However, as soot concentration increases to a point where soot is emitted from the flame, rapid reactions between soot particle and OH. result in concentration levels close to equilibrium values. These results clearly demonstrate that soot particles are far from passive species in flames and can directly affect the chemical pathways involved in the oxidation process through radioactive effects on temperature and soot particle reactivity effects on radical concentrations. The CO and smoke yields were observed for underventilated laminar diffusion flames burning methane and ethene for global equivalence ratio over the range 0.5 to 4.0. A Burke-Schumann type burner with fuel in the center tube and air in the annular region was used. The peak CO yields for methane and ethene, 0.37 and 0.47 respectively, are at least a factor of 100 greater than for overventilated burning.
