The report gives results of fractional and overall mass efficiency tests of two Apitron electrostatically augmented fabric filter dust collectors. The tests were performed on a mobile pilot-scale system collecting flyash produced by a pulverized-coal-fired industrial boiler and on a full-scale pilot plant collecting redispersed silica dust. Total particulate concentrations were determined at the inlet and outlet of both devices. Inlet and outlet emission rates, as a function of particle size, were determined from about 0.5 to 8 micrometers on a mass basis using cascade impactors, and from about 0.01 to 1.0 micrometers using electrical mobility and optical techniques. Total mass efficiency for the mobile system was 99.90-99.94%; fractional efficiencies for the 0.2-1 micrometer particle size range were 99.85-99.94%. Total mass efficiency for the full-scale pilot system was 99.995-99.9994%; fractional efficiencies in the 0.2-1 micrometer size range were 99.90-99.999%.
