Fluidized Bed Boiler - an overview | ScienceDirect Topics

The most common cause of corrosion in a CFB boiler is the chlorine-induced corrosion. This occurs mostly in the convective heat exchangers. It tends to appear together with high fouling rates due to the presence of alkali and chlorine in fuels that are high in calcium and potassium but low in silica.

Cause of Boiler Tube Failures - Chicago Tube & Iron

During periodic shutdowns of the boiler unit, tube failures can occur. Quite often they are related to dew point corrosion, an insidious condition that can penetrate up to 0.50" of steel per year. Thin walled tubes that normally last 10 years can become badly pitted during shutdown, and replacement tubing becomes an unanticipated expense.
