you're drawing too much air from your feed point opening for proper pyrolysis to occur, and overdrafting your combustion chamber... to much air=low pyrolysis... think of it this way... the ambient air is 80% nitrogen and around 19%oxygen, the nitrogen doesn't help you any and all you need is the bonded oxygen O2, so with too much intake of ambient air the Nitrogen damnpens your combustion... we need to find a happy medium from raw air intake in volume to efficient pyrolysis I know you have problems with bridging and whatever about your feedstock, but then your condensation loop seems to be capturing the moisture and the garbage so that's good news do you have any way of making venturi along the sides of the CC to create a vortex ?

Love it, trying to figure out how to make straight holes in my future workbench. BTW - Have you considered making a flat face on the protruding part of the bench dogs? It might help reduce denting in the supported woods. A piece of cork rubber could even eliminate it completely and increase holding friction. And if it's only one side - if not needed, just twist it 180°.

No!

No!

That's a nice setup. Although it doesn't have to be near as big. You can get quite a bit of hydrogen gas from just a small amount of charcoal/wood chips if you get it really hot with air flow. You don't need a large mass of hot carbon. You just need a small area that you can force all incoming air through. It will run much hotter and will crack the tar. All you will have is Ash and no tar or moisture. Remember the wood / charcoal does not contain the fuel that you're wanting to produce. It produces glowing carbon to convert all incoming air to hydrogen and carbon monoxide

The actually taste great, 10 times better then kangaroo. But you didn't hear that from me 😊

That's a hell of a roar.

What is it? Would it eat you if you turned your back?

The doors look amazing. Truly beautiful. In my motherland in europe, green was a common colour to have on garage doors, garage gates, storage sheds etc. when i was a kid. It’s nice isn’t it? Today everything is white grey or black. 🤷‍♂️

You are definitely impressive and for you a gasifier is a must have, with all the fuel. I would prolly get an industrial type wood shredder, because that's real close to being the best size to not introduce much bridging. A drying table is nice with an overhead electric dryer, that you'll be able to run soon enough from your gasifier to generator, right? So I started with E1, then E2, then saw E1.5 and went ahead and watched. What size material did you use for your welding table? 30x80x2.5?

23:35 Wow! no tar. I really want to learn how to build this the right way. Mine is like a tar generator and do not produce flame. What did I miss?

It's unsettling to see you weld something up with no prospect of having to tear it apart in a week. 😁

Nice solution handy to be able to wheel out the way when finished. Tidy work closing off the box section ends looks better than a trolly you would expect to be sold with the unit. That’s becoming a very modular workshop.

👍

This is helpful thankyou

Thank you for your videos, which really keep me on the edge of my seat. I'm also inspired by your attention to detail, your precise, clean, and structured way of working. Here’s a thought regarding potential contamination in your excellent condenser solution. The small stones in your tar-cleaning condenser should be chemically inert, thermally stable, and resistant to wear to prevent gas stream contamination and to support tar removal. Could you clarify exactly which type of rock you are using? Based on my rusty English skills and your explanation, I recall that you may have sourced the nearest available stones from the hardware store or those lying around your house. My suggestions for suitable materials are: Quartz, Basalt, Granite: Stable, non-reactive, and heat-resistant, but a bit hard to source. Firebricks (Chamotte) and Corundum (Aluminum oxide): Fire-resistant and chemically stable, though quite expensive. Pumice and Zeolite: Porous stones that offer a large surface area, which improves tar adsorption. You should avoid stones like limestone or pyrite-bearing rocks, as they can release CO₂, sulfur, or other contaminants that may reduce the quality of the producer gas and affect combustion. I would very much appreciate hearing your thoughts on this consideration. Thank you for providing feedback in one of your highly insightful analyses. Best regards from Switzerland.Dieter Schneider

Are you gonna have plans and parts list?

Edisons... Ugh! The biggest landfill importer after ALDI. Thanks, that's all I needed to know. I don't even care if this is a glowing review. I paused the video after hearing that. I came here because someone is selling one on FB Marketplace. Edisons crap is so bad they've had to change names several times to keep sales up from the avalanche of bad reviews, but lucky for them, ebay now protects bad sellers (which is also why ebay is failing). There's a customer review site I forget the name of... and it's full of angry purchasers of all different kinds of products of theirs. Why people don't wipe their mouse over product names and models then right-click their mouse and spend 30 seconds reading some google links is beyond me.

I tend to favour the Water drip/steam as the oxygen in the water coverts any licker products a stable flair increasing a stable flair, & when running an engine diverting a little excuse to will control the heat stabilizing the gas Production A mix of wood & charcoal is best. you are a step away from. Getting what you have built to work. So I think it is time I tell you of my secret font of knowledge. I was born off the grid in 1952, In 1963 I discovered that a wood gasifier I was using from my dad's old truck predust damp smock in wet & cold winters. & I thought that the gas was of poor quality, so I began to sever excrement's, my answer was to build a caracole colom on to the side of the vestal that was filed with charcoal. when lit i fed the damp smock into the colom & fasten the scion of the filer to the blower & flair the resulting gas now being supplied with air & smock laden whit damp H2/O including the C2 from the air intake gave me C3H4 . Very good snitch gas & just for a pint of focus propane is , "C3H8" So that is why I suggested you drip water on to a hot plat & it will flash to steam & as it is capered into the charcoal will grad it to for C2 & the hydrogen will be set free . But it must be a vacuum & a drip not a torrent. Les the Uk.

try the water drip onto a bit of hot plate as an experiment to see what happens. Les England. you will be surprised. all that licker you have just drained of lost fuel production hydrogen not converted , dip that in to the chamber to flash to stem & you hydrogen will rocket .up

drop back into one blower Ok try dripping in some water the Will fix it. you not get in suffice oxygen in to the blower dipping water on to an hot plat so it can flash to steam will fix that .

cut the fan down a bit blowing ti out

Excellent press brake. We shared this video on our homemade tool forum last week 😎

Excellent work. We shared this video on our homemade tool forum last week 😎

Enjoyed your video and subscribed 👍

13:20 If you blocked off some of those holes to alter the are fuel ratio, I reckon the flame would remain. I am thinking of setting the flame on the oxytorch? Firstly I dont quite know how this is supposed to work but I gather that you require a vacuum, if so, that valve in the top plate will let air in even if it keeps pressure in, it won't hold a vacuum. I may have this arse a peak but I thought I would mention it.

Keep on Mate, respect and admiration!

Awesome thx for this video!

You make excellent videos! Happy to be able to follow along!

I watched you put down three paving blocks and I'm exhausted. What a job that must have been!

Just started following you. Nice shop and good job on the hand wheels! Did you attempt to check for air leaks on your hatch? My understanding is that the air seal is very important. I starting to look into gasifiers (that is how I found you) and would like to better understand the designs and math behind them. Don't know if you are working of a plan, calculated your own plan or are just winging it. Regardless, your work is first rate. I really like your driveway. Look forward to the next video.

I'm so happy this project continues! Keep the good work up!

Today it's just a bloody handle When the project is done it's the satisfaction of I took the time to make it just the way I wanted it. The value of being self made man is priceless

Moving on nicely. And congrats on the plasma cutter. I love your shop and all the tools you have. Would really love to achieve the same.

Moving Forward 👍step by step 😉

That's some mighty fine work, right there :) . You do realise that all this shiny goodness might get a little dirty, once you set fire to it, right? Nice to see that you have invested in a plasma cutter. I got one last year, but I haven't had the time to get it out of its box, and blast my way though the bank vault door with it, yet. Maybe, it will end up as part of a CNC plasma cutter project..... The possibilities are endless :) .

Hi. Very helpful video. I am thinking of buying one of these for an unusual purpose. I'm building a house and are looking to slice largish TeaTree into 2cm "discs" to make a parquetry floor (embedded in resin). I've already prototyped, etc and it works well. The key has been how to efficiently cut and produce a large quantity of these. So my question is a) more generally, do you think this might work ok if I rig up a 2cm stop to the right of the saw blade and b) is the cut fine enough to give a good finish? After that, I will probably use it for firewood.

hello Nice job ! i have never experiment stone condenser, How much time can you keep enough cold the condenser ?

hello, you should take a look to my last trial , a no tar gasifier ruclips.net/video/Bi02trhuAgU/видео.html

Do you have an exploded picture of the machine? Can you share it?

I think you need more fuel less air becouse now it is working as a fireplace and produce only CO2 and H2O. There is no place for pirolysis inside.

Hi, keybord proffesor here, and my 2 cent :) remove the coal bed agetator and replace it with a shaker the grate can hang from chains, if you do that the distance from feed hopper too grate is still a little short (but hard to see so dunno). Cracking tar takes more then 900c in there, a pro setup for that would be a plasma torch in the pipe b4 the condensation/cooling pipe. You are getting way to much cold air in there the way you fire it with the top open, pipe air in, in a way where it gets heated befor reaching the glowbed, a circle or two of 2" pipe in the bottom chaimer going up and into the feed hopper, letting the hot air out in the center of the feed hopper, feeding hot air to the coals. Love the thing and wish I had the means to built it.

how ya going , good vid unfortunately i haven't even got to the point of a spark yet , brought a Rossi 300amp mig/tig/mma/fluxcore/gas get up $380 , got a weld from the stick welder part of it but nothing out of the mig side of things. changed it to flux core under the bonnet, cleaned the steel for good earth , switched to mig on machine light lights up and hand piece tightened on machine although a bit wobbly for my liking , so i tried hitting the trigger with wire on the steel and wobbling the connector but still nothing any ideas mate cheers

Lookin' good :) . I am longing for the day when I move all of my machinery to my new workshop, just like you did with yours. On the dyna bolt thing, I use the breeze from the electric drill to blow all the dust out of the hole, before trying to put the bolt in. Yup, I learned that lesson the hard way!

good day. I really liked your gasifier. Can you give me the drawings? I would like to make one for myself.

I'v had several of these over the years, and they were all sold off in auctions. I i missed them that much that i ended up recently buying the Hafco BS-6V Portable Swivel Head Metal Cutting Band Saw. I made a stand for it to sit on at a comfortable hight with locking swivel casters. But the only thing is with this model it has no auto shut off after material is cut, and no down feed pressure, you have to do it by feel which is ok if your only cutting a few pieces.. I do intend to modify this saw in the future to fix what should have been made standard.

how are you filtering the gas? We have 4 huge wood gasifiers. Running since 12 years. The biggest is making about 200kW The biggest problem in our systems is the lifetime of the filters.

Good job. I admire your attempts and problem solving. You keep moving forward. Unfortunately, I stopped trying - lack of funds. You can't imagine how many common points our projects have. I would like to support you with some comments; 1. Use wood pellets instead of wood chips. You will eliminate many mechanical problems resulting from the use of wood chips. After achieving stable operation of the pellet generator, you can return to wood chips and optimize the generator's operation in this respect. 2. Consider the thermal insulation of the generator heart. This is crucial. I recommend using vermiculite or a similar board (resistant to temperatures of at least 1,100 degrees Celsius) that will be in direct contact with the fire. This direct contact eliminates the problems of steel at high temperatures. Unfortunately, this requires design changes. Ceramic fiber insulation can also be used (minor design changes). 3. I admire your ability to join metals, but it is equally important to control and monitor process parameters. Without process control automation (at least PLC with sensors), success may be incomplete. Regards form Poland

Really appreciate your work. Wood gas creates a couple acids which eat the pyrolysis cores at the bottom neck. Do you think it would be a good idea to go through the expense of getting the core ceremic coated like is done with high-end automotive heads & pistons? Thanks again.
