固体可燃物易点燃性标准的探讨

可燃性固体的引燃和熄灭与辐射到其表面的临界热能量和产生挥发分所必需的表面温度有关。探讨固体可燃物易点燃性标准,燃怀标准,对防火和灭火在理论上有一定的指导意义。本文在理论分析的基础上,提出了一种用固体挥发分的临界质量通量量化解释引燃和熄灭条件的方法,给出了易点燃性的标准。

Discussion about the ignitibility of combustible solids

The ignition of a combustible solid and the extingushment of a burning solid is relevant to the critical heat flux from a flame and related to the surface temperature needed to produce volatile. Theoretically,discussion about the ignitibillity of a combustible solid is of a significance to guide fire protection and fire-fighting. This paper proposes a method to quantify the conditions of solid ignition and extinguishment with a critical mass flux of the volatile of a combustible solid. Finally,the "ignitibility" of the solid has been given.
