The report gives results of an evaluation of the performance of a fabric filter system controlling emissions from either one or two 30-ton electric arc furnaces producing a high-strength, low-alloy specialty steel. The evaluation involved measuring the system's total mass collection efficiency and apparent fractional collection efficiency. Testing involved 8 sampling days with one furnace operating, and 2 days with two furnaces. Baghouse influent and effluent streams were sampled with total mass samplers, inertial impactors, a condensation nuclei counter (CNC), and an optical dust counter. The influent and effluent total fluoride concentrations were measured for three of the tests to estimate the particulate and gaseous fluoride levels to which the Dacron filter bags are exposed during normal service. Total mass tests showed baghouse mean mass efficiency to be 97.9% with one furnace operating, and 98.7% with two furnaces. Mean mass concentrations for one- and two-furnace operation were 0.0014 and 0.0019 grains/dscf, respectively. Influent impactor tests showed considerable size distribution differences as a function of the phase of the process: the greatest concentrations for the particles sized occurred during the first melt. Effluent impactor size distribution tests suggested agglomeration. (Portions of this document are not fully legible.)
