Finding the Root Cause of Boiler Tube Failur

Furnace water wall tubes can also fail from long-term overheat. In the case of water wall tubes, the tube temperature increases abnormally, most commonly from waterside problems such as deposits, scale, or restricted flow. In the case of either superheater or water wall tubes, eventual failure is by creep rupture.
