摘要:燃气轮机作为天然气集中式发电、分布式发电以及基于天然气的多能互补系统的核心动力设备,其技术的掌握对于大型发电企业的安全生产和降本增效具有重要意义。目前,先进重型燃机技术已经发展到燃气初温高达1600℃的H/J级燃气轮机,联合循环效率超过 60%,轻型燃气轮机技术发展到单循环效率超过40%的第3代轻型燃气轮机。然而,由于我国燃气轮机技术长期以来相对落后,国内发电企业对于燃气轮机技术的掌握程度不高,导致现有天然气发电项目由于一些共性技术问题导致运行安全、生产效益受到影响。文中从发电企业对集中式和分布式天然气发电的需求出发,针对现有机组运行中出现的问题,提出了大型发电企业重型燃气轮机和轻型/微型燃气轮机的技术发展路径。

Abstract: Gas Turbine is the core device of centralized and distributed power generation and integrated energy system based on natural gas, thus the gas turbine technology is of significance for the safety and economic benefits of power plants. Currently, H/J class heavy - duty gas turbine has been developed, with the gas temperature reaching 1 500 ℃ ~1 600 C and combine - cycle efficiency beyond 60%. The simple - cycle efficiency of state of art aero derivative gas turbine has been up to 40%. Nevertheless, the gas turbine technology of China is relatively poor, which has caused a variety of problems in the operation of gas turbine power plants. In this paper, the current condition of the natural gas based power generation is analyzed and technology path of heavy duty, aero derivative and micro gas turbines is proposed for large power generation enterprises.
