Modified worldstove burn test

I modified the design from worldstove.com everythingnice stove and it did very well, you can get the design from their site and I used the paint can with progresso soup can with the dimensions from their biochar design.

The stove started gasifying at 3:20 and then boiled two cups of water at 5:20.

Nice stove. Thanks for being quantitative. I had a question: how long does one 'can' of wood burn for?

@danocarvalho Thanks! About 12 minutes 30 seconds with Maple chips without adding more, it would go for a day or more if you kept feeding twigs into it..until the ashes filled up.

763079 : the smoke is minimized, due to the efficient burning of the wood, which to me is the benefit of this type of stove.

I'm not sure, I would think smaller holes would mean more pressure, but because it's static without a fan...?

I know the other types of stoves that have the bottoms removed I used 1/4" holes and it remained yellow. I am just not sure other than to test it.

Is it feasible to make a stove that burns wood, with a container inside of it that contains wood that is deprived of air so it will create gas that can then escape through a vent to be burnt (and create charcoal in the process)? To me, it seems that size is really the only limiting factor. But the way you are doing it, you really aren't getting much wood gas and have a sooty fire.

How long did that handful of chips burn?

Cut a hole in the middle of the paint can lid to 1/2 its diameter and fit it. The extra heat contained at the top of the stove should draw more air through the top holes. You will get a faster warm up time and a stronger flame (I hope) so that the resins are burnt and more enegy is available to cook by.

i saw one build where a tapered inner container was used, the guy said it built alot of gas pressure he thought was because of the space in between the two containers getting smaller towards the top, u might try that, really nice build btw
