Abstract:
A structure for supporting turbine nozzles (13) and shrouds (21) opposing rotor blades adjacent to the nozzles by means of a turbine casing (23) covering a turbine (5) in a gas turbine. The front and back end parts of a circumferential flange (19) of each nozzle engage an inner circumferential part of the turbine casing (23), a front-end part of the shrouds (21) engages the back-end part of the circumferential flange (19) in front of that front-end part, and a back-end part of the shrouds (21) engages the front-end part of the circumferential flange (19) in back of that back-end part. The nozzles and the shrouds are supported by the turbine casing by means of support pins (51) which penetrate an overlapping engagement portion (49) wherein the engaging part of the turbine casing, the engaging part of the circumferential flanges, and the engaging part of the shrouds overlap each other in the radial direction.
