Abstract
The report summarizes recent experience with three agents--sulfamic acid, ammonium sulfate, and ammonium bisulfate--used to regulate the electrical resistivity of fly ash in electric generating stations to ensure satisfactory collection of fly ash in electrostatic precipitators (ESPs). It presents information about the effectiveness of these agents in pilot- and full-scale ESPs. It also presents the limited information available from practical trials of these agents concerning their conditioning mechanisms. It discusses in detail the fundamental physical and chemical properties of the agents that are relevant to fly-ash conditioning. From this information and the results of ESP tests, the report offers tentative conclusions about conditioning mechanisms. Finally, the report briefly discusses the economic aspects of using each of the agents as a conditioning substitute for sulfur trioxide.
