Solar energy concentration equipment - has primary reflectors in groups each working with curved secondary reflector above tower

摘要

The solar energy concentration equipment comprises a tower (1) with a light vessel (4) and a radiator absorber (5) below it, also a large number of primary reflectors (6,7) mounted round the tower. These concentrate the rays striking them onto a secondary reflector (2) mounted above the vessel. The secondary reflector has a number of separate curved mirrors, while the primary reflectors are divided into groups, each working with one of these mirrors, so that the rays transmitted are projected into the top opening (9) of the vessel. The mirrors can be mounted on a bowl-shaped structure, convex towards the vessel, those nearest the outermost edge working with the outermost primary reflectors.
