US4231302A — Apparatus and process for burning of fuels of rel…

Claim 1

Independent Claim 203 words

A heating assembly for burning fuel of organic origin, comprising, in combination: a substantially enclosed hollow assembly including a predetermined region within said assembly for receiving the fuel for ignition purposes; first oxygen supply means for supplying said predetermined region with oxygen at least at a rate adequate for producing a gas flow of distilled-off gases, air gases and combustion gases from the ignited fuel; an elongated outer shell disposed within said predetermined region and having a plurality of passages for dividing said gas flow into a plurality of streamlets; an elongated inner shell, having an inlet and an outlet, disposed within said outer shell and defining a space between said inner and outer shells, said space communicating with said inlet, said streamlets being recombined into a gas stream in said space; second oxygen supply means for supplying said inner shell with oxygen near its inlet for burning said stream of gas; and an exhaust conduit communicating with said outlet for exhausting said burnt stream from said heating assembly, whereby said stream of gas remains in said heating assembly for a predetermined dwelling time, said predetermined dwelling time being substantially proportional to the sum of the lengths of said inner and outer shells.

Claim 2

Dependent Claim 203 words

A heating assembly for burning fuel of organic origin, comprising, in combination: a substantially enclosed hollow assembly including a predetermined region within said assembly for receiving the fuel for ignition purposes; first oxygen supply means for supplying said predetermined region with oxygen at least at a rate adequate for producing a gas flow of distilled-off gases, air gases and combustion gases from the ignited fuel; an elongated outer shell disposed within said predetermined region and having a plurality of passages for dividing said gas flow into a plurality of streamlets; an elongated inner shell, having an inlet and an outlet, disposed within said outer shell and defining a space between said inner and outer shells, said space communicating with said inlet, said streamlets being recombined into a gas stream in said space; second oxygen supply means for supplying said inner shell with oxygen near its inlet for burning said stream of gas; and an exhaust conduit communicating with said outlet for exhausting said burnt stream from said heating assembly, whereby said stream of gas remains in said heating assembly for a predetermined dwelling time, said predetermined dwelling time being substantially proportional to the sum of the lengths of said inner and outer shells.

Claim 3

Dependent Claim 25 words

A heating assembly as claimed in claim 1 wherein said inner and outer shells are elongated cylinders defining an elongated annular space between said shells.

Claim 4

Dependent Claim 18 words

A heating assembly as claimed in claim 1 wherein said second oxygen supply means includes a venturi tube.

Claim 5

Dependent Claim 18 words

A heating assembly as claimed in claim 1 wherein said first and second oxygen supply means are adjustable.

Claim 6

Dependent Claim 44 words

A heating assembly as claimed in claim 1 wherein said second oxygen supply means includes at least one perforated guidewall surrounding said inlet of said inner shell for guiding the oxygen into said inner shell, said stream of gas passing easily through said perforations.

Claim 7

Dependent Claim 36 words

A heating assembly as claimed in claim 1 further including a catalytic burner, and wherein said exhaust conduit is followed by, and communicates with said catalytic burner for after-burning combustible matter contained in said gas stream.

Claim 8

Dependent Claim 43 words

A heating asembly as claimed in claim 1, wherein said first oxygen supply means supplies oxygen substantially at a predetermined direction, and wherein said inner and outer shells are substantially transverse with respect to said predetermined direction of said first oxygen supply means.

Claim 9

Dependent Claim 30 words

A heating assembly as claimed in claim 1 wherein said second oxygen supply means supplies oxygen at least adequate for complete combustion of the combustible matter in said gas stream.

Claim 10

Dependent Claim 50 words

A heating assembly as claimed in claim 1, further comprising a plurality of walls at least partly surrounding said predetermined region, at least one of said walls having at least one nozzle-like passage communicating with said first oxygen supply means for supplying oxygen through said passage to said predetermined region.

Claim 11

Dependent Claim 53 words

A heating assembly as claimed in claim 9, wherein at least one of said walls has two sets of nozzle-like passages, said first set being positioned vertically above the second set, and each passage of said first set having a cross-sectional area at least as large as each passage of said second set.

Claim 12

Dependent Claim 33 words

A process for treating fuel of organic origin in a heating assembly including first and second regions proximate to one another, the steps comprising in combination: placing the fuel in said first region;

Claim 13

Dependent Claim 33 words

A process for treating fuel of organic origin in a heating assembly including first and second regions proximate to one another, the steps comprising in combination: placing the fuel in said first region;

Claim 14

Dependent Claim 133 words

igniting the fuel; simultaneously supplying the fuel with first quantities of oxygen at least at a rate required for degassing and gasification, and at most at a rate required for partial combustion of the fuel thereby producing a gas flow containing distilled off gases, air gases and combustion gases; separating said gas flow into a plurality of streamlets; simultaneously segregating said streamlets from the fuel; thereafter recombining said streamlets into a gas stream; enveloping said second region with said gas stream; supplying oxygen to said second region at a rate at least adequate for burning said gas stream; simultaneously exhausting said burnt gas stream from said second region thereby creating suction at least adequate for drawing said gas stream into said second region; and simultaneously circulating said gas stream around said second region.

Claim 15

Dependent Claim 133 words

igniting the fuel; simultaneously supplying the fuel with first quantities of oxygen at least at a rate required for degassing and gasification, and at most at a rate required for partial combustion of the fuel thereby producing a gas flow containing distilled off gases, air gases and combustion gases; separating said gas flow into a plurality of streamlets; simultaneously segregating said streamlets from the fuel; thereafter recombining said streamlets into a gas stream; enveloping said second region with said gas stream; supplying oxygen to said second region at a rate at least adequate for burning said gas stream; simultaneously exhausting said burnt gas stream from said second region thereby creating suction at least adequate for drawing said gas stream into said second region; and simultaneously circulating said gas stream around said second region.

Claim 16

Dependent Claim 21 words

A process for treating fuel as claimed in claim 11 further comprising the step of catalytically afterburning the exhausted gas stream.

Claim 17

Dependent Claim 24 words

A process for treating fuel as claimed in claim 11 wherein the steps of supplying oxygen to said first and second regions are controllable.

Claim 18

Dependent Claim 29 words

A process for treating fuel as claimed in claim 11 further comprising the step of removing a portion of said gas stream from said heating assembly for independent utilization.
