PROBLEM TO BE SOLVED: To provide a gas turbine combustor having improved fatigue strength by systematically reducing the rigidity of flanges installed on the upper and lower side of the tail cylinder outlet of the gas turbine combustor to reduce forcible deformation at a tail cylinder outlet side portion and reduce high stress to be generated at the side portion. SOLUTION: The rigidity of the flanges installed on the upper and lower walls of a tail cylinder rear end portion (outlet) of the gas turbine combustor is systematically reduced to reduce a rigidity difference between each of the upper and lower walls and a side wall of the tail cylinder rear end portion (outlet). This reduces forcible deformation resulting from thermal stress conventionally generated at the tail cylinder rear end portion (outlet) of the gas turbine combustor when operated, and reduces high stress which is easily generated at the side portion. As a result, the gas turbine combustor is provided with high fatigue strength. COPYRIGHT: (C)2007,JPO&INPIT |
