摘　　要：以常规热平衡法为基础,推导出了考虑加热器散热损失的供热机组T级抽汽供热循环系统热平衡矩阵方程,并将等效热降法应用于供热机组T级抽汽供热循环耦合汽水流量的分配计算,计算结果与常规热平衡法完全一致。本方法简单明晰,通用性好,为供热机组热力系统发电与供热的整体耦合分析计算奠定了基础,并可简捷快速地计算出热力系统连接方式以及局部参数变化对抽汽供热循环耦合汽水流量的影响。On the basis of the normal energy balance method, the authors developed the heating balance matrix model including heater heating lose of cogeneration steam turbine extraction heating cycle system, and apply the basic theory of equivalent heat drop to its coupling steam-water flow distribution calculation. It is simple and clear, common good. The deciding quantity calculation for extraction heating cycle coupling steam-water flow can be fast made specially because of the thermal system link mode and local parameters change, and foundation for the integral deciding quantity calculation and analyses on cogeneration steam turbine thermal system is established.
