A solid fuel skewer suspension burning system for a kiln, comprises a skewer rod and a solid fuel loading system. The skewer rod has a first end and a length that extends longitudinally. The solid fuel loading system includes a fuel centering and staging area that receives fuel from a conveyor system, and a fuel loading area that receives fuel from the fuel centering and staging area. The solid fuel is inserted upon the skewer rod at the fuel loading area. The solid fuel loading system also includes a first clamp, an airlock and a plow. The first clamp holds the skewer rod and defines a first position between the first clamp and a free end of the skewer rod. The airlock is spaced from the first clamp and has a first airlock gate and a second airlock gate. The plow reciprocates substantially longitudinally in cooperation with the skewer rod to advance fuel along at least a portion of the length of the skewer rod.

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.
