The heated molten salt is sent to a set of hot storage tanks. The heated molten salt is then pumped to a steam generation system to produce steam for process and/or power generation. Lower salt temperatures are useful in processes that use lower steam temperatures, such as thermal desalination. Lower salt temperatures and low chloride molten salt reduce the corrosion potential, permitting the use of lower cost alloys for the solar receivers, hot storage tanks, salt pumps, piping and instrumentation and steam generation system. Multiple sets of modular, shop assembled storage tanks are also used to reduce the amount of salt piping, simplify draining, and reduce field assembly and plant cost. | 04-07-2016 |
20160115945 | SOLAR THERMAL ENERGY STORAGE SYSTEM - Disclosed is a thermal energy storage system for storing collected solar thermal energy. The system comprises a solar thermal energy collection facility in the form of a field of parabolic troughs, which is in thermal communication with a molten salt circuit. The molten salt circuit is in fluid communication with a molten salt storage facility comprising at least three storage tanks that are each in fluid communication with the molten salt circuit. The multiple tanks set-up allows using cheaper materials, and a more efficient storage of thermal energy. | 04-28-2016 |
20160164450 | SOLAR GENERATION SYSTEMS HAVING A COMMON RECEIVER BRIDGE AND COLLECTORS WITH MULTIPLE MOBILE WEBS - The invention relates to a system for concentrating radiation in order to broaden the scale and efficiency of solar generation technologies that consist in a field of vast reflecting surfaces, in the form of collector webs, which concentrate the radiation in a common receiver bridge, which can use a thermal, photovoltaic or thermomechanical Stirling engine receiving mechanism. The collector webs hang from a structure of very tall portals and consist of mirrors adhered to a bundle of cables, forming a surface with variable topology, which can vary the shape and position thereof by stretching and tilting the support structure thereof, which can rotate to track the position of the sun. In addition, the invention provides a receiver which is installed on a bridge that runs longitudinally at height over the solar field. Each receiving mechanism offers the alternative of mobile modular receiving units such as funiculars or a stationary system adhered to the bridge in longitudinal series. The structure of the bridge supports a service access, a longitudinal area for installing thermal fluid matrix pipes and a power discharge network in accordance with the receiving mechanism installed. | 06-09-2016 |
