A boiler water controlling system with basifier a mg/L Na3PO4+b mg/L NH3+c mg/L NaOH is investigate in the paper. Several calculate methods are discussed and the precision pH value calculating equation is proposed for a cycle chemistry system that has seven changing parameters coexisting together, i. e. a mg/L Na3PO4+b mg/L NH3+c mg/L NaOH+d mg/L H2SO4+e mg/L CH3COOH+f mg/L CO2+g mg/L SiO2. As an example of equilibrium phosphate treatment, the pH value are obtained and showed in graphics with the four kinds of impurity changing from 0 to 1.0 mg/L. The calculating results can be used in practical boiler water pH value control.
