초록

A high-performance filter for an intake air for a gas turbine according to the present invention includes a low-efficiency filter media and a high-efficiency filter media superposed closely on each other in the named order from an upstream side in a direction of an air flow. Each of the filter media is formed with a filtering area of 20 to 35 m2. The filter media having a filtration efficiency of 40 to 70% for particles having a particle size of 0.3 μm is disposed as a layer upstream in the air flow direction, and the filter media having a filtration eff...
