  • Patent number: 4884746
    Abstract: A fuel nozzle having two concentric flow paths, the interior flow path comprising a first swirl chamber having a first diameter, an exit chamber having a second diameter selected to be smaller than the first diameter, and a convergent section joining the first swirl chamber and the exit chamber. The exterior flow path comprises an annular second swirl chamber formed about the periphery of the exit chamber. The interior flow path has a fuel and air mixture flowing therethrough while the exterior flow path has air only flowing therethrough. Fuel in the interior flow path is caused to lie in a film and flow circumferentially about the internal wall of the first swirl chamber by air entering into the first swirl chamber through inlet holes which are configured to direct the air tangentially along the internal wall surface of the first swirl chamber.
