Clean air is vital to all combustion processes. The prime function of an inlet filter system is to protect the gas turbine from pollutants in the air, as particles entering can cause costly damages like erosion, corrosion and fouling. Erosion is a permanent degradation, mainly caused by coarse particles,

while corrosion is caused by salt in combination with sulphur, and high temperatures. Smaller particles cause fouling of turbine blades, and thus affecting performance negatively. A secondary effect is an increase in temperatures, as heat transfer effectiveness is reduced, and ultimately the life of the hot section. Effective capture of particulate and airborne salt is therefore of vital importance for long and efficient operation. If not removed by the inlet system, particles will force operators to more frequently water wash the compressor, either by unnecessary on-line washing or during costly shut downs.

It is also important to understand the complexity of differentiating air filters. Most air filters remain in a system for months or even years. During this time, the filter will experience several environmental variations like changes in temperature, humidity, airflow velocity and particle load. To prevent this, and make sure our filters withstand the severe real life conditions once in operation

进气过滤系统的主要功能是保护燃气轮机免受空气中的污染,如颗粒进入会造成大的造价损害,如腐蚀或污垢。腐蚀是一种长久性的退化,主要是由大颗粒引起的,而腐蚀则是由盐与硫的结合和高温引起的。较小的颗粒会引起涡轮叶片的污垢,从而对涡轮的性能产生不利的影响。二次效应是温度升高,传热效率降低,会导致热寿命的延长。

因此,有效捕获微粒和空气中的盐对于长期有效运作至关重要。如果不被入口移除系统中,粒子会迫使操作者更频繁地用水冲洗压缩机,要么通过不必要的在线清洗,要么在昂贵的停机期间。所以匹配空气过滤器是很重要的。大多数空气过滤器在一个系统中停留数月甚至几年。在此期间,过滤器将经历几种环境变化,如温度、湿度、气流速度和颗粒负荷的变化。为了防止这一切,而且确保我们的过滤器一旦投入运行就能承受恶劣的现实条件;
