国产２０万千瓦汽轮机是６０年代的设计产品，自１９９２年首台２００ＭＷ机组投产以来，国内约有１５０台投入运行，在很多省份和地区承担着主力机组的任务。限于当时的设计和制造水平，机组的经济性比较差，汽轮机热耗一般在８５８２８７９２ｋ／ｋｗｈ之间，比世界先进水平 The domestic 200,000-kilowatt steam turbine is a design product of the 1960s. Since the first 200MW unit was put into operation in 1992, about 150 units have been put into operation in China, and they have assumed the task of the main unit in many provinces and regions. Due to the limited design and manufacturing level at that time, the economic efficiency of the turbines was relatively poor. The heat loss of steam turbines was generally between 85,828,792 k/kWh, which was higher than the world’s advanced level.
