Heavy oil emulsion fuel composition

摘要

A heavy oil emulsion fuel composition which contains heavy oils, such as bitumen and asphalt, wherein the heavy oil emulsion fuel composition can be used as a substitute fuel for heavy fuel oils, and has an enhanced combustion efficiency to thereby reduce the content of soot, dust and nitrogen oxides after combustion, which comprises (a) 40 to 85% by weight of a heavy oil, (b) 10 to 40% by weight of water, (c) 0.1 to 5% by weight of a surfactant and (d) at least 0.1% by weight of at least one component selected from the group consisting of water-soluble compounds having in its molecule two or more hydroxyl groups, monohydric alcohols having 6 or more carbon atoms, and mixtures thereof.
