On the Combustion of Chlorinated HydrocarbonsI. Trichloroethylene

摘要

Premixed flames of highly chlorinated hydrocarbons (CHCs), such as trichloroethylene, possess two widely separated flame zones at I atm. In the first zone, the CHCs undergo fast oxidative decomposition reactions, with the formation of mainly CO, HCI and Cl2, as the principal intermediate combustion products, followed by the HCl and Cl2, inhibited, slow combustion of CO, which finally leads to the establishment of the second flame zone. The extent of flame zone separation depends on the degree of dilution present, as well as the chlorine content of the system. A global and a semi-detailed chemical kinetic model of C2HCl3and CO oxidation are presented to explain the observed flame zone characteristics of chlorinated hydrocarbons
