Abstract
Abstract A fuel supply system is disclosed in which oil and water are mixed and delivered under pressure to a nozzle or other atomizing means at which combustion is to occur. The mixture of oil and water is delivered to the atomizing means along conduit means and those conduit means include means to produce agitation of the oil and water so that an intimate mixture of oil and water is delivered to the atomizing means. Complete emulsification occurs at the atomizing means to promote combustion.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
169 words
A fuel supply system comprising a pump and nozzle means, a source of fuel, a source of water, first conduit means through which a mixture of fuel and water is delivered to said pump, means establishing liquid flow communication from said fuel source and water source to said first conduit means at at least one location spaced from said pump, second conduit means through which the fuel and water mixture is delivered from said pump to said nozzle means, and means disposed within said second conduit means for agitating said fuel and water flowing within said second conduit means from said pump to said nozzle whereby an intimate mixture of fuel and water is delivered to said nozzle where final emulsification takes place, said means for agitating said fuel and water in said second conduit means, said pump and said nozzle constituting means for emulsifying the fuel and water, said pump comprising pressure means for supplying pressure in said first and second conduit means and through said agitating means.
Claim 2
Dependent Claim
169 words
A fuel supply system comprising a pump and nozzle means, a source of fuel, a source of water, first conduit means through which a mixture of fuel and water is delivered to said pump, means establishing liquid flow communication from said fuel source and water source to said first conduit means at at least one location spaced from said pump, second conduit means through which the fuel and water mixture is delivered from said pump to said nozzle means, and means disposed within said second conduit means for agitating said fuel and water flowing within said second conduit means from said pump to said nozzle whereby an intimate mixture of fuel and water is delivered to said nozzle where final emulsification takes place, said means for agitating said fuel and water in said second conduit means, said pump and said nozzle constituting means for emulsifying the fuel and water, said pump comprising pressure means for supplying pressure in said first and second conduit means and through said agitating means.
Claim 3
Dependent Claim
43 words
The system as claimed in claim 1 further comprising means disposed within said first conduit for agitating said fuel and water flowing within said first conduit upstream of said pump, whereby an intimate mixture of fuel and water is delivered to said pump.
Claim 4
Dependent Claim
21 words
A system as claimed in claim 1 wherein said means for causing agitation comprise baffle means disposed within said conduit means.
Claim 5
Dependent Claim
13 words
A system as claimed in claim 3 wherein said baffle means are static.
Claim 6
Dependent Claim
23 words
A system as claimed in claim 4 wherein said baffle means are effective to produce a swirling motion of said fuel and water.
Claim 7
Dependent Claim
27 words
A system as claimed in claim 5 wherein said baffle means comprises an insert disposed in said conduit means and including a plurality of blade like projections.
Claim 8
Dependent Claim
20 words
A system as claimed in claim 5 wherein said baffle means comprises a helical spring disposed within said conduit means.
Claim 9
Dependent Claim
23 words
A system as claimed in claim 5 wherein said baffle means comprises rifling grooves formed in the interior surface of said conduit means.
Claim 10
Dependent Claim
37 words
The fuel system of claim 1 further comprising condenser means for condensing water from the products of burning said fuel and water emulsion to be mixed with said fuel in the first conduit upstream of said pump.
