Abstract

　燃焼器の尾筒に配置される燃焼振動低減装置の外観性を向上できるガスタービンを提供することを課題とする。この課題を解決するため、燃焼振動低減装置３４は、燃焼器の尾筒３２に配置されてガス空間Ｓを形成すると共にガス空間Ｌと尾筒３２の内部とを複数の通気孔３４３を介して連通させる。また、燃焼振動低減装置３４は、プレス加工されて成る略Ｕ字型断面形状を有すると共に略Ｕ字型断面形状の開口部を尾筒３２側に向けつつ尾筒３２の外周に配置される第一部材３４１と、第一部材３４１の略Ｕ字型断面形状の開口部を塞いで第一部材３４１との間にガス空間Ｓを形成すると共に複数の通気孔３４３を有する第二部材３４２とを有する。そして、尾筒３２の径方向断面視にて、尾筒３２の外径が尾筒３２の軸方向に向かうに連れて変化するときに、尾筒３２の軸Ｌから第一部材３４１の略Ｕ字型断面形状の各屈曲部までの距離ｄ１、ｄ２が略一定に設定される。
