A working unit powered by at least one of the first generator and the second generator is provided to utilize the cooling effects from the cooling system.Type: ApplicationFiled: October 14, 2005Publication date: April 19, 2007Inventors: Patrick Zuili, Sean Hackner

Publication number: 20070084208Abstract: A generating facility is provided for generating electricity from both solar and non-solar energy sources. The solar generating portion of the facility includes capability to directly generate electricity from solar insolation, or to store the solar energy in a tangible medium, including stored heat, or solar generating fuel. The generating facility is configured to generate electricity simultaneously from both solar and non-solar sources, as well a solely from immediate solar insolation and from solar energy stored in a tangible medium. Additionally, the solar generating capacity may be segregated; such that separate spectra of solar insolation are used to capture heat for steam turbine based electrical generation, capture light energy for photovoltaic based electrical generation, and to grow biomass to generate a solar fuel.Type: ApplicationFiled: November 22, 2006Publication date: April 19, 2007Inventor: Arnold Goldman

Publication number: 20070084209Abstract: The combustor (5) of a gas turbine (7) is supplied with coal bed methane (51), oxygen (53) and a part of the flue gas (55), predominantly CO2, produced from the gas turbine (7) and sent through a heat recovery steam generator (27), all under pressure. The heat recovery steam generator (27) receives the hot flue gas and generates steam (57) for driving a steam turbine (29). The other part of the flue gas stream that passes through the heat recovery steam generator (27) is supplied to a suitable underground storage region (3).Type: ApplicationFiled: September 29, 2004Publication date: April 19, 2007Inventor: Nello Nigro

Publication number: 20070084211Abstract: One embodiment of the present application is a gas turbine engine with a compressor that includes a variable geometry mechanism to vary working fluid flow area. A desired state of this mechanism is selected different than a current state to change the amount of flow area. The mechanism has a hysteresis band corresponding to a difference between increasing the flow area to reach the desired state and decreasing the flow area to reach the desired state. To control operation of the mechanism within this hysteresis band, a determination is made whether the desired state corresponds to a greater flow area or a lesser flow area relative to the current state.Type: ApplicationFiled: October 18, 2005Publication date: April 19, 2007Inventors: Ray Bowman, Joseph Jaeger, Phillip Steffen, Robert Kiser

Publication number: 20070084212Abstract: In a method of operating a compressor of a gas turbine, where compressor air sucked in from the environment is cooled down by evaporation cooling before entering the compressor, before starting operation of the compressor, maximum possible temperature drops which could be achieved by evaporation cooling are determined dependent on different ambient conditions and/or are provided as a data set. These temperature drops are correlated with a compressor map containing maximum temperature distortions at different ambient conditions and different rotation frequencies of the compressor which have to be met in order to avoid pumping. The evaporation cooling is then only operated when current ambient condition result in a maximum possible temperature drop from which a predetermined fraction of between 50% and 100% does not exceed the maximum distortion which can be taken from the compressor map for these ambient conditions and the current rotation frequency of the compressor.Type: ApplicationFiled: November 22, 2006Publication date: April 19, 2007Inventors: Giovanni Cataldi, Christian Faehndrich, Charles Matz

Publication number: 20070084213Abstract: A combustor assembly includes a convergent segment followed by a divergent segment to advantageously improve combustion. The combustor assembly includes a first segment beginning at a forward end that transitions to a second segment past a transition segment in a direction along a combustor axis toward an aft end. The reduction in cross-sectional area within the first segment provides desirable fuel and air mixing properties. The convergent first segment in combination with the divergent second segment decreases residence time of fuel-air mixture within the combustor chamber that decreases production of undesirable emissions from the combustor assembly.Type: ApplicationFiled: October 17, 2005Publication date: April 19, 2007Inventors: Steven Burd, William Sowa, Albert Cheung, Stephen Kramer, Reid Smith, James Hoke
