Solar radiation receiver for solar irradiation of solid particles, an industrial plant with a solar radiation receiver, as well as a process for the solar irradiation of solid particles

摘要

Solar radiation receiver (1) for solar irradiation of solid particles, with an absorber device (3), in which the solid particles are heated by concentrated solar radiation, wherein the absorber device (3) a horizontal conveyor (7) with a horizontal or at an angle of maximum 10 ° the horizontal arranged conveying surface (11), wherein the conveying surface (11) is movable in at least one main conveying direction and the solid particles on the conveying surface (11) are transportable and wherein the concentrated solar radiation is directed to the conveying surface (11), characterized in that between the solid particles and the conveying surface (11) there is an average friction coefficient μ for the static friction and the conveying surface can be accelerated in repetitive sequences in the main conveying direction with an acceleration avor of maximum μ · acceleration g up to a predetermined speed and subsequently after a predetermined period of time with a delay of at least 1.5 · avor can be braked, wherein the conveying surface (11) by a plate (7) is formed and wherein the plate (9) is a ceramic plate or a steel plate and / or wherein the plate (9) on the conveying surface (11) forming side is coated with a ceramic layer, preferably an aluminum oxide layer.
