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.

A process for premixing-type combustion of liquid fuel in a burner in the absence of a premixing section, which comprises forming, in the interior of the burner, a conical column of liquid fuel, which widens in the direction of flow and does not wet the walls of the interior and which is surrounded by a rotating stream of combustion air introduced substantially continuously along the length of said burner and which flows tangentially into the burner, ignition of the mixture starting at the burner outlet, and flame stabilization in the region of the burner outlet being achieved by means of a backflow zone.
