驱动机组

The gasturbine own electricity generation efficiency does not calculate veryhigh, generally between 30%~ 35%, but produces the waste heat hazetemperature reaches as high as 450 ~ 550 ℃, may recycle the heatenergy transformation steam once more through the afterheat boiler,the actuation steam turbine sends time of electricity again, forms thegas turbine -- steam turbine union circulation electricity generation,the electricity generation efficiency may achieve 45%~50%, somelarge-scale units even may surpass 55%.

燃气轮机自身的发电效率不算很高，一般在30％～35％之间，但是产生的废热烟气温度高达450～550℃，可以通过余热锅炉再次回收热能转换蒸汽，驱动蒸汽轮机再发一次电，形成燃气轮机--蒸汽轮机联合循环发电，发电效率可以达到45%~50%，一些大型机组甚至可以超过55％。
