Electrical resistivity is one of the critical parameters influencing the collectability of fly ash by electrostatic precipitation. This report discusses research designed to acquire additional knowledge about the surface conduction process. Transference experiments revealed that the alkali metal ions serve as charge carriers. It was concluded that the attack by certain environmental species, water and acid, on the surface of the glassy ash mobilizes the alkali metal ions. A correlation was established between the magnitude of maximum surface resistivity and the concentrations of lithium, sodium, potassium and iron. The correlation offers a possible means of estimating the resistivity of an ash from the chemical analysis for a given set of environmental conditions.
