This is one of the nicest compact wood gasifiers I have seen to date, there are many large well built ones I have seen but very few compact well built ones in my opinion.

Joshua Burks has a very detailed 9 part video series in where he shows you step by step with great explanations as to why and how he built his.

I am providing a link for his demo video, you can view the video series via his youtube channel or on his website at the link provided below as well.
Thanks Joshua for putting together a very well how to build video series.

Also for the purpose of ease, here is a link to his video series on how to build the stove, he has it all lined out for us.
Thanks again Joshua.

Personally I have never had luck with a fema gasifier.

I will post up a simple modified imbert gasifier that will run an engine up to 15hp as soon as I can find the drawing on my computer. It's a system that was designed by my friend Stephen Abaddess and I have his permission to share it.

this doesn't have to be bolted together, it can be welded. Our unit that we sell is based on this geometry. just need to add a cooler and a filter.

I think I have seen this on youtube in action did your friend post a video on the actual build?

Looks like it is a partial drawing, hard to figure out the whole gist of the design.

The reactor parts are there and they are the most critical... coolers and filters are easy when you make good gas from the start.



this is what I started with when I began looking at building a gasifier.



and this was our first build from that description... and yes it made burnable gas. I have youtube of it running a genset

I have found most people in the world of gasification to be very helpful and willing to answer gasification questions. But don't ask specifics like can I have a dimentional drawing of your current system... that will usually shut the door on future assistance. Most people that have a system that has several hundred hours of runtime have put 1000's if not 10's of 1000's of dollars into their research and development so please don't be surprised if they tend to be a bit apart from the rest of the world.

If you are interested in gasifier math I'll happily share what I know in that respect. I'll happily share everything I know about coolers and filters....

it's not hard to gasify wood, doing it well, and repeatably can be.

Let me know what you want to know and I'll do my best to answer.

Thanks for the explanation, I understand the reluctance to not give up drawings, I myself battle with that and have decided that I am going to go ahead with doing just that as soon as time provides.

Or should I say make the time.

I like what gek is doing.

Yeah, I built a gasser a while back. I will be modding it to run on charcoal whenever I get the chance. Charcoal gassers can be built with just about anything. And you can make char from anything, too. If you want to know more, feel free to ask.

If you haven't already built a gasifier just build a charcoal gasser. Cheaper, easier, simpler, more flexible with fuel, lighter, smaller, and the likes. If I had to do it again I would do charcoal.

If you have a working gasifier, why mod it?

Also, while I did see someone run a grinder, please don't take this wrong but that doesn't mean much as it's probably less than 450 watts when not under load.

Not putting down your endeavour... I'm a fan of anything wood gas. People don't usually change things with out a reason. Typically those running char do so because they have made tar in a previous build. You can make tar if your wood isn't charred well too.


I know I can build a wood gasifier very cheaply if needed. less than 500.00 in materials, that would easily run a gen set, and doesn't make tar if used correctly. So why would I want to have to make char first? When you are making char, are you doing something with the waste heat? Boil water? I know a few fellows that do that for infloor heating or domestic hot water purposes.

I also know a few people that are looking at small scale char gassers to use the excess char their WK type mobile gasifiers make. Me I don't have that problem with the units I build... very little char left over from the wood chips I use.
