Abstract |
The report gives results of an evaluation of the effectiveness of a 1700 cu m/hr (1000 cfm) portable electrostatic spray scrubber in controlling fine particle emissions. The multiple-pass scrubber, designed, constructed, and tested by the University of Washington, combines oppositely charged aerosol particles and water droplets in two water spray towers. Negatively energized aerosol charging sections (coronas) precede each spray tower. The pilot plant was tested on artifically generated dioctyl phthalate (DOP) aerosol and on emissions from a pulverized coal-fired boiler. The overall mass collection efficiency for the two DOP tests was 24.98% and 99.6%, respectively. The coal-fired boiler emission tests showed a collection efficiency for a 0.5 micron diameter particle ranging from 47.0% to 98.0%. Conditions during the 47.0% test included a low water spray rate. Because of the relatively large inlet size distribution, the overall mass collection efficiency decreased only from 99.58% to 96.09% for the two boiler emission tests. |
