Using wood pellets, which are used as fuel for thermal power generation plants, as test specimens, the minimum spontaneous ignition temperatures according to the size of the container for the test specimens were measured, and by applying the Frank-Kamenetskii theories on thermal energy to these temperatures, the danger factor of the materials were calculated by deriving the apparent activation energies. The results confirmed that the ignition threshold temperature decreased as the size of the container increased and that the spontaneous ignition energy was 37.83 kcal/mol. The results also confirmed that the larger the container for the test specimens was the time to arrive at the spontaneous ignition time and maximum temperature also increased.
