| 摘 要： | 通过建立双工质循环发电系统的计算模型和理论分析系统热力过程,对双工质循环发电系统中蒸发器的最佳蒸发温度以及蒸发器和凝汽器的最佳端部温差进行了优化选择。计算结果表明,最佳蒸发温度除与热水初温和冷凝温度有关外,也与端部温差有关,并随之增加而减少。在热水初温130℃及冷凝温度48℃下,得到蒸发器及凝汽器的端部温差优化值均为6℃,对应的最佳蒸发温度为87℃。

| Abstract: | In a binary cycle hot water power generation systems,heat exchanger design is a very important task for a power plant construction.The optimum evaporation temperature and optimum pinch point temperature difference of the evaporator and condenser were decided,with establishing the simulation model and analyzing theoretically.The results indicated that the optimum evaporation temperature is related to the pinch point temperature difference and decreased along with the increase of the pinch point temperature,except for relating to the hot water initial temperature and condensation temperature.Under the constant value of the hot water initial temperature(130℃) and the condensation temperature(48℃),the optimum pinch point temperature values of the evaporator and the condenser are all 6℃,and the related optimum evaporation temperature value is 87℃. |
