Gas Steam Boiler Failure Analysis

ETD Consulting-Boiler Tube Failure Analysis Project

ETD has recently carried out root cause failure analysis for a number of boiler tubes samples removed from oil & gas fired boiler units of two large power plants in Far East. Several of the superheater tubes had ruptured after 100,000 hours in service, causing forced outages. The tube mater

Finding the Root Cause of Boiler Tube Failures

Symptoms: Aggressive localized boiler tube 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

Boiler Safety Programs & Inspection Forms - SafetyInfo

Boiler accidents can occur when the boiler is allowed to operate without adequate water in the boiler. Proper functioning low water cutoffs are essential to prevent these types of accidents. Boiler damage can run from severe buckling and deforming of the boiler to complete meltdown or potential boiler explosions.
