Prof. Shafer! Imagine my surprise when I discovered your channel by accident when looking for a charcoal retort design. It's good to see your project going well.
After 2 years, my only suggestion would be to just place your chimney on the top of the barrel and trace the circle around it, and to drench the burning biochar when the flames are just barely above the biochar. That is the perfect timing of when to shut it off.
I made this burner and used it to burn sticks stripped by goat cut to barrel length and packed tightly with wood chips filling the empty spaces. I neglected to dowse and it all burned to a small amount of ash. I'm about to try again. Not sure if I should damper it of this time somehow after ignition because my last firing burned so furiously.
i don't think u emphasized enough the importance of dry feedstock if your feed stock isn' tdry enough you end up with a smoldering mess. speaking from experience
I don't know anyone who has access to these specialized tools. The barrel might be easy to obtain for someone with lots of privilege, but the only piece of this equipment that I can get hold of is the string...
Stay positive, do not let the challenges stop your great mission. Angle grinder from Harbor Freight tool is $9.99 to $20 depends on sales or not, a 4" grinder disc is $1 each, steel barrel can be bought looking into local ads, like craigslist, about $20-40 per. Now do not complain, just do it.
also, check if in your area there is a tool library - they are growing in popularity. Just put the call out for someone to lend you one - especially as it is for a good cause! Good luck
Good. We keep all good things from dorks like you that can't scrounge up a few bucks and a free barrel. Don't even bother to think you could borrow the tools either. No one would lend them to you! Your sad sack would steal them.
There is quit a bit of talk about Metal fume fever. Exposure usually arises through hot metalworking processes, such as smelting and casting of zinc alloys, welding of galvanized metals, brazing, or soldering. If the metal concerned is particularly high-risk, the residue from cold sanding processes may also cause fume fever, even if the dose is lower. Occurs by inhaling metal oxide fumes that injure the lung. Prevention of metal fume fever in workers who are at risk (such as welders) involves avoidance of direct contact with potentially toxic fumes, improved engineering controls (exhaust ventilation systems)...
I would add some informations: the barrel steel must be rust-ressistand, if not it will crumble after 4 use... use smaller barel as char-generator inside the bigger that work as stove and burn until ash. everything inside should be fried to the crisp. After one hour. Do not open, and wait until you can touch the can. For safety reasons because water can...explode... Now mix with the soil in one to 10 or one to 6 for grass plants.
When you burn until ash you get ash, not biochar. That misses the whole point. Ash is very alkaline and produces no homes for microbes. It is no longer biochar.
@@johns7713 This is WHY the oxygen should be shut-off from the barrel inside that is burning volatile pyrolise products. It work. P.S. Because bochar is alcaline and without nitrogen, you need to pee on it. Wastewater is enough. Then put to the ground.
Are you kidding me, cool drill bit, go buy a made in America, or Europe drill bill, might need to go to a industrial supply, as machinists do. Buy quality.
This is such a clear, concise, and descriptive tutorial. All of TH-cam should be this good!
I built this today. it worked. great char. total cost. 13 bucks.
Hey, have you made bio char from wood in this kiln too?
Is that ok if i put bamboo and make it as biochar?
Prof. Shafer! Imagine my surprise when I discovered your channel by accident when looking for a charcoal retort design. It's good to see your project going well.
Excellent description. Detailed and no nonsense.
Simple design, very well narrated. Good job. I will definitely try this. 👍
awesome way to use a piece of string
This is a fantastic video! I wish I had seen it a long time ago! I am going to make biochar this year. Thanks for making everything so clear.
JOhn
Your attitude prolly made a great atmosphere in your work environment.
what do you mean by waste feed stock? Can I also use wood?
Interesting. Someone has asked me to build one using waste wood from a cabinet shop. Going to look at more designs. Thanks for sharing.
After 2 years, my only suggestion would be to just place your chimney on the top of the barrel and trace the circle around it, and to drench the burning biochar when the flames are just barely above the biochar. That is the perfect timing of when to shut it off.
excellent tutorial and great fabrication tips and tricks
How does it stop flies??
I made this burner and used it to burn sticks stripped by goat cut to barrel length and packed tightly with wood chips filling the empty spaces. I neglected to dowse and it all burned to a small amount of ash. I'm about to try again. Not sure if I should damper it of this time somehow after ignition because my last firing burned so furiously.
Can you burn woodchips and other forest 'residues' with this biochar machine?
Yes, as long as it is not too big a piece, I had done 2x4 left over, just take a bit longer.
I've done it with pine wood with a variety of sizes mostly offcuts. It was difficult to say when it was done. Took a good few hours to burn down
I'm slow. I don't have access to cob. But branches. Same deal?
What about for rice husks
thank you sir.
How does this instrument fulfil the criteria of pyrolysis?
That is exactly pyrolysis, of course..... I have seen a lot of various design, this happens to be the MOST simplest one easiest to make~!
Can we use poultry manure in this machine?
Genius design
Seems you would get to much air. Guess if you let it go to long, it would go to ash. How long did it take?
Can i make coconut chacoal like this sir
Barrel will last about 12 burns.
Fantastic!
Thank you very much.
Cool
I built and used but turns into ash instead of bio char where did I go wrong
Your roof sheeting is zinc plated and is exposed to open flame. Isn't burning zinc coated materials dangerous or poisonous?
If you inhale the fumes you get metal fume fever: en.wikipedia.org/wiki/Metal_fume_fever
its all rust. I don't see any zinc.
Zinc is an essential nutrient, a little of it will actually do good.
Not in your lungs.
See other posts.
Welders have to deal with this all the time, and they can’t take zinc poisoning!
@@NwoDispatcher Probably a bit on the ends, but yeah it seems predominantly gone.
A piece of 5/8th inch Boilerplate under the rig is a nice touch, if you live in areas with a Loamy Soil.
Yes, Virginia, Dirt can catch on fire.
great explanation here: Following
i don't think u emphasized enough the importance of dry feedstock if your feed stock isn' tdry enough you end up with a smoldering mess. speaking from experience
Yes. I could have saved some TH-cam time if the video began with 'Remember ; Waste Food Stocks Only !' rather than leaving it to the last minute . ;)
Can grass clippings be used as feed stock? If so, it needs to be dried first right?
not productive to put grass in, how much char you are going to have left? all burnt to ashes!
I don't know anyone who has access to these specialized tools. The barrel might be easy to obtain for someone with lots of privilege, but the only piece of this equipment that I can get hold of is the string...

When you think it's dead, dump it. I don't know why I found this funny 😅
Wow
why wastes feed stocks only?
It's not anything to do with the quality of the char. I think he's just trying to give environmentally friendly advice.

With string, I thought I was back in ancient Egypt from my past life!
You waste the biogas .

Kruezifix!Gibs dös ah?
Can two girls make this also? ;)
Tillon Sara jes no problem
corrosion x and drink from the same cup XD
u just need one sexy girl to do all these or more...coz all the guys will do it for her for free.
2 girls 1 barrel
🇲🇦
Not an efficient design.
Can you link a better design please? I'm doing yt research on these would much appreciate :)
