| 摘 要： | 对新型生物秸秆不燃板材搭建的活动板房进行了全尺寸火灾试验.通过测量板房室内外的温度数据及室外不同距离处的热辐射强度数据,分析生物秸秆不燃板房的火灾蔓延特性.通过回归分析建立生物秸秆不燃板房的室外最大热辐射强度与距离的函数关系式,确定生物秸秆不燃板房的安全防火间距.结果表明,秸秆防火板材的阻燃性能对于抑制火灾蔓延有重要作用;采用生物秸秆不燃材料的活动板房,临栋的安全防火间距建议为2.34m;对于极端大风天气,生物秸秆不燃板房临栋的安全防火间距建议为2.51m.

| Abstract: | Full-scale fire experiments were conducted to study the fire safety distance of novel straw fireproofing houses. Room temperatures, ambient temperatures and thermal radiation intensities were measured to analyze the behavior of straw fireproofing houses during the fire. The formula for the maximum outdoor thermal radiation intensities of straw fireproofing house at various distances was obtained by regression analysis, and this equation could be used to calculate the fire safety distance. It is found that the fire spread is significantly restricted by using straw fireproofing material. For the straw fireproofing houses, the fire safety distance is suggested to be 2.34 m. Furthermore, for the straw fireproofing houses under severe weather conditions with strong wind, the fire safety distance is suggested to be 2.51 m. |
