Wood Gasification Stove

[Battle Creek Knives]

I'm sure this has been covered numerous times but thought I'd post up my first wood stove. I called my local Sherwin Williams paint store turns out they gave me 2 quart cans for free cuz they didn't have lids.. The rest of the stuff I had so the stove cost me ZERO dollars and is close to the bushman stove that sells for $100.... well this stove is close enough for me anyhow

Here's the whole mess..

Stove together

Ignition

Gas..

10 minutes to boil 16oz of water, it was 32 degrees outside

Still burning after 20minutes, of course I was adding wood while boiling water..

Conclusion, there are some improvement to make it better, first my pot stand needs more holes. the chicken wire has to go and I really only used it to test stove, I have a little bit of diamond lathe laying around somewhere I'll use..

the biggest problem I had is, I wasn't prepared with enough sticks and had to scrounge around for more as the fire starting dying before the boil, next attempt I will be prepared.. I'm curious to see how fast I can get 16oz to boil with this stove..

all and all it was a simple process and I was fortunate to have the materials on hand, and the progresso soup was delicious btw..

Very Nicely Done! I've got a collapsible wood stove on order that I can't wait to get!

nice i just built mine on thursday...no pics yet...i ran into the same fuel problem...looks nice and clean....how was the smoke output and soot?

 

[Battle Creek Knives]

lots of smoke, I used some pieces even had bark, bark cedar, and it was the first burn so maybe that contributed IDK..

I'll prep again with just twigs etc and and see how that goes.. matter of fact I'll go out and do it now..

ETA: I just got a burn time of 8 mins with 16oz of water.. no where near as much smoke this time.. mainly used slivers of oak and twigs..

it would be interesting to hear other burn times with similar stove..

Looks like you used the same plans I did.

FYI, if you keep the fuel level below the top row of holes in the can you will get almost no smoke and equally little soot. The tendency is to want to load it up because it burns fast, but if you cut your sticks shorter and feed them in one at a time you can eliminate most if not all smoke (I usually burn cedar and bark).

I also do not use any screen inside my can (it seems to work fine without the screen/grate, so I tossed it to make more room for fuel).

YMMV.

 

[Battle Creek Knives]

Unit I'll have to try it without the screen,my biggest concern was wood or ash plugging the holes from down draft. hey if you get a chance maybe you can see how long yours takes to boil 16oz water.. ??

yeah I seen someone post there's on bcusa, that's where I got it..

I know this is an old thread, but the question asked here has not been answered.

One poster was a little dismayed that the wood burned too fast to complete a boil. I too have found this can happen. Especially when dry, real dry wood is used. This past month I used my own version of the quart paint can gasifier and for the first time was able to make 2 pots of coffee without filling or adding to the original fuel. Here's what I found:

When selecting available fuels look at the limbs low on a tree that are NEAR crisp and twiggy. A little green is preferred, it burned slower and considerably longer. Today to test my theory- I am building more stoves for gifts, I used Cherry Smoking Chips. The fuels was so dry that I never got one boil in.

The lower twigs I used were from conifers- Doug or pine. They were exactly what most use for kindling; just a touch of green left. When you find the right stuff, make a mental note, or better still write it down and store the info in your stove for next use.

I've been messing with those for a couple of years. Even made 27 of them for the wilderness camp that I do with middle schoolers in the summer. I found (and have written down somewhere) what I found to be the optimum size and number of holes on both cans to get the most efficient burn. With my final can I can pretty much get no smoke and a full boil off a nalgene bottle from one can full of fuel.

The diamond lathe will work much better. They are fun to mess around with but aren't nearly as convenient as the ember lit stove I broke down and bought.

Here's a stove I made a few years back out of a double walled ice bucket I pulled out of a dumpster. Works like a champ nd I have cooked many meals on it. I've burned pine and eucalyptus in it. As long as it's not to full I get a good flow of air and it is so efficient it is almost smoke free.
