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.

FEMA wood gasifier demonstration and DIY specifications (biogas forum at permies)

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. Section 1 describes gasification principles and wood gas generators, in general, and gives some historical background about their operation and effectiveness. I consider the primary purpose of this forum as a resource for education, and I’m trying to encourage the reader to take the claim seriously.

A closure is only used to preserve the fuel when the engine is stopped. Both the Imbert gasifiers and the stratified concept have a provision for shaking the grate; when they are used to power vehicles, they are automatically shaken gasicier the vehicle’s motion. Very little to no tar mess to be disposed gasifoer or dealt with.

I have to disagree with you on one point and vasifier is whether this femz is a proven design. I wouldn’t run a car on a FEMA unless it was a one-way trip Pick your direction based on the zombie apocalypse de jour but for a cheap briggs engine, sure. In these twin tasks lie its advantages and its difficulties. The purpose of this design is to get engines running quickly for essential functions when only biomass is available as fuel.


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 fuel is not quite as robust because the tar is a wasted “potential” fuel.

FEMA Gasifier

Fuel gas, produced by the reduction of coal and peat, was used for heating, as early as in Europe, and by it had been adapted to fuel engines in England. Solar Dehydrator Plans – Ffema Package download. The liquid fuels used in gasoline engines are vaporized before they enter the combustion chamber above the pistons.

The FEMA design is generally suited to introduce wood gasification and many variations of this design do power vehicles without destroying them.

Thanks for the added link. The purpose of this report is to develop detailed, illustrated instructions for the fabrication, installation, and operation of a biomass gasifier unit i. Awesome point glad someone made itthere are going to be a lot gasifiee peoples uses and fuel sources that will differ gasivier use to useand there several types of gasifiers as well Most of the volatile components of the fuel are burned in this zone and provide heat for continued pyrolysis reactions.

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 gasifierr presented the design very clearly. During operation of this gasifier, air passes uniformly downward through four zones, hence the name ‘stratified: The cylindrical shape is easy to fabricate and permits continuous flow of fuel.

This simplified design employs a balanced, negative-pressure concept in which the old type of sealed fuel hopper is no longer necessary. Your spouse will KILL you when some of it gets on the furnature gzsifier your clothes. The United States, never faced with such prolonged or severe oil shortages, has lagged far behind Europe and the Orient in familiarity with and application of this technology; however, a catastrophe could so severely disrupt the supply of petroleum in this country that this technology might be critical in meeting gasififr energy needs of gasirier essential economic activities, such as the production and distribution of food.


This report attempts to preserve the knowledge about wood gasification as put into practical use during World War II.

It can be built with a minimum of tools. Personally, I believe that a FEMA system could be optimized for a very particular fuel and, if run at a more or less constant output, then I believe it could make a reliable ffema useful unit.

A more robust gas producer. These instructions have been prepared as a manual for use by any mechanic who is reasonably proficient in metal fabrication gasiffier engine repair. Therefore, in any case I expect a FEMA design to introduce tar into an engine at a rate many times higher than an Imbert all else equal.

There is a surprising duration of energy generation and the model can be scaled to meet higher energy requirements. Bats – your most effective insect control. However, this report is concerned with the operation of four-cylinder gasoline engines rated from 10 to horsepower.

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