Study on Monitoring Water Quality Stability of Cycle Cooling Water by Stability Index in Power Plant

In this paper, stability index method was used to determine the stability of power plant cycle cooling water. It solved the problem that exists in in most power plants. By comparing with other water quality stability methods, the result of static and dynamic experiments determined the feasibility of stability index method in monitoring the stability of power plant cooling water. This method avoids the using restrictions of other methods. So it has a more objective, reliable and real-time feature, which can predict the fouling or corrosion tendency of cycle water system quickly. Moreover, it is conducive to the stability, safety and economic running of equipment.
