PROTECTING PERFORMANCE Eagle Filters Ltd Tel. +358 10 420 3070 Kalervonkatu 10 VAT No. FI10056470 Fax +358 10 420 3071 FIN-48600 Kotka [email protected]The correct selection of air filters is one of the most crucial factors affecting the operation and efficiency of a gas turbine. The difference between a successful and unsuccessful selection is measured in significant economical losses and severe impact to environment. What differentiates Eagle Filters from other filter manufacturers is that we do not provide bulk filters for applications requiring individual solutions. We will tailor the best solution in view of technology and economy for the current filter house of our customer. Air Inlet Filters for Gas Turbines m) Compressor fouling occurs when very small particulate pass through the filtration system and adhere to the compressor blades. The adhesion of dirt to the leading edges and surfaces of the finely balanced blades alters their aerodynamic properties and therefore the mechanics of the compressor. These changes are responsible for the reduction in effeciency and output of the turbine. There are no substantial differences between the best known filter brands when examining the ability to filter large particles, 1 μm and above. Capturing particulate of this size and above is comparatively simple, F8 filters have a >98% efficiency rate. This changes dramatically when considering the particulate that cause most fouling, 0.2 - 0.4 µm, with a peak at 0.3 µm. At this size F8 filters only achieve ~40% efficiency rate. In Industrial areas these smallest particles, such as unburned hydrocarbons, are very prevalent, primarily as a result of human activity: combustion processes, manufacturing, road traffic, air transport and shipping. The effects of fouling can be measured in financial and enviromental terms. The losses incurred by operators often runs into many millions of Euros much of which could be saved by employing better filtration.
