Patent ID: 8117825

Claim:
A gas turbine installation comprising: at least one turboset including at least one turbine, at least one compressor coupled to the turbine, a gas path connecting the compressor to the turbine, and at least one combustion chamber arranged in the gas path connecting the compressor to the turbine; a flue gas path connected to the turbine, a fresh gas path connected to the compressor, and a recirculation path; at least one flue gas recirculation device configured and arranged, when the gas turbine installation is operating, to pass combustion flue gas from the turbine from the flue gas path, via the recirculation path, to the fresh gas path; a control device configured and arranged to regulate the flow, temperature, or both, of the recirculated combustion flue gases so that a fresh gas/flue gas mixture which enters the compressor is at a predetermined desired temperature; a recirculation cooler configured and arranged to cool the recirculated combustion flue gases, the cooling capacity of which recirculation cooler can be controlled by and which is coupled to the control device, arranged in the recirculation path; wherein the recirculation cooler comprises a water spray cooler which, to cool the recirculated combustion flue gases, is configured and arranged to spray water into the recirculated combustion flue gases.
