ABSTRACT
An experimental investigation of influence of various inhibitors (CF3H, C2F5H, C3F7H, C3F6H2, CF2ClH, C2F5Cl, C2F5I, C4F8, C4FI0, C2F4Br2, Inh A1) on combustion characteristics of hydrogen - air and methane - air mixtures in closed vessel has been carried out. Flammability limits, maximum explosion pressure, maximum pressure rise rate have been determined. An effect of chemical induction has been revealed, when combustion of lean hydrogen - air and methane - air mixtures promotes oxidation of fluorinated halons with an appropriate elevation of maximum explosion pressure and maximum pressure rise rate. It has been found, that inhibitor Inh A1, proposed by Institute of Structural Macrokinetics of Russian Acdemy of Sciences, influences on upper flammability limit of hydrogen in air more strong in comparison with diluents investigated in this work (except C2F5I). This phenomenon allows to concider Inh A1 as a perspective substitution of halons for explosion prevention of hydrogen - air mixtures.
