| 摘 要： | 汽轮机低压缸排汽压力修正曲线通常采用制造厂提供的曲线。在试验现场采用复杂的汽轮机变工况计算通常也无法实现。介绍了一种校核汽轮机低压缸排汽压力修正曲线的简化计算方法,来计算汽轮机性能修正曲线。这种方法可以对制造厂提供的修正曲线进行验证,也可以计算部分负荷及单阀运行状态下的汽轮机修正曲线。

| Abstract: | Normally the sophisticated turbine variable condition thermal performance calculation for LP turbine exhaust pressure correction curve verification is not possible for site test,and simplified thermodynamics is adopted for this purpose.This article introduced a simplified variable condition calculation method for turbine systems performance correction curves.This method can be used for verification of correction curves provided by the manufacture,or calculation of correction curves for the partial load conditions and turbine valve throttle conditions. |
