The report gives results of a study of the A.P.T. electrostatically augmented particle by particle (EPxP) dry scrubber. It is analogous to a venturi scrubber except that it uses relatively large solid particles (instead of water drops) as collection centers for the fine particles in the gas stream. It is a novel device for controlling fine particle emissions at high temperatures and pressures. Bench scale (0.5 and 1.1 A cu m/min) and pilot scale (4.8 A cu m/min) experiments were run at 20-820 C to determine the performance characteristics of the system. Experimental results show that the EPxP dry scrubber can operate at high temperatures and that its particle collection efficiency can be increased by precharging the particles and by polarizing the solid collectors. The report describes both the system and the experimental results.
