Hydrogen embrittlement in boilers - Lenntech

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. Dissolved oxygen and carbon dioxide control in boiler feed water protects the boiler from corrosion. Membrane contractors can be used to replace
