A fuel nozzle assembly for a gas turbine includes a plurality of circumferentially spaced vanes with holes for flowing fuel from plenums within the vanes through holes in the vane walls for premixing with air. To tune the nozzle assembly, the holes are resized by reforming the existing holes to a predetermined hole size, securing plugs into the holes, and forming holes through at least certain of the plugs to diameters less than the diameter of the existing holes.
In a fuel nozzle assembly for a gas turbine having a plurality of circumferentially spaced vanes with holes through walls of the vanes for flowing fuel for premixing with air within the nozzle assembly, a method of tuning the fuel nozzle assembly by changing existing areas of the premix fuel holes in the vane walls comprising the steps of:
