Apparatus and method for generating superheated steam by means of solar thermal reheater and use of the superheated steam

摘要

The invention relates to a device for generating superheated steam using solar energy. The device has the following features: at least one heat transfer medium circuit with a heat transfer medium to absorb the solar energy in the form of heat and at least one water / water vapor circuit with water and / or water vapor to form the overheated water vapor. The water and / or water vapor can flow in one direction of flow in the water / steam cycle. The heat transfer medium circuit and the water / steam circuit are thermally coupled to one another to generate the superheated steam via at least one heat exchanger of at least one reheater. At least one water separator for separating water and water vapor from one another is arranged in the water / steam circuit in the flow direction upstream of the heat exchanger, so that essentially only water vapor can get into the heat exchanger. The one of the heat exchanger and the water separator are arranged in a common reheater pressure vessel.
