Improved combustion efficiency is achieved by separately preparing a water-in-oil emulsion, containing up to about 90 volume % water, and blending the emulsion into an oil fuel prior to combustion. The blended oil fuel contains from 1 to about 10 vol. % water in the form of tiny droplets having a diameter within the range from about 1 to about 10 microns. The process of this invention may be applied to heating systems, steam boilers, gas turbines, rotary kilns, and internal combustion engines, including diesel engines.

A process for the improved combustion of oil fuels in a combustion zone, comprising the steps of: (a) preparing a water-in-oil emulsion in a combustible oil carrier fluid, said water-in-oil emulsion containing from about 20 to about 90 volume % water present as droplets having a diameter within the

A process for the improved combustion of oil fuels in a combustion zone, comprising the steps of: (a) preparing a water-in-oil emulsion in a combustible oil carrier fluid, said water-in-oil emulsion containing from about 20 to about 90 volume % water present as droplets having a diameter within the range from about 1 to about 10 microns; (b) thereafter blending the water-in-oil emulsion into the fuel in a proportion selected to provide a water content dispersed in the fuel within the range from about 2 to about 10 volume %; and (c) introducing the blended fuel to the combustion zone. Apparatus, for the improved preparation of water-in-oil emulsions for use in the combustion of oil fuels in a combustion zone, said emulsions containing water droplets having an average diameter within the range from about 1 to about 10 microns, comprising: (a) an emulsification vessel, affording means for the preparation of a water-in-oil emulsion; (b) separate metered lines for feeding, respectively water, combustible oil carrier fluid, and emulsification additive to the emulsification vessel; (c) an emulsion holding tank; (d) cycling means for the circulation of water-in-oil emulsion between the emulsification vessel and the emulsion holding tank; (e) an oil fuel blending zone; (f) first delivery means, for the metered delivery of the water-in-oil emulsion to the oil fuel blending zone; and (g) second delivery means, for the transfer of blended emulsion and oil fuel from the blending zone to the combustion zone, or optionally, to an intermediate storage zone.
