Description:
This report describes tests to evaluate the performance of an electrostatic precipitator installed on a copper reverberatory furnace. Particle size measurements were made with modified Brink cascade impactors in order to calculate the ESP fractional efficiency. The particle size distributions at the inlet and outlet were both found to be bimodal. The overall mass median diameter of the inlet distribution was greater than 10 micrometers. The SRI-EPA computer model was used to simulate the ESP performance. Values of the mass collection efficiency were found by instack filters to be 96.7%, and by cascade impactors to be 96.6%. The computer model predicted an overall efficiency to be 96.8%, which is also the design efficiency. The particulate matter was found to be very cohesive and hygroscopic, and the composition (color) varied from impactor stage to stage. There was no evience of electrical problems due to particle resistivity or space charge.
