Determination of explosion parameters of hybrid mixtures

A common phenomenon that plays a leading role in ensuring fire and explosion safety of work with dust and gas mixtures is described: a hybrid mixture.Historical information is provided and the current state of the problem is defined.The necessity of studying such mixtures, as an example, for coal basins, is emphasized.The methods used in the world for determining the explosion parameters of hybrid mixturesthe maximum explosion pressure, the lower concentration limit of flame propagation, the minimum explosive oxygen content and the minimum phlegmatizing concentration of the phlegmatizer -are briefly considered.An experimental installation recommended for use in the Russian Federation is also considered in detail.The manufactured design of such an installation with the necessary additions is described.The results of experimental studies are presented, showing the need for further research and the possibilities of using such experimental installations in various fields of industry are described.
