A duct leading to a bypass and a duct leading to a heat exchanger are arranged at the output side of the gas turbine. The two ducts can be closed alternately by flaps. Pivotable guide plates are arranged in the branching area of the two ducts. The guide plates are pivoted by linkages connected to the flaps in the duct leading to the heat exchanger, so that, when the flaps in the bypass are open, the guide plates are inclined relative to the flow of combustion gases and deflect the flow into the duct leading to the bypass. When the flaps in the duct leading to the bypass are closed, the guide plates are pivoted to extend parallel to the flow of combustion gases. In this position, the guide plates do not provide any resistance to the flow of combustion gases to the heat exchanger.
