Gas Turbine Inlet-Air Chilling at a Cogeneration Facility 热电厂燃气轮机进气冷却
燃气轮机是定容发动机,其轴功率与燃烧空气质量流量成比例。如果降低压缩机进口处的空气温度以增加空气密度,发动机输出会提高。当燃烧式涡轮发电机用于发电厂时,增加的发动机输出会增加发电量。这就是在加利福尼亚州热电厂安装的空气冷却系统的案例研究中提出的概念。电厂还使用了带有进气冷却器的热能储存(TES)系统,以提高电厂的经济效益。该应用将炎热天气的发电能力提高了10%。关键词:燃气、涡轮机、进气口、空气、冷却、热电联产、大型、燃烧、储能、夏季、压缩制冷、制冰机、优化、经济性、性能、案例研究、美国。 引用:研讨会,ASHRAE Trans。1994年,第100卷,第一部分
Combustion gas turbines are constant-volume engines for which shaft horsepower is proportional to the combustion air mass flow. Engine output improves if the air temperature is depressed at the compressor inlet to increase the air density. When a combustion turbine generator is used in a power plant, increased engine output increases the electrical generating capacity. That is the concept presented in this case study of an air-chilling system installed in a cogeneration plant in California. The plant also uses a thermal energy storage (TES) system with the inlet air chiller the plant's economic performance. This application has improved the hot weather generating capacity by 10%.KEYWORDS: gas, turbines, inlets, air, cooling, combined heat and power, large, combustion, energy storage, summer, compression refrigeration, ice makers, optimisation, economics, performance, case studies, USA.
