Abstract
The invention relates to a method of operating a gas turbine installation ( ), compressed fresh air ( ) is branched off after a compressor ( ) and supplied to an evaporator device ( ), in the evaporator device ( ) feed water ( ) is evaporated, while heat is supplied, and is mixed with the fresh air ( ) in order to generate a steam/air mixture ( ), the steam/air mixture ( ) is fed back upstream of a gas turbine ( ), the heat required for the evaporation of the feed water ( ) is at least partially extracted from an exhaust gas ( ) of the gas turbine ( ). In order to improve the efficiency of the gas turbine installation ( ), the feed water ( ) runs down along a wall arrangement ( ) heated by the exhaust gas ( ) and is subjected to the fresh air ( ). The feed water ( ) evaporates and mixes with the fresh air ( ), by which means the steam/air mixture ( ) forms for the recirculation.
