Plant Combats Corrosion in Idled Boilers | Chemical Processing

Aug 12, 2016 · The Terry Bundy N 2 generator supplies 5-psig nitrogen to the low-pressure and high-pressure drums during wet layups; the nitrogen also serves to "push" water from an HRSG during dry layup draining. A nitrogen pressure of 5 psig is maintained during the dry layup, provided no major tube work is required. An obvious major concern with nitrogen blanketing — and why some plants don't use

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
