Patent number: 11940152Abstract: A fuel injector includes a forward end wall and an aft end wall. The fuel injector further includes side walls that extend between the forward end wall and the aft end wall. The forward end wall, the aft end wall, and the side walls collectively define an opening for passage of air. At least one fuel injection member is disposed within the opening and extends between the end walls. A fuel circuit is defined within the fuel injector. The fuel circuit includes an inlet plenum defined within the forward end wall of the fuel injector. The fuel circuit further includes a fuel passage that extends from, and is in fluid communication with, the inlet plenum. The fuel passage is defined within the at least one fuel injection member. The fuel passage has a cross-sectional area that varies along a length of the fuel injection member.Type: GrantFiled: October 27, 2022Date of Patent: March 26, 2024Assignee: GE Infrastructure Technology LLCInventors: Andrew Grady Godfrey, Marissa Singley Garcia, Jun Cai

Patent number: 10851999Abstract: A fuel injector is provided for the radial introduction of a fuel/air mixture to a combustor. The fuel injector includes a frame having interior sides defining an opening for passage of a first fluid; at least one fuel injection body; and a conduit fitting. The at least one fuel injection body is coupled to the frame and positioned within the opening, thereby defining flow paths for the first fluid. The at least one fuel injection body defines a fuel plenum, and a set of fuel injection holes are defined through an outer surface of the at least one fuel injection body. The conduit fitting is coupled to the frame and conveys fuel from a fuel supply line to the fuel plenum. Fuel and the first fluid mix in the flow paths and are delivered through the outlet to the combustor.Type: GrantFiled: October 9, 2017Date of Patent: December 1, 2020Assignee: General Electric CompanyInventors: Jun Cai, Andrew Grady Godfrey, Richard Martin DiCintio, Seth Reynolds Hoffman, Ronnie Ray Pentecost, Jayaprakash Natarajan, Wei Zhao

Patent number: 10344978Abstract: The present disclosure is directed to a combustor having an annularly shaped liner that at least partially defines a hot gas path of the combustor. A flow sleeve circumferentially surrounds at least a portion of the liner. The flow sleeve is radially spaced from the liner to form a cooling flow annulus therebetween. A bluff body extends radially between the flow sleeve and the liner through the cooling flow annulus. A guide vane is disposed within the cooling flow annulus and extends between the flow sleeve and the liner proximate to the bluff body.Type: GrantFiled: March 15, 2016Date of Patent: July 9, 2019Assignee: General Electric CompanyInventors: Andrew Grady Godfrey, Christopher Paul Willis, David William Cihlar, David Philip Porzio

Patent number: 10203114Abstract: A sleeve assembly for a combustion system is provided. The sleeve assembly includes a liner defining a combustion chamber having a flow axis and a primary combustion zone. The liner has a forward end and an aft end such that the liner circumscribes the flow axis. The sleeve assembly also includes a shell circumscribing the liner such that a cooling duct is defined between the liner and the shell. The shell includes a unisleeve having a forward end and an aft end. The aft end of the unisleeve is positioned axially upstream of the aft end of the liner, defining a gap between the aft end of the liner and the aft end of the unisleeve. The unisleeve is mounted to the liner at circumferentially spaced locations along an axial plane between the forward end and the aft end of the unisleeve.Type: GrantFiled: March 4, 2016Date of Patent: February 12, 2019Assignee: General Electric CompanyInventors: David William Cihlar, Jonathan Hale Kegley, Andrew Grady Godfrey, Christopher Paul Willis

Publication number: 20170268776Abstract: The present disclosure is directed a combustor. The combustor includes an annularly shaped liner having a downstream end that is rigidly connected to an aft frame. A flow sleeve circumferentially surrounds at least a portion of the liner and is radially spaced from the liner to form a cooling flow annulus therebetween. A plurality of fuel injector assemblies is circumferentially spaced about the flow sleeve. Each fuel injector assembly extends radially through the flow sleeve and the liner. Each fuel injector assembly is rigidly connected to the flow sleeve and to the liner. An aft portion of the flow sleeve terminates axially short of the aft frame to form an axial gap between the aft end and the aft frame to allow for unrestrained axial expansion and contraction of the aft end.Type: ApplicationFiled: March 15, 2016Publication date: September 21, 2017Inventors: Christopher Paul Willis, David William Cihlar, Jonathan Hale Kegley, Andrew Grady Godfrey, David Philip Porzio

Publication number: 20130074505Abstract: A system includes a gas turbine combustor. The gas turbine combustor includes a combustion liner disposed about a combustion region and a sleeve disposed about the combustion liner. The combustion liner and the sleeve define an airflow passage circumferentially about the liner. The gas turbine combustor also includes multiple axial injectors configured to direct an airflow into the airflow passage in an axial direction facilitating a momentum exchange between an injection flow and a crossflow from an upstream portion of the combustor. The multiple axial injectors are asymmetrically configured to provide an uniform injection of the airflow circumferentially about an axis of the gas turbine combustor.Type: ApplicationFiled: September 22, 2011Publication date: March 28, 2013Applicant: General Electric CompanyInventors: David Kaylor Toronto, Carolyn Ashley Antoniono, Andrew Grady Godfrey
