PURPOSE:To improve the life of a burner tip, by making a cross sectional form of a widening out and scrambling part with a mixing duct for fuel into a state of a tapered wedge. CONSTITUTION:A mixing duct 3 is provided within a burner tip 7, where fuel 1 and pressure medium, such as vapor and air are mixed up. A final stage fuel duct 5 which scramples for the fuel with the mixing duct 3 is formed in a widening out state toward a downstream side from an upstream side, and a scrambling part for the fuel with the mixing duct 3 is formed in a state of a tapered wedge toward a downstream side 9 from an upstream side 8. The fuel 1 flows in the mixing duct 3 through a fuel duct 4 and the fuel duct 5, which is mixed up with the pressure mediums 2 and sprayed from an opening 10. With this, the life of the burner tip can be improved as friction at the connecting part with an initial stage fuel supply duct 4 is decreased. |
