Patent number: 8534075Abstract: A method of regulating the Wobbe number of a multi-composition gas fuel supplied to one or more combustors of a gas turbine includes: (a) providing a control system for regulating fuel and air flow to the one or more combustors; and (b) reforming a fraction of the gas fuel upstream of the one or more combustors to form hydrogen and carbon monoxide to be supplied to the one or more combustors with a remaining fraction of the fuel; wherein the fraction of fuel reformed is adjusted to maintain the Wobbe number of the fuel supplied to the one or more combustors within a predetermined range.Type: GrantFiled: May 31, 2011Date of Patent: September 17, 2013Assignee: General Electric CompanyInventors: Willy S. Ziminsky, Gilbert O. Kraemer, Girard A. Simons, Mark A. Hadley

Patent number: 8443607Abstract: An air/fuel premixer comprising a peripheral wall defining a mixing chamber, a nozzle disposed at least partially within the peripheral wall comprising an outer annular wall spaced from the peripheral wall so as to define an outer air passage between the peripheral wall and the outer annular wall, an inner annular wall disposed at least partially within and spaced from the outer annular wall, so as to define an inner air passage, and at least one fuel gas annulus between the outer annular wall and the inner annular wall, the at least one fuel gas annulus defining at least one fuel gas passage, at least one air inlet for introducing air through the inner air passage and the outer air passage to the mixing chamber, and at least one fuel inlet for injecting fuel through the fuel gas passage to the mixing chamber to form an air/fuel mixture.Type: GrantFiled: February 20, 2009Date of Patent: May 21, 2013Assignee: General Electric CompanyInventors: William D. York, Willy S. Ziminsky, Benjamin P. Lacy

Patent number: 8371101Abstract: A combustor may include an interior flow path therethrough, a number of fuel nozzles in communication with the interior flow path, and an inlet guide vane system positioned about the interior flow path to create a swirled flow therein. The inlet guide vane system may include a number of windows positioned circumferentially around the fuel nozzles. The inlet guide vane system may also include a number of inlet guide vanes positioned circumferentially around the fuel nozzles and adjacent to the windows to create a swirled flow within the interior flow path.Type: GrantFiled: September 15, 2009Date of Patent: February 12, 2013Assignee: General Electric CompanyInventors: Baifang Zuo, Derrick Simons, William York, Willy S. Ziminsky

Patent number: 8240150Abstract: A nozzle for a gas turbine combustor includes a first radially outer tube defining a first passage having an inlet and an outlet, the inlet adapted to supply air to a reaction zone of the combustor. A center body is located within the first radially outer tube, the center body including a second radially intermediate tube for supplying fuel to the reaction zone and a third radially inner tube for supplying air to the reaction zone. The second intermediate tube has a first outlet end closed by a first end wall that is formed with a plurality of substantially parallel, axially-oriented air outlet passages for the additional air in the third radially inner tube, each air outlet passage having a respective plurality of associated fuel outlet passages in the first end wall for the fuel in the second radially intermediate tube.Type: GrantFiled: August 8, 2008Date of Patent: August 14, 2012Assignee: General Electric CompanyInventors: Balachandar Varatharajan, Willy S. Ziminsky, John Lipinski, Gilbert O. Kraemer, Ertan Yilmaz, Benjamin Lacy

Publication number: 20100162711Abstract: The primary nozzles of a Dry Low NOx (DLN) combustor are configured to alternatively burn a first gas fuel or a second gas fuel, where the two gas fuels may have widely disparate energy content. Natural gas may be the first gas fuel and syngas may be the second gas fuel. An inner fuel circuit and an outer fuel circuit are provided to allow effective control of fuel/air mixing profiles, dynamics, primary pre-ignition and emission control by changing the fuel split between the two fuel circuits. The inner fuel circuit may be run in a diffusion combustion mode on many gas fuels.Type: ApplicationFiled: December 30, 2008Publication date: July 1, 2010Inventors: Baifang Zuo, Willy S. Ziminsky, Gilbert Otto Kraemer, Abdul Rafey Khan, Christian X. Stevenson, Chunyang Wu
