A burner device () having a longitudinal axis (L), a fuel outlet and an oxidant outlet, includes an inner tube () carrying an oxidant to the oxidant outlet in the inner tube, and an outer tube () arranged concentrically with the inner tube and carrying a fuel to the fuel outlet in the outer tube. The oxidant outlet includes at least one aperture () directing the oxidant at a primary oxidant angle (b) of between 45&#xb0; and 82.5&#xb0; from the longitudinal axis, and the fuel outlet includes at least one aperture () directing the fuel at a fuel angle (a) of between 45&#xb0; and 82.5&#xb0; from the longitudinal axis, the fuel angle being at least as large as the primary oxidant angle. A related heating method is also provided.
