Abstract
An experimental study of the effect of additives of trifluoroiodomethane (CF3I) - one of the most effective combustion inhibitors that are safe for both humans and the environment - on the shock-initiated ignition in multicomponent combustible mixtures, namely syngas (mixture of hydrogen, CO, and methane) and mine gas (mixture of methane and acetylene). The addition of CF3I strongly inhibits the ignition of syngas and affects the ignition of mine gas only slightly. Kinetic modeling has been carried out, and a kinetic mechanism describing the observed regularities has been proposed.
