  • COUNTER ROTATED GAS TURBINE FUEL NOZZLES
    Publication number: 20110107765
    Abstract: In certain embodiments, a system includes a gas turbine controller. The gas turbine controller includes a first operational mode enabling fuel flow only through a first plurality of fuel nozzles having a first swirl direction.

  • Combustion System Burner Tube
    Publication number: 20100192580
    Abstract: A combustor includes a burner tube that receives fuel for combustion from a fuel delivery system. An axial swirler is installed in the burner tube. The burner tube is flared downstream of the swirler. The structure provides for improved combustion stability while extending lean blowout and low frequency dynamics margins, which in turn serve to further reduce NOx emissions.
