基于地表水质变化的火电厂循环冷却水监督参数的调整

Adjustment of Grcalating Cooling Water System Supervision Parapmeter Based on Surface Water Change

针对作为火力发电厂循环冷却水补充水源的地表水水质变化较大的问题,分析地表水水质变化对循环冷却水运行监督参数浓缩倍率、用水量等的影响,结合循环水系统水垢生成的机理及水质稳定控制原理,提出增加KSP指标来补充判断循环水系统水质稳定性及结垢倾监督控制方法。

Based on the large change of surface water quality used for the circulating cooling water system,analyzes the influence of water quality on concentrating ratio,water quanlity during circu- lating cooling water operation superviseion, proposes adding Ksv index as the supervision method for supervising water quality stability and solubility product trend, combined with mecha＇- nism of water product in circulating cooling water system and water quality stability control principle.
