摘要
环境条件的变化会对燃气轮机及燃气-蒸汽联合循环发电机组运行产生影响。以GE 6FA.03燃气轮机为例,定量计算了环境温度及大气压力的变化对机组满负荷功率及热效率的影响。环境温度升高会导致燃气轮机热效率、燃气-蒸汽联合循环热效率、燃气-蒸汽联合循环机组功率的降低,且环境温度对燃气-蒸汽联合循环机组功率的影响最为明显;大气压力升高会一定程度上提高燃气轮机和联合循环的热效率和功率,但是其造成的影响远低于环境温度变化的影响。
The variations of environmental conditions can affect the operation of gas turbine and gas and steam combined cycle unit. The effect of variations of ambient temperature and atmospheric pressure on full load power and thermal efficiency of the units are calculated quantitatively by taking GE 6FA. 03 gas turbine for example. The rising ambient temperature can reduce thermal efficiencies of gas turbine and gas and steam combined cycle and the power of gas and steam combined cycle unit. The ambient temperature has greater effect on power of gas and steam combined cycle unit. The increasing of atmospheric pressure can increase the thermal efficiency and power gas turbine and gas and steam combined cycle to some extent, but its effect is far less than effect of variation of ambient temperature.
