Method and device for intermediate superheating in solar direct evaporation in a solar-thermal power plant

摘要

A solar-thermal power plant is provided. The solar-thermal power plant includes a working fluid circuit, a solar steam generator based on direct evaporation and a steam turbine for relieving the working fluid on a relief path while the working fluid supplies technical work. The solar-thermal power plant also includes at least one intermediate superheater, which can be heated using the working fluid. The working fluid may be removed from the circuit upstream of the intermediate superheater and superheated using the working fluid thereof, which can be fed downstream of the heating removal using the relief path. A method for operating a solar-thermal power plant is also provided.
