Abstract
Abstract A cyclone separator in which an outer cylinder is formed by a plurality of vertically-extending, spaced, parallel tubes and extends around an inner pipe in a coaxial relationship therewith to define an annular chamber. A portion of the tubes forming the outer cylinder are bent out of the plane of the cylinder to form an inlet opening in a tangential relationship to the annular chamber for receiving gases containing solid particles and directing same through the annular chamber for separating the solid particles from the gas by centrifugal forces. The tubes are bent radially inwardly towards the inner pipe to support the inner cylinder and water is passed through the tubes to cool the outer cylinder.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
153 words
A cyclone separator comprising an inner cylinder; an outer cylinder extending around said inner cylinder in a coaxial relationship to define an annular chamber between the two cylinders, said outer cylinder comprising a plurality of tubes extending vertically and circumferentially in a parallel relationship for at least a portion of their lengths, a portion of said tubes being bent from the plane of said outer cylinder to form an inlet opening in a tangential relationship to said outer cylinder for receiving gases containing solid particles and directing same through said annular chamber for separating the solid particles from said gases by centrifugal forces, the separated gases exiting through said inner cylinder and the separated solids falling to the bottom of said outer cylinder for disposal, said tubes being bent radially inwardly towards said inner cylinder to support said inner cylinder; and means for passing water-steam through said tubes to cool said outer cylinder.
Claim 2
Dependent Claim
153 words
A cyclone separator comprising an inner cylinder; an outer cylinder extending around said inner cylinder in a coaxial relationship to define an annular chamber between the two cylinders, said outer cylinder comprising a plurality of tubes extending vertically and circumferentially in a parallel relationship for at least a portion of their lengths, a portion of said tubes being bent from the plane of said outer cylinder to form an inlet opening in a tangential relationship to said outer cylinder for receiving gases containing solid particles and directing same through said annular chamber for separating the solid particles from said gases by centrifugal forces, the separated gases exiting through said inner cylinder and the separated solids falling to the bottom of said outer cylinder for disposal, said tubes being bent radially inwardly towards said inner cylinder to support said inner cylinder; and means for passing water-steam through said tubes to cool said outer cylinder.
Claim 3
Dependent Claim
25 words
The separator of claim 1 wherein upper portions of said tubes are bent across the upper end of said outer cylinder to form a roof.
Claim 4
Dependent Claim
38 words
The separator of claim 1 wherein upper and lower end portions of said tubes are configured to form two opposite side walls of an enclosure and the intermediate portion of said tubes are bent into said cylindrical configuration.
Claim 5
Dependent Claim
24 words
The separator of claim 1 further comprising a plurality of support tubes connected to said outer cylinder for supporting said separator from a building.
Claim 6
Dependent Claim
14 words
The separator of claim 1 wherein said tubes are disposed in a spaced relationship.
Claim 7
Dependent Claim
24 words
The separator of claim 5 wherein each tube has a continuous fin extending from diametrically opposite portions thereof for the length of said tube.
Claim 8
Dependent Claim
20 words
The separator of claim 5 further comprising refractory means extending around the inner and outer surfaces of said outer cylinder.
