Abstract:
1. A system for supplying a working fluid to a combustor, comprising: a. a liner defining a combustion chamber within the combustor; b. a flow sleeve that circumferentially surrounds at least a portion of the liner; and c. a tube that extends through the flow sleeve and the liner, the tube having an inner wall radially spaced from an outer wall, an inlet axially spaced from an outlet and a fluid passage defined within the tube between the inner and outer walls, the fluid passage being in fluid communication with a fuel passage, the inlet being in fluid communication with a compressed air supply and the outlet being in fluid communication with the combustion chamber; d. wherein the tube defines a first set of injectors annularly arranged within the tube and angled radially with respect to an axial centerline of the tube, each injector providing for fluid communication of the working fluid through the outer wall and the inner wall, wherein the tube further defines at least one fuel port disposed within each injector of the first set of injectors between the outer and inner walls, and wherein each fuel port is in fluid communication with the fluid passage.
