Wood gas generatorFrom Wikipedia, the free encyclopedia

A wood gas generator is a gasification unit which

converts timber or charcoal into wood gas, a syngas

consisting of carbon monoxide,hydrogen, traces of

methane, and other gases, which - after cooling and

filtering - can then be used to power an internal combustion

engine or for other purposes. Historically wood gas

generators were often mounted on vehicles, but present

studies and developments concentrate mostly on stationary

plants.

Gasification had been an important and common technology which was widely used to generate

Town gas from coal mainly for lighting purposes during the 19th and early 20th century. When the

first stationary internal combustion engines based on the Otto cycle became available in the 1870s

they began displacing steam engines as prime movers in many works requiring stationary motive

power. Adoption accelerated after the Otto engine's patent expired.[when?] The potential and

practical applicability of gasification to internal combustion engines were well-understood from the

earliest days of their development.

In 1873, Thaddeus S. C. Lowe developed and patented the water gas process by which large

amounts of hydrogen gas could be generated for residential and commercial use in heating and

lighting. Unlike the common coal gas, or coke gas which was used in municipal service, this gas

provided a more efficient heating fuel.

During the late 19th century internal combustion engines were sometimes fueled by town gasand

during the early 20th century many stationary engines switched to using producer gas created from

coke which was substantially cheaper than town gas which was based on the distillation (pyrolysis

more expensive coal.

In about 1920 Frenchinventor Georges Imbert created the "Imbert" downdraft generator.

During World War IIgasoline was rationed and in short supply in both Great Britain and in the Uni

States and large numbers of such generators were constructed or even improvised to convert wood

and coal into fuel for vehicles. Commercial generators were in production before and after the war

use in special circumstances or in distressed economies.

The US Federal Emergency Management Agency (FEMA)

published a book in March 1989 describing how to build a

gas generator in an emergency when oil was not available.

A project about the energy future of Europe was begun in

2005 in Gssing, Austria with contribution of European

Unionresearch furtherance. The project consisted of a

power plant with a wood gas generator and a gas engine

to convert the wood gas into 2 MW electric power and

4.5 MW heat. At the wood gas power plant are also two

containers for experiments with wood gas. In one container is an experiment to convert wood gas,using the Fischer-Tropsch process, to a diesel-like fuel. By October 2005, it was possible to conve

5 kg wood into 1 litre fuel.

There is a rich literature on gas-works, town-gas, gas-generation, wood-gas, and producer gas, th

is now in the public domain due to its age. [1 ]

Most successful wood gas generators in use in Europe and the United States are some variation o

the earlier Imbert design. Wood gas generators often use wood, however charcoal can also be use

as a fuel, it is denser and produces a cleaner gas without the tarry volatiles and excessive water

content of wood.

The FEMA unit from 1989 has distinct benefits over the earlier European units such as easier

refueling and construction but is less popular than the earlier Imbert design because of significant

new problems, which include a lack of a fixed oxidization zone and allows the oxidization zone to

creep to a larger area, causing a drop in temperature; a lower operating temperature leads to tar

production and it lacks a true reduction zone further increasing this design's propensity to produce

tar. Tar in the wood gas stream is considered a dirty gas and tar will gum up a motor quickly,

possibly leading to stuck valves, and rings.

The United Nations produced the FOA 72 document with details about their wood gas generator

design and construction, as does World Bank technical paper 296.[2][3]

Wood gas generators have a number of advantages over use of petroleum fuels:

They can be used to run internal-combustion engines (or even gas turbines, for maximal

efficiency) using wood, a renewable resource, and in the absence of petroleum or natural gas,

example, during a fuel shortage.

They have a closed carbon cycle, contribute less to global warming, and are sustainable in

nature.

They can be relatively easily fabricated in a crisis using materials on hand.

They are far cleaner burning than, say, a wood fire or even a gasoline-powered engine is (with

emissions controls), producing little if any soot.

When used in a stationary design, they reach their true potential, as they are feasible to use in

small combined heat and power scenarios (with heat recovery from the wood gas producer, an

possibly the engine/generator, for example, to heat water for hydronic heating), even in

industrialized countries, even during good economic times, provided that a sufficient supply of

wood is attainable. Larger-scale installations can reap even better efficiencies, and are useful fo

district heating as well.

The disadvantages of wood gas generators are:

the large specific size

the relatively slow starting speed; the time to heat the initially cold batch of wood to the

necessary temperature level can take many minutes and in bigger plants even hours until the

designed power is reached.

a batch burning operation, that some designs feature, and that regularly interrupts the gas

producing process.

the stop operation out of a high load level is difficult (for example the stop of the engine using

gas): the residual heat still produces gas, which for a certain time leaves the gasifier either

without control, or has to be used in a burner

the primary combustible fuel-gas produced during gasification is carbon monoxide: it is an

intentional fuel-product, and is subsequently burned to safe carbon dioxide in the engine (or oth

application) along with the other fuel-gases; however, continuous exposure to carbon-monoxide

can be fatal to humans even in small to moderate concentrations.

the humidity of the wood (usually 15 to 20%) and the water vaporcreated by the O- and H-ato

of the dry wood itself (about 0.4 liters of water loaded with organic substances per kg of dry

wood) condenses during the gas cooling and filtering procedure and yields a liquid (see also

wood tar), which needs specific waste watertreatment. This treatment requires about 25 to 35

of the created wood gas energy.

When not carefully designed and used, there exists considerable potential for injury or death due t

wood gas containing a large percentage of poisonous carbon monoxide (CO) gas. Wood gasifiers

proven design and thoroughly tested construction are considered safe to use outdoors, or in a

partially enclosed space, for example, under a shelter open to the air on two sides; they may also

considered relatively safe to use in an extremely well ventilated (e.g. negative pressure) indoor are

not connected to any indoor area used for sleeping, equipped with redundant (more than 1),

completely independent, battery-powered, regularly tested carbon-monoxide detectors. However,

prudence must dictate that any sort of experimental wood gasifier design or new construction be

thoroughly tested outdoors, and only outdoors, with a "buddy" at all times, and with constant vigila

for any sign of headache, drowsiness, or nausea, as these are the first symptoms of carbon

monoxide poisoning.

In addition, mixtures of excessive quantities of air and gas should be avoided as this could lead to

the deflagration (explosion) of the gas in question if a combustion source is present. Long-term

storage of wood-gas, except through the use of a gasholder-type water-displacement apparatus,

should not be attempted, due to the volatile elements present in the gas, which, if allowed to

excessively precipitate, will condense in the storage vessel. Under no circumstances should wood

gas ever be compressed to more than 15 pounds per square inch (1.0 bar) above ambient, as this

may induce condensation of volatiles, as well as lead to the likelihood of severe injury or death du

to carbon monoxide or deflagration if the vessel leaks or fails.[citation needed]

In 2009, another example of designing and constructing a working wood gas powered generator

engine was in the TV series The Colonyin the second episode of the first season "Power Struggle

Also used in the tenth episode "Exodus" to power an escape vehicle.

In 2009 21stCenturyMotorworks was reported on mass media[citation needed] to have developed

gasification technology in a prototype pickup truck that could use any biomass materials for fuel. T

vehicle was displayed at multiple events including the 2009 Boston Greenfest. 21stcenturymotorwo

has since been involved in developing a circumferential engine technology to improve the efficienc

of biomass fueled energy systems. A new subsidiary, Eden Energy Solutions of Ct, is furthering

development of residential based energy units involving a combination of these two technologies.

A 2010 Mother Earth News article discussed and showed pictures of a wood gas powered engine

installed in a pickup truck.[5 ]

As part of the BBC science series "Bang Goes The Theory", a Volkswagen Scirocco was converte

to a design by Martin Bacon to run on used coffee grounds, and after its build in 2010 was driven

solely on coffee from London to Manchester successfully. Part of the team are now working on a

more advanced design leaning towards top speed as opposed to range.

online book digitization projects, such as Google Books, and these often have such materials

downloadable in full, as they have passed into the public domaindue to their age. For example,

searching for "Producer Gas", "Gas manufacture and works", or "Gas Generators" on
