burned it for about another hour today… hasn’t exhibited any plugging… shut it down as air tight as I could make it… gonna try one more thing tomorrow and if it’s looks right i’ll see about putting together a filter train for it. It flared huge, just there was a lot of moisture in it as you could squish the water out of the chips we’re using. So I know we’re making some tar… I don’t have any provisions for catching hopper condensate in this unit… I will in the next one for sure. And yes it looks like there will be an next one

I can say even with wet chips this new little reactor seems to make char no problem. Every time that I’ve had to clean it out to make a change there has always been char well over what would be considered the nozzle ring.

Ran for about 2 hrs today. Unit started to seem like it was sputtering near the very end… again, I’ve capped it all off as airtight as possible. We’ll see what it’s like inside tomorrow in the am. I still think that while my grate spacing was too large on the first grate it’s design worked the best. I may try to redo it in a similar fashion but with smaller spacing.

So are you running it like a charcoal gasifier?

I put wood in the top and it makes its own char… like all gasifiers do… I don’t consider it a charcoal gasifier though it sure makes its share.
Hey Arvid, lots of great info. Thank you for sharing.
I haven’t watched the latest set of videos, though. Mainly, there’s 7-ish videos and they are all named roughly the same thing “wood gas gasifier project” or “new wood gas gasifier project”. Could you please rename them as something like “07-10-15 wood gas gasifier project #1…2…3…” etc?
Thank you. Keep up the great work!
Heck I’m just happy I can remember what I originally named them so there can be some continuity. They are renamed now…

another hour burn time on it… this time with the new grate that I took a couple hours to put together… I think this one might just be the one… here’s hoping at any rate.

I put an extension pipe between the gasser body and ejector… hey look at that, the gasifier body doesn’t get as hot from the flame pouring out of the swirl burner.
Another hour burning… wind is crazy strong so i had to put a cage around it to keep it from getting blown out.
I’ll clean it out tomorrow and inspect the grate… if it looks reasonable I guess it’s time to think about a filter train and cooler so i can try the genset on it.

Hello Arvid; Been enjoying your postings for a long time. You have been very successful in designing and build several working gasifiers. One thing missing is you never tell us what or how you are doing-- just results. I understand that you have taken Steven’s work and expanded on it. Do you have plans of pattening your design or going commercial and selling units? If so I do understand why you are short on details of your builds
That brings us to the latest build. All I see is a grease barrel with a pipe at the bottom with Steven’s ejector. There might be a pipe on the opposite side. Is this a cross draft gasifier??? A cross draft would not be new, but making it work well, would be. I would enjoy knowing basically what you are doing so I can kind of enjoy the progress as you make it.TomC

Tom, Arvid always says on the hangout “if I told you I’d have to kill you” and then he laughs like he don’t mean it.

I do actually sell systems.
The latest build that I’m testing isn’t a cross draft… though in some ways may operate kinda like that. If I opened the lid and show you a picture there wouldn’t be any secrets at all… and then I’d have to kill you… lol.

Hey TomC, look at this topics tilte of International Supply and me (ArvidO)
Realize that he does, design and make these for commercial selling. They have a selling web-site.
ArvidO, Matt Ryder, Chris Seymour, Sean French ALL designing and manufacturing for commercial selling.
We all should just be happy with what they are willing to put up about their systems evolving results and capabilities.
Others DOW members like like the Thailand fellow, the New Zealand fellow, a couple of three, show-all Amercan youtubers are open source showing all.
Even once all open source APL/GEK very closed mouth about thier proprietory patent developements in the last few years.
Takes all kinds to make the wood-for-power endevor world go around man.
I think here on the DOW as accepting to all approches that the glass still remaings over half full; info re-filling.
Regards
Steve Unruh

Ahhh I guess I stepped into something that everyone but me knew was going on. I did not know Arvid was making a business of woodgasification. I thought International Supply, and me was his business making something out of lumber. As I said in my post, I totally understand his position if he is going to patten the design or if he is manufacturing them for sale. So I do understand now and I apologize for being overly inquisitive. Don’t misinterpret my apology, Arvid lives in Canada if I understand that part correctly and he would have a hell of a time bring a gun across the boarder. On the other hand I live in the great USA where I am licensed and do carry a gun. I do not feel in any danger from his threat, had he slipped any info to me.TomC
PS Who are you referring to from New Zealand? And Chris Seymour is a name out of the past for me— what is he doing?

I sure like using bits and pieces that are just laying around the shop… no additional welding required… as soon as some silicone hardens and Rich finds me a chunk of 1 1/2 hose I can give it a go…

Hey Rich!! Get that piece of hose over here. I want to see this thing work. I have no idea what it is but I think I see a horizontal cyclone and a cooling rack What is in the tanks, few people know.TomC
