FIELD: solar radiation engineering.;SUBSTANCE: solar electro-thermal station has motionless spherical mirror concentrator, open-type energy generation air circuit, movable girder rotating around center of sphere and watching Sun's movement, preliminary, basic and water heat exchangers, compressor, turbine and electric generator. Preliminary heat exchanger has cylindrical profile; basic heat exchanger has profile specified by parametric equation. Basic heat exchanger is made of two parts connected in series: lower part, which has profile truncated from the top in correspondence with equation, and top part made in form of truncated cone. Both parts as Preliminary heat exchanger are made in form of longitudinal adjoining separate air ducts having cross-section in form of trapezoid. Preliminary heat exchanger is mounted in air duct between compressor (or regenerative heat exchanger, if any) and basic heat exchanger. Output of basic heat exchanger is connected to input of turbine. Regenerative heat exchanger is mounted at output of turbine. Water heat exchanger is mounted behind regenerative heat exchanger in output airflow coming from turbine. Compressor, regenerative heat exchanger, preliminary heat exchanger, basic heat exchanger, turbine, electric generator and heat exchanger are connected in small-sized energy generating un it disposed in lower and central parts of movable girder.;EFFECT: improved reliability of operation, increased efficiency.;4 dwg
