据《Gas Turbine World》2013年9-10月刊报道,针对7HA.02燃气轮机的订单是GE的H级燃机从蒸汽发展转变到空气冷却机组的一个里程碑,空气冷却的燃机将以超过61%的联合循环效率运行。在今年9月末,GE宣布了来自美国电力公用事业公司Exelon对于4台它新生产的60 Hz 7HA.02燃气轮机的订单。所有4台燃气轮机将在2016年和用于在没有补燃情况下每台额定输出功率为1 000 MW的2个2×1联合循环动力装置的汽轮机和发电机一起发运。
According to the report from Gas Turbine World in the September-October 2013 issue, orders for 7HA.02 gas turbines are a milestone in the transition of GE’s H-class gas turbines from steam to air cooling units, with air-cooled turbines exceeding 61%. The combined cycle efficiency runs. At the end of September this year, GE announced the purchase of four new 60 Hz 7HA.02 gas turbines from Exelon, the US utility. All four gas turbines will be shipped together with turbines and generators for two 2×1 combined cycle power plants with a rated output of 1 000 MW each in the absence of supplemental combustion in 2016.
