Abstract

In this work the evaporation of the emulsified glycerol- heavy fuel oil (CG-HFO) droplets with different activator is modeled. The influence of activator gas bubbles volume developments on the evaporation of fuel droplets in the high temperature combustion chamber is studied. The crude glycerol as the secondary product of biodiesel production is used as the first component of the emulsion while the second component is heavy fuel oil. The crude glycerol contains methanol, aromatics, minerals, a little bit biodiesel and water. These materials were pressurized and injected in the chamber with three inputs: the first one is for the CG-HFO, the second one is for activator while the third one is for air for forming the emulsion and then passing to the combustion chamber. The applied pressure is determined according to contents which lead to flame stability of the primary formed emulation. A comparison of calculated results, basing on semi-empirical method, with experimental ones demonstrates the modeling acceptable accuracy.
