Abstract: A fluidized bed scrubber for use in gas cleaning systems, comprising means for introducing a quantity of polluted gas into a first chamber; means for removing a portion of the pollutants from the polluted gas in the first chamber; means for introducing the polluted gas into a second chamber; and means for removing additional pollutants from the polluted gas in the second chamber. The invention also provides a method for cleaning polluted gas, comprising the steps of passing the polluted gas from a combustion source through a fluidized bed scrubber, removing a plurality of pollutants within the fluidized bed scrubber, passing the fluidized gas through a reactor, passing the fluidized gas through a filter in order to remove further quantities of pollutants, and emitting the now-clean gas into the atmosphere.
