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. Temperatures greater than 1000 o F. The cause of superheater and reheater ash corrosion depends on the fuel.

External corrosion in coal-fired boilers: Assessment from

Jan 01, 1981 · (1) External corrosion in coal-fired boilers 791 Thermodynamic calculations for this reaction and plant observations have both shown that hydrogen chloride is the only chlorine compound that is present in a significant quantity in the flue gas.9 The concentration of hydrogen chloride in the flue gas is thus directly related to the chlorine content of the coal and a typical coal containing 0.3 wt ~o of …
