灰场回水系统阻垢剂用量的确定

Determination of the scale inhibitor concentration of backwater system from the store field of coal ash

导出了灰场回水系统结垢速度的理论计算公式 ,表明灰水质量比、水温、阻垢剂用量和回水流量等是影响结垢速度的主要因素。介绍了用模拟回水测定参数 ηCa和 f的方法 ,并结合电厂实际说明了如何用该公式确定阻垢剂用量。

The theoretical calculation formula of the scale velocity of backwater system from the store field of coal ash has been deduced in this paper. It shows that mass ratio of coal ash water,water temperature,scale inhibitor concentration,backwater flow and so on are the main factors which affect the scale velocity. The determination of the parameters η Ca and f by simulated backwater is introduced. It combines the power plant with practice,and explains how to use the formula to determine the scale inhibitor concentration.
