Abstract
A gas turbine installation (), in particular in a power plant for generating electricity, includes a turboset () having a turbine (), a compressor () and a combustion chamber () arranged in a gas path () connecting the compressor () to the turbine (), and a flue gas recirculation device (), which passes combustion flue gas from the turbine () from a flue gas path () connected to the turbine () via a recirculation path () to a fresh gas path () connected to the compressor (). To improve the efficiency of the gas turbine installation (), a control device () controls a volumetric flow and/or a temperature of the recirculated combustion flue gases in such a way that a fresh gas/flue gas mixture which enters the compressor () is at a predetermined desired temperature.
