Study on the influence of placement mode on the vertical upward flame spread of corrugated paperboard
In order to study the influence of the change of corrugated cardboard arrangement on fire spread,the double-layer corrugated cardboard is selected as an experimental sample to analyze the difference of its com-bustion characteristics under different arrangement and channel direction.The results show that the outer layer of corrugated cardboard will show obvious flame layering phenomenon during the fire spreading process,and the change of flame height with time shows a power function relationship.The change of the arrangement has less influence on the fire spread in the vertical direction of the channel and more influence on the fire spread in the horizontal direction of the channel;in the process of changing the direction of the cardboard channel,there is a certain difference in the influence of the heat transfer process on the fire spread in the internal channel.The results of this paper help to better grasp the influence of corrugated cardboard placement on combustion characteristics,and have a certain guiding effect on the optimization and design of corrugated cardboard box structures as well as the prevention and control of fires in warehousing places.
