The bottom of the inner fire cover 8 is fixedly communicated with an ash discharge pipe 15. The top end of the ash discharge pipe 15 extends to the inner bottom wall of the inner fire cover 8. The bottom end of the ash discharge pipe 15 extends downward and outward and penetrates the outer wall of the base 1. The outer wall of the bottom of the support shaft 9 is fixedly connected with a large gear 12. There is a motor 1 13 at the rear side of the base 1. There is a reducer 14 at the front side of the motor 1 13. The output shaft of the motor 1 13 is fixedly connected with the input shaft of the reducer 14. The top end of the output shaft of the reducer 14 is fixedly connected with a small gear 30. The small gear 30 meshes with the large gear 12. The inside of the fuel cylinder 2 has three air ducts 16. The three air ducts 16 are arranged in parallel. The two ends of the three air ducts 16 are rotatably connected with the outer wall of the fuel cylinder 2. The outer wall of the air duct 16 is fixedly communicated with a plurality of short pipes 17. The short pipes 17 are distributed equidistantly left and right in a cross shape. The right outer wall of the fuel cylinder 2 is fixedly connected with three motors 2 18. The output shafts of the three motors 2 18 are respectively fixedly connected with the right ends of the three air ducts 16. The right ends of the three air ducts 16 penetrate the outer wall of the fuel cylinder 2. The inner wall of the combustion cylinder 3 is fixedly connected with refractory bricks 19. The outer wall of the combustion cylinder 3 is fixedly sleeved with two connecting pipes 20 distributed up and down. The inner side wall of the connecting pipe 20 is provided with uniformly distributed air injection holes 21. The air injection holes 21 penetrate the combustion cylinder 3 and the refractory bricks 19.

[0021] The front side of the base 1 is provided with a bellows 22, the front side wall of the bellows 22 is open, and the rear side wall of the bellows 22 is fixedly connected to two blowing pipes 23, the rear ends of the blowing pipes 23 penetrate the base 1 and extend to the bottom of the rotating grate 10, and the left and right side walls of the bellows 22 are respectively fixedly connected with ventilation pipe 25 and ventilation pipe 1 24, the ventilation pipe 1 24 is respectively connected to the upper and lower connecting pipes 20 through a tee pipe, and the ventilation pipe 2 25 is rotatably connected and connected to the three air pipes 16 through a cross joint.

[0022] An ignition port 26 is provided on the front side wall of the combustion tube 3 , and a furnace door 31 is rotatably connected to the front end of the ignition port 26 .

The front side wall and the rear side wall of the top cover 5 are respectively fixedly connected with a water inlet pipe 27 and a water outlet pipe 29, and the water inlet pipe 27 and the water outlet pipe 29 are connected to the cavity of the top cover 5.

[0024] The hot flue gas will first rise into the chimney 4, and cold water will enter the cavity of the top cover 5 from the water inlet pipe 27, and then enter the cavity of the chimney 4 through the circulation pipe 28. After heat exchange with the hot flue gas, the temperature of the cold water rises to warm water, and then enters the boiler from the water outlet pipe 29 to improve the utilization rate. Ignition is carried out from the ignition port 26, and the furnace door is closed after ignition to ensure the stability of the combustion process. The front end opening of the bellows 22 is connected to an external fan to transport air into the bellows 22. This part of the air enters the connecting pipe 20 through the ventilation pipe 24, and then blows air into the combustion tube 3 from the blowing hole 21, enhancing the air circulation in the combustion tube and promoting the full combustion of the fuel.

[0025] At the same time, another part of the air enters the three air ducts 16 through the ventilation pipe 25, and is blown through the short pipe 17 and the blowing pipe 23, which can get sufficient oxygen supply to ensure sufficient combustion and further improve the combustion efficiency.

The bundled straw is dried in the upper part of the air duct 16. When the straw on the outer surface is dried, the motor 2 18 is started to drive the air duct 16 to rotate. The three air ducts 16 rotate in the same direction. These rotating air ducts 16 drive the short tubes 17 fixed thereon to effectively separate the bundled straw layer by layer, and then fall to the upper part 10 for combustion, so that the air can contact the fuel more evenly, thereby improving the combustion efficiency.

[0027] When it is necessary to discharge ash, start the motor 13, which drives the small gear to rotate through the reducer 14, and the small gear meshes with the large gear 12, thereby driving the support shaft 9 and the rotating grate 10 to rotate.

[0028] The function of the combination of the air duct 16 and the short pipe 17 is as follows: First, the rotation of the first air duct 16 can cause the short pipe 17 to rotate together, and the short pipe 17 can play the role of gradually decomposing the bundled straw layer by layer; Second, the air outlet of the short pipe 17 can help the external combustion of the bundled straw, thus forming the function of drying the straw. After drying the straw, rotate the first air duct 16, and the dried straw can be transferred to the rotary grate 10 through the short pipe 17 for combustion.

[0029] The outer wall of the rotary grate 10 is in clearance fit with the inner side wall of the inner fire cover 8. The scraper 11 fixed thereon will scrape the ash accumulated inside the inner fire cover 8 into the ash discharge pipe 15 as the rotary grate 10 rotates, and finally discharge it outside the equipment.
