    Default Ever built a rocket stove?

    The rocketstove is an amazing little device, and it gets hot as heck with very little wood. Hobo's and people in impoverished country's have been using them for years. They are so simple to make, it's not even funny! I built one, and it will heat water and cook like a champ. There are all kinds of designs and instructions on the internet, but basically you only need 2 tin cans to build a simple temporary rocket stove!

    That is a great article in Solar Cookers World Network. I have been fiddling around with brick versions covered with adobe on and off for a few years.

    HEre is a link to the article.

    I have been working on heavy steel version for weeks. I'll try and get some pics up soon. Thanks for the post. I have some revisions to do to the design after reading this.

    Stick with me, Karl. You never know where my mind is going to wander. Pull up a chair next to me and we'll both watch.

    Add a shelf to your feed chamber.....wood on top.....air intake on bottom. That's what makes them so efficient. Also beware that if you don't add an insulating layer and outer (or make and inner flu) cover that metal is going to get reeeeeeeeeeeal hot.

    I plan to add the shelf to feed it. It is .134" thick to handle the heat, certainly not a coffee can.

    I know it's thick. That wasn't my concern - getting anything or anyone too close to it was.

    I agree that is a concern...not sure how a fully insulated stove would heat a camp? it will get hot...it goes without saying, don't touch it.

    Having read up on the rocket stove. I guess that is really not what I built. Guess I have kind of hybrid between a rocket and a hobo. I'll add the shelf today and try that and see how it goes.

    Test Burn, used (2) 2 1/2" pipes with a plate of steel on top for the air intake for the test. So, yes it neds an air intake, I think smaller than what I used, though I could see a difference blocking the intake. I'll weld a shelf in at 1 1/2" The wood I used was barely dry (stuff that I had mowed down with the bush hawg) It'll make a great little stove for the boat for Hawg Hunting (We may get to go in January) A cleanout would make a nice addition as well. The "camp" fire I had beside it used 5+ times the wood in same amount of time with a negligeable difference in heat being put out. This was with softwood in the stove and hardwood in the "camp" fire.

    I thought it would prove difficult to light, but using just a couple of slivers of fatwood it lit right up. I had gathered a jacket pocket full of fatwood and didn't need but a few slivers the draft pulls the flame upwards, you get a good complete burn, not like a true Rocket Stove but the concept still helps.

    Nice build, it looks like you are on the right track.

    If you build the stove with an insulated double wall around the heating chamber, it gets even hotter, and it keeps the outside cooler to prevent burns. I am having a 304 stainless steel elbow fabricated for my next rocket stove because when you insulate them, the elbow area gets super hot and will melt plain steel after time. But the 304 SS will take a consistant 1200 degrees without deteriorating.
    It is fun to experiment with these stoves!

    You actually have 2 cooking surfaces with this version since you used a box version rather than a cylinder.
    basically a burner, and a warmer. depends on how hot each surface gets, both could be used as a burner.
