Abstract
A fuel nozzle including vortex generating features for use in a combustion turbine engine is provided. An array of inner pre-mixing conduits () extends between an inlet end () and an outlet end () of the nozzle. An array of outer pre-mixing conduits () may be disposed radially outwardly relative to the inner pre-mixing conduits (). A fuel-directing tube () includes fuel-directing arms () structured to direct fuel flow into the outer pre-mixing conduits () to be mixed with a flow of air. The fuel-directing arms include a bluff structural arrangement () that may be disposed upstream of fuel injection locations (') into the outer pre-mixing conduits (). The proposed nozzle is believed to provide superior micro-mixing capability, such as by increasing the depth of penetration of jets of fuel in a cross-flow of air, and/or formation of vortices in a wake zone downstream from the vortex generating features.
