<P>PROBLEM TO BE SOLVED: To provide a gas turbine intake filter device capable of lengthening the replacing service life of a filter, while maintaining the dust collecting ratio of a degree of not causing large output reduction in the gas turbine. <P>SOLUTION: This gas turbine intake filter device 1 is arranged in an intake system of a gas turbine facility, a plurality of stages are arranged in the air current direction of the intake system, and the respective stages have filters 2 and 3 formed of one or a plurality of filtering material layers. Among the whole filtering material layers for forming a plurality of stages of filters 2 and 3, the most downstream side filtering material layer 32 has the particle collecting ratio higher than the upstream side filtering material layer 31, and the particle collection ratio of the most downstream side filtering material layer 32 is 95-99% to a particle having the particle size of 0.3 μm. <P>COPYRIGHT: (C)2013,JPO&INPIT |
