Air pollution control (APC) systems are large users of electrical energy in a steel plant. This paper will explore the operational results of the installation of a new low-resistance filter media at the Steel Dynamics Inc. – Roanoke Bar Division (SDI-VA) plant, which resulted a significant reduction in electrical energy used by the APC system. The reduced filter resistance of the new media allowed SDI-VA to remove one fan from operation while maintaining proper meltshop evacuation, resulting in an overall reduction in power requirements and a net savings of more than US$400,000 per year. Data and strategies will be analyzed for application in other electric arc furnace facilities.
