Summary:PROBLEM TO BE SOLVED: To provide a gas turbine combustor having a multi-cluster burner structure.SOLUTION: A gas turbine combustor comprises a swirler lip 13 provided on the peripheral part of an air hole plate 6, and a spring seal 12 provided in a portion where a combustor liner 9, and the air hole plate 6 and the swirler lip 13 are fitted to each other. The spring seal 12 has air holes for passage of a part of combustion air introduced in the gap between the outer periphery of the air hole plate 6 and the combustor liner 9. The swirler lip 13 has air holes for introducing a part of the combustion air passing through the air holes of the spring seal 12 into a combustion chamber. The combustor liner 9 has air holes at positions facing the air holes of the spring seal 12, which introduce a part of combustion air from the outside of the combustor liner 9 into the gap between the outer periphery of the air hole plate 6 and the combustor liner 9. A turn guide 19 for straightening the flow of the combustion air is provided at the end portion of the combustor liner 9 on the side where the combustor liner is fitted to the air hole plate 6.SELECTED DRAWING: Figure 5 【課題】マルチクラスタバーナー構造のガスタービン燃焼器を提供する。【解決手段】空気孔プレート6の外周部に設けたスワラリップ13と、燃焼器ライナ9と空気孔プレート6、スワラリップ13が嵌合する部分に設けられたスプリングシール12を備え、スプリングシール12は、空気孔プレート6の外周部と燃焼器ライナ9との間隙に導入した燃焼用空気の一部を通過させる空気孔を有し、スワラリップ13は、スプリングシール12の空気孔を通過した燃焼用空気の一部を燃焼室内に導入する空気孔を有し、燃焼器ライナ9は、スプリングシール12の空気孔に対向する位置に燃焼器ライナ9の外部から空気孔プレート6の外周部と燃焼器ライナ9との間隙に燃焼用空気の一部を導入する空気孔を有し、燃焼器ライナ9の空気孔プレート6と嵌合する側の端部に、燃焼用空気の流れを整流するターンガイド19が設けられていることを特徴とする。【選択図】図5
