TWO-STAGE SOLAR CONCENTRATING SYSTEM

摘要

An improved solar concentrating system uses a two sheet mirror construction wherein the rays of the sun are reflected and concentrated to a point focus. The sol ar concentrator may be used to increase the temperature of a substance such as metal, for use in a variety of applications including the melting of metals in a foundry furnace. The solar concentrating system comprises at least two single-curved parabolic mirrors. The rays of t he sun are reflected from a first single-curved parabolic mirror to a second single- curved parabolic mirror. The plane of symmetry of the second single-curved parabolic mirror is arrang ed substantially orthogonal to the plane of symmetry of the first single-curved parabolic mirror thereby concentrating the rays of the sun to a point focus.
