Abstract:
A method of operating a gas turbine installation,in which compressed fresh air is branched off after or from a compressor and supplied to an evaporator device, in which, 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, in which the steam/air mixture is fed back upstream of a gas turbine, in which the heat required for the evaporation of the feed water is at least partially extracted from an exhaust gas of the gas turbine, wherein the feed water runs down a wall arrangement heated by the exhaust gas and is subjected to the fresh air, the feed water evaporating and mixing with the fresh air and forming a steam/air mixture, part at least of which is supplied to the gas turbine installation.
