ABSTRACT:
A gas turbine system composed of a gas turbine engine and a controller. The gas turbine engine includes an annular combustor, and a turbine driven by combustion gas from the annular combustor to rotate on a longitudinal centerline axis of the gas turbine engine. The annular combustor is comprised of an outer casing, a liner disposed in the outer casing, and a plurality of dilution air regulators introducing dilution air into the liner. The plurality of dilution air regulators are circumscribed about the longitudinal centerline axis and spaced apart at substantially equal intervals. The controller controls the plurality of dilution air regulators to individually adjust dilution air flows through the plurality of dilution air regulators into the liner.
