摘要： This burner comprises a burner outer cylinder, a cylindrical burner inner cylinder provided inside the burner outer cylinder, a compressed air flow channel demarcated between the burner outer cylinder and the burner inner cylinder, and a plurality of fuel nozzles provided inside the burner inner cylinder, the compressed air flowing through the compressed air flow channel being substantially reversed in flow direction in the end of the burner inner cylinder and led into the plurality of fuel nozzles. The compressed air flow channel is provided with a fuel injection peg comprising an upstream fuel injection peg for injecting up-stream fuel and a downstream fuel injection peg for injecting downstream fuel, and is configured so that upstream fuel concentration fluctuations caused by pressure fluctuations in the burner reduce the peak of downstream fuel concentration fluctuations in the burning initiation position of the burner.

摘要： The present invention provides a combustor tail pipe capable of enduring conditions with a more severe thermal environment. This combustor tail pipe (20) has a tube-shaped barrel body (21), a tube-shaped outlet barrel (32) which is joined to the downstream end of the barrel body and which forms a barrel (B) in cooperation with the barrel body, and an inner flange (36) which extends from the downstream end of the outlet barrel toward the outer peripheral side of the outlet barrel. The outlet barrel (32) and the inner flange (36) are formed as an integrated member. The outlet barrel (32) has formed therein a groove (35) provided on the upstream side of the inner flange at a position along the inner flange, and the groove (35) is recessed from the outer peripheral side to the inner peripheral side and extends in the circumferential direction. The outlet barrel (32) has also formed therein a cooling fluid path (33) extending along the axis (Ac) of the barrel (B) and open to the groove.
