Patent number: 10539339Abstract: The present disclosure is directed to a solar receiver having improved heliostat field control. The solar receiver includes a plurality of receiver panels arranged adjacent to one another. Each receiver panel includes a plurality of receiver tubes aligned tangentially to one another. Further, each of the plurality of receiver tubes includes an inlet and an outlet. In addition, at least one of the inlets or outlets of the plurality of receiver tubes are arranged at a center of the receiver panel along a height thereof.Type: GrantFiled: June 15, 2016Date of Patent: January 21, 2020Assignee: General Electric Technology GmbHInventors: Germain Felicien Augsburger, Apurba Kumar Das, Pedro Inigo, John David McGrane, Sunil Satyanarayana Murthy

Publication number: 20150136045Abstract: A heat exchanger apparatus for receiving water from a steam drum (1) and providing steam and heated unevaporated liquid water to the steam drum includes a first evaporator (EVAP-1) and a second evaporator (EVAP-2). The first evaporator can receive water from a steam drum via a first feed conduit (9) and the second evaporator can receive water from a second feed conduit (11). Both evaporators can output heated fluid to the steam drum via a combined evaporator output conduit (13). Each first evaporator passageway (14) only makes a single pass through a gas duct (15) having a heated gas flow (7) passing therethrough while each second evaporator passageways (24) can make one or more passes through the gas duct for transferring heat from the gas to the fluid within the evaporators. A portion of the first feed conduit can also have a pre-specified volume a pre-specified height below the first inlet (10).Type: ApplicationFiled: November 21, 2013Publication date: May 21, 2015Applicant: ALSTOM Technology LtdInventors: Suresh K. Shenoy, Jay Brian Anderson, Rahul J. Terdalkar, Donald William Bairley

Publication number: 20080053382Abstract: An upper bundle cleaning system of steam generator is disclosed which can clean heat transfer tubes and a plurality of tube support plates that support the heat transfer tubes and have slots, using a cleaning device transferred along a guide rail installed to an upper hand hole of the steam generator. The cleaning device is installed to an ascending/descending means which is vertically transferable. The cleaning device includes a frame, at least one or more guide means, a spray means, and a hinge unit, such that the cleaning device is ascended and descended by the ascending/descending means to clean the heat transfer tubes and the tube support plates.Type: ApplicationFiled: November 1, 2006Publication date: March 6, 2008Applicant: KOREA PLANT SERVICE & ENGINEERING CO., LTD.Inventor: Kyung-sub KIM

Patent number: 7013843Abstract: A downdraft boiler has a ceramic burner plate overlying a horizontal-tube heat exchanger at least the upper tubes of which each have an internal turbulator preventing premature vaporization of the water traversing the heat exchanger. The turbulator can consist of a twisted metal strip whose edges lie along helices.Type: GrantFiled: February 28, 2005Date of Patent: March 21, 2006Assignee: Slant/Fin CorporationInventors: George Weintraub, Donald Brown

Publication number: 20020043220Abstract: Inner peripheral grooves for transporting a liquid of a working fluid in the longitudinal direction of a first wick are provided along the first wick which transports the liquid contained in the evaporator to a heating portion in the evaporator by capillary force, and a liquid supply portion for supplying the liquid of the working fluid is further provided to the inner peripheral grooves. Therefore, the liquid of the working fluid can be efficiently supplied to the inner peripheral surface of the first wick with a simple structure, so that a loop type heat pipe which can be constantly stably operated can be obtained.Type: ApplicationFiled: February 5, 2001Publication date: April 18, 2002Inventors: Akira Yao, Hiroaki Ishikawa, Tetsurou Ogushi, Eiichi Ozaki

Patent number: 4232634Abstract: Apparatus and method for high efficiency transfer of heat from a combustion process to a working fluid wherein the combustion flame directly impinges upon a special material in contact with conduit means for directing the flow of the working fluid. The hottest part of the flame may be adjusted to directly contact such material. The apparatus in which such process takes place is subjected to a pressure gradient, directed from the top to the bottom of said apparatus such that the combustion gases are downwardly directed through the device for secondary heating of said working fluid prior to exhaust therefrom.Type: GrantFiled: October 16, 1978Date of Patent: November 11, 1980Assignee: Conservation Technologies, Inc.Inventors: George C.
