Abstract
An atomizer for use with a combustor in a gas turbine has a body with a fuel passageway extending through the center of the body. A plurality of channels extends within the body about the passageway centerline, and are oriented along a circumferential angle about the passageway centerline to deliver air at the discharge end of the passageway with an axially whirling motion. The channels are simultaneously oriented along an axial angle about the passageway centerline, thereby directing the flow of air to converge toward the passageway centerline, mix with the fuel, and then at least in part diverge from the passageway centerline. The whirling air intersects with the fuel at the exit of the nozzle to effectively atomize both the air and fuel thereby providing a homogeneous air/fuel mixture to the combustion chamber.
