Patent number: 8355819Abstract: In operating a gas turbine, there can be a difference between the desired heating value of the fuel and the actual needs of the fuel for the supplied fuel to be ignited. In one aspect, fuel parameters related to the molecular weight of the fuel such as specific gravity and pressure drop are determined. Ignitability of the fuel is calculated based on the fuel parameters and adjusted as necessary to bring the fuel's ignitability to designed values. The fuel's ignitability can be calculated without actually igniting the fuel and also without direct knowledge of the fuel's calorific value or its composition.Type: GrantFiled: October 5, 2010Date of Patent: January 15, 2013Assignee: General Electric CompanyInventors: Joseph Kirzhner, Matthieu Paul Frederic Vierling, Nicolas Pourron, Denis Michel Martin

Publication number: 20120048000Abstract: The described method and system utilize continuous and/or periodic measurement of the fuel pipes to detect leakage of fuel. In general, the piping is enclosed in an air-tight containment cover so that a passage is formed between the piping and containment cover. Measurements can be conducted, using known hydrocarbon and other combustible gases industrial analyzers, and leak detectors. Pressure drop within the passage can be compensated by controlling of air inlet flow into the passage, coordinated with the analyzer pumping rate. Temperature and motion of a gas sample can be controlled by heating the inlet air. The system can includes the controlling valves for the leak source localization. The described method and system can be used to analyze and control fuel leak for late lean injection system for combustor of a turbine.Type: ApplicationFiled: August 31, 2010Publication date: March 1, 2012Inventor: Joseph KIRZHNER

Publication number: 20090056342Abstract: A method and system for operating at partial load a gas turbine system having a compressor, a combustor, and a turbine. The method and system may include the steps of lowering a flow of fuel to the combustor, extracting air from the compressor so as to lower a flow of air to the compressor, and returning the extracted air to the turbine or a component of the gas turbine system other than the combustor. Extracting air from the compressor raises a combustion temperature within the combustor. Raising the combustion temperature maintains a combustion exhaust below a predetermined level, maintains stable combustion, and extends turbine turndown values.Type: ApplicationFiled: September 4, 2007Publication date: March 5, 2009Applicant: GENERAL ELECTRIC COMPANYInventor: Joseph Kirzhner

Patent number: 6595436Abstract: The fuel injector includes a solid state actuator that operates through an actuator motion amplifying lever to directly control the needle valve motion. Hydraulic forces, which act along the axes of the needle valve and the motion amplifying lever, are compensated by using a control piston, or other biasing means, to reduce the required amplitude of the control current/voltage and to reduce the required strength of the spring biasing the needle valve closed. The fuel injector may also include a control fuel inlet that is separate from the injection fuel inlet port.Type: GrantFiled: May 8, 2001Date of Patent: July 22, 2003Assignee: Cummins Engine Company, Inc.Inventors: Joseph Kirzhner, Lester Peters, John D.
