Abstract:
Extinction conditions for diffusion flames of gases and vapors in various media were studied experimentally. The limiting blowout velocities of a diffusion jet when heated Í$_2$ – N$_2$ and Í$_2$ – Í$_2$Î mixtures flow out into air were found. The minimum fire-extinguishing concentrations upon diffusion combustion of gases (ÑÍ$_4$ and Ñ$_3$Í$_8$) and liquids (A-76 gasoline) were measured.
