Patent ID: 8579074

Claim:
An intake silencer for a gas turbine disposed in a sealed flow path of an intake of a gas turbine and configured by a sound-absorbing splitter group composed of a plurality of panel-shaped sound-absorbing splitters including a sound-absorbing material therein disposed in parallel along a gas flow direction, wherein a high frequency sound-absorbing splitter group composed of a plurality of sound-absorbing splitters that reduces high-frequency component noise of a frequency level centered on 2 kHz, each of said high frequency sound-absorbing splitters being 5 centimeters in width and a gap between a pair of adjacent high frequency sound-absorbing splitters being 5 centimeters, and a middle to low frequency sound-absorbing splitter group composed of a plurality of sound-absorbing splitters that reduces middle to low frequency component noise of equal to or below 1 kHz, each of said middle to low frequency sound-absorbing splitters being 20 centimeters in width and a gap between a pair of adjacent middle to low frequency sound-absorbing splitters being 30 centimeters, and said high frequency sound-absorbing splitter group and said middle to low frequency sound-absorbing splitter group are disposed separately in the gas flow direction.
