Against the rotating characteristics,low temperature corrosion ash deposition perform-ance and outlet gas temperature distribution rule of the rotary air preheater,it suggests non-bal-ance heat exchanger be added at the air preheater inlet and the flue duct be divided into several small ones.By properly reducing the inlet gas temperature of each small flue duct,the boiler ex-haust temperature becomes equilibrium and decreases on a whole.Finally,the boiler exhaust tem-perature can be reduced and the boiler efficiency and unit heat efficiency can be enhanced.%针对回转式空气预热器的旋转特性、低温腐蚀堵灰特征以及出口烟气温度分布规律，提出了在空气预热器入口设置非平衡换热器，将烟道分隔为几个小烟道，通过适度地降低各个小烟道的入口烟气温度，使锅炉排烟温度分布趋于平衡并整体有所降低，最终达到进一步降低锅炉排烟温度的目的，提高锅炉热效率或机组热效率。
