Water quality management method and water quality management system of the boiler water

摘要

PROBLEM TO BE SOLVED: To continuously observe a water quality component of boiler water.;SOLUTION: In a water quality management method of circulated boiler water, a supply amount and a discharge amount of the boiler water are measured, an injection amount of an electrolyte to the boiler water is measured, a concentration of the electrolyte dissolved in the boiler water after the lapse of a detection time is calculated on the basis of an initial amount of the boiler water, initial concentration of the electrolyte, a supply amount and a discharge amount of the boiler water at a prescribed detection time, and an injection amount of the electrolyte at the detection time, and the change of water quality of the boiler water is detected by comparing an estimated value of electric conductivity of the boiler water with a measured value of electric conductivity of the boiler water on the basis of the concentration of the electrolyte.;COPYRIGHT: (C)2014,JPO&INPIT
