FIELD: solar power engineering.
SUBSTANCE: invention can be used in solar power plants of special application in which only ultraviolet part of solar radiation is used for water disinfecting and other plants of similar application. Control element and flat reflectors are installed on carrying structure after concentrator. Control element is installed along axis of parabola forming concentrator after its directrix at a distance of Δ from directrix, and flat reflectors are installed in path of rays reflected from reflecting faces of rectangular prisms so that normals to centers of all reflectors lie on one straight line perpendicular to axis of parabola at a distance of Δ/2 from its vertex. Reflecting coating of flat facets of concentrator is multilayer interference one, reflecting in ultraviolet zone of spectrum, and receiver of concentrated radiation is made up of set of parallel quartz glass tubes. Total configuration of receiver corresponds to shape of each facet.
EFFECT: improved control of aiming and simplified visual adjusting of solar power plant.
