Decomposition of chlorine and (or) fluorine-bearing substances in a gas mixture ignited by a slipping surface discharge

Experimental investigation of decomposition of chlorofluorocarbons (CF2Cl2, CF4), as well as SiCl4 and SiF4 contained in an oxygen-hydrogen gaseous mi xture, combustion of which is initiated by a high-current pulse slipping su rface discharge, has been carried out. It was found that a ternary gaseous mixture of oxygen+hydrogen+chlorine- an d (or) fluorine-bearing gas, even with a large amount of the third componen t, maintains the explosion combustion property inherent in a binary hydroge n-oxygen mixture, 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 slipp ing surface discharge combustion propagation behaviour has some peculiariti es that are beyond the ordinary combustion wave or detonation wave mechanis ms. Peculiarities of the observed phenomena may be attributed to the strong UV irradiated by a high-current slipping surface discharge.
