[0009] According to this disclosure, an output device, an output method, and a program can be provided that can output information when replacing fossil fuel-derived coke with biomass coke. [Brief explanation of the drawing]

[0010] [Figure 1] This is a schematic diagram showing a waste treatment facility to which the output device disclosed herein is applied. [Figure 2] This is a schematic block diagram showing a specific example of the functional configuration of an information output device. [Figure 3] This is a flowchart illustrating the output method according to the embodiment. [Figure 4] This figure shows an example of the output result produced by the information output device. [Modes for carrying out the invention]

[0011] Hereinafter, an output device, output method, and program according to one embodiment of this disclosure will be described in detail with reference to the drawings.

[0012] [Melting Furnace 1] Figure 1 is a schematic diagram showing a waste treatment facility (e.g., a melting furnace) to which the output device of the present disclosure is applied. The shaft furnace type high-temperature gasification melting furnace 1 (hereinafter referred to as "melting furnace 1") burns coke in the lower part of the furnace to form a high-temperature coke bed layer, ensuring stable melting while promoting the thermal decomposition and gasification of waste. The waste is charged into the melting furnace 1 from the top and dried, thermally decomposed, and gasified by air supplied from the grate located in the horizontal lower part of the melting furnace 1, and the waste carbonization residue moves to the bottom of the melting furnace 1. The coke and limestone required to melt this waste carbonization residue are charged in from directly above the bottom. The limestone is used as a basicity adjuster for the slag and has the function of improving its fluidity. At the bottom of the melting furnace 1, oxygen-enriched air supplied from the tuyeres (air blower nozzles) reacts with the coke to form a high-temperature coke bed layer, which is then used to melt the waste carbonization residue. The molten material is discharged from the bottom outlet into a cooling device and rapidly cooled, becoming granular slag and metal. These are then separated and recovered using a magnetic separator, and each is recycled as a resource. Furthermore, waste treatment facilities are not limited to melting furnaces. For example, a waste treatment facility may also be a stoker furnace.

[0013] Melting furnace 1 can process a variety of waste, including general waste, incineration ash, excavated waste, and disaster waste. By using melting furnace 1, the amount of waste to be sent to final disposal can be reduced, and high-quality, usable slag and metal can be produced.

[0014] In light of the recent social demands for decarbonization, the waste and resource recycling sector is also required to reduce carbon dioxide (CO2) emissions. Specifically, it is necessary to reduce carbon dioxide emissions caused by coke derived from fossil fuels such as coal.

[0015] In order to reduce carbon dioxide emissions, efforts are underway to apply biomass coke B, a carbon-neutral material using plant-derived raw materials, to the melting furnace 1 instead of fossil fuel-derived coke C. That is, it is required to shift the fossil fuel-derived coke C (coal raw material) normally used in the melting furnace 1 to the carbonaceous material (biomass coke B) of the biomass raw material. In the present disclosure, biomass refers to biological resources other than fossil fuels. Examples of biomass include thinned wood, pruning branches, waste wood, bark chips, construction waste chips, other woods, bamboo, grass, coconut shells, biomass residues generated in the palm oil industry, vegetables, fruits, food residues, waste mushroom beds, sludge, and other wastes. Biomass may be woody biomass such as thinned wood, pruning branches, waste wood, bark chips, and other woods. Also, since the particle strength of biomass carbide can be improved, coconut shells are preferable as biomass. Examples of the coconut that is the raw material of the coconut shell include palm coconut (oil palm), giant coconut, and coconut palm. The carbonaceous material (biomass coke B) of the biomass raw material can be obtained by carbonizing such biomass. However, since the amount of biomass coke B is likely to increase when substituting it for fossil fuel-derived coke C, it is necessary to know the usage multiple. That is, when substituting biomass coke B for fossil fuel-derived coke C, it is necessary to know the exact unit consumption of biomass coke B. Knowing the exact unit consumption of biomass coke B includes, for example, quantitatively evaluating the increase or decrease ratio of the unit consumption when substituting biomass coke B for fossil fuel-derived coke C. Therefore, in the present embodiment, the information output device 10 is used to calculate and output the amount of biomass coke B that is the same as the amount of a predetermined amount of fossil fuel-derived coke C and the slag temperature (hereinafter also referred to as the melt temperature). Note that the unit consumption indicates the fuel required to process 1 ton of waste.

[0016] 〔Information output device 10〕 FIG. 2 is a schematic block diagram showing a specific example of the functional configuration of the information output device. As shown in FIG. 2, the information output device 10 (output device) is configured using an information device such as a smartphone, a tablet, a personal computer, a dedicated device, a server device, or the like. The information output device 10 includes a communication unit 11, an input unit 12, an output unit 13, a storage unit 15, and a control unit 16.

[0017] As shown in FIG. 2, the communication unit 11 is a communication device. The communication unit 11 may be configured as, for example, a network interface. The communication unit 11 performs data communication with other devices via a network according to the control of the control unit 16. The communication unit 11 may be a device that performs wireless communication or a device that performs wired communication.

[0018] As shown in FIG. 2, the input unit 12 is configured using an existing input device such as a keyboard, a pointing device (mouse, tablet, etc.), a button, a touch panel, or the like. The input unit 12 is operated by the user when inputting a user instruction to the information output device 10. The input unit 12 may be an interface for connecting an input device to the information output device 10. In this case, the input unit 12 inputs an input signal generated in response to a user input in the input device to the information output device 10. The input unit 12 may be configured using a microphone and a voice recognition device. In this case, the input unit 12 acquires an acoustic signal generated by the user's speech, recognizes the words spoken by the user, and inputs the string information of the recognition result to the information output device 10. The voice recognition processing may be executed by the control unit 16. The input unit 12 may be configured in any manner as long as it can input a user instruction to the information output device 10.

[0019] As shown in FIG. 2, the output unit 13 outputs various information in a form recognizable by the user. The output unit 13 may be, for example, a printer. The output unit 13 may also be an interface for connecting a printer to the information output device 10. In this case, the output unit 13 generates a print signal for printing print data and outputs the print signal to the printer connected to the output unit 13 itself. The output unit 13 may be a device that outputs sound, such as a speaker. The output unit 13 may also be an interface for connecting an audio output device, such as a speaker or headphones, to the information output device 10. In this case, the output unit 13 generates an audio signal for playing audio data and outputs the audio signal to the audio output device connected to it.

[0020] As shown in Figure 2, the output unit 13 may be an image display device such as a liquid crystal display or an organic EL (Electro Luminescence) display. The output unit 13 may also be an interface for connecting an image display device to the information output device 10. In this case, the output unit 13 generates a video signal for displaying image data and outputs the video signal to the image display device connected to it. The output unit 13 may be configured as a touch panel integrated with the input unit 12.

[0021] As shown in Figure 2, the storage unit 15 is configured using a storage device such as a magnetic hard disk drive or a semiconductor storage device. The storage unit 15 stores data used by the control unit 16. The storage unit 15 stores data necessary for the control unit 16 to perform processing. The storage unit 15 stores the calibration curve D, which will be described later, and the substitution ratios for each biomass coke B.

[0022] As shown in Figure 2, the control unit 16 is composed of a processor such as a CPU (Central Processing Unit) and memory (main memory). The control unit 16 functions as a memory control means 21, a designation means 22, a calculation means 23, and an output means 24 when the processor executes a program.

[0023] All or part of the functions of the control unit 16 may be implemented using hardware such as an ASIC (Application Specific Integrated Circuit), a PLD (Programmable Logic Device), or an FPGA (Field Programmable Gate Array). The above program may be recorded on a computer-readable recording medium. Computer-readable recording media include, for example, portable media such as flexible disks, magneto-optical disks, ROMs, CD-ROMs, and semiconductor storage devices (e.g., SSDs: Solid State Drives), as well as storage devices such as hard disks and semiconductor storage devices built into computer systems. The above program may be transmitted via a telecommunications line.

[0024] The control unit 16 may, for example, execute an application (program) installed on its own device (information output device 10). A specific example of such an application (program) is an application (program) for implementing the output method described later. In other words, there is an application (program) that makes the information output device 10 (computer) function as the output device of this disclosure. Another concrete example of an application (program) is a web browser application (program). Such an application (program) may be pre-installed on the information output device 10, or it may be downloaded each time a determination process is executed. For example, if it is implemented as a web browser application (program), the information output device 10 may download and execute the application (program) from a device specified by the web server (for example, the web server itself or another server) when the information output device 10 connects to a specific web server. The control unit 16 operates according to the application (program) that is currently running.

[0025] As shown in Figure 2, the memory control means 21 causes the memory unit 15 of the information output device 10 to store various types of information. For example, the memory control means 21 stores various applications (programs), calibration curve D, and substitution ratios for each type of biomass coke B in the memory unit 15.

[0026] As shown in Figure 2, the designation means 22 specifies a predetermined amount of fossil raw material-derived coke C based on information entered by the user from the input unit 12. The designation means 22 also specifies the type of biomass coke B based on information entered by the user from the input unit 12.

[0027] As shown in Figure 2, the calculation means 23 calculates the amount (quantity information) of biomass coke B that has the same slag temperature as the predetermined amount of fossil raw material-derived coke C, according to the type of biomass coke B specified by the designation means 22 and the predetermined amount of fossil raw material-derived coke C specified by the designation means 22. This amount may correspond to the weight of biomass coke B.

[0028] As shown in Figure 2, the output means 24 outputs various information from the output unit 13 of the information output device 10. The output means 24 outputs the amount information of biomass coke B obtained by the calculation means 23 from the output unit 13. The specific output information from the output means 24 will be described later.

[0029] As shown in Figure 2, the output means 24 causes the output unit 13 of the information output device 10 to display various information. The output means 24 outputs quantity information corresponding to the amount of biomass coke B from the output unit 13. The output unit 13 also outputs an image. The specific display screen (output information) by the output means 24 will be described later.

[0030] [Output Method] Figure 3 is a flowchart illustrating the output method according to the embodiment. An output method according to one embodiment of this disclosure includes a calibration curve creation and storage step S1, a designation step S2, a calculation step S3, and an output step S4. Each of the following steps is performed by the control unit 16 (storage control means 21, designation means 22, calculation means 23, output means 24) based on the information stored in the storage unit 15, for example. However, the execution is not limited to the control unit 16 and may be performed by a human.

[0031] (Calibration curve creation and memory step S1) In calibration curve creation and memory step S1, first, a basic calibration curve D is determined in order to calculate the amount of biomass coke B, which has the same slag temperature as fossil raw material coke C. Calibration curve D is a line drawn using the slag temperature corresponding to a predetermined amount input by the input unit 12. First, operation is performed in the melting furnace 1 using fossil raw material-derived coke C, and the coke unit rate of fossil raw material-derived coke C is fixed and the molten material temperature is recorded. There are multiple coke unit rates for fossil raw material-derived coke C. For example, it is preferable that the coke unit rate for fossil raw material-derived coke C is 3 or more conditions (for example, including 3 conditions such as fixed carbon unit rates of 15 [kg / ton of waste], 20 [kg / ton of waste], and 25 [kg / ton of waste]). Alternatively, for example, the coke unit rate for fossil raw material-derived coke C may be 2 conditions (for example, including 2 conditions such as fixed carbon unit rates of 15 [kg / ton of waste], 20 [kg / ton of waste], and 25 [kg / ton of waste]). For fossil raw material-derived coke C, operation is performed in the melting furnace 1 with, for example, 3 coke unit rates, and the molten material temperature is recorded for each condition. Then, for example, three coke intensity values ​​are converted to fixed carbon intensity values, and a calibration curve D for molten temperature is created using these fixed carbon intensity values ​​as variables (see Figure 4). In other words, a linear function is determined to calculate the molten temperature from the fixed carbon intensity values.

[0032] Next, we will conduct replacement tests with biomass coke B, etc. Prior to the substitution test, a component analysis of Biomass Coke B will be conducted. There are several types of Biomass Coke B. Biomass Coke B can be manufactured using waste biomass, unused biomass, resource crops, etc. Biomass Coke B may also be made from recycled sawdust generated during wood processing. Biomass coke B may contain an inorganic binder. The inorganic binder is an inorganic substance that has the function of binding together the particles of biomass char. In a dry state, the CaO content of the inorganic binder is 50% by mass or more of the total mass of the inorganic binder. In a dry state, the CaO content of the inorganic binder may be 55% by mass or more, or 60% by mass or more. Such an inorganic binder can reduce the melting point of the slag when used in a gasification melting furnace or a cupola furnace. In these facilities, limestone may be used as an auxiliary material, but some or all of the limestone can be replaced by CaO from the inorganic binder. Here, "dry state" refers to a state in which the object is dried at a temperature of 120 to 200 [°C] until it reaches a constant mass, and the free water contained inside the object is removed. The inorganic binder may contain Portland cement as defined in JIS R 5210:2009. Examples of Portland cement include ordinary Portland cement, rapid-hardening Portland cement, ultra-rapid-hardening Portland cement, moderate-heat Portland cement, low-heat Portland cement, and sulfate-resistant Portland cement. The CaO content in Portland cement can be measured in accordance with the "Chemical Analysis Method for Cement" in JIS R 5202:2010. Inorganic binders may contain components other than Portland cement (other inorganic substances). Inorganic binders do not contain water (except for hydration water and crystal water). Other inorganic substances are not particularly limited as long as they are inorganic, and examples include clay and sodium silicate. Examples of clay include bentonite (montmorillonite) and kaolin. If the inorganic binder contains multiple types of components, it is sufficient that the total CaO content of the inorganic binder is within the above range. If the inorganic binder contains components other than Portland cement, it can be measured in accordance with the second edition of the Inorganic Element Measurement Method published by the Ministry of the Environment. Biomass coke B may have different post-heating tensile strengths. For example, the post-heating tensile strength of biomass coke B may preferably be 1000 [N] or more. More preferably, the post-heating tensile strength of biomass coke B may be 2500 [N] or more. Here, post-heating tensile strength refers to an index used to evaluate how well a material can withstand tensile force after being heated to 1000 [°C] in an air atmosphere and exposed to a high-temperature, oxidizing environment. Therefore, a component analysis is performed on these biomass cokes B in advance, and the fixed carbon intensity (hereinafter referred to as BFCR) contained in each biomass coke B is calculated from the results of this component analysis and the actual amount of biomass coke B fed into the melting furnace 1. In other words, the quantity information corresponding to each of the multiple types of biomass coke is calculated. BFCR is calculated by multiplying the fixed carbon ratio {kg-FC / kg-biomass coke} contained in biomass coke B, based on the results of component analysis, by the actual amount of biomass coke used {kg-biomass coke / tons of waste}.

[0033] In the replacement test with biomass coke B, multiple biomass coke B types available in melting furnace 1 are used. That is, operation (replacement test) is carried out in melting furnace 1 using each biomass coke B type. At this time, the coke intensity of biomass coke B is fixed and the molten material temperature is recorded. The coke intensity of biomass coke B may be one type. The coke intensity of biomass coke B may be multiple types.

[0034] Next, using the molten temperature of each biomass coke B and the calibration curve D described above, we calculate the fixed carbon intensity (FCR) of fossil-derived coke C that is equal to the molten temperature during operation using each of the biomass coke B. Then, the substitution ratio is determined from BFCR and FCR. That is, the value obtained by dividing BFCR by FCR is the substitution ratio. Replacement magnification=BFCR / FCR The substitution ratio is determined for each of the multiple biomass coke B types. For example, the substitution ratio for biomass coke P, which is one type of biomass coke B, is calculated to be 1.15. The substitution ratio for biomass coke P includes the ratio of a predetermined amount to the amount corresponding to the quantity information. Furthermore, the substitution ratio for biomass coke P includes the ratio of a predetermined amount of fixed carbon intensity to the amount of fixed carbon intensity corresponding to the quantity information.

[0035] Calibration curve D and the substitution ratio of each biomass coke B are stored in the storage unit 15 by the memory control means 21. By determining calibration curve D and the substitution ratio of each biomass coke B, it becomes possible to quantitatively evaluate the fixed carbon molten material heating capacity of biomass coke B. In other words, it becomes possible to quantitatively grasp the increase or decrease in the amount of biomass coke B used when replacing fossil raw material-derived coke C with biomass coke B. This makes it possible, for example, to calculate the running cost of each biomass coke B.

[0036] (Specified step S2) In the specified step S2, a predetermined amount of fossil raw material-derived coke C is input from the input unit 12. In the first example, for instance, "40.8" is entered from the input unit 12 as the predetermined quantity [kg / TR]. Furthermore, the biomass coke B to be used in the melting furnace 1, etc., is specified from the input unit 12. For example, "Biomass Coke P" is entered from the input unit 12 as the type of biomass coke B. Alternatively, "Biomass Coke Q" or "Biomass Coke R" may also be entered from the input unit 12 as the type of biomass coke B.

[0037] In the second example, for instance, "44.0" is input from the input unit 12 as a predetermined quantity [kg / TR]. Furthermore, the biomass coke B to be used in the melting furnace 1, etc., is specified from the input unit 12. For example, "biomass coke P" is input from the input unit 12 as the type of biomass coke B.

[0038] (Calculation step S3) In calculation step S3, the amount of biomass coke B that has the same slag temperature as the predetermined amount of fossil raw material-derived coke C is calculated based on the predetermined amount of biomass coke B specified in designation step S2 and the substitution ratio. In other words, the amount of biomass coke B that has the same slag temperature as fossil raw material-derived coke C is calculated by multiplying the substitution ratio by the predetermined amount. In the first example described above, for instance, if the substitution ratio of biomass coke B is "1.15", then the amount of biomass coke B with the same slag temperature as fossil raw material-derived coke C is: 40.8 × 1.15 = 46.9 [kg / TR] This is the result.

[0039] In other words, when the fixed oxygen intensity of fossil-derived coke C is 40.8 [kg / TR], the slag temperature is 1404°C, and the fixed carbon intensity of biomass coke B that achieves this slag temperature of 1404°C is 46.9 [kg / TR]. This is the result.

[0040] In the second example described above, for example, if the substitution ratio of biomass coke B is "1.05", the amount of biomass coke B that has the same slag temperature as fossil raw material-derived coke C is: 44.0 × 1.05 = 46.2 [kg / TR] This is the result. In other words, when the fixed oxygen intensity of fossil-derived coke C is 44.0 [kg / TR], the slag temperature is 1416°C, and the fixed carbon intensity of biomass coke B that achieves this slag temperature of 1416°C is 46.2 [kg / TR]. This is the result.

[0041] (Output step S4) Figure 4 shows an example of a user interface output by the information output device 10. In output step S4, the amount (quantity information) of biomass coke B obtained in calculation step S3 is output to the output unit 13 of the information output device 10. For example, in output step S4, the output unit 13 displays the amount (quantity information) corresponding to each of the multiple types of biomass coke B obtained in calculation step S3. In the first example described above, for example, an image (text, characters) showing 40.8 [kg / TR] of fossil raw material-derived coke C and 46.9 [kg / TR] of biomass coke B is displayed. In the second example described above, for example, an image (text, characters) showing 44.0 [kg / TR] of fossil raw material-derived coke C and 46.2 [kg / TR] of biomass coke B is displayed. In another example, in output step S4, the output unit 13 outputs the amount (quantity information) corresponding to each of the multiple types of biomass coke B obtained in calculation step S3. In other words, the quantity information includes the fixed carbon intensity of a predetermined amount (fossil fuel-derived coke C) and the fixed carbon intensity of the corresponding amount (biomass coke B). Furthermore, the quantity information is output based on the slag temperature corresponding to a predetermined amount of fossil fuel-derived coke and the slag temperature corresponding to biomass coke.

[0042] As shown in Figure 4, the output result G from the information output device 10 displays a graph with the fixed carbon intensity [kg / TR] on the horizontal axis and the molten material temperature [°C] on the vertical axis. The output result G also displays a calibration curve D. In other words, the quantitative information shows both the slag temperature and the amount of fixed carbon contained in the biomass coke. Furthermore, the output result G may also display the recorded information for fossil fuel-derived coke C and biomass coke B in the calibration curve creation and storage step S1. The output result G displays the quantity (quantity information) of biomass coke B as 46.9 [kg / TR]. In addition to this text information, the quantity (quantity information) of biomass coke B may be plotted on a graph for visualization. That is, both the calibration curve D and the quantity information are output. This allows for a quantitative assessment of the increase or decrease in biomass coke usage when replacing fossil-derived coke C with biomass coke B. Consequently, it becomes possible to calculate the running costs of biomass coke.

[0043] Finally, in step S5, you select whether or not to repeat the output method. If you also want to calculate the quantity (quantity information) for other biomass coke B, return to the specified step S2 and repeat the calculation step S3 and other processes. On the other hand, once the calculation and output of the quantity (quantity information) for the desired biomass coke B is complete, the output method is terminated.

[0044] As described above, the output device, output method, and program according to this embodiment can output information when fossil fuel-derived coke C is replaced with biomass coke B. This allows the user to quantitatively understand the amount of biomass coke B used when replacing fossil fuel-derived coke C with biomass coke B.

[0045] The technical scope of this disclosure is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of this disclosure.

[0046] For example, in the above embodiment, the information output device 10 is configured as a single device, but it may be configured as separate devices. For example, the information output device 10 may be implemented using multiple information processing devices. For example, the information output device 10 may be implemented using a device such as a cloud. For example, in the information output device 10, the storage unit and the control unit may be implemented in different information processing devices. For example, the control unit of the information output device 10 may be distributed and implemented in multiple information processing devices.

[0047] The communication unit 11, input unit 12, output unit 13, storage unit 15, and control unit 16 may be omitted. The memory control means 21, the designation means 22, the calculation means 23, and the output means 24 may be omitted.

[0048] The quantitative information does not necessarily have to include the ratio of a predetermined quantity to the quantity corresponding to that quantitative information. The ratio does not necessarily have to include the ratio of a predetermined amount of fixed carbon intensity to the amount of fixed carbon intensity corresponding to the quantity information. The quantity information does not necessarily have to include a predetermined amount of fixed carbon intensity and a quantity of fixed carbon intensity corresponding to the quantity information. The output means 24 does not need to output quantity information based on the slag temperature corresponding to a predetermined amount of fossil raw material-derived coke and the slag temperature corresponding to biomass coke.

[0049] The output means 24 does not necessarily have to output quantity information based on a calibration curve D drawn using the slag temperature corresponding to a predetermined amount input by the input unit 12. Furthermore, the output means 24 does not necessarily have to use the calibration curve D. The output means 24 does not have to output both the calibration curve D and the quantity information. For example, the output means 24 may output only the calibration curve D. The output means 24 may output only the quantity information. The output means 24 does not have to output quantity information in accordance with a predetermined amount specified by the designation means 22. The quantitative information does not necessarily have to show both the slag temperature and the amount of fixed carbon contained in the biomass coke. For example, the quantitative information may only show the slag temperature. The quantitative information may only show the amount of fixed carbon contained in the biomass coke. Fossil fuel-derived coke and biomass coke do not necessarily have to be used in melting furnaces. For example, fossil fuel-derived coke alone may be used in melting furnaces, or biomass coke alone may be used in melting furnaces. The biomass coke does not need to be of multiple types; it can be of just one type. The output means 24 does not have to output quantity information corresponding to each of the multiple types of biomass coke. For example, the output means 24 may output quantity information corresponding to only one type of biomass coke. The quantity information does not need to correspond to weight.

[0050] Furthermore, it is possible to replace the components in the above embodiments with well-known components as appropriate, without departing from the spirit of this disclosure, and the above-described modifications may be combined as appropriate.
