进气冷却式回热燃气轮机循环数值模拟和分析

针对简单循环燃气轮机性能偏低且易受大气温度变化的影响，本文提出了一种由吸收制机徊汽轮机组成的新型循环－－进气冷却式回热式燃气机循环，对其建模进行数值模拟和分析。结果表明，此循环既能较大幅度提高燃气轮机装置的性能，又能有效地改善燃气轮机性能对大气温度变化的敏感性。

Numerical Analyses of Gas Turbine Cycle with Suction Cooling and Regenerating

The efficiency and output power of simple cycle gas turbine are comparatively low and are easily influnced by the variation of environmental temperature. So a new type compound gas turbine cycle is put forward here to against the inherent short comings of simple cycle. The compound gas turbine is composed of gas turbine with absorption-type refrigerating machine and a suction cooler.The calculated results indicate that the compound cycle can have excellent performance and overcome the sensitivity of the performance to the variation of atmosphere temperature. It is a new concept and of practical value.
