Abstract

1281424 Supply systems for glass melting furnaces H L PENBERTHY 8 June 1970 27659/70 Heading H2H [Also in Division H5] Protection of the electrodes 18, 20 in a glass melting furnace 10 is ensured by arranging by means of a differential impedance device that the alternating current applied to the electrodes from a source 22 has a direct current component superimposed thereon. The direct current component is derived from the A.C. supply 22 by a thyristor 28 connected in anti parallel with a diode 26 thus modifying a half cycle of the source relative to the preceding half cycle. Alternatively the diode 26 may be in parallel with a variable impedance device or a resistor which may be constituted by the resistance of the leads 37, 38. Three phase arrangements are disclosed wherein the electrodes are connected to the three phases and in which an auxiliary electrode connected to the neutral of the A.C. supply may be provided. In other embodiments the electrodes may be associated with an adjacent auxiliary electrode.
