A reduced kinetic mechanism for premixed CH3Cl/air flames

A reduced chemical kinetic mechanism is developed in order to predict the flame phenomena associated with methyl chloride burning in air. The reduced mechanism, which consists of nine global steps, is systematically derived from a detailed scheme involving 63 elementary steps. The reduced mechanism is capable of explicitly calculating the concentration of 15 species along the C1 and C2 pathways (including molecular nitrogen, which acts as an inert), and implicitly predicting the concentration of ten species. Good agreement is found between the flame speeds predicted by the detailed and reduced mechanisms, and with experimental results obtained in this laboratory. In addition, the species concentration profiles obtained by the reduced mechanism are in agreement with those predicted by the detailed mechanism. The reduced mechanism derived in the present study has been investigated for premixed flames burning stoichiometric mixtures of methyl chloride and air, and its application should be limited to the same.
