The minimum energies required to initiate the combustion of gaseous tetrafluoroerthy1ene (TFE) and mixtures thereof with nitrogen, argon, and helium at various initial pressures and temperatures are determined. Flame transition from the gas to the liquid phase of TFE is investigated. Liquid TFE is demonstrated to be virtually nondetonable. The fuel-lean flammability and detonability limits of TFE-air mixtures under normal conditions are demonstrated to be identical, 12.2 vol %. © 2014 Pleiades Publishing, Ltd. Source

The flammability limits for combustible gas (methane, hydrogen)-nitrous oxide-fluorinated hydrocarbon (trifluoromethane CHF3, pentafluoroethane C2HF5, perfluorobutane C 4F10) mixtures are experimentally determined. The upper and lower flammability limits turned out to be, respectively, significantly higher and lower as compared to those characteristic of the combustion in air. The compositions of the mixtures at the peaks of the flammability curves are characterized by lower values of the fuel equivalence ratio φ (in most cases, φ < 0.1) as compared to the combustion in air and in a 25 vol % oxygen-nitrogen medium (typically φ > 0.5). It was established that the inhibiting concentrations of fluorinated hydrocarbons for the combustion of methane and hydrogen in nitrous oxide are similar, in contrast to the combustion in oxygen- nitrogen oxidative media. A qualitative interpretation of the results is given. © 2014 Pleiades Publishing, Ltd. Source

Kinetic aspects of controlling ignition and flame propagation parameters in the gas phase by chemical methods are considered. The efficiency of the chemical methods is due to the branched chain character of gas-phase combustion reactions and the dominant role of the competition between chain branching and chain termination in these processes. © 2011 Pleiades Publishing, Ltd.
