  • Publication number: 20180328587
    Abstract: A fuel injector includes a frame and a pair of fuel injection bodies coupled to the frame. The frame has interior sides that define an opening for passage of a first fluid. Inlet flow paths for the first fluid are defined at least between the interior sides of the frame and the respective fuel injection bodies. Each fuel injection body defines a fuel plenum and includes at least one fuel injection surface that defines a plurality of fuel injection holes in communication with the fuel plenum. An outlet member is located downstream of, and in fluid communication, with the inlet flow paths. The outlet member is configured to produce discrete outlet flow paths exiting the outlet member via struts, flow diverters, and/or separate outlet members.

  • Publication number: 20180328588
    Abstract: A fuel injector is provided for the radial introduction of a liquid fuel/air mixture to a combustor. The fuel injector includes a body having a frame that defines an inlet portion and an outlet member that defines an outlet portion. A fuel plenum is defined within the outlet member, and a fuel injection port, which communicates with the fuel plenum, is defined through the outlet member. A fuel supply conduit, fixed to the body, communicates between a source of liquid fuel and the fuel injection port, via the fuel plenum. Alternately, the fuel injector may include a swirl-inducing device mounted to the outlet member in communication with the fuel injection port, and a fuel supply conduit fixed to the swirl-inducing device. In this embodiment, the fuel supply conduit communicates between the fuel injection port and a source of a liquid fuel and water mixture, via the swirl-inducing device.
