Abstract

A combustion/pyrolization system comprising a combustion/pyrolization chamber supported by the base frame, and a perforated grate forms a bottom surface of the combustion/pyrolization chamber and facilitates passage of char and boichar therethrough. The combustion/pyrolization chamber is open along at a top and an air manifold supplies a first source of combustion air across the top of the combustion/pyrolization chamber to form an air curtain. A char collection/transfer chamber is located below the perforated grate for collecting at least the char and boichar that passes therethrough, and a conveying mechanism transfers the char and boichar out of the combustion/pyrolization system for collection and use. An air plenum chamber cools the char collection/transfer chamber such that the supplied secondary air becomes heated, and the heated secondary air flows into the char collection/transfer chamber and through the perforated grate into the combustion/pyrolization chamber to provide secondary combustion air.

Claims (23)

1. A combustion/pyrolization system comprising:

a base frame;

a combustion/pyrolization chamber being supported by the base frame;

a perforated grate forming a bottom surface of the combustion/pyrolization chamber, and the perforated grate having a plurality of openings formed therein to facilitate passage of at least char and biochar therethrough;

the combustion/pyrolization chamber being open along at a top to facilitate feeding of feed material into the combustion/pyrolization chamber;

an air manifold being coupled to a first blower for supplying a first source of combustion air across the top of the combustion/pyrolization chamber and forming an air curtain during operation of the first blower as well as supplying the first source of combustion air to the combustion/pyrolization chamber;

a char collection/transfer chamber being located below the perforated grate for collecting the at least char and biochar that passes through the perforated grate, and the char collection/transfer chamber having a conveying mechanism for transferring at least the char and biochar out of the combustion/pyrolization system for collection;

an air plenum chamber being coupled to a second blower for supplying pressurized secondary air to the char collection/transfer chamber, the secondary air being heated as the secondary air flows through and cools the char collection/transfer chamber, and the heated secondary air eventually flows into the char collection/transfer chamber and through the perforated grate thereby providing secondary combustion air for the combustion/pyrolization chamber; and

a viewing device which permits viewing of the combustion/pyrolization chamber by an operator, and the viewing device being attached to a movable stand which is movable from a storage position to a deployed position, and vice versa, and the viewing device, when in the deployed position, facilitates viewing of the combustion/pyrolization chamber.

2. The combustion/pyrolization system according to claim 1 , wherein the char collection/transfer chamber is located between the air plenum chamber and the combustion/pyrolization chamber.

3. The combustion/pyrolization system according to claim 1 , wherein a base surface of the char collection/transfer chamber is shaped to form a plurality of troughs, each one of the plurality troughs accommodates a respective conveying auger, and each respective trough directs at least the char and biochar, from the combustion/pyrolization chamber, toward the respective conveying auger for conveyance toward a discharge end of the combustion/pyrolization system.

4. The combustion/pyrolization system according to claim 3 , wherein a heat conductive medium is supplied to the char collection/transfer chamber to assist with quenching of at least the char and biochar which passes through the perforated grate and accumulates within the char collection/transfer chamber.

5. The combustion/pyrolization system according to claim 1 , wherein a base surface of the char collection/transfer chamber is shaped to form a plurality of troughs, and each respective trough directs at least the char and biochar, from the combustion/pyrolization chamber, toward a bottom portion thereof for conveyance toward a discharge end of the char collection/transfer chamber.

6. The combustion/pyrolization system according to claim 5 , wherein a heat conductive medium is supplied to the char collection/transfer chamber for at least partially quenching the char and biochar which passes through the perforated grate and accumulates within the char collection/transfer chamber and conveying the char and biochar out the discharge end of the char collection/transfer chamber for further processing.

7. The combustion/pyrolization system according to claim 1 , wherein sidewalls of the combustion/pyrolization chamber are defined by a plurality of ceramic members, a first end ceramic member and a movable second end ceramic member, the movable second end ceramic member is movable into a first open position to facilitate removal of accumulated char, biochar, ash, clinkers, soot, unburnt debris from the combustion/pyrolization chamber.

8. The combustion/pyrolization system according to claim 1 , wherein the base frame is supported by a drive assembly which facilitates movement of the combustion/pyrolization system, and the drive assembly comprises one of wheels or a pair of drivable tracks which facilitate movement of the combustion/pyrolization system to a desired location.

9. The combustion/pyrolization system according to claim 1 , wherein the perforated grate is fabricated from metal and has a thickness of between ⅜ and 4 inches, and the plurality of holes formed in the perforated grate facilitate at least the char and biochar passing through the perforated grate and collection in the char collection/transfer chamber as well as passage of the secondary air through the plurality of holes into the combustion/pyrolization chamber to facilitate combustion of the feed material.

10. The combustion/pyrolization system according to claim 1 , wherein an interior of the air manifold gradually tapers internally cross sectional area from a first end of the combustion/pyrolization chamber toward the second end of the combustion/pyrolization chamber where the air manifold terminates.

11. The combustion/pyrolization system according to claim 1 , wherein at least one nozzle is installed within the combustion/pyrolization chamber and connected to a fuel source, an igniter is associated with the at least one nozzle to assist with generating a spark and initiating a flame, when fuel is supplied from the fuel source to the at least one nozzle, and thereby ignite the feed material contained within the combustion/pyrolization chamber.

12. The combustion/pyrolization system according to claim 1 , wherein a control panel is affixed to the combustion/pyrolization system, and the control panel controls operation of an engine, a pump and a supply of hydraulic pressure to a drive assembly in order to control turning and both forward and reverse travel of the combustion/pyrolization system.

13. The combustion/pyrolization system according to claim 12 , wherein a handheld remote radio controller communicates wirelessly with the control panel.

14. The combustion/pyrolization system according to claim 1 , wherein an engine is supported on the base frame, the engine drives a hydraulic pump which generates a source of hydraulic pressure for controlling operation of the combustion/pyrolization system.

15. The combustion/pyrolization system according to claim 1 , wherein the base frame is supported by a stationary assembly.
