Abstract
Abstract A method of and apparatus for incinerating a wide range of solid waste materials in a smokeless, odorless manner, Solid wastes are contained within a combustion chamber in a whirling, driving, vortical, rotating envelope of air that is present in an excess of that theoretically required to burn the waste. A combustible fuel is burned within the chamber. The particulates resulting from the combustion of the waste materials are suspended within the resulting burning cyclone of air and fuel, burned, and the effluent vented from the combustion chamber. Preferably, an afterburner is used to burn any lighter weight particulate matter that may escape from the combustion chamber.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
106 words
Apparatus for disposing of solid waste comprising a combustion chamber having a closed circular wall and adapted to receive the solid waste to be disposed, a burner carried by said wall and positioned to direct its discharge into the combustion chamber, and a series of airports stationed axially of said wall and adapted to direct air inside the combustion chamber and peripherally around the closed circular wall to form a driving, vortical, rotating envelope for entrapping and supporting the waste to be burned, the discharge of said airports chemically supporting combustion of burnable waste within said envelope, said combustion chamber having a vent to release effluent.
Claim 2
Dependent Claim
106 words
Apparatus for disposing of solid waste comprising a combustion chamber having a closed circular wall and adapted to receive the solid waste to be disposed, a burner carried by said wall and positioned to direct its discharge into the combustion chamber, and a series of airports stationed axially of said wall and adapted to direct air inside the combustion chamber and peripherally around the closed circular wall to form a driving, vortical, rotating envelope for entrapping and supporting the waste to be burned, the discharge of said airports chemically supporting combustion of burnable waste within said envelope, said combustion chamber having a vent to release effluent.
Claim 3
Dependent Claim
13 words
Apparatus according to claim 1 in which said air ports have jet nozzles.
Claim 4
Dependent Claim
26 words
Apparatus according to claim 1 in which said vent is an opening having an axis eccentric with respect to the longitudinal axis of the combustion chamber.
Claim 5
Dependent Claim
47 words
Apparatus according to claim 1 in which said combustion chamber has a charging door for entry of said solid waste, and said air ports are stationed adjacent said door to provide a seal thereover by means of the air discharge directed peripherally along the closed circular wall.
Claim 6
Dependent Claim
28 words
Apparatus according to claim 1 in which said burner is stationed in the circular wall remote from said vent, and said airports are intermediate said burner and vent.
Claim 7
Dependent Claim
29 words
Apparatus according to claim 1 in which said vent connects to a second combustion chamber having a burner adapted to burn any combustible matter escaping the first combustion chamber.
Claim 8
Dependent Claim
60 words
Apparatus according to claim 6 in which said vent enters said second combustion chamber through an entrance port, the burner of the second combustion chamber is directed substantially across said entrance port, and a baffle plate extends over the burner and past said port to aid in reducing the velocity of the effluent and subsequent removal therefrom of particulate matter.
Claim 9
Dependent Claim
24 words
Apparatus according to claim 7 in which said baffle plate is essentially tunnellike and defines an open-ended enclosure covering said burner and entrance port.
Claim 10
Dependent Claim
88 words
Apparatus according to claim 1 in which the vent is an opening stationed offcenter with respect to the longitudinal axis of said first-mentioned combustion chamber, and said vent connects to a second combustion chamber having a burner adapted to burn any combustible matter escaping the first combustion chamber, the relative volumes of the second combustion chamber and vent being such as to reduce substantially the velocity of such effluent in passing from the first combustion chamber to the second combustion chamber to aid in removing therefrom particulate matter.
Claim 11
Dependent Claim
50 words
Apparatus according to claim 1 in which a second series of airports is mounted in said closed circular wall of the combustion chamber diametrically opposite the first-mentioned series of airports, the two series of airports being adapted to direct their discharge in the same direction peripherally around the circular wall.
Claim 12
Dependent Claim
19 words
Apparatus according to claim 1 in which said closed circular wall of the combustion chamber is substantially vertically disposed.
Claim 13
Independent Claim
91 words
A method of incinerating solid waste within a combustion chamber, comprising admitting a combustible fuel into said combustion chamber, discharging a plurality of airstreams into said combustion chamber in substantial parallelism to form a driving, vortical, rotating envelope, introducing solid waste into said envelope, suspending and confining the particulates within the envelope and away from sides of the combustion chamber by means of the rotation of the envelope, burning said waste in said envelope while chemically supporting its combustion by said air, and venting the resulting effluent from the combustion chamber.
Claim 14
Independent Claim
91 words
A method of incinerating solid waste within a combustion chamber, comprising admitting a combustible fuel into said combustion chamber, discharging a plurality of airstreams into said combustion chamber in substantial parallelism to form a driving, vortical, rotating envelope, introducing solid waste into said envelope, suspending and confining the particulates within the envelope and away from sides of the combustion chamber by means of the rotation of the envelope, burning said waste in said envelope while chemically supporting its combustion by said air, and venting the resulting effluent from the combustion chamber.
Claim 15
Dependent Claim
27 words
A method according to claim 12 in which the air supplied is at least 50 percent more than that theoretically required for complete combustion of said waste.
Claim 16
Dependent Claim
12 words
A method according to claim 12 in which said fuel is gas.
Claim 17
Dependent Claim
21 words
A method according to claim 12 including venting said effluent from the combustion chamber eccentrically with respect to its longitudinal axis.
Claim 18
Dependent Claim
52 words
A method according to claim 12 in which said combustible fuel is discharged into the combustion chamber at a point remote from that at which the effluent is vented, and said plurality of airstreams is discharged into the combustion chamber at points intermediate the discharge of the fuel and point of venting.
Claim 19
Dependent Claim
26 words
A method according to claim 12 including passing said effluent into a second combustion chamber and burning therein any combustible matter escaping the first-mentioned combustion chamber.
Claim 20
Dependent Claim
37 words
A method according to claim 17 including baffling the flow of the effluent from the first to the second combustion chamber to aid in reducing the velocity of the effluent and subsequent removal therefrom of particulate matter.
Claim 21
Dependent Claim
39 words
A method according to claim 17 in which passing said effluent into a second combustion chamber includes passing the effluent into a chamber of sufficiently enlarged volume as to reduce its velocity and aid in removing therefrom particulate matter.
