Any chemical that is added to the water can increase the frequency of blow down, which affects operating costs of the boiler. In smaller low-pressure boilers (< 4500 lb/h and < 3.45 bars), chemical treatment alone may be used. A combination of steam deaeration and chemicals is most often used for larger high-pressure boilers.

Hydrogen embrittlement - Wikipedia

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.
