Document Type and Number:
Japanese Patent JP6932006
Kind Code:
B2
Abstract:
A bundled tube fuel nozzle 100 includes a forward plate 106, a first intermediate plate 108 and an outer sleeve 114 defining a fuel plenum 116, a second intermediate plate 110 axially spaced from the first intermediate plate 108 where the first intermediate plate 108, the second intermediate plate 110 and the outer sleeve 114 define a purge air plenum 120, an aft plate 112 axially spaced from the second intermediate plate 110 where the second intermediate plate 110, the aft plate 112 and the outer sleeve 114 define a cooling air plenum 128 and an annular wall 124 that extends from the second intermediate plate 110 to the aft plate 112. The annular wall 124 defines a cooling flow channel 126 within the bundled tube fuel nozzle 100. A plurality of apertures 150 is defined proximate to a cool side of the aft plate 112 and provide for fluid communication between the cooling flow channel 126 and the cooling air plenum 128.
