Stove/cooking discussion (split from recruiting forum)

here is an easy one if i uploaded the file correctly. you need 2 metal cans one larger than the other. the smaller inside can should be a little shorter and smaller in diameter to leave a gap for the woodgas. drill some half or five/ eigths holes, about 3 or 4, holes on the outside can on one side only so you can face it away from the wind. take the small can and place it on the top of the big one and trace a circle with a sharpie. drill in center so you can start cutting with tin snips to that line. now you can snugly fit the small can into the large one. before that though, drill some holes about 1/8 inch or so in the very bottom of the inside can, then a few around the bottom just above the lip. woodgas exits thru these and rises up the gap between the two cans. at the top of the inside can cut some 1/2 inch slits so you can fold them down to rest on the larger can when pushed down. about one inch under this lip drill some very tiny holes all the way around as you did at the bottom. you cant see these in the pic. here gas reenters and ignites starving the wood pellets (more dense, last longer , buy at tractor supply) of oxygen and baking them thru pyrolosis. you will have a good cheap stove that will burn for an hour. twigs broken in small pieces collected in the woods works fine. you can always add more from the top dropped down thru the fire. when the fire goes out dowse with water if you want to save the biochar, otherwise the pure carbon you now have will turn to ash as the embers continue to burn. charge it in a compost pile for a month or so to get beneficial microbes to occupy the ginormous surface area youve created, and watch your corn grow. i did a row with and without to prove it worked. they will be bigger and require less water. the first one will take you 30 minutes, 15 thereafter

bottom left is the contraption turned upside down. bottom right is another can acting as a wind shield with gaps cut so you can make a mini spit. poke metal rod thru the meat and lay it in those cuts

You can make small or big ones. It's basically burning wood in an oxygen starved environment, you're really burning the gases off of it. Take a 55 gal barrel, lay on its side and fill full of your chosen wood. Weld up 2 braces to get it a foot or so off the ground. At the top weld 2 pipes that go up about a foot or so, 2or 3 inch pipes. Elbow 90 to side the width of the barrel, then down, then underneath. Drill holes in pipe that is now underneath the barrel. Put some wood underneath the barrel and set ablaze. After about 10 minutes the steam from the wood inside the barrel will be driven off and the gases will ignite and you will have one hell of a roaring and dangerous situation if the pipe and holes are too small. The gases ignite and bake the wood inside creating even more gases creating a helluva cycle. Pyro dream situation. When it goes out wait a long time before opening it... The next day open and you have charcoal. Google pyrolosis and biochar. I make small camp stoves, can inside a can that are much smaller and safer to start with. I've made rocket stoves and such. Fire brick pizza ovens. I am now tackling the mastery of masonry heaters. I get ceramic fiber, firebrick, satanite, and refractory cement from harbison walker in Knoxville. I've always been interested in the efficient creation of heat. So sorry for the novel. Biochar will give your garden one helluva kick in the ass as well

Something similar to what I was describing, not safe having one outlet IMO in case it gummed up.

Finally, I would suggest subscribing to jw934 channel on YouTube. He's a jap who has some genius ideas for simple stoves, many of which I've built. I'd try the can inside a can, you just drill some holes in the right locations you could have one burning at your house in 15 min

Holy crap. I just spent two hours reading message boards on how to perfect a rocket stove. And I've never even heard of a Rocket Stove. Fascinating stuff.

Is this where you get "Sto Vol"?

I love stuff like this. I like the masonry heater and how great it looks but it looks a little complicated to build. I was looking to the rocket mass heater but I haven't found the burn times. I will need to leave the house and it takes a little time for these things to get up to temp.

The Masonry Stove


To the uninstructed stranger it promises nothing. It has a little bit of a door.. Which seems foolishly out of proportion to the rest of the edifice. Small sized fuel it used, and marvelously little of that. The process of firing is quick and simple. At half past seven on a cold morning the servant brings a small basketball of slender pine sticks and puts half of these in, lights them with a match, and closes the door. They burn out in ten or twelve minutes. He then puts in the rest and locks the door...The work is done.

All day long and until past midnight all parts of the room will be delightfully warm and comfortable...it's surface is not hot; you can put your hand on it anywhere and not get burnt.

Consider these things. One firing is enough for the day; the cost is next to nothing; the heat produced is the same all day, instead of too hot and too cold by turns..

America could adopt this stove, but does America do it? No, she sticks placidly to her own fearful and wonderful inventions in the stove line. The American wood stove, of whatever breed, is a terror. It requires more attention than a baby. It has to be fed every little while, it has to be watched all the time; and for all reward you are roasted half your time and frozen the other half... and when your wood bill comes in you think you have been supporting a volcano.

It is certainly strange that useful customs and devices do not spread from country to country with more facility and promptness than they do.

What is your opinion regarding the rocket mass stove?
Click to expand...

It's awesome. Peterburg on the forum I posted has come up with a firebox which is batch loaded like a masonry heater. All it is fundamentally is an insulated combustion chamber and heat riser... but you have to load it every few minutes cause it burns so fast... that's what you want tho... it burns so hot it burns the smoke too.. The key is saving that heat with thermal mass. The Europeans solved this centuries ago with the masonry heater. They're 10k dollars minimum tho. The rocket stove you can build with castable refractory and firebrick for a few hundred... Clay even cheaper. Peterburg has merged rocket stoves and masonry heaters. I think I could build a masonry heater for 2k if I did all the work... for a cabin or cheap home I'd go rocket stove with a batch box. I've built 6 or 7 rocket stoves but not the batch box yet. All these are great when the power goes out. Bake ovens and stainless heat exchangers are built inside for hot water as well

You might as well start a thread in the pub gents. You know that's where this conversation is landing :hi:

Nick I understand where you're coming from but he's signed already so... All threads are cluttered and meander....

it's one thing to sit around and bs with each other... we do that all the time.. it will get back on topic if something newsworthy happens. The previous may be off topic but at least it's disseminating something useful and I hope interesting to some

exhibit A cherry thread and using spikes as evidence speed is not needed at lb... forget the all world defense surrounding him

Sto I need to to find a way to get in touch with you. I would love to learn more and how to build them. I am mechanically inclined since I been in the metal fab business for 18 years.

Email freak and have him email me your email address, reference this post number (1615) in the Pearson thread

You have harbison walker or anh refractory close to you in Chatt. Lots of boiler furnaces down there and railroad type stuff. I think there is a brick plant too. Stop by and ask somebody where to buy refractory... It is so much easier to make your stuff that way. Make a wood mold, pour, vibrate.

All of this appeals to the engineer in me.

Lulz... True, but the small can biochar would produce enough to cook with . By small I'm talking a number 2 or paint can

Sto I have to be honest. I have no idea what you're talking about, but I'm reading everything you're posting and I feel like I'm becoming a better man from it haha

I made a rocket stove once that was made out of hardee backer.. The stuff used for tiles if you're familiar. Inside the j shaped contraption I put 2500 degree ceramic fiber blanket. Bought 55 lb bag of satanite and mixed it thin so it was like paint, maybe a little thicker. Coated the whole thing inside. Fired it up and you could still touch the outside of the stove after I had just melted aluminum with it... Lol. There's a really cool site called backyardmetalcasting that is really neat. These guys make charcoal burners, propane, used oil. They're are a very few who even melt iron. That is hot my friend. I haven't gotten into metals yet but maybe someday. I just tinker around sometimes, occasionally with dangerous shat. I'm not great at math or physics, chemistry, but I stay after it til I feel like I know just enough to be dangerous, then I let her rip. My education was in biology so go figure

Lulz. I should bring one to a game. If you like your steak Pittsburg style, pronto crispy outside, bloody as hell inside, a rocket stove is perfect. The temp is around 1000 f leaving the heat riser. Now that's searing

I was thinking something like that would cook the hell out of a Pittsburg style steak.

That's awesome. I could definitely see myself getting interested in something like this. I'll direct my wife to you when she complains about the internet research I'll be doing.

Also I'm all too familiar with hardibacker. I've been helping out my buddy who owns his own tiling business. Now that's a day of work.

I know I'm talking to a man's man when he gets his steak Black and blue (Pittsburgh).
