  • Patent number: 6152050
    Abstract: A compact furnace having three main chambers. In the first chamber, the water and the organic compounds are dissociated and vaporized and the metals and ceramics are vitrified and transformed into molten slag. A plasma torch or an induction coil can be used to provide the energy required for this operation. In the second chamber, the dissociated and vaporized compounds are burned in air or oxygen using a plasma torch to supplement the energy requirements. The third chamber receives and stores the vitrified slag. The furnace has a lightweight, multi-layered, air-cooled chamber wall construction that incorporates layers of advanced materials to provide both structural integrity at elevated operating temperatures and includes a dynamic cooling control element.

  • Patent number: 5877394
    Abstract: A centrifugal plasma arc furnace is used to vitrify contaminated soils and other waste materials. An assessment of the characteristics of the waste is performed prior to introducing the waste into the furnace. Based on the assessment, a predetermined amount of iron is added to each batch of waste. The waste is melted in an oxidizing atmosphere into a slag. The added iron is oxidized into Fe.sub.3 O.sub.4. Time of exposure to oxygen is controlled so that the iron does not oxidize into Fe.sub.2 O.sub.3. Slag in the furnace remains relatively non-viscous and consequently it pours out of the furnace readily. Cooled and solidified slag produced by the furnace is very resistant to groundwater leaching. The slag can be safely buried in the earth without fear of contaminating groundwater.
