摘　　要：贵溪冶炼厂首次在冶炼烟气制酸转化工序采用热管余热回收技术,运行2年后,热管锅炉换热效率降低。该厂对其原因进行了分析总结,认为是不凝性气体及水垢的产生导致换热效率降低,首次在国内同行业实施了热管在线修复技术,并取得了显著成效。Guixi smelter used heat pipe waste heat recovery technology in acid making with smelting gas conversion process for the first time. After 2 years operation, the heat exchange efficiency of waste heat pipe boiler was decreased. Guixi Smelter summarized and analyzed the reason; the heat exchange efficiency reduction was caused by the non -condensable gas and incrustant, implemented on - line maintenance technology firstly in domestic copper industry, acquired oblivious achievements.
