Wood Gasifier

Burn

Classic build - 55 gallon drum, shaker, starter tube. Need to look at FEMA instructions for relative sizing.

Tar Vortex

I want to do a lot of cooling at this stage. The chamber will have water cooling around it. Typically these are built from steel, but I think aluminum will work better to allow greater thermal flow.

Cooling Tower

Out of the tar vortex I'll have a manifold rising. The bottom will form a slight V so that any condensation will drip back into the tar collector. The tower will have forced air that then passes goes into the burn chamber. This will preheat the air. I think these could be made from aluminum conduit.

Water Filter

The gas then enters a tube that also contains a spray of water. I think there will also be plastic medium to increase surface area.

Condenser

Not sure if this is necessary. Gas passes through an aluminum heatsink attached to a peltier device. This should cool the air enough to cause any moisture to condense. The heatsink is mounted vertically and the air comes in from the top. The gas then goes down and back up to pass over a second heatsink connected to the other side of the device which then reheats the air. This should allow the peltier to perform very efficiently.

Generator

At this point the gas should be clean enough for the generator. Need a two valve setup to balance the air mixture.

Air Circulation

Air is forced in, first passing over the cooling towers. The air is forced in the top so it runs counter to flow of air in the tubes. It then over a radiator that cools the water used in the tar vortex. The water is flowing counter to the air. This air then passes into the burn chamber. It should already be well above 200F. This should help dry the wood and allow for more efficient combustion.
