Finding the Root Cause of Boiler Tube Failures

Although the effects of thermally induced stress cycling can be seen in various types of boilers (e.g., firetube, cast-iron sectional and watertube), this article will be limited to an explanation of the failure mechanism and preventive measures in horizontal firetube boilers of the Scotch and firebox types.

Stress-Assisted Corrosion in Boiler Tubes (Technical

May 27, 2006 · A number of industrial boilers, including in the pulp and paper industry, needed to replace their lower furnace tubes or decommission many recovery boilers due to stress-assisted corrosion (SAC) on the waterside of boiler tubes. More than half of the power and recovery boilers that have been inspected reveal SAC damage, which portends significant energy and economic impacts.
