[0022] In this embodiment: when the fuel is burning, the motor 2 is started, and the motor 2 drives the driving rotating rod 20 fixedly connected to the output end to rotate. The rotating driving rotating rod 20 will drive the chain 6 meshed with the outer side to rotate along the guide plate 5 to one end, thereby driving the first supporting ring plate 21 provided above the chain 6 and the second supporting ring plate 23 slidingly connected to the first supporting ring plate 21 to rotate from the bottom of the feed hopper 8 to the middle of the combustion chamber 2. At this time, the fuel blocks in the feed hopper 8 will fall into the grooves between a group of first supporting ring plates 21 and the grooves on the upper surface of the second supporting ring plate 23 during the movement of the chain 6. The moving chain 6 drives the first supporting ring plate 21 and the second supporting ring plate 23 to drive the fuel blocks that fall into the grooves to move to the middle of the combustion chamber 2, and then ignite the fuel blocks. , start the blower, and the wind blown by the blower enters the first supporting ring plate 21 and the second supporting ring plate 23 through the air supply chamber 7 and the air holes 24 opened on the surface of the air supply chamber 7. The air flow passes through the air inlet holes opened on the surfaces of the first supporting ring plate 21 and the second supporting ring plate 23 and flows into the fuel blocks supported by the surfaces of the first supporting ring plate 21 and the second supporting ring plate 23. The fuel blocks are on the stepped supporting platform formed by the first supporting ring plate 21 and the second supporting ring plate 23, which increases the contact area between the fuel blocks and the air flow, thereby improving the combustion efficiency of the fuel blocks. When the ash of the burned fuel blocks moves to one end of the inner side of the combustion chamber 2 under the transportation of the chain 6, it falls onto the surface of the guide plate 1 under the action of gravity, and follows the inclined angle of the guide plate 13 to the lower end of the inner side of the combustion chamber 2, completing the combustion process.
