Finding the Root Cause of Boiler Tube Failures

Causes: Short-term overheat failures are most common during boiler start-up. Failures result when the tube metal temperature is extremely elevated from a lack of cooling steam or water flow. A typical example is when superheater tubes have not cleared of condensation during boiler start …
