| 摘要 |
A method of operating a gas-turbine power plant is described, having a gas-turbine plant (1) 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 (8) to a waste heat boiler (4), from which the cooled exhaust gas (9) is fed to an outlet (10) and then to the free atmosphere. The invention is characterized in that a specific reduction in the flow velocity with which the exhaust gas (9) flows through the outlet (10) is effected in the region of the latter, with a simultaneous pressure increase downstream in the outlet (10), and in that the pressure conditions occurring inside the outlet (10) are transmitted free of losses between the gas turbine (1) and the outlet (10) via a gas-tight flow path of the hot and exhaust gases (8; 9).
