灰场回收水结垢趋势的判断及防垢措施

Judgment of Scaling Tendency of Recovered Water from Ash Yard And Prevention Measures

火力发电厂水力除灰系统是电厂的主要用水系统,为节约用水和保护环境,灰场水应回收利用。灰水回收系统结垢是影响灰水系统正常运行的关键,本文通过对A电厂灰水回收系统防垢措施的选择试验,阐述了影响防垢效果的多种因素及防治措施。

Hydraulic ash-handling system of a coal-fired power plant is an important water-consuming system. For the sake of water saving and environment protection, used water in the system must be recovered for reuse. Scaling of the recovering system is one of the key problems affecting the normal operation of the system. Through experiments to find measures preventing water recovering system from scaling, this paper addresses the factors impacting the scale-preventing result and their prevention measures.
