| Abstract: | The impossibility of unambiguously estimating phosphate concentration by measuring boiler-water conductivity in a high-pressure drum boiler (p b = 13.8 MPa) is shown. Mathematical models of ion equilibria in boiler water, which allow one to determine the concentration of phosphates and other ion admixtures from the measurement data obtained with the use of standard (conductormeters and pH-meters) in cooled samples of feedwater and boiler water, are described. |
