Abstract

PURPOSE:To improve a raw material fusion capacity by having an inclination of 30-70 deg. at which the circumferential furnace bottom of an outlet is against the outlet and setting the distance between the furnace opening part of an outlet and a pair of electrodes for power supply in a prescribed range. CONSTITUTION:Furnace bottom refractories 2 have an inclination of 30-70 deg., for example 45 deg., against a freeze valve 6. And the distance 1 between the bottom end of a pair of electrodes 3a, 3b and the furnace bottom for holding the temperature of melting glass at the suitable temperature for raw material fusion represents from one third to one half of the distance 12 between electrodes. In this case, when the injection into a canister is performed by the freeze valve 6 for removing platinum group elements, the platinum group elements are removed every injection. In the case of said electrode positioning, good temperature distribution is shown even if the platinum group elements exist, raw material fusion capacity can be improved and so large-sized electric fusion furnaces for high radioactive waste glass solidification can be realized.
