Abstract

Multiple arc discharges enable more than one arc to be operated in close proximity supplied from the same supply. This enables reduced individual electrode current to be used. Multiple electrodes may be used in d.c. arc furnaces and d.c. plasma furnaces for melting, liquid-phase smelting and particulate phase processes. Non-consumable multiple electrodes may be used to replace graphite electrodes in arc furnaces. Other applications include high temperature gas heating and in flight plasma reactions.
