摘　　要：针对某电厂超低排放改造后中间热媒烟气换热器系统在回收热量时易造成凝结水水质恶化问题,提出新的冲洗方案和排放管路改造方案,减少了系统冲洗时间及水量消耗,消除了系统冲洗盲区,也可以消除原系统排放时的安全隐患。To solve the problem that the quality of condensed water got deteriorated when the energy recovery system of media gas-gas heater （MGGH） was put into use after ultra-low emission transformation of the coal-fired power plant, a new retrofit scheme was proposed and implemented concerning flushing and arrangement of the pipeline, which has helped to shorten the processing time, reduce the water consumption, eliminate the blind area and remove the hidden danger in the system when it is flushed.

关 键 词：换热器 水质 冲洗
