Patent number: 10502426Abstract: 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.Type: GrantFiled: May 12, 2017Date of Patent: December 10, 2019Assignee: General Electric CompanyInventors: Donald Timothy Lemon, Gilbert Otto Kraemer, Wei Chen, Marcus Byron Huffman, Ronnie Ray Pentecost

Patent number: 8484978Abstract: A method of assembling a fuel nozzle assembly for a gas turbine engine having a natural operating frequency includes providing a flange and providing a premix tube. The flange is fabricated from a first alloy such that the flange is configured to exhibit a first frequency that is different than the natural operating frequency of the gas turbine engine. The premix tube is fabricated from a second alloy such that the premix tube is configured to exhibit a second frequency that is different from the natural operating frequency of the gas turbine engine. The premix tube is coupled to the flange.Type: GrantFiled: November 12, 2009Date of Patent: July 16, 2013Assignee: General Electric CompanyInventors: Donald Mark Bailey, Scott Robert Simmons, Marcus Byron Huffman
