摘　　要：The disperse phase (water) droplet size of Emulsified Heavy-Oil (EHO) has a significant effect on the Combustion of Water-in-Heavy oil Emulsion. In this paper, the disperse degree of disperse phase in EHO is measured in various experimental conditions, and the relationship of the disperse degree with the agitating degree is investigated. The following results are obtained: with the increases of agitating speed, agitating time and agitator diameter, disperse degree become better. The experimental results show that the disperse degree becomes much better when n is 1*#200r/min and D m is 55mm. The D SV of disperse phase in EHO will decrease as the increasing of agitating speed and agitator diameter, which is consistent with the energy theory. Then according to dimensional analysis, an experimental formula to calculate the surface area of water particle per unit volume is given. 5 figs. 4tabs. 9refs.The disperse phase (water) droplet size of Emulsified Heavy-Oil (EHO) has a significant effect on the Combustion of Water-in-Heavy oil Emulsion.
