ABSTRACT:
A feed system for feeding solid propellant or explosive energetic materials, e.g. in the form of chunks, into a molten salt furnace for destruction of said materials by oxidation with air, while substantially avoiding the danger of detonation of such materials during feeding. The system comprises a feed hopper separated from the molten salt furnace by a barrier such as a concrete wall. The feed hopper is preferably vibrated to move the chunks of waste to an inclined chute which passes through a penetration in the barrier to the furnace, the chute also being preferably vibrated to facilitate passage of the waste material. The chunks of waste are discharged from the inclined chute either directly into the molten salt bath in the furance, or added incrementally thereto by a lock valve arrangement.
