ABSTRACT:
The quantity of NOx emissions generated by a combined gas turbine-steam boiler power plant is controlled by recycling a controlled amount of the steam boiler exhaust gas to the air compressor of the gas turbine such that the recycled gases constitutes up to about 30% of the fluid flowing through the air compressor and by cooling the recycled steam boiler exhaust gases to about the desired gas turbine compressor inlet temperature prior to its introduction into the air compressor.
