Patent number: 11378277Abstract: A combustor includes a circumferential main combustion chamber and a plurality of air inlets, the plurality of air inlets dispersing air into the circumferential main combustion chamber. The combustor also includes at least one swirl-stabilized pilot burner, which disperses combustion gases into the circumferential main combustion chamber. The air inlets and the swirl-stabilized pilot burner are aligned at least partially in a radial direction and at least partially in a circumferential direction.Type: GrantFiled: May 23, 2018Date of Patent: July 5, 2022Assignee: GENERAL ELECTRIC COMPANYInventors: Narendra Digamber Joshi, Shawn David Wehe, ShihYang Hsieh, Changjin Yoon, Owen James Sullivan Rickey, Joseph Douglas Monty

Patent number: 9528880Abstract: A temperature measurement system includes a plurality of filaments. The plurality of filaments are configured to emit thermal radiation in a relatively broad and substantially continuous wavelength band at least partially representative of a temperature of the plurality of filaments. A first and second portion of the filaments has a differing first and a second diameter and/or emissivity, respectively. The system also includes a detector array configured to generate electrical signals at least partially representative of the thermal radiation received from the filaments. The system further includes a controller communicatively coupled to the detector array configured to transform the first electrical signals to a first temperature indication at least partially as a function of the first diameter and/or first emissivity and transform the second electrical signals to a second temperature indication at least partially as a function of the second diameter and/or emissivity.Type: GrantFiled: August 16, 2013Date of Patent: December 27, 2016Assignee: General Electric CompanyInventors: Guanghua Wang, Nirm Velumylum Nirmalan, Ronald Scott Bunker, Todd Garrett Wetzel, Robert Michael Zacharias, Shawn David Wehe, Robert David Briggs

Patent number: 9335215Abstract: A temperature measurement system includes at least one filament configured to emit thermal radiation in a relatively broad and substantially continuous wavelength band that is at least partially representative of a temperature of the at least one filament. The system also includes an optical system configured to receive at least a portion of the thermal radiation emitted from the filament. The optical system includes a wavelength splitting device configured to split the emitted thermal radiation into at least one relatively narrow wavelength band of thermal radiation. The optical system also includes a detector array configured to receive the at least one relatively narrow wavelength band of thermal radiation and to generate electrical signals at least partially representative of the received thermal radiation. The temperature measurement system further includes a controller communicatively coupled to the detector array.Type: GrantFiled: July 31, 2012Date of Patent: May 10, 2016Assignee: General Electric CompanyInventors: Guanghua Wang, Nirm Velumylum Nirmalan, Todd Garrett Wetzel, Ronald Scott Bunker, Robert Michael Zacharias, Shawn David Wehe, Robert David Briggs, Jonathan Edward Slepski

Patent number: 8625098Abstract: A real-time monitoring of an equivalence ratio of a gas-fuel mixture of a gas turbine engine is provided. The system includes multiple optical probes arranged on a plurality of fuel nozzles for transmitting laser beams directly through a gas-fuel mixture or indirectly by reflecting the laser beams from a surface of a centerbody or burner tube of the fuel nozzle. The system also includes one or more detectors to measure the transmitted laser beams from the multiple optical probes. Further, the system includes a data acquisition subsystem for acquiring and processing signals from the one or more detectors to determine the equivalence ratio of the gas-fuel mixture of the nozzle.Type: GrantFiled: December 17, 2010Date of Patent: January 7, 2014Assignee: General Electric CompanyInventors: Hejie Li, Shawn David Wehe, Keith Robert McManus
