汽轮机效率,随汽温增加。从1900年以来,汽轮机汽温与效率,照每年的13°F增长率不断增加。 右图表示逐年增长情况,目下汽温已超过1000°F(590℃)照这曲线延伸的
Turbine efficiency increases with steam temperature. Since 1900, the steam temperature and efficiency of steam turbines have been increasing at an annual rate of 13°F. The graph on the right shows the year-on-year growth, and the steam temperature has exceeded 1000°F (590°C).
