据《Gas Turbine World》2014年7~8月刊报道,1995年推出的GEMS9001H燃气轮机第一级动叶进口温度为1 426℃。四级涡轮的第1、2级为蒸汽冷却,包括第1、2级涡轮的静叶和动叶及第1级涡轮机匣。由于采用蒸汽冷却,H型燃机比空气冷却的G型燃机联合循环的功率增加60 MW(从420 MW增加到480 MW),效率提高2%(从58%增加到60%),NO_x排放减少一半。Alstom公司于1994年推出的新型高效的GT24和GT26型燃气轮机采用了SCS(顺序燃烧系统),2个环
According to Gas Turbine World’s July-August 2014 issue, the inlet temperature of the first stage of GEMS9001H gas turbine launched in 1995 was 1 426 ℃. The first and second stages of the four-stage turbine are steam cooled, including the stationary and moving stages of the first and second stage turbines and the first stage turbine casing. As a result of steam cooling, the H-combustor increased power by 60 MW (from 420 MW to 480 MW) and 2% more efficiency (58% to 60%) than the air-cooled G-combustor combined cycle with NO_x emissions Reduce by half. Alstom’s new highly efficient GT24 and GT26 gas turbines, introduced in 1994, feature an SCS (Sequential Combustion System), two rings
