Abstract

Solar power plant, including a tower, a solar heater disposed on the tower, a plurality of reflectors disposed in a given area for irradiating the solar heater, a water-steam circuit connected to the solar heater for conducting working medium thereto, a steam turbine connected in the water-steam circuit, a preheater for the working medium in the form of additional sunlight collectors being disposed outside of the given area and being connected to the water-steam circuit upstream of the solar heater, and means for adjusting the pressure in the water-steam circuit to cause the pressure of the steam in the solar heater to approximate the atmospheric air pressure outside.
