Abstract
A spray nozzle comprising a nozzle body and a swirl chamber in the nozzle body, the swirl chamber extending axially from a back wall of the swirl chamber to a discharge orifice axially opposite the back wall. The nozzle further comprises a plurality of fluid channels opening to the swirl chamber for conveying fluid from an inlet to the swirl chamber. The fluid channels are disposed to cause swirling of the fluid within the swirl chamber for discharge through the discharge orifice to form a conical spray, and the fluid channels each have a center line projection thereof at least partially radially overlapping the discharge orifice. This construction enables the formation of higher density streaks in the conical spray, which higher density streaks have higher kinetic energy than the lower density mist of the conical spray between the streaks for improved penetration into an air stream, as may be desired for mixing fuel with combustion air, as in a gas turbine combustion system.
