The report gives results of theoretical modeling of particulate emission and in-stack plume opacity for the electrostatic precipitator (ESP)/scrubber system at Southwestern Public Service Company's Harrington Unit 1. The theoretical results of an emission rate of 17.8 ng/J and opacity of 35% are in good agreement with data from compliance testing of the unit. The calculations indicate that 20% opacity can be achieved (1) by increasing specific collector area (SCA) of the ESP by 25% and leaving the scrubber pressure drop alone, (2) by increasing scrubber pressure drop by a factor of 4 and leaving the ESP alone, (3) by replacing the existing marble bed scrubber with a venturi scrubber, increasing the pressure drop by 20%, and leaving the ESP alone, or (4) by doubling the SCA of the ESP and removing the scrubber. Calculations showing the impact of high in-stack opacity on the downwind appearance of the plume are also included.
