AN ELECTRIC MELTING FURNACE FOR GLASSIFYING HIGH-RADIOACTIVE WASTE

摘要

An electric melting furnace for glassifying high-radioactive waste characterized in that, in a furnace for melting glass containing platinum-group elements which has an outlet of glass at the bottom part of a melting tank, the bottom of the furnace surrounding the outlet has an inclination of more than 30 DEG and not more than 70 DEG with respect to the horizontal plane toward the cullet, and the distance l1 between a surface-inside opening part of the outlet and bottom ends of at least a pair of electrodes (3a, 3b) for supplying most of power required for glass melting is a half or more, but not exceeding, of the distance (l2) between the electrodes (3a, 3b).
