摘　　要：国电龙山发电厂1号机组为河北省南网投运的首台大型直接空冷机组,重点介绍该机组空冷凝汽器(空凝器)冬季热态清洗过程。经过多次对空凝器热态清洗方案的优化,合理设计临时清洗系统,使整个冬季热态清洗过程仅用了4 d时间。清洗期间,空凝器未发生冻结现象,使1号机组顺利地提前投产运行。The unit No. 1 in Guodian Longshan Power Plant is the first large- capacity air- cooled unit having been put into operation in the southern power grid of Hebei Province,the process of hot- state cleaning of air- cooled condenser for said unit in winter season has been emphatically presented. Through optimization of hot - state cleaning scheme for the air - cooled unit in many times and reasonable design of the temporary cleaning system,the entire process of hot - state cleaning in winter season is completed only in four days, freezing phenomenon has not occurred on the air- cooled condenser,making the unit no. 1 being successfully put into operation in advance.
