PROBLEM TO BE SOLVED: To provide an acoustic liner for a gas turbine combustor capable of consuming an appropriate amount of purge air, increasing an amount of combustion air burning in the gas turbine combustor, decreasing combustion gas temperature, and reducing a generated (discharged) amount of NO.SOLUTION: A acoustic liner 50 for a gas turbine combustor includes: a number of holes 11a drilled circumferentially in a wall of a combustion chamber 2, inside which a combustion zone is formed; and a housing 11b that is disposed so as to surround an outer circumferential side of the combustor chamber 2 in the region where the holes 11a are drilled, and has a resonance space formed between the housing 11b and the wall of the combustion chamber 2. Evenly spaced multiple purge holes 51 are drilled circumferentially in and over both one side and the other side of the housing 11b. |
