Hydrogen Damage In Utility Boilers

Hydrogen Damage - an overview | ScienceDirect Topics

Khlefa A. Esaklul, in Trends in Oil and Gas Corrosion Research and Technologies, 2017 13.2 Types of hydrogen damage. The term hydrogen damage or HE encompasses wide range of the deleterious effects that have been associated with hydrogen on materials. These effects occur in both hydrogen sources, aqueous and gaseous environments, and vary from one material to another, the strength level

How to Alleviate Waterside Issues in Boilers and HRSGs

Hydrogen embrittlement is not normally observed in utility boilers, and there have been no reported evi- dence of failures attributed to embrittlement. Hydrogen damage is permanent damage caused by the reaction of hydrogen with the carbide phases present in carbon and low alloy carbon steels (pearlite colonies). Hydrogen damage does not

had to deal with hydrogen damage in a 1,250-psig utility boiler. Operations personnel insisted on running the unit for several weeks with a known con-denser leak. Even though the team did its best to maintain adequate boiler water chemistry, the ultimate outcome was extensive hydrogen damage that required a complete boiler retubing.

Hydrogen Damage in Power Boilers | J. Eng. Gas Turbines

Hydrogen damage has occurred in many different locations in boilers of a great variety of designs operating at pressures from 450 to 2700 psi. It has been found only in the steel underlying local areas of corrosion, where hydrogen would have been produced at a greater rate than elsewhere. Metal temperatures in the range from 600 to 950 F suffice.
