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 profiles arranged along the circumference. In this case, the profiles are to be formed by corresponding sections of components which are arranged to be axially movable relative to one another. One respective section of a profile is to be a hollow body in which the corresponding other section engages in a movable manner. With the burner, a combustion is made possible that is low in pollutants while the swirling efficiency and the rotational swirl development are optimal.
