89/ 163 13 A burner (1) with a conical shape opening in the flow direction is composed of two partial-conical bodies (2, 3), which are positioned one upon the other and whose centerlines (2a, 3a) in the longitudinal direction extend offset relative to one another. Because of this offset, a tangential inlet slot to the internal space (17) of the burner (1) forms in each case over the length of the burner (1) The fuel supply takes place centrally via a nozzle (9) and tangentially in the region of the inlet slots via in each case, a fuel line (10, 11), which is provided with fuel openings (21) which there undertake the injection of the fuel (6). A duct is formed above each inlet slot and this is equipped with an injector (12, 13). A further fuel (4) is introduced through this injector. The air/fuel mixture with fuel from the injector (12, 13) and/or fuel from the fuel line (10, 11) flows generally as an air/fuel mixture (8) through the tangential inlet slots into the internal space (17) of the burner (1). Further mixing with the fuel (5) from the nozzle (9) takes place there, if need be. (Fig- l)
