Self-heating and Spontaneous Ignition of Fibreboard Insulating Panels

摘要

In recent years, several fires in Canada have been attributed to spontaneous ignition in insulating fibreboard panels. To investigate this claim, critical temperatures for the spontaneous ignition of 75, 190 and 305 mm cubes of fibreboard were measured in small-scale laboratory tests. Employing the Frank-Kamenetskii theory, it was then theory, it was then determined that the critical temperature for spontaneous ignition of a 1.2 m cubical pallet of fibreboard is 104 ∞ C and for a tractor trailer full of fibreboard is 89 ∞C.
