SOLAR PLANT WITH CONCENTRATOR (ALTERNATIVES)

FIELD: solar engineering. ^ SUBSTANCE: proposed solar plant with concentrator has cylindrical mirror reflectors and focal-region radiation detector. Concentrator is built of n (n >= 3) axially symmetrical cylindrical annular toroidal facet reflectors forming toroidal surface within space and n-side regular polyhedron on concentrator midsection pane. Cross-sectional area radius of cylindrical reflector equals distance between cross-sectional area center and symmetry axis and is four-times smaller than diameter of circle inscribed in polyhedron. Detector is made in the form of polyhedron with number of sides m >= 3 and is installed axially symmetrically in concentrator midsection plane, diameter of its circle circumscribed about detector being equal to radius of circle circumscribed about concentrator polyhedron. Four more alternatives of solar plant distinguished by shape of concentrator and radiation detector are also given in invention specification. ^ EFFECT: enhanced concentration of radiation on detector, duty factor and plant useful area utilization factor; enlarged aperture angle of concentrator. ^ 17 cl, 3 dwg
