| Abstract | The successful operation of DC plasma arc furnaces depends to a large extent on gaining a fundamental understanding of the arc phenomenon itself, and ensuring its presence in the furnace at all times. This is particularly important when operating in brush-arc mode, where the electrode tip is located in close proximity to the slag. A method for confirming the presence of an arc in a DC circuit has been developed and successfully demonstrated on medium-scale pilot-plant facilities using characteristic frequency spectra on the anode-cathode voltage caused by the arc dynamics. The system has since been applied to a large-scale industrial furnace. Taking into account the order of magnitude differences in electrical and geometrical scale, the results are consistent with those obtained on pilot-scale tests, demonstrating that the arc-detection technology is applicable to production-scale furnaces. |
