Принадлежит: GLASSPOINT SOLAR, INC.

In a “once-through” configuration, feedwater is pressurized, preheated, and evaporated in a series of pipes exposed to concentrated solar energy to produce a water-steam mixture for direct distribution to an industrial process such as enhanced oil recovery or desalination. Active steam quality management, in a preheat mode, vents warm/hot water and low-quality steam to a return vessel where steam is recondensed via contact with water and fed back in as feedwater. In an operating mode, the venting is disabled, and high-quality steam is directed as an outlet stream. Inlet water flowrate and outlet valves are managed to reduce effects of variation in the solar energy. A steam generator continuous piping system uses a single continuous receiver pipe that is illuminated by segmented parabolic mirrors enabled to track the sun to reduce high-temperature fouling. Provisions for steam generator piping recurring maintenance are provided. Low-temperature “overnight” solar field management reduces low-temperature fouling. 1.

A torsion box is tiltably mounted to the support frame to provide a wide range of movement of the torsion box and the finish surface thereon, which is preferably of a single plane parabolic shape that carries a layer of highly reflective chrome material. A receiver is mounted above the surface of the chrome layer at the focus of the parabola by a bracket to optimize reflection of radiation thereto. Plumbing transports liquid, such as water, through the receiver for heating thereof for various purposes, such as water desalinization. Thus, the solar concentrator is an optimized low cost and easy to manufacture solar concentrator.

The present invention relates to an improved solar energy concentrating system. The system comprises a dual axis sun tracking paraboloid dish collector on a polar mount, with a re-reflecting mirror in top of the paraboloid dish, which reflects the concentrated solar irradiation into an opening in the paraboloid dish into a light pipe and with a movable third mirror redirects the light into a second light pipe along the polar axis, which with a fourth fixed mirror, sends the concentrated solar irradiation into a third light pipe to the cavity receiver.
