Instead of a pellet hopper, you should add a larger box for full sized rounds, they burn hotter and slower than small kindling or pellets. Also if you further insulate the riser and burn tunnel your Temps will increase dramatically. A large 55 gallon drum on the feed side would allow full rounds of wood to be added while still causing the fire to burn down into the burn tunnel. If you incised the whole thing in grave, mud, or clay you'd have more insulation at a low or negligible cost. Great videos keep up the good work!
also, if you can pre-heat the intake air by feeding it through the jacket at some point, that can concentrate the thermal energy..
@@yellowajah how would that matter
I am not entirely sure how I got here but I am glad I ended up here. Your videos are really interesting to watch
good ideas, concise explanations, tight editing - love it. metric conversions are also very appreciated. hope your channel blows up soon and we'll see some colin furze scale projects here
There's no stopping you now!
Found your channel the other day, probably because i was looking at wood stoves. Your DIY resourcefulness is mighty impressive, and that rocket stove is phenomenal! When you said pellet hopper all I could envision was a world record speed for cooking a pizza for some reason...lol.
Maybe you kan make a 2 way chimney ,like a ( Y) type & a valve so you can choose in which chimney the heat goes .
In the first chimney you got the heat exchanger & the other is the by pass .
So now you can choose when warm water and when not with the valve .
I hope you understand it .
Greetings from 🇳🇱 Amsterdam ( the Netherlands)👋
I'll often hesitate on a 20 minute video, but 10 minutes is nothing. I'll always stop for one when I know it's interesting subject matter. Keep up the all meat and no filler vids ... I'm loving this diet.
I really appreciate your use of proper safety gear!
Thorough research and application. Professional fabrication. Superb content.
Good golly you are prolific! Great to see that secondary air mod.
When your channel blows up and you’re swimming in fame and fortune, don’t forget about me!
I want VIP access to the success party!
😂😂😂😂😂
Glad to see how dedicated you are on this project. Some thoughts:
1. If you want to be able to use this 100% indoors, you can avoid dealing with smoke by starting off burning something that doesn't give off any noxious products, like methanol/ethanol/propane/natural gas/etc. in order to get the secondary combustion chamber up to temp.
2. Commercial pellets work great for this kind of use, but you can also put regular wood through a wood chipper/grinder to create small, uniform chunks.
3. If you add a 'chimney oven'--or w/e--to some point, you can use the residual heat to dry out your fuel, which will allow it to burn hotter.
4. I would put the forge port at the top of the secondary burn chamber to ensure more even heating.
5. Adding a shutter to each forge vent would allow for minimizing heat loss by limiting the opening to the size of the workpiece.
6. How about trying a small air chamber above the SCC to preheat the air for the air intake, so it would already be super-hot before it entered the stove?
Cheers!
You are pumping out the updates! I love this!
Glad to be here again! You ROCK man!!
Very cool. I love the idea of a even more efficient wood stove.
Adding catalysts to get burn the soot might be the next leap
Nice mods! The forge mod is brilliant, beeing able to use wood in stead of store bought fuel (or spending extra time making charcoal) to forge small projects is huge!
As always, very nice editing too.
I'm new here, but I love your content! Fellow fabricator, and hot metal hammerer guy.
Great stuff. Keep up the good work. We're all learning from your experiments.
Awesome series. I’m glad I tripped across this channel.
Super cool and interesting as always!
I love this kind of advanced backyard science. Thanks for the series so far.
So impressive, Brother
Impressive results!
Make your videos at least 10 minutes long. That's where the RUclips money is. Commercials suck don't get me wrong, but we all know that's how you get paid. I myself let commercials play from creators i like watching. That's my pro tip for you. Absolute bare minimum length 10mins. Helps the algorithm. But more so helps your pocket. Don't forget to put, hopefully smaller commercials in your video. 😊
I say give up on the flue effect and put a blower on the air. Then you could have better control and be able to have a bigger opening to forge with.
I think you'd be right if the goal was to build a straight up forge. might have to build another mod
Legend!
hell yes brother!
Steam locomotives usually use gently curved pipes and angles instead of sharp changes and 90 degrees corners. It reduces turbulence causing the steam to conduct to surfaces and cool. While I’m not sure if this would be better for the stove to keep a laminar flow, keeping more heat in the gasses instead of the chamber walls, or making it turbulent increasing combustion I think it’s something your next stove should consider.
I've really enjoyed this series. I look forward to seeing it scaled up to use wood more reasonably
So cool!
Fantastic so much to learn from each of your videos Amazing results thank you loved the video.
Exceptional work. You actually made the greatest point yourself: "What application can make use of that intense heat?" - and that has me asking and hoping others chime in. I am wondering if you are able to expand the access to forge large pieces as that would be fantastic. Would a cob addition around that area help stabilise the temps? I am wondering how to might activate a type of water battery for heat access later on. As you know, water takes longer to heat/cool than air. So, how do we put that magic to use?
Sand battery?
This is awesome!
very interesting, thank you 👍
I think that it's generally better space heating (especially for radiative emissions) if the heat source is a BIG WARM thing, instead of a TINY WHITE HOT thing.
By way of example to make the point clear, an acetylene torch puts out a lot of energy, but it would be a suboptimal space heater.
Taking to extremes, a tiny little object glowing with 3 kW of heat would be tens of thousands of degrees and emitting dangerous UV (excuse the hyperbole).
Conversely, if the entire room surface was pleasantly warm, then you're done.
Oftentimes, TINY VERY HOT things are enveloped to provide a BIG WARM surface area before calling them a space heater.
If you can design it to transfer most of the heat to an air flow (perhaps a convection channel), then it becomes an air heater and you can bypass the above point.
I agree theoretically. But a competing issue is that for wood to burn as cleanly and efficiently as possible it needs to burn very hot. So then the issue is how to efficiently use that much heat all at once. Aomething like natural gas that burns very cleanly already would be much better at a low, continual heat design.
@@GreenhillForge Yep, good points. So for space heating, get some convection channels on the hot surfaces. Same principle as the rocket stove, just for room air on the outside.
P.S. Thanks for the very nice videos They're great.
Put a turbo on that
I had thought it would be cool to build a rocket stove that can take entire logs of any length you would want. This stove looks like it would do what I was thinking. Just place the entire log tip first into the intake and let it gravity feed into the chamber as the tip burns away.
The only mod I can think of right now is that valve to decrease the flow into the first chamber. It would reduce the temperature but it might decrease the fuel consumption a lot more. The extra air after the first chamber would still burn up all the produced gases. You would be sort of producing gas more than burning in the first chamber.
Awesome
I would see the uses for an emergency forge setup however once you reach forging temps the box will start to melt alongside the metal to be forged. In fact being mild steel I think the stove will suffer more damage than what you're making. It may work if you go over to a fire brick & masonry style stove.
If you watch the video with the original rocket stove build I go over stuff like this. Steel is easier and faster to prototype with and do tests, but once a design is settled on it would definitely need to be built of fire brick, refractory cement, etc.
Put some red lipstick on it, and shovel hundred dollar bills at it, that keeps the heat up! 👍😃 It worked great on my ex girlfriend, until you run low on the hundreds! 😬
Have you tried burning anything else like charcoal in this? I wonder what that would do for the forge aspect and whether you could get it to work with part charcoal part wood.
Oh, if you haven't come across it yet, take a look at Little Aussie Rockets on here - he's got quite a few rocket stove builds and experiments in his older videos.
Yeah, I need to make a batch of charcoal soon anyway so I'll give that a try.
@@GreenhillForge build a heat bell off the top of your rocket riser, then cook your charcoal in a retort inside that bell 😊
Found your channel a few videos back and as most commenters are saying here, format and content are fantastic…..but something kept niggling away at me every time you shot footage outdoors….the scenery didn’t match your accent…the landscape, the stone workshop structure itself, the whitewashed wall behind the woodpile…all familiar echoes to me…I’m a Brit living in the US, btw. Then I finally saw it…the power outlet on the wall behind your metal work table. Now it all makes sense…you’re in the UK. Keep it up, especially the near full coverage format but ‘sped up on the repetitive parts’. Very very watchable.
Cool 👍
Can you do a run with the air injection pipes blocked off, but with the new front intake open?
Also it may be worth adding a curved section to smoothly transition from the firebox to the stack. You are likely getting some significant turbulence in that bottom corner.
I just had a crazy thought to bury your heater in sand surrounded by a steel box with glycol tubes running throughout to heat water water and make a sand battery or something like that? What do you think of the idea?
I don't even own a welder so I will have to live my crazy thoughts thru you... ; )
It's a really interesting idea. you're combining realli efficient parts of like 3 or 4 different thermal mass heating concepts. Not entirely sold on using a highly flammable liquid as the heat-transfer fluid but I like where you're going. 🔥💥😅🔥
@@GreenhillForge Your right, I would have blown myself up! Appreciate the response and your great ideas!
sweeeeet!!
some great and usefull mods - well done - I'd be very interested to know if you forced air via a blower into the secondary air feeds if the extra O2 would increase temps at the forging zone, or the volume of increased air would cool the flame?
I think forced air would increase temps a lot but fuel consumed would also go up a lot
By capping the to you have essentially built a batch box rocket stove
found your channel recently, great videos! Could adding a fan to blow air down the pipes make it burn hotter?
forced air would definitely get the heat up. might have to try that.
What happened under the bandage?
What about lining the inside with refractory cement to increase durability?
Absolutely. My goal is to finalize a design in steel because it much easier to iterate and modify and once I have a final deisgn I really like I'd then build a really solid version in refractory cement.
Does the forge mod allow the steel to get hot enough to forge weld? Or just enough to make it pliable?
2100f is hot enough to weld. whether the steel would get that hot, I kinda doubt it. maybe with some tweaking. charcoal would probably boost the temp too
I have an idea for a mod, a steel coil going through them intake tubes that you have there already, and attach a blower, maybe a blow-up bed pump
That's if you needed it hotter anyway, haha 😂
Might try it at the end just see what happens and to melt the thing down
Does this use special wood?
Can i use plastic?
no, this is just larch but any dry wood will work. burn plastic like an incinerator? maybe, can't comment on the legality, toxicity, or envirnomental impact.
I would love to build a rocket stove with a crucible for melting aluminum
That's a really good idea! It's not that but I do have a series coming that I think you'll like.

Hello, thank you for your videos, they are really interesting ! There is a french youtube channel called Barnabé Chaillot, the guy is experimenting all kinds of stuffs. He has a really good design of pellet fed "solderless" rocket stoves and high temperature rocket stove. Also, he has worked on a heat exchanger prototype which looks really efficient. Definitly one of the best channel on youtube in my opinion. You check, it might gives you ideas. Thanks again for you videos :^)
Steam engine! Need lots of heat to go to a water tube boiler.
