Abstract: From the exhaust gas of a Diesel engine, carbon black is filtered out by a ceramic carbon black filter. To regenerate said carbon black filter, it is burned out by means of a burner comprising a swirl nozzle provided with liquid fuel and air. The burner is operated with a supergreased fuel/air mixture, and in the main combustion chamber there is produced a stable flame burning sootlessly. The combustion gases are mixed with the exhaust gases in a transverse flow mixer and the residual fuel amount is burned off in a secondary combustion chamber by air contained in the exhaust gas. Regeneration may take place during the operation of the engine, while the burner flame is not put out by the pulsating engine pressure.

Abstract: A method and apparatus for the combustion or gasification of highly viscous nd/or suspended fuel in a burner flame. The fuel is introduced, in a nozzle, and in the form of a continuous, thin, annular layer, into a stream of atomizing medium, with the aid of which the fuel is atomized. The fuel is guided onto the inner wall of the nozzle as a continuous film at a velocity that is low with regard to wear action. The fuel is atomized at a terminal portion of the nozzle that has a knife-edge configuration. The fuel and the atomizing medium stream that flows within the annular film discharge at a minor resonant velocity.
