So I'm a wood worker and I produce a LOT of saw dust. I usually just trow it out but I've been searching for uses of sawdust that are meaningful to me. I wanted to use it as a fuel but its hard to burn. Then I came across this: http://www.motherearthnews.com/Do-It...ust-Stove.aspx
So I tried making one. Here are the pics:
Here is the sawdust packed into a #10 can. I drilled a 1.5" or so hole in the bottom, placed inside a tube of caulking that was laying around, packed it full of sawdust and compressed it as tight as I could.
Then I removed the caulking tube:
inside:
I lit a piece of paper and shoved it a few inches into the top. Within a few seconds it took off and started burning the whole length of the hole. Its important to prop up the can(i used wood wedges I had laying around). This allows the air to come through the bottom so it can burn. this is what makes it work.
Within a few minutes it settled down a bit
If done right, these can burn all night long.
Right now its just glowing inside producing plenty of heat and virtually no smoke. I could cook on it easily. Mine was made with some pretty coarse sawdust from a router, so I think its burning faster than finer sawdust might have. Its also pretty tall because its a #10 can as opposed to a paint can. Apparently the taller the stove, the hotter it burns and the fatter it is, the longer it burns. Its been burning about an hour and a half and the stove has burned maybe 40-50% of the sawdust so far. Since I produce about 100 gallons of sawdust a week, I definitely have enough if I wanted to store it and use for emergency heat or for a campfire replacement on camping trips.
I'm going to let it burn out and see how long it lasts. You can add a can on top with a hole cut in it to turn it into a makeshift wood stove that will radiate heat. If you build a chimney in it, it can be burned in an enclosed space(atop something metal) and direct the smoke outside. With some experimenting, I might be able to burn the smoke too like a woodgas stove to produce even more heat and eliminate the smoke.
Enjoy.
