Taylor Sulfite Test of Hot Boiler Water - YouTube
4/5/2016 · Sulfite is added to boilers to remove dissolved oxygen, which causes severe pitting corrosion. Theoretically, it takes about 8 ppm of sodium sulfite to react with 1 ppm of oxygen. To assure that this reaction goes to completion and that all oxygen is removed, an excess of 30 to 70 ppm of sulfite should be carried in the boiler water.
