Continuity of kinetics between sub- and supercritical regimes in the oxidation of a high-volatile solid substrate

Feat samples were subjected to oven experiments spanning a considerable temperature range, some resulting in ignition and some in failure to ignite. Heat release rates for the two display a temperature dependence describable by a single pair of Arrhenius parameters in spite of significantly greater volatiles release in some experiments than in others. Applicability of the Frank-Kamenetskii treatment to such materials is discussed in the light of these findings. Copyright (C) 1996 Elsevier Science Ltd.
