ABSTRACT:
A glass melting furnace which uses Joule effect heating between electrodes, has a parallel attachment of electrodes to a single power source. The electrodes are arranged in rows of four electrodes across the width of the furnace. Multiple rows of electrodes spaced along the length of the furnace are used. The electrodes within a row are connected in a parallel format such that the current flow within a row can only be between two electrodes which are adjacent to each other. A current limiting controller and thermal currents within the molten glass balancing the temperature within the molten glass.
