Solar radiation receiver, solar thermal power plant and method for operating a solar thermal power plant

摘要

In a solar radiation receiver (1) for solar thermal power plants (100) in particular for operation with a molten salt as heat transfer medium with a reflector device (3) and with an absorber tube (5) with an absorber tube wall (5a), wherein the absorber tube (5) has a tube space (7 ), through which the heat transfer medium is conductive forms, which is enclosed by an inner surface (5b) of Absorberrohrwandung (5a), it is provided that in the tube space (7) a heat conducting device (9) is arranged, extending from the inner surface (5b) of a region of the absorber tube wall (5a) facing the reflector (3) during operation extends to a region of the absorber tube wall (5a) facing away from the reflector (3).
