<P>PROBLEM TO BE SOLVED: To provide an acoustic liner for a gas turbine combustor capable of making consumption of air for purge proper, increasing quantity of air for combustion which is subjected to combustion in the combustor of a gas turbine, lowering the temperature of a combustion gas and reducing production (discharge quantity) of NO<SB>x</SB>. <P>SOLUTION: The acoustic liner 30 for the gas turbine combustor is provided with many holes 11a bored along the circumferential direction on the wall surface of a combustion cylinder 2 in the inside of which a combustion zone is formed and a housing 11b arranged to surround the outer circumferential side of the combustion cylinder 2 in the zone where many holes are bored and having a resonance space formed between the wall surface of the combustion cylinder 2 and the housing 11b. A plurality of purge holes 31 are perforated on one side surface and/or the other side surface of the housing 11b along the circumferential direction over the whole circumference. <P>COPYRIGHT: (C)2012,JPO&INPIT |
