【摘要】:为了筛选出适宜于闪蒸-双工质联合发电系统的循环工质,建立了闪蒸-双工质联合发电系统的热力学模型。在这个计算模型中,采用热水温度范围为100~150℃,热水流量取为36t/h,冷却水进口温度设定为15℃。以单位热水净发电量、热效率、?效率和系统不可逆损失作为联合系统性能的评价指标,研究5种有机工质(R236fa、R600a、R600、R245fa、R601a)的运行参数,比较不同地热流体温度条件下这5种有机工质的做功能力,确立了联合发电系统的最佳循环工质。研究结果表明:联合系统的净发电量随着闪蒸温度的增加呈先增大后减小的趋势,每种工质都有一个最佳的闪蒸温度使得联合系统的单位热水净发电量达到最大;综合考虑这5种工质的环保性能和热力学性能,工质R245fa是综合性能最好的工质,可作为闪蒸-双工质联合发电系统的有机工质。
