摘要： In a combustion cylinder, gas turbine combustor, and gas turbine, an outer-side region of a cooling part which is a region on an outer side with regard to a reference line that is a straight line orthogonal to a radial direction and an axial direction of a gas turbine and passing through a center of a combustor basket, and an inner-side region of the cooling part which is a region on an inner side with regard to the reference line are set. A connection angle at an intersection between an extension line of an outer surface of the combustor basket along the axial direction and an inner surface of a combustor transition piece is set. First regions set at positions near the reference line in either the outer-side region or the inner-side region, and second regions with a larger connection angle than the first regions, set at positions farther from the reference line than the first regions are set. The second regions are set to have a higher flow rate of a cooling medium than the first regions.

摘要： A seal member (7) is provided between a combustor disposed around a rotor axis and a vane disposed on the downstream side in an axial direction and defining a part of a combustion gas flow passage (Pg) through which combustion gas (G) flows, and seals a gap between the combustor and the vane. The seal member (7) has: an end face (71a) that faces the downstream side in the axial direction so as to face a lateral end face (461) of the vane facing the upstream side in the axial direction; cooling channels (80) through which cooling air is discharged from a plurality of openings (80a) provided in the end face (71a) in an array in a circumferential direction based on the rotor axis; and a clearance forming portion (71b) that protrudes further toward the downstream side in the axial direction than the end face (71a) in which the openings are formed.

摘要： A combustion tube for a gas turbine including an outlet section having a cross-section of an annular sector-shape. The outlet section includes an outer wall forming an outer peripheral boundary of the annular sector-shape, an inner wall forming an inner peripheral boundary of the annular sector-shape, and a pair of side walls forming boundaries on both sides of the annular sector-shape in a circumferential direction, respectively. The outer wall extends obliquely with respect to the inner wall such that a height of the annular sector-shape decreases toward an outlet opening of the combustion tube. A first side wall extends obliquely with respect to a second side such that a perimeter of the annular sector-shape increases toward the outlet opening of the combustion tube. An inclination angle θ1 of the first side wall with respect to the second side wall satisfies 0

摘要： A first-stage stator vane for a gas turbine includes: a first portion partially forming an airfoil which includes a pressure surface, a suction surface, and a trailing edge; and a second portion positioned at a leading-edge side of the airfoil with respect to the first portion, the second portion having a recess portion or a protruding portion. The recess portion or the protruding portion of the second portion has a pair of side wall surfaces, and an angle formed between the pair of side wall surfaces is less than 90 angular degrees.
