| 摘 要： | 工质所携带热能在热力系统的作功能力取决于在热力系统中的位置,与工质如何到达该位置无关。证明了两种等效热降法的重要关系,指出再热器吸热的作功效率有不同的选择方法。导出了在再热机组中,排挤单位非调节抽汽流经再热器流量份额的通用计算式,并进行了验证。

| Abstract: | Doing work capacity of work substance in thermodynamic system depends on position that work substance locates on, and is not relevant on how work substance reaches the position. Relation of two equivalent entropy drop method is conducted, and doing work efficiency of reheater has different choices. A universal formula is raised to calculate flow of reheater when a unit of work substance is pushed out from extraction steam in reheating unit, and verified by examples. |
