摘要

火电厂灰水系统结垢问题时有发生。本文介绍了一种对灰水闭式循环系统，特别是浓灰浆输送系统的防垢新方法，即活性晶种与惰性晶种混合防垢法。研究结果表明，该防垢法可解决火电厂灰水闭路循环系统全程结垢的问题，且在运行中不需添加任河化学药剂，运行操作简便，适用范围广，无论冲灰水的结垢趋势有多大，均可得到满意的防垢效果，结垢速度可降低１０倍以上。

Abstract

Seale formation is a problem which frequently occures in the wet ash handling system in call fired power plants. Introduced in this peper is a new method of scale prevention by using active and inert crystals

which are suitable to the recycled ash sluicing system

especially to the dense ash handling system. The research and testing results show that this method is able to solve all-process scaling problem without adding any chemicals. It is easy for operation and has a wide application. No matter how high the scale tendency of ash slurry

the speed of scale formation can be reduced by at least 10 times.
