Abstract
An apparatus for removing particulate matter from a biomass combustion gas stream, the apparatus having a mist-producing element that mixes a gas stream entering the apparatus with liquid droplets; a Wet Electrostatic Precipitator (WESP) section that includes ionizing electrodes that electrically charge the particulate matter and the intermixed liquid droplets and collecting surfaces under the influence of an electrical field which attract and remove electrically-charged particulate matter and intermixed liquid droplets from the gas stream; and a scrubbing section that provides for additional scrubbing of the gas.
