Abstract: A method and apparatus are disclosed for injecting vaporizable material, such as a vaporizable waste, into a molten bath. A gas is injected into the molten bath at a rate which is sufficient to cause the gas and the molten bath to form a gaseous dispersion. The gas component of the gaseous dispersion occupies a sufficient fraction of said dispersion to cause a significant portion of the vaporizable material, at a rate at which the vaporizable material is injected into the molten bath, to volatilize, combust or decompose during exposure to said gas component. A vaporizable material, such as a particulate solid or hazardous liquid waste, is injected into the gaseous dispersion at a rate which cases a significant portion of the vaporizable material to volatilize, combust or decompose during exposure of said vaporizable material to the gas component of said gaseous dispersion.

Abstract: A method and apparatus are disclosed for injecting liquids into a molten bath. The method includes forming a suitable liquid dispersion of a liquid phase disposed in a gas phase. The liquid phase has a ratio of surface area to volume which is sufficient to cause an accumulated amount of the liquid phase in the molten bath to be significantly less than that which would occur by injection of a continuous stream of the liquid into the molten bath. The liquid dispersion is directed into the molten metal bath, whereby the liquid volatilizes or decomposes. The rate at which the liquid dispersion is injected into the molten bath is sufficient to cause the liquid of the liquid phase to volatilize or decompose at a rate which is sufficient to cause the accumulation of the liquid phase in the bath to be significantly less than that which would occur by injection of a continuous stream of the liquid into the molten bath. The apparatus includes an atomizer which is disposed at a reactor containing the molten bath.
