Boiler Carryover Cause, Effect and Prevention

In low/medium pressure boilers (<100 bar) entrained boiler water is the most common cause of steam contamination. Both mechanical factors such as boiler design, high water levels, load characteristics and chemical factors such as high solids concentration, excessive alkalinity, presence of contaminants contribute to the creation of carryover.

Water Handbook - Preboiler & Industrial Boiler Corrosion

Hydrogen embrittlement of mild steel boiler tubing occurs in high-pressure boilers when atomic hydrogen forms at the boiler tube surface as a result of corrosion. Hydrogen permeates the tube metal, where it can react with iron carbides to form methane gas, or with other hydrogen atoms to form hydrogen gas.
