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

Detecting and reducing boiler scale buildup in a

One of the most prominent issues experienced with boilers is the formation of calcium carbonate scale on boiler tubes due to improper calcium levels within the feedwater system supplying the boiler. If left untreated, this scale — even if only a couple millimeters thick — can cause uneven heating and increased operational costs and
