  • Abstract
    We have developed a new dc plasma torch which is operated with a mixture of carbon dioxide and hydrocarbons, e.g., methane. Erosion of the graphite cathode is continually compensated by the deposition of carbon ions. The torch is typically operated at low currents and, due to the nature of the gases, high voltage. Thermal efficiency of the torch is around 75%.
