FIELD: heating. ^ SUBSTANCE: invention is related to the field of solar technology, in particular, to creation of solar stations with concentrators of solar radiation for generation of electricity and heat. In solar station with concentrator the latter is made in the form of axial-symmetric ring-shaped toroidal mirror reflector, which has cross section formed by two coupled differently sized quarters of circumferences with radius R and r (R>r>0), axes OO2 and O1O3 of toroidal reflector cross section are removed from symmetry axis at the distance a=r, diameter D of concentrator is equal to D=2(r+R), cylindrical receiver with base radius b=r and height h>=R-r is installed as axial-symmetric in plane of circumference centers with radius r, and geometric coefficient of concentration of station is equal to where k - geometric concentration coefficient; R - larger radius of reflector, equal to radius of larger quarter of circumference that forms station profile; r - smaller radius of reflector, equal to radius of smaller quarter of circumference that forms station profile. ^ EFFECT: increase of concentrator aperture angle and concentration of radiation in receiver of radiation. ^ 5 cl, 1 dwg
