本文通过超音速激波升压装置替代常规的加热器 ,建立了超音速激波升压回热系统。在此替代基础上 ,用等效热降理论分析了替代机组的热经济性变化情况 ,建立了替代机组热经济性变化的通用计算数学公式。实例计算结果表明通过超音速激波升压装置替代常规加热器 。

With the supersonic shock pressure lifting heaters replacing normal heaters,the regenerative cycle with supersonic shock pressure lifing heaters has been set up.Then,on the base of this replacement the variation of thermal unit's thermal economy is analysed with the equivalent enthalpy drop theory,and the general principles of the method are described in details to analyze the local thermal system changes.Finally,the caculating results of a example indict the thermal economy of power plant is increased mainly with the supersonic shock pressure lifting heaters replacing normal heaters.
