Benefits of technology

Enables efficient, complete combustion of various materials without supplemental fuels, prolongs system operation by continuous ash discharge, and reduces carbon release by preserving char for further use.

Problems solved by technology

Vegetative material, in particular wood, has long been a difficult problem for community landfills, lumbering operations and cleanup operations after a natural disaster.
Grinding wood reduces its volume, but is relatively expensive and can be harmful to the environment, and, in any event, it still fails to reduce the amount of wood.
Moreover, in the context of a massive tree kill, due to insect infestation and / or climate change, for example, the approach of grinding, chipping and hauling the wood does not solve, but can actually spread the problem.
These portable solutions offer relatively clean burning and also minimize the need to transport the material, however, they both still suffer from a number of associated drawbacks, e.g., the material is completely burnt thereby releasing into the atmosphere the carbon contained in that material.
It is to be appreciated that currently available fireboxes and fire pits are typically costly to move or transport from one job site to another job site.
In addition, it is typically tedious and time-consuming to move a firebox or a fire pit from one location, on a job site, to another different location, on the same or a different job site.
Further, such repositioning often includes required assembly effort and time when arriving at a new job site.
This is a serious drawback concerning the currently available fireboxes and fire pits.
However, trench burners typically require preparation work to be performed at the job site, such as digging a ditch in order to accommodate the trench burner.
In addition, the currently available trench burners, fireboxes and fire pits do not have any system for automatically removing the char, biochar, ash, clinkers, soot, unburnt debris, etc., which eventually accumulate within the combustion chamber while burning the vegetative material and / or biomass.
Accordingly, removal of the char, biochar, ash, clinkers, soot, unburnt debris, etc., tends to be a dirty, cumbersome, tedious, and time-consuming exercise.
In addition, since the material remains within the trench burners, fireboxes and fire pits for prolonged periods of time, the material is generally completely burned thereby releasing all of the carbon contained within the material into the atmosphere.
Moreover, the currently available trench burners, fireboxes and fire pits typically lack an adequate supply of combustion air to the combustion chamber, particularly the lower portion of the combustion chamber.
This lack of adequate combustion air inhibits efficient combustion, whether to completion or as an initial step in the pyrolysis process, of the vegetative material and / or biomass within conventional burners, fireboxes and fire pits.
Further, the currently available trench burners, fireboxes and fire pits are typically not equipped with any automated or semi-automated ignition system which facilitates igniting the vegetative material and / or biomass contained within the combustion chamber.
Such technique is generally an inconvenient way of igniting the vegetative material and / or biomass and may possibly create a potentially dangerous or hazardous situation.
Lastly, it is to be appreciated that the currently available trench burners, fireboxes and fire pits are not equipped with any automated feed mechanism for feeding additional material into the combustion chamber for consumption, as periodically required by the combustion chamber.
In addition, none of the currently available trench burners, fireboxes and fire pits have any visual aid which assists an operator of the equipment with viewing combustion of the vegetative material and / or biomass occurring within the combustion chamber.
Even with the recent advances which have occurred in the art, biomass incineration facilities and / or portable apparatuses still suffer from a number of associated drawbacks.

first embodiment

[0044]Turning first to FIGS. 1-5A, a brief description concerning the various components of the present invention will now be briefly discussed. As can be seen in this first embodiment, the present invention relates to a self propelled portable (or possibly a stationary—see FIG. 14) combustion / pyrolization system 2 which can be easily and readily transported to a desired location or site and set up in order to facilitate partial or substantially complete combustion / pyrolization of the desired feed material 4, e.g., all types of material such forestry debris, vegetative debris, biomass, processed and unprocessed wood, chips, bark, ground wood and well as other materials such municipal solid waste (MSW). The portable combustion / pyrolization system 2 comprises a base frame 6 upon which the components of the system are assembled.

[0045]An engine 12 (see FIGS. 1, 5 and 13), e.g., a 50-150 horsepower diesel powered engine or possibly a plurality of electric motors, is supported on the base...

third embodiment

[0095]The major difference between the third embodiment and both of the previously embodiments relates to the additional feature of a heat exchanger 106 provided adjacent the open top of the combustion / pyrolization chamber 40. According to this embodiment, a conventional heat exchanger 106 is located along the second longitudinal side of the combustion / pyrolization chamber 40, opposite the air manifold 72. The heat exchanger 106 has both a retracted position (see FIG. 11) as well as an engaged or active position (see FIG. 10). The retracted position may be utilized when the feeding of feed material 4 into the combustion / pyrolization chamber 40 is occurring or when the water or oil, which is flow through the heat exchanger 106, becomes sufficiently heated or is possibly overheated by the combustion / pyrolization process.

[0096]As generally diagrammatically shown in FIG. 9, a source of water or oil 108 is connected, via a flexible or movable inlet conduit or pipe 110, to an inlet end of...

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.

Grinding wood reduces its volume, but is relatively expensive and can be harmful to the environment, and, in any event, it still fails to reduce the amount of wood. Moreover, in the context of a massive tree kill, due to insect infestation and / or climate ch...
