Abstract
A method of optimizing the collection efficiency of a dry-process electrostatic precipitator which is preceded by an evaporative cooler, wherein liquid is sprayed into the evaporative cooler at a rate which is controllable to maintain a desired temperature includes the steps of intermittently measuring the dew points of acid separately and setting the desired temperature T.sub.c in dependence on the measured dew point of acid and a preselected margin of safety .DELTA.T, in accordance with T.sub.c =T.sub.s +.DELTA.T, determining a desired input current I.sub.c for the electrostatic precipitator at T.sub.c and storing I.sub.c, and continuously calculating the deviations of the actual input current I of the precipitator from the desired input current I.sub.c and initiating the measurement of the dew point T.sub.s of acid in response to a predetermined deviation to update the desired temperature T.sub.c.
