  • B. Sodium sulfite dosage. Once the oxygen content of the feedwater has been estimated, the sulfite dosages can be calculated. The sulfite dosage is the sum of the ppm needed to neutralize the dissolved oxygen, plus additional amounts needed to produce an acceptable boiler water residual.

  • Sulfites – typically for boilers up to 800 psi; sulfites react with oxygen to form sulfates that are removed from the boiler via blowdown. There are two forms of sulfite: Catalyzed – uses a catalyst to improve reaction time; Non-catalyzed – slower reaction time and must be used in hot water. Hydrazine – typically for boilers over 800
