METHOD AND APPARATUS FOR TREATING WASTE

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for treating waste.

SOLUTION: Waste is converted in a plasma-joule heated melter system (21) utilizing one or more arc plasma electrodes (27) and a plurality of joule heating electrodes (24). The arc plasma electrode(s) (27) can be configured for operation utilizing the AC or DC power, or for switching between AC and DC power. The arc plasma electrode(s) (27) can also be configured for independent arc voltage and arc current control. Joule heating circuits are configured for simultaneous operation with arcing electrodes, but without detrimental interaction with the arcing electrodes. The system of this invention provides stable, non-leachable products and a gaseous fuel. The gaseous fuel can be utilized in a combustion or non-combustion process to generate electricity.
