Abstract

Abstract A combustion process in which a water-in-oil emulsion of liquid fuel, such as liquid hydrocarbons, containing from 10 to 50% water and preferably 10 to 30% water is burned. The emulsion is produced, with little or no added emulsifying agent, by sonic agitation, including a sonic generator and an acoustic transformer having a larger cross-section coupled to or in contact with the sonic generator than at its other end, at which emulsification takes place, whereby the sonic energy density is increased. With the increased sonic density an emulsion is produced which when burned produces a quality of burn such that the combustion is faster, more complete, and cleaner, with an increase in efficiency even up to 30% of water. The increase in efficiency often equals that obtained by the burning of the same weight of pure fuel in the conventional manner.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 126 words
A process of burning liquid fuel comprising, in combination, generating sonic vibrations, amplifying the energy density thereof by acoustic transformation which distributes the sonic power over a reduced area providing a narrow restrictive zone at the point of amplifying sonic energy density, the restricted zone being between the end of the acoustic transformer, which effects the acoustic transformation, and a stationary element which acts as an anvil, introducing water and liquid fuel in a thin film in said restricted zone whereby the water and oil are subjected to the sonic vibration of amplified energy density and whereby a water-in-oil emulsion of fine particle size is produced, the water being in the range of 10% to 50% of the total fuel and water, and burning said emulsion.
Claim 2
Dependent Claim 126 words
A process of burning liquid fuel comprising, in combination, generating sonic vibrations, amplifying the energy density thereof by acoustic transformation which distributes the sonic power over a reduced area providing a narrow restrictive zone at the point of amplifying sonic energy density, the restricted zone being between the end of the acoustic transformer, which effects the acoustic transformation, and a stationary element which acts as an anvil, introducing water and liquid fuel in a thin film in said restricted zone whereby the water and oil are subjected to the sonic vibration of amplified energy density and whereby a water-in-oil emulsion of fine particle size is produced, the water being in the range of 10% to 50% of the total fuel and water, and burning said emulsion.
Claim 3
Dependent Claim 19 words
A process according to claim 1 in which the water content of the emulsion is from 10% to 30%.
Claim 4
Dependent Claim 26 words
A process according to claim 2 in which the emulsion is atomized and mixed with air and introduced into the cylinder of an internal combustion engine.
Claim 5
Dependent Claim 25 words
A process according to claim 1 in which the fuel and water emulsion produced is mixed with air, atomized, and burned in a heating burner.
Claim 6
Dependent Claim 25 words
A process according to claim 2 in which the fuel and water emulsion produced is mixed with air, atomized, and burned in a heating burner.
