Wood Gas Generation full blast

Them play with with high voltage low amp signal through the fire to light the hydrogen if the heat isn't enough

[lbdavisjr]

You should try superheated steam injection you'll burn the hydrogen right out of the water and make more power

[MarkLeavenworth]

Apart from chemistry, steam creates an efficiency feedback loop, that produces the most steam with the least excess heat. But including the chemistry, a portion of steam absorbs by-products of the combustion, promotes the transfer of heat, for fire and end use of the fuel, and increases the heat concentration of the fuel gas if a certain portion of cracked steam can be added. But I'm just trying to provide any ideas to you and anyone else trying to produce their own fuels.

[MarkLeavenworth]

I haven't had time to try much of this apart from my little charcoal forge and a few test furnaces, but I think you can add in a measure of dry steam at the beginning and mix the out with air in various burner/mixers to optimize the whole arrangement.

I've read about that in a gasification book that I have. I don't remember the name of the specific process, but it is used to make hydrogen. However, I recall that it wasn't a continous process. The steam would eventually cool the gasification process down to the point it wouldn't crack the steam.

[MarkLeavenworth]

I did set up a steam tank on a wood fire blowing steam back into the fire, and the arrangement produced the most efficient burn and steam producing fire for the longest time (about 4 times longer than in a similar fire in the open air). I expect to use that principle to advantage at some point. There must be a similar arrangement that can self-govern the steam cracking process without more skill and effort than us amateurs can muster.

[turbomoore]

I don't see how injecting steam is going to do anything other than continously cool the process down and displace air needed for gasification.

@turbomoore

The process is most likely the Blue Gas process

two stages:

first, air (or purified oxygen) is blasted through a bed of hot coals, generating a lot of excess heat. Exhaust is vented

(C + O2 -> CO2 + heat)

then, steam is blasted through the hot bed, generating a high hydrogen content syngas. minimum H2:CO ratio is 1:1

(C + H2O -> CO + H2)

Ideally, by premixing dry steam and air/oxygen, this could be made a single step.

@coldsn I'm gonna give steam injection a try on the new gasifier I'm currently building for the F150.The free heat from the exiting WG and/or the engine's exhaust manifold would be plenty for making dry steam. I've since removed the current WG unit from my truck in the other video for a larger one with upgrades..I give the old one to my dad for a 4cyl genset he wants to mess with.

woodgas= natural gas power, there are natural gas powered cars.

only pressure in gas balons are very high= 300 bar, but its possible, need diver air compressor and water diving gas baloons....

Great gasifier, powerful flame!

[turbomoore]

I've been reading into that also as I'd like to further refine the resultant gases. However with different gases of different desinties I suspect the gases will seperate while in the container they are stored in. Also I'd be weary of using a traditional home air-compressor due to the risk of explosion (from the H2 gas present).

[colby620]

I am working on a stationary wood gasifier like yours, only trying to capture the gas with an air compressor. So you can transfer the gas into tanks. Any thoughts or ideas. Have you already tried it?

[benknefelkamp]

i've heard its a bad idea because the amount you would need to compress would be way too much. just mount the generator on whatever you are gonna use
