Adopt "steel ball dust removal" method
Boiler soot blowing:
Soot blowing is to keep the heating surface clean.
Because the thermal conductivity of ash is very small, the ash on the heating surface of the boiler affects the heat transfer of the heating surface, and the temperature of the heat absorbing working medium decreases and the exhaust temperature increases, thus reducing the thermal efficiency of the boiler;
When the ash deposition is serious, the cross-sectional area of flue gas flow decreases, the circulating resistance increases, the power consumption of induced draft fan increases, the operating load of boiler decreases, and even the boiler is forced to stop;
Due to dust accumulation, the smoke temperature in the rear part rises, which affects the safe operation of the rear heating surface.
Local dust accumulation is serious, which may form a "flue gas corridor". Due to the increase of flue gas velocity, the wear of local heating surfaces will increase.
Therefore, the boiler heating surface should be purged regularly.
