Abstract
A bundled tube fuel nozzle includes a forward plate, a first intermediate plate and an outer sleeve defining a fuel plenum, a second intermediate plate axially spaced from the first intermediate plate where the first intermediate plate, the second intermediate plate and the outer sleeve define a purge air plenum, an aft plate axially spaced from the second intermediate plate where the second intermediate plate, the aft plate and the outer sleeve define a cooling air plenum and an annular wall that extends from the second intermediate plate to the aft plate. The annular wall defines a cooling flow channel within the bundled tube fuel nozzle. A plurality of apertures is defined proximate to a cool side of the aft plate and provide for fluid communication between the cooling flow channel and the cooling air plenum.
