ABSTRACT:
An air blast nozzle includes a ring of air swirler vanes therein for producing a first turbulent flow of air therethrough and a turbulence generator located within the air flow through said swirler vanes to produce an intensification of the turbulent flow of the air swirl produced by the swirler vanes. The intensified swirled air is immediately directed into mixed flow relationship with fuel from said air blast nozzle to maintain increased turbulence intensity at the fuel from said nozzle without attenuation of the air energy level prior to burning of the air/fuel mixture so as to improve combustor efficiency by evaporation rate control due to decreased fuel droplet size attributable to the turbulence intensification.
