ABSTRACT:
In a filter cartridge for insertion in a housing for the removal of combustible substances from exhaust gases, with a regeneration of the charged filter material by combustion of the substances, the filter consists of a metallic fiber mat welded together so as to form a hollow cylinder which is disposed tightly on an electrically conductive lattice structure. The ends of the hollow filter cylinder are compressed and tightly held, by metal sleeves, in engagement with a cartridge head and a cartridge foot structure and they are welded together by an end face weld seam. Current is supplied to the filter cylinder by way of the cartridge head and foot structure for heating the filter cylinder directly so that the combustible substances collected on the inside of the filter cylinder are efficiently burnt.
