In a premixing burner (100), which is composed essentially of at least two conical part shells (101, 102) fitted one in the other in the direction of flow, their longitudinal axes of symmetry are offset relative to the burner axis in such a way that the adjacent walls of these part shells form, in their longitudinal extent, tangential air inlet slits (119, 120). A combustion air stream (115) flows through these into the interior (114) of the premixing burner. Arranged on the head side of the premixing burner is a nozzle (103) which is preferably operated by means of a liquid fuel (112), whilst arranged along the tangential air inlet slits are further nozzles (117) which are preferably operated by means of a gaseous fuel (113). The fuel line for supplying the last-mentioned fuel (113) is formed by a continuation of the respective part shell, in that the end of the latter is bent round in the region of the tangential air inlet slits and is closed in a sealed manner relative to the corresponding part shell outside the inflow region of the tangential air inlet slits.
