中文摘要: |
本文叙述了在15-32KW/㎡辐射条件下对四种木材点燃性的研究,测定了木材(64×64×18mm)水平方向着火点(点燃状态形成)时的木材表面温度及点燃时间。结果表明:辐射强度等于或高于24KW/㎡时,可以较准确地测量木材的点燃温度,且此温度基本保持一致(±20℃)。辐射强度较低时,木材表观点燃温度大大高于辐射强度较高时的点燃温度,本文对这一现象进行了讨论。 |
英文摘要: |
The experimental investigation about the ignition temperature of four species of wood,under radiant heat fluxes of 15~32kw/㎡is described,the surface temparature and time of ignition of horizontal samples(64×64×18mm)at the firepoint are measured.These data show that the ignition temperature could be measured more precisely when the heat fluxes is not lower that 24kw/㎡,and these temperatures could not shifted over ±20℃ generally.The phehomenon that the apparent firepoint temperature when the heat fluxes are not more than 24kw/㎡is much higher than that when the heat fluxes are larger is also discussed. |
