The purpose of periodic soot blowing on the heating surface is to reduce the thermal resistance.

The hazards of boiler heating area ash include: affecting heat transfer, wasting fuel, and failing to reach the rated evaporation of boiler.

The main hazards of boiler heating area ash are:

1, the thermal efficiency of the boiler is reduced, because the thermal resistance of ash scale is 40 times that of steel, so the thermal efficiency of the boiler is greatly reduced;

2. The temperature of exhaust gas increases, which increases the heat loss;

3. Because the conduction efficiency of the heating surface is reduced, the boiler output is insufficient;

4. Due to the decrease of thermal efficiency, the exhaust temperature is high;

5, because the heating surface can't effectively transfer heat to the medium in the pot, the temperature of the furnace will rise and the coking of the furnace arch will be aggravated.
