Abstract:
A fuel nozzle includes an axial fuel circuit having a converging front surface with an axial fuel outlet formed therein, an air swirler surrounding the axial fuel circuit and having a converging front wall, a swirl chamber bounded by the converging front surface of the axial fuel circuit and the converging front wall of the air swirler, and an air cap surrounding the air swirler, such that an air circuit is defined between the air cap and the air swirler. A plurality of circumferentially disposed discrete jet passages extend through the converging front wall of the air swirler for directing atomizing air from the air circuit to the swirl chamber.
