Abstract
The paper gives results of a study of the ignition process of liquid fuel droplets and its impact on the formation of soot and nitrogen oxides (NOx). The system studied consists of a laboratory flame maintained by a vertical, monosized liquid fuel droplet array surrounded by a laminar flow of a mixture of helium and oxygen. It was found that the formation of soot and NOx closely correlated with the ignition of liquid fuel droplets. It has been shown that the soot formation can be suppressed by delaying ignition, and thus vaporizing as much fuel as possible prior to the ignition. But delaying ignition favors the conversion of fuel-bound nitrogen to nitric oxide (NO). The control of the emission of both soot and NOx can be achieved by use of low oxygen concentrations in the oxidation gas to delay ignition and suppress soot formation by using a high fuel/air ratio to reduce NOx.
