<P>PROBLEM TO BE SOLVED: To provide a fluid cooled injection nozzle assembly for a gas turbomachine. <P>SOLUTION: The fluid cooled injection nozzle assembly 38 for the turbomachine includes an inner conduit portion that includes a body portion having a first end portion 127 and extending to a tip end portion. The body portion includes an outer surface and an inner surface. A cooling element 140 extends through the inner conduit portion. The cooling element 140 includes a body element 144 having a first end section and extending to a second end section 148. The body element 144 includes an outer surface and an inner surface that defines a cooling passage. The outer surface of the body element 144 is spaced from the inner surface of the inner conduit portion to define a return channel. Fluid passing through the cooling passage 153 impinges upon and convectively cools the tip end portion 128, enters the return channel, and is directed out from a nozzle member 94. <P>COPYRIGHT: (C)2012,JPO&INPIT |
