A regenerable filter for use with exhaust gas streams containing combustible particles, the filter including a filter medium upon which the particles build up as the filter medium removes the particles from the gas stream, a scraper to remove the particles, except for a precoat, from the filter medium, and a burner to burn the removed particles outside the main exhaust gas exit.

A regenerable filter for exhaust gas streams containing combustible particles wherein said exhaust gas streams pass through a filter medium which is provided to remove said combustible particles from said exhaust gas streams and to cause said combustible particles so removed to build up upon a surface of said filter medium, comprising: a sealed housing having a entry conduit and an exit conduit for passage of said exhaust gas streams into and out of said sealed housing, respectively; at least one filter medium having at least one porous surface and being disposed within said sealed housing between said entry conduit and said exit conduit so that said exhaust gas streams can flow into said sealed housing at said entry conduit, through said at least one porous surface and out of said sealed housing at said exit conduit, said at least one filter medium being sealed relative to said exhaust gas streams to prevent passage of said exhaust gas streams to said exit conduit except through said at least one porous surface, combustible particles building up upon said at least one porous surface as said exhaust gas streams flow through said at least one porous surface; means disposed within said sealed housing in close proximity to said at least one porous surface for removing said combustible particles from said at least one porous surface while leaving a thin precoat of said combustible particles on said at least one porous surface; and, means disposed within said sealed housing and in close proximity to said at least one porous surface and out of the flow path of said exhaust gas stream for burning said combustible particles as said combustible particles are removed from said at least one porous surface by said removing means.
