我国目前运行的20万千瓦汽轮机,是仿照原苏联40年代的技术、50年代的图纸设计生产的,设计年代早,技术落后,经济性、可靠性欠佳,其低压缸缸效率比世界先进水平约低8 % - 10% ,每台每年多耗标准煤1600吨,目前我国有120多台这种类型的汽轮机,每年要浪费大量的能源.为了提高汽轮机的效率,节约全球能源,联合国开发计划署投资援助190万美元,在全世界招标,对我国20万千瓦汽轮机低压缸进行改造,东方汽 The 200MW steam turbine currently running in our country is modeled on the technology of the 40s of the former Soviet Union and designed and produced in the drawings of the 1950s. The designed age is earlier, the technology is backward, the economy is less reliable, and the efficiency of the low-pressure cylinder is higher than that of the world advanced level About 8% -10% lower, each consuming more than 1,600 tons of standard coal annually, at present, there are over 120 steam turbines of this type in our country, which consume a lot of energy every year.In order to improve the efficiency of steam turbines and save the global energy, the United Nations Development Program Department of investment assistance 190 million, bidding in the world, China’s 200,000-kilowatt turbine low-pressure cylinder to transform the Dongfang Steam
