ABSTRACT:
Pollutants in a flue gas stream from a dryer of products, such as wood chips, are removed by a pollution abatement system that includes an electrified filter bed unit for removing solid particulates. To prevent deteriorated operation of the electrified filter bed unit due to condensation of volatile organic compounds, the flue gas stream is heated, prior to admission to the electrified filter bed unit, to a temperature sufficient to convert condensable liquid aerosols to a gaseous state. The electrified filter bed unit then removes solid particulate selectively without collecting condensable organics. After the flue gas stream has passed through the electrified filter bed unit, gaseous pollutants can be removed by an oxidation process, for example.
