The motor 6 drives the gear 32 to mesh with the gear 27, which drives the crushing module 26 to crush and refine the fuel, so as to achieve the effect of complete combustion of the fuel. The crushed fuel enters the conveying pipe 8 through the feed pipe 29. The motor 7 drives the auger 28 to push the fuel to the feed pipe 1. 8. The fuel is fed into the combustion furnace 10 and burned above the grate 20. The heat generated by the combustion is converted into heat energy through a water-cooled circulation formed by the inlet pipe 14 and the outlet pipe 13. In addition, when the ash and slag after combustion accumulate at the bottom of the combustion furnace 10, the motor 3 12 drives the rotating shaft 19 to rotate the connecting plate 21. The spring 1 23 pushes the scraper 24 to scrape along the inner wall of the combustion furnace 10, pushing the ash and slag into the slag discharge pipe 22. Finally, the ash and slag fall into the collection box 16 in the slag discharge box 17. It can be cleaned regularly by the handle 15, which effectively avoids the accumulation of ash and slag and achieves the effect of automatic slag discharge.
