Description

Technical Field

[0001] This invention relates to the field of gas generator technology, specifically a multi-structure collaborative biomass gas generator. Background Technology

[0002] A biomass gas generator is a device that converts biomass (such as wood, crop straw, biogas, etc.) into combustible gases (such as syngas, methane, etc.) through thermochemical or biochemical processes. The generated gas can be used for power generation, heating, or as a fuel to replace fossil fuels.

[0003] In the gasification process, in order to ensure that the raw materials react fully, it is usually necessary to spread the raw materials evenly. Spreading evenly can avoid the airflow "short circuit" (where the local resistance is too small, causing the gas to concentrate and pass through), and ensure that the gasifying agent (air / steam) is in full contact with the raw materials.

[0004] To address this, the accumulated raw materials can be evenly spread in the combustion chamber by pushing. After the combustion of the raw materials is completed, the ash residue needs to be treated. In the existing technology, the machine is usually stopped and cooled after the reaction is completed, and the ash discharge port is opened to discharge the ash after cooling.

[0005] However, this method requires reheating the combustion chamber after ash removal, which greatly wastes energy and reduces the biomass gasification rate.

[0006] To address this, a bar grate can be installed at the bottom of the combustion chamber for continuous ash removal. The grate is driven by a motor to rotate slowly, allowing for periodic or continuous ash removal. However, since biomass gasification itself requires high temperatures, continuous ash removal via the grate exposes the combustion chamber to the external environment, inevitably leading to heat loss within the combustion chamber. This necessitates more energy to support the reaction temperature, and the grate's prolonged exposure to high temperatures also shortens its lifespan. Summary of the Invention

[0007] The purpose of this invention is to provide a multi-structure collaborative biomass gas generator to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A multi-structure synergistic biomass gas generator, comprising:

[0010] Combustion chamber, and gasification chamber fixed on and connected to combustion chamber, wherein a guide plate is fixed in gasification chamber, and a partition and a fixing plate are fixed in combustion chamber, and multiple discharge slots are formed on the partition in an equidistant manner;

[0011] Also includes:

[0012] A pushing mechanism is provided on the fixed plate. The pushing mechanism includes a push plate. A guiding switching mechanism is provided in the combustion chamber. The guiding switching mechanism can switch the push plate to a spreading state or a slag removal state when the pushing mechanism drives the push plate to move in the horizontal direction.

[0013] A flow control mechanism is provided on the partition plate, including a blocking plate that cooperates with the discharge channel. The flow control mechanism can adjust the flow state of the discharge channel through the blocking plate when the pushing mechanism moves.

[0014] As a further aspect of the present invention: the pushing mechanism includes a cylinder fixed in the combustion chamber, and a support sleeve that is slidably connected to the push plate is fixed at the telescopic end of the cylinder. A first through groove and a second through groove are formed on the support sleeve, and a limiting post that passes through the first through groove is fixed on the push plate.

[0015] As a further embodiment of the present invention: the pushing mechanism further includes a first limiting plate and a second limiting plate respectively fixed to the support sleeve and the push plate, the first limiting plate and the second limiting plate are fixed with protruding columns, and a first spring is sleeved on the protruding column, the two ends of the first spring abutting against the first limiting plate and the second limiting plate respectively.

[0016] As a further embodiment of the present invention: the guiding switching mechanism includes a guide groove formed on the inner wall of the combustion chamber, the limiting post is slidably engaged with the guide groove, and a first guide rod, a second guide rod, and a third guide rod are rotatably mounted in the combustion chamber.

[0017] As a further embodiment of the present invention: the guiding switching mechanism further includes a first fixing block, a second fixing block, a third fixing block, and a fourth fixing block fixed in the combustion chamber, wherein the first fixing block abuts against the first guide rod, the second fixing block and the third fixing block abut against the second guide rod, and the fourth fixing block abuts against the third guide rod.

[0018] As a further embodiment of the present invention: the conduction control mechanism includes a sliding plate slidably mounted on the partition plate, a limiting groove is formed on the sliding plate, a first slot is formed on the partition plate, a first movable rod passing through the limiting groove is slidably mounted in the first slot, a movable plate is fixed to the end of the first movable rod, and the movable plate is fixedly connected to the sealing plate.

[0019] It also includes a follower component and an elastic component disposed on the first movable rod and connected to the limiting post.

[0020] As a further embodiment of the present invention: the follower component includes a support plate fixed on the first movable rod, a second movable rod fixed on the support plate, a first follower plate fixed at the end of the second movable rod, a second follower plate fixed on the first follower plate, and the first follower plate and the second follower plate abutting against the limiting post.

[0021] As a further embodiment of the present invention: the elastic component includes a second spring sleeved on the first movable rod, the two ends of the second spring abutting against the support plate and the partition plate respectively, and a third spring sleeved on the second movable rod, the two ends of the third spring abutting against the support plate and the first follower plate respectively.

[0022] As a further embodiment of the present invention: a symmetrically arranged conveyor roller is rotatably mounted in the combustion chamber, and a conveyor chain plate is sleeved on the conveyor roller.

[0023] As a further embodiment of the present invention: a blower is fixed on the combustion chamber, and an air duct connected to the combustion chamber is connected to the blower.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: The present application can switch the working state of the pusher plate in confined and high-temperature environments by means of the cooperation of the pushing mechanism and the guiding switching mechanism. Specifically, when the raw material is transported to the combustion chamber and accumulates on the baffle plate, the pusher plate performs a spreading action on the raw material under the action of the pushing mechanism and the guiding switching mechanism to ensure more complete combustion and gas production. After the raw material is burned, the pusher plate is controlled to switch to the slag removal state under the action of the guiding switching mechanism to treat the ash remaining after the raw material combustion. In addition, under the action of the pushing mechanism, the conduction state of the discharge trough can also be adjusted by the conduction control mechanism to ensure that the ash is discharged smoothly.

[0025] By combining the limiting post and the guide groove, the distance between the push plate and the partition can be adaptively adjusted when the push plate moves in the horizontal direction. This achieves the effect of uniformly spreading the raw material before combustion and removing the slag from the residual ash after combustion. In the entire process, the support sleeve can be moved in the horizontal direction by controlling the cylinder, avoiding the problems of inconvenience in installation and easy damage due to high temperature that occur when using other drive sources in confined and high-temperature environments.

[0026] When the position of the limiting column changes, the working state of the push plate can be adjusted. At the same time, according to the working state of the push plate, the cooperation state between the sealing plate and the discharge trough can be controlled. In this way, through the action of the limiting column, the first follower plate and the second follower plate, the baffle can be kept in a fully sealed state during the raw material spreading and combustion process. When the raw material is burned and slag is discharged, the sealing plate is automatically misaligned with the discharge trough to ensure that the residual ash can be discharged smoothly.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0041] Please see Figures 1-11 In this embodiment of the invention, a multi-structure synergistic biomass gas generator includes:

[0042] Combustion chamber 1, and gasification chamber 5 fixed on and connected to combustion chamber 1, wherein a guide plate 8 is fixed in gasification chamber 5, and a partition plate 9 and a fixing plate 10 are fixed in combustion chamber 1, wherein a plurality of discharge slots 901 are formed on the partition plate 9 in an equidistant distribution.

[0043] Also includes:

[0044] A pushing mechanism is provided on the fixed plate 10. The pushing mechanism includes a push plate 22. A guiding switching mechanism is provided in the combustion chamber 1. The guiding switching mechanism can switch the push plate 22 to a paving state or a slag removal state when the pushing mechanism drives the push plate 22 to move in the horizontal direction.

[0045] A flow control mechanism is provided on the partition 9, including a blocking plate 27 that cooperates with the discharge trough 901. The flow control mechanism can adjust the flow state of the discharge trough 901 through the blocking plate 27 when the pushing mechanism moves.

[0046] The combustion chamber 1 is rotatably mounted with symmetrically arranged conveyor rollers 11, and conveyor chain plates 12 are sleeved on the conveyor rollers 11.

[0047] A support 2 is fixed to the side of the combustion chamber 1, and a hopper 3 is fixed on the support 2. A screw conveyor 4 connected to the gasification chamber 5 is installed on the hopper 3. The screw conveyor 4 is used to transport the raw materials in the hopper 3 to the gasification chamber 5.

[0048] Specifically, the baffle 9 divides the combustion chamber 1 into two cavities. The upper cavity is connected to the gasification chamber 5 and is used for burning raw materials. The lower cavity is used to collect the ash produced after the raw materials are burned. When the raw materials in the hopper 3 are conveyed to the gasification chamber 5 by the screw conveyor 4, the guide plate 8 is inclined, causing the raw materials to enter the combustion chamber 1 and collect on the baffle 9. After the raw materials are conveyed, the blocking plate 27 and the discharge trough 901 are engaged by the control mechanism. At this time, the pushing mechanism works and drives the push plate 22 to move radially along the baffle 9. Under the action of the guide switching mechanism, the push plate 22 is in a spreading state to evenly spread the accumulated raw materials on the baffle 9, thereby ensuring that the raw materials can be fully burned. After spreading is completed, the pushing mechanism and the guide switching mechanism... Under the action of the mechanism, the pusher plate 22 is positioned at the end of its stroke towards the fixed plate 10. At this time, the raw material can be ignited. Under the conditions of high temperature and limited oxygen, the raw material is converted into syngas mainly composed of CO, H2, and CH4, and transported to the required position through the gasification chamber 5. After the raw material is burned, the ash remaining on the partition plate 9 is left. In response, the pushing mechanism continues to move, and under the action of the guiding switching mechanism, the pusher plate 22 is in the slag removal state. At the same time, the pushing mechanism will also drive the conduction control mechanism to move, so that the blocking plate 27 and the discharge trough 901 are in a misaligned state. Under the action of the pusher plate 22, the ash remaining on the partition plate 9 is discharged through the discharge trough 901 into the cavity below the combustion chamber 1 and falls onto the conveyor chain plate 12. Under the action of the conveyor roller 11, the ash is discharged from the combustion chamber 1 through the conveyor chain plate 12.

[0049] Please see Figures 1-4 , Figures 7-9 The pushing mechanism includes a cylinder 20 fixed in the combustion chamber 1. The telescopic end of the cylinder 20 is fixed with a support sleeve 21 that is slidably connected to the push plate 22. A first through groove 2101 and a second through groove 2102 are formed on the support sleeve 21. A limiting post 24 that passes through the first through groove 2101 is fixed on the push plate 22. The pushing mechanism also includes a first limiting plate 2103 and a second limiting plate 2201 fixed on the support sleeve 21 and the push plate 22, respectively. A protruding post is fixed on the first limiting plate 2103 and the second limiting plate 2201. A first spring 23 is sleeved on the protruding post. The two ends of the first spring 23 abut against the first limiting plate 2103 and the second limiting plate 2201, respectively.

[0050] Please see Figure 4 , Figure 5 The guiding switching mechanism includes a guide groove formed on the inner wall of the combustion chamber 1. The limiting post 24 is slidably engaged with the guide groove. A first guide rod 13, a second guide rod 14, and a third guide rod 15 are rotatably installed in the combustion chamber 1. The guiding switching mechanism also includes a first fixing block 16, a second fixing block 17, a third fixing block 18, and a fourth fixing block 19 fixed in the combustion chamber 1. The first fixing block 16 abuts against the first guide rod 13. The second fixing block 17 and the third fixing block 18 abut against the second guide rod 14. The fourth fixing block 19 abuts against the third guide rod 15.

[0051] A blower 6 is fixed on the combustion chamber 1, and an air duct 7 connected to the combustion chamber 1 is connected to the blower 6.

[0052] Please see Figure 5 In detail, the guide groove can be divided into six sections, namely the first straight groove 101, the first inclined groove 102, the second straight groove 103, the second inclined groove 104, the third straight groove 105, and the third inclined groove 106. The first straight groove 101, the second straight groove 103, and the third straight groove 105 are arranged in parallel, and the distance between them and the partition plate 9 decreases sequentially. One end of the first inclined groove 102 is connected to one end of the second straight groove 103, and the other end is connected to the first straight groove 101. One end of the second inclined groove 104 is connected to one end of the third straight groove 105, and the other end is connected to the second straight groove 103. The two ends of the third straight groove 105 are connected to the first straight groove 101 and the third straight groove 105 respectively, and are arranged in a cross shape with the second straight groove 103. In the horizontal direction, the third inclined groove 106 is located between the first inclined groove 102 and the second inclined groove 104.

[0053] Torsion springs are fitted on the rotating shafts of the first guide rod 13, the second guide rod 14, and the third guide rod 15. Under the action of the torsion springs, in the initial state, the first guide rod 13 abuts against the first fixing block 16, the second guide rod 14 abuts against the second fixing block 17, and the third guide rod 15 abuts against the fourth fixing block 19.

[0054] Please see Figure 4 , Figure 8 In the initial state, the limiting post 24 is located at the end of the stroke of the first straight groove 101 near the fixed plate 10, so that the size of the push plate 22 and the support sleeve 21 fitting together is maximized, so that the distance between the first limiting plate 2103 and the second limiting plate 2201 is maximized. The elongation of the first spring 23 in its natural state is greater than this distance. Therefore, the first spring 23 is in a pre-compressed state and always provides the push plate 22 with a thrust to move inward toward the support sleeve 21. At this time, the distance between the push plate 22 and the partition plate 9 is maximized, and this distance is the required spreading thickness of the raw material.

[0055] When it is necessary to burn raw materials to produce gas, the raw materials can be transported into the gasification chamber 5. Under the action of the guide plate 8, the raw materials fall onto the partition plate 9 and gradually accumulate. After the raw material is transported, the cylinder 20 pushes the support sleeve 21 to move away from the fixed plate 10, thereby driving the push plate 22 to move. This causes the limiting post 24 to slide within the first straight groove 101. Under the action of the limiting post 24 and the first straight groove 101, the height of the push plate 22 remains unchanged. When the limiting post 24 moves to the position of the first guide rod 13, the limit plate 22 continues to move. The first guide rod 13 is driven to move away from the first fixed block 16, so that the limiting post 24 always slides along the first straight groove 101. When the limiting post 24 separates from the first guide rod 13, the first guide rod 13 is reset under the action of the torsion spring. At this time, the push plate 22 abuts against the piled raw material and can spread the piled raw material so that the raw material is evenly spread on the partition plate 9 with the same thickness. When the limiting post 24 moves to the end of the stroke of the first straight groove 101 away from the fixed plate 10, the push plate 22 completes the spreading of the raw material.

[0056] Subsequently, cylinder 20 controls the support sleeve 21 to reset and drives push plate 22 to reset, causing the limiting post 24 to slide along the first straight groove 101 again. When the limiting post 24 moves to abut against the other side of the first guide rod 13, the first guide rod 13 cannot rotate because it abuts against the first fixed block 16. Therefore, under the action of the first guide rod 13, the limiting post 24 is controlled to disengage from the first straight groove 101 and enter the first inclined groove 102, causing push plate 22 to move away from the support sleeve 21, thereby reducing the distance between the first limiting plate 2103 and the second limiting plate 2201, thus compressing the first spring 23. As the limiting post 24 continues to move, it will disengage from the first inclined groove 102 and slide along the second straight groove 103. When the limiting post 24 abuts against one side of the second guide rod 14, the second guide rod 14 will abut against the second fixed block 16. The fixed block 17 separates and rotates toward the third fixed block 18 until it abuts against the third fixed block 18. Under the action of the second guide rod 14, it blocks the third inclined groove 106, preventing the limiting post 24 from entering the third inclined groove 106. When the limiting post 24 separates from the second guide rod 14, the second guide rod 14 is reset under the action of the torsion spring. When the limiting post 24 abuts against one side of the third guide rod 15, the third guide rod 15 moves away and moves away from the fourth fixed block 19, allowing the limiting post 24 to slide smoothly along the second straight groove 103. When the limiting post 24 separates from the third guide rod 15, the third guide rod 15 is also reset under the action of the torsion spring. When the limiting post 24 moves to the end of the stroke of the second straight groove 103 toward the fixed plate 10, the cylinder 20 stops moving, the support sleeve 21 is reset, and the position of the push plate 22 no longer changes.

[0057] At this time, the raw material in the combustion chamber 1 can be ignited and burned. Under the action of the blower 6, an appropriate amount of oxygen is introduced into the combustion chamber 1 through the air duct 7, so that the raw material burns and produces gas under limited oxygen. The generated gas will be discharged through the gasification chamber 5. When the raw material is completely burned, the remaining ash remains on the partition plate 9. At this time, the ash needs to be processed. Under the action of the cylinder 20, the support sleeve 21 is controlled to move again, thereby driving the push plate 22 to move, so that the limiting post 24 slides along the second straight groove 103 again. When the limiting post 24 moves to abut against the other side of the third guide rod 15, since the third guide rod 15 abuts against the fourth fixing block 19, the third guide rod 15 abuts against the fourth fixing block 19, so that ... Rod 15 stops moving and guides the limiting post 24 into the second inclined groove 104, thereby driving the push plate 22 to move away from the support sleeve 21. During this process, the limiting post 24 will also control the blocking plate 27 to be misaligned with the discharge groove 901 through the conduction control mechanism. When the limiting post 24 leaves the second inclined groove 104 and enters the third straight groove 105, the push plate 22 just moves to the position of contact with the partition 9. Under the action of the push plate 22, the ash remaining on the partition 9 is pushed through the discharge groove 901 into the lower cavity of the combustion chamber 1 and falls onto the conveyor chain plate 12. Under the action of the conveyor roller 11, the conveyor chain plate 12 is controlled to move so as to discharge the ash from the combustion chamber 1.

[0058] When the limiting post 24 moves to the end of its stroke on the side of the third straight groove 105 away from the fixed plate 10, the ash on the partition plate 9 is discharged. At this time, the cylinder 20 controls the support sleeve 21 to reset and controls the limiting post 24 to slide in the opposite direction along the third straight groove 105. When the limiting post 24 moves to the position where the third straight groove 105 and the third inclined groove 106 are connected, the first spring 23 is released elastically and drives the push plate 22 to move toward the support sleeve 21, so that the limiting post 24 disengages from the third straight groove 105 and enters the third inclined groove 106. During this process, the limiting post 24 is not obstructed and enters the first straight groove 101 along the third inclined groove 106 until the limiting post 24 returns to the end of its stroke on the side of the first straight groove 101 toward the fixed plate 10. The above steps are repeated to achieve the spreading of raw materials and the treatment of ash after combustion.

[0059] Preferably, by cooperating with the limiting post 24 and the guide groove, the distance between the push plate 22 and the partition plate 9 can be adaptively adjusted when the push plate 22 moves in the horizontal direction, thereby achieving the effect of uniformly spreading the raw material before combustion and removing the slag from the residual ash after the raw material is burned. In the entire process, the support sleeve 21 can be moved in the horizontal direction by controlling the cylinder 20, avoiding the problems of inconvenient installation and easy damage due to high temperature that occur when using other drive sources in confined and high-temperature environments.

[0060] Please see Figure 4 , Figures 6-8 , Figure 10 , Figure 11 The conduction control mechanism includes a sliding plate 33 slidably mounted on the partition 9, a limiting groove 3301 formed on the sliding plate 33, a first slot 902 formed on the partition 9, a first movable rod 25 slidably mounted in the first slot 902, passing through the limiting groove 3301, a movable plate 26 fixed to the end of the first movable rod 25, and the movable plate 26 fixedly connected to the sealing plate 27; it also includes a follower component and an elastic component disposed on the first movable rod 25 and connected to the limiting post 24, the follower component including a support plate 28 fixed on the first movable rod 25, and the... A second movable rod 30 is fixed on the support plate 28. A first follower plate 32 is fixed to the end of the second movable rod 30. A second follower plate 3201 is fixed on the first follower plate 32. The first follower plate 32 and the second follower plate 3201 abut against the limiting post 24. The elastic component includes a second spring 29 sleeved on the first movable rod 25. The two ends of the second spring 29 abut against the support plate 28 and the partition plate 9, respectively. A third spring 31 is sleeved on the second movable rod 30. The two ends of the third spring 31 abut against the support plate 28 and the first follower plate 32, respectively.

[0061] Furthermore, the elongation of the second spring 29 in its natural state is greater than the length of the first movable rod 25. Therefore, the second spring 29 is in a pre-compressed state and always provides a thrust to the support plate 28 in the direction away from the partition plate 9. When the distance between the support plate 28 and the fixed plate 10 is the smallest, the distance between the first follower plate 32 and the fixed plate 10 reaches the maximum. The elongation of the third spring 31 in its natural state is also greater than this distance. Therefore, the third spring 31 is also in a pre-compressed state and always provides a thrust to the first follower plate 32 in the direction away from the fixed plate 10.

[0062] Please see Figure 7 In the initial state, the sealing plate 27 and the discharge groove 901 cooperate with each other, so that the partition 9 forms an integral plane. At this time, the first movable rod 25 is located at the end of the stroke of the first slot 902 away from the fixed plate 10, and under the action of the sliding plate 33 and the limiting groove 3301, the first movable rod 25 always remains perpendicular to the partition 9. The second movable rod 30 is located at the end of the stroke of the second slot 1001 away from the partition 9. When the limiting post 24 is located at the end of the stroke of the first straight groove 101 facing the fixed plate 10, it just abuts against the first follower plate 32. When the limiting post 24 slides along the first straight groove 101 and the push plate 22 performs the paving action, the limiting post 24 and the second follower plate 3201 are separated. When the push plate 22 completes the paving and the limiting post 24 moves to the end of the stroke of the second straight groove 103 facing the fixed plate 10, the raw material can be burned to produce gas.

[0063] After the raw material combustion is complete, the limiting column 24 continues to move and enters the second inclined groove 104 through the second straight groove 103. During this process, the limiting column 24 will abut against the second follower plate 3201 and drive the second follower plate 3201 to move towards the partition plate 9. This will cause the first follower plate 32 to drive the second movable rod 30 to slide along the second slot 1001. The second movable rod 30 will also drive the support plate 28 to move, causing the second spring 29 to be compressed. This will cause the sealing plate 27 to move away from the gasification chamber 5 through the first movable rod 25 and the movable plate 26. When the sealing plate 27 is completely separated from the discharge groove 901, the sealing plate 27 is in the horizontal direction. The upper part is no longer restricted. At this time, the third spring 31 is released elastically and drives the second movable rod 30 to move through the first follower plate 32, so that the support plate 28 moves toward the fixed plate 10, so that the first movable rod 25 slides along the first slot 902 and drives the sliding plate 33 to move through the limiting slot 3301. The first movable rod 25 also drives the sealing plate 27 to move through the movable plate 26 until the first movable rod 25 moves to the end of the stroke of the first slot 902 facing the fixed plate 10. At this time, the sealing plate 27 is located below the partition 9 and is just between the two discharge slots 901, so that the sealing plate 27 and the discharge slot 901 are in a misaligned state.

[0064] At this time, when the push plate 22 moves, the ash remaining on the partition plate 9 can be pushed onto the conveyor chain plate 12 through the discharge groove 901 to clean the impurities in the combustion chamber 1. After cleaning, the limiting post 24 will return to the first straight groove 101 through the third inclined groove 106. During this process, the limiting post 24 will abut against the first follower plate 32 and push the first follower plate 32 to move towards the fixed plate 10, thereby driving the support plate 28 to move through the second movable rod 30, causing the first movable rod 25 to move. The first movable rod 25 will drive the sealing plate 27 to move through the movable plate 26 until the sealing plate 27 moves to the position that matches the discharge groove 901. Then, the second spring 29 is released elastically, causing the first movable rod 25 to reset, so that the sealing plate 27 returns to the discharge groove 901 and seals the discharge groove 901 again.

[0065] Preferably, when the position of the limiting post 24 changes, the working state of the push plate 22 can be adjusted. At the same time, according to the working state of the push plate 22, the cooperation state between the sealing plate 27 and the discharge trough 901 can be controlled. In this way, under the action of the limiting post 24, the first follower plate 32 and the second follower plate 3201, the partition plate 9 can be kept in a fully sealed state during the raw material spreading and combustion process. When the raw material is burned and slag is discharged, the sealing plate 27 is automatically misaligned with the discharge trough 901 to ensure that the residual ash can be discharged smoothly.
