Abstract
Abstract An incinerator system is provided with a rotary incinerating chamber, a burner for directing flame into the chamber, feed means at one end of the chamber, an exhaust conduit for removing combustion gases from chamber, a secondary combustion chamber connected to the conduit for receiving exhaust gas therefrom and an exhaust stack connected to the downstream end of the secondary chamber. The rotary incinerating chamber is provided with a frustoconical interior surface with the feed end being the smaller diameter end thereof, said incinerator chamber being mounted for rotation about a horizontal axis of rotation for imparting abrasive tumbling movement to waste material feed to said one end by said feed means. The burner is mounted at the feed end for initiating immediate incineration of said waste material and means are provided at the end opposite said one end for removing the solid incinerated material therefrom. The secondary combustion chamber includes a burner mounted for tangential flame discharge at an angle to longitudinal axis of the chamber to provide a cyclonic aspirating gas flow through the conduit from the incinerating chamber. The combustion chamber may be of modular construction.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
130 words
In an incinerator unit, a rotary incinerating chamber, a burner for directing flame into said chamber, feed means at one end of the chamber and an exhaust conduit at the opposite end of said chamber for removing combustion gases therefrom, said combustion chamber including at least one chamber section provided with a generally cylindrical exterior surface and a frustoconical interior surface with said one end being the smaller diameter end thereof, said chamber being mounted for rotation about a horizontal axis of rotation for imparting abrasive tumbling movement to waste material feed to said one end by said feed means, said burner being mounted at said one end for initiating immediate incineration of said waste material, said unit including means at said opposite end for removing solid incinerated material therefrom.
Claim 2
Dependent Claim
130 words
In an incinerator unit, a rotary incinerating chamber, a burner for directing flame into said chamber, feed means at one end of the chamber and an exhaust conduit at the opposite end of said chamber for removing combustion gases therefrom, said combustion chamber including at least one chamber section provided with a generally cylindrical exterior surface and a frustoconical interior surface with said one end being the smaller diameter end thereof, said chamber being mounted for rotation about a horizontal axis of rotation for imparting abrasive tumbling movement to waste material feed to said one end by said feed means, said burner being mounted at said one end for initiating immediate incineration of said waste material, said unit including means at said opposite end for removing solid incinerated material therefrom.
Claim 3
Dependent Claim
39 words
The incinerator of claim 1 wherein the feed means and the burner are radially offset from the horizontal axis of rotation of said incinerating chamber and the exhaust conduit is positioned adjacent said opposite end of said combustion chamber.
Claim 4
Dependent Claim
141 words
In an incinerator unit, a rotary incinerating chamber, a burner for direction flame into said chamber, feed means at one end of the chamber and an exhaust conduit at the opposite end of said chamber for removing combustion gases therefrom, said combustion chamber being provided with a frustoconical interior surface with said one end being the smaller diameter end thereof, said chamber being mounted for rotation about a horizontal axis of rotation for imparting abrasive tumbling movement to waste material feed to said one end by said feed means, said burner being mounted at said one end for initiating immediate incineration of said waste material, said unit including a secondary combustion chamber connected to the conduit for receiving exhaust gas therefrom, said secondary combustion chamber being provided with gas flow control means adapted to provide a cyclonic aspirating gas flow therethrough.
Claim 5
Dependent Claim
141 words
In an incinerator unit, a rotary incinerating chamber, a burner for direction flame into said chamber, feed means at one end of the chamber and an exhaust conduit at the opposite end of said chamber for removing combustion gases therefrom, said combustion chamber being provided with a frustoconical interior surface with said one end being the smaller diameter end thereof, said chamber being mounted for rotation about a horizontal axis of rotation for imparting abrasive tumbling movement to waste material feed to said one end by said feed means, said burner being mounted at said one end for initiating immediate incineration of said waste material, said unit including a secondary combustion chamber connected to the conduit for receiving exhaust gas therefrom, said secondary combustion chamber being provided with gas flow control means adapted to provide a cyclonic aspirating gas flow therethrough.
Claim 6
Dependent Claim
38 words
The incinerator of claim 3 wherein the secondary chamber is cylindrical and the gas flow control means includes a burner mounted for tangential flame discharge at an acute angle to the longitudinal axis of said cylindrical secondary chamber.
Claim 7
Dependent Claim
18 words
The incinerator of claim 1 wherein said incinerating chamber is comprised of a plurality of modular chamber sections.
Claim 8
Dependent Claim
20 words
The incinerator of claim 5 wherein said modular sections provide a continuous frustoconical configuration throughout the interior of said chamber.
Claim 9
Dependent Claim
46 words
The incinerator of claim 1 wherein said feed means includes a feed chute positioned predominantly to one side of the incinerating chamber''s axis of rotation and the burner is radially spaced from the axis of rotation and on the opposite side thereof from the feed chute.
Claim 10
Dependent Claim
20 words
The incinerator of claim 1 wherein said combustion chamber slopes from said one end at an angle of about 2*-3*.
Claim 11
Dependent Claim
156 words
In an incinerator unit, an elongated rotary incinerating chamber having an enlarged discharge end for gas exhaust and ash discharge, a burner positioned at the end of the chamber opposite said enlarged discharge end for directing flame into said chamber generally toward said discharge end, a plurality of supports spaced along said chamber for supporting said chamber for rotation about a horizontal axis, and drive means including a horizontal drive shaft for rotatably driving said chamber on said supports, said chamber including at least one longitudinally extending chamber section having an interior chamber wall of frustoconical configuration, said chamber being rotated by said drive means about the longitudinal axis of said frustoconical wall, said longitudinal axis being coincident with said horizontal axis of rotation to substantially eliminate all thrust bearing loads acting on said horizontal drive shaft and said supports while promoting natural flow of the exhaust gas and ash discharge toward said enlarged discharge end.
