Natural gas nozzle suitable for wind tunnel environment

The utility model discloses a natural gas nozzle suitable for a wind tunnel environment, and belongs to the technical field of furnace gas suspension roasting. The natural gas nozzle suitable for the wind tunnel environment comprises a kiln wind tunnel, a plurality of air supply pipes are evenly distributed at the bottom of the kiln wind tunnel in the radial direction, and one end of each air supply pipe penetrates through the kiln wind tunnel, extends into the kiln wind tunnel and is connected with a nozzle body; compared with a traditional spray head, in order to prevent the spray holes from being opposite to the wind direction, the longitudinal spray holes are formed in the top of the spray head and in the leeward face, windward is avoided, the spray holes can be prevented from being eroded and blocked by strong wind mixed with materials, and reverse flapping and tempering can be avoided. 本实用新型公开了适于风洞环境的天然气喷头，属于炉窑气态悬浮焙烧技术领域。适于风洞环境的天然气喷头，包括窑炉风洞，所述窑炉风洞的底部径向均布多个送气管，所述送气管的一端穿过窑炉风洞延伸到内部并连接有喷头；本实用新型有区别与传统的喷头，为了避
