ABSTRACT:
A solar furnace electricity generating system is provided herein. It includes a concentrator and accumulator for the sun's rays to generate a concentrated high temperature solar beam. A heat hearth is disposed, e.g., in the ground, to absorb the concentrated high temperature solar beam. A plurality of concentric alternating heat-transfer-medium-containing chambers and heat absorption zones are provided around the heat hearth. These zones are the following: a primary chamber containing a first heat-transfer-medium in heat-transfer contact with the heat hearth; a primary heat-absorption zone containing a primary heat-absorbing material in heat-transfer contact with the primary chamber; a secondary chamber containing the same heat-transfer-medium in heat-transfer contact with the primary zone; a secondary heat-absorption zone containing a second and different heat-absorbing material in heat-transfer contact with the secondary chamber; and a tertiary chamber containing the same heat-transfer medium in heat-transfer contact with the secondary zone. Valved outlet lines are provided from each heat-transfer-medium-containing chamber to conduct such heat-transfer media to a common vapor outlet line leading to a vapor-powered electricity-generating turbine. An outlet line is provided from the liquid reservoir to a plurality of valved inlet lines, each leading to an associated heat-transfer-medium-containing chamber. Control means are provided to actuate selected vaporization/condensation cycles from selected heat-transfer-medium-containing chambers, generally from the outer zones first and then from the inner core zones, to the exclusion of similar vaporization/condensation cycles from other heat-transfer-medium-containing chambers. In this way, substantially continuous generation of electricity during periods of daylight and nighttime is provided.
