摘要： In a gas turbine combustor, a sectional shape in a radial direction of either one of an inner peripheral surface of a second inner tube member and an outer peripheral surface of a first inner tube member, in a fitting portion of a crossfire tube assembly, has a plurality of small-curvature portions having a curvature smaller than a reference curvature, the reference curvature being a curvature of a portion at a maximum distance from the center of the sectional shape. This configuration ensures the crossfire tube assembly is cooled, and the Possibility of thermal deformation or fire damage is lowered, without lowering the temperature of a combustion exhaust gas passing through the crossfire tube assembly of the gas turbine combustor.

摘要： The present invention provides a multi-can type gas turbine combustor including a plurality of combustors that mix and burn fuel and the air, the combustors being connected by a crossfire tube assembly. The gas turbine cools the crossfire tube assembly without lowering the temperature of a combustion exhaust gas passing through the crossfire tube assembly and prevents thermal deformation and fire damage of the crossfire tube assembly. In a gas turbine according to the present invention, a guide ring that guides a current of the air is provided in a position opposed to air holes. One side end portion of an annular space configured between the guide ring and a crossfire tube assembly is opened to a space on the inside of the crossfire tube assembly. The other end portion is a closed end connected to a partition wall configuring the crossfire tube assembly. The length of an annular space between the air holes and the closed end is set to three times or more as large as the diameter of the air holes. Further, a part of the air holes is drilled to tilt to the closed end of the annular space to cool the crossfire tube assembly including the guide ring with a small cooling air amount.

摘要： A gas turbine has a sealing structure at a connection portion between the transition pieces and a turbine inlet portion. A frame of the transition piece has an inner frame portion extending in the circumferential direction, an outer frame portion situated radially outside the inner frame portion, and a pair of side frame portions provided between both side end portions of the inner frame portion and the outer frame portion. The sealing structure includes an inner circumferential seal member and an outer circumferential seal member for sealing a gap between the inner frame portion and the outer frame portion and the turbine inlet portion, a side seal member for sealing a gap between the adjacent side frame portions, a first obstacle arranged in a gap between first corner portions adjacent to each other, and a second obstacle arranged in a gap between second corner portions adjacent to each other. The first obstacle and the second obstacle are in contact with the side seal member at the side of the turbine inlet portion.

摘要： A plurality of gas turbine combustors having a cross fire tube assembly that connects adjacent combustors. The combustors include combustion chambers having annular combustion air passages on outer peripheries thereof. The cross fire tube assembly has a dual pipe configuration including an inner tube that connects the combustion chambers of the adjacent combustors and an outer tube that covers therein the inner tube and connects the combustion air passages of the adjacent combustors. The cross fire tube assembly further has openings disposed between the inner tube and the outer tube of outer peripheral partition walls of the combustion air passages that are connected with the outer tube of the cross fire tube assembly centering on the inner tube. The openings allow combustion air to flow in areas upstream and downstream of the inner tube with respect to a flow of the combustion air flowing through the combustion air passages.

摘要： A gas turbine combustor has a burner with an inner casing and an outer casing, and an airflow path that supplies air between them. An opening introduces air from an outer circumferential side to an inner circumferential side of the inner casing of the combustor and an obstacle impedes the flow of the air upstream of the opening portion. The obstacle is formed by a perforated plate having an opening ratio representing a ratio of cross-sectional area of an opening portion of the holes formed in the obstacle to the sum of the cross-sectional area of the opening portion of the holes, and the cross-sectional area of the shielding portion that shields the flow of the air is low on an inner circumferential side of the obstacle and high on an outer circumferential side of the obstacle.
