dew point corrosion coal mill. The outlet temperature of the coal mill is maintained at desired point so that the coal delivered from the mill is completely dry and achieves the desired temperature. Also, in case of high temperature at the mill outlet, cold air is blown in to reduce the risk of fire. 5.1.4.2 Discussion.

Fuel Ash Corrosion. Less than 300 o F. Dew-point corrosion occurs when sulfuric acid condenses. 500 o -750 o F. Waterwall-tube corrosion occurs in coal-fired units by the formation of pyrosulfates of sodium and potassium. In refuse-fired boilers, mixtures of chlorides of zinc, lead, iron and sodium are the likely causes of corrosion. More
