Abstract
화력발전소의 연료로 사용되는 우드펠릿을 시료로 하여 시료 용기의 크기에 따른 최소자연발화온도를 구하였으며, 이 온도로부터 Frank-Kamenetskii의 열발화 이론을 이용하여 겉보기 활성화 에너지를 구함으로써 물질의 위험성을 예측하였다. 용기의 크기가 클수록 발화한계온도는 낮아졌으며, 겉보기 활성화 에너지는 37.83 kcal/mol을 구하였다. 또한 시료의 용기가 커질수록 발화유도시간 및 최고온도에 도달하는 시간이 길어졌다.
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.
