The Effect of Strain Rate and the Chemical Effects of H2 and CO on the Soot Formation of Ethylene-Syngas in Opposed Jet Laminar Diffusion Flame

In this work, the effects of the composition of the syngas, the deformation rate and the chemical effect of H2 and CO on the internal structure of the flame as well as the soot formation, in a laminar diffusion flame of a syngas mixture / ethylene. The configuration has two opposite jets and is used at an interval of the ignition deformation rate at extinction under atmospheric pressure. Chemistry in the gas phase is coupled according to the soot model based on polycyclic aromatic hydrocarbons (PAH), by the moment's method. The insertion of the inactive species FH2 and FCO will also be included to determine the chemical effect of H2 and CO. The results have shown that the increase in hydrogen in the syngas leads to a decrease in the growth rates of the soot in dilution effect as well as by chemical effects due to the abolition of the abstraction reaction of H in the hydrogen -addition hydrogen abstraction sequence of C2H2.
