ABSTRACT OF THE DISCLOSURE A method and system are provided for feeding a slurry of energetic wastes, such as propellants or explosives, dissolved in a volatile solvent such as acetone, for introduction into a molten salt for destruction of such waste, without vaporization of the solvent in the feeding device or injector, and without deposition of explosive residue on the inside surface of such injector. This is achieved by introducing carbon dioxide liquid into the slurry feeding device or injector, and into heat exchange relation with the feed slurry to cool the slurry and prevent vaporization of the volatile solvent, and to thereby prevent deposition of explosive solid residue in the feed injector. The injector is mounted on the vessel which contains the molten salt and such vessel is positioned in a furnace for heating the molten salt to reaction temperature. Although the injector for feeding the propellant slurry is heated by the furnace, sufficient cooling is achieved by the liquid carbon dioxide within the injector to prevent vaporization of the volatile solvent.
