摘　　要：提出了单级回热抽汽压力的穷举优化方法,分别对混合式与表面式加热器回热系统的抽汽压力优化问题展开数值优化算法研究。发现表面式加热器与混合式加热器的抽汽压力优化解存在非常明显的差异,因此,分别建立了两类加热器系统动力系数的计算模型,提出了基于附加冷源损失分析的结论。The arithmetic model of enumeration optimization for regeneration parameters is proposed, and the optimization results for heaters of contact type and surface type are calculated and analyzed. It is found that there exist obvious differences of optimal pressure between these two types of heaters. To explain this issue, the correctional models of the power coefficient were established for the two heaters respectively, and the results show that the additional heat loss caused by drain of the surface type heater in the condenser is an important cause of differences of optimal pressure and power coefficient between the two types of heaters.
