APPARATUS AND METHOD FOR PRODUCING SUPERHEATED STEAM BY MEANS OF A SOLAR THERMALLY OPERATED REHEATER AND USE OF THE SUPERHEATED STEAM

摘要

The invention relates to an apparatus for producing superheated steam by means of solar energy. The apparatus has the following features: at least one heat-transfer medium circuit with a heat transfer medium for absorbing the solar energy in the form of heat and at least one water/steam circuit with water and/or steam for forming the superheated steam. In this arrangement, the water and/or the steam may flow in one direction of flow in the water/steam circuit. For producing the superheated steam, the heat-transfer medium circuit and the water/steam circuit are thermally coupled to each other by means of at least one heat exchanger of at least one reheater. In the water/steam circuit, at least one water separator is arranged upstream of the heat exchanger in the direction of flow for separating water and steam from each other, so that substantially only steam can enter the heat exchanger. The heat exchanger and the water separator are arranged in a common reheater pressure vessel.
