燃气轮机进气过滤系统是保护压气机叶片和燃气透平的重要设备,但其设计和运行过程中的重要性常常被忽略。分析了空气污染物对燃气轮机的危害以及进气过滤系统对燃气轮机运行安全的影响,介绍了进气过滤器和滤材特性对进气过滤系统性能的决定性作用。同时，根据国内燃气电厂实际运行情况,指出目前进气过滤系统运行存在的主要问题和原因,计算了进气过滤系统压降对燃气轮机性能的影响大小,分析了进气过滤器抗湿性能和消静电的实验结果。根据实验结果，建议采取加强采购抽检,根据标准EN 779—2012 Particulate Air Filters for General VentilationDetermination of the Filtration Performance严格执行消静电、抗湿性标准试验的应对策略,确保进气过滤系统具有良好的性能,保证燃气轮机安全高效运行。
Air intake filtration system is an important equipment to protect compressor blades and gas turbine, but its significance in the design and operation stage is often overlooked. This paper presents the analysis on the harmful effect of air pollutants on gas turbine and the influence of air intake filtration system on the safe operation of the gas turbine and the reasoning behind the influence; and explains how the characteristics of the air intake filter and filter materials determine the performance of the filtration system. The main problems and causes of the current operation of the intake filtration system are identified based on the actual operating experience of domestic gas-fired power plants. The influence of the pressure drop in the air intake filtration system on the actual performance of the gas turbine is calculated. Finally, the experimental results of moisture tolerance and static elimination on the air intake filter are analyzed. As a rectification measure, it is proposed to impose enhanced sampling tests during procurement of the filtration system, and strictly implement standard tests on antistatic and moisture tolerance performance according to the standard EN 779 - 2012, to guarantee the expected performance of air intake filtration system and the safe and highly efficient operation of the gas turbine.
