摘要
Abstract
To study the effect of hydrogen blending in gas turbines on the performance of the heat recovery steam generator(HRSG),the outlet parameters of a 9F-class gas turbine under different hydrogen blending ratios are taken as the research subjects.The influence of changes in gas turbine exhaust temperature,flow rate,and moisture content on the HRSG output heat and thermal efficiency are analyzed.The results show that hydrogen blending leads to a decrease in exhaust temperature and flow rate,and an increase in moisture content.The reduction in exhaust temperature and flow rate results in a decrease in HRSG output power,while the increase in moisture content leads to an increase in HRSG output power.The decrease in temperature and the increase in moisture content both reduce the thermal efficiency of the HRSG,whereas the reduction in flow rate increases it.Considering all factors,hydrogen blending in gas turbines reduces the overall thermal efficiency of the HRSG.Under a reference condition of 15 ℃,the efficiency decreases by 0.93％(with 30％hydrogen blending)and 1.24％(with 100％hydrogen).关键词
