Abstract

Abstract A fuel mixer and burner in which a disk with an open face is rapidly rotated within a loosely confining chamber rectangular in cross section and having aligned inlet and outlet openings. A blower delivers air at high volumes and velocities to the inlet opening of the chamber so that air flows parallel to the disk face, and fuel is directed perpendicularly against the disk face. For liquid fuels including heavy oils, the fuel is directed through a nozzle against a smooth disk face. For solid fuels, pieces of fuel are fed by an auger conveyor against a rough grinding surface on the disk. The fuel is particlized, thrown peripherally in all directions from the disk, intermixed thoroughly with air, and blown toward and through the chamber outlet opening. When ignited, the fuel-air mixture creates a flame formed about the disk that is directed out the outlet opening.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 121 words
A device for mixing fuel for burning comprising, in combination, a chamber having aligned inlet and outlet openings, a disk rotatably mounted in said chamber with a flat circular face in a plane that substantially bisects said openings, means for rapidly rotating said disk, a blower for delivering air at high speeds and volumes to said inlet opening, and means for directing, combustible fuel perpendicularly against said disk face so that the fuel is particlized, thrown in said plane peripherally in all directions from the disk, intermixed with air from said blower, and blown toward and through said outlet opening, whereby igniting the fuel-air mixture causes a flame to be formed around the disk that is directed out the outlet opening.
Claim 2
Independent Claim 121 words
A device for mixing fuel for burning comprising, in combination, a chamber having aligned inlet and outlet openings, a disk rotatably mounted in said chamber with a flat circular face in a plane that substantially bisects said openings, means for rapidly rotating said disk, a blower for delivering air at high speeds and volumes to said inlet opening, and means for directing, combustible fuel perpendicularly against said disk face so that the fuel is particlized, thrown in said plane peripherally in all directions from the disk, intermixed with air from said blower, and blown toward and through said outlet opening, whereby igniting the fuel-air mixture causes a flame to be formed around the disk that is directed out the outlet opening.
Claim 3
Dependent Claim 24 words
The combination of claim 1 in which said chamber is rectangular in cross section with the long dimension paralleling the face of said disk.
Claim 4
Dependent Claim 28 words
The combination of claim 1 in which said disk face is smooth, and said means for directing fuel includes a nozzle capable of discharging heavy viscous liquid fuel
Claim 5
Dependent Claim 53 words
The combination of claim 1 in which said disk face is roughened to define a grinding surface, and said means for directing fuel includes a mechanism for feeding pieces of solid fuel against said grinding surface, the feed rate of said mechanism being less than the potential grinding rate of said disk surface.
Claim 6
Dependent Claim 13 words
The combination of claim 4 in which said mechanism is an auger conveyor.
