ABSTRACT:
A fully premixed secondary fuel nozzle assembly for use in a gas turbine combustor having multiple combustion chambers, in which the products of the premixed secondary fuel nozzle assembly are injected into the second combustion chamber for supporting a pilot flame and flame transfer between combustion chambers, is disclosed. The improvement includes the elimination of the pilot fuel circuit, which previously served to establish flame in the second combustion chamber. The secondary fuel nozzle assembly includes at least one first injector extending radially outward from the fuel nozzle body for injecting all fuel from the fuel nozzle to mix with compressed air prior to combustion. The first injector can include a plurality of tubes or an annular manifold circumferentially disposed about the nozzle body. Compressed air is drawn into the nozzle body and passes through holes in an injector plate at the tip region to provide cooling.
