摘要/Abstract

摘要： 燃机空气进气系统在高湿环境下运行时阻力急剧增长（定义为“湿堵”）的问题严重影响了机组运行的安全性和经济性。在阐述燃气电厂湿堵案例基础上，分析了问题产生的机理，进而从提高过滤器耐湿性能和控制进气温湿度2个角度研究了被动预防和主动干预的应对策略。过滤器耐湿性能和压气机进气加热试验表明，提高过滤器耐湿性能和进气加热可以有效解决进气系统湿堵。

关键词: 燃机进气系统, 湿堵, 耐湿性能, 进气加热

Abstract: When gas turbines are operated under high humidity environments, the air intake filtration systems may experience rapid increase of resistance, which can seriously affect the security and economy of gas turbine operations, i.e. "wet-clogging". Based on the studies on the real case, the internal mechanisms of wet-clogging have been analyzed thoroughly in the paper. Furthermore, a passive preventive scheme by improving the water mist endurance and an active preventive scheme by adjusting the relative humidity and temperature of the inlet air were put forward respectively. According to the results from water mist endurance testing and compressor inlet bleeds heating (IBH), both approaches mentioned above are capable of resolving the issue of wet-clogging effectively.

Key words: air intake filtration systems, wet-clogging, water mist endurance, air intake heating
