PROBLEM TO BE SOLVED: To provide a foam nozzle for a foam extinguishment facility for improving a foaming performance to attain a sufficient foaming performance even with a protein extinguishment agent.SOLUTION: A foam extinguishment facility foam nozzle comprises: a nozzle body 1 having a nozzle portion 5 for injecting an extinguishing aqueous solution; and a foaming cylinder 2 attached to the leading end of the nozzle body 1 for injecting the extinguishing aqueous solution injected from the nozzle body 1, in a foamy state. A portion of either the nozzle body 1 or the foaming cylinder 2 is equipped with an air intake port 9. A foaming net member 10 is arranged along the inner circumference of the foaming cylinder 2 so that a large velocity difference is made between the center side and the inner circumference side of the foaming net member 10 so that the extinguishing aqueous solution and the air are sufficiently mixed. |
