本文对甘蔗糖厂中常用的三种典型热力循环(背压式热电循环,抽汽冷凝式热电循环和节流式热电循环)进行了(?)效率的分析,导出了热力循环优劣的简捷的统一判别式,它无需繁杂的计算,应用方便,对热力循环方案的选择和改进等方面均具有一定的指导意义。 This paper analyzes the efficiency of the three typical thermodynamic cycles (back pressure thermoelectric cycle, extraction condensation thermoelectric cycle and throttling thermoelectric cycle) commonly used in cane sugar plants, and derives a brief summary of the advantages and disadvantages of the thermodynamic cycle. The unified discriminant, which does not require complicated calculations, is easy to apply, and has certain guiding significance for the selection and improvement of the thermodynamic cycle scheme.
