摘要
根据常规热平衡方法和等效热降的基本理论,推导出了用于凝汽式汽轮机热力系统热经济性分析和计算的同一性计算模型,实例计算结果与常规热平衡方法完全相同。它既能用于计算单位新蒸汽做功和循环吸热量,也能用于汽水流量分配的计算。它为凝汽式汽轮机热力系统进行局部定量计算和应用热力学第二定律进行定量分析奠定了基础,是一种对凝汽式汽轮机热力系统简捷快速进行整体分析的新的计算模型。
On the basis of the normal energy balance method and basic theory of equivalent heat drop, the authors developed the identical calculating model used for calculation and analysis of condensing steam turbine thermal system heat economics in this paper, and obtain the same calculation result as the normal energy balance method. It is used not only to calculate unit live steam work and circulation absorbing heat but also steam water flow distribution. Foundation for the quantitative calculation of local parameters and quantitative analyses by thermodynamic second law is established, and being a new calculating model with which we simply and quickly carry out the entirety analysis for condensing steam turbine thermal system.
