Evaporation and combustion characteristics of a single aqueous glycerin solution droplet suspended in an electric furnace were investigated as a fundamental study for spray combustion of glycerin. The furnace temperature was changed between 280℃ to 900℃. Diameter of suspended droplet was around 2.6mm. Effects of furnace temperature and glycerin concentration on evaporation and combustion rate constants were investigated experimentally. Moreover, the viscosity of aqueous glycerin solution was measured to discuss its atomization characteristics. It was shown that the evaporation and combustion rate constant of glycerin solution droplet decreased with increasing the water content in glycerin solution and the rate of 90wt% glycerin droplet was similar to that of JIS C heavy fuel oil. As for the viscosity of aqueous glycerin solution, the value of 90wt% glycerin was much lower than that of JIS C heavy fuel oil. From these results, 90wt% glycerin solution was probably used as substitution for JIS C heavy fuel oil.
