Wow!!!

Any reason you didn't have the water go around all 4 sides of the stove's vertical pipe? Just a section of larger diameter square tube, inlet and outlet bungs, and an upper and lower flange to basically create a water jacket.

Very pleasant musac with subtle machining soundtrack complimenting it! Nice!

You now have the best water filter media, which will even remove pesticides and other chemicals

You need to keep the hot pipe from top on an uphill incline to stop the gurgling steam from forming

www.wealddown.co.uk/wp-content/uploads/2020/12/Charcoal-Burning.pdf You might be interested in this. Charcoal production was a significant cottage industry in the UK. It is very well documented, from amateur, home to industrial scales. It gets a good description in one of Arthur Ransome's books (Swallowdale, I think). Charcoal burners were a big part of life in the Lakeland area.

Stephen, where's the link to your shop? Appologies for appearing dumb, but I can't find it.

Excellent video!

I’m thinking, a char chamber in the center of a rocket stove chimney. Possibly direct the flames to 5 or 6 channels between the char chamber and the chimney walls.

I wonder if your the second run , with all hardwood , was actually done pyrolyzing when you shut it down. I think the noticeable difference in weight as compared to the first batch suggests this. That it took longer to cook, and still was maybe not done ,makes sense, wood has BTUs that scale with mass, so hardwood has more BTUs by volume. You could speed the pyrolization by adding a fan, but consider that a long burning clean flame could be used to power an oven, boil water or otherwises harnessed.

Your damper is the most unusual bit of the whole thing. I've never seen one on a Top Lit Up Draft retort . It's hard to imagine most of us backyard bodgers making one well fitted enough to work.

Even if you didn't acheive the perfect charcoal maker, you happen to have created a really nice smokeless fire heater which I bet there is a bigger market for! ❤‍🔥❤‍🔥❤‍🔥

Get yourself a shield welded onto your deburring tool ,, one slip and it's a fortnight off work.

Enjoyed the video , but for me that piano music was way too much 😝😝

Awesome video mate perfectly explained in every way, showing use for each part and your thoughts and feelings towards them makes for a great informed watch 👍🏼 cheers

Connect a 12V LED to that charcoal and see what it does...🙂

Instead of a flap, why didnt you just make a cover for the top of the vent? I made a garden waste burner just like that and most of the time it burns very clean, outer is an lpg gas tank and inner is a fire extinguisher

This is a very interesting design that you have come up with, I'm just sorry it hasn't been as successful as you had hoped. I make biochar using a 44 with a 150mm bore casing up the guts as the fire chimney, around 12 x 12mm holes at the base of the chimney to evacuate the wood gasses. In mine, the 44 is sealed and no air can enter the wood chamber, once pyrolysis commences the chimney temp goes will above 700C, glowing white, roars like a jet with a flame extending around a metre above the top of the exhaust flue which is 900 above the barrel. This continues for around an hour and the resulting charcoal is amazing, the wood volume reduced by around one third. As you discussed, the only issue is the wood vinegar which produces the greyish smoke before pyrolysis starts, but I'm not sure one would ever get rid of this as it is not combustible. Currently have some of the kit to build a bigger system that will take around 300 litres of wood, this time a horizontal design, just wish I had your workshop! I'm in SEQ and I recon it would be good to bounce ideas as we're both in Aus. Good luck with your developments, keen to watch the progress.

Reminds me that with all that off gassing, it could be used in a vehicle gasifier that my old dad used to mention they used, way back.

Yep I was just there for some eggs when I brought one too😂

Great work Stephen looking forward to be one of the first to purchase. Rob

I'm just jealous of all the material you have sitting around to build stuff with. I either have to scavenge little tiny pieces, or pay top dollar for new stuff. Surprised we didn't see the plasma cutter helping out on this.

Boa noite. Gosto bastante do seu trabalho. Assisto tos os seus vídeos. Você é um excelente profissional . Ex excelente pai. Excelente marido. Parabéns !

Now that you can produce charcoal, guess what your next project should be?? Now you need to build a gas producer to run a 1940s truck I am involved with, lol.

How far away are you from making "activated" charcoal?

I've been wanting to build one of these that powers itself from its own wood gas.

From the music I thought i was watching a "Lignum" video, new format is good but so is the old, well done

What I did for monitoring the end moment was to put a crumpled ball of aluminum foil underneath the retort. Once the burn zone was low enough to pass light through the bottom holes, it would reflect across all sorts of angles. I actually watched mine from within the house in the evening about 20m away. Once red started showing, time to stop the burn. Without this, you may have to bend down and look over and over to see when to stop. If you have access to arborist wood chips, they will work in that design as well. But, you don't want to pack them in with any extra effort. Need air to come from the bottom to reach the burn zone. Too tightly packed and the burn will go out. I envy that you have TIG. So fun!

Love it. Fathers dad present in bound

I'm green with envy. had this sort of thing on my mind too...

Shooter is dead. Biden said five days ago that somebody needs to put Trump in the bullseye.

Awesome project. I have started using biochar in the raised bed garden and some large pots.

Have to watch this later. Trump was just hit in the ear from gunshot in Butler, PA.

im thinking of building a conventional block bbq in the back yard but also incorperating a large rocket stove into in to use as a wok burner etc , would u have any ideas on the design and best way to incorperate it into the bbq , thanks i really like your work that pressure cyd stove / hot water system is a beast

Have you thought about using heatsink walls for the flue to increase thermal transfer to water?

You should sell the plans for that welding cart on your store. Couldnt find anything similar anywhere else...

A rocket espresso machine would be nice . 🤪

Don't be scared of upping the frequency even higher. I often run at 200hz on stainless, 33% on, 33% background.

So it's like... light match, wood starts to burn... YES! we have invented FIRE!!! (Bit complicated but I think I got it now)

Cool

1:51 If that was inside the knob on a gearstick it would be the ejector seat so hang on to ya hat. Plasma; The new gas axe? Its thirty years since I sold the farm, would that be category 4 couplings?

Thank you

You get a greater volume of hot water by converting a gas hot water heater and make it into a wood burning hot water heater. Pull off the gas burner and use a small can to contain the fire, and I mean very small fire consisting of a handful of kindling. You’ll be amazed how fast it heats water and a lot of it with just a little kindling.

I couldn’t find any info in the manual about the steel rod is that for steel/stainless steel gas/gassless welding?

I think the other issue you may have is the heat hitting the bottom tube first which is normally the cold return line in a thermo syphon. Maybe a check valve in the bottom line to make the thermo syphon work better.

Noted that you can run a pipeline around the fire box where its red hot . Why waste heat .

terrible vid too many shitty ads
