Daily Question (January 10)

Soot blowing is done to keep the heated surfaces clean. Due to the very low thermal conductivity of ash, ash accumulation on the heating surfaces of the boiler affects heat transfer there, causing the temperature of the heat-absorbing fluid to drop and the exhaust gas temperature to rise, thereby reducing the boiler’s thermal efficiency ； When dust accumulation is severe, it reduces the cross-sectional area through which the flue gas flows, increasing flow resistance, raising the power consumption of the exhaust fans, decreasing the boiler’s operating load, and even forcing the boiler to shut down ； The accumulation of dust raises the temperature of the smoke at the rear, affecting the safe operation of the heating surfaces at the tail section. Severe local soot accumulation can create a \"flue gas corridor,\" leading to increased wear on the locally heated surfaces due to the higher flue gas velocity. Therefore, the heating surfaces of the boiler should be soot-blowed regularly.

When the heating surface of the boiler is severely fouled with ash or slag, it will cause the steam temperature to drop. The purpose of soot blowing is to prevent slagging and ash accumulation on the heated surfaces, improve the heat transfer efficiency of these surfaces, enhance the boiler’s thermal efficiency, and avoid situations where ash accumulated in the horizontal flues of the boiler cannot be removed and falls back into the furnace, causing the boiler to stop functioning. The soot blowing sequence starts from the furnace chamber and proceeds in the direction of the flue gas flow until the tail end. The soot blower operates in pairs.
