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 stability of emulsified heavy oil(EHO) has a significant effect on the combustion of water in heavy oil emulsion Based on the prior experimental studies, the influential factors are studied systematically before/after magnetization in various experimental conditions It is found that the stability of EHO is related to fuel type, the percentage of water added in oil(PWA) , Emulsifier added in oil(PEA),magnetic strength and the tube material The following results are obtained: the stability of EHO decreases as the increase of PWA and the decrease of PEA before/after magnetization; in the same experimental conditions, the stability of EHO becomes better after magnetization, when PWA varies in the range from 7 5% to 12 5% and, PEA being bigger than 0 03%, there is a better stability; No 100,No 200 and CL 1 oil has the different stability, the order is No 100>No 200>CL 1; the higher the magnetic strength, the better the stability of EHO; in view of energy consumption and the stability, the rational value of magnetic strength is from 1?200?GS to 1?400?GS; using stainless steel tube has a better effect on stability than using iron
