“…As with the forest materials examined previously, the critical condition is unequivocal. Figure 2 shows results for RM plotted according to Equation (1) and the line yields a value of 73 kJ mol-' for the overall activation energy. Table 2 lists the values for all of the samples, and the Frank-Kamenetskii plots are shown for all of the samples in Figure 3.…”

“…where q = exothermicity c = heat capacity Materials used in this part of the program contain typically 45% by weight of water, in contrast to the litters examined previously [1][2][3][4] which had equilibrated with atmospheric moisture and contained approximately 15% moisture. The litter samples were estimated as having a q value of 17 MJ kg-1, and scaling this for 45% moisture gives approximately 11 MJ kg-I as the exothermicity of the solid part of the leaves.…”

“…Material values of 202°C for a 9-cm cube 27 and 176°C for an 8-cm cube 29 have been measured which are higher than the 137°C spontaneous ignition temperature of sawdust determined by Anthony and Greaney 24 for compacted cubes with 61-cm sides. The determination of the isothermal activation energies (E g ), which are responsible for the additional energies that must be transferred by an ignition source, beyond that to bring the combustible to temperature, typically involve a systematic series of experiments with ground and compacted specimens that are uniformly heated in an oven.…”
