Patent ID: 8234871

Claim:
A nozzle assembly comprising: a nozzle having discrete combustion air passages extending from a first, upstream end to a second, downstream end; a fuel distribution manifold disk attached to the first, upstream end of the nozzle having a central opening extending therethrough and having discrete combustion air passages extending from a first, upstream end to a second, downstream end corresponding to, and in alignment with, the discrete combustion air passages in the nozzle; fuel distribution grooves located in one end of the fuel distribution manifold disk extending from the central opening to the discrete combustion air passages to define a fuel circuit; a fuel circuit cover having discrete combustion air passages extending from a first, upstream end to a second, downstream end corresponding to, and in alignment with, the discrete combustion air passages in the fuel distribution manifold disk and operable to close the fuel distribution grooves to thereby define fuel passages extending from the central opening to the discrete combustion air passages; and a fuel delivery channel in communication with the central opening and the fuel passages for delivery of fuel to the combustion air in the discrete combustion air passages.
