| 摘要 |
The invention provides a glass melting furnace in which glass is heated in several parallel adjacent zones by passage of glass between rows of electrodes situated at and defining the lateral boundaries of the zones. The bottom wall of the furnace chamber is formed with a network of channels for withdrawing glass from the lower part of the furnace towards an outlet. The electrode rows are connected to output terminals of an alternating current supply circuit which is fed from a three-phase alternating current supply source and has a transformer means for distributing the electrical load preferably substantially equally to the phases of the polyphase source. |
