<P>PROBLEM TO BE SOLVED: To provide a gas turbine combustor that prevents the generation of pressure fluctuation to improve the reliability of the combustor. <P>SOLUTION: The gas turbine combustor includes: a combustion chamber into which fuel and air are supplied; an air hole plate which are positioned on an upstream wall surface of the combustion chamber and on which a plurality of air holes are concentrically formed; and a plurality of fuel nozzles which are arranged upstream each air hole of the air hole plate. In the air hole plate, the center of a surface on the combustion chamber side is formed as a convex which projects most to the combustion chamber side, and an axial length of the air hole positioned at the most inner peripheral side of the air hole plate is shorter than those of the other air holes. <P>COPYRIGHT: (C)2012,JPO&INPIT |
