The resistivity of fly ash is often too high under a particular set of operating conditions to permit the most efficient use of an electrostatic precipitator. A variety of substances, generally referred to as conditioning agents, can be added to the boiler or to the effluent gas downstream to attenuate the high resistivity. The report gives results of a review of recent research, including the results of two field tests of sodium conditioning, on the effects of sodium content on the electrical resistivity of coal fly ash. It presents a procedure for calculating the amount of sodium that must be added to reduce fly ash electrical resistivity to a desired value. It discusses advantages and disadvantages of sodium conditioning for reducing fly ash resistivity.
