Filtering apparatus for filtering particles from high temperature (e.g. greater than 500 degrees C., and at a pressure of about 2-40 bar) gases includes a hollow upright vessel with at least one generally torodial shaped hollow clean gas chamber mounted within it. The gas chamber has a gas impervious peripheral wall with at least one ceramic or sintered metal filter mounted in an opening in the wall. Dirty gas flows through the filter(s) into the clean gas chamber, and then passes through a conduit to be ultimately discharged from the vessel. The torodial shaped chamber may be circular or polygonal (e.g. square) in plan, and circular or polygonal in cross-section; for example it can be constructed solely of flat plates. |
