Patent number: 9803864Abstract: A turbine combustor section has a flow conditioner including a plurality of conduits arranged to convey pressurized air to an air chamber for entrance into a plurality of fuel nozzles. Each conduit includes an inlet configured to receive the pressurized air from an annular passage and an outlet configured to deliver the pressurized air to the air chamber. A cross-sectional area of each conduit varies between the inlet and the outlet so as to reduce a pressure drop across the flow conditioner.Type: GrantFiled: June 24, 2014Date of Patent: October 31, 2017Assignee: General Electric CompanyInventors: Arjun Singh, Chandrasekhar Pushkaran, Nishant Govindbhai Parsania

Patent number: 9739201Abstract: A wake reducing structure for a turbine system includes a combustor liner having an inner surface and an outer surface, the inner surface defining a combustor chamber. Also included is an airflow path located along the outer surface of the combustor liner. Further included is a wake generating component disposed in the airflow path and proximate the combustor liner, wherein the wake generating component generates a wake region located downstream of the wake generating component. Yet further included is an airfoil at least partially disposed in the wake region, the airfoil comprising at least one airfoil hole.Type: GrantFiled: May 8, 2013Date of Patent: August 22, 2017Assignee: General Electric CompanyInventors: Chandrasekhar Pushkaran, Nishant Govindbhai Parsania, Arjun Singh

Patent number: 9719418Abstract: In a turbomachine having an inlet, a compressor, and a turbine, a closed loop sends fluid from a stage of the compressor to a heat exchanger in the turbine and to the inlet. The closed loop heats the fluid, cools the turbine, and delivers heated fluid to the inlet. A mixer can be interposed between the heat exchanger and the inlet to mix fluid from the heat exchanger with compressor discharge fluid, delivering the mixed fluid to the inlet. The mixer can control flow received so that desired temperature and/or flow rate can be provided to the inlet.Type: GrantFiled: April 1, 2013Date of Patent: August 1, 2017Assignee: GENERAL ELECTRIC COMPANYInventors: Prashant Kumar, Sabarinath Devarajan, Vivekanandhan Thiruvettipuram Madhivanan, Indrajit Mazumder, Hemant Puri, Chandrasekhar Pushkaran, Rajarshi Saha

Publication number: 20160047317Abstract: A downstream nozzle for use in a combustor that includes an inner radial wall defining a combustion zone downstream of a primary nozzle and an outer radial wall surrounding the inner radial wall so to form a flow annulus therebetween. The downstream nozzle may include: an injector tube extending between the outer radial wall and the inner radial wall; a first plenum adjacent to the injector tube, and, inboard of the ceiling, a floor disposed between the inner radial wall and the outer radial wall. A feed passage may connect the first plenum to an inlet formed outboard of the outer radial wall and impingement ports may be formed through the floor of the first plenum.Type: ApplicationFiled: August 14, 2014Publication date: February 18, 2016Inventors: Christopher Paul Willis, William Michael Poschel, Lucas John Stoia, Patrick Benedict Melton, Vaibhav Nadkarni, Chandrasekhar Pushkaran

Publication number: 20150338101Abstract: A turbomachine combustor includes a combustor body extending from a head end to a discharge end. The combustor body includes a combustor liner defining a combustion chamber. A combustor sleeve surrounds the combustor liner. The combustor sleeve is spaced from the combustor liner forming a passage. The combustor sleeve includes at least one opening. A baffle is arranged in the passage. The baffle includes a curvilinear surface extending from the combustor sleeve across the at least one opening toward the head end of the combustor body. The baffle is configured and disposed to compress a fluid flow passing through the passage toward the head end.Type: ApplicationFiled: May 21, 2014Publication date: November 26, 2015Applicant: General Electric CompanyInventors: Nishant Govindbhai Parsania, Chandrasekhar Pushkaran
