ABSTRACT:
In premixing-type combustion of liquid fuel in a burner without a premixing section, a conical column (5) of liquid fuel is formed in the interior (14) of the burner, which column widens in the direction of flow and is surrounded by a rotating stream (15) of combustion air which flows tangentially into the burner. Ignition of the mixture takes place at the burner outlet, a backflow zone (6) forming in the region of the burner outlet. The burner itself consists of at least two hollow part-cone bodies (1,2) which are superposed on one another and have a cone angle increasing in the direction of flow. The part-cone bodies (1, 2) are mutually offset, so that tangential air inlet slots (19, 20) are formed. A nozzle (3) placed at the burner head ensures injection of the liquid fuel (2) into the interior (14) of the burner.
