摘要
将燃气轮机的烟气余热作为热源,构建了有机朗肯循环(ORC)热力学和经济性优化模型,最后对燃气轮机-ORC耦合系统性能进行计算和讨论.结果表明:耦合系统的综合发电效率可达到38.0%,提高了7.0%,ORC有利于提高燃气轮机的整体性能.
Using the flue gas waste heat of gas turbine as heat source,this paper constructs the thermodynamic and economic optimization model of organic Rankine cycle(ORC)and finally calculates and discusses the performance of gas turbine-ORC coupling system.The results show that the integrated power generation efficiency of the coupled system can reach 38.0%,up by 7.0%.ORC system is conducive to improving the overall performance of gas turbines.
