A Study on the Smoldering hazard of Rice bran dust.
쌀겨 분진의 훈소 위험성에 관한 연구
Abstract
We intended to investigate combustion properties of rice bran dust. Combustion properties of h rice bran dust according to size distribution and amount were measured as temperature v variation with time using spontaneous ignition apparatus. Moreover, combustion properties w with blowing or without blowing condition were checked in order to investigate combustion p properties in spontaneous ignition apparatus according to flow condition of air. A As the mass and size of rice bran dust was increased, i띠ti외 smoldering temperature was l lowered. All of combustion forms were smoldering combustion. Initial smold얹ing temperature w was slightly lower with blowing condition than without blowing condition in spontaneous i ignition apparatus, which condition made heating value high.
쌀겨분진의 훈소위험성을 조사하기 위하여 자연발화 시험기를 이용하여 시료의 입도분포 및 시료량에 따른 쌀겨분진의 연소특성을 시간에 따른 온도의 변화로 측정하였다. 또한 자연발화 시험기 내부의 공기흐름에 따른 연소특성을 조사하고자 자연발화시험기 내부를 송풍과 무풍 상태로 하여 연소상태를 관찰하였다. 연구결과, 쌀겨분진의 연소에 따른 발열개시온도는 약 18
