摘要:
To include a cooling passage leading from a latter stage of a compressor, via an external cooler, to a hollow part provided in a load coupling that couples a rotor of the compressor and a rotor of a turbine to each other, and also leading from the hollow part to the latter stage of the compressor, and a centrifugal compressor that raises air pressure in the hollow part with rotation of the load coupling, in the hollow part. Therefore, pressure of the air in the hollow part is raised by the centrifugal compressor by using a centrifugal force resulting from the rotation of the load coupling at the time of operating the gas turbine. Cooled air flows from the hollow part to between compressor rotor blades and compressor vanes at the latter stage, and then flows into the hollow part, thereby enabling to efficiently reduce temperature in the hollow part.

A variable vane drive device includes a movable ring disposed at an outer circumferential side of a casing of an axial-flow compressor and having an annular shape, four ring support mechanisms disposed at intervals in a circumferential direction of the movable ring and rotatably supporting the movable ring around a rotor, and a link mechanism for connecting the movable ring to a variable vane such that a direction of the variable vane is varied by rotation of the movable ring. The ring support mechanisms have inner rollers, outer rollers, and roller support bases for rotatably supporting the inner rollers and the outer rollers in a state in which the movable ring is sandwiched between the inner roller and the outer rollers.
