Patent abstract
A particulate separator includes a plurality of perforated screens which remove ash particulate from flue gas. A rapper assembly dislodges ash deposits on the perforated screens by exerting a vibrating force thereon. Shafts, which are operatively connected to a rapping device, are received in the openings of perforated screens and welded thereto. The rapper exerts a force on the shaft, which, in turn, vibrates the perforated screen. The vibration of the perforated screens causes the ash deposits to fall off into the hopper.
