摘要

本文将氯离子在线监测数据作为一项关键控制指标

结合精处理出水的其他水质监测数据

对精处理系统进行优化

得到精处理混床铵型运行或部分铵型运行的可能性。优化后

某电厂超超临界机组精处理混床制水量至少提高2倍

运行周期至少为氢型运行时的3.3倍

在保证机组安全运行的同时经济效益和节能减排效果显著。该结论可为其他超(超)临界机组、核电站、具有凝结水精除盐装置的亚临界汽包炉等精处理系统提供一种优化运行方法。

Abstract

The on-line monitoring data of chlorine ion was taken as a key control parameter for power plant condensate polishing system

and the optimized operation test was carried out in combination with other water quality monitoring data to determine the possibility of mixed bed ammonium operation or partial ammonium operation. After the optimization

the water yield of the ultra-supercritical unit mixed bed in a certain power plant was increased by at least two times

and the operating cycle was at least 3.3 times of that of the hydrogen operation

which produced significant economic benefits

energy saving and emission reduction under the condition of ensuring the safe operation of the unit. This conclusion can provide a method for optimizing the operation of other(ultra) supercritical units

nuclear power plants

and subcritical units with condensate polishing devices.
