Abstract
The paper describes a project to expand the data base of sulfur oxide concentrations, in situ fly ash resistivities, and electrical operating points measured in operating utility fly ash electrostatic precipitators (ESPs). Recent data are presented. In situ resistivity data are compared with laboratory measurements and mathematical predictions. Electric generating plants burning medium-sulfur coal need a way to predict when ESP performance will be limited by high resistivity of the collected fly ash. The main uncertainty in mathematical predictions of fly ash resistivity lies in the marginal effect of sulfur trioxide vapor naturally occurring in the flue gas. A revised version of the resistivity predictor gives results in agreement with values measured both in situ and in the laboratory.
