The combustion behavior of single fuel droplets of water-in-'A' heavy oil emulsions was observed in an electric furnace in order to elucidate the dominant factor for the occurrence of microexplosions. The tests were carried out by changing the following parameters : the size of water droplets in the emulsified fuels having the same water content, the ratio of water to 'A' heavy oil, and the power of surfactants in the emulsions. The results reveal that it is not the ratio of water to 'A' heavy oil, but the size of water droplets in the emulsified fuels which plays the most important role in microexplosions and surfactants my be the factor disturbing the occurrence of microexplosions by the effect of stabilizing the emulsified fuels. These phenomena are very similar to 'The Vaporizing Behavior of the Oil Droplet of Water-in-Oil Emulsions on the Hot Surface' reported previously by the authors.
