Patent number: 11035247Abstract: A turbine apparatus is disclosed including a first article and a second article disposed between the first article and a hot gas path of a turbine. The first article includes at least one first article cooling channel in fluid communication with and downstream from a cooling fluid source, and the second article includes at least one second article cooling channel in fluid communication with and downstream from the at least one first article cooling channel. A method for redundant cooling of the turbine apparatus is disclosed including flowing a cooling fluid from the cooling fluid source through at least one first article cooling channel, exhausting the cooling fluid from the at least one first article cooling channel into at least one second article cooling channel, and flowing the cooling fluid through the at least one second article cooling channel.Type: GrantFiled: April 1, 2016Date of Patent: June 15, 2021Assignee: GENERAL ELECTRIC COMPANYInventors: Matthew Troy Hafner, Scott Francis Johnson, James Joseph Murray

Patent number: 9482579Abstract: Various embodiments include systems and apparatuses adapted for detecting two-dimensional turbomachine exhaust temperature. In some embodiments, a system includes a two-dimensional grid sized to mount within an exhaust path of a gas turbomachine, a radiation detection device for detecting radiation emitted from the two-dimensional grid at a plurality of points on the two-dimensional grid, the radiation detection device being mountable proximate the exhaust path and the two-dimensional grid and at least one computing device connected with the radiation detection device, the at least one computing device configured to generate a planar map of the temperature of the exhaust from the gas turbomachine based upon the intensity of the radiation emitted from two-dimensional grid detected at the plurality of points on the two-dimensional grid.Type: GrantFiled: September 3, 2013Date of Patent: November 1, 2016Assignee: General Electric CompanyInventors: Vivek Venugopal Badami, Daniel Francesco Driscoll, Scott Francis Johnson, Paul Joseph Martin, Nilesh Tralshawala, Guanghua Wang

Patent number: 9002530Abstract: A power plant control system determines an augmented operating parameter set point responsive to a life cycle cost (LCC) objective function responsive to a LCC model. The augmented operating parameter value may be responsive to an initial set point determined by a controls model and a performance indicator determined by a performance model. The power plant may include a thermal generator, such as a gas turbine or other fuel-burning generator, and the operating parameter may include firing temperature, fuel flow rate, steam pressure/temperature/flow rate, and/or another suitable operating parameter. An offer curve is generated responsive to the augmented operating parameter.Type: GrantFiled: April 23, 2012Date of Patent: April 7, 2015Assignee: General Electric CompanyInventors: Michael James O'Connor, Scott Francis Johnson, Mark Stewart Schroder
