FIELD: oil and gas industry.
SUBSTANCE: emulsion fuel in which average diameter of water or fuel material is 1000 nm or less (average diameter of 200 to 700 nm is more preferable) is obtained by fine grinding and mixing of water with combustible oil product by means of finely grinding and mixing device at addition of 10.0 to 150.0 volume parts of water for 100 volume parts of combustible oil product. At that, the used water preferably has reducing potential - 100 mV or less and more preferably 300 mV or less.
EFFECT: good stability, high combustion efficiency and high energy-saving effect.
