Finding the Root Cause of Boiler Tube Failures

Symptoms: Aggressive localized corrosion and loss of tube wall.Pits can act as stress-concentration sites which can be initiation points for stress-related corrosion mechanisms. Causes: Oxygen pitting occurs with the presence of excessive oxygen in boiler water.It can occur during operation as a result of in-leakage of air at pumps, or failure in operation of preboiler water treatment equipment.

Boiler tube failures: Some case studies - ScienceDirect

Boiler tube failures are the main causes of forced outages of power generating units. Most of the common failure occurs in water wall tubes, superheater/reheater tubes, and economizer tubes. More than 80% of unscheduled boiler shutdown is due to boiler tube failure.

Failure Analysis of Boiler Tubes Used in a Thermal …

Failure of boiler water-wall tubes in a thermal power station is a very common phenomenon. 'High-temperature creep' is one of the main reasons behind these failures. A systematic study of the failures may lead to minimization of the failure occurrences preventing disruption of power generation and associated monetary losses.
