During operation of this gasifier, air passes uniformly downward through four zones, hence the name ‘stratified: The reader is urged to use his ingenuity and initiative in constructing his own wood gas generator.
Femaa 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. Thousands of gas works all over the world were eventually dismantled. I think it’s important to provide this kind of disclaimer whenever the FEMA is introduced, especially for those new to the technology. The inert char and ash, which constitute the fourth zone, are normally too cool to cause further reactions; however, since the fourth zone is available to absorb heat or oxygen as conditions change, it serves both as a buffer and as a charcoal storage region.
Notice the gap between the matchstick and the luminous flame; this gasiifcation contains the wood gas which starts burning only when properly mixed with air which contains oxygen. Stationary engines can also be fueled by wood gasifiers to run electric generators, pumps, and industrial equipment. This is an important distinction.
So, there is some evidence that a few relatively simple modifications to the FEMA can dramatically improve its performance.

The problem with this is that an engine powered by such a unit will require a lot of regular maintenance. The cylindrical shape is easy to fabricate and permits continuous flow of fuel.
All over Europe, Asia, and Australia, millions of gas generators were in operation between and In short, this design i. Your spouse will KILL you when some of it gets on the furnature from your clothes. Two-thirds is lost into the environment with the smoke.
The purpose of this design is to get engines running quickly for essential functions when only biomass is available as fuel.
Beforegas generator units were a familiar, but not extensively utilized, technology. This simplified design employs a balanced, negative-pressure concept in which the old type of sealed fuel hopper is no longer necessary.
In fact, many people can recall a widespread use of wood gas generators during World War Fem, when petroleum gasificatiin were not available for the civilian populations in many countries. However, this report is concerned with the operation of four-cylinder gasoline engines rated from 10 to horsepower.
I would stop short in calling this particular design as “proven” In the second zone, the wood fuel reacts with oxygen during pyrolysis. Such knowledge is not necessary for constructing and operating a wood gasificatiion. You can have multiple engines and rebuild kits for less than the cost difference to get to an Imbert.
High-grade biomass fuels such as wood blocks or chips will flow down through the gasifier under the influence of gravity, and downdraft air flow. This gsification, stratified, downdraft gasifier unit can be constructed from materials that would be widely available in the United States in a prolonged petroleum crisis. I consider feam primary purpose of this forum as a resource for education, and I’m trying to encourage the reader to take the claim seriously.

Such manufactured gas was used for street lights and was piped into houses woor heating, lighting, and cooking. As the wood gas burns, the products of combustion are carbon dioxide CO2 and water vapor H2O.
Cema the restriction plate to the base of the fire tube serves a couple functions: Because of the wood gasifier’s somewhat low efficiency, the inconvenience of operation, and the potential health risks from toxic fumes, most of such units were abandoned when oil again became available in These instructions have been prepared as a manual for use by any mechanic who is reasonably proficient in metal fabrication or engine repair.
Adding additional insulation can further raise temperatures there which is important for tar reduction.

The FEMA is a good unit for learning, so in that sense it can be useful beyond an emergency unit. For example, the body of the unit gasirication of a galvanized metal garbage can atop a small metal drum; common plumbing fittings throughout; and a large, stainless steel mixing bowl for the grate.
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.
My line of reasoning is well supported by those with experience, and I encourage all readers to investigate other forums on this topic including driveonwood.
