The ventilation piece 22 and the inner wall of the inner shell 2 form an air distribution channel therebetween. The two ends of the air distribution channel are respectively connected with the inside of the smoke passing box 18 and the ash holding space.

[0063] Thus, the external air can enter the air distribution channel through the ash holding space and eventually enter the inside of the smoke passing box 18 to contact the flue gas, so that the combustible material in the flue gas is subjected to secondary combustion, the purposes of smoke elimination and combustion efficiency improvement are achieved, and the purpose of pollution reduction is achieved.

[0067] The flue gas generated by the coal combustion enters the flue, the external air enters the inside of the smoke passing box 18 through the air distribution channel, contacts the flue gas, and fully oxygenates, so that the combustible material in the flue gas is subjected to secondary combustion, the purposes of smoke elimination and combustion efficiency improvement are achieved, and the purpose of pollution reduction is achieved;

[0068] The ash of the coal after combustion can fall from the gap of the residue filtering part 7 to the ash holding space, and be cleaned by the ash cleaning drawer 29;

[0069] The new fuel and the ash are horizontally separated by the pusher device, which is superior to the traditional bottom-up combustion method of the stove, and there is no problem that the fuel is combusted on the top and the ash blocks the air from contacting the fuel below, and the flat push type feeding does not need to stir the combustion environment in the hearth during the ash cleaning stage, which can avoid the ash from being brought into the atmosphere due to the chimney negative pressure, and effectively solves the problem of excessive particulate matter emission during ash cleaning by the user.
