摘　　要：以常规热平衡法为基础,根据供热汽轮机凝汽循环和抽汽供热循环的实际耦合作用,推导出了考虑加热器散热损失的供热汽轮机热力系统等效热降与抽汽效率计算的矩阵方程,并将其应用于供热汽轮机新汽耦合做功的计算,其计算结果与常规热平衡法完全一致。本方法概念清楚,通用性好,为供热机组热力系统简捷快速地进行整体分析和局部定量计算奠定了基础。On the basis of the normal energy balance method, the authors developed the matrix model of cogeneration steam turbine thermal system used for equivalent heat drop and extraction efficiency calculation, including heater heating lose, apply it to main steam coupling work calculation and obtain same calculation result as normal energy balance method, according to the actual coupling action of condensing cycle and extraction heating cycle system. It is simple and clear, common good, establish the foundation for the integral and local parameters deciding quantity calculation-analyses fast made on cogeneration steam turbine thermal system.
