The features of gaseous mixtures combustion initiated by high current slipping surface discharge
Experimental investigation of decomposition of chlorofluorocarbons (CFCs) contained in an H2+O2 or CH4+O2 gaseous mixtures, combustion of which is initiated by high-current pulse slipping surface discharge, has been carried out. It was found that a ternary gaseous mixture of H2+O2+CFC or CH4+O2+CFC even with a large amount of the third component, maintains the explosion combustion property inherent in a binary H2+O2 or CH4+O2 mixtures, based on the branched chain processes. High-efficient (near complete) destruction of chlorine-fluorine containing substances has been demonstrated. Combustion dynamics was investigated. It was shown that initiation by slipping surface discharge combustion propagation behavior has some peculiarities that are beyond the ordinary combustion wave or detonation wave mechanisms. Peculiarities of the observed phenomena may be attributed to the strong UV irradiated by a high-current slipping surface discharge.
