Abstract: A particle receiver includes an inlet, an outlet and multiple tubes rotatably coupled to the inlet and the outlet. The tubes receive particles via the inlet, the particles passing along a passageway of each of the tubes to the outlet. The tubes receive a solar flux as they rotate to heat the particles passing through the tubes. A heat transfer coefficient of the particles is increased by increased mixing via air flowing in the tubes, fins used to mix the particles or via channels via which the particles pass through that increase turnover and mixing of the particles.

Abstract: A molten salt central receiver arrangement for transferring heat from panels to a molten salt that flows through the panels. A control device allows to change the condition of at least one of the panel arrangements of the molten salt central receiver arrangement depending on at least an operating parameter of at least one panel and/or depending on an environment signal that characterizes the actual or forecast available heat for the heat transfer to the molten salt. In normal operation passes, each having one or more panels, are connected in series such that molten salt flows in a serpentine or alternating way upward and downward through subsequent passes. In a parallel flow condition, molten salt may flow upward through all of the panels in parallel. In a drain condition, the molten salt is forced out of one or more panels and replaced by compressed air.

Abstract: 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.

Abstract: A solar receiver configuration (receiver) adapted to include a plurality of receiver heat transfer passes. Each pass includes a plurality of panels. Further, each panel includes a plurality of tubes, tangentially arranged, vertically extending between horizontally placed lower and upper headers. The headers, which are pipe assemblies with closed ends, of adjacent panels are horizontally and vertically offset one to another to form a substantially continuous tube surface. Such continuous tube surface enables solar heating of the fluid flow therefrom in at least a parallel flow arrangement and a serpentine flow arrangement.
