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

摘要

Solar radiation receiver (1) for solar thermal power plants (100) for operation with a molten salt as a heat transfer medium with a reflector device (3) and an absorber tube (9), wherein a glass tube (17) at a distance from the absorber tube (9) is arranged, and wherein the Absorber tube (9) a tube space (11), through which the heat transfer medium is conductive forms, which is enclosed by an inner surface (9a) of the absorber tube (9), the tube space (11) is formed as a gap space with variable volume, characterized that on the inner surface (9a) of the absorber tube (9) heat conducting body (19) are arranged, which protrude into the tube space (11).
