Steam Boiler Water Treatment

The purpose of the boiler water treatment is: 1 To neutralize acid forming salts in boiler water, i.e. maintain a slightly alkaline condition. 2 To provide scale removing and scale preventing chemicals. 3 To precipitate impurities into a sludge which can be removed by bottom and surface blows, and 4 To prevent corrosion by oxidation.
