Abstract

Accidents of dust explosion has been occurred in various industries as a plastics, pharmaceuticals, timber, grain storage, solid fuels and chemicals. In this study, the silo dust, hammer mill dust and Nyusong dust in the manufacturing process of the particle board to utilize west wood, which were selected for this experiment and were evaluated the characteristics of dust explosion. The explosion characteristics such as a maximum explosion pressure, explosion index, lower explosive limit, and minimum ignition energy in suspended dust of the wood by Siwek 20 L apparatus were measured and evaluated for the experiment. The results of this study can be used the process safety measures to prevent accidents of fire and explosion in the suspended dust of wood.

분진폭발은 플라스틱류, 제약, 목재, 곡물 저장고, 고체연료 및 화학약품의 제조와 같은 다양한 산업에서 발생되고 있다. 본 연구에서는 폐목재를 재활용하여 Particle board를 생산하는 공정의 사이로 분진, 함머밀 분진 및 뉴송 분진을 선택하여 분진폭발 특성을 평가하였다. 실험은 20 L 구형 폭발용기를 이용하여 목재 부유분진의 최대폭발압력, 분진폭발지수, 폭발한하계, 및 최소 점화에너지를 측정하고, 평가하였다. 이들 연구결과는 Particle board를 생산하는 제조공정의 화재 폭발사고 예방을 위한 공정안전 정보로 활용할 수 있을 것이다.
