中文摘要:
      以仿真和实验为研究手段,对船舶超大空间内油池火的燃烧特性进行了系统研究,得出火灾发生时,烟气沉降速度、温度上升速度非常快,灭火行动最好在2min以内展开;同时利用实验方法对人员利用多功能水枪和泡沫灭火系统灭火分别展开研究。研究发现,使用多功能消防水枪对10m2的油火进行控制,灭火进攻的角度、开花水枪的使用对灭火效果有着直接影响,其中以同侧对角进攻的效果最佳,仅仅用了20s就扑灭了10m2柴油火;而泡沫系统灭火的效率非常高,14m2的油火灾在喷淋20s左右得到很好的压制,在喷淋30s彻底被扑灭,这些研究结论将直接用来指导船舶大空间火灾的扑救工作.
英文摘要:
      By the means of simulation and experiment, the combustion characteristics of oil pool fire in the super-large space of ship were systematically studied. The results showed that the smoke settling velocity and temperature rise very fast when a fire broke out, thus the firefighting should start within two minutes. At the same time, the firefighting effects of multi-function water gun and foam fire extinguishing system were studied respectively by means of experiment. The results indicated that when using the multi-function water gun to put out 10-square-meters oil fire, firefighting angle and the using of flowering water gun had a direct impact on firefighting effect, among them the diagonal attack on the same side were best, which took only 20s to extinguish the 10-square-meters diesel fire. While the firefighting efficiency of foam system was very high, 14-square-meters oil fire was suppressed well after the spraying for about 20s, and completely extinguished within 30s. These research conclusion could be used directly for the instruction of firefighting work for large space of vessels.
