Abstract
Abstract An integrated incinerator and heat exchanger unit of modular construction capable in conjunction with other units or alone of efficiently removing pollutents carried by the exhaust gas flow of an industrial system. The unit comprises a boxlike enclosure having a series of internal flues each containing a static, heat exchange, packed bed of particulate material and being in flow communication with the other flues of a unit through a common chamber, the chamber including one or more burners for heating the beds, each unit having a common inlet duct and a common outlet duct with flow control means therein to permit predetermined entry and exit of flow into and out of respective flues, the unit being capable of burning out trapped solids in the heated beds by means of temporary isolation of their respective flues, and the unit including a self-limiting ambient air entry for each flue to purge its bed and improve incineration efficiency.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
63 words
The apparatus set forth in claim 1 wherein a plurality of enclosures are juxtaposed and joined together by structural means, and adjacent ends of the inlet conduit means of respective enclosures are joined in flow communicative relation and the adjacent ends of the outlet conduit means of the enclosures are joined in flow communicative relationship to form common inlet and outlet conduit means.
Claim 2
Dependent Claim
75 words
The apparatus set forth in claim 1 wherein said apparatus includes means for intermittently reducing flow into and out of any of said flues, said heating means is adapted to elevate the temperature of said heat exchange means, and said flow reducing means in conjunction with said heating means burn out material trapped in said heat exchange means by heating said heat exchange means in said any flue while reducing flow in said any flue.
Claim 3
Dependent Claim
68 words
The apparatus set forth in claim 3 wherein duct means is connected between said any flue and said inlet conduit means, and said duct means includes means for governing flow between said any flue and said inlet conduit means to permit removal of the gaseous products of the burning out of the material trapped in the heat exchange means of said any flue from said heat exchange means.
Claim 4
Dependent Claim
42 words
The apparatus set forth in claim 1 wherein each of said passage means has an opening communicating between the interior thereof and ambient, and means for closing said opening to govern the flow of ambient into said passage means through said opening.
Claim 5
Dependent Claim
36 words
The apparatus set forth in claim 5 wherein said closing means precludes flow of ambient through said opening only said valve means permits flow between said passage means having said opening and Said outlet conduit means.
Claim 6
Dependent Claim
168 words
Apparatus for continuous, thermal regenerative processing of gas flow comprising an enclosure having at least three flues therein, heat exchange means in said flues, inlet and outlet conduit means adapted, respectively to transfer flow to be processed and exhaust processed flow, passage means in flow communication with each of said at least three flues and with said inlet and outlet conduit means, a chamber within said enclosure communicating with each of said plurality of flues and containing heating means adapted to elevate the temperature of said heat exchange means, means controlling flow in said passage means, said flow passing from said inlet conduit means through said passage means and one of said at least three flues into said chamber across said heating means and exiting said chamber to said outlet conduit means through another flue and passage means, and said flow controlling means in conjunction with said heating means burning out material trapped in the heat exchange means by heating said heat exchange means while reducing flow therein.
Claim 7
Dependent Claim
65 words
The apparatus set forth in claim 7 wherein duct means is connected between each of said passage means and said inlet conduit means, said duct means including means for governing flow between said passage means and said inlet conduit means to permit removal of the gaseous products of the burning out of the material trapped in the heat exchange means from the heat exchange means.
Claim 8
Dependent Claim
189 words
Apparatus for continuous, thermal regenerative, processing of gas flow comprising an enclosure having at least three flues therein, heat exchange means in said flues, inlet and outlet conduit means adapted, respectively, to transfer flow to be processed and exhaust processed flow, passage means in flow communication with each of said plurality of flues and with said inlet and outlet conduit means, a chamber within said enclosure communicating with each of said plurality of flues and containing heating means, means for controlling gas flow in said passage means, said passage means having an opening communicating between the interior thereof and ambient means for closing said opening to govern the flow of ambient into said passage means, said flow passing from said inlet conduit means through said passage means and one of said at least three flues into said chamber across said heating means and exiting said chamber to said outlet conduit means through another flue and passage means, and said closing means precluding flow of ambient through said opening only when said gas flow controlling means permits flow between said passage means having said opening and said outlet conduit means.
Claim 9
Dependent Claim
131 words
A process for continuous, thermal regenerative, gas purification in apparatus comprising an enclosure having heating means and at least three flues with heat exchange means therein, inlet and outlet conduit means, passage means in flow communication with each of said at least three flues and said inlet and outlet conduit means, and means for controlling flow in said passage means, comprising the steps of reducing the flow only in the passage means communicating with a flue having heat exchange means experiencing increased flow resistance due to trapped material therein carried by the flow, heating the heat exchange means of said flue communicating with said passage means at reduced flow to an elevated temperature, and removing the gaseous products of the burning out of said trapped material from said heat exchange means.
Claim 10
Dependent Claim
53 words
The process set forth in claim 10 further comprising the steps of connecting duct means between said passage means and said inlet conduit means, controlling flow in said duct means and permitting return of the gaseous products upon removal from said heat exchange means to said inlet conduit means through said duct means.
Claim 11
Dependent Claim
152 words
A process for continuous, thermal regenerative, gas purification in apparatus comprising an enclosure having at least three flues with heat exchange means therein, inlet and outlet Conduit means, passage means in flow communication with each of said at least three flues and said inlet and outlet conduit means, and means for controlling gas flow in said passage means, comprising the steps of normally maintaining the passage means open to ambient flow, purging the passage means and heat exchange means in flow communication with said passage means of entrapped gases with ambient flow into said passage means and said heat exchange means only when said controlling means precludes gas flow between said passage means and said inlet conduit means and said passage means and said outlet conduit means, and closing said passage means to ambient flow only when said controlling means permits gas flow between said passage means and said outlet conduit means.
