The report gives results of a demonstration of the effectiveness of a 1700 cu m/hr (1000 acfm) University of Washington (UW) Electrostatic Spray Scrubber in controlling fine particle emissions from an electric-arc steel furnace. The two-stage portable pilot plant operates by combining oppositely charged aerosol particles and water droplets in two water spray towers. Aerosol charging sections (coronas) with negative polarity precede each spray tower. Simultaneous inlet and outlet source tests utilizing UW Cascade Impactors--Mark V for the inlet and Mark III for the outlet--provided both size-dependent and overall mass basis particle collection efficiency information. Measured overall particle collection efficiencies ranged from 58.8 to 99.5%, depending on the electrostatic scrubber operating conditions and on the inlet particle size distribution. Tabular and graphic data is presented illustrating the effects of the corona specific plate area, liquid to gas flow rate ratio, magnitudes of particle and droplet charging voltages, and electrostatic polarities on the overall particle collection efficiencies and on the particle collection efficiency as a function of particle size.
