摘要:
An oil-in-water type heavy oil emulsion fuel having a specific and broad particle size distribution which has a viscosity close to that of water, can be sufficiently atomized at a temperature of room temperature to 90.degree. C., is excellent in the handleability and fluidity, despite a very high heavy oil concentration, and has a very excellent stability such that neither precipitation nor increase in the viscosity occurs even after storage for a long period of time is prepared according to the present invention. Oil-in-water type heavy oil emulsion fuel according to the present invention can be used as a substitute fuel for heavy fuel oil without modification of the boilers. Further, the combustion efficiency of the heavy oil emulsion fuel according to the present invention is high and it is possible to reduce the amount of nitrogen oxides and sulfur oxides after combustion.
