The invention provides a gas turbine intake air filter unit, wherein flow resistance of intake air passing through a tertiary filter layer does not become unreasonably great despite the filter layers are increased from two stages to three stages, and a balance of collecting efficiency of the filter layers and the intake air flow resistance is optimized.A weather louver 10 , a primary filter layer 11 , a secondary filter layer 12 , and a tertiary filter layer 13 are sequentially disposed from an upstream side in the filter unit 1 installed at an upstream ...
1. A gas turbine intake air filter unit, comprising:a primary filter layer, a secondary filter layer, and a tertiary filter layer placed at an upstream side end portion of an intake duct that leads intake air into an internal area of a gas turbine and sequentially aligned from an upstream side; whereinsaid primary, secondary and tertiary filter layers respectively include a plurality of unitary filters; andsaid plurality of unitary filters of said tertiary filter layer are aligned in such a manner that at least a recess is provided in a downstream direct...
