Abstract
Abstract A fuel incineration system for a calciner wherein materials undergoing treatment therein evolve volatiles when subjected to a heat treatment and wherein some of these evolved volatiles and carbon particles entrained therein as well as carbon particulates entrained in fluid streams derived from quenching areas associated with the calciner are directed to an incinerator area intermediate the calciner and the flue stack and mixed with air and/or oxygen to combust some of these volatiles and carbon particulates in this area prior to their entry into the flue stack and any unburned volatiles and particulates escaping from the incinerator area are mixed with combustion air admitted at the lower portion of the flue stack to combust in the area of the stack so as to emit from the stack a gas essentially free of any combustible materials.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
124 words
A fuel incineration system for a calciner comprising heat treating volatile evolving materials within a substantially air tight enclosure having a flue stack for directing gases fed thereto from said enclosure into the atmosphere, a substantially air tight passageway for the feed of hot processed products from said enclosure to a substantially air tight quenching area, subjecting said processed products to a cooling operation while in said quenching area, a substantially air tight conduit extending from said quenching area to an incinerator area positioned intermediate the said enclosure and said flue, combusting in said incinerator area unburned volatiles and carbonaceous particulates emanating from said enclosure and from said quenching area to thereby exit from said flue a gas substantially free of any air contaminants.
Claim 2
Dependent Claim
124 words
A fuel incineration system for a calciner comprising heat treating volatile evolving materials within a substantially air tight enclosure having a flue stack for directing gases fed thereto from said enclosure into the atmosphere, a substantially air tight passageway for the feed of hot processed products from said enclosure to a substantially air tight quenching area, subjecting said processed products to a cooling operation while in said quenching area, a substantially air tight conduit extending from said quenching area to an incinerator area positioned intermediate the said enclosure and said flue, combusting in said incinerator area unburned volatiles and carbonaceous particulates emanating from said enclosure and from said quenching area to thereby exit from said flue a gas substantially free of any air contaminants.
Claim 3
Dependent Claim
21 words
The system recited in claim 1 wherein a plurality of quenching areas are provided for the cooling of the processed products.
Claim 4
Dependent Claim
31 words

Claim 5
Dependent Claim
24 words
The system recited in claim 1 wherein a blower is mounted in the conduit extending between the said quenching area and the said incinerator.
Claim 6
Dependent Claim
25 words
The system recited in claim 4 wherein a separator means is mounted in the conduit extending between the said quenching area and said incinerator area.
Claim 7
Dependent Claim
20 words

Claim 9
Dependent Claim
24 words
The system recited in claim 6 wherein air is admitted into the second incineration area to cool the uprising gases in said flue stack.
Claim 10
Independent Claim
223 words
An apparatus for combusting unburned carbonaceous materials entrained in a stream directed for exit through a flue stack for a furnace, comprising, a substantially air tight enclosure having a roof, side walls, and a hearth mounted for rotation within the said enclosure, means for feeding on said hearth materials capable of evolving volatiles when subjected to a heat treatment, subjecting said materials to a heat treatment while on said hearth, a passageway extending between said enclosure and said flue stack, an incineration area formed in said passageway and at the lower end of said flue stack, a conduit extending from said enclosure to a substantially air tight enclosure forming a quenching area for the materials fed thereinto from the said hearth, subjecting said processed materials to a cooling medium while in said quenching area, means for exhausting said cooling medium from said quenching area and directing the same to said incinerator areas through a substantially air tight conduit extending between said quenching area and said incinerator, air admitting ports extending into said incinerator areas for combusting unburned volatiles and carbonaceous particulates contained in said cooling medium as well as any unburned volatiles and carbonaceous particulates emanating from the materials undergoing treatment on the hearth to thereby exit through the outlet of said flue stack a gas substantially devoid of any air contaminants therein.
Claim 11
Independent Claim
223 words
An apparatus for combusting unburned carbonaceous materials entrained in a stream directed for exit through a flue stack for a furnace, comprising, a substantially air tight enclosure having a roof, side walls, and a hearth mounted for rotation within the said enclosure, means for feeding on said hearth materials capable of evolving volatiles when subjected to a heat treatment, subjecting said materials to a heat treatment while on said hearth, a passageway extending between said enclosure and said flue stack, an incineration area formed in said passageway and at the lower end of said flue stack, a conduit extending from said enclosure to a substantially air tight enclosure forming a quenching area for the materials fed thereinto from the said hearth, subjecting said processed materials to a cooling medium while in said quenching area, means for exhausting said cooling medium from said quenching area and directing the same to said incinerator areas through a substantially air tight conduit extending between said quenching area and said incinerator, air admitting ports extending into said incinerator areas for combusting unburned volatiles and carbonaceous particulates contained in said cooling medium as well as any unburned volatiles and carbonaceous particulates emanating from the materials undergoing treatment on the hearth to thereby exit through the outlet of said flue stack a gas substantially devoid of any air contaminants therein.
