工业仓库的排烟和消防安全 能源与环境学院 赵淘 312010080704205 摘要 本文的目的是证明一个解决方案的可行性，它就是为在工业仓库里工作的人们提供足够的安全保障，重点就是一个工业仓库的排烟系统性能的评价和出口分布情况。同时使用简单的计算和计算机建模技术来完成可用安全疏散时间和必须安全疏散时间的定量分析。这项研究包括灵敏度分析，以探讨在设计火灾中多个火灾场景的变化，通风条件和出口的数量。 在一个有适当大小屋脊通风口的工业仓库内，用计算机模拟火灾增长和烟雾扩散可以揭露一些令人关注的烟运动模式。我们探讨了确定可维持在通风良好的挑高空间的过程。这个研究的结果证明了对既定准则可替代方案的可接受性。还探讨了建模技术的局限和未来的研究方向。 关键词 评估 性能 烟囱效应 可持续 Smoke venting and fire safety in an industrial warehouse By Zhao Tao Abstract The intention of this paper is to demonstrate the feasibility of a performance-based solution for providing adequate life safety levels for the occupants of an industrial warehouse. Focus was given to the evaluation of the performance of a smoke venting system and the exit distribution in an industrial warehouse. Quantitative analyses of the available safe egress time and the required safe egress time were carried out using both a simple calculation and a computer modelling technique.The study included a sensitivity analysis to investigate multiple fire scenarios involving variations in design fires,ventilation conditions and number of exits. Computer simulations of fire growth and smoke spread in a large warehouse with a proportionally large ridge vent revealed somewhat interesting smoke movement patterns. The procedure for determining tenability in a well-ventilated high ceiling space is discussed. The result of the study demonstrated the acceptability of the alternative design solution against the established criterion. The limitations of the modelling technique and future research topics are also discussed.
