This 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.
