Disclosed is a process of fabricating a fuel nozzle assembly. The process includes providing a fuel nozzle end cover, positioning a fuel nozzle ring having a stepped geometry within a cavity of the fuel nozzle end cover, and securing the fuel nozzle ring to the fuel nozzle end cover by welding or brazing to form features corresponding to one or more of the fuel nozzle end cover and a fuel nozzle insert. The process further includes securing the fuel nozzle insert to the fuel nozzle cover by direct contact with the fuel nozzle ring.

A unitary fuel injection manifold for a secondary fuel nozzle improves fuel-air mixing and offers flexibility to alter the mixing profile through adaptability to a variety of number, types, and orientation of discharge outlets to the combustion air mixing space around the secondary fuel nozzle. An aerodynamic surface with reduced extension into the mixing space reduces pressures drop and interference with design airflow. Manifold integrity is enhanced by elimination of fillet welds to mount external pegs.
