Abstract

Installation for generating superheated steam from raw water containing salt using preheaters for heating the raw water. The last preheater, as seen in the flow direction of the raw water, is followed via a control valve by a decompression cylinder. Part of the raw water evaporates and the vapor is withdrawn from the dome of the decomposition cylinder by a compressor which compresses and heats it and discharges it as superheated steam.
