ABSTRACT:
A burner for difficult to combust gas mixtures, particularly those including exhaust gases of an internal combustion engine, that is preferably intended for the regeneration of particle filter units in the exhaust gas duct of an internal combustion engine, such as a diesel internal combustion engine. For initiating the regeneration of such so-called soot filter units, the burner generates hot combustion gases at the outlet thereof. The burner includes, at a distance from the discharge opening of a fuel injection nozzle, a baffle barrier that extends approximately perpendicular to the center axis of the fuel injection nozzle. This baffle barrier divides the combustion chamber into an energy-rich zone with a gas mixture prepared to be ignitable and a second zone in which the exhaust gas from the internal combustion engine is diverted. In this way, the burner can also burn even difficult to combust gas mixtures and can reliably maintain, regardless of the operation conditions of the internal combustion engine, a flame in the combustion chamber for generating hot combustion gases.
