一、国产30万千瓦 汽轮机的概况 自从首台国产30万千瓦汽轮机在1974年10月投运已来,陆续已有六台机组投运。经过电厂、制造厂及其它有关部门的不断努力,机组日趋完善。在安全、经济、稳发等各方面水平都有显著提高。最好的机组年运行小时达7921小时;一次连续运行时间达 136天;煤耗335克/度;厂用电率2.86％(燃油)。这些机组的投运为满足国民经济对电力的需求作出了积极的贡献。 但是,我们也应看到国产机组在安全可靠性和负荷适应性方面还存在一些问题,经济性也比国内运行的同等容量的引进机组低。到目前为止,国产30万千瓦机组还未正
First, the overview of domestic 300,000-kilowatt steam turbine Since the first domestic 300,000-kilowatt turbine put into operation in October 1974 has come, after another six units have been put into operation. After the continuous efforts of power plants, manufacturing plants and other relevant departments, the unit is maturing. In terms of safety, economy, stability and other aspects, there has been a marked increase. The best unit in operation hours up to 7921 hours; a continuous operation of up to 136 days; coal consumption of 335 grams / degree; 2.86% plant electricity (fuel). The operation of these units made a positive contribution to meet the national economy’s demand for electricity. However, we should also see some problems existing in the safety and reliability of load-bearing units of domestic-made generating units and their economic efficiency is also lower than that of imported units of the same capacity operating in China. So far, the domestic 300,000-kilowatt unit is not yet positive
