Patent number: 8578717Abstract: A method is described for controlling load variations in a gas turbine. The method comprises reducing the flow of gaseous fuel entering the combustor to a predefined minimum value, if an increase is observed in the rotation regime of said turbine above a predefined maximum value and a total reduction in the load, activating a selective feeding sequence of the burners if the turbine is operating in normal functioning or premixed flame mode, modifying the angulation of the adjustable stator vanes, in order to reduce the speed rate of the compressor, and opening one or more anti-surge valves and one or more overboard bleeds, in order to reduce the air flow at the inlet of the combustor.Type: GrantFiled: December 11, 2008Date of Patent: November 12, 2013Assignee: Nuovo Pignone S.p.A.Inventors: Giovanni Tonno, Mariateresa Paci, Michele D'Ercole, Alessandro Russo, Jesse F.

Patent number: 8285468Abstract: Embodiments of the invention can provide systems and methods for using a combustion dynamics tuning algorithm with a multi-can combustor. According to one embodiment of the invention, a method for controlling a gas turbine engine with an engine model can be implemented for an engine comprising multiple cans. The method can include obtaining operating frequency information associated with multiple cans of the engine. In addition, the method can include determining variation between operating frequency information of at least two cans. Furthermore, the method can include determining a median value based at least in part on the variation. Moreover, the method can include determining whether the median value exceeds at least one operating threshold. The method can also include implementing at least one engine control action to modify at least one of the operating frequencies if at least one operating threshold is exceeded.Type: GrantFiled: February 4, 2011Date of Patent: October 9, 2012Assignee: General Electric CompanyInventors: Giovanni Tonno, Mariateresa Paci, Jesse Floyd Stewart, Antonio Asti

Patent number: 7730726Abstract: A method and apparatus are described for controlling the combustion in a gas turbine. The method includes measuring, with one or two calorimeters, the temperature, calorific value and relative density of a gaseous fuel in order to determine the Wobbe index, comparing the Wobbe index value measured with a predefined Wobbe index value for the gaseous fuel and regulating the temperature of the gaseous fuel with at least one heat exchanger in order to reach the predefined Wobbe index value. The method may also include using a second gaseous fuel, having a different Wobbe index from the gaseous fuel, or a fuel obtained by mixing the gaseous fuel and the second gaseous fuel, according to arbitrary proportions and variable with time.Type: GrantFiled: May 7, 2008Date of Patent: June 8, 2010Assignee: Nuovo Pignone S.p.A.Inventors: Antonio Asti, Mariateresa Paci, Michele D'Ercole, Massimo Betti, Simone Bei, Giovanni Tonno, Jesse Stewart, Francesco Maria Orgero

Publication number: 20090158747Abstract: A method is described for the controlled purging of the fuel feeding system in the combustor of a gas turbine comprising at least one compressor, capable of compressing the air introduced into it through an inlet duct, at least one combustor, in which said compressed air is mixed and combusted with a gaseous fuel coming from a feeding duct, and at least one turbine, capable of transforming the energy of the combusted gas coming from said combustion chamber into work energy which can be exploited for activating one or more operating machines. The combustor is equipped with one or more burners, each equipped with at least one pilot injector and one or more main injectors for the adduction of the gaseous fuel inside the burner. The method comprises purging at least part of the main injectors and relative manifolds with a stream of gaseous fuel when the turbine is in diffusive flame functioning mode.Type: ApplicationFiled: December 16, 2008Publication date: June 25, 2009Inventors: Giovanni TONNO, Antonio ASTI, Antonio BALDASSARRE, Massimo BETTI, Michele D'ERCOLE, Mariateresa PACI, Stefano RIVA, Jesse STEWART
