20110062707 | SEALED MECHANICAL CONNECTION BETWEEN GLASS AND METAL FOR RECEIVER TUBES USED IN SOLAR PLANTS - The invention relates to a sealed mechanical connection between glass and metal for receiver tubes used in solar plants of the type using a heat-transfer fluid, which uses a mechanical force in order to establish the seal between the inner metal tubes and the outer glass tubes, between which tubes a high vacuum is established in order to prevent heat losses. According to the invention, a flexible, deformable metal joint is used for the above-mentioned seal, which joint, when duly compressed, adapts to the corresponding surfaces of the tubes to be sealed, thereby establishing the seal between the respective tubes. In addition, the invention can include a continuous system for maintaining the necessary vacuum between both types of tubes. | 03-17-2011 |
20120096859 | AIR- AND STEAM-TECHNOLOGY COMBINED SOLAR PLANT - Air- and steam-technology combined solar plant for use in the fields of electricity production, process heat, and solar fuels, as well as thermo-chemical processes, produced from the combination of a non-pressurised-air solar receptor, a saturated-steam solar receptor and a heat exchanger separate from the solar input that is used to produce overheated steam. | 04-26-2012 |
20120125319 | SUPERHEATED STEAM SOLAR RECEIVER - 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. | 05-24-2012 |
20120299289 | NOVEL EXPANSION COMPENSATION DEVICE AND METHOD FOR MANUFACTURE THEREOF - New expansion compensating device and manufacturing method of the same, of those used in solar power absorber tubes featuring a dual bellows design where the height of the waves of the bellows is not regular, but the second wave is greater (where it supports more load) and diminishes towards the ends. With this design improving the performance of the receiver is achieved because it shortens the length of the device and consequently there is more surface area receiving solar radiation as well as it decreases the necessary diameter of glass tube and therefore its cost. | 11-29-2012 |

20130220308 | NOVEL ARRANGEMENT OF NON-EVAPORABLE GETTERS FOR A TUBE SOLAR COLLECTOR - The invention relates to a novel arrangement of non-evaporable getters for a tube solar collector, said tube collector being of the type that includes an outer glass tube ( | 08-29-2013 |
20130344238 | METHOD FOR IN SITU COATING A TOWER SOLAR RECEIVER - The invention relates to a method for in situ coating a tower solar receiver in order to protect the surface of the receiver from corrosion and to increase absorptivity of same, which is carried out in several steps: surface preparation, application of the coating, curing, optional vitrification, and controlled cooling. The surface preparation is done by zones depending on the size of the receiver, a methodology that enables an intercalated application of the coating in order to minimize the risk of corrosion. The curing stage is carried out by supplying steam to the inside of the receiver tubes, and temperature requirements above the operating limits of the boiler are adjusted with the solar field as support system. Vitrification is done using saturated steam traveling through the receiver tubes and concentrating solar radiation on the surface of the receiver from the solar field. | 12-26-2013 |
20140146305 | SPECTROPHOTOMETER FOR THE AUTOMATED OPTICAL CHARACTERIZATION OF SOLAR COLLECTOR TUBES AND METHOD FOR THE OPERATION THEREOF - The invention relates to a spectrophotometer for the automated optical characterization of solar collector tubes and to a method for the operation thereof, that measures the coefficient of transmission of the glass tube and of reflection of the metal tube. The device includes all the necessary components for taking said measurement, such as the optical bench supporting the tube, the standard or framework, and the optical modules for the device, a main module that generates the light bundles, a measuring module that measures the coefficient of transmission of the outer glass tube and the coefficient of reflection of the inner metal tube, a mechanical system of tube rotation, an electronic system of data acquisition and processing, an external computer for controlling the device and processing the data measured, and a system of communication between the device and the computer. | 05-29-2014 |
