A premix burner (1) essentially comprises at least two sectional cone bodies (12, 13) which are nested one inside the other in the direction of flow and the respective cone axes of which are offset relative to a center axis (10). Tangential slots (16) are thereby formed for the combustion air (9). Starting from the tip of the sectional cone bodies (12, 13), a feed lance (1) is arranged which extends downstream into the interior of the premix burner (11) and runs essentially symmetrically to the center axis (10). At least one fuel nozzle (8) is arranged at the downstream end of the feed lance (1).
