Abstract
An ultrasonic burner system for regenerating a filter comprises an ultrasonic atomizer for atomizing fuel oil into fine droplets and a combustion chamber that is adapted to pass a exhaust gas created therein by the combustion of the fine droplets toward the filter to regenerate the filter by burning previously unburnt matter trapped thereby, wherein the fine droplets are burned in such a manner that the exhaust gas is at a higher temperature in the wall region than in the axially central part of the combustion chamber. Consequently, the combustion chamber can be made compact, and since the temperature of the combustion gas flowing in the combustion chamber is made higher in the wall region than in the axially central part of the combustion chamber, the temperature distribution in the filter can be made uniform.
