On the basis of the experimental study of the various factors affecting the viscosity ,stability and disperse phase(water)droplet size of emulsified heavy-oil(EHO),according to the combustion effect evaluation of EHO before or after adding water in it and the analysis of various factors affecting the Percentage of Water Added in Oil(PWA),a kind of optimization measure of PWA is designed in this paper. The practice in tunnel furnace which combusts heavy oil, shows that: (1) The effect of energy-saving and environmental prevention can be evaluated by means of calculating the oil-saving rate and measuring the concentration of NO x , CO or smut. (2) When the EHO is combusted, the decreasing of needed air in the course of combustion will lead to the better effect of oil-saving. (3) The practical application example demonstrates that the experimental results have a good significance on how to use this energy-saving technology successfully. 4figs.,2tabs., 10refs.
