I I INTRODUCTION This paper describes the wavy electrtode precipitator and gives an analy-1 sis of its performance. This advanced electrode design is based on a unique geometrical configuration of electrodes which is expected to provide signifi-I cantly improved performance as well as reduced cost over conventional precipitators. 11 I Overall reviews of electrostatic precipitator technology are given by White (1,2), and Robinson (3). A state-of-the-art precipitator configuration is illustrated in Figure la. The collecting electrodes are typified by baffles which provide plate stiffness and shield the collected particulate layer from direct scouring by the mainstream, particularly during rapping. The ad-I vanced design presented in Figure lb is typified by a wavy collecting electrode shape which provides the same functions with certain advantages. A brief outline of fundamental collection processes is given here to emphasize the advantages of the latter configuration. These processes are ion generation, particle charging. particle capture, particle removal, particle reentrainment, and sparkover. Gas ions are obtained from a corona discharge at the anode to provide a source for particle charging by diffusion and by field charging. Diffusion I charging dominates the charging process for very small particles (submicron DISCLAIMER This report was prepared as an account of work sponsored by an agency of the United States Government.
