ABSTRACT:
A combustible fuel containing 3% to 45% of the fuel needed to operate a gas turbine is introduced into the compressor air stream for the gas turbine. The mixed fuel and air stream is introduced to the gas turbine prior to the combustor stage through a pipe, orifice or nozzle. The mixed air and fuel stream serves to reduce the nitrogen oxide emissions of the gas turbine. Waste air streams such as mine ventilation air may be used as the mixed fuel and air stream.
