[0007] Patent Document 1: International Publication No. 2005Z033582 Pamphlet

[0008] By the way, in the combustion apparatus described above, the outer cylinder portion 10 is formed of a material having high heat resistance so as to sufficiently withstand the heat even when heat is transmitted from the inner cylinder portion 20, and is cooled. Cooled by cooling water ejected from water outlet 8. However, assuming that cooling with cooling water is not sufficient, the outer cylinder part 10 must be made of an expensive material with higher heat resistance, which increases the manufacturing cost of the entire device. there were.

[0009] The present invention has been made in view of the above problems, and water is allowed to flow between the outer cylinder part and the inner cylinder part to reliably cool the outer cylinder part, and the material of the outer cylinder part is inexpensive. The purpose is to provide a combustion apparatus that can reduce the manufacturing cost.

Disclosure of the invention

[0010] In order to achieve such an object, the combustion apparatus of the present invention shuts off the supply of air and supplies a fluid in which water is mixed with the combustion product to thermally decompose the water in the fluid. A combustion chamber body that combusts the combusted material and exhausts the gas after combustion, a fluid supply unit that supplies the fluid to the combustion chamber body, and surrounds the combustion chamber body and includes the combustion chamber body. An outer chamber body that is rotatably supported, and a lower opening for supplying a fluid is provided at the lower center of the combustion chamber body, and exhaust gas is exhausted by communicating with the combustion chamber body at the upper center of the combustion chamber body. An upper opening is formed, and 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 externally separated by a centrifugal force of the combustion chamber body. It is composed of a heat-resistant fluid that is pressed against the cylinder part and that fluidizes part of the powder and particles by the combustion heat of the combustion product. In the combustion apparatus thus formed, a water supply unit that supplies 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, and the combustion chamber And a water vapor outlet that is provided in at least one of the upper part and the lower part of the body and takes out water vapor that evaporates in the process where water from the water supply part flows down the inner surface of the outer cylinder part. is there.

[0011] 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 interrupted, and the water in the fluid is thermally decomposed into oxygen and hydrogen. The combustion product is almost completely burned by this 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 infrared rays are reflected by the inner surface of the dissolved heat-resistant fluid cylinder, causing the combustion chamber body to become very hot. As a result, ascending vortices are generated in the combustion chamber, and the combustion chamber is at a high temperature and high pressure, so that the combustion material is surely almost completely combusted by oxygen obtained by pyrolyzing 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, and the generation of nitrogen oxides other than those caused by combustion products is suppressed. As a result, the exhaust gas is cleaner.

Further, when water is supplied from the water supply unit, the water from the water supply unit 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 flows down the inner side of the. As a result, in the combustion chamber, water flows down to the inner surface of the outer cylinder part, and this water evaporates due to the heat generated by the combustion of the inner cylinder part side force. Since heat is taken away, the heat from combustion is not directly transferred to the outer cylinder part, and the outer cylinder part is reliably cooled. For this reason, it is not necessary to use an expensive material such as tungsten, which is difficult to process although it can withstand high temperatures, and the manufacturing cost of the entire apparatus can be reduced.

Furthermore, when the water on the inner side surface of the outer cylinder part evaporates to become water vapor, the water vapor is taken out from the water vapor take-out part through the gaps between the powder particles.

[0012] The present invention provides a tubular rotation in which an upper surface plate facing the outer surface of the upper wall is provided on the outer surface of the outer wall of the outer cylinder portion, and a lower end of the upper surface plate is coaxially connected to the upper opening. A shaft is provided, and the water supply portion is allowed to flow from the upper opening by allowing water to flow down to the inner surface of the tubular rotation shaft. Configure it to make people.

In order to supply water into the outer cylinder from the water supply part, water is allowed to flow down to the inner surface of the upper rotating shaft and the upper opening force is allowed to flow. As a result, the water in the water supply section flows through the upper rotary shaft, so that the upper rotary shaft side can be cooled against the heat generated by exhaust or combustion that has flowed out from the upper opening toward the upper rotary shaft. As a result, deformation of the upper rotating shaft and the like is prevented, and the apparatus can be operated stably.

[0013] In the present invention, the water vapor take-out part is constituted by a space formed between the outer wall of the upper wall of the outer cylinder part and the upper surface plate, and the axial side of the space is used as an inlet for water vapor. May be used as an outlet for water vapor.

In this water vapor take-out section, the water vapor force that flows out from the upper opening force is taken out from the space formed between the upper wall outer surface of the outer cylinder part and the upper surface plate together with the exhaust due to combustion of the combustion products.

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.

In this manner, when the combustion product is 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 portion and the upper surface plate, and this turbine causes the combustion chamber to Since the body is rotated, the combustion chamber body can be rotated without rotating the combustion chamber body using an apparatus for driving the combustion chamber body. Therefore, energy saving effect can be expected.

[0014] A plurality of guide tubes that guide water vapor and water from the inlet of the space to the turbine on the outlet side may be arranged radially in the space.

In this way, the guide tube guides water vapor from the inlet to the turbine on the outlet side, so that the water vapor and the exhaust gas reliably act on the blades of the turbine. In addition, when water from the water supply unit is guided to the turbine by the guide pipe, the water evaporates in the guide pipe due to the heat from the exhaust gas and becomes steam, so that the steam generated in the guide pipe also flows into the blades of the turbine. Thus, the turbine can be operated efficiently. Even if the exhaust gas passing through the guide tube is hot, the water guided by the guide tube cools the guide tube inward. Therefore, it is possible to prevent deformation of the guide tube and turbine blades that may be caused by the exhaust heat. The water that has not evaporated evaporates by colliding with the blades of the turbine.

In this case, it is effective to use the outside of the guide tube as a cooling passage through which water flows. In this way, the water in the cooling passage cools the guide pipe even if the exhaust gas passing through the guide pipe is hot, thus preventing deformation of the guide pipe and turbine blades that may be caused by the heat of the exhaust. be able to. Furthermore, 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 lower 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 bin, so that the turbine can efficiently apply a rotational force to the combustion chamber body. .

[0015] In the present invention, the water vapor extraction portion is configured by a through hole formed in the lower wall of the outer cylinder portion, and faces the lower wall outer surface of the outer cylinder portion with a space between the outer surface of the lower wall. A lower surface plate may be provided, and a turbine may be provided 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 water vapor is extracted from the through hole, which is the water vapor extraction section, the water vapor is introduced into a turbine bin provided in a space formed between the outer surface of the lower wall of the outer cylinder portion and the bottom plate. It is burned. As a result, when combustion products are burned in the combustion chamber body, the combustion chamber body is rotated by the turbine. Therefore, the combustion chamber body can be rotated without rotating the combustion chamber body using a device or the like that drives the combustion chamber body. Can be rotated. Therefore, an energy saving effect can be expected.

[0016] The present invention provides a plate-like filter that covers the inner surface of the lower wall 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 without passing the powder and granular material. Can be provided.

Thus, if the lower wall of the outer cylinder part is covered with the filter, it is possible to prevent the powder material having a constant through-hole force from flowing out and to prevent the water vapor flowing out from the through-hole side from being blocked.

[0017] In the present invention, the fluid supply unit includes a fluid storage tank in which the fluid is placed, Connected to the fluid injection nozzle that is inserted through the lower opening and penetrates the rotating shaft protruding from the lower wall outer surface force of the outer cylinder portion, the fluid storage tank, and the fluid injection nozzle, and from the fluid storage tank And a fluid supply pipe provided with a high-pressure pump for pumping the fluid to the fluid injection nozzle side. By rubbing in this way, the fluid can be reliably injected from the fluid injection nozzle.

[0018] Further, the fluid injection port side of the fluid injection nozzle may protrude from the inner surface of the lower wall of the outer cylinder portion into the combustion chamber body.

If it does in this way, 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.

[0019] The present invention provides a hydrogen injection nozzle provided coaxially with the fluid injection nozzle inside the fluid injection nozzle, and an oxygen injection provided coaxially with the hydrogen injection nozzle inside the hydrogen injection nozzle. A nozzle can also be provided.

Thereby, by injecting hydrogen and oxygen from the hydrogen injection nozzle and the oxygen injection nozzle in a timely manner, ignition can be ensured and combustion stability can be achieved. In this case, a gas recovery pipe for collecting the gas containing water vapor exhausted from the combustion chamber physical strength is connected to the outer chamber body, and a gas such as the gas extraction pipe power is connected to the oxygen injection nozzle. It is effective to provide a gas recirculation pipe for recirculating gas into the combustion chamber by partially injecting gas from the oxygen injection nozzle.

In this way, the fluid from the fluid injection nozzle that is injected from the fluid injection nozzle inside the fluid injection nozzle is diffused widely in the combustion chamber, so that the distribution of the fluid becomes uniform and the inside of the fluid injection nozzle becomes uniform. It is possible to efficiently burn the combusted material in the cylindrical portion.

[0020] In the present invention, a gap is formed between the fluid injection nozzle and the lower opening so that ash in the combustion chamber can be discharged, and the ash in the lower portion of the outer chamber is formed outside the outer chamber. There may be provided an ash discharge port that discharges ash, an ash discharge passage that receives ash from the lower opening and guides it to the ash collection outlet, and a discharge passage opening / closing mechanism that opens and closes the ash discharge passage.

The ash generated in the combustion chamber falls to the bottom of the combustion chamber, passes through the lower opening, It is led from the minute discharge passage part to the ash discharge port. Thereby, ash can be taken out from the ash outlet.

[0021] A water discharge hole for discharging water that has not evaporated in the process of flowing down the inner side 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 may be received by the ash discharge passage and discharged to the outside of the outer chamber together with the ash.

As a result, the water that has not been evaporated in the combustion chamber and has the power of the water supply section is discharged from the water discharge hole. Therefore, excess water does not remain in the combustion chamber, and the combustion of combustion products is not adversely affected.

[0022] Further, a duct communicating with the upper opening of the combustion chamber body is provided at an upper portion of the outer chamber body, and a combustion substance inlet port for introducing the combustion substance and an outside of the door that opens and closes the outside of the dust chamber. An opening / closing mechanism may be provided.

In this way, the combustion product can be introduced into the combustion chamber from other than the fluid supply unit.

[0051] Combustion device is provided with combustion chamber body driving means 170. The combustion chamber body driving means 170 is used, for example, before the combustion chamber body 1 is burned, 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 17 Oa that transmits the rotational force of the motor 175 and rotates the lower rotation shaft 17 to rotate the combustion chamber body 1! / RU

The gear device 170a includes a shaft 171 to which a rotating shaft of a motor 175 is coupled, a first gear 172 provided on the shaft 171, and a second gear 173 provided on the lower rotating shaft 17 in mesh with the first gear 172. And. The shaft 171 is rotatably supported by the outer chamber body 50 via a bearing 174.

The motor 175 also functions as a generator. The electric power generated by the motor 175 burns the combustion products 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 170 a. Is transmitted to the motor 175, and the rotation force is used as power.

In addition, as shown in FIG. 2, in the combustion apparatus, lubrication is performed by supplying lubricating oil to the bearing 174, the gear device 170a, the lower bearing 57, and the upper bearing 56 that support the shaft 171 in a circulating manner. An oil circulation line 180 is provided. The lubricating oil circulation pipe 180 is provided with a filter 181 for filtering and filtering out foreign substances in the oil and a circulation pump 182 for circulating oil.

In order to use this combustion apparatus, as shown in FIG. 11 (a), for example, the fluid injection port 32a of the fluid injection nozzle 32 of the fluid supply unit 30 is covered by a cover 190 formed of aluminum. The side and the through-hole 124 are temporarily covered, and the granular material 21 is caused to flow into the outer cylinder portion 10 through the duct 61. At this time, since the lower wall 12 of the outer cylindrical portion 10 is covered with the filter 122, it is possible to prevent the granular material 21 from flowing out even with the through-hole 121 equal force. In this state, as shown in FIG. 11 (b), when the combustion chamber body 1 is rotationally driven using the combustion chamber body driving means 170, the granular material 21 in the outer cylindrical portion 10 It is pressed against the outer tube 10 by centrifugal force.

Next, as shown in FIG. 11 (c), water W is supplied from the water supply unit 100. 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 rotating shaft 16 is pressed against the wall portion of the upper rotating shaft 16 by the centrifugal force generated by the rotation of the combustion chamber body 1. As shown in FIGS. 1, 4 and 5, the lower end force of the upper rotating shaft 16 also flows into the cooling passage 114 outside the guide pipe 115, and this water fills the space of the cooling passage 114. Water flows into the outer cylinder portion 10 from the upper opening 3. The water flowing into the outer cylinder part 10 passes through the gaps between the powder particles 21 and is pressed against the outer cylinder part 10 side by centrifugal force due to the rotation of the combustion chamber body 1 to flow down the inner surface of the outer cylinder part 10. Go.

Next, as shown in FIG. 11 (d), the ignition device 45 ignites with oxygen being injected from the oxygen injection nozzle 37 and hydrogen being injected from the hydrogen injection nozzle 36. The cover 190 is melted by the combustion of the mixed gas of oxygen and hydrogen, and the inside of the combustion chamber body 1 is heated.

Next, as shown in FIG. 11 (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 this oxygen and oxygen supplied from the oxygen injection nozzle 37. When the combustion reaches a steady state, the injection of oxygen from the oxygen injection nozzle 37 and hydrogen from the hydrogen injection nozzle 36 is stopped. In order to stabilize 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.

[0057] In a steady state, a rising vortex is generated in the combustion chamber body 1, the combustion chamber body 1 is at a high temperature and high pressure, and the combustion product is almost completely combusted by oxygen obtained by thermal decomposition of water in the fluid. . That is, at this time, in the combustion chamber body 1, the heat-resistant fluid obtained by dissolving a part of the powder and granular material becomes a substantially cylindrical shape due to the centrifugal force generated by the rotation of the combustion chamber body 1. Infrared rays are reflected on the inner surface of the heat-resistant fluid cylinder and become extremely hot, causing almost complete combustion. In the combustion chamber body 1, hydrogen, carbon dioxide, water vapor, and other gases such as excess oxygen are generated and flow out from the upper opening 3 to the outside of the combustion chamber body 1. At this time, since the fluid injection port 32a side of the fluid injection nozzle 32 protrudes from the lower wall 12 inner surface of the outer cylinder portion 10 into the combustion chamber body 1, the inner cylinder portion is formed from the lower portion of the outer cylinder portion 10. The burning part in 20 can be moved away, and deformation of the lower part of the outer cylinder part 10 can be prevented.

[0058] Further, in the combustion chamber body 1, water W flows down on the inner surface of the outer cylinder portion 10, and the water W evaporates due to heat generated by combustion of the inner cylinder portion 20 side force, and the outside W Since the water flowing down the inner surface of the cylindrical portion 10 is deprived of heat by the latent heat generated when the water W evaporates, the heat due to the combustion is not directly transferred to the outer cylindrical portion 10 and the cooling of the outer cylindrical portion 10 is ensured. Done. As a result, it is not necessary to use a high-priced material such as tungsten, which can withstand high temperatures but is difficult to process, so that the manufacturing cost of the entire apparatus can be reduced.

[0059] Since the water supply from the water supply unit 100 flows down the inner surface of the upper rotary shaft 16 through the cylindrical body 58 and flows in from the upper opening 3, the water W is used as the upper rotary shaft. 16 side can be cooled. This prevents the upper rotary shaft 16 and the like from being deformed by heat, so that the apparatus can be operated stably.

[0060] Further, when the water W on the inner surface of the outer cylindrical portion 10 evaporates to become water vapor, the water vapor passes through the gaps between the granular materials 21, and passes through the upper water vapor extraction portion 110 and the lower water vapor extraction portion 120. Taken from both.

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 from the combustion of the combustion products. It is.

In this way, water vapor and exhaust gas are guided to the upper turbine 130 by the space formed between the outer surface of the upper wall 11 and the upper plate 14, and the combustion chamber body 1 is rotated. Thus, the combustion chamber body 1 rotates without rotating the combustion chamber body 1. Therefore, an energy saving effect can be expected.

[0061] Since a plurality of guide pipes 115 are arranged radially in the space 111, the steam is also guided to the upper turbine 130 on the outlet 111b side by the inlet 111a force of the space 111, and the steam and Exhaust works reliably.

Further, even if the exhaust gas passing through the guide pipe 115 is hot, the water in the cooling passage 114 remains in the guide pipe. Since 115 is cooled, deformation of the guide tube 115 and the blades 131 of the upper turbine 130 that may be caused by the heat of the exhaust can be prevented. 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 water vapor having a specific gravity smaller than that of the water moves to the axial center side, and the guide tube It flows out from 115.

Further, water also flows into 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 steam is generated inside and outside the guide tube 115 and this steam is sent to the blades 131 of the upper turbine 130, the upper turbine 130 can efficiently apply the rotational force to the combustion chamber body 1.

Further, the water having the equal force 118 and flowing into the guide pipe 115 and having been able to evaporate in the guide pipe 115 collides with the blades 131 of the upper turbine 130 and evaporates.

[0062] Further, water vapor and exhaust gas 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 of this injection. Therefore, this also enables the combustion chamber body 1 to 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.

<o

In the lower water vapor outlet 120, the water vapor is taken out from the through hole 121 that is the water vapor outlet 120. At this time, the water vapor flowing out of 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 cylindrical portion 10 and the lower surface plate 15. Thus, when the combustion product is combusted 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 1 need not be rotated by the combustion chamber body driving means 170. Also, the combustion chamber body 1 can be rotated.

[0064] Further, water vapor and exhaust gas from the jet port 152 of the lower turbine 150 are jetted to the lower stationary blade 155, and the combustion chamber body 1 is also rotated by the repulsive force of this jet. Therefore, this also enables the combustion chamber body 1 to be efficiently rotated by burning the combustion products in the combustion chamber body 1. Furthermore, the water W from the water supply unit 100 that has not evaporated in the combustion chamber body 1 is discharged through the water discharge hole 160. Therefore, there is no excess water W remaining in the combustion chamber body 1 and it does not adversely affect the combustion of the combusted material.

[0065] 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 1 is rotated by the combustion chamber body driving means 170 at an appropriate time. To stop. Further, when the rotational force of the combustion chamber body 1 by the upper turbine 130 and the lower turbine 150 is large, the rotational force is taken out via the gear device 170a and is generated by the generator. Therefore, the power from the combustion chamber body 1 can be taken out as electric power.

[0066] Water vapor and exhaust gas that passes through the upper turbine 130 and the lower turbine 150 of the combustion chamber body 1 and reaches 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 collection pipe 90 is centrifuged by the gas centrifuge 91 and separated for each type of gas. Among these, the water vapor is liquefied and stored in the water storage tank 101.

Further, a part of the gas recovered by the gas recovery pipe 90 is injected into the combustion chamber body 1 through the gas recirculation pipe 93. The oxygen injection nozzle 37 is provided inside the fluid injection nozzle 32. Since it is provided coaxially with 32, gas is also injected into the central force of the fluid. The gas injected from the oxygen injection nozzle 37 diffuses the fluid widely into the combustion chamber body 1, and the distribution of the fluid becomes uniform, and the combustion of the combustion material in the inner cylinder 20 is efficient. Can be done.

[0067] The ash generated in the combustion chamber body 1 falls to the lower part of the combustion chamber body 1, 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. It is led from the ash discharge passage 71 to the ash discharge 70. In this process, the ash content discharge passage portion 71 is cooled by the cooling water flowing through the cooling water passage 78.

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 75a 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 on the receiving part 73 side passes through the hole 75a together with the gas in the outer chamber body 50 from the hole 75a of the disk 75 on the receiving part 73 side, and the ash is discharged from the disk 75 on the receiving part 73 side. Ashes accumulate in the disk 75 on the mouth 70 side.

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 73 7 Ash and gas accumulated between the disk 75 on the 3 side and the disk 75 on the ash outlet 70 are discharged from the ash outlet 70. As a result, the ash can be extracted from the combustion device. In addition, the gas accumulated between the disk 75 on the receiving portion 73 side and the disk 75 on the ash content outlet 70 side has a high atmospheric pressure that is almost the same as that of the outer chamber body 50, and the ash is discharged together with this gas. As it goes out from exit 70, ash is discharged smoothly.

[0069] After that, 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 space between the disk 73 on the receiving part 73 side and the disk 75 on the ash content outlet 70 side is almost equal to the atmospheric pressure, so that gas enters the combustion chamber body together with ash from the outer chamber body 50. Some atmospheric pressure fluctuation occurs in 1. Due to this atmospheric pressure fluctuation, the ash that has solidified after being melted in the combustion chamber body 1 near the lower part can be crushed.

Since the cylindrical body 74 is normally closed by one of the pair of discs 75, the combustion chamber body 1 and the outside of the outer chamber body 50 do not communicate directly with each other via the outer chamber body 50. Compared with the case where a mechanism for opening and closing the state 74 is provided, the water recovery efficiency of the gas recovery pipe 90 can be improved because water vapor and exhaust gas are not exhausted from the ash outlet 70.

[0070] For example, when a combustible material such as asbestos or wood is input from the combustible material inlet 62, when the duct 61 is opened by the duct opening and closing mechanism 63, the combustible material goes down the duct 61 and from the upper opening 3 Placed in the combustion chamber body 1.

That is, when the shaft 66 rotates both the pair of discs 65 and the duct 61 is opened by the hole 64 of the disc 65 on the receiving portion 73 side, the disc 65 on the combustor inlet 62 side is opened. However, the duct 61 is closed, and the combustible material enters between the disc 65 on the upper bearing 56 side and the disc 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 upper bearing 5 The duct 61 is opened by the hole 64 of the disc 65 on the 6th side, and the combustible material between the disc 65 on the combustible inlet 62 side and the disc 65 on the upper side bearing 56 enters the combustion chamber body 1 from the upper opening 3 It is sent.

Thereby, the combustion product can be introduced into the combustion chamber body 1 from other than the fluid supply unit 30.

At this time, since the space between the disc 65 on the combustor inlet 62 side and the disc 65 on the upper bearing 56 side is almost equal to the atmospheric pressure, gas enters from the outer chamber body 50. As a result, some atmospheric pressure fluctuations in the combustion chamber body 1 occur. This 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.

[0072] Since the duct 61 is normally closed by one of the pair of discs 65, the combustion chamber body 1 and the outside of the outer chamber body 50 do not directly communicate with each other via the outer chamber body 50. Compared with the case where a mechanism for simply opening and closing the duct 61 is provided, the upper side bearing 56 does not discharge much water vapor or exhaust gas, so that the gas recovery efficiency of the gas recovery pipe 90 can be improved.
