Abstract:
A solar thermal power plant comprises a solar radiation receiver mounted on a tower surrounded by a heliostat field to receive solar radiation reflected by heliostats. A power generation circuit includes a steam turbine for driving an electrical generator to produce electrical power, and water in the power generation circuit is heated directly by solar radiation reflected onto the solar radiation receiver by the heliostat field to generate steam to drive the steam turbine. An energy storage circuit includes a thermal energy storage fluid, such as molten salt, which is capable of being heated directly by solar radiation reflected by the heliostat field. A heat exchanger is also provided for recovering thermal energy from the thermal energy storage fluid. The recovered thermal energy may then be used to generate steam to drive the steam turbine.
Abstract:
A solar receiver having a radiation capturing element for capturing solar radiation passing through a radiation receiving aperture into a cavity formed by the radiation capturing element, the aperture having a first diameter and the cavity having cylindrical walls of a second diameter, the second diameter being larger than the first diameter, preferably about twice as large. Furthermore, the length of the cavity is greater than the first diameter, preferably about twice as great.
Abstract:
A solar power system, comprising a solar receiver that absorbs solar radiation, at least first and second fluid flow paths passing through the receiver, a first working fluid flowable through the first fluid flow path to absorb thermal energy from the receiver up to a first maximum temperature and a second working fluid flowable through the second fluid path to absorb thermal energy from the receiver up to a second maximum temperature.
Abstract:
A solar receiver, designed to use a heat transfer medium, includes a plurality of panels. Each panel is arranged and configured to enable the heat transfer medium to flow in at least one flow direction, one flow direction defining a pass, to obtain unique mass flux in each pass to optimize the heat flux capability of the pass while minimizing pressure drop across the selected passes of the heat transfer surface. A method thereof is also provided.
