Rocket Stove Thermal Oven?

Hi everyone, i'm a newbie to permies.com, actually i'm a wanna-be with permaculture... Am wondering if anyone has used a rocket stove to fuel a baking oven, wanting to design one for my straw bale off-grid home... anyone tried it yet?

Welcome to permies Nancy
I moved your qustion into the stove forum; there's lots of keen wood-burners there! You may well find info if you try searching as well.

Yep, curent discution on another forum.

Thank you Leila, once i realized what i'd done i still couldn't figure out how to correct it, blessings for your kindness... lol, how'd you do it?

Thanks Satamax

Search for rocket oven on the internet, and more specifically at rocketstove.org and bioenergylists.org

You will find many examples. Also, the Justa stove can have a small oven integrated into it, as has been done with some models of the Ecostove/Ecofogon/Ecofogao.

many thanks Andrew, who knew there are so many natural options? obviously folks @ permies.com! lol, so glad to be learning such awesome stuff, not sure i can contain myself, no settle on which things i want to incorporate into my straw bale i am designing, a friend and i are going to take a look at some virgin wooded acreage tomorrow, he's not real into my off-griddedness yet, but i think it's only because he's not been to this forum yet

BTW, tis awesome to meet so many others that indulge their inner pyromaniacs

what ratios does there have to be for the burn tunnel before the reburn barrel (may not be using proper terms here)? my current curiosity is the possibility of putting a brick oven style structure or woodstove oven metal box over the burn tunnel...is there a site or diagram available to study sizes and compare lorena stove vs. rocket stove, etc.

also not sure if i would want to do this inside the straw bale or design a covered outdoor kitchen that can be closed up in winter & left open in summer

Nancy, I have special steward powers
You can't move stuff around, but you can always PM a steward and we'll do it for you.

LOL cool Leila, thanks, i'll remember to pay homage regularly to those with super powers LOL

The one and only rule round here is 'be nice'; no homage required

Burn tunnel should be short, but if you look through the posts here and on the donkey32 forums, others have made ovens that fit on, or are part of the RMH builds.

Nancy,

You could put the stove inside, depending on the local codes. If your climate is very mild, a covered outdoor kitchen could work fine.

Don't confuse the RMH with the Rocket Stove. A Rocket Stove is in the RMH, but the RMH is not the Rocket Stove. The RMH is what it says it is, a rocket mass heater. If you want a rocket cook stove, there are many designs. one of the more popular being the Justa or Ecostove/ecofogon/ecofogao (again, you can easily put a small oven in a Justa stove). The Justa stove is a modification of the Lorena stove which applies rocket design principals. An excellent design manual can be found here:

http://www.rocketstove.org/images/stories/simple-plans-to-build-the-justa-stove-.pdf

This site, http://www.english.ecofogao.com.br/ gives a good idea of what can be done. The video is impressive and might convince someone who is hesitant about cooking with wood in this modern era.

You can integrate an oven into an RMH (I see that Roy Clarke posted about that while I was writing this response). There are also slow cooking ovens integrated into Mennonite/Russian masonry stoves.

For more serious baking, you might want to review this design:

There are also innumerable variations of rocket stove based oven designs, many of them made with cob.

Wow, am sooooo glad i found permies.com, once i find a piece of land dreams will come true, i knew there had to be a way to return to a life without modern utilities, i shoulda been born native american before my idiotic white ancestors came and raped this land with all it's.... n/m i just love nature & need to avoid rants, lol, there are things i appreciate about my irish heritage & therefore intend to call my place "ShamRockHEART" (4 green hearts assembled to form a shamrock will be a common design motif)... now to just decide which stove/oven design will work best & whether to incorporate it inside or outside the main house... Oh this will probably need to be a seperate thread but what can be done about refidgeration?

Ferment vegetables, dig a cellar, use an evapourater for cooling make cheeses, have fresh produce. It used to be done by most people. Where abouts are you looking for land?

i live in the upper East TN area, looking to retire within the next 10-15 years preferably in the woods near the mountains, looking Sunday in the Greene County area but surrounding counties are being considered except for Sullivan they are NOT eco friendly at all

That's what i'd truly like to get back to, before modern 'civilization' which is now driving me insane :bangs head:

Really? 40 years was an elderly person in those "good old days."

See i knew i was already an old lady, lol! But seriously, it makes me feel so much younger to think about living in the woods away from all the rat race now known as society. I've dreamed of it for over 40 years now.

Nancy,
Here is a link to a Rocket Oven we built over a year ago. http://www.youtube.com/watch?v=uR-LqOquLZA We have cooked over 130 pizzas in it, stuffed pumpkins, a 22 pound turkey, scalloped potatoes, numerous pies, rolls, etc. We have also fired it as a kiln 5 times to harden parts for stoves and other ovens. We were in Haiti earlier this year and taught people in a little village how to make the ovens. They are now making and selling their own bread. Good luck. Jon and Flip

Has anyone tried embedding a rocket stove into the body of a cob bread oven?
I've just dismantled the earth oven I built over the summer. It was so smokey! Now I'm imagining rebuilding with a rocket stove core which vents directly underneath a layer of firebricks which have all their corners resting on a 1/3 brick block. I'm thinking it will then vent through a gap in the bricks at the rear of the oven floor then exit through the oven door just as the smoke from a direct wood fired earth oven would.

Does anyone have any experience with this? Can I capture enough heat without the direct radiant heat of an open flame in the baking chamber?

Mark, I would recommend you watch Jon and Flip Anderson's video referenced above. There are quite a few other examples if you do a thorough search.

Thanks Andrew. I did that yesterday just after posting. I'm embarrassed to admit I hadn't read the string through to the bottom. I'd tried to find similar information some time ago with no luck, but I think I was focused on rocket stoves rather than rocket ovens.The Anderson's video is very much what I needed to see, though not identical to what I have in mind.

Thanks to all of you for sharing such valuable information. I'll post some step by step images from my project as it progresses
