Research on the anti-haze technology of gas turbine inlet system

介绍了燃气轮机进气过滤系统的构造及组成,分析了进气过滤系统无法适应恶劣天气的原因,提出了将粗效过滤器G3布置在防冻仓内、增加中效过滤器M5等优化改造方案,并计算了优化改造后第1年的净收益。该优化改造方案能够有效降低进气系统总压差上升速度,减少进气系统维护工作量及成本,延长精滤筒使用寿命,提高机组对恶劣天气的适应力,增强机组运行的安全性和稳定性,增加机组经济效益,值得在类似燃气轮机进气系统优化改造中推广与应用。

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.
