Abstract
A method of operating a gas-turbine power plant is described, having a gas-turbine plant ( ) in which an oxygen-containing gas is drawn in, compressed and fired and, after passing through a turbine stage, is fed as discharging hot gas ( ) to a waste heat boiler ( ), from which the cooled exhaust gas ( ) is fed to an outlet ( ) and then to the free atmosphere. The invention is characterized in that a specific reduction in the flow velocity with which the exhaust gas ( ) flows through the outlet ( ) is effected in the region of the latter, with a simultaneous pressure increase downstream in the outlet ( ), and in that the pressure conditions occurring inside the outlet ( ) are transmitted free of losses between the gas turbine ( ) and the outlet ( ) via a gas-tight flow path of the hot and exhaust gases ( ).
