哈尔滨汽轮机厂先后设计制造了多种型号的超高压一次中间再热20万千瓦容量等级的汽轮机。其中~#34,~#55(制造厂编号,以下同)为三缸三排汽,末级动叶高度为665毫米,排汽环形面积3×4.178m~2=12.535m~2,以下简称该机型为3F665。第一台3F665于1972年在朝阳发电厂投运。~#69为三缸双排汽,末级动叶高度为710毫米,排汽面积2×4.617m~2=9.234m~2,简称为2F710。第一台2F710于1986年2月在巴基斯坦古杜电站投运。~#74为三缸双排汽优化机组,末级动叶
Harbin Steam Turbine Factory has designed and manufactured a variety of models of ultra-high pressure once the intermediate reheating capacity of 200,000 kilowatts of steam turbine. Of which ~ # 34, ~ # 55 (factory number, hereinafter the same) for the three-cylinder three-row steam, the final rotor blade height of 665 mm, exhaust annular area 3 × 4.178m ~ 2 = 12.535m ~ 2, hereinafter referred to The model is 3F665. The first 3F665 put into operation in Chaoyang Power Plant in 1972. ~ # 69 for the three-cylinder double-row steam, the final rotor blade height of 710 mm, exhaust area of 2 × 4.617m ~ 2 = 9.234m ~ 2, referred to as 2F710. The first 2F710 was put into operation at the ancient Guodu Power Station in Pakistan in February 1986. ~ # 74 for the three-cylinder double-row steam optimization unit, the last stage moving leaf
