Abstract (en)

[origin: WO2014023462A1] The invention relates to a burner (1), comprising an air supply and premix channel (4) having an essentially annular cross-section, through which air and fuel flow during operation, and which is formed of an outer shell (5) and a hub (6). A plurality of swirl blades (7), which extend from the hub (6) to the outer shell (7) in a radial direction and are provided with a deflection surface (11), are arranged in said burner. In a radial outer region of the swirl blades (7), a downstream flow angle (alpha) to a main flow direction (13) increases at least once and decreases at least once in a radial direction at an outflow end (12) of the deflection surface (11).
