摘要
以常规热平衡方法为基础,经过严格的数学推导,首次将等效热降理论应用于供热机组热力系统循环吸热量的计算,并提出了适用于不同类型供热机组热力系统的通用数学计算模型。经实例验证,该数学模型简捷、准确,将为不同类型供热机组热力系统热经济性的定量计算和热电联产总热耗量合理分配的研究奠定良好基础。
In this paper, the authors first apply basic theory of equivalent heat drop on the common circulation heat calculating model for all kind of thermal system in cogeneration steam turbine by mathematical derivation strictly, based on normal energy balance. According to the calculating results of some actual examples, the present method is simple and accurate, and foundation for the quantitative calculation and reasonable distribution of heat on all kind of thermal system in eogeneration steam turbine is established.
