Abstract :
The application of a saturable-reactor control system to an existing glass furnace, for melting a glass of composition between a soda-lime and a borosilicate, is described. The factors that influenced the selection of the specific equipment design are discussed as well as the performance characteristics that were achieved. A phase imbalance has been observed. It is concluded that the best way to reduce this phase imbalance would be to redesign the furnace for 100% bottom electrodes. Given the present arrangement, an SCR autotap system would improve control. This change would provide a higher power factor over a wide operating range without manual tap changers.<>
