DETAILED DESCRIPTION OF THE INVENTION

The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention.

The present invention eliminates all pollution coming out of a regular wood burning processor. This innovation allows the smoke to be forced back into the fire. There is no other innovation that has a burner that carries the smoke back into the fire. The present invention burns wood with no odor or smoke. The present invention produces more BTU's than any other processor. The present invention burns cleaner than any current wood processor. The present invention and processes can use any type of wood for energy, even wet or dry. This process eliminates shredding or drying of any type of wood.
This invention is an improvement on what currently exists. This innovation forces the exhausting air to go through the incoming air. The exhausting air needs to pass through the intake air so the smoke is carried back into the fire. This is a forced air device that allows one to control direction of air flow. There is no other innovation that has a burner that carries the smoke back into the fire.
This device can be used to generate heat or steam pressure. It could also be configured to drive an electric generator. The abundance of btu's created by this device can be used as a heat source.

How The Invention Works:

When wood and propane are mixed together in a burning chamber the propane ignites, causing the wood to heat high enough to start the burn process with the vortex causing the smoke to recycle and completely burn.

How To Make The Invention:

Through the process of fabricating and welding all the components together and adding the necessary lines to supply propane gas and air to the burn chamber. The present invention includes an improved ignition system required to start burning process.

How To Use The Invention:

It will allow one to produce clean non polluting energy (btu's) for heating or producing btu's for bio-industrial power generating plants. This device can also be used to generate heat or steam pressure. It could also be configured to drive an electric generator. The abundance of btu's created by this device can be used as a heat source.
Referring to the drawings, a method of burning a fuel with high efficiency comprises:
providing a combustion chamber 10 having a combustion region (shown in FIG. 4 on the right side of the natural fuel 12, where combustion occurs);
providing a natural fuel 12 within the combustion chamber 10 on one side of the combustion region;
providing a filtered fuel 18 (such as propane, butane, gasoline, or any other liquid or gaseous fuel that, unlike natural fuel 12, which comprises a mixture of solid and liquid fuels, has been filtered);
providing a substantially cylindrical injector 16 on an opposing side of the combustion region, the injector 16 comprising: an exhaust port 38 in an axial center of the injector 16; a notch 42 surrounding a circumference of the injector 16; and a plurality of intake ports 40 in a periphery of the injector 16 and configured to port fluid (such as propane, air, any liquid or gaseous fuel or any liquid or gaseous oxidizer) from the notch 42 to the combustion region so that the fluid flows toward a center of the combustion region, the fluid comprising at least one of air and the filtered fuel; and
burning the natural fuel 12 within the combustion chamber 10 to produce a smoke 22 comprising combustible substances,
wherein the flow of the fluid toward the center of the combustion region, while the natural fuel is burning within the combustion chamber, causes at least one vortex 24 in which the combustible substances further burn with the air and the filtered fuel.
The method may further comprise: providing a spark capture chamber 32; separating exhaust 26 from the exhaust port 38 into gases and solids; and collecting the solids 30 in the spark capture chamber 32.
The method may further comprise removing heat from exhaust from the exhaust port, such as using the generated steam to power a generator, or using the heat to heat a house or hot water, etc.
The intake ports 40 may comprise substantially straight ports channeled from the notch 42 to an end of the injector 16 and angled relative to a central axis of the injector 16 by an angle of between approximately 5 and 30 degrees, more preferably between approximately 5 and 15 degrees, so that the resulting flowing fluid flows toward a center of the combustion region to create vortices 24. The injector 16 may comprise at least two, more preferably at least four, more preferably at least six, and more preferably at least eight ports 40. They may be all designated for filtered fuel, or for air, or some may be for filtered fuel while some may be for air, allowing mixing and combusting to occur in the combustion region. One or more of the drawings show the filtered fuel mixed with the air before entering the combustion chamber 10; however, in one embodiment these reactants are not mixed until entering the combustion chamber 10 as they are fed in separately.
It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention.
