船舶舱室火灾通道烟气特性研究

Study on smoke characteristics in passageway of ship

有毒有害烟气是船舶火灾发生后最大的危害,对其控制和管理显得尤为重要,但目前相关的研究和应用较少,特别是火灾发生后如何消除烟雾和有害气体的研究更为缺乏。文章通过模拟舱室火灾试验,研究通道烟气的蔓延规律和温度分布情况,获得燃料的热释放速率曲线和质量燃烧速率曲线。通过通道布置的探测点得到了舱室火灾通道烟气运动规律及温度分布情况,为船舶消防损管系统设计中排烟风机的选用、布置、人员逃生和相关消防战术的制定提供参考。

Study on smoke flow and temperature parameters of shipboard fire has significant influence on personnel escape and rescue. Based on the numerical simulation of diesel pool fire in compartment and passageway, characteristics of smoke flow and temperature pattern are studied in this paper. Furthermore, the curve of heat release rate and mass loss rate are respectively drawn. The conclusions will provide theoretical basis for the selection and arrangement on fan（ s）, personnel escape and decision on fire fighting tactics.
