Abstract

Abstract:

With the introduction of chimney-tower integration technology to China,the requirements for the quality of circulating water is getting stricter. Taking a coal-fired power plant adopted the chimney-tower integration tech- noique as example,the determination,design and running situaion of flue gas of this engineering is introduced. The effect of the composition and distribution situations of flue gas condensed liquid on the quality of circulating water is studied. The results show that cooling tower flue gas condensed liquid does not affect the pH of circulating water,but can increase the concentration of sulphate and suspended substance in circulating water. The results provide certain technical reference for the circulating water treatment of power plant systems.

Key words: chimney-tower integration, flue gas, condensation liquid, circulating cooling water

摘要：

随着烟塔合一技术在国内的引进,其对循环水水质的要求也更为严格.以某采用烟塔合一技术的燃煤电厂工程为例,介绍了该工程的烟气测定设计及运行情况,研究了烟气结露液体的组成及分布情况对循环水水质的影响.结果表明:冷却塔烟气结露液体不会影响循环水的pH,但会增加循环水中硫酸根和悬浮物的浓度,该结果为发电系统循环水处理方面提供一定技术参考.
