This website is dedicated to the construction of wood gasifiers that can be used to run a gasoline engine with. Woodgas has been around for a long time and it. If you google “fema gasifier” there will be several documents that should pop up. Below is an example. and FEMA EMWE We’rk Unit D . gasifier unit (i.e., a “producer gas” generator, also called a “wood gas” generator) which is capable of.

No concerns of the fire climbing up through the wood hopper due gasifiier the wood hopper being a sealed oxygen free fuel holding vessel. Therefore, if one desires to fuel an engine over an extended period with biomass, then moving gxsifier the FEMA design is the wise decision.

This new technology has several popular names, including ‘stratified, downdraft gasification’ and ‘open top gasification. A schematic diagram of the stratified, downdraft gasifier is shown in Fig. Thus, the aim of gasification is the almost complete transformation of these constituents into gaseous form so that only the ashes and inert materials remain.

FEMA Gasifier

The FEMA gasifier was only meant as a last resort emergency fuel source so it was never intended to be used as a long term fuel source. You have to use harsh solvents such as gasoline to clean it off and when you stink your house up with the smell of tar and gasoline your spouse will make you give up your gasifier project and dreams or else they will KILL you and bury you in the back yard with it and tell your family that you left the country.

The first question many people ask about gasifiers is, ‘Where does the combustible gas come from? This report attempts to preserve the knowledge about wood gasification as put into practical use during World War II. If hasifier tars get on your hands or your gasifiee or tools you cannot use soap and water to wash it off.


The FEMA design is generally suited to introduce wood gasification and many variations of this design do power vehicles without destroying them. The tar can be used to tar your roof or your driveway. After the discovery of large petroleum reserves in Pennsylvania inthe entire gasiier changed to oil – a cheaper and more convenient fuel. The tars must be disposed of and they emit foul fems.

The solid, biomass fuels suitable for gasification cover a wide range, from wood and paper to peat, lignite, and coal, including coke derived from coal. If you research other forums frequented by those with experience such as driveonwood.

With good charcoal one can generate a clean fuel gas with a steel can and a couple of tubing connections see Gary Gilmore’s work. One of the most simple gasifier designs out there. The liquid fuels used in gasoline engines are vaporized before they enter the combustion chamber above the pistons.

So, there is some evidence that a few relatively simple modifications to the FEMA can dramatically improve its performance. The purpose of this report is to develop detailed, illustrated instructions for the fabrication, installation, and operation of a biomass gasifier unit i.

Being an open top air fed design, the fire from the reaction zone can climb straight up through the fuel and waste it and it can cause the gasifier to run very hot and inefficent.

The use of wood to provide heat is as old as mankind; but by burning the wood we only utilize about one-third of its energy. For prolonged idling, a hand-operated shaker has been included in the design. In creating wood gas for fueling internal combustion engines, it is important that the gas not only be properly produced, but also preserved and not consumed until it is introduced into the engine where it may be appropriately burned.

In the second zone, the wood fma reacts with oxygen during pyrolysis. You can have multiple engines and rebuild kits for less than the cost difference to get to an Imbert. Making a combustible gas from coal and wood began around in Europe. I am confident you have some insightful knowledge but this sounds a tad bit melodramatic to prove a point.


More to the point and my intention, I think it is polite to give credit to the person in the video who constructed a polished prototype and in my opinion presented the design very clearly.

In fact, the use of wood gas as a fuel is not even restricted to gasoline engines; if a small amount of diesel fuel is used for ignition, a properly adjusted diesel engine can be operated primarily on wood gas introduced through the intake manifold. Naturally, the people most affected by oil and petroleum scarcity made the greatest advancements in wood gas generator technology.

The guidelines must be met to match the Imbert to the engine it will be running to achieve the correct temperatures to gasifire the tars down into a useful part of the fuel.

Section gadifier contains detailed step-by-step instructions for constructing your own wood gas generator unit; illustrations and photographs are included to prevent confusion.

It should be acknowledged that there are alternate technologies such as methane production or use of alcohol fuels for keeping internal combustion engines in operation during a prolonged petroleum crisis; the wood gasifier unit described in this report represents only one solution to the problem.

He got good results using charred wood chunks in a FEMA gasifier to fuel his trucks. This unit was then mounted onto the front of a gasoline-engine farm tractor and successfully field tested, using wood chips as gaasifier only fuel; see Fig. Wayne Keith worked pretty well with a modified FEMA design not that I can attest to any working experience as my knowledge is through literature.

A more robust gas producer.
