Abstract
The report gives results of tests of a 1700 cu m/hr University of Washington Electrostatic Spray Scrubber pilot plant on a coal-fired boiler to demonstrate its effectiveness for controlling fine particle emissions. The multiple-pass, portable pilot plant combines oppositely charged aerosol particles and water droplets in two water spray towers. Aerosol negative-charging sections precede each spray tower. The scrubber was tested in two modes: two-stage, including two active particle charging corona sections and two spray towers; and single-stage, including only one corona section and one spray tower. Simultaneous inlet and outlet source tests provided both size-dependent and overall mass basis particle collection efficiency information. Measured overall particle collection efficiencies ranged from 99.30 to 99.99%, depending on scrubber operating conditions, inlet particle size distribution, and mass concentration. Particle mass concentrations measured at the scrubber outlet ranged from 0.00041 to 0.0027 g/cu m. The average overall particle collection efficiency for all tests performed in the two-stage mode was 99.93%; single-stage average efficiency was 99.83%.
