Publication number: 20090217921Abstract: A solar energy collection system includes a primary solar receiver and a secondary solar receiver. The secondary solar receiver generates steam using energy from solar radiation incident thereon. The primary solar receiver receives the generated steam from the secondary solar receiver and superheats the steam using energy from solar radiation incident thereon. A plurality of heliostat-mounted mirrors reflects incident solar radiation onto one of the primary and secondary solar receivers. A controller aims a portion of the heliostat-mounted mirrors at the primary solar receiver such that a predetermined thermal profile is provided on a surface of the primary solar receiver.Type: ApplicationFiled: November 12, 2008Publication date: September 3, 2009Applicant: LUZ IL LTD.Inventors: Yoel GILON, Israel KROIZER

Publication number: 20080011290Abstract: The invention provides receivers which can be used to heat a working fluid to high temperature. In preferred embodiments, concentrated solar radiation is received and converted to heat at varying depths in the receiver such that multiple layers of surface are used to heat the working fluid. In addition, the depth-loading configuration helps to trap received heat to reduce radiant thermal loss.Type: ApplicationFiled: May 11, 2007Publication date: January 17, 2008Applicant: BrightSource Energy, Inc.Inventors: Arnold Goldman, Arieh Meitav, Ilia Yakupov, Israel Kroizer, Yuri Kokotov, Yoel Gilon

Patent number: 5970714Abstract: A geothermal power plant operating on high pressure geothermal fluid includes a primary separator for separating the geothermal fluid into two channels, one containing high pressure steam and the other containing high pressure liquid. A primary steam turbine in the high pressure steam channel is responsive to high pressure steam for generating electricity and producing heat depleted high pressure steam. A secondary separator separates the heat depleted high pressure steam into a steam component and a liquid component. A primary heat exchanger is responsive to the high pressure liquid and the steam component for transferring heat to said steam component thereby producing low pressure steam and cooled high pressure liquid.Type: GrantFiled: August 14, 1996Date of Patent: October 26, 1999Assignee: Ormat Industries Ltd.Inventors: Lucien Y. Bronicki, Nadav Amir, Yoel Gilon

Patent number: 5685154Abstract: An energy recovery, pressure reducing system for reducing high pressure gas in a transmission pipeline to a low pressure gas in a consumer pipeline includes an expander system having at least one expander for expanding the high pressure gas and producing work and low pressure gas that is supplied to the consumer pipeline, and a generator coupled to said expander for converting the work to electricity which is supplied to an electrical load. The system further includes apparatus including an on/off valve serially connected to a pressure regulating valve, the apparatus being connected in parallel with the expander system. The on/off valve has an open state for effecting transmission of gas through the pressure regulating valve which has an adjustable flow control opening for throttling high pressure gas and producing low pressure gas when the on/off valve is in its open state; and a closed state for preventing transmission of gas through the pressure regulating valve.Type: GrantFiled: October 2, 1995Date of Patent: November 11, 1997Assignee: Ormat Industries Ltd.Inventors: Lucien Y.

Patent number: 5671601Abstract: Power is produced from high presser geothermal fluid by separating the fluid into high pressure steam and high pressure brine, expanding the high pressure steam in a high pressure turbogenerator for producing power and heat depleted steam, and separating liquid from the heat depleted steam thereby producing dried heat depleted steam at a pressure and temperature lower than the pressure and temperature of the high pressure steam. The liquid so separated, and the high pressure brine are combined in a flash chamber which produces steam which is combined with the dried heat depleted steam and expanded in a lower pressure turbogenerator for producing additional power. Optionally, some of the high pressure steam is used to reheat the dried heat depleted steam and the steam produced by the flash chamber before such steam is expanded in the lower pressure turbogenerator.Type: GrantFiled: October 27, 1994Date of Patent: September 30, 1997Assignee: Ormat Industries, Ltd.Inventors: Lucien Y.

Patent number: 5632143Abstract: A gas turbine system with a heat recovery cycle includes a gas turbine unit that produces hot exhaust gases which are applied to a heat recovery heat exchanger containing a working fluid responsive to applied hot gases for producing vaporized working fluid and cooled gases which are vented. A turbine connected to a generator and responsive to the vaporized working fluid generates power and produces expanded working fluid. A condenser condenses the expanded vaporized working fluid to condensate which is returned to the heat recovery heat exchanger. A control device (94) controls the temperature of the applied hot gases, based on a sensed temperature (89) and include mixer apparatus (87) for mixing ambient air with the hot exhaust gases and producing a mixture of hot exhaust gases and ambient air before the mixture is applied to the heat recovery heat exchanger.Type: GrantFiled: June 20, 1994Date of Patent: May 27, 1997Assignee: Ormat Industries Ltd.Inventors: Uriyel Fisher, Joseph Sinai, Yoel Gilon
