Water-in-oil type emulsion fuel oil

Abstract

A water-in-oil type emulsion fuel oil is prepared by dispersing and emulsifying in heavy oil a water/carbon mixture prepared by dispersing carbon fine particles in water with a dispersant and a protective colloid. The emulsion fuel oil includes 100 vol % of heavy oil and 20 to 45 vol % of the water/carbon mixture. Water particles are uniformly dispersed and emulsified in the heavy oil in the form of particles having diameters exceeding 20 μm but not exceeding 35 μm, and when the amount of the water/carbon mixture to be mixed with 100 vol % of the heavy oil is 20 to 35 vol %, the dispersed water particles have diameters ranging from 25 to 35 μm, while when the amount is 35 to 45 vol %, they have diameters of from more than 20 μm to 25 μm. Because, in this emulsified fuel oil, flame temperature does not change in comparison with the heavy oil combustion to which water is not add, this emulsified fuel oil is extremely advantageous in view of a heat balance. Since oil to be combusted is decreased, CO2 to be exhausted is decreased, thereby it is effective in inhibiting global warming.
