Abstract: Method of operating a solar thermoelectric power plant that allows operation of high-, medium- and low-pressure superheating turbines with both superheated steam and saturated steam. The plant includes energy storage in high-pressure liquid tanks. The method described allows the direct introduction of saturated steam into a superheated steam turbine. This steam may receive an intermediate reheating between the high-pressure turbine and the low- and medium-pressure turbines to achieve conditions of superheated steam. The mode of operation proposed in the invention facilitates the operation of the plant in periods without sunshine (during transient periods, such as passing clouds or night time) or during discharge of accumulators (saturated liquid tanks at high-pressure).

Abstract: The invention relates to a configuration of the receivers in concentrated solar plants with towers comprising at least one medium-temperature receiver (3) and one high-temperature receiver (4) in which each high-temperature receiver (4) is located above and slightly in front of each medium-temperature receiver (3), such that a portion of the rays that bounce off the medium-temperature receiver (3) heats the rear portion of the high-temperature receiver (4) and in which the high-temperature receiver (4) is positioned such that the majority of the surface thereof is opposite the wall of the cavity (2), only the bottom portion of the receiver (4) remaining free.
