Abstract
The invention proposes a vortex generating arrangement, especially for a pre-mixing burner of a gas turbine, having an air conducting channel of predetermined height extending between two essentially parallel channel walls and having a predetermined direction of air flow, and having a plurality of vortex generators arranged in the channel. An improved mixing is achieved by the vortex generators each having the shape of a triangular plate, which is arranged essentially perpendicular to the channel walls and oriented relative to the direction of air flow with a predetermined off-axis angle ≠0°, and a first side of the triangular plate being oriented perpendicular to the channel walls.
