Summary

Use of longitudinal current conduction between parallel submerged transverse electrodes and arrangement of zone border electrodes to conduct in both adjoining zones minimize the number of electrodes. Heating is controlled to maintain constant average glass conductance between the electrode pair in the exit half of each zone. Muffled cooling has also been developed as a general gas or electric heat performance improvement.
