On basket heating methods for obtaining exothermic reactivity of solid materials : The extent and impact of the departure of the crossing-point temperature from the oven temperature

摘要: T his paper reports that the crossing-point temperature (CPT), where heat conduction diminishes at centre of a symmetrical exothermically reactive solid (or an assembly packed particles), can be considerably different from set oven during transient basket heating procedure for measuring exothermic reactivity. The CPT differs by larger amount greater and is also dependent upon sample size nature materials concerned. experimental evidence such differences, derived various previous studies, illustrated here. Such differences can, under certain circumstances, lead to considerable variations in estimation kinetic parameters two existing testing procedures. This important point consideration future work area thermal ignition particulate materials.
