Abstract:
A gas-turbine power plant, comprising:a device for compressing an oxygen-containing gas; at least one combustion chamber for heating the compressed gas in fluid communication with said device for compressing; an outlet in fluid communication with said at least one combustion chamber and including a flow-limiting wall; a diffuser arranged at a position in the flow direction downstream of the outlet; at least one gas turbine in fluid communication with said at least one combustion chamber and including a flow path, an exit, and working stages, in which turbine hot gas produced expands to perform work and is then transferred into the flow path in which it passes through the working stages, and discharged into the atmosphere via the outlet; a displacement body integrated at least approximately centrally in the cross section of flow in the region of the outlet, the displacement body having a spatial form so that it achieves a diffuser effect in interaction with the flow-limiting wall; and wherein the flow path between the exit of the gas turbine and the outlet is essentially gas-tight relative to the atmosphere.
