RECEIVER FOR A SOLAR THERMAL INSTALLATION AND SOLAR THERMAL INSTALLATION THAT INCLUDES SAID RECEIVER

摘要

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.
