Comparative spectroscopic study inside turbulent flames of diesel and waste cooking oil using hyper-spectral camera

Abstract

The excitations of molecules due to reactions inside turbulent flames are very complicated to study. In this research, investigation on the intensity of the reaction rates inside and around flames of light diesel oil (LDO) and waste cooking oil (WCO) blends with light and heavy diesel fuel (HDO) using Hyper-spectral camera of wide range of measurements at various fuel/air equivalence ratios. The addition of waste cooking oil to both LDO will achieve fuel saving in which results of peak emissions at fuel/air equivalence ratio (Ф) = 0.96 and Ф = 1.1 are equal at all zones of reactions. But, addition of WCO to HDO make the combustion process tends to lean mixtures where peak emissions values at Ф = 0.75, 0.96 and 1.1 are equal at the last three zones of reaction.
