Riddel, J W

A diesel engine exhaust cleaner and burner system includes at least one exhaust cleaner member with a filter positioned therein to effect removal of particulates from a stream of exhaust gas delivered thereto via an inlet manifold. A fuel burner supplied with fuel by a fuel nozzle is operatively associated with the inlet manifold to supply the necessary heat to effect incineration of particulates collected on the filter. A cyclone duct providing a vortex chamber therein is operatively positioned downstream of the fuel nozzle and is supplied with sufficient air so as to effect both the complete combustion of the fuel and the controlled incineration of the particulates by increasing the residence time of the fuel in the reaction region within the vortex chamber and also effecting a more uniform distribution of the heat of combustion across the inlet face of the filter for the uniform heating of the particulates thereon to their combustion temperature.
