What Is a Boiler Feed Water Treatment System and How Does .

Sep 26, 2016· After the softening process, some boiler feed water treatment systems will utilize dealkalization to reduce alkalinity/pH, an impurity in boiler feed water that can cause foaming, corrosion, and embrittlement. Sodium chloride dealkalization uses a strong anion exchange resin to replace bicarbonate, sulfate, and nitrate for chloride anions.

The Importance of Boiler Water and Steam Chemist

For most dissolved solids found in boiler water, it is negligible by comparison to mechanical carryover at pressures less than 2000 psig (13.8 MPa). An exception is silica for which vaporous carryover can be substantial at lower pressures. Vaporous carryover depends on pressure and on boiler water chemistry. It is not affected by boiler design.

Acceptable phosphate concentrations decrease from 140 mg/L in low pressure boilers to less than 40 mg/L at pressures above 1,500 pounds per square inch (10,000 kPa). Recommended alkalinity similarly decreases from 700 mg/L to 200 mg/L over the same pressure range. Foaming problems are more common with high alkalinity.
