ABSTRACT:
The present invention provides a relatively compact and highly robust waste-to-energy conversion system and apparatus which has the advantage of complete or substantially complete conversion of a wide range of waste streams into useful gas and a stable, nonleachable solid product at a single location with greatly reduced air pollution to meet air quality standards. The gas may be utilized in a combustion process to generate electricity and the solid product can be suitable for various commercial applications. Alternatively, the solid product stream, which is a safe, stable material, may be disposed of without special considerations as hazardous material. In one embodiment of the invention, the conversion system includes an arc plasma furnace directly coupled to a joule heated melter. In an alternative and preferred embodiment of the invention, the arc plasma furnace and joule heated melter are formed as a completely integrated unit having circuit arrangements for the simultaneous operation of both the arc plasma and the joule heated portions of the unit without interference with one another. The apparatus may additionally be employed without further use of the gases generated by the conversion process.
