Abstract
The present study aims to draw a complete characterization of glycerol-heavy fuel oil emulsions by a novel non-invasive and fast investigation technique, which helps to determine emulsion stability and physico-chemical properties through acoustic measurements application. The reflection of ultrasonic wave on emulsion droplets, particles size and volume allows analysis of phase acoustic characters, which proved good correlation with Turbiscan, especially regarding stability and structural integrity. Further combustion tests revealed a decrease in pollutants emissions proportional to glycerol fraction addition. Moreover, NO wasn't detected in combustion gas. In order to overcome toxic acrolein atmospheric release, the combustion chamber was heated to 700 degrees C with diesel oil.
