Solar heat collector for use in solar-thermal plant, has absorbers absorbing diffuse radiation reflected by mirror surface, where receiver tube is at higher temperature level, and absorbers are in lower temperature level
Solar heat collector for use in solar-thermal plant, has absorbers absorbing diffuse radiation reflected by mirror surface, where receiver tube is at higher temperature level, and absorbers are in lower temperature level
The collector has a parabolic profiled reflecting mirror surface, and a receiver tube arranged on a focus axis of the reflecting mirror surface, where a direct radiation irradiated on the reflecting mirror surface is reflected and concentrated in the receiver tube. Diffuse radiation reflected by the reflecting mirror surface is absorbed by a set of absorbers arranged laterally at edges of the mirror surface and perpendicular to a main mirror plane, where the receiver tube is at a higher temperature level, and the absorbers are in a lower temperature level.
