Abstract
A method is provided for operating a gas turbine power plant with flue gas recirculation, in which the flue gases are split into a first flue gas flow for recirculation into an intake flow of the gas turbine and into a second flue gas flow for discharging to the environment. The first flue gas flow is cooled in a recooler before its mixing with ambient air for forming the intake flow. The recirculation flow, after being recooled, is reheated in order to avoid condensation of vaporous water contained in the recycled flue gases during cooling as a result of the mixing with the ambient air. A gas turbine power plant is provided with flue gas recirculation, which includes a heat exchanger for reheating the recirculation flow after being recooled.
