Abstract
A burner includes an axis and a configuration which is rotationally symmetrical relative to the axis and includes an outer casing and an inner casing coaxial thereto. The configuration defines an annular gap extending from an inlet to an outlet for guiding a stream of oxygen-containing gas. A multiplicity of nozzles for supplying a fuel to the stream and a swirl lattice are disposed in the annular gap. The configuration including the outer and inner casings is constructed in such a way that the stream flows through the annular gap between the swirl lattice and the outlet at an essentially constant meridional velocity. The burner is particularly suitable for use in a gas turbine.
