Low Temperature Corrosion in Boiler and Its Prevention

Condensation of these acids results in metal wastage and boiler tube failure, air preheater corrosion, and flue gas duct corrosion. In order to avoid or reduce the cold end corrosion the gas temperature leaving the heat transfer surface in boiler is kept around 150 degrees centigrade, ranging from 120 to 155.
