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

進氣過濾系統(tǒng)的主要功能是保護燃氣輪機免受空氣中的污染,如顆粒進入會造成大的造價損害,如腐蝕或污垢。腐蝕是一種長久性的退化,主要是由大顆粒引起的,而腐蝕則是由鹽與硫的結(jié)合和高溫引起的。較小的顆粒會引起渦輪葉片的污垢,從而對渦輪的性能產(chǎn)生不利的影響。二次效應(yīng)是溫度升高,傳熱效率降低,會導(dǎo)致熱壽命的延長。

因此,有效捕獲微粒和空氣中的鹽對于長期有效運作至關(guān)重要。如果不被入口移除系統(tǒng)中,粒子會迫使操作者更頻繁地用水沖洗壓縮機,要么通過不必要的在線清洗,要么在昂貴的停機期間。所以匹配空氣過濾器是很重要的。大多數(shù)空氣過濾器在一個系統(tǒng)中停留數(shù)月甚至幾年。在此期間,過濾器將經(jīng)歷幾種環(huán)境變化,如溫度、濕度、氣流速度和顆粒負荷的變化。為了防止這一切,而且確保我們的過濾器一旦投入運行就能承受惡劣的現(xiàn)實條件;

以上空氣過濾器技術(shù)參數(shù)金科過濾器通過第三方機構(gòu)認證公司進行測試并提供檢測報告。

These are general recommendations for gas turbine air inlet systems.
