Summary:To provide a gas turbine combustor that can suppress combustion vibration.SOLUTION: A gas turbine combustor 3 includes: a first burner 60 provided with multiple first nozzles 64 along an inner periphery of a cylindrical combustion cylinder 20; and a second nozzle 54 encircled by the multiple first nozzles 64. The second nozzle 54 includes a fuel injection hole 114 capable of injecting fuel. A distance between a centroid of the fuel injection hole 114 when being viewed from an axial direction of the combustion cylinder 20 and an outer peripheral edge of the fuel injection hole 114 varies depending on a position of the outer peripheral edge of the combustion cylinder 20 in the circumferential direction.SELECTED DRAWING: Figure 4 【課題】燃焼振動を抑制できるガスタービン用燃焼器を提供する。【解決手段】本開示の少なくとも一実施形態に係るガスタービン用燃焼器３は、複数の第１ノズル６４が円筒状の燃焼筒２０の内周に沿って設けられた第１バーナ６０と、複数の第１ノズル６４に取り囲まれた第２ノズル５４とを備える。第２ノズル５４は、燃料を噴射可能な燃料噴射孔１１４を有する。燃焼筒２０の軸方向から見たときの燃料噴射孔１１４の図心と燃料噴射孔１１４の外周縁との距離は、燃焼筒２０の周方向における外周縁の位置によって異なる。【選択図】図４
