Abstract
To provide a combined-cycle power generation plant heat exchanged effectively in an exhaust heat, the recovery boiler is increased by suppressing on reducing the swirl present in the exhaust gas of a gas turbine. That is, a plurality of stationary blades 10 are arranged on the surface of a rear inner barrel in the circumferential direction of the rear inner barrel to partition an annular channel formed between a casing and the rear inner barrel. Thereby, it is possible to uniform the flow of exhaust gas with a low pressure drop.
