PROBLEM TO BE SOLVED: To prevent decrease in an expansion ratio in high expansion foam fire-extinguishing equipment.SOLUTION: The high expansion foam fire-extinguishing equipment comprises a foaming machine including a foaming machine body formed into a cylindrical shape, a foam screen provided at a tip end side of the foaming machine body, and emission nozzles provided at a rear end side in the interior of the foaming machine body and emitting foam solution towards the foam screen. The emission nozzles are disposed at equal intervals on a vertical cross section of the foaming machine body orthogonally crossing with the emission direction of the foam solution. In the emission nozzles disposed at equal intervals, a flow rate of emission nozzles located at an outer peripheral side on the vertical cross section is reduced compared with a flow rate of an emission nozzle located at a substantially center on the vertical cross section. |
