Abstract
A burner nozzle for delivering fuel to a burner flame in a furnace includes an inner cylinder and an outer cylinder that are both hollow. The inner cylinder is at least partly disposed within the outer cylinder and axially aligned with it, and is movable in an axial direction relative to the outer cylinder. One end of the inner cylinder has at least one outward projection extending in a radial direction from the outer surface of the cylinder, this projection serving to decrease the free cross-sectional area between the inner cylinder and the outer cylinder at that end of the inner cylinder.
