Abstract
Abstract A feed unit for a fuel burner has first and second conduit means for supplying liquid hydrocarbon and an emulsifying liquid, for example water, to a premixing chamber from which the premixture is conducted to a mixing chamber in which there is an injection nozzle with an opening through which a jet of the emulsion is emitted and causes a member located in the path of the jet to be vibrated so as to emulsify the emulsion.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
138 words
A feed unit for fuel burners, for the supply of an emulsion of a liquid in a liquid hydrocarbon to a burner, said unit comprising a. a casing, b. a premixing chamber in the casing, c. first conduit means in the casing for conducting liquid hydrocarbon to the chamber, d. second conduit means in said casing for conducting an emulsifying liquid to the chamber, e. a plate adjacent the premixing chamber, having passages therein, f. a mixing chamber into which a premixture of liquid hydrocarbon and emulsifying liquid is conducted from the premixing chamber by the passages in said plate, g. an injection nozzle in said mixing chamber having an injection opening, and h. a vibratory member located opposite said injection opening in the path of a jet of premixture issuing from said opening, for emulsifying the premixture.
Claim 2
Dependent Claim
138 words
A feed unit for fuel burners, for the supply of an emulsion of a liquid in a liquid hydrocarbon to a burner, said unit comprising a. a casing, b. a premixing chamber in the casing, c. first conduit means in the casing for conducting liquid hydrocarbon to the chamber, d. second conduit means in said casing for conducting an emulsifying liquid to the chamber, e. a plate adjacent the premixing chamber, having passages therein, f. a mixing chamber into which a premixture of liquid hydrocarbon and emulsifying liquid is conducted from the premixing chamber by the passages in said plate, g. an injection nozzle in said mixing chamber having an injection opening, and h. a vibratory member located opposite said injection opening in the path of a jet of premixture issuing from said opening, for emulsifying the premixture.
Claim 3
Dependent Claim
31 words
A feed unit as defined in claim 1, wherein said first and second conduit means merge upstream of the premixing chamber into a single conduit means discharging into said premixing chamber.
Claim 4
Dependent Claim
32 words
A feed unit as defined in claim 1, wherein the passages in said plate converge in a downstream direction at an angle of substantially 45* to a plane perpendicular to the plate.
Claim 5
Dependent Claim
17 words
A feed unit as defined in claim 1, wherein said vibratory member comprises a thin, flat blade.
Claim 6
Dependent Claim
22 words
A feed unit as defined in claim 4, further comprising means for adjusting the distance between said blade and said injection opening.
Claim 7
Dependent Claim
22 words
A feed unIt as defined in claim 4, wherein the longitudinal median planes of said blade and said injection opening are coincident.
Claim 8
Dependent Claim
25 words
A feed unit as defined in claim 6, wherein the longitudinal median planes of said blade and said injection opening are parallel and spaced transversely.
Claim 9
Dependent Claim
42 words
A feed unit as defined in claim 4, wherein each of said plate, injection nozzle and vibratory blade is calibrated to a particular flow of liquid hydrocarbon, whereby each may be replaced by one of different calibration to provide the desired flow.
Claim 10
Dependent Claim
22 words
A feed unit as claimed in claim 4 wherein said injection opening is in the form of a slit facing said blade.
Claim 11
Dependent Claim
22 words
A feed unit as claimed in claim 1 further comprising means to produce a vortex stream of the premixture in said nozzle.
