- Will this burn using twigs and wood chips? This portion of the Wood Gas Stove Science Series will be devoted to optimizing the beloved Quart Paint Can Wood Gas Stove. I want to make a good stove GREAT!! This is Part 6.

The Wood Gas Stove SCIENCE series is an attempt to learn the science behind and how to optimize wood gas stoves. There are many videos of people drilling random holes in random cans and they are great! I have watched most of them and that is where I got my inspiration for this series. I will not show you how to build one until I have an optimized stove design. I am trying to find the correct ratio of can size, fresh air intake, primary and secondary air ports.
Thanks for watching and please stay tuned for more videos in this series.

This series is very great, I wonder if you can scale it up to like a 5 gallons metal pail for larger pots.
I will move on to larger stoves soon! I want to fully explore and optimize the quart size first. Thanks for the comment!
These are so fun to experiment with. Made one with my Swiss army knife. Works great. Making a bigger tweeked one tonight. Thank you for your time.
Literally watched all the stove videos so far, what a journey
It was funny to see you answer our demands for burning twigs but at the same time cutting them up the same size as wood pellet haha
Burn time and airflow are very dependent on fuel the tighter you can pack in the fuel the better! Thanks for watching!
Well, pellets give a high fuel density, it was to be expected that natural material has worse results. I tend to only use twigs up to the diameter where I can't break them with my bare hands anymore, not larger. Bigger chunks go in first, good shake, smallest on top, helps with lighting.
We did a ton of tests too, and adding fuel should be done early but not right away, and, as you said, slowly, piece by piece
Absolutely! Thanks for watching!
Nice, sir. Your stove runs smoothly.😁 But my stove had a problem when I filled a piece of wood It did not burn fast like your stove and caused an unstable flame in the stove I don't know how to fix it. 😂
Thanks for sharing, sir.
Heath if you are still out there perhaps be interested in the four dog night stove co videos,by the way thank you for the great videos, chapter 1 tin can bushcooker history.perhaps trying to build the better mouse trap or the best of both worlds.
Thanks for the info and for watching!
Another way to stop soot is the let your wood pellets, twigs or whatever you gather soak into denatured alcohol, yellow bottle heet over night. Once the wood is completely drenched in the liquid fuel there should be a beautiful blue flame that is hopefully sootless.
Sort of an alcohol stove using wood as the wick! Thanks!
@@heathputnam9524 Anytime! :)
Ótimo vídeo Parabéns 👍🇧🇷
Obrigado por assistir!
There is a pause at 4 minutes, not sure what happened but the audio resumes in about 25 seconds
maybe an idea for another test:
1. get a branch with a diameter little smaller than the burning chamber diameter.
2. cut to length so it would completely fill the burning chamber depth
3. dry
4. put rubber band around the circumference and split in 8 pieces (kind of like a mini swedish fire log)
leave enauth space for propper airflow and optionally put a bit of tissue paper between the splits and drizzle candle wax ofer it for easy fire starting (idk if methanol alone would light it up propperly)
I think the idea of having a mini swedish fire log inside a wood gas stove would improve airflow inside the chamber since there would be less resistance than with pellets or twigs and maybe the burning time would improve as well since there is not as mush surface area exposed to the flames that way.
I may try that in the paint can stove! Thanks for watching!
@@heathputnam9524 I'm looking forward to it
Great...! So, its not big difference between wood pellet and twigs or wood chips... its advantage where no wood pellet available...thank you...!
Yes I was pleasantly surprised! It appears as long as you find solid dry twigs and sticks and cut them up fine enough to reduce amount of air between them you should get a good burn with plenty of cook time! Thanks for watching!
Cool! Thanks!
But if I am using this stove in the woods, I'm going to want to use it with small sticks that are not cut to imitate pellets (small finger sized, random lengths, short enough to stay beneath the secondary air holes) and without a chemical accelerant. My attempt, so far, will smoke until the secondary air kicks in, then clean up. But burn time is so short that I need to add sticks a couple times to get enough energy to boil 6 cups water for coffee (Stanley coffee pot just fits on to pot stand). I cut out a larger hole in pot stand to add sticks. Added sticks, will, however, ignite well after addition. Some smoke again at the very end.
I used a can about the size of a large chicken/tuna can for pot stand, cutting the bottom to mimic your flame concentrator. What can did you use for your pot stand, since mine is considerably shorter and not achieving your vortex.
I tried to burn the same type of sticks and twigs. What I found was there was too much space between them. Too much air not enough fuel. I then cut up the same sticks into really small pieces and had better results. You may want to try to reduce the number of primary air holes. That will slow the flow of air through the fuel and possibly help with fast fuel consumption. The pot stand I used was crushed tomatoes, Hunts I think. I will try to do some experiments before my vacation. Hopefully get out a video! Thanks for the comment!
@@heathputnam9524 It seemed to need more primary air to get it going at first, possibly because I was using tinder instead of an accelerant.
Restriction of the primary air supply to encourage usage of secondary air supply? Will that happen anyway as ash builds up? Is that partly why the secondary air kicks in later?
Starting with tinder, unless it’s extremely dry, will most likely smoke a little and time a few extra minutes to start but should still start drawing secondary air around 5-6 minutes in.
What is your current primary to secondary air ratio?
@@heathputnam9524 The original 5:1, then opened up secondary air holes to the 1/4". That seemed to give me a better flame. I can try eliminating or blocking the holes on the side of the inner can.
My pot stand/flame concentrator is not optimal - need to find that tomato can, or equivalent. Or two of the large chicken/tuna cans high?
If the primary holes on the sides of the inner can line up with the fresh air intake holes, the wind will cause the burn to be twitchy. I moved all my holes to the bottom. I still have 45 one quarter inch primary holes but they are on the bottom which did help a lot.
Why not cut the twigs with fingernail clippers
Thanks for the comment!
Man, how in the world did you drill that inner cup? Thing is so hard to get through
Lol! Sharp drills!
I love the series and your channel. The only thing that is annoying if you saying "Ahh" and "Umm" every 3 seconds. Maybe try and clean that up but just taking a breath? So, say something, and then when you would say "Ahh" or "Umm" just be silent until you say something else? Great channel
Uum, I'll try to fix that! :)
