摘要

通过分析发电厂循环水稳定性的各种判断方法

确定将安定指数法用于循环水水质稳定性的在线监测。采用电位滴定法对水样碱度进行测定

通过试验室试验

找出了电位滴定法测量碱度的主要影响因素并给出了最佳试验条件。试验结果表明

用安定指数法确定循环水稳定性

将电位滴定法用于测定水样的碱度

将其用于循环水稳定性的在线监测装置的研发是可行的。

Abstract

Through analysing various diagnostic methods for circulating water stability in power plants

it is determined to use the stability index method for on-line monitoring the circulating water quality stability.By using the potential titrimetric method

the alkalinity of water sample has been measured.Through tests in the laboratory

the main affecting factors in alkalinity measurement using potential titrimetric method have been found

and the optimal test condition being given.Results of tests show that the stability index method to be used for determining the stability of circulating water

and the potential titrimetric method to be used for measuring the alkalinity of water sample

as well as using them in developling an on-line monitoring system for circulating water stability all are feasible.
