| 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 |
