[0026] Example 1

[0027] A high-efficiency thermal power generation device, as described in a preferred embodiment of the present invention, is as follows: Figures 1-8As shown, the system includes a combustion furnace 1, a first shock absorber 101, a fine crushing box 2, a first rotating rod 3, a first crushing cylinder 4, a second crushing cylinder 401, a second rotating rod 5, a first pulley 6, a second pulley 7, a flat belt 8, a first motor 9, a load-bearing rod 10, a protective plate 11, an air preheater 12, a connecting seat 13, a second motor 14, adjustable fan blades 15, an economizer 1201, a second shock absorber 1202, a steam turbine body 16, a first exhaust pipe 17, a cover plate 18, a second exhaust pipe 19, a filter 20, a water-cooled pipe 21, a first frame 22, a second filter screen 23, a second frame 24, a first filter screen 25, a limiting plate 26, a dustproof plate 27, and a handle 28. The first shock absorber 101 is fixed to both the left and right sides of the outer wall of the combustion furnace 1. 01. The combustion furnace 1 is provided with the fine crushing box 2 on the front side. The economizer 1201 is embedded in the lower front part of the combustion furnace 1. The upper part of the economizer 1201 is connected to the lower part of the fine crushing box 2. The air preheater 12 is embedded in the front side of the economizer 1201. The second shock absorber 1202 is provided at the bottom of the economizer 1201. The turbine body 16 is installed in the middle of the top of the combustion furnace 1. The first exhaust pipe 17 is embedded in both the left and right sides of the turbine body 16. The outer end of the first exhaust pipe 17 is snapped with the cover plate 18. The second exhaust pipe 19 is embedded in both the left and right sides of the first exhaust pipe 17. The filter 2 is installed on the upper part of the second exhaust pipe 19. 0. The first rotating rod 3 is rotatably connected to the right side of the fine crushing box 2, and the first crushing cylinder 4 is installed on the first rotating rod 3. The second rotating rod 5 is rotatably connected to the left side of the fine crushing box 2, and the second crushing cylinder 401 is installed on the second rotating rod 5. The second crushing cylinder 401 is in contact with the first crushing cylinder 4. The first pulley 6 is provided at the front side of the first rotating rod 3, and the second pulley 7 is connected to the front side of the second rotating rod 5. The flat belt 8 is wound between the first pulley 6 and the second pulley 7. The protective plate 11 is welded to the outer wall of the fine crushing box 2. The load-bearing rod 10 is fixedly connected to the left side of the protective plate 11. The first motor 9 is bolted to the load-bearing rod 10. The output shaft is connected to the front end of the second rotating rod 5. The connecting seat 13 is welded to the bottom of the inner wall of the air preheater 12. The second motor 14 is installed on the connecting seat 13 by bolts. The adjustable fan blade 15 is rotatably installed on the output shaft of the second motor 14. The water-cooling pipe 21 is installed on the rear side of the inner wall of the combustion furnace 1. The first frame 22 is slidably placed on the upper part of the combustion furnace 1. The second filter screen 23 is connected to the inner side of the first frame 22. The second frame 24 is snapped onto the rear side of the air preheater 12. The first filter screen 25 is installed on the inner side of the second frame 24. The limiting plate 26 is provided on both the front and rear sides of the top of the combustion furnace 1. The dustproof plate 27 is placed on the upper part of the limiting plate 26.The handle 28 is welded to the center of the top of the dustproof plate 27.

[0028] When thermal power generation is required, workers first turn on the combustion furnace 1 and the air preheater 12. Then, workers put coal into the crushing box 2. The coal in the crushing box 2 slides into the combustion furnace 1 through the economizer 1201. The heat generated by the combustion furnace 1 burns the coal. The economizer 1201 can use the waste heat of flue gas to heat the feedwater, reducing coal consumption. The air preheater 12 draws outside gas into the economizer 1201, which blows the coal in the economizer 1201 into the combustion furnace 1 for complete combustion. At the same time, the air preheater 12 heats the air. The gas that is fully combusted in the combustion furnace 1 is discharged into the turbine body 16. The steam turbine body 16 converts the thermal energy of steam into mechanical energy. The gas inside the steam turbine body 16 is then forced into the first exhaust pipe 17. The gas in the first exhaust pipe 17 is then discharged into the filter 20 through the second exhaust pipe 19. The filter 20 filters the gas, thereby reducing air pollution. The first damping block 101 and the second damping block 1202 provide shock absorption. If the first exhaust pipe 17 is overloaded, the operator can open the cover plate 18, and some gas will be discharged from the second exhaust pipe 19. In this way, the equipment achieves efficient thermal power generation. When thermal power generation is not needed, the operator can shut down the combustion furnace 1 and the air preheater 12. To ensure more complete combustion of the coal, the operator can turn on the first motor 9. The rotation of the output shaft of the first motor 9 will drive the second rotating rod 5 to rotate. The rotation of the second rotating rod 5 will cause the second pulley 7 and the flat belt 8 to rotate. The flat belt 8 will cause the first pulley 6 and the first rotating rod 3 to rotate. The first crushing cylinder 4 and the second crushing cylinder 401 will then rotate. At this time, the operator can place the coal into the fine crushing box 2. The rotation of the first crushing cylinder 4 and the second crushing cylinder 401 will crush the coal into coal powder. The load-bearing rod 10 will support the first motor 9. The protective plate 11 can protect the first motor 9, the flat belt 8, and other components to prevent accidental contact by the operator. When it is not necessary to crush the coal into pulverized coal, the operator can simply turn off the first motor 9. If the operator needs to increase the gas intake of the air preheater 12, they can first pull the adjustable fan blades 15 outwards. Once the adjustable fan blades 15 are fully open, the operator can turn on the second motor 14. The rotation of the second motor 14 will cause the adjustable fan blades 15 to rotate, allowing the air preheater 12 to draw in a large amount of gas. When the operator needs to reduce the gas intake of the air preheater 12, they can push the adjustable fan blades 15 backwards. This allows the combustion speed to be adjusted according to power generation needs. Afterwards, the operator can turn off the second motor 14 and turn on the water-cooling pipe 21.The water-cooling pipe 21 removes the heat generated during combustion in the combustion furnace 1, preventing overheating. When cooling the combustion furnace 1 is not required, the water-cooling pipe 21 can be shut off. Unburned coal dust will be intercepted by the second filter screen 23 and will fall back into the combustion furnace 1 to continue burning. The first frame 22 provides support. When the second filter screen 23 needs cleaning, the first frame 22 can be removed from the combustion furnace 1, and the second filter screen 23 can be removed as well. After cleaning, the first frame 22 and the second filter screen 23 can be clipped back onto the combustion furnace 1, effectively reducing coal dust waste. In this situation, the second frame 24 provides support, and the first filter 25 filters out impurities from the outside air. When there are many impurities on the first filter 25, the worker can remove the second frame 24 and the first filter 25 for cleaning. After cleaning, the worker puts the second frame 24 and the first filter 25 back in place. The limiting plate 26 limits the dustproof plate 27, which protects the coal ash in the fine crushing box 2 and reduces its movement. When the worker needs to add coal, the worker can lift the handle 28, which will cause the dustproof plate 27 to detach from the limiting plate 26. At this time, the worker can add fine coal into the crushing box, and then the worker can use the handle 28 to put the dustproof plate 27 back in place.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
