This report provides guidance for evaluating air pollutant control technologies for electric arc furnaces in the iron and steel foundry industry. It includes estimated emission factors, a discussion of emission characteristics, and lists of references resulting from an extensive literature search. Control technologies, including equipment for evacuating emissions during melting, refining, charging, and tapping, as well as dust collection equipment, are presented. Emission data from several field tests on electric arc furnaces carried out by EPA and others are reported. Capital and annualized emission control costs for several new and retrofitted model plants are presented. The environmental impacts (estimated emissions, solid waste disposal, energy requirements, water pollution, and noise) for model plants are included. Several regulatory options corresponding to different levels of emission control costs, energy requirements, and environmental impacts are presented. The document outlines enforcement aspects and contains appendices with detailed field test data on existing furnaces and cost data for several model furnaces in iron and steel foundries.

This report summarizes findings of a study to identify control technology for electric arc furnaces in the gray iron and steel foundry industry. A general description of the industry is followed by a presentation of emission rates and composition of exhaust gases. Emission control technology is discussed for melting, chargin and tapping of the furnace. Several new, or novel control techniques are discussed in addition to conventional technology. Cost estimates for several control options are presented. Adverse environmental effects concern energy requirements and dust disposal and are also explored. Sampling techniques for furnace emissions are discussed, and several formats for writing an emission regulation are identified. Finally, the effect of each regulatory format on reducing furnace emissions is summarized.
