Abstract
An at least partially electric glass furnace, includes a melting tank made of refractory materials that is suitable for containing a bath of molten vitrifiable materials and a plurality of electrodes for heating the bath, the electrodes being supplied with alternating electric current by an electric apparatus including at least one transformer suitable for generating a plurality of output groups in a phase with a phase difference between each output group, each output being connected to at least one of said electrodes by a single-phase conductor generating a first magnetic field. The device includes a device installed in the first electromagnetic field, able to generate a magnetic counter-field.
