摘　　要：针对化学回热燃气轮机循环发电效率较低和水耗偏大的问题,本研究提出了一种化学回注燃气轮机循环,即将燃气轮机的部分烟气回注至重整反应器,构建甲烷自热重整工艺,从而实现甲烷的高效转化。该技术实现了对燃气轮机烟气余热的提质,提升了循环出功。通过对燃料能量转化过程的改善及对系统换热过程的优化,在设计点工况下,新系统发电效率较化学回热系统提升了9.12%,且在低空压比和高燃气轮机入口温度的条件下体现出更良好的发电性能。经济性分析指出:系统经济回收期为2.3年,具有良好经济效益。Aiming at the problems of low power generation efficiency and water high consumption in the chemical recuperated gas turbine cycle,a chemical reinjection gas turbine cycle is proposed in this study.It is proposed that part of the flue gas in the gas turbine was put back into the reactor,the reaction of methane self-reforming reaction,and realize the efficient transformation of methane conversion rate.The technology features fully realize the effect of improving the quality of gas turbine flue gas waste heat,and improving the circulation work.Through the improvement of the fuel energy conversion process and the optimization of the heat transfer process of the system,the power generation efficiency of the new system is increased by 9.12%compared with that of the chemical heat recovery system at the design point,the performance of the power generation of lower pressure ratio and high gas turbine inlet temperature is better.The economic analysis shows that the economic payback period of the system is 2.3 years,which has good economic benefits.
