Boiler water treatment - Lenntech
The treatment and conditioning of boiler feed water must satisfy three main objectives:. Continuous heat exchange; Corrosion protection; Production of high quality steam; External treatment is the reduction or removal of impurities from water outside the boiler. In general, external treatment is used when the amount of one or more of the feed water impurities is too high to be tolerated by the

Sulfites for Oxygen Control Yamatho Supply
Since oxygen is not an ionizable gas, its solubility is much more temperature dependent than is carbon dioxide. Low temperature make up water contains as much as 10 mg/L of oxygen and hot feedwater about 3 mg/L. A variation from 40° F to 80° F in our water source results in a drop in oxygen content from 13 ppm to 8 ppm.
