<p>A fuel nozzle assembly for a gas turbine includes a plurality of circumferentially spaced vanes with holes (24), (26) for flowing fuel from plenums within the vanes through holes in the vane walls (30), (31) for premixing with air. To tune the nozzle assembly, the holes (24), (26) are resized by reforming the existing holes to a predetermined hole size, securing plugs (52), (54) in the holes, and forming holes (60), (62), (64) through at least certain of the plugs (52), (54) to diameters less than the diameter of the existing holes (24), (26).</p> |
