Flue Gas - an overview ScienceDirect Topics

Various heat recovery schemes are used to recover this energy. In some units, the flue gas is sent to a CO boiler where both the sensible and combustible heat is used to generate high-pressure steam. In other units, the flue gas is exchanged with boiler feed water to produce steam via the use of a shell/tube or box-type heat exchanger.

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.
