PROBLEM TO BE SOLVED: To provide a combustor capable of forming a flame into an arbitrary shape, thereby making it possible to decrease a metal temperature of a liner while maintaining, for example, flame stability.SOLUTION: A gas turbine combustor comprises burner that includes: an air hole plate in which a plurality of air holes for injecting fuel and air is formed; and a liner forming a combustion chamber in which the injected fuel and air are combusted, an air hole string being formed by arranging a plurality of air holes on a circumference, and the burner being configured by one or more air hole strings. An air hole is provided whose at least either a circumferential inclination angle that is an angle formed between a burner central axis projected line that includes an air hole central axis of each air hole and that is projected onto a plane in parallel to the burner central axis and the air hole central axis, or an inward angle that is an angle formed between a projected line on an air hole outlet plane of the air hole central axis and a tangent of a circle centering around the burner central axis and passing through a center of an air hole outlet differs from that of the other air holes arranged on the same circumference. |
