Experimental data on the combustion characteristics of methane-oxidative gas (O2 + N2)-inhibitor (CHF3, C2HF5, and C4F10) mixtures and an analysis thereof show that fluorinated hydrocarbons (HFC and FC) exhibit the properties of both flame inhibitors

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 H2−N2 and H2−H2O mixtures flow out into air were found. The minimum fire-e
