ABSTRACT:
A burner with a conical shape opening in the flow direction is composed of two partial-conical bodies, which are positioned one upon the other and whose centerlines in the longitudinal direction extend offset relative to one another. Because of this offset, a tangential inlet slot to an internal space of the burner is formed in each case over the length of the burner. The fuel supply takes place centrally via a nozzle and tangentially in the region of the inlet slots via, in each case, a fuel line, which is provided with fuel openings which there undertake the injection of the fuel. A duct is formed above each inlet slot and this is equipped with an injector. A further fuel is introduced through this injector. The air/fuel mixture with fuel from the injector and/or fuel from the fuel line flows generally as an air/fuel mixture through the tangential inlet slots into the internal space of the burner. If needed, further mixing with the fuel from the nozzle takes place there.
