| 摘 要： | 燃气轮机的性能与其所处的环境温度密切相关。当环境温度上升时 ,空气密度较小 ,由于燃气轮机是定容式动力机械 ,从而导致流过压气机和透平的质量流量减少 ,引起燃气轮机的出力下降。通常这种出力上的减小恰恰发生在电网最需要电力的时候。透平出力的降低可通过冷却压气机的进气而避免。燃气轮机的进气冷却是增加其出力的最有效的方法。本文的目的是介绍和讨论进气冷却的各种方法 ,影响其经济可行性的各种重要因素以及设计条件的选择原则。对蒸发冷却 (将进气冷却至接近湿泡温度 )和制冷冷却 (将进气冷却至湿泡温度以下 )这两类进气冷却方式进行了讨论 ,并介绍了几个成功地实施进气冷却的燃气轮机电站项目 |
| 关 键 词： | 燃气轮机 进气冷却 制冷装置 |

| Abstract: | A few gas turbine inlet air cooling systems are discussed.The performance of a gas turbine varies significantly with ambient air temperature.As the air temperature rises,its density decreases,resulting in reduced mass flow through the compressor and trubine,thereby causing a corresponding reduction in turbine output.Inlet air cooling is increasigly being recognized as one of the most cost effective means of increasing trubine capacity.The objective of the paper is to evaluate various methods of cooling the inlet air,the major factors that influence its economic feasibility,and the selection of design conditions. |
| Keywords: | gas trubine inlet air cooling chiller |
