    Abstract: A solar receiver having a higher yield than a central tower receiver. The receiver comprises a plurality of absorbent tubes for absorbing incident energy from light guides suitable for capturing solar radiation in solar collector concentration focal points, the absorbent tubes being arranged consecutively and in parallel, adjacently in relation to a direction transverse to the longitudinal axis of the absorbent tubes. The tubes contain a circulating heat-transfer fluid. The longitudinal axes are contained in at least two planes, defining at least two lines of absorbent tubes arranged in an alternating manner, and partially superimposed. The receiver also comprises containers subjected to a vacuum in order to enclose the absorbent tubes and reduce losses by convection.

  • Publication number: 20140230806
    Abstract: A collector system (12) is disclosed that comprises a row of linearly conjoined collector structures (13). The collector system is arranged to be located at a level above a field of reflectors (10) and to receive solar radiation reflected from the reflectors within the field. The collector structure (13) comprises an inverted trough (16) and, located within the trough, a plurality of longitudinally extending absorber tubes (30) that, in use, are arranged to carry a heat exchange fluid. The absorber tubes (30) are supported side-by-side within the trough and each absorber tube has a diameter that is small relative to the aperture of the trough. The ratio of the diameter of each absorber tube to the trough aperture dimension is of the order of 0.01:1.00 to 0.10:1:00 and, thus, a plurality of absorber tube functions, in the limit, effectively to simulate a flat plate absorber.
