Description

This disclosure relates to furnace equipment such as carbonization furnaces and reactors.

Furnace equipment equipped with carbonization furnaces, reactors, etc. includes so-called continuous furnace equipment, which continuously or intermittently (interrupted midway through) input biomass raw materials and continuously or intermittently discharges biochar or biofuel as a product (Patent Document 1). Furnace equipment also includes so-called batch furnace equipment, which repeats batch processing, with one batch consisting of the cycle from input of biomass raw materials to discharge of biochar or biofuel as a product (Patent Document 2).

Japanese Patent Application Publication No. 11-278822 Japanese Patent Application Laid-Open No. 2018-21173

Continuous furnace equipment generally tends to be larger than batch furnace equipment. Therefore, when installing a continuous furnace equipment in a space-constrained location (for example, when loading/mounting it on a vehicle) and when a large amount of raw material is to be processed with the continuous furnace equipment, it is necessary to input as much raw material as possible into the space that the furnace equipment can occupy.
However, if a large amount of raw materials is put into a limited space, the raw materials will pile up excessively high inside the furnace equipment, making the raw materials themselves dense and hindering the supply of heat and air to the raw materials.

This disclosure was made in light of these circumstances, and aims to provide furnace equipment with a structure that can prevent items from piling up high on the conveying device and that can be easily made compact while still ensuring the overall conveying distance.

In order to solve the above problems, the furnace equipment of the present disclosure employs the following measures.
A furnace facility according to one embodiment of the present disclosure comprises a plurality of conveying devices that convey at least one of a material to be carbide and a carbide as a transported object, and a container that houses the plurality of conveying devices, wherein the plurality of conveying devices are arranged at intervals in the vertical direction, the transport directions of adjacent conveying devices in the vertical direction are opposite, and the transported object transported by the upper of the adjacent conveying devices in the vertical direction falls at a position between the front end and rear end of the lower conveying device in the transport direction.

This disclosure makes it possible to prevent transported materials from piling up high, and provides furnace equipment with a structure that is easy to make compact while still ensuring the overall transport distance.

FIG. 1 is a perspective view of a furnace facility according to a first embodiment of the present disclosure. FIG. 1 is a side view of a furnace facility according to a first embodiment of the present disclosure. FIG. 10 is a side view of a furnace installation according to a second embodiment of the present disclosure. 1 is a side view showing a furnace facility according to a first embodiment or a second embodiment of the present disclosure mounted on a vehicle. FIG.

[First embodiment]
Hereinafter, a furnace facility according to a first embodiment of the present disclosure will be described with reference to FIGS. 1 and 2. FIG.

<Basic structure of furnace equipment>
The furnace equipment 100 according to one embodiment of the present disclosure is a carbonization furnace equipment/reactor equipment that uses a material to be carbonized W1, such as woody biomass, as a raw material to produce a carbonized material W2, such as biochar or biofuel, as a product.
Hereinafter, the furnace facility 100 according to the first embodiment of the present disclosure will be described using the furnace facility 100 as a carbonization furnace facility as an example.

As shown in FIGS. 1 and 2, the furnace facility 100 includes, for example, a drying chamber 111, a carbonization furnace 112, and a plurality of conveyors (transport devices) 130.
The furnace facility 100 may also include a control unit 170 .

The control unit 170 is a device that performs the control necessary for the operation of the furnace equipment 100, such as controlling each piece of equipment (each conveying device (including a drive unit), each measuring unit, and each analyzing unit) that the furnace equipment 100 is equipped with, processing information obtained from each piece of equipment, and relaying the transmission and reception of signals between each piece of equipment.
The control unit 170 (controller) includes, for example, a CPU (Central Processing Unit: processor), a main memory, a secondary storage, etc. Furthermore, the control unit 170 may include a communication unit for transmitting and receiving information to and from other devices.
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 execution programs of the CPU and writing processing data by the execution programs.
The 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 the form of a program in a secondary storage device, 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.

The furnace equipment 100 is a continuous carbonization furnace equipment in which the drying chamber 111 and the carbonization furnace 112 are integrally installed in the same space.

The drying chamber 111 is a chamber in which the material to be carbonized W1 supplied from the outside is dried before entering the carbonization furnace 112.
The carbonization furnace 112 is a furnace that produces a carbide W2 by carbonizing an object to be carbonized W1 through combustion in an oxygen-deficient environment.

The drying chamber 111 and carbonization furnace 112 are defined by the container 101. In other words, the container 101 serves as both the drying chamber 111 and the carbonization furnace 112.

The container 101 has a substantially rectangular parallelepiped shape and has a space formed therein.
At this time, inside the container 101, the drying chamber 111 is located at the upper part and the carbonization furnace 112 is located at the lower part.
However, the drying chamber 111 and the carbonization furnace 112 are not clearly separated by a fixed boundary. Inside the container 101, the processes from drying to carbonization of the material to be carbonized W1 (i.e., from drying the material to be carbonized W1 to producing the carbonized material W2) need only be carried out continuously from top to bottom.

The plurality of conveyors 130 are housed in the container 101 .
The plurality of conveyors 130 include, for example, a conveyor 130a, a conveyor 130b, a conveyor 130c, a conveyor 130d, and a conveyor 130e.
Hereinafter, when it is necessary to distinguish between the conveyors 130, the reference numerals 130a to 130e will be used. When it is not necessary to distinguish between the conveyors 130, the reference numeral 130 will be used.
The number of conveyors 130 can be changed as appropriate.

Each conveyor 130 is a device on which an object to be transported (at least one of the object to be carbonized W1 and the carbonized object W2) is placed and which transports the object.
Each conveyor 130 is driven by a drive unit (not shown) and is configured to be able to change the conveying speed. In addition, the conveyors 130a, 130b, 130c, 130d, and 130e are configured to be able to change the conveying speed individually.
Each conveyor 130 has a front end 131 and a rear end 132 in the conveying direction. The front end 131 is the end toward which the conveyed object moves, and the rear end 132 is the end opposite the front end 131.

The conveyors 130 are arranged vertically inside the container 101 at intervals from one another.
In this embodiment, conveyors 130a, 130b, 130c, 130d, and 130e are arranged from top to bottom at intervals from one another.

The conveying directions of the conveyors 130 adjacent to each other in the vertical direction are opposite to each other.
In this embodiment, the conveying direction of the conveyors 130a, 130c, and 130e is from the rear of the container 101 to the front, and the conveying direction of the conveyors 130b and 130d is from the front of the container 101 to the rear.
In this embodiment, the front and rear of the container 101 do not necessarily coincide with the front and rear of the container 101 in the conveying direction of the conveyors 130b and 130d.

Of the conveyors 130 adjacent to each other in the vertical direction, the front end 131 of the upper conveyor 130 is positioned between the front end 131 and rear end 132 of the lower conveyor 130 in the direction along the conveying direction of the lower conveyor 130 (the front-to-back direction of the container 101, the left-to-right direction in Figure 2).
As a result, the object conveyed by the upper conveyor 130 falls to a position between the front end 131 and the rear end 132 of the lower conveyor 130.

Here, when the position of the front end 131 of the lower conveyor 130 is 100% and the position of the rear end 132 is 0%, the front end 131 of the upper conveyor 130 should be located in the range of 0% to 50% of the lower conveyor 130, preferably in the range of 0% to 25%, and more preferably in the range of 0% to 10%.
This allows the transported objects to be dropped from the upper conveyor 130 to a position close to the rear end 132 of the lower conveyor 130, making it possible to fully utilize the length of each conveyor 130 in the transport direction to transport the objects, making it easier to ensure the overall transport distance. This leads to efficiently ensuring the time required for drying and carbonization.

By installing each conveyor in this manner, it is possible to prevent transported materials from piling up high on each conveyor 130, and it is possible to reduce the size of each conveyor 130 in the transport direction while maintaining the overall transport distance, thereby making the furnace equipment 100 more compact.

The conveyor 130 may be configured to transport an object, and the specific form of the conveyor 130 is not particularly limited.
Furthermore, the front end 131 of the upper conveyor 130 does not have to be positioned between the front end 131 and the rear end 132 of the lower conveyor 130 in the direction along the conveying direction of the lower conveyor 130 (the front-to-rear direction of the container 101, the left-to-right direction in FIG. 2 ). For example, the front end 131 of the upper conveyor 130 may be positioned behind the rear end 132 of the lower conveyor 130, and a chute may be installed at the drop point of the transported objects transported by the upper conveyor 130, so that the dropped transported objects are guided by the chute to the transport surface of the lower conveyor 130 (for example, a position between the front end 131 and the rear end 132). Even with this method, the transported objects transported by the upper conveyor 130 will end up dropping at a position between the front end 131 and the rear end 132 of the lower conveyor 130.

A raw material input section 141 is provided at the top of the vessel 101 .
The raw material input section 141 is a device that inputs the material to be carbonized W1 from the outside of the container 101 into the inside of the container 101 .
The lower end of the raw material input section 141 is an opening through which the carbonized material W1 is discharged, and is located above the rear end 132 of the conveyor 130a at a point where the input carbonized material W1 will reliably fall onto the conveyor 130a.

The material to be carbonized W1 fed from the raw material feeding section 141 is transported from the vicinity of the rear end 132 of the conveyor 130a to the front end 131, and falls to the vicinity of the rear end 132 of the conveyor 130b.
The transported object that has fallen near the rear end 132 of the conveyor 130b is transported from near the rear end 132 of the conveyor 130b to the front end 131, and then falls near the rear end 132 of the conveyor 130c.
This process of conveying and dropping is repeated until the material reaches the front end 131 of the conveyor 130e. During the conveying process, the material is dried and carbonized.
The material transported to the front end 131 of the conveyor 130e is discharged to the outside of the container 101 as carbide W2 (product).

In this case, it is preferable that each conveyor 130 is disposed so that the front end 131 is lower than the rear end 132. In other words, it is preferable that each conveyor 130 is inclined so that the front end 131 is lower.
This is because by tilting the conveyor 130, the transported materials that fall onto the conveyor 130 collapse toward the front end 131, and as a result, the transported materials on the transport surface of the conveyor 130 are leveled to a roughly uniform layer thickness, allowing the transported materials to be dried and carbonized uniformly.
In the sense that the conveyed objects collapse toward the front end 131, it is preferable that the inclination angle of each conveyor 130 be determined taking into consideration the angle of repose of the conveyed objects.
It should be noted that each conveyor 130 may be configured so that the inclination angle of each conveyor 130 can be changed individually.

<Additional structure of furnace equipment (heat supply)>
The furnace facility 100 may include a plurality of heat supply units 151 .
The heat supply unit 151 is a part configured to supply heat, and examples thereof include a device for supplying heated steam and an electric heater.
The plurality of heat supplying units 151 include, for example, a heat supplying unit 151a, a heat supplying unit 151b, a heat supplying unit 151c, a heat supplying unit 151d, and a heat supplying unit 151e.
Hereinafter, reference numerals 151a to 151e will be used to distinguish between the heat supplying units 151. When no distinction is required between the heat supplying units 151, the reference numeral 151 will be used.

Each heat supplying section 151 is disposed inside the container 101 between adjacent conveyors 130 in the vertical direction and above a conveyor 130a.
In the case of FIG. 2, two heat supplying units 151 are disposed between the vertically adjacent conveyors 130 and above the conveyor 130a.
However, the number and arrangement of the heat supplying units 151 can be changed as appropriate.
The heat quantity supplying unit 151a, the heat quantity supplying unit 151b, the heat quantity supplying unit 151c, the heat quantity supplying unit 151d, and the heat quantity supplying unit 151e can individually change the amount of heat they supply as appropriate.

By providing the heat supplying section 151, the heat required for drying and carbonization can be supplied to the transported object.
Furthermore, by disposing the heat supplying section 151 between the vertically adjacent conveyors 130, heat can be uniformly supplied to the transported object.

<Additional structure of furnace equipment (gas supply)>
When the carbonization furnace 112 of the furnace facility 100 is a self-combustion furnace, the furnace facility 100 may include a plurality of gas supply units 161 .
The gas supply unit 161 is a part configured to supply gas (for example, a gas containing oxygen such as air) as an oxidizing agent required for combustion.
The gas is introduced to the gas supply unit 161 from the outside by, for example, a device not shown.
The plurality of gas supply units 161 include, for example, a gas supply unit 161a, a gas supply unit 161b, a gas supply unit 161c, a gas supply unit 161d, and a gas supply unit 161e.
Hereinafter, the gas supply units 161 will be referred to by reference numerals 161a to 161e when they need to be distinguished from one another, and will be referred to by reference numeral 161 when they do not need to be distinguished from one another.

Each gas supply unit 161 is disposed inside the container 101 between adjacent conveyors 130 in the vertical direction and above the conveyor 130a.
In the case of FIG. 2, two gas supply units 161 are disposed between the vertically adjacent conveyors 130 and above the conveyor 130a.
However, the number and arrangement of the gas supply units 161 can be changed as appropriate.
The gas supply units 161a, 161b, 161c, 161d, and 161e can individually change the amount of gas they supply as appropriate.

By providing the gas supply unit 161, the gas required for carbonization can be supplied to the transported material.
Furthermore, by disposing the gas supply unit 161 between the conveyors 130 adjacent to each other in the vertical direction, gas can be supplied uniformly to the transported object.

When the gas supply unit 161 is provided, it is preferable that each conveyor 130 has a communication portion 135 through which gas can pass in the vertical direction.
The communication portion 135 is, for example, a hole that penetrates the upper and lower surfaces of the conveyor 130. The hole may have any shape as long as it is configured to reliably allow gas to pass through, and there are no particular limitations on the specific shape of the hole.
The communication section 135 is realized by employing a mesh conveyor as the conveyor 130, for example.

By providing the communication section 135, gas can move more easily up and down inside the container 101, allowing the gas required for carbonization to be supplied evenly.

<Control based on the components of the transported goods>
The furnace facility 100 may include multiple transported object analyzers 171 .
The transported goods analysis unit 171 is a means for analyzing the components of the transported goods.
The "components of the transported material" referred to here include, for example, the water content, fixed carbon, volatile matter, etc. contained in the transported material.

The plurality of transported item analysis units 171 include, for example, a transported item analysis unit 171a, a transported item analysis unit 171b, a transported item analysis unit 171c, a transported item analysis unit 171d, and a transported item analysis unit 171e.
Each of the transported object analysis units 171a to 171e is configured to be able to analyze the components of the transported object on each of the conveyors 130a to 130e and/or the components of the transported object near each of the conveyors 130a to 130e. Therefore, for example, the transported object analysis units 171a to 171e are installed at positions corresponding to the positions where the conveyors 130a to 130e are installed.
Hereinafter, the symbols 171a to 171e will be used to distinguish between the individual transported item analysis units 171. When the individual transported item analysis units 171 do not need to be distinguished, the symbol 171 will be used.

At least one of the transport speed of each conveyor 130 and the amount of material to be carbonized W1 fed from the raw material feeding section 141 is adjusted based on the analysis results of each transported material analyzing section 171.
For example, the control unit 170 can identify an optimal drying time for drying the transported object or an optimal reaction time for carbonizing the transported object based on the analysis results of each transported object analysis unit 171, and increase/decrease the conveying speed of at least one of the conveyors 130 or increase/decrease the amount of carbonized object W1 input based on the identified drying time or reaction time. As a specific example, the control unit 170 can identify an optimal drying time for drying the transported object or an optimal reaction time for carbonizing the transported object based on the analysis results of the transported object analysis unit 171a, and increase/decrease the conveying speed of the conveyor 130a located upstream of the transported object analysis unit 171a based on the identified drying time or reaction time. Similarly, the control unit 170 can individually increase/decrease the conveying speeds of the conveyors 130b to 130e located upstream of the transported object analysis unit 171a based on the analysis results of the transported object analysis units 171b to 171e.

In addition to or instead of adjusting at least one of the conveying speed of each conveyor 130 and the amount of carbonized material W1 fed from the raw material feeding section 141, the amount of heat supplied from each heat supply section 151 or the amount of gas supplied from each gas supply section 161 is adjusted based on the analysis results of each transported material analysis section 171.
For example, the control unit 170 can identify an optimal drying time for drying the transported object or an optimal reaction time for carbonizing the transported object based on the analysis results of each transported object analysis unit 171, and increase/decrease the amount of heat supplied from each heat supply unit 151 or the amount of gas supplied from each gas supply unit 161 based on the identified drying time or reaction time. Specifically, the control unit 170 can identify an optimal drying time for drying the transported object or an optimal reaction time for carbonizing the transported object based on the analysis results of the transported object analysis unit 171a, and increase/decrease the amount of heat supplied from the heat supply unit 151a located upstream of the transported object analysis unit 171a or the amount of gas supplied from the gas supply unit 161a based on the identified drying time or reaction time. Similarly, the control unit 170 can individually increase/decrease the amount of heat supplied from the heat supply units 151b to 151e or the amount of gas supplied from the gas supply units 161b to 161e located upstream of the transported object analysis unit 171a based on the analysis results of the transported object analysis units 171b to 171e.

<Regarding control based on gas components and/or gas temperature>
The furnace facility 100 may include multiple gas analyzers 172 .
The furnace equipment 100 may include a plurality of gas temperature measuring units 173 .
The furnace equipment 100 may include only one of the gas analysis unit 172 and the gas temperature measurement unit 173, or may include both.

The gas analysis unit 172 is a means for analyzing the components of the gas generated inside the container 101 (specifically, the carbonization furnace 112 and/or the drying chamber 111).
The term "gas" used here refers to exhaust gases and dry distillation gases generated by drying, combustion, or carbonization of transported materials.
The term "gas components" used herein refers to, for example, water vapor, carbon monoxide, hydrogen, carbon dioxide, hydrocarbons such as methane, and the like contained in the gas.

Each gas temperature measuring unit 173 is a means for measuring the temperature of the gas generated inside the container 101.

The plurality of gas analyzers 172 include, for example, a gas analyzer 172a, a gas analyzer 172b, a gas analyzer 172c, a gas analyzer 172d, and a gas analyzer 172e.
Each of the gas analyzers 172a to 172e is configured to be able to analyze the components of gases generated from the transported goods on each of the conveyors 130a to 130e and/or the components of gases generated from the transported goods near each of the conveyors 130a to 130e. Therefore, for example, the gas analyzers 172a to 172e are installed at positions corresponding to the positions where the conveyors 130a to 130e are installed.
Hereinafter, the reference numerals 172a to 172e will be used to distinguish between the gas analyzers 172. When no distinction is required between the gas analyzers 172, the reference numeral 172 will be used.

The plurality of gas temperature measuring units 173 include, for example, a gas temperature measuring unit 173a, a gas temperature measuring unit 173b, a gas temperature measuring unit 173c, a gas temperature measuring unit 173d, and a gas temperature measuring unit 173e.
Each of the gas temperature measuring units 173a to 173e is configured to be able to measure the temperature of gas generated from an object on each of the conveyors 130a to 130e and/or the temperature of gas generated from an object near each of the conveyors 130a to 130e. Therefore, for example, the gas temperature measuring units 173a to 173e are installed at positions corresponding to the positions where the conveyors 130a to 130e are installed.
Hereinafter, reference numerals 173a to 173e will be used to distinguish between the gas temperature measurement units 173. When no distinction is required between the gas temperature measurement units 173, reference numeral 173 will be used.

At least one of the conveying speed of each conveyor 130 and the amount of carbonized material W1 fed from the raw material feeding section 141 is adjusted based on the analysis results of each gas analysis section 172 and/or the measurement values of each gas temperature measuring section 173.
For example, the control unit 170 can increase/decrease the conveying speed of at least one of the conveyors 130 or increase/decrease the amount of carbonized material W1 fed based on the analysis results of each gas analyzer 172 and/or the measurement values of each gas temperature measuring unit 173. As a specific example, the control unit 170 can increase/decrease the conveying speed of the conveyor 130a located upstream of the gas analyzer 172a and/or the gas temperature measuring unit 173a based on the analysis results of the gas analyzers 172b to 172e and/or the measurement values of the gas temperature measuring units 173b to 173e. Similarly, the control unit 170 can individually increase/decrease the conveying speeds of the conveyors 130b to 130e located upstream of each of the conveyors 130b to 130e based on the analysis results of the gas analyzers 172b to 172e and/or the measurement values of the gas temperature measuring units 173b to 173e.

In addition to or instead of adjusting at least one of the conveying speed of each conveyor 130 and the amount of carbonized material W1 fed from the raw material feeding section 141, the amount of heat supplied from each heat supply section 151 or the amount of gas supplied from each gas supply section 161 is adjusted based on the analysis results of each gas analysis section 172 and/or the measurement values of each gas temperature measuring section 173.
For example, the control unit 170 can increase/decrease the amount of heat supplied from each heat supply unit 151 or increase/decrease the amount of gas supplied from each gas supply unit 161 based on the analysis results of each gas analysis unit 172 and/or the measurement values of each gas temperature measurement unit 173. As a specific example, the control unit 170 can increase/decrease the amount of heat supplied from the heat supply unit 151a or the amount of gas supplied from the gas supply unit 161a located upstream of the gas analysis unit 172a and/or the gas temperature measurement unit 173a based on the analysis results of the gas analysis unit 172a and/or the measurement values of the gas temperature measurement unit 173a. Similarly, the control unit 170 can individually increase/decrease the amount of heat supplied from the heat supply units 151b to 151e located upstream or the amount of gas supplied from the gas supply units 161b to 161e based on the analysis results of the gas analysis units 172b to 172e and/or the measurement values of the gas temperature measurement units 173b to 173e.

The furnace equipment according to this embodiment has the following advantages.
The conveyors 130 are arranged at intervals from each other in the vertical direction, the conveying directions of adjacent conveyors 130 in the vertical direction are opposite, and the conveyed goods conveyed by the upper conveyor 130 of adjacent conveyors 130 in the vertical direction fall at a position between the front end 131 and the rear end 132 in the conveying direction of the lower conveyor 130.This prevents the conveyed goods from piling up high on each conveyor 130, and reduces the size of each conveyor 130 in the conveying direction while maintaining the overall conveying distance, thereby making the furnace equipment 100 more compact.

Each conveyor 130 is positioned so that its front end 131 in the conveying direction is lower than its rear end 132. Therefore, any material that falls onto the conveyor 130 crumbles toward the front end 131, resulting in the material being spread evenly across the conveyor's 130 conveying surface to a roughly uniform layer thickness. This allows the material to be dried and carbonized evenly.

It is equipped with multiple heat supply units 151 that supply heat, and each heat supply unit 151 is positioned between vertically adjacent conveyors 130 and above the uppermost conveyor 130a, so the heat required for drying and carbonization can be uniformly supplied to the material to be carbonized W1.

The furnace is equipped with multiple gas supply units 161 that supply gas as an oxidizing agent. Each gas supply unit 161 is positioned between adjacent conveyors 130 in the vertical direction and above the uppermost conveyor 130a. This allows the gas required for carbonization to be uniformly supplied to the material to be carbonized W1 in the self-combustion carbonization furnace 112.

The conveyor 130 has a communication section 135 through which the gas supplied from the gas supply section 161 can pass in the vertical direction, making it easier for the gas to move in the vertical direction, and allowing the gas required for carbonization to be supplied evenly.

Second Embodiment

The conveyor 238 is driven by a drive unit (not shown) and is configured so that the conveying speed can be changed.

The height of the conveying surface of the conveyor 238 is substantially constant, that is, the conveyor 238 is not inclined.
The height of the conveying surface of the conveyor 238 is substantially the same as the height of the conveying surface at the front end 231 of the conveyor 230c located at the lowest level inside the first container 201. This allows the transported article to be smoothly transferred from the conveyor 230c to the conveyor 238.

The conveyor 238 need only be configured to transport the objects being transported, and its specific form is not particularly limited.

A raw material input section 241 is provided at the top of the first container 201.

The plurality of heat supplying units 251 include, for example, a heat supplying unit 251a, a heat supplying unit 251b, and a heat supplying unit 251c.
Each heat supplying section 251 is disposed inside the first container 201 between the conveyors 230 adjacent to each other in the vertical direction and above the conveyor 230a.

When the drying chamber 211 of the furnace equipment 200 is a self-combustion or self-heating type drying chamber, the furnace equipment 200 may be provided with a plurality of gas supply units 261 .
The plurality of gas supply units 261 include, for example, a gas supply unit 261a, a gas supply unit 261b, and a gas supply unit 261c.
Each gas supply unit 261 is disposed inside the first container 201 between the conveyors 230 adjacent to each other in the vertical direction and above the conveyor 230a.

Here, the self-heating type refers to a drying method in which the material to be carbonized W1 is oxidized and heated by contacting it with an oxidizing agent, thereby drying the material to be carbonized W1 itself. Examples of the oxidizing agent include oxygen and air.
Furthermore, warm air with a high temperature has a greater drying effect than cold air with a low temperature.

<Control based on the components of the transported goods>
The furnace facility 200 may include multiple transported object analyzers 271 .
The plurality of transported item analysis units 271 include, for example, a transported item analysis unit 271a, a transported item analysis unit 271b, and a transported item analysis unit 271c.

At least one of the transport speed of each conveyor 230 and the amount of material to be carbonized W1 fed from the raw material feeding section 241 is adjusted based on the analysis results of each transported material analyzing section 271.
For example, the control unit 270 can identify an optimal drying time for drying the transported objects based on the analysis results of each transported object analysis unit 271, and increase/decrease the transport speed of at least one of the conveyors 230 or increase/decrease the amount of carbonized material W1 input based on the identified drying time. As a specific example, the control unit 270 can identify an optimal drying time for drying the transported objects based on the analysis results of the transported object analysis unit 271a, and increase/decrease the transport speed of the conveyor 230a located upstream of the transported object analysis unit 271a based on the identified drying time. Similarly, the control unit 270 can individually increase/decrease the transport speeds of the conveyors 230b to 230c located upstream of each of the transported objects based on the analysis results of the transported object analysis units 271b to 271c.

In addition to or instead of adjusting at least one of the conveying speed of each conveyor 230 and the amount of carbonized material W1 fed from the raw material feeding section 241, the amount of heat supplied from each heat supply section 251 or the amount of gas supplied from each gas supply section 261 is adjusted based on the analysis results of each transported material analysis section 271.
For example, the control unit 270 can identify an optimal drying time for drying the transported object based on the analysis results of each transported object analysis unit 271, and increase/decrease the amount of heat supplied from each heat supply unit 251 or the amount of gas supplied from each gas supply unit 261 based on the identified drying time. Specifically, the control unit 270 can identify an optimal drying time for drying the transported object based on the analysis results of the transported object analysis unit 271a, and increase/decrease the amount of heat supplied from the heat supply unit 251a located upstream of the transported object analysis unit 271a or the amount of gas supplied from the gas supply unit 261a based on the identified drying time.

The furnace equipment 200 may include only one of the gas analysis unit 272 and the gas temperature measurement unit 273, or may include both of them.

At least one of the conveying speed of each conveyor 230 and the amount of carbonized material W1 fed from the raw material feeding section 241 is adjusted based on the analysis results of each gas analysis section 272 and/or the measurement values of each gas temperature measuring section 273.
For example, the control unit 270 can increase/decrease the conveying speed of at least one of the conveyors 230 or increase/decrease the amount of carbonized material W1 fed based on the analysis results of the gas analyzers 272 and/or the measurement values of the gas temperature measuring units 273.

The furnace equipment according to this embodiment has the following advantages.
The conveyors 230 are arranged at intervals from each other in the vertical direction, the conveying directions of adjacent conveyors 230 in the vertical direction are opposite, and the conveyed goods conveyed by the upper conveyor 230 of adjacent conveyors 230 in the vertical direction fall at a position between the front end 231 and the rear end 232 in the conveying direction of the lower conveyor 230. This prevents the conveyed goods from piling up high on each conveyor 230, and reduces the size of each conveyor 230 in the conveying direction while maintaining the overall conveying distance, thereby making the furnace equipment 200 more compact.

Each conveyor 230 is positioned so that its front end 231 in the conveying direction is lower than its rear end 232. Therefore, any material that falls onto the conveyor 230 crumbles toward the front end 231, resulting in the material being spread evenly across the conveyor 230's conveying surface to a roughly uniform layer thickness. This allows the material to be dried and carbonized evenly.

It is equipped with multiple heat supply units 251 that supply heat, and each heat supply unit 251 is positioned between vertically adjacent conveyors 230 and above the uppermost conveyor 230a, so the heat required for drying can be uniformly supplied to the carbonized material W1.

It is equipped with multiple gas supply units 261 that supply gas as an oxidizing agent, and each gas supply unit 261 is positioned between vertically adjacent conveyors 230 and above the uppermost conveyor 230a. This allows the gas required for drying to be uniformly supplied to the carbonized material W1 in the self-combustion or self-heating drying chamber 211.

The conveyor 230 has a communication section 235 through which the gas supplied from the gas supply section 261 can pass in the vertical direction, making it easier for the gas to move in the vertical direction, and allowing the gas required for drying to be supplied evenly.
