Zusammenfassung:PROBLEM TO BE SOLVED: To provide a foam fire-extinguishing apparatus and foam fire-extinguishing system including a foam nozzle capable of discharging fire-extinguishing foam to a fire-extinguishing object extending in a vertical direction.SOLUTION: The fire-extinguishing apparatus includes a foam nozzle that discharges fire-extinguishing foam outward. The foam nozzle has a hollow rod shape, and the side wall of the foam nozzle defines a plurality of discharge outlets for discharging an aqueous solution including fire-extinguishing foam, supplied in the hollow part, to the outside in a foam form. The foam nozzle is so disposed as to extend in a substantially horizontal direction, and the plurality of discharge outlets are not provided inside a vertical plane including a center line of the foam nozzle but provided on at least one semi-cylindrical part of two semi-cylindrical parts divided by the vertical plane. 【課題】鉛直方向に延在する消火対象物に対して泡放出することが可能なフォームノズルを備える泡消火設備及び泡消火システムを提供することである。【解決手段】外方に泡放出するフォームノズルを備え、前記フォームノズルは中空棒状であって、前記フォームノズルの側壁は、中空部内に供給された泡消火剤を含む水溶液を泡放出する複数の放出口を区画しており、前記フォームノズルは、略水平方向に延在するように配置され、前記複数の放出口は、前記フォームノズルの中心線を含む鉛直平面内には設けられておらず、前記鉛直平面で分けられる2つの半筒部のうち少なくとも一方の半筒部に設けられている。【選択図】図1
