PROBLEM TO BE SOLVED: To provide a gas turbine combustor that suppresses generation of combustion oscillation to improve reliability.SOLUTION: A gas turbine combustor includes a combustion chamber into which fuel and air are supplied, an air hole plate located on an upstream side wall surface of the combustion chamber with a plurality of air holes formed in concentric circular rows, and fuel nozzles disposed at an upstream side of each air hole of the air hole plate. In at least one row of the air holes formed in the concentric circular rows on the air hole plate, distances between leading ends of the fuel nozzles and a combustion chamber side surface of the air hole plate are different in a circumferential direction. |
