内混烧嘴具有短焰，大调节比，火根稳定的特点。法兰式空气和燃气可旋转接口简化了烧嘴管路的配置。NM烧嘴可以在低压助燃空气和燃气下（17.6mbar)正常工作。精密设计，点小火管路螺纹连接，火焰控制接口，观火镜都是标准配置。
The NOZZLE MIX burners feature short flames, wide turndown ranges and very stable combustion. Flanged air and gas rotatable entries simplify burner piping manifolds. The NM burners will develop their nominal ratings with low air and gas pressures (4 OSI = 17,6 mbar). Precision designed, threaded connections for pilots, flame control and peepsight locations are standard on all units.
