摘要：

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。

关键词: 灰水闭路循环, 结垢, 复合配方阻垢剂

Abstract:

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.

Key words: ash-flushing water closed-circuit circulation, scale, compound scale inhibitor
