Abstract:
An integrated power plant, comprising a gas-turbine set with a compressor, a combustion chamber and a gas turbine, hot exhaust gases of said gas turbine flowing through a heat-recovery boiler arranged downstream of said gas turbine to exit the power plant after having passed said heat recovery boiler, and a water/steam circuit with a steam generator which is fired separately by burning a carbon-containing fuel with fresh combustion air not being part of said hot exhaust gases of said gas turbine, said steam generator having a flue-gas NOx-reduction unit arranged downstream of the steam generator, the heat-recovery boiler being incorporated in the water/steam circuit, wherein a branch line is provided at the heat-recovery boiler, by means of which branch line a predetermined portion of the exhaust gases coming from the gas-turbine set and flowing through the heat-recovery boiler is branched off and is added upstream of the flue-gas NOx-reduction unit to the flue gases flowing through the steam generator.
