Abstract
In this study, we measured soot and NO_x in a cyclone-jet combustor. A laser induced incandescence (LII) technique was applied to obtain instantaneous soot concentration. As for NO_x emission, premixed and non-premixed combustion were examined with changing equivalence ratio. Results show that, when the air volume rate is increased, EINO_x in non-premixed combustion is reduced to the level of premixed combustion. The soot is not detected when the equivalence ratio is less than 2.
