摘　　要：堆积固体自燃火灾是常见多发火灾,由于其规模庞大、着火延迟期长等特点,难以进行全尺寸的模拟实验,为火灾预防和调查工作带来了一定的难度。基于F-K(Frank-Kamenetskii)理论,将小规模实验结果外推,从而预测或判断一定尺寸的堆积固体在一定的环境温度下自燃起火的危险性。Tile spontaneous fire ignition in bulk solids occurs frequently. This kind of fire ignition has the characters of large - scale and long induction period, so it is difficult to protect and investigate. Based on Frank - Kamenetskii theory, a given geometry of material may be determined experimentally. The experimental conclusion may be used to predict spontaneous ignition behaviour outside the range by extrapolation.
