Finding the Root Cause of Boiler Tube Failures

Causes: Tube damage occurs due to the combination of thermal fatigue and corrosion. Corrosion fatigue is influenced by boiler design, water chemistry, boiler water oxygen content, and boiler operation. A combination of these effects leads to the breakdown of the protective magnetite on the ID surface of the boiler tube.

Water-tube boiler - Wikipedia

Water-tube boiler. A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in
