摘要： 针对全氟己酮灭火系统在局部应用场景下的灭火性能进行试验研究，选取70B油盘火、立体火和木垛火3种典型的火灾模型，设计搭建局部应用灭火试验平台，测试灭火剂量、喷射时间、灭火时间、喷嘴压力等灭火关键参数。结果表明，全氟己酮灭火系统在3种火灾模型下均表现出良好的灭火性能，能够快速抑制火焰并防止复燃；全氟己酮局部应用灭火关键喷放参数为喷嘴压力、喷射角度、喷射时间和雾滴粒径。对于70B油盘火，喷嘴压力大于1 MPa才能压制火焰，成功灭火，但要避免喷嘴压力过大造成飞溅；对于立体火，喷射角度要完全覆盖保护对象且要保证安全裕量大于0.6 m；对于3A木垛火，喷嘴喷射后雾滴粒径DV0.99≤200 μm灭火效果较好。

Abstract: An experimental investigation was conducted to evaluate the fire extinguishing performance of the perfluorohexoane fire suppression system in local application scenarios. Three typical fire models were selected: 70B oil pool fire, three-dimensional fire, and wood crib fire. A test platform for local application fire suppression was designed and constructed to measure key parameters such as agent dosage, discharge time, extinguishing time, and nozzle pressure. The results indicate that the perfluorohexoane system demonstrated excellent fire suppression capabilities across all three fire models, effectively suppressing flames rapidly and preventing reignition. The critical discharge parameters for local application were identified as nozzle pressure, spray angle, discharge time, and droplet size. For 70B oil pool fires, a nozzle pressure exceeding 1 MPa was required to suppress the flames, while excessive pressure should be avoided to prevent splashing. For three-dimensional fires, the spray angle must fully cover the protected object with a safety margin of at least 0.6 m below the midpoint of the object. For 3A wood crib fires, optimal extinguishing efficiency was achieved with a droplet size (DV0.99) ≤200 μm.
