Abstract
A furnace contains a plurality of zones. Each zone has at least one electrode adjacent a separate electrode of an adjoining zone. The adjacent electrodes are connected to separate power supplies, specifically separate windings of a transformer. In this manner, zones can be arranged immediately adjacent each other while minimizing current paths between non-associated electrodes to substantially zero. It is therefore, unnecessary to otherwise widely space firing zones within a furnace, and the spacing within the furnace may be filled with closer adjacent firing zones.
