摘　　要：本文以燃气轮机作为发电装置,分别采用简单循环与回热循环,提出天然气冷热电联产系统两套方案。利用数值分析方法,对比分析各方案的系统效率与经济性指标。分析表明:基于回热循环的燃气轮机联产系统在经济效益和能源利用效率方面,相比简单循环联产系统都有十分明显的优势。Two natural gas-fired CCHP systems are designed,separately based on Brayton cycle and recuperative cycle,both of which utilize gas turbine to generate electricity.Comparative analyses of the efficiency and economic index for the two systems are conducted by use of the numerical stimulation method.The results show that the recuperative cycle system has distinct advantages both in economic benefit and energy utilization,compared to the Brayton cycle system.
