Depletion of Fuel Aromatic Components and formation of Aromatic Species in a Spray Flame as characterized by Fluorescence spectroscopy

摘要

In-flame sampling followed by chemical and spectroscopic analysis coupled with laser-induced fluorescence (LIF) measurements excited in the UV region (266 nm) were performed on a spray combustion system burning a diesel oil and a vegetable aromatic-free fuel like a rapeseed oil. A large florescence emission peaked in the UV was found in the spray region of the diesel oil flame attributed to the unburned aromatic species of the fuel.
