The electrostatic precipitator (ESP) is a key pollution control component in air pollution control devices for oil and coal-fired industrial boilers. Within the electrostatic precipitator, fly ash particles are charged electrically due to a corona current from discharge electrodes. In wet or humid environments (such as the wet ESP) the electrodes must be made of expensive corrosion resistant alloys. This paper discusses the development of a novel nanocomposite electrode using carbon nanofibers in a polymer matrix. For the nanocomposite electrode to be a potential replacement for the traditional metal electrode, it must demonstrate good voltage-current characteristics. Experimental work was carried out with composite electrodes that had a polypropylene matrix which was preloaded with carbon nanofiber and microfibers. The results showed that carbon nanocomposite electrodes can perform as well as, or better than metal electrodes in ESPs.
