分析贵溪冶炼厂冶炼烟气制酸转化工序的热管锅炉换热效率降低的原因，主要是热管中产生了不凝性气体及水垢。对二系列低温锅炉的下降管进行了疏通清理并煮炉，去除水垢；对一系列中温锅炉热管进行了在线管内工质更换检修。换热管经过处理后换热效率得到了明显提高，延长了热管的使用寿命，热管锅炉运行稳定。
分析貴溪冶煉廠冶煉煙氣製痠轉化工序的熱管鍋爐換熱效率降低的原因，主要是熱管中產生瞭不凝性氣體及水垢。對二繫列低溫鍋爐的下降管進行瞭疏通清理併煮爐，去除水垢；對一繫列中溫鍋爐熱管進行瞭在線管內工質更換檢脩。換熱管經過處理後換熱效率得到瞭明顯提高，延長瞭熱管的使用壽命，熱管鍋爐運行穩定。

The causes of efficiency decrease of the heat pipe boilers in the conversion section of Guixi Smelter's sulphuric acid plant based on off-gas were analyzed. The generation of non-condensable gas and scaling in the heat pipes were main causes. The downcomers of Series II low-temperature boiler were cleaned and boiled out to remove scale. The working fluid in heat pipes of Series I middle-temperature boiler was replaced by online repair. After treatment, boiler efficiency was improved significantly. The service life of the boilers was extended with stable running.
