The investigation was the first phase of a program to develop a pilot electrostatic precipitator test facility. The facility was to study the effects of various operating conditions on precipitator collection efficiency for fly ash from western coals.

A plate-type pilot electrostatic precipitator was built and modified to increase its applicability to the problems studied.

Results of tests9 run to determine the effect of temperature on collection efficiency for fly ash from a single sources indicated the existence of an optimum operating temperature. Test results also showed that the coal and fly ash composition have an effect on precipitator collection efficiency and particle resistivity.

The need for more applicable particle resistivity measurements was determined. Recommendations were made with regard to improving the usefulness of the resistivity measurements and the pilot electrostatic precipitator test system.
