Apparatus and method for producing superheated steam by means of a solar-thermally operated reheater and use of the superheated steam

An apparatus for producing superheated steam by solar energy, comprising:

• at least one heat-transfer circuit with a heat-transfer medium for taking up the solar energy in the form of heat,
• at least one water/steam circuit with water and/or steam for forming superheated steam, wherein:
• the water and/or the steam flow in one direction of flow in the water/steam circuit,
• the heat-transfer circuit and the water/steam circuit are coupled thermally to one another via at least one heat exchanger of at least one reheater for producing the superheated steam,
• at least one water separator for separation of water and steam from one another is disposed in the water/steam circuit in direction of flow upstream of the heat exchanger, so that essentially only steam is supplied to the heat exchanger, and
• the at least one heat exchanger and the at least one water separator are disposed in a common reheater pressurized container.
