摘　　要： 阐述了复合相变换热器是一种新型的换热器,可以控制低温受热面金属不发生低温腐蚀,降低烟气的排放温度,该技术可用于各种燃煤、燃油、燃气锅炉、窑炉、注气炉、加热炉等换热设备,目前复合相变换热器应用于工业锅炉和循环流化床已有不少成功案例[1-3],而应用于大型电站锅炉还很少有报道,结合某330 MW电站锅炉尾部加装复合相变换热器的运行情况,对复合相变换热器应用于电站锅炉的运行情况及优缺点做了简要探讨。 The composite phase-changing heat exchanger is a new type of heat exchanger,which can prevent the boiler low temperature heating surface from corrosion,and reduce the temperature of flue gas.This technology can be used for a variety of heat transfer equipment,such as coal,oil,and gas boiler,kiln,gas injection furnace and heating furnace etc..A lot of phase-changing heat exchanger has achieved successful application in industrial boiler and circulating fluidized bed boiler,while there are few application in large power station boiler.Based on the actual operation of phase-changing heat exchanger applied in a 330 MW power plant boiler,the author discussed its advantages and disadvantages for reference.
