摘要： A combustor includes a combustion tube which has a tubular shape around an axis; a secondary fuel nozzle which is able to inject a secondary fuel in a radially inner direction with respect to the axis, inside the combustion tube; a fuel manifold which is disposed external to the combustion tube, and defines a fuel space which is able to temporarily store the secondary fuel; and a support which supports the fuel manifold with a gap extending radially from the combustion tube. The support has a support plate which is separated from the combustion tube by the gap and spreads in a circumferential direction with respect to the axis, and a support leg which is attached to the combustion tube and supports the support plate to define the gap between the support plate and the combustion tube.

摘要： An outlet seal connects a combustor that combusts a fuel to generate combustion gas and a shroud for a stator. The outlet seal has a gas path surface, a first connection section, and a second connection section. The shape of the gas path surface in a cross section perpendicular to an axis is an arc centered on the axis. The first connection section is formed at a first side in an axial direction and is connected to the combustor. The second connection section is formed at a second side in the axial direction and is connected to the shroud. The gas path surface has an inclined surface that is inclined with respect to the axis in a cross section including the axis, such that the flow-path area of a combustion-gas flow path is reduced toward the second side.

摘要： A fuel supply pipe assembly according to at least one embodiment of the present disclosure is a fuel supply pipe assembly for supplying fuel to a fuel nozzle provided on a side portion of a combustion liner of a gas turbine combustor, provided with: a fuel supply pipe for supplying the fuel to the fuel nozzle; a first flange portion capable of coupling with a flange portion of a fuel line for supplying the fuel to the fuel supply pipe; and a second flange portion capable of coupling with a top hat portion of the gas turbine combustor. The first flange portion has a plurality of radially outward protrusions arranged at intervals in the circumferential direction, and a plurality of first bolt holes penetrating the first flange portion in the axial direction. The first bolt holes are formed at the same circumferential positions as the protrusions, respectively.

摘要： There is provided an additive manufactured (AM) article formed of a Co based alloy having a composition comprising: in mass %, 0.08-0.25% C; 0.1% or less B; 10-30% Cr; 30% or less in total of Fe and Ni, the Fe being 5% or less; 5-12% in total of W and/or Mo; 0.5-2% in total of Ti, Zr, Nb and Ta; 0.5% or less Si; 0.5% or less Mn; 0.003-0.04% N; and the balance being Co and impurities. The AM article comprises crystal grains with an average size of 10-100 μm. In the crystal grains, segregation cells with an average size of 0.15-1.5 μm are formed, in which components constituting an MC type carbide phase comprising the Ti, Zr, Nb and/or Ta are segregated in boundary regions of the cells, and/or grains of the MC type carbide phase are precipitated at an average intergrain distance of 0.15-1.5 μm.

摘要： A cross-sectional area (Dout) of a transition piece outlet is set within a range of 0.79£DoutDin£0.9, relative to a cross-sectional area (Din) of a transition piece inlet of a combustor, and in a first stage turbine nozzle of a turbine connected to the transition piece outlet, a size (Hin) in a radial direction between upstream ends of the inner shroud and the outer shroud has a same dimension as a size (a) in a radial direction of the transition piece outlet. In a combustor transition piece that is included in the combustor having a center line (S) arranged with an angle to an axial center (R) of a rotor of a gas turbine and that guides combustion gas to the turbine, a cross-sectional area is monotonously reduced from the transition piece inlet in which the combustion gas flows to the transition piece outlet from which the combustion gas flows out.
