Abstract
Pairs of electrodes are symmetrically placed about the bend of a forehearth of a glass melting furnace. The electrodes are connected to the dual secondary windings of a step down transformer such that the firing paths of the electrodes cross each other in the molten material. The flow of the material across the firing paths coupled with the electrodes being connected to the dual secondaries of a common step-down transformer prevents hot spots and produces a balanced current flow across both firing paths.
