RESEARCH OF SUBSTRATE PARAMETERS GRANULATED FOAM GLASS INFLUENCING THE EVAPORATION OF FLAMMABLE LIQUIDS
The article presents the results of a study of the geometric parameters of a granular foam glass substrate. A diagram and description of the process of maintaining the combustion of a liquid in a tank is presented, as well as the effect of a granular foam glass substrate on the extinguishing of a flame of a combustible liquid. The equivalent diameter of the channels of the granular substrate of foam glass fraction 5-7 mm and the average equivalent diameter of the channel affecting the extinguishing of the flame in capillary-porous media was evaluated. The average equivalent diameter of the channel was experimentally determined, and the average channel cross-sectional area (the area of evaporation of a combustible liquid) in the granular layer was estimated. The dependences of the evaporation rate of flammable liquids (AI-92 gasoline, n-hexane, kerosene, diesel fuel, ethanol) on the height of the granular support layer, as well as the dynamics of the level rise of the wetted glass foam granules during spill, are established.
