Abstract

See full text

An integrated power plant comprises a gas-turbine set with a compressor, a combustion chamber and a gas turbine, a heat-recover boiler arranged downstream of the gas turbine, and a water/steam circuit with a steam turbine, a condenser, a feedwater tank and a separately fired steam generator having a flue-gas NOx-reduction unit arranged on the flue-gas side downstream of the steam generator, the heat-recovery boiler for the generation of steam being incorporated in the water/steam circuit. In such a power plant, in order to improve the part-load behavior, 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 can be branched off and added upstream of the flue-gas NOx-reduction unit to the flue gases coming from the steam generator.
