    THERMOSOLAR PLANT OF THERMOSOLAR CONCENTRATORS DIRECT HEAT SUPPLIES AND OPERATION PROCEDURE
    SUCH THERMOSOLAR PLANT
    TECHNICAL FIELD OF THE INVENTION
    The present invention pertains to the technical field of the conversion of thermo-solar energy to electrical energy via mechanical energy by means of thermal machines capable of harnessing concentrated solar heat from disk-parabolic concentrators or heliostat field.
    OBJECTIVE OF THE INVENTION
    The present invention called "THERMOSOLAR PLANT OF DIRECT HEAT SUPPLY THERMOSOLAR CONCENTRATORS AND OPERATING PROCEDURE OF SUCH THERMOSOLAR PLANT", aims at the efficient conversion of thermosolar energy to electrical energy via mechanical energy by means of double-acting thermal mechanical actuator cylinders that operate under an unconventional thermal cycle of high thermal efficiency, where the said thermal machine consists of a double-acting thermo-mechanical actuator cylinder that performs work both by absorption and by heat rejection.
    BACKGROUND OF THE INVENTION
    The known solar-disk-parabolic type plants capture the heat concentrated in the focus of the parabola by means of a cavity within which there is an absorber traditionally composed of a heat absorbing filler based on metal mesh of high thermal absorption capacity material or ceramic foam, where the heat concentrated in the absorber is applied to a Stirling engine to generate electrical energy.
    Another option is the use of a field of heliostats that concentrate solar heat in a cavity within which the composite heat absorber is located
    by a filler based on stainless steel wire or ceramic foam, where the captured heat is applied to a Rankine cycle or a Brayton cycle A variant of these implementation options is patented with the national patent application number 201230077 characterized by a receiving cavity 5 equipped with a lens that increases the concentration of heat and operates at a pressure, which is that of the working fluid of the Rankine or Brayton cycle.
    In the invention called THERMOSOLAR PLANT OF THERMOSOLAR CONCENTRATORS DIRECT HEAT SUPPLIES AND OPERATION PROCEDURE OF SUCH THERMOSOLAR PLANT, several systems of 10 concentration of solar thermal energy are chosen, where the heat concentrated by each parabolic disk concentrator for medium or low temperatures, or a field of heliostats for high temperatures, is captured by the concentrated solar thermal energy sensor module located at the focal point of each concentrator system, where each heat sensor module is divided into several cavities filled with a heat absorbing material such as a metal mesh of a high thermal capacity material, ceramic foam or a gaseous working thermal fluid and dark tinting with high thermal capacity, and where the heat captured by the absorber is directly applied by means of a gaseous working thermal fluid to the actuator cylinder double acting following a thermal cycle High efficiency mico formed by a combination of open and closed processes.
    In the current state of technology there are no known solar thermal plants of this type.
    BRIEF DESCRIPTION OF THE INVENTION
    The invention called THERMOSOLAR PLANT OF THERMOSOLAR CONCENTRATORS DIRECT HEAT SUPPLIES AND OPERATION PROCEDURE OF SUCH THERMOSOLAR PLANT, is constituted by a double acting actuator cylinder for each concentration focus, which receives the concentrated solar heat directly from a field of heliostats or a disk parabola, which is absorbed by the thermal working fluid that feeds the double acting thermo-actuator cylinder. By having two solar thermal energy concentration systems (field of heliostats or disk parabolas), the heat concentrated by each parabolic disk concentrator for medium or low temperatures, or a heliostat field for high temperatures, is captured by the sensor module of 35 concentrated solar thermal energy located at the focal point of each system
