[0043] It should be noted that this is convenient for disassembly and installation at any time, so as to replace and maintain the auger 120 and the driving assembly 130.

[0044] Further, the pipe diameter of the discharge section 111 is greater than that of the feeding section 112.

[0045] It should be understood that this is to avoid material blocking in the discharge section 111, and since the material fuel is in an ignited state, the pipe diameter is increased to increase the combustion space.

[0046] The above are only preferred embodiments of the present application, and do not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation made by using the content of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
