PROBLEM TO BE SOLVED: To effectively cut a can-shaped combustor so as to avoid pulsation.SOLUTION: A combustor transition part 24 is adapted so as to guide combustion gas in a high temperature gas flow channel 15 extending between a can-shaped combustor and a first step of a turbine 3 in a gas turbine 9. The combustor transition part 24 includes a duct having: an inlet port that is provided at an upstream end part and is adapted for connection to the can-shaped combustor 2; and a downstream end part adapted for connection to the first step of the turbine 3. The combustor transition part has side wall extension parts 20, 20a and 20b in which at least one of side walls 21a and 21b extends in a downstream direction so as to project from an outlet port 22. The side wall extension parts 20, 20a and 20b at least partially enclose a first resonator volume 28, and at least one of the side wall extension parts 20, 20a and 20b has a resonator hole 26 constituted as the neck of a Helmholtz damper. |
