[0024] Working principle of this utility model:

[0025] The operation is similar to that of existing household heating stoves and cooking stoves such as wood stoves, coal pellet stoves, and coal-fired stoves. The difference is that the solid fuel burns in the inner combustion bladder 1. As the temperature is increased, the interlayer between the outside of the inner combustion bladder 1 and the furnace body shell 2 is also heated. According to the hot air principle, the hot air is discharged from the hot air outlet 5, so that the air at the bottom and the outside can easily enter the interlayer, thereby facilitating the outside air to enter the inner combustion bladder 1 through the air inlet 7, and the density of the air inlet 7 at the connecting flange 6 is greater than the density of the air inlet 7 on the side wall of the inner combustion bladder 1, which is more conducive to air entering from the connecting flange 6, providing sufficient air for the flame part, ensuring sufficient combustion by providing sufficient air, and facilitating rapid temperature increase. After temperature increase, it is conducive to the decomposition and gasification of the solid fuel, thereby further promoting more complete combustion and effectively reducing smoke. Especially after ignition and temperature increase, almost no black smoke can be seen. Not only can the fuel be effectively utilized, but the combustion is more complete, greatly reducing the generation of smoke, which is more conducive to environmental protection.
