单-双列调节级对汽轮机效率的影响分析

Efficiency Effect Analysis of Steam Turbine by Using Single-double Governing Stage

给出了汽轮机单-双列调节级的热力计算方法,绘出了单列和双列调节级的轮周效率曲线,通过比较分析得出单-双列调节级可以有效提高汽轮机各个工况下的有效效率,实例计算证明了本文模型、算法和结论的正确有效性。

The article explains the way to the thermodynamic calculation and gives the graph of the axle efficiency of the single-double governing stage. Compare and analysis show that the governing stage can availably enhance the efficiency of the turbine under the variable operation condition. The effectiveness and validity of the mode and arithmetic method and conclusion are proved by the example.
