AU - Eades, Robert AU - Perry, Kyle PY - 2019 DA - 2019/09/02 TI - Evaluation of a 38 L Explosive Chamber for Testing Coal Dust Explosibility SP - 5810173 VL - 2019 AB - Coal dust explosions are the deadliest disasters facing the coal mining industry. Research has been conducted globally on this topic for decades. The first explosibility tests in the United States were performed by the Bureau of Mines using a 20 L chamber. This serves as the basis for all standardized tests used for combustible dusts. The purpose of this paper is to investigate the use of a new 38 L chamber for testing coal dust explosions. The 38 L chamber features design modifications to model the unique conditions present in an underground coal mine when compared to other industries where combustible dust hazards are present. A series of explosibility tests were conducted within the explosive chamber using a sample of Pittsburgh pulverized coal dust and a five kJ Sobbe igniter. Analysis to find the maximum pressure ratio and ķ ST对于每个试验,进行可燃性粉尘参数。基于这种分析,观测用于与所述爆炸性测试是否被下为燃料或过燃料的每个浓度制备。基于此分析,为未来的爆炸性测试浓度的建议作出。SN - 2090年至1968年UR - https://doi.org/10.1155/2019/5810173 DO - 10.1155 /五百八十一万○一百七十三分之二千○一十九JF - [燃烧的PB - Hindawi出版KW - ER -
