On the Soot Concentration Profile and Method of Soot Control in the Spray Jet Flames

(Effect of Water Jet)

Abstract

The research is started with the object of finding the factors that influence soot formation by the temperature reduction in the flame, when added water is changed under the condition of the fixed spray quantity of kerosine, flame shape and size.
It observe how soot concentration is governed by the low temperature reactions arising from atomized water, and at the same time measured the temperature distribution and the concentration of various gas species, to jet fuel (kerosine) from the inner tube and water from the outside tube respectively and make a jet burner with air.
Finally, the suppression of soot formation occurs mainly in the region of the nozzle neighborhood, suggesting that low temperature pyrolysis reactions are the dominating reason.
