Abstract

A burner for gas turbine engines is provided in which a ring-shaped swirling device is coaxially assigned to a fuel nozzle. The swirling device forms tangential ducts for an adjustable feeding of combustion air between profiled surfaces arranged along the circumference. Two components, which are axially adjustable relative to one another, are to form, on mutually opposite faces, the ducts between profiles and recesses which are arranged offset relative to one another along the circumference, in such a manner that, when at least one component is adjusted, the profiles can be moved into the recesses for a reduction of the duct cross-sections or can be moved out of the recesses for an enlargement of the duct cross-sections.
