Phosphate Ion Concentration In Boiler Water

Phosphate Ion Concentration In Boiler Water Related Information

Water and Steam chemistry-Deposits and Corrosion-

Phosphate hideout, hideout-return, and associated corrosion problems are now addressed by equilibrium phosphate treatment.13 The concentration of phosphate in the boiler water is kept low enough to avoid hideout and hideout return associated with load changes, thus it is always in equilibrium with the boiler.

In this method of suppressing corrosion and buildup of scale of the drum boiler to suppress corrosion and buildup of scale to the drum boiler by adjusting pH of the boiler water by adding a boiler agent mainly composed of a volatile substance, phosphate as a boiler agent is added so that concentration of phosphate ion in the boiler water is kept at a value less than 0.1 mg to one liter of the

Water Handbook -Boiler Deposits: Occurrence And

2  · When calcium phosphate is formed in boiler water of sufficient alkalinity (pH 11.0-12.0), a particle with a relatively nonadherent surface charge is produced. This does not prevent the development of deposit accumulations over time, but the deposits can be controlled reasonably well by blowdown.
