摘　　要：为了对未来混氢燃气轮机的运行提供相关的基础数据与理论指导,研究了向甲烷中添加H_(2)对9F级燃气-蒸汽联合循环机组效率的影响。基于Aspen Plus软件建立了联合循环模型,其中燃气轮机模型以PG9351FA型燃气轮机为基础,蒸汽轮机模型中的余热锅炉采用三压再热结构。并对燃气轮机、蒸汽轮机和联合循环的输出功率以及效率等进行了分析。结果表明:随着燃料中H_(2)质量分数由0增加到100%,燃气轮机输出功率增加了5.02%,效率增加了1.3%;蒸汽轮机输出功率增加了0.59%,但是蒸汽轮机效率却减小了2.9%;同时,联合循环输出功率增加了3.43%,效率增加了1.2%,因此向甲烷中掺混H_(2)可以提高燃气-蒸汽联合循环机组的经济性。In order to provide relevant basic data and theoretical guidance for the operation of hybrid hydrogen gas turbines in the future,this paper studied the effect of methane mixed with hydrogen on the efficiency of 9F class gas-steam combined cycle unit.The combined cycle model was established based on Aspen Plus software.The gas turbine model was based on the PG9351FA gas turbine,and the waste heat boiler in the steam turbine model adopted a three-pressure reheat structure.The output power and efficiency of gas turbine,steam turbine and combined cycle were analyzed.The results show that with the increase of mass fraction of H_(2) in the fuel from 0 to 100%,the output power of the gas turbine increases by 5.02%,and the efficiency increases by 1.3%.The output power of the steam turbine increases by 0.59%,but the steam turbine efficiency decreases by 2.9%.Meanwhile,the combined cycle output power increases by 3.43%,and the efficiency increases by 1.2%.Therefore,adding hydrogen into methane can improve the economy of gas-steam combined cycle unit.
