METHOD OF REMOVING HEAT FROM CHAMBER CONTAINING MOLTEN SALT BATH

摘要

A method is disclosed by which heat may be extracted from an electrolysis chamber containing a molten salt bath. The method includes providing the chamber with a portion having a surface bordering directly on a gas space above the molten salt bath. Constituents from the bath are spewed and/or evaporated into this gas space. The mentioned portion is cooled so that the temperature of the surface bordering on the gas space is at least 200 DEG C below the bath temperature and above the freezing point of the mentioned constituents. This allows the constituents to deposit on the mentioned portion in liquid form, and drop back into the bath.
