Abstract

Non-combustible solid materials play a major role as inerting agents in explosion prevention. While the importance and application of these materials are well understood, there is still a lack of information about the actual mechanisms responsible for explosion suppression. Especially, the role of inert materials with a large specific surface area and the influence of the moisture content of inert materials have not been sufficiently investigated. In this work, an experimental and computational study of the effects of inert materials on ignition and flame propagation in lycopodium–air mixtures is undertaken. The influence of a large specific surface area is studied by using Clinoptilolith as an inert material.

惰性颗粒添加剂对粉尘-空气混合物中点火和火焰传播的影响

摘要

不可燃固体材料在防爆中起惰化剂的作用。尽管这些材料的重要性和应用已广为人知，但仍缺乏有关负责爆炸抑制的实际机制的信息。特别是，尚未充分研究具有大的比表面积的惰性材料的作用和惰性材料的水分含量的影响。在这项工作中，进行了实验和计算研究，研究了惰性材料对石蒜空气混合物中点火和火焰传播的影响。通过使用斜发石作为惰性材料研究了大比表面积的影响。
