研究了细水雾灭火系统对铁路隧道救援站火灾的扑救性能。试验在铁路隧道救援站全尺寸模拟隧道平台上开展,研究了隧道内不同纵向通风条件下,细水雾灭火系统作用前后隧道内的温度场、燃烧成分、火源热辐射参量的分布及变化。结果表明,细水雾灭火系统可有效抑制模拟隧道内火灾,验证了细水雾灭火系统在铁路隧道救援站内的可行性和有效性。
Studied the water mist extinguishing system on the railway tunnel rescue station fire fighting performance. The experiment was carried out on a full-scale simulated tunnel platform of railway tunnel rescue station. The distribution and changes of temperature, combustion composition and thermal radiation parameters of the tunnel before and after the action of the water mist extinguishing system were studied under different longitudinal ventilation conditions in the tunnel. The results show that the water mist fire extinguishing system can effectively suppress the fire in the simulated tunnel and verify the feasibility and effectiveness of the water mist fire extinguishing system in the railway tunnel rescue station.
