COMBUSTIBLE LIQUIDS SUPPRESSION WITH HIGH-BOILING HALONS

The current research considers the model of combustible liquids suppression with halon in order to detect the most appropriate conditions for fire-extinguishing process. It offers a material balance equation of halon supplied to suppress combustible liquids. It also demonstrates that the more halon is consumed and the smaller is the burning zone height, the faster fire-extinguishing composition reaches fire-extinguishing concentration. The burning zone height depends on mass consumption of halon, the drops of which eject air out from the environment into the burning zone. As a part of research, the fire-extinguishing process was optimized. There is shown that the minimal specific consumption equals optimal supply rate of halon in the article. It also provides efficiency indexes of combustible liquids suppression
