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.

Molten salt central receiver arrangement and operating method

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.

Solar receiver having improved heliostat field performance

A solar receiver, designed to use a heat transfer medium, includes a plurality of panels. Each panel is arranged and configured to enable the heat transfer medium to flow in at least one flow direction, one flow direction defining a pass, to obtain unique mass flux in each pass to optimize the heat flux capability of the pass while minimizing pressure drop across the selected passes of the heat transfer surface. A method thereof is also provided.

Solar receiver

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.

Solar receiver configuration

A solar thermal power system includes a solar receiver for heating thermal energy storage fluid to be stored and utilized from a thermal energy storage arrangement having hot and cold storage tanks. The system includes a steam generator arrangement, which utilizes the heat of the thermal energy storage fluid to produce steam to run a turbine. The arrangement includes a bypass line configured to bypass the hot storage tank from the steam generator arrangement, and to supply the hot thermal energy storage fluid from the solar receiver directly to the steam generator arrangement, during day times, when the solar receiver the steam generator arrangement are both in operating mode, thereby recovering stored potential energy available in the down corner hot thermal energy storage fluid from the solar receiver.
