ABSTRACT:
An elongate igniter is disposed in the inner air chamber of an air blast nozzle coaxial with the longitudinal axis thereof such that the discharge tip of the igniter discharges a spark generally longitudinally downstream of the tip out of the path of swirling inner air flow and in the path of a reverse flow field of atomized fuel established downstream of the tip by relatively controlled inner and outer air swirl strengths.
