ESPs work on the principle that opposites attract to each other. In plate wire precipitators, exhaust gas flows through parallel plates of sheet metal. Between each row of plates hangs a row of high voltage electrode. This design allows many flow lanes operating in parallel. Therefore, they are well suited to handle large volumes of exhaust gas. As the exhaust gas passes between the plates, high voltage applied to the electrodes cause the particulate in the gas stream to become negatively charged. The negatively charged particulate is attracted to the positively charged plates and is collected on the plates. Wrappers shake lose particulate from the plates, which falls into collection hoppers for removal.
