| 摘 要： | 在自行研制的火灾可燃物热解和着火早期特性试验台上,针对建筑装潢中常用的木材进行了热解和着火特性试验,试验的辐射热流选择20～70 kW/m2,试验结果表明,水分对木材的热解和着火特性影响很大,相同辐射热流下,随着含水率的增加,木材的着火时间延长;辐射热流强度对木材的热解和着火也有很大影响,随着外加辐射热流的增加,木材着火时间逐渐缩短。

| Abstract: | Experiments on pyrolysis and ignition of wet woods,widely used in the buildings,were carried out on the apparatus for investigating pyrolysis and ignition of combustible materials.Slab-shaped samples of wood（the area is 100 mm×100 mm and 15 mm thick） were subjected to different heat fluxes ranging from 20 kW/m2 to 70 kW/m2.Experimental results indicated that moisture content had strongly effect on pyrolysis and ignition of wood;The increasing moisture content increased the time for spontaneous ignition at the given intensity of radiation.The increasing intensity heat flux decreased the time to ignition. |

| Keywords: | radiant heat flux moisture content wood pyrolysis and ignition |
