[0021] There is a gap between the outer furnace 2 and the inner furnace 3, and the gap is used for gas flow and sufficient oxygen is provided for the internal fuel to burn;

[0022] The bottom of the outer furnace 2 is provided with a through slot for use with the air supply system 4;

[0023] The air supply system 4 includes a heat-insulating mounting base plate 41 placed at the bottom of the combustion furnace shell 1, a heat-insulating cover shell 42 riveted on the heat-insulating mounting base plate 41, an electric-controlled blower 43 placed in the heat-insulating cover shell 42 and mounted on the heat-insulating mounting base plate 41, and a transfer groove 44 placed at the end of the heat-insulating cover shell 42 and connected to the heat-insulating cover shell 42 at one end and connected to the through groove at the other end;

[0024] The air outlet of the electric blower 43 is arranged corresponding to one side of the transfer slot 44, so as to ensure that the air blown by the electric blower 43 can flow into the transfer slot 44 along the heat insulation cover 42, and flow into the through slot through the transfer slot 44, and enter the furnace inner tank and the furnace outer tank;

[0025] In order to effectively isolate the heat and ensure that the internal electric-controlled blower 43 will not be affected by the heat, the heat-insulating cover 42 is of a U-shaped structure, which includes an inner heat-insulating cover 421 covering the electric-controlled blower 43, an outer heat-insulating cover 422 placed outside the inner heat-insulating cover 421, and heat-insulating cotton 423 placed between the inner heat-insulating cover 421 and the outer heat-insulating cover 422; an insulation space is formed between the heat-insulating cover 42 and the heat-insulating installation base plate 41, and the ambient temperature of the space is 30 to 60°C.
