ABSTRACT:
A combustor dome assembly having a venturi and an auxiliary wall concentric with the venturi to provide an annular passage for channeling or directing a high velocity air jet from a swirler to a combustion chamber associated with a downstream end of the venturi, thereby facilitating the atomization of a film of water flowing along an inner surface of the venturi and out of the downstream end. In an alternative embodiment, a deflector is used (instead of the auxiliary wall) to direct the air flow towards the downstream end. The downstream end of the venturi may have a curved edge to permit the film of water flowing along an inner surface of the venturi to turn substantially perpendicular to the air flowing past the downstream end of the venturi which further enhances atomization of water. The venturi may also comprise a flange which is positioned in operative relationship with the downstream end for increasing the turbulence at the downstream end. In another embodiment, a plurality of holes are provided in the venturi for permitting natural gas to pass through the venturi and into the annular passage where it can be premixed with swirling air before being introduced to the combustion chamber.
