Patent number: 9127598Abstract: Ambient air is compressed into a compressed ambient gas flow with a main air compressor. The compressed ambient gas flow having a compressed ambient gas flow rate is delivered to a turbine combustor and mixed with a fuel stream having a fuel stream flow rate and a portion of a recirculated low oxygen content gas flow to form a combustible mixture. The combustible mixture is burned and forms the recirculated low oxygen content gas flow that drives a turbine. A portion of the recirculated low oxygen content gas flow is recirculated from the turbine to the turbine compressor using a recirculation loop. The compressed ambient gas flow rate and the fuel stream flow rate are adjusted to achieve substantially stoichiometric combustion. An excess portion, if any, of the compressed ambient gas flow is vented. A portion of the recirculated low oxygen content gas flow is extracted using an extraction conduit.Type: GrantFiled: August 25, 2011Date of Patent: September 8, 2015Assignee: General Electric CompanyInventors: Daniel David Snook, Lisa Anne Wichmann, Samuel David Draper, Noémie Dion Ouellet

Measurements of a present load may be periodically received from a measuring device and used to periodically recalculate the target load rate. A present load rate may be periodically adjusted by the controller based on the recalculation.Type: ApplicationFiled: November 5, 2012Publication date: May 8, 2014Applicant: GENERAL ELECTRIC COMPANYInventors: Noemie Dion Ouellet, Nathan S.

Patent number: 8516829Abstract: Embodiments of the invention can provide systems and methods for modifying the operation and/or performance of a gas turbine. According to one embodiment, a method for modifying the performance of a gas turbine comprising one or more combustors can be provided. The method can include measuring a gas exhaust temperature for the gas turbine and estimating a heat transfer rate for the gas turbine based at least in part on the gas exhaust temperature. After estimating the heat transfer rate, the method can continue by estimating a transiently accurate combustion reference temperature and using this parameter to control the one or more combustors of the gas turbine. In doing so, the performance of the gas turbine can be modified to ensure reliable and consistent operation.Type: GrantFiled: May 27, 2009Date of Patent: August 27, 2013Assignee: General Electric CompanyInventors: David Ewens, Kevin Wilkes, Christopher Long, Noemie Dion Ouellet

Patent number: 8453462Abstract: At least one main air compressor makes a compressed ambient gas flow. The compressed ambient gas flow is delivered to a turbine combustor at a pressure that is greater than or substantially equal to an output pressure delivered to the turbine combustor from a turbine compressor as at least a first portion of a recirculated gas flow.
