Natural gas spray gun

The utility model provides a natural gas spray gun, which belongs to the technical field of smelting equipment and comprises an oxygen-enriched spray gun, a natural gas spray gun, an oxygen-enriched air pipe, a natural gas pipe and an electromagnetic stop valve. The natural gas spray gun is arranged, natural gas is adopted as a reducing agent and fuel, meanwhile, the oxygen-enriched spray gun is arranged, oxygen-enriched gas is introduced to strengthen smelting, carbon emission is low, the environment can be affected, and a large amount of metallurgical slag cannot be generated. Moreover, the spray gun adopts natural gas as a reducing agent and fuel, the ash content is low, the hearth cannot be occupied, and the hearth capacity is high. Natural gas is adopted as a reducing agent and fuel and cannot block the spray gun, maintenance is greatly reduced, a preparation system does not need to be added, and investment is reduced. The utility model is suitable for supplying the reducing agent and fuel of clean energ
