Laminar flame speeds and oxidation kinetics of tetrachloromethane

摘要: The laminar flame speeds of blends tetrachloromethane (CCl 4 ) with methane in air at room temperature and atmospheric pressure were experimentally determined using the counterflow twin-flame technique, varying both amount CCl fuel equivalence ratio unburned mixture. Flame measured for stoichiometric mixtures -to-CH ratios between 0 0.429 by volume ranges 0.7–1.3 0.7–1.2 0.053 0.200, respectively. Comparison present experimental results previous data CH 3 Cl-, 2 Cl -, CHCl -CH -air flames demonstrates dominant influence atomic Cl-to-H on propagation rate chlorinated addition. A detailed kinetic model previously employed Cl, , combustion was expanded to include additional pathways pertinent combustion. Numerical simulation shows that this predicts reasonably well. Carbon flux sensitivity analyses indicate oxidation kinetics doped are essentially same as those other chloromethanes.
