<P>PROBLEM TO BE SOLVED: To provide a structure that strikes a balance between a low NOx and a combustion stability, in a gas turbine combustor. <P>SOLUTION: The combustor 2 includes: a combustion chamber 50 from which fuel and air are supplied; an air hole plate 33, which is located in an upstream side of the combustion chamber 50, and which has a plurality of air holes 32; and a fuel nozzle 31 for supplying fuel to the air holes 32 of the air hole plate 33. The air hole plate has an inner peripheral side plane and an outer peripheral side plane, which are the planes vertical to a central axis direction of the air hole plate in a combustion chamber side, respectively. The inner peripheral side plane is located in a downstream side more than the outer peripheral side plane, and the inner peripheral side plane is connected with the outer peripheral side plane by the plane or a smooth surface. <P>COPYRIGHT: (C)2012,JPO&INPIT |
