Abstract Burner device and method Burner device (100) having a longitudinal axis (L), a fuel outlet and an oxidant outlet, 5 further comprising an inner tube (110), carrying an oxidant up to the oxidant outlet in the inner tube, and an outer tube (120), arranged concentrically with the inner tube and carrying a fuel up to the fuel outlet in the outer tube. The invention is characterised in that the oxidant outlet is at least one aperture 10 (112,113), directing the oxidant at a primary oxidant angle (b) of between 450 and 82.5" from the longitudinal axis, in that the fuel outlet is at least one aperture (122,123), directing the fuel at a fuel angle (a) of between 450 and 82.50 from the longitudinal axis, and in that the fuel angle is at least as large as the primary oxidant angle. 15 The invention also relates to a heating method.
