应用燃气轮机最突出的优点是能源的有效利用率高,总效率可达55～90%,因此,对一些工业部门,特别是炼油和化工企业有更大的吸引力。燃气轮机所产生的动力(电能)可用来驱动压缩机、泵、风机和电机;排出的气体温度较高(约600℃),还可以将其送入废热锅炉产生中压蒸气,用来驱动汽轮机发电机组以获得更多的电能。这种由燃气轮机发电机组与汽轮机发电机组组成的联合循环装置(见图1),
The most prominent advantages of using gas turbines are the high energy efficiency and the total efficiency of 55-90%, making them more attractive to some industries, especially to refineries and chemical companies. The power generated by the gas turbine (electric energy) can be used to drive compressors, pumps, fans and motors; the exhaust gases are hot (about 600 ° C) and can also be sent to waste heat boilers to generate medium-pressure steam to power turbines Unit to get more power. This combined cycle unit consisting of a gas turbine generator set and a turbine generator set (see Figure 1)
