(PDF) Failure Mode and Effect Analysis Power Plant Boiler
The failure mechanism of tube boiler is identified due to the short-term overheating as result of the localized flue gas flow following massive clinker formations in primary superheater region of the boiler. Operation of a new type of coal having low ash fusion temperature of 1210 which is close to the minimum specification limit of 1200 is identified as the main root cause of the failure of coal boiler …

Finding the Root Cause of Boiler Tube Failures
The flue gas temperatures at the boiler outlet are normally roughly 60K above the temperature of the product inside the steam boiler. At an operating pressure of 10 bar, which corresponds to a saturated steam temperature of 185°C, the flue gas temperature is therefore roughly 245°C. This corresponds to a flue gas loss of roughly 11%.
1/12/2020 · Analysis of the chemical composition and mechanical properties of the material and quantification of residual stresses by the hole drilling method were performed to assess possible causes of the failure of the steam boiler piping system.

In some steam drum designs, water level is extremely critical because the baffling may isolate a generating section of the boiler when the steam drum water level falls below a certain point. Thin-lipped bursts also occur in superheater tubes when steam flow is insufficient, when deposits restrict flow, or when tubes are blocked by water due to a rapid firing rate during boiler start-up.
