ABSTRACT:
The particle filter for waste gases includes a porous filter body traversed by honeycomb-form channels and resistance heating elements for burning-off of soot particles. The resistance heating elements are in a zone adjacent an entry end of the filter body and include perforated strips of sheet metal including longitudinal strips which are bent into U-shaped heat conductors. Cross strips create, on destruction of individual heat conductors, an electrical current detour path. The resistance heating elements are inexpensive to produce and easy to install.
