METHOD OF ELECTRIC HEATING-UP HEATING ELECTRODES' SYSTEM FEEDING WITH GAS-HEATED GLASS MELTING FURNACES

In this method of heating different out-of-phase voltage is supplied to each of at least three heating electrodes. This results in mutually different potential on the separate electrodes, which enables a balanced distribution of energy among all the heating electrodes. The danger of local corrosion...

Zusammenfassung:In this method of heating different out-of-phase voltage is supplied to each of at least three heating electrodes. This results in mutually different potential on the separate electrodes, which enables a balanced distribution of energy among all the heating electrodes. The danger of local corrosion of the superstructure of the melting furnace is reduced.
