International Publication No. 2005/033582 Pamphlet

  By the way, in the conventional combustion apparatus, the outer cylinder portion 10 is formed of a material having a high melting point so that the heat of the heat-resistant fluid that is the inner cylinder portion 20 can be sufficiently resisted even if the heat is transmitted. Although cooling is performed by the cooling water ejected from the cooling water ejection port 8, the cooling by the cooling water is not sufficient, and an expensive material must be used for the outer cylindrical portion 10, and the manufacturing cost of the entire apparatus increases. There was a problem that.

  The present invention has been made in view of the above-described problems, and allows water to flow between the outer cylinder part and the inner cylinder part to ensure cooling of the outer cylinder part and to make the material of the outer cylinder part inexpensive. Thus, an object of the present invention is to provide a combustion apparatus that reduces the manufacturing cost.

  In order to achieve such an object, the combustion apparatus of the present invention is provided with a fluid in which the supply of air is shut off and water mixed with the combustion product is supplied, and the water in the fluid is pyrolyzed to burn the combustion product. A combustion chamber body that exhausts the gas after combustion, a fluid supply unit that supplies the fluid to the combustion chamber body, surrounds the combustion chamber body, and is capable of rotationally driving the combustion chamber body A lower opening for supplying a fluid to the lower center of the combustion chamber body, and an upper portion communicating with the combustion chamber body at the upper center of the combustion chamber body for discharging exhaust gas. An opening is provided, the combustion chamber body is composed of an outer cylinder portion and an inner cylinder portion, and the inner cylinder portion of the combustion chamber body is composed of a granular material that can be melted by heat from combustion of the combustion product. The inner wall of the combustion chamber is formed by being pressed against the outer cylinder by the centrifugal force of the combustion chamber. A water supply unit configured to supply water so as to flow down the inner side surface of the outer cylinder part by being pressed against the outer cylinder part side by centrifugal force when the combustion chamber body rotates, Provided with at least one of an upper part and a lower part of the combustion chamber body, and a water vapor take-out part for taking out water vapor evaporated in the process in which water from the water supply part flows down the inner side surface of the outer cylinder part. It is configured.

According to this, in the combustion chamber, a fluid in which water is mixed with the combustion product is supplied in a state where the supply of air is shut off, and the water in the fluid is thermally decomposed into oxygen and hydrogen. Combustion is almost completely burned by oxygen. In addition, the heat-resistant fluid forms an inner cylinder due to the centrifugal force generated by the rotation of the combustion chamber body, and the infrared rays are reflected on the inner surface of the dissolved heat-resistant fluid, and the inside of the combustion chamber becomes very hot. Then, a rising vortex is generated, the inside of the combustion chamber is at a high temperature and a high pressure, and the combustion product is surely almost completely combusted by oxygen obtained by thermally decomposing water in the fluid.
In this case, since the supply of air to the combustion chamber body is interrupted, the supply of nitrogen is almost eliminated, so that the generation of nitrogen oxides other than those caused by the combustion products is suppressed. As a result, the exhaust gas becomes clean.
Further, when water is supplied from the water supply part, the water from the water supply part passes through the gaps between the powder particles and is pressed against the outer cylinder part side by centrifugal force due to the rotation of the combustion chamber body. It will flow down the inside surface.
As a result, in the combustion chamber, water flows down to the inner side surface of the outer cylinder part, and this water evaporates due to heat from combustion from the inner cylinder part side, and flows down the inner side surface of the outer cylinder part. Since heat due to combustion is taken away by latent heat when water evaporates, the heat due to combustion is not directly transmitted to the outer cylinder part, and the outer cylinder part is reliably cooled. Therefore, it is not necessary to use an expensive material such as tungsten that can withstand high temperatures and is difficult to process in the outer cylinder portion, and the manufacturing cost of the entire apparatus can be reduced.
Furthermore, when the water on the inner side surface of the outer cylinder portion evaporates to become water vapor, the water vapor is taken out from the water vapor extraction portion through the gaps between the powder particles.

Further, if necessary, an upper surface plate is provided on the outer wall surface of the outer cylinder portion so as to face the outer surface of the upper wall with a space therebetween, and a tubular rotating shaft whose lower end is coaxially connected to the upper opening is provided on the upper surface plate. The water supply unit is configured to allow water to flow down on the inner surface of the tubular rotary shaft and to flow from the upper opening.
In order to supply water from the water supply unit into the outer cylinder, water is allowed to flow down to the inner surface of the upper rotary shaft and flow from the upper opening. Thereby, since the water of a water supply part flows through an upper rotating shaft, it can cool the upper rotating shaft side with respect to the heat | fever which exhausted and flowed out from the upper opening to the upper rotating shaft side. As a result, deformation of the upper rotary shaft and the like is prevented, and the apparatus can be operated stably.

Further, if necessary, the water vapor take-out part is constituted by a space formed between the outer surface of the upper wall of the outer cylinder part and the upper surface plate, and the outer peripheral side is formed with the axial center side of the space as the water vapor inlet. It is an outlet for water vapor.
In this water vapor extraction part, the water vapor flowing out from the upper opening is taken out together with the exhaust gas resulting from the combustion of the combustion products from the space formed between the outer surface of the upper wall of the outer cylinder part and the upper surface plate.
In this case, it is effective to provide a turbine that has a plurality of blades on the outlet side of the space and receives water vapor flowing into the space from the inlet and applies a rotational force to the combustion chamber body.
As a result, when combustion products are burned in the combustion chamber, water vapor and exhaust gas are guided to the turbine from the space formed between the outer wall of the upper wall of the outer cylinder and the upper plate, and the combustion chamber rotates by this turbine. Therefore, the combustion chamber body can be automatically rotated without rotating the combustion chamber body using a device or the like for driving the combustion chamber body. Therefore, an energy saving effect can be expected.

Further, a plurality of guide tubes that guide water vapor and water from the inlet of the space to the turbine on the outlet side are arranged radially in the space.
As a result, the guide pipe guides the water vapor from the entrance of the space toward the turbine on the outlet side, so that the water vapor and the exhaust gas reliably act on the blades of the turbine. Further, when the water from the water supply unit is guided toward the turbine by the guide pipe, the water evaporates by heat from the exhaust in the guide pipe and becomes water vapor, so the water vapor generated in the guide pipe also acts on the blades of the turbine. Thus, the turbine can be operated efficiently. Also, even if the exhaust passing through the guide pipe is hot, the water guided by the guide pipe cools the guide pipe from the inside, preventing deformation of the guide pipe and turbine blades that may be caused by the heat of the exhaust. can do. The water that has not evaporated evaporates by colliding with the blades of the turbine.
In this case, it is effective to use a cooling passage through which water flows outside the guide tube.
As a result, even if the exhaust gas passing through the guide tube is hot, the water in the cooling passage cools the guide tube, so that it is possible to prevent deformation of the guide tube and turbine blades that may be caused by the heat of the exhaust gas. it can. Further, when the water in the cooling passage is heated from the guide tube and evaporates, the combustion chamber body rotates, so that water vapor having a specific gravity smaller than that of water moves to the axial center side and flows out from the guide tube.
Further, water vapor is generated outside the guide tube by heat such as exhaust gas, and this water vapor is sent to the blades of the turbine. Therefore, the turbine can efficiently apply a rotational force to the combustion chamber body.

Further, if necessary, the lower surface plate is configured such that the water vapor extraction portion is formed by a through hole formed in the lower wall of the outer cylindrical portion, and faces the lower wall outer surface of the outer cylindrical portion with a space from the lower wall outer surface. And a turbine that has a plurality of blades on the outer periphery of the space and receives the water vapor from the through-hole and applies a rotational force to the combustion chamber body.
In this water vapor extraction section, when the water vapor is extracted from the through-hole that is the water vapor extraction section, the water vapor is guided to a turbine provided in a space formed between the lower wall outer surface of the outer cylinder portion and the lower surface plate. As a result, when combustion products are combusted in the combustion chamber, the combustion chamber is rotated by the turbine. Therefore, the combustion chamber is not rotated without using a device for driving the combustion chamber. It can be rotated by itself. Therefore, an energy saving effect can be expected.

Further, if necessary, a plate-like filter is provided that covers the lower wall inner surface of the outer cylinder part and allows water and water vapor from the water supply part to pass therethrough and has a large number of holes through which the granular material does not pass. ing.
Thereby, since the lower wall of the outer cylinder part is covered with the filter, it is possible to prevent the powder particles from flowing out from the through hole or the like and to prevent the water vapor flowing out from the through hole side from being blocked.

  Furthermore, if necessary, the fluid supply part passes through a fluid storage tank in which the fluid is put, and a rotating shaft that is inserted into the lower opening and protrudes from the outer surface of the lower wall of the outer cylinder part. A fluid injection nozzle, and a fluid supply pipe that is connected to the fluid storage tank and the fluid injection nozzle, and is provided with a high-pressure pump that pumps the fluid from the fluid storage tank toward the fluid injection nozzle. It was configured with. The fluid can be reliably injected from the fluid injection nozzle.

If necessary, the fluid injection port side of the fluid injection nozzle protrudes from the inner surface of the lower wall of the outer cylinder portion into the combustion chamber body.
Thereby, the burning part in an inner cylinder part can be kept away from the lower part of an outer cylinder part, and the deformation | transformation of the lower part of an outer cylinder part can be prevented.

Further, if necessary, a hydrogen injection nozzle provided coaxially with the fluid injection nozzle inside the fluid injection nozzle, and an oxygen injection nozzle provided coaxially with the hydrogen injection nozzle inside the hydrogen injection nozzle. The configuration is provided.
By injecting hydrogen and oxygen at appropriate times from the hydrogen injection nozzle and the oxygen injection nozzle, ignition can be ensured and combustion can be stabilized.
In this case, a gas recovery pipe for recovering a gas containing water vapor exhausted from the combustion chamber body is connected to the outer chamber body, and a part of the gas from the gas extraction pipe connected to the oxygen injection nozzle is supplied to the outer chamber body. It is effective to provide a gas recirculation conduit for recirculating gas into the combustion chamber by injecting gas from an oxygen injection nozzle.
As a result, the gas injected from the fluid injection nozzle inside the fluid injection nozzle diffuses the fluid from the fluid injection nozzle widely into the combustion chamber, so the distribution of the fluid becomes uniform and the inner cylinder It is possible to efficiently burn the combusted material in the section.

Further, if necessary, a gap is formed between the fluid injection nozzle and the lower opening so that ash in the combustion chamber can be discharged, and ash is discharged outside the outer chamber in the lower portion of the outer chamber. An ash discharge port for discharging, an ash discharge passage for receiving ash from the lower opening and guiding it to the ash collection outlet, and a discharge passage opening / closing mechanism for opening and closing the ash discharge passage are provided.
The ash generated in the combustion chamber falls to the lower part of the combustion chamber, passes through the lower opening, and is guided from the ash discharge passage portion to the ash discharge port. Thereby, ash can be taken out from the ash outlet.

Furthermore, a water discharge hole for discharging water that has not evaporated in the process of flowing down the inner surface of the outer cylinder part to the outside of the outer cylinder part is provided on the outer periphery of the lower part of the outer cylinder part. Water is received by the ash content discharge passage and discharged to the outside of the outer chamber together with the ash content.
Thereby, the water from the water supply part that has not evaporated in the combustion chamber is discharged from the water discharge hole. Therefore, excess water does not remain in the combustion chamber, and a situation that affects the combustion of combustion products can be prevented.

Furthermore, if necessary, a duct communicating with the upper opening of the combustion chamber body is provided at the upper portion of the outer chamber body, and a duct for opening and closing the duct for entering the combustion material and opening and closing the duct are provided in the duct.

The water flows down the inner side surface of the outer cylinder part, and this water evaporates due to the heat from the combustion from the inner cylinder part side, and the latent heat generated when the water flowing down the inner side surface of the outer cylinder part evaporates Heat is deprived, and heat from combustion is not directly transmitted to the outer cylinder part, so that the outer cylinder part is reliably cooled.

The combustion device is provided with combustion chamber body driving means 170. The combustion chamber body driving means 170 is used, for example, before combustion of the combustion chamber body 1, and is provided at the lower portion of the outer chamber body 50. The combustion chamber body driving means 170 includes a motor 175 and a gear device 170a that transmits the rotational force of the motor 175 to rotate the lower rotating shaft 17 to rotate the combustion chamber body 1. Yes.
The gear device 170a includes a shaft 171 to which a rotation shaft of a motor 175 is coupled, a first gear 172 provided on the shaft 171, a second gear 173 meshed with the first gear 172 and provided on the lower rotation shaft 17. It is equipped with. The shaft 171 is rotatably supported by the outer chamber body 50 via a bearing 174.
The motor 175 also functions as a generator. In the power generation of the motor 175, the combustion products burn in the combustion chamber body 1, and a rotational force is applied to the combustion chamber body 1 by the turbines 130 and 150, and this rotational force is transmitted via the lower rotating shaft 16 and the gear device 170a. When transmitted to the motor 175, the rotational force is used as power.

  In addition, as shown in FIG. 2, the combustion apparatus includes a lubricating oil circulation conduit that circulates and supplies lubricating oil to a bearing 174, a gear device 170a, a lower bearing 57, and an upper bearing 56 that support a shaft 171. 180 is provided. The lubricating oil circulation pipe 180 is provided with a filter 181 for filtering out foreign substances in the oil and a circulation pump 182 for circulating the oil.

In order to use this combustion apparatus, as shown in FIG. 9A, for example, it is made of aluminum, and the fluid injection port 32a side and the through-hole 124 of the fluid injection nozzle 32 of the fluid supply unit 30 are covered with a cover 190. And temporarily let the powder and granular material 21 flow into the outer cylinder portion 10 through the duct 61, for example. At this time, since the lower wall 12 of the outer cylindrical portion 10 is covered with the filter 122, a situation in which the powder 21 from the through hole 121 and the like flows out is prevented.
In this state, as shown in FIG. 9B, the combustion chamber body 1 is rotationally driven using the combustion chamber body driving means 170. At this time, the granular material 21 in the outer cylinder portion 10 is pressed against the outer cylinder portion 10 side by the centrifugal force of the combustion chamber body 1.
Next, as illustrated in FIG. 9C, water W is supplied from the water supply unit 100. At this time, the water W from the water supply unit 100 flows down the inner side of the upper bearing 56 and flows down the inner surface of the upper rotary shaft 16. The water W flowing on the inner surface of the upper rotary shaft 16 is pressed against the wall portion side of the upper rotary shaft 16 by the centrifugal force generated by the rotation of the combustion chamber body 1. Then, as shown in FIGS. 1, 4, and 5, the water flows into the cooling passage 114 outside the guide tube 115 from the lower end of the upper rotating shaft 16, and when the space constituting the cooling passage 114 is filled with this water, Water flows into the outer cylinder portion 10 from the upper opening 3. The water that has flowed into the outer cylinder part 10 passes through the gap between the powder bodies 21 and is pressed against the outer cylinder part 10 side by centrifugal force due to the rotation of the combustion chamber body 1 and flows down the inner surface of the outer cylinder part 10. Go.

  Then, as shown in FIG. 9D, in a state where oxygen is injected from the oxygen injection nozzle 37 and hydrogen is injected from the hydrogen injection nozzle 36, the gas mixed with oxygen and hydrogen injected by the ignition device 45 is ignited. Then, the cover 190 is melted by the combustion of hydrogen with oxygen, and the temperature inside the combustion chamber body 1 is raised to a high temperature.

  Next, as shown in FIG. 9 (e), the high pressure pump 33 of the fluid supply unit 30 is operated to inject the fluid from the fluid injection nozzle 32. As a result, the water in the fluid is thermally decomposed into oxygen and hydrogen, and the combustion product starts to burn by the oxygen and oxygen supplied from the oxygen injection nozzle 37. When combustion reaches a steady state, the oxygen injection from the oxygen injection nozzle 37 and the hydrogen injection from the hydrogen injection nozzle 36 are stopped. In order to stabilize the combustion, ignition by the ignition device 45, injection of oxygen from the oxygen injection nozzle 37, and injection of hydrogen from the hydrogen injection nozzle 36 may be performed in a timely manner.

In a steady state, as shown in FIG. 1 to FIG. 8, ascending vortices are generated in the combustion chamber body 1, the inside of the combustion chamber body 1 is at a high temperature and high pressure, and the water in the fluid is burned by oxygen which is thermally decomposed. Things are almost completely burned. That is, at this time, in the combustion chamber body 1, the granular material 21 dissolved by the centrifugal force generated by the rotation of the combustion chamber body 1 approaches a vertical shape and becomes substantially cylindrical. Infrared rays reflect each other, become extremely hot, and almost complete combustion takes place. In the combustion chamber body 1, other gases such as hydrogen, carbon dioxide, water vapor, and excess oxygen are generated and flow out of the combustion chamber body 1 from the upper opening 3.
At this time, since the fluid injection port 32a side of the fluid injection nozzle 32 protrudes into the combustion chamber body 1 from the inner surface of the lower wall 12 of the outer cylinder portion 10, the inner cylinder portion is formed from the lower portion of the outer cylinder portion 10. The burning part in 20 can be kept away, and the deformation | transformation of the lower part of the outer cylinder part 10 can be prevented.

  At this time, in the combustion chamber body 1, the water W flows down to the inner side surface of the outer cylinder portion 10, and the water W evaporates due to heat generated by combustion from the inner cylinder portion 20 side. Since the heat generated by the combustion is taken away by the latent heat generated when the water W flowing down the inner surface of the cylindrical portion 10 evaporates, the heat generated by the combustion is not directly transmitted to the outer cylindrical portion 10, and the outer cylindrical portion 10 is reliably cooled. It is. As a result, it is not necessary to use an expensive material that can withstand high temperatures and is difficult to process, such as tungsten, for the outer cylinder portion 10, and the manufacturing cost of the entire apparatus can be reduced.

  Further, since the water supply unit 100 causes the water W to flow down from the upper opening 3 through the cylindrical body 58 to the inner surface of the upper rotary shaft 16, The upper rotating shaft 16 side can be cooled with water W from the water supply unit 100. This prevents the upper rotary shaft 16 and the like from being deformed, so that the apparatus can be operated stably.

Further, when the water W on the inner side surface of the outer cylinder portion 10 evaporates to become water vapor, the water vapor passes through the gaps between the granular materials 21, and from both the upper water vapor extraction portion 110 and the lower water vapor extraction portion 120. It is taken out.
In the upper water vapor extraction section 110, the water vapor flowing out from the upper opening 3 is extracted from the space formed between the outer surface of the upper wall 11 of the outer cylinder section 10 and the upper surface plate 14 together with the exhaust gas resulting from combustion of combustion products. .
At this time, water vapor and exhaust gas are guided to the upper turbine 130 by this space. Thus, when the combustion product is burned in the combustion chamber body 1, the combustion chamber body 1 is rotated by the upper turbine 130, so that the combustion chamber body 1 does not rotate by the combustion chamber body driving means 170. The body 1 rotates by itself. Therefore, an energy saving effect can be expected.

Further, since a plurality of guide pipes 115 are arranged radially in the space 111, the water vapor is guided from the inlet 111 a of the space 111 toward the upper turbine 130 on the outlet 111 b side, and the water vapor and the exhaust are discharged to the blades 131 of the upper turbine 130. Will work reliably.
Furthermore, since the water in the cooling passage 114 cools the guide tube 115 even when the exhaust gas passing through the guide tube 115 is hot, the guide tube 115 that may be caused by the heat of the exhaust, the blades 131 of the upper turbine 130, etc. Can be prevented from being deformed. Further, when the water in the cooling passage 114 is heated and evaporated by the exhaust gas passing through the guide tube 115, the combustion chamber body 1 is rotating, so that the water vapor having a specific gravity smaller than that of the water moves to the axial side, and the guide tube It flows out from 115. Furthermore, water flows into the inside of the guide tube 115 from the hole 118 provided in the guide tube 115, and this water is evaporated by the heat of the exhaust gas to become water vapor. Therefore, since water vapor is generated inside and outside the guide tube 115 and this water vapor is sent to the blades 131 of the upper turbine 130, the upper turbine 130 can efficiently apply a rotational force to the combustion chamber body 1.
Further, the water that has flowed into the guide tube 115 from the hole 118 and the like and could not be evaporated in the guide tube 115 collides with the blades 131 of the upper turbine 130 and evaporates.

Further, water vapor and exhaust from the outlet 132 of the upper turbine 130 are injected into the upper stationary blade 140, and the combustion chamber body 1 is also rotated by the repulsive force generated by this injection. Therefore, also by this, the combustion chamber body 1 can be efficiently rotated by burning the combustion products in the combustion chamber body 1.
Further, the fine ash mixed in the exhaust gas injected from the injection port 132 of the upper turbine 130 hits the inclined plate body 141 of the upper stationary blade 140 and falls to the lower part of the outer chamber body 50.

Next, in the lower water vapor extraction section 120, the water vapor is extracted from the through hole 121 which is the water vapor extraction section 120. At this time, the water vapor flowing out from the through hole 121 is guided to the lower turbine 150 provided in the space formed between the outer surface of the lower wall 12 of the outer cylinder portion 10 and the lower surface plate 15. Thus, when the combustion product is burned in the combustion chamber body 1, the combustion chamber body 1 is also rotated by the lower turbine 150, so that the combustion chamber body driving means 170 does not have to rotate the combustion chamber body 1. The combustion chamber body 1 can be rotated by itself.
Further, water vapor and exhaust from the jet port 152 of the lower turbine 150 are injected into the lower stationary blade 155, and the combustion chamber body 1 is also rotated by the repulsive force due to this injection. Therefore, also by this, the combustion chamber body 1 can be efficiently rotated by burning the combustion products in the combustion chamber body 1.
Further, the water W from the water supply unit 100 that has not evaporated in the combustion chamber body 1 is discharged from the water discharge hole 160. Therefore, excess water W does not remain in the combustion chamber body 1, and a situation that adversely affects the combustion of combustion products can be prevented.

  In the steady state of combustion, rotational force is applied to the combustion chamber body 1 by the upper turbine 130 and the lower turbine 150, so that the combustion chamber body driving means 170 rotates the combustion chamber body 1 at an appropriate time. Stop. Moreover, when the rotational force of the combustion chamber body 1 by the upper turbine 130 and the lower turbine 150 is large, this rotational force is taken out via the gear device 170a and is generated by the generator (motor 175). Therefore, the motive power from the combustion chamber body 1 can be taken out as electric power.

Water vapor and exhaust gas that have passed through the upper turbine 130 and the lower turbine 150 of the combustion chamber body 1 and reached the space between the outer chamber body 50 and the combustion chamber body 1 are recovered by the gas recovery pipe 90. The gas recovered by the gas recovery pipe 90 is centrifuged by the gas centrifuge 91 and separated for each type of gas. Among these, water vapor is liquefied and stored in the water storage tank 101.
In addition, a part of the gas recovered by the gas recovery pipe 90 is injected into the combustion chamber body 1 through the gas recirculation conduit 93, but the oxygen injection nozzle 37 is injected into the fluid injection nozzle 32 inside the fluid injection nozzle 32. Since it is provided coaxially with the nozzle 32, gas is injected from the center of the fluid. The gas injected from the oxygen injection nozzle 37 causes the fluid to diffuse widely into the combustion chamber body 1, the distribution of the fluid becomes uniform, and the combustion of the combustion in the inner cylinder portion 20 is efficient. Can be done.

  Further, the ash generated in the combustion chamber body 1 falls to the lower part of the combustion chamber body 1 and is scraped out by the drill 35 provided on the outer periphery of the fluid injection nozzle 32 and passes through the lower opening 2 to discharge the ash content. The passage 71 is led to the ash outlet 70. In this process, the ash discharge passage portion 71 is cooled by the cooling water flowing through the cooling water passage 78.

Furthermore, the ash content discharge passage portion 71 is opened and closed by a discharge passage portion opening / closing mechanism 72.
Specifically, the pair of discs 75 are both rotated by the rotation of the shaft portion 76, the cylindrical body 74 is opened by the hole 75 a of the disc 75 on the receiving portion 73 side, and the cylindrical shape is formed by the disc 75 on the ash content outlet 70 side. When the body 74 is closed, the ash content on the receiving portion 73 side passes through the hole 75a together with the gas in the outer chamber body 50 from the hole 75a of the disc 75 on the receiving portion 73 side, and the disc 75 and the ash content discharge port 70 on the receiving portion 73 side. Ashes accumulate in the disk 75 on the side.
Then, when the pair of discs 75 further rotate, the disc 75 on the receiving portion 73 side closes the cylindrical body 74, and the hole 75 a of the disc 75 on the ash content outlet 70 side opens the cylindrical body 74, the receiving portion Ash and gas accumulated between the disk 75 on the 73 side and the disk 75 on the ash outlet 70 side are discharged from the ash outlet 70. Thereby, ash can be taken out from the combustion apparatus. Further, the gas accumulated between the disk 75 on the receiving portion 73 side and the disk 75 on the ash content discharge port 70 side has a high atmospheric pressure that is substantially equal to that of the outer chamber body 50, and the ash content together with this gas becomes the ash content discharge port. As it leaves from 70, ash is discharged smoothly.

Thereafter, when the pair of discs 75 rotate, the cylindrical body 74 is opened by the hole 75a of the disc 75 on the receiving portion 73 side, and the cylindrical body 74 is closed by the disc 75 on the ash content outlet 70 side, the receiving portion Since the gas in the space between the disk 75 on the 73 side and the disk 75 on the ash content outlet 70 side has a pressure substantially equal to the atmospheric pressure, the gas enters from the outer chamber 50 together with the ash and the combustion chamber 1 Some atmospheric pressure fluctuation occurs. Due to this atmospheric pressure fluctuation, the ash that has solidified after melting in the combustion chamber body 1 and in the vicinity of the lower portion can be crushed.
Further, since the cylindrical body 74 is normally closed by any one of the pair of disks 75, the combustion chamber body 1 and the outside of the outer chamber body 50 are not directly communicated with each other via the outer chamber body 50. Compared with the case where a mechanism for simply opening and closing the cylindrical body 74 is provided, water and exhaust gas are not discharged from the ash outlet 70 so that the gas recovery efficiency of the gas recovery pipe 90 can be improved.

Further, for example, when a combustible material such as asbestos or wood is introduced from the combustible material inlet 62, when the duct 61 is opened by the duct opening / closing mechanism 63, the combustible material goes down the duct 61, and from the upper opening 3 to the combustion chamber. Put in the body 1.
Specifically, when the pair of disks 65 are both rotated by the rotation of the shaft portion 66 and the duct 61 is opened by the hole 64 of the disk 65 on the receiving portion 73 side, the disk 65 on the combustion material inlet 62 side is moved. The duct 61 is closed, and the combustible material enters between the disk 65 on the upper side bearing 56 side and the disk 65 on the combustible material inlet 62 side.
When the pair of discs 65 further rotate, for example, a long wood or the like is cut with a cutter at the opening edge of the hole 64. Next, when the pair of discs 65 further rotate, the duct 61 is closed by the disc 65 on the combustible inlet 62 side, and the duct 61 is opened by the hole 64 of the disc 65 on the upper bearing 56 side. Thus, the combustible material between the disk 65 on the combustion substance inlet 62 side and the disk 65 on the upper bearing 56 side enters the upper bearing 56 and enters the combustion chamber body 1 from the upper opening 3 via the upper rotating shaft. .

As a result, the combustion product can be introduced into the combustion chamber body 1 from other than the fluid supply unit 30.
At this time, the gas in the space between the disk 65 on the combustor input port 62 side and the disk 65 on the upper side bearing 56 side has an atmospheric pressure substantially equal to the atmospheric pressure. Enters and some atmospheric pressure fluctuations in the combustion chamber body 1 occur. This atmospheric pressure fluctuation can also crush the ash that has solidified after melting in the combustion chamber body 1 and in the vicinity of the lower part. After that, when the pair of disks 65 are rotated and the duct 61 is closed by the disk 65 on the combustion substance inlet 62 side and the duct 61 is opened by the hole 64 of the disk 65 on the upper bearing 56 side, the same as above. Combustion material enters the space between the disk 65 on the combustion substance inlet 62 side and the disk 65 on the upper bearing 56 side, and between the disk 65 on the combustion substance inlet 62 side and the disk 65 on the upper bearing 56 side. The gas in the space is discharged to the outside of the outer chamber body 50 from the hole 64 of the disk 65 on the combustion substance inlet 62 side.

  Further, since the duct 61 is normally closed by any one of the pair of disks 65, the combustion chamber body 1 and the outside of the outer chamber body 50 are not directly communicated with each other via the outer chamber body 50. Compared with the case where a mechanism for opening and closing 61 is provided, water vapor and exhaust gas are not exhausted from the upper bearing 56 so much, so that the gas recovery efficiency of the gas recovery pipe 90 can be improved.
