used. Passivation can be accomplished in high pressure boilers, but high dosages of sulfite are needed. Sulfite is commonly supplied as sodium sulfite, Na 2SO 3; sodium bisulfite, NaHSO 3; ammonium sulfite, (NH 4) 2SO 3; or sodium metabisulfite, Na 2S 2O 5. Sodium sulfite can decompose to sulfur dioxide (SO 2)and hydrogen sulfide (H 2S) in the

Oxygen Control For High- and Low-Pressure Boiler Water …

Dec 09, 2015 · A boiler is called a high pressure boiler when it operates with a steam pressure above 80 bar. The high-pressure boilers are widely used for power generation in thermal power plants. In high-pressure boiler if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.
