摘　　要：以常规热平衡法为基础,通过严格的数学推导,首次将等效热降理论应用于供热汽轮机抽汽供热循环做功与做功不足的计算,并得出了相应的计算模型。实例计算表明,本模型通用性好,计算准确简捷,为供热汽轮机热电联产总热耗量合理分配的研究奠定了基础。On the basis of the normal energy balance method, the authors first apply basic theory of equivalent heat drop to extraction heating cycle work and its shortage calculation for cogeneration steam turbine, by mathematical derivation strictly. According to the calculating results of some actual examples, It is＇ common good, accurate and simple, establish the foundation for studying the reasonable distribution of overall heat consumption on cogeneration steam.
