ABSTRACT:
An exhaust-side bearing rotatably supports a rotor of a turbine. A seal air-pipe and a first air-supply pipe supply compressed air extracted from a compressor of the turbine to the exhaust-side bearing. A second air-supply pipe supplies compressed air from a supplementary air-source to the exhaust-side bearing. A control apparatus switches between the first air-supply pipe and the second air-supply pipe based on the operation state of the gas turbine.
