阻垢剂在火力发电厂灰水闭路循环中的应用

Application of scale inhibitor to ash-flushing water closed-circuit circulating of the heat power plant

介绍了在火力发电厂利用有严重结垢趋势的回水循环冲灰、冲渣系统中进行阻垢剂筛选试验、工业运行试验的情况。多年的应用结果表明 ,选用XH型高效灰水阻垢剂不仅解决了回水循环系统的结垢问题 ,而且充分利用了水资源 ,节约了设备的清洗和维护费用。

The article introduces the screening tests of scale inhibitors and industrial operation tests ,used in the heat power plant's ash and cinder flushing system with water closed circuit circulation,where there is a serious trend of scaling. Many year's application of scale inhibitor has shown that by using XH ash flushing water scale inbibitor of high efficiency,we can not only solve the problem of scaling in the water closed-circuit circulation system,but also make the best use of water recourse and save the costs for equipment cleaning and maintenance.
