Description:
The report gives results of an investigation of particle charging in positive and negative corona discharge as a function of temperature from 38 to 343C in order to establish, especially at hot-side electrostatic precipitator (ESP) temperatures, the relative effectiveness of the two possible methods of charging. Charge values on individual particles exiting two laboratory ESPs were measured in an experimental apparatus utilizing a Millikan cell. Measurements were directed at fine particles with radii between 0.3 and 1.5 micrometers. Measurements were obtained for redispersed fly ash particles carried in air at temperatures from 38 to 343C. The electrode geometries and electrical operating conditions utilized were typical of full-scale ESPs.
