Coal water slurry-natural gas combined gasified nozzle

The utility model relates to a coal water slurry-natural gas combined gasified nozzle. The coal water slurry-natural gas combined gasified nozzle comprises an ignition bar, an ignition fuel gas center pipe, an internal oxygen ring pipe, a coal water slurry ring pipe, a natural gas ring pipe, an external oxygen ring pipe and a cooling ring pipe which are coaxially sheathed sequentially from inside to outside. The lower end of the coal water slurry ring pipe extends downwards to form a coal water slurry-natural gas mixing cavity, the lower end of the natural gas ring pipe is connected with the outer wall of the lower part of the coal water slurry-natural gas mixing cavity, a natural gas spout is formed in the coal water slurry-natural gas mixing cavity, the natural gas ring pipe is communicated with the interior of the coal water slurry-natural gas mixing cavity through the natural gas sprout, and a mixture sprout is formed in the lower part of the coal water slurry-natural gas mixing cavity.
