Finding the Root Cause of Boiler Tube Failures

Apr 18, 2009 · Ash erosion is one factor for pressure parts damage in high ash coal fired boilers and minimizing erosion will extend life of the pressure parts and thereby the availability of the boiler. As low grade coals are now emerging to be used in large quantity in boilers for power generation and process steam requirement it has become necessary to protect the pressure parts from ash erosion.

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
