The report gives results of a theoretical and experimental evaluation of the control of fugitive particle emissions (FPE) with a Spray Charging and Trapping (SCAT) Scrubber that uses an air curtain and/or jets to contain, convey, and divert the FPE into a charged spray scrubber. Experiments on a 225 cu m/min bench-scale scrubber verified the theory and feasibility of collecting FPE with charged water spray. The effects of charge levels on drops and particles, nozzle type, drop size, gas velocity, and liquid/gas ratio on collection efficiency were determined experimentally. Results show that collection efficiency can be improved by charging the water and/or particles. Measured particle penetration agrees with theoretical predictions for the un-augmented scrubber. For the electrostatically augmented scrubber, measured penetration is lower than predicted. An air curtain was developed for conveying the FPE to the spray scrubber. The design and air flow field for the air curtain are presented. A prototype SCAT scrubber was built to study the effect of crosswind and hot buoyant plume. The air curtain was successful in deflecting crosswind up to 15 mph and containing a hot buoyant plume. Theories were developed for predicting the trajectories of the air curtain jet stream and the hot buoyant plume.
