Summary:PROBLEM TO BE SOLVED: To provide a smooth transition of flow limiting contours from a swirl generator into a mixing zone.SOLUTION: There is provided a premix burner for operating a heat generator, the burner at least having the swirl generator, a mixing section disposed downstream of the swirl generator and a transition piece for transferring the swirl flow from the swirl generator into the mixing section. The transition piece comprises an inlet connected to the swirl generator, an outlet connected to a mixing tube, and a continuing flow limiting interior contour between the inlet and the outlet. A least in an inlet section, the interior contour is curved radially inwards towards the inner diameter of the mixing tube, and at the outlet, the interior contour is flush with an interior flow limiting contour of the mixing tube.
