A device which separates particles from a gas stream by passing the
carrier gas between pairs of electrodes across which a unidirectional, high-voltage potential
is placed. The particles are charged before passing through the field and migrate
to an oppositely charged electrode. These devices are very efficient collectors of
small particles, and their use in removing particles from
power plant plumes and in other industrial applications is widespread.
