Talk:Wood gas

(First comment)
Alternativelly wood gas can be used to directly heat an external combustion engine such as an Stirling engine; one advantage would be to avoid the cleaning of the generated gas, hence, cooling down process and combust the gas avoiding any drop outs such as tar or water. Alltogether it would be one way to take advantage of the total biomass of forests and not leave 50% or more of the biomass unused or as waste. RockEnergy 10:59, 18 April 2006 (UTC)

It says in the begining of the article that wood gas is also known as producer gas, syngas and water gas. The latter two are definetively not wood gas. Water gas is made by an entirely different technique. Syngas is made at higher temp and under more controlled conditions than wood gas. Producer gas seems to be general term for gases that are mixed, i.e. both wood gas and syngas are producer gases. So have removed the mention in that sentence of syngas, producer gas and water gas. the other I do not know. (Holz gas is probably a German term, the Swedish term is gengas) Benkeboy 16:42, 29 April 2006 (UTC)

Change redirect for Producer Gas?
I believe that Producer Gas should get a mention in Manufactured Gas Plant and the redirect for Producer Gas go there instead of wood gas.

Producer gas is the production of mostly hydrogen gas through the heating of charcoal and the addition of steam.

Wood gas is destructive distillation and contains mostly carbon monoxide along with (to a lesser degree) hydrogen and many hydro-carbons to a lesser degree. Jm butler 17:17, 17 September 2006 (UTC)

This page should include a link to "Charcoal" and to "Pyrolysis". The pyrolysis of wood produces a solid; the charcoal, and also gasses; the "wood gasses". These are all related concepts. I haven't figured out how to add links or I would do it myself. Alexander SelkirkAlexselkirk1704 (talk) 17:35, 12 April 2008 (UTC)

Heating value?
The "Usage" paragraph states that "The gasification stage converts about 75% of fuel energy content into a combustible gas that can be used as fuel for internal combustion engine." However, the heating value (LHV) is later given as about 5 MJ/kg while the heating value of wood is given as 15 MJ/kg. If the 75% conversion ratio were to be correct, the LHV of wood gas would be around 10, not 5. Can someone check all these numbers specifically the 75% which looks high to me? Thanks!

Seems that you mix things. Heat value of gas and heat value of wood have nothing common together. Air contains 79 persents inerts (N2 and Ar) which increase the amount of gas. —Preceding unsigned comment added by 82.128.238.107 (talk) 13:09, 27 January 2010 (UTC)

Well, I feel that the heating value of wood gas and wood are indeed related since wood gas is made from an "incomplete" combustion of wood in air. G.C. —Preceding unsigned comment added by 69.157.3.207 (talk) 05:04, 14 February 2010 (UTC)

Popular Culture
Like it or not, a wood gassifier was used on the tv series “The Colony.” The page should include an section on popular culture with specific reference to this event. (I don’t want to go so far as to say “current examples” considering all the surrounding factors, but should be mentioned.)174.25.121.131 (talk) 01:16, 23 September 2010 (UTC)A REDDSON

How about pressurized storage?
I did not notice any mention about pressurized storage of wood gas. Is it too trivial? Has it been ever used for wood gas? Is it actually the same thing as storage of coal gas? —Nikolas Ojala (talk) 09:08, 23 July 2018 (UTC)

One of the referenced books in this aticle has been blacklisted
I tried to add a link to one of the books that was cited in this article (www.ekomobiili.fi/Tekstit/available%20drawings.htm), but this link is on Wikipedia's spam blacklist. Is this book available online from another (non-blacklisted) source? Jarble (talk) 02:23, 27 January 2019 (UTC)

Dubious
The following was added to the article on 20 September with this edit: I've moved it here and marked the relevant passage as dubious. Moonraker12 (talk) 19:38, 3 October 2022 (UTC) This edit regards the above statement, "Wood does not release any carbon from fossil reserves underground". That is only kind-of true at best, while misleading altogether with respect to carbon emmissions. Here's the expanded story... You may have noticed that the ground does not subside in forests where trees grow, begging the question, "From where does the non-water mass of trees come, if not from the ground?" The answer is, "Thin Air", or rather, from the carbon dioxide in that thin air. Trees and most other plants breath in air which is 0.04% CO2, and through the process of photosynthesis separate the carbon from the oxygen, releasing the O2 back into the atmosphere while sequestering the carbon into the "body mass" of the tree itself. So while burning "Wood does not release any carbon from fossil reserves underground" directly, when burned, wood does re-release all its carbon, much in the form of CO2, including any fossil-carbon it ever sequestered.

 * I think you are a kind and special spirit very near me, I welcome you to state honestly how close your understanding is. First please note there are vehicles running on this. I apologise if there is a wording that is less misleading please do express. It is the *from underground* bit that matters. The fact it only releases carbon from the air that it took in growing that you have explained. This makes it "carbon nutral"Typo Team to most effects, because burning the oil that is already underground releases the trapped carbon. Which is mad bad init fam. 81.129.99.229 (talk) 00:42, 11 October 2022 (UTC)
