摘　　要：对于高铜垢锅炉的化学清洗,直接采用EDTA清洗的在国内鲜见。本次通过实验论证及现场实施发现,采用优化后的除铜工艺结合EDTA清洗介质对锅炉高铜垢进行了清洗,清洗效果优良,值得推广使用。It is rarely seen of directly using EDTA chemical cleaning for high contents copper scales boilers in China. By experimental demonstration and field implementation,discovering that using optimised removing copper scales technology to clean high contents copper scales boilers combining EDTA chemical cleaning,the cleaning results is good,and it is worth to promote the use.
