for storing carbonized materials> As shown in FIG. 12, the furnace facility 100 may include a cage 181 for storing the material W to be carburized. The cage 181 is a container with an open top, and is installed in the upper space S1 of the container section 120. The cage 181 is made of, for example, a wire mesh.

[0045] 13, after carbonization is completed, the carbide can be removed from the furnace body 110 together with the cage 181. The cage 181 is transported by a crane 184, for example.

[0046] <Upper space partition> As shown in FIGS. 14 and 15, the furnace equipment 100 may include at least one partition plate 182. The partition plate 182 is installed in the upper space S1 of the container part 120 and divides the upper space S1 in the horizontal direction. In the case of Fig. 14, the partition plate 182 divides the upper space S1 into two spaces in the front-to-rear direction. In the case of Fig. 15, the partition plate 182 divides the upper space S1 into two spaces in the left-to-right direction. The number and arrangement of the partition plates 182 can be changed as appropriate.

[0047] As a result, even if the amount of material W to be treated is small, a sufficient layer thickness can be maintained by introducing the material W into the partitioned upper space S1, i.e., the upper space S1 with a reduced volume.

[0048] Furthermore, each partitioned section can be regarded as an independent furnace body 110. This allows different types of material W to be charged, the material W to be charged at different times for each section, and the carbide material to be removed at different times for each section.

[0049] According to this embodiment, the following effects are achieved. The induced draft fan 161 is provided in the exhaust flow path P1 and is configured to exhaust gas including combustion exhaust gas from the exhaust flow path P1 to the outside of the furnace body 110, so that the flow rate of the exhausted gas can be changed according to changes in the layer thickness that accompany the progress of carbonization of the stored material to be carbonized W, the bulk density of the material to be carbonized W, the surface moisture of the material to be carbonized W, etc. Furthermore, when the flow rate of the exhausted gas is changed, the flow rate of the combustion air taken in from the intake opening 122a also changes. In other words, by providing the induction fan 161, it becomes possible to adjust the flow rate of combustion air taken in from the intake opening 122a according to changes in layer thickness that accompany the progress of carbonization of the stored carbonized material W, the bulk density of the carbonized material W, the surface moisture of the carbonized material W, etc.

[0050] Furthermore, the control unit 190 controls the output of the induced draft fan 161 based on the measurement value of the flow meter 191, and therefore can manage the output of the induced draft fan 161 based on the flow rate of the exhaust combustion gas being discharged.

[0051] Furthermore, the control unit 190 controls the opening area of ​​the intake opening 122a based on the measurement value of the flow meter 191, so that the flow rate of the combustion air taken in through the intake opening 122a can be adjusted more efficiently.

[0052] Furthermore, since the furnace body 110 is configured so that its dimension in the height direction is variable, for example, when the furnace equipment 100 is loaded onto the vehicle 10 and moved, the height dimension of the furnace body 110 can be set to a dimension that does not violate regulations (the furnace body 110 can be lowered). On the other hand, when the furnace equipment 100 is operated, the furnace body 110 can be raised to increase the volume of the upper space S1 where the material to be carbonized W is stored and carbonized.

[0053] Furthermore, the chimney 150 is configured so that its height dimension is variable, and therefore the height dimension of the chimney 150 can be set to match the changing height dimension of the furnace body 110.

[0054] Moreover, since the lid portion 130 is configured to be able to be opened and closed, the material to be carbonized W can be easily supplied to the upper space S1.

[0055] Furthermore, the chimney 150 and the intake duct 170 are configured to enable heat exchange between the gas flowing through the exhaust passage P1 and the gas flowing through the intake passage, so that the combustion air (combustion air taken in from outside) flowing through the intake passage and led to the intake opening 122a can be heated by the high-temperature gas flowing through the exhaust passage P1. This improves the drying speed and carbonization speed of the material to be carbonized W and also leads to a reduction in energy loss.

[0056] Furthermore, the induced draft fan 162 is provided in the intake opening 122a and configured to exhaust gas from the upper space S1 to the outside of the furnace body 110, so that it can generate a flow of gas that is exhausted from the lower space S2 through the communication part 141 and the upper space S1 and from the intake opening 122a. This makes it easier for the flame of the ignition burner 183 inserted into the lower space S2 from the insertion opening 122b to transfer to the material to be carbonized W stored in the upper space S1.

[0057] Furthermore, since the basket 181 is installed in the upper space S1 and stores the material to be carbonized W, the material to be carbonized can be removed from the furnace body 110 together with the basket 181 after carbonization is completed.

[0058] Furthermore, since the partition plate 182 divides the upper space S1 horizontally into multiple spaces, even if the amount of material W to be processed is small, a sufficient layer thickness can be maintained by introducing the material W into the partitioned portion of the upper space S1, i.e., the portion of the upper space S1 with a reduced volume. Furthermore, each partitioned section can be regarded as an independent furnace body 110. This allows different types of material W to be charged, the material W to be charged at different times for each section, and the carbide material to be removed at different times for each section.

[0059] Furthermore, since the furnace equipment 100 is provided with a connection portion that is used to connect to the vehicle 10 when the furnace equipment 100 is mounted on the vehicle 10 .
