Abstract
The present invention relates to a sealed plasma melting furnace for treating low- and intermediate-level radioactive waste, which allows the secondary pollutants to be minimized. The sealed plasma melting furnace includes: a waste supply chamber communicatively provided with a hopper; a pyrolysis chamber channel communicatively coupled with the waste supply chamber; a pyrolysis chamber having a burner mounted thereon; a melting chamber channel guiding the waste transferred from the pyrolysis chamber communicatively provided therewith to fall down; a melting chamber provided with a furnace interior portion accommodating a molten substance on a bottom surface thereof; a processed molten substance discharge channel discharging the processed molten substance generated in the melting chamber; a secondary combustion chamber channel inducing and exhausting an off-gas flow generated in the melting chamber; and a secondary combustion chamber inducing complete combustion of the off-gas input from the secondary combustion chamber channel.
