A solar central receiver includes a radiation receiver comprising a housing having an open aperture in one wall. An atmospheric airstream having a preselected concentration of particles is directed through the receiver and heated by focused solar radiation entering through the aperture. The particles are heated and, in turn, heat the airstream to a high temperature, typically 700 DEG C. and above. A compressed airstream is then heated by the heated airstream in a suitable heat exchanger. The heated compressed airstream may be used for any purpose, typically for driving a turbine and generator set. The turbine also drives a compressor which supplies the initial compressed air. Usually, the turbine exhaust is used as the inlet airstream to the radiation receiver. An auxiliary airstream and, optionally, an air curtain may be used to buffer and protect the particle-laden airstream from disturbance from the ambient, typically from high winds.
