Abstract:

Abstract:This paper briefly introduced the structure and composition of gas turbine inlet air filtration system, and analyzed the reason why inlet air fitration system cannot adapt to bad weather. Meanwhile, some optimized transformation plans are proposed in this paper, such as arranging the coarse filter G3 in the antifreeze warehouse and adding medium efficiency filter M5 etc. Furthermore, the net benefit in the first year after the optimized transformation is calculated. These optimized transformation plans could effectively decrease the rising velocity of air inlet system′s total pressure differences, reduce the workload and costs of maintenancing air inlet system, extent the lifespan of fine cartridge, enhance the adaptability against bad weather of unit, improve the security and stability of unit operation and increase the economic benefit of unit, which is worth of popularization and application in the optimized transformation of similar gas turbine inlet system.
