The ripple flame arrester is a safety device used to prevent the spread of flames from flammable gases and liquids and to prevent backfires that could lead to explosions. It is typically installed on storage tanks and pipelines that transport or discharge flammable and explosive gases, such as flares, heating and combustion systems, petroleum gas recovery systems, or other flammable gas systems.
Currently, metal mesh filters are widely used in flame arresters, with numerous metal meshes arranged inside the cylinder to absorb heat. This is because metal is a good conductor of heat, thereby blocking one of the three essential elements for combustion: the heat required for combustion. The three essential elements for combustion are combustible materials, oxidizers, and the heat required for combustion. Due to the absorption of a large amount of heat, even if the first two factors are present, the combustible materials cannot reach the temperature required for combustion (spontaneous combustion) due to insufficient heat, naturally preventing the combustion process from continuing and forcing it to terminate. Simply put, the fire extinguishing principle of a flame arrester is that when a flame passes through narrow pores, the cooling effect causes a sudden increase in heat loss, thereby terminating the combustion. Factors affecting the performance of a flame arrester include the thickness of the flame arresting layer and the size of its pores or channels.
