Patent number: 9377218Abstract: The invention relates to a solar receiver with natural circulation for generating saturated steam, which uses water/steam as a heat-transfer fluid and includes a combined circuit for fluid recirculation (forced circulation and natural circulation). The system comprises: water-walls which receive the radiation on the surface thereof and inside which the working fluid changes phase; riser pipes through which the water/steam mix exiting the pipes of the receiver rises towards the drum; downpipes through which the recirculation water descends from the drum to the receiver; and a support pump in order to increase the incident power in the receiver and start up the plant when necessary.Type: GrantFiled: March 31, 2010Date of Patent: June 28, 2016Assignee: Abengoa Solar New Technologies, S.A.Inventors: Raúl Navio Gilaberte, Lucía Serrano Gallar, Rafael Osuna Gonzalez-Aguilar, Paula Llorente Folch, Valerio Fernandez Quero

Patent number: 9182149Abstract: Molten salt solar receiver and procedure to reduce the temperature gradient in said receiver. The receiver consists of at least one panel of semi cylindrical geometry, formed by a combination of vertical pipes. The receiver (10) is supplied with a heat transfer fluid made up of molten salts which originate from a recirculation system which is composed of a mixture deposit (6), a hot salt storage tank (9) and a cold salt storage tank (8); the mixture tank (6) which is supplied by a part of the hot heat transfer fluid (4) which exits the receiver (10) and the cold heat transfer fluid (5) which exits the cold salt storage tank (8); the hot salt storage tank is connected to the exit of the receiver (10) so that a part of the heat transfer fluid which does not recirculate is stored (3).Type: GrantFiled: January 14, 2011Date of Patent: November 10, 2015Assignee: Abengoa Solar New Technologies, S.A.Inventors: Raúl Navío Gilaberte, Paula Llorente Folch, María del Carmen Romero Delgado

Patent number: 9151518Abstract: Solar concentrator plant using natural-draught tower technology, in which the tower is, in turn, used as cooling system. The tower houses saturated or superheated steam receivers in cavities with different orientations, with adaptive dynamic control of the heliostat field in order to direct said receivers towards different focusing points, for the production of electricity, process heat or solar fuels or for use in thermochemical processes.Type: GrantFiled: June 2, 2010Date of Patent: October 6, 2015Assignee: Abengoa Solar New Technologies, S.A.Inventors: Rafael Olavarría Rodríguez-Arango, Elena Garcia Ramírez, José Barragan Jiménez, Raúl Navio Gilaberte, Lucía Serrano Gallar

Patent number: 9151278Abstract: An economizer in a solar tower plant and operating method of said plant the purpose whereof is to make use of the heat from the heat losses generated around the solar tower receivers (3) to preheat the fluid with which the saturated steam or superheated steam solar receivers are fed. When the heat from the losses absorbed by the economizer (2) is not sufficient to achieve the necessary minimum temperature, a secondary economizer (4) is used which takes live steam (prior to it entering the turbine) and increases the temperature of the feed water of the receiver (3).Type: GrantFiled: March 15, 2011Date of Patent: October 6, 2015Assignee: Abengoa Solar New Technologies, S.A.Inventors: Raul Navio Gilaberte, Jose Maria Mendez Marcos, Javier Dominguez Rodriguez, Lucia Serrano Gallar

Patent number: 8978640Abstract: Superheated steam tower receiver with a well-defined configuration that benefits the transfer of heat between the surface of the component and the working fluid. Composed of at least four subpanels that define the circulation circuit for the steam by means of internal passages. The component is provided with saturated steam and for the production of said steam it is possible to use other solar concentrator technology. The proposed configuration minimizes the technological risks inherent in superheated steam receiver technology where drawbacks arise in the structure of the material owing to the thermal cycles to which the solar component is subjected.Type: GrantFiled: June 2, 2010Date of Patent: March 17, 2015Assignee: Abengoa Solar New Technologies, S.A.Inventors: Raúl Navio Gilaberte, Noelia Martinez Sanz, José Barragan Jiménez, Lucía Serrano Gallar, Paula Llorente Folch, José María Méndez Marcos

Publication number: 20150020793Abstract: The invention relates to a panel-based solar receiver for a thermal solar tower power plant (4), which comprises: a front panel (8), the external surface of which receives solar radiation (2) from the field of heliostats (3), a back panel (9), sealing elements (10) between the panels (8, 9), arranged at the lateral ends of both, an intake collector (5), located in the upper part of the panels (8, 9), where the heat transfer fluid enters the receiver (1) and an evacuation collector (6), located in the lower part of the panels (8, 9), where the heat transfer fluid leaves the receiver (1); wherein the front panel (8), back panel (9) and the two sealing elements (10) form the receiver body (16), which constitutes a passage for the heat transfer fluid (7) to travel through. Each solar tower can contain one or several panel-based receivers (1) and be arranged in series or in parallel, with the same or a different fluid (7) circulating there through.Type: ApplicationFiled: February 27, 2013Publication date: January 22, 2015Applicants: ABENGOA SOLAR NEW TECHNOLOGIES, S.A., INGENIERIA Y DISEÑO EUROPEO, S.A.
