利用示踪棒测量油料洞库模型坑道烟气流动分区

研究火灾燃烧烟气流动规律,对于掌握初期形式为燃烧的单炕道的火灾的发生和发展,以及爆炸后有持续燃烧的火灾发展规律,具有十分重要的意义。在建立的火灾燃烧模拟实验台上,进行了火灾燃烧实验,利用示踪棒对火灾烟气流动的分区进行了测量,对烟气流动分区现象进行了分析。对"死区"和烟气区内流动和分层现象的研究表明,利用示踪棒测量火灾烟气层高度并定性的揭示流动性状是可行的。

Using Tracer Stick to Measure Smoke Flow Region in Model Underground Oil Depot

It is great significance to study the smoke slow of fire to know the occurrence and development of the fire of the single underground tunnel whose early form is burning and the fire deepens on burning after banging. The fire experiment has been made on the model underground oil depot. The region of smoke flow of the fire has been measured by making use of tracer tick. The phenomenon of dividing areas has been analyzed in this paper . It is shown by the research of smoke flow and layering in smoke flow area and inert movement area that the means of measuring the height of smoke layer and qualitatively revealing the flow shape and properties by making use of tracer stick is viable.
