This kind of traditional combustion method, flame spread along the natural flow direction of hot flue gas during solid fuel burning, and combustion strength is high, and the firepower is flourishing, can satisfy user's cooking demand, and the shortcoming is that the volatile analysis goes out fast, produces a large amount of black cigarettes.
The reverse combustion stove has the advantages of high stove temperature, full combustion, low particle emission concentration, suitability for high-volatile fuels such as bituminous coal and the like, and suitability for heating.

The problems of insufficient combustion and low burnout rate exist in both a forward combustion furnace and a reverse combustion furnace; at present, the fuel emission pollutants of the heating stove mainly comprise carbon monoxide, nitrogen oxides and smoke dust; for carbon monoxide, when the combustible gas concentration is low or the combustible gas leaves the high temperature combustion zone, there will be residual carbon monoxide when it does not reach sufficient combustion conditions. Therefore, the problem that the emission of carbon monoxide in the heating furnace exceeds the standard exists all the time;
the above-mentioned excessive emissions of carbon monoxide, nitrogen oxides and smoke dust cause the emissions not to meet the regulations of environmental protection requirements; however, the existing stove does not have the measures for reducing the pollutant emission, such as the blackness of smoke, smoke dust and SO, on the combustion mode2、NOx and CO2And the emission requirements of emission standards of atmospheric pollutants for boilers (latest version in 2018) cannot be met.
Meanwhile, it should be noted that most of heating stoves adopt manual deashing at present, however, most of manual deashing not only needs to consume operator's time, but also encounters the problem that the deashing effect is not good if the coal of part coal quality non-deformable appears, and the normal operation of heating and cooking is seriously influenced.
