The electrostatic precipitation of dusts

A brief introduction to the basic electrostatic types is given and on this is based a discussion of the theoretical considerations• Some basic design factors are mentioned together with the performance desired and relative costs. The efficiency of a precipitator is then introduced from a theoretical viewpoint and an example is used to demonstrate the practical size frequency method of efficiency determination. Some of the problems encountered in existing precipitators are considered in an attempt to indicate the deviations from theory commonly noticed.
