The utility model provides a high-reliability swirl burner nozzle. The outer end of a nozzle of the annular swirl burner is welded with a laminated steel pipe through an alloy steel pipe, and a wear-resistant ceramic layer arranged in the nozzle and the laminated steel pipe are embedded and assembled together through a dovetail. According to the utility model, the swirl burner does not deform after being heated. Enough rigidity can be kept, certain elasticity is achieved, and the mechanical strength of the nozzle can be improved. And the wear-resistant ceramic can be prevented from falling off. The swirl burner nozzle is suitable for being used as a high-reliability swirl burner nozzle.
