Glad to hear from you Max; A posting you made struck my interest;
I have gotten in a hurry to get my truck back together, so other than the suggestions you have made for my oxidation/reduction/grate zones, I am putting my truck back together with most of the original design. My cyclone was rusted out so I made a copy of the original. This is about two feet tall. I am thinking of getting more out of the use of that space by using a flatter Thein baffle separator to replace the cyclone, and using the extra height to put a hot bag filter on top of the Thein. Have you gotten to the point with your Thein design/thoughts to share?? TomC
Max; It is colder than the hubs of hell outside so I am going back through old postings. I ran across 636 where you specifically ask for my critic. I apologize for not replying. I had bent a rectangle piece of steel into a circle to sit above my nozzles. After seeing your skizz, I got lost in thought as to how I make a small cone and forgot about it. Am I interested in applying it? I seem to jump onto any new idea that comes around. My new philosophy is to weigh how much improved performance I can get from how much effort I have to put into it. At this point I can reach down in my hopper and pull the ring out that I placed there. Then it will depend on how I can make it as shown in your skizz.
A critic of your post; the explanation was hard to follow and I was not sure what I was envisioning was correct. The skizz was very clear although it lacked explanation of the actual effects. The two together were very clear
Again I apologize for being so late with this. TomC
Hi TOM COLLINS , i Have a questain about your gasifier.due you have a hopper heater, and or due you have a monerator hopper, AND last due you have hopper cooler.i couldent see if you had any of those features.???Thanks for posting your type gasifier.
My build has continually changed over the years. At one time I had a heated hopper and was satisfied with the performance, but I had started with to small of a hopper and when I built the mantel on the inside, I could only get about 25 miles out of a hopper fill-up. When I cut the hopper apart, I learned that you have to be able to clean the soot between the hopper and mantel. It had a big build up of soot. Then I built a hopper something like a WK but I decided that I didn’t want to give up so much space inside the 55 gal drum. I built a gutter down about 15 inches from the top of the hopper and just have one outlet from the gutter. My thought was the upper part of the hopper was the most effective place for condensing water. I have a dome shaped lid and I built a gutter for the condensate to drip off the lid and the gutter directs the water to the gutter on the side of the 55 gal drum. TomC
Hi Tom,
I’ve been the gutter route, too, and it works well. It’s a part of my changes, too. This works well, but my monorator has this one beat by a mile. Geez, if only I had known this first! But it’s all a great experience anyway. This “hopper” is still part of my latest gasifier with the monorator hopper added.
A monorator hopper is on my todo list-- so many people use the word monorater as a generic name for any hopper. I believe it has to be built exactly like your drawing to be a true monorator. Where did you get that rod to make your grill part out of. I had purchased some 1/4 rebar at the cement company some years ago for a project. I went there a week or so ago and they said they didn’t handle it any longer. It would be perfect; it is smooth and looks just like 1/4 inch drill rod, only very cheap. TomC
The rod found its way to my shop via my sweetheart’s auction treasures, a whole bunch of 5’ pieces for a buck. Had no idea then what they were good for and they sat around for a couple of years.
The build isn’t too bad. My grate was a challenge to me and I love the way it turned out
In my experiance the buildup in the void is not bad at all as long as the hopper temp stays low. Buildup stays at about 1/8 of an inch thickness. However heat from running the wood low will bake the tar some. Also the funnel area will need a good cleanout occationally.
I’ll post this here, too. See how I built mine. Go to “Small engines” section. Then scroll to , “My first small engine run” and look at comments #140 thru #170.

JO; I was talking about soot build up in the mantel not the hopper. Max said that if I had read the brochure on the Imbert gasifier it was very clear that you have to clean the mantel at specific times. I didn’t even know there was such a brochure-- especially in English. So it was a surprise to me at the amount of soot build up.TomC ( my woodgas had not gone through the cyclone before it went to the mantel.)
Thats the way it goes when hugging the wood burner weather. I finnally got the full picture of the monerator hopper.Good luck with your truck unit modifications, my heated hopper works good, just that could use a hopper cooler or sorts for wet wood, since i have a place under the truck for a cooler, i may try see how that works some time for tar and water remover.
In going through pictures last night to find the ones where the engine was gummed up, I came across a build that I don’t think I ever posted on DOW.
This one had the mantle around the hopper and my first version of a counter flow air pre-heater. I abandoned it because the hopper was too small to make a trip to like Argos.
That looks neat Tom Collins, you been scinning this cat for a little while.I like the idea of preheat too help rid the excess heat rolling off my rig, along with recovery energy. Many ways too do it finding the lightest way might be our best challenge goal .Thanks for finding that one of a kind build.COOL. THE NICE THING ABOUT THE WAYNE KEITH HEAT EXCHANGER IS IT HAS ONE CLEAN OUT at the bottom and a top too clean once and a great while.
That looks like a good generator test unit or tini pickup if they were not so expensive or rusted out in the snow/rust belt.is it built with imbert air supply dementions.
