摘要
对管式双级空气预热器上、下两级间采取不同连结方式引起传热温差场的差异，及对换热效果所产生的影响进行了分析，得出了从传热及热力学完善性考虑时。
Based on the consideration of temperature different field caused by linkage style of two-stage tubular air heater,the paper analyzes the results of Heat transfer from Heat transfer and Thermodynamics perfect,and points out that Z-type arrangement is more superior than C-type.
