Boiler problems: the 10 most common issues | startrescue.co.

Oct 10, 2018· Boilers can break down at any time, but usually fail in the winter months following a long period of inaction. The sudden pressure on the system’s components often cause a breakdown – at a time of year when a household needs heating and hot water most.

Finding the Root Cause of Boiler Tube Failur

Failures are catastrophic, thick-lipped failures that initiate from ID cracks that are oriented perpendicular to the direction of the stress. 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.
