Abstract
A tangential air entry fuel nozzle has a longitudinal axis and two cylindrical-arc scrolls with the centerline of each offset from that of the other. Overlapping ends of these scrolls form an air inlet slot therebetween for the introduction of an air/fuel mixture into the fuel nozzle. A combustor-end endplate has a central opening to permit air and fuel to exit into a combustor, while at the opposite end another endplate blocks the nozzle flow area. The scrolls are secured between these endplates. A centerbody is located between the scrolls coaxial with the axis. The centerbody has a base which includes at least one air supply port extending therethrough, and an internal passageway. The centerbody includes a frustum portion and aerodynamic ramps that prevent flow reversal and flame stabilization between the endplates.
