FURNACE FOR MELTING INORGANIC SALTS

摘要

The invention relates to a furnace for melting inorganic salts, provided with a container (1), at least one inlet area (2) for solid inorganic salts, at least one outlet area (3) for molten inorganic salts, and at least one heat exchanger tube (5) or coil. Each heat exchanger tube (5) comprises: an inlet segment (5a) connected to the outer side wall of the container (1); a spiral segment (5b) which extends substantially along the length of the inner side walls of the container (1) and defines an inner space (6), said spiral segment (5b) being disposed on a substantially horizontal plane; and a substantially vertical outlet segment (5c) that extends downwards or upwards towards the base or the upper part of the container (1). Said furnace provides improved safety and performance over hitherto known furnaces.
