Ammo Can Rocket Stove
Bear Ridge Trading POst ^ | 7/31/11

Posted on 02/24/2012 12:56:05 PM PST by Kartographer

A rocket stove is an efficient cooking device that uses small twigs and branches as fuel to achieve high temperature cooking though an insulated combustion chamber and feed tube.

Here are the plans for a quick and easy rocket stove that’s made out of an old ammo can, a piece of stove pipe and a used coffee can. I built this ammo can rocket stove in under an hour and it works great.

This is cool! Made me go 'WHY DIDN'T I THINK OF THAT!'

I will eventually replace the DIY Rocket Stove section in my Preparedness Manual with this one as ammo cans are a lot easier to get and the shape makes it easier to store and pack. I almost think that a 20MM ammo can would be big enough for a two burner Rocket stove!

I know that I have already posted the weekly Prepper Ping, but this was such a GOOD idea that I just had to give it it’s own thread.

Do I smell something cooking?

Oh, yeah, it’s a lawsuit (BOOM!).

The whole point of a “rocket stove” is that the chimney is highly insulated and provides a very high draft...

I don’t see a chimney here, much less an insulated high temperature chimney to provide the high draft necessary for the efficient burning of a “rocket stove”.

I didn't see the need to post every picture from the site. I assumed that people would go there and review the writters instructions.

The Heineken mini keg also makes a great rocket stove, you also get a mini keg of beer.
Other labels also use the mini keg, but I’m not sure which.

The integrated handle on the ammo box is a clear advantage here.

I used to futz around with these as a kid, and picked up a few useful pointers.

1) There is still a lot of native coal in the US, and a lot of states have outcroppings of it where you can just help yourself. Almost nobody looks for it or imagines that it is useful, but if you know where some is, it can save a lot of wood chopping.

2) A cheap set of bellows can get your fire hot and ready much quicker, especially with sub-optimal fuel. They are commonly sold as home fireplace decorations, but never used by most people, yet they work.

3) Always keep a squirt gun handy to cool a fire that is too hot.

4) Fires produce three kinds of useful heat. Convection heat from hot air, which is fast; Conduction heat in things that conduct heat, like metal and liquids, which is somewhat slower; and Infrared heat given off by conductors, which can last for hours. If fuel is scarce, it is important to remember and try to use all three.

Most Americans aren’t too familiar with using Infrared heat to heat an area, but the concept is an old one, and widely used where fuel is scarce. On the large scale, it is used in “oven stoves” or “tile stoves”. (great web page, btw, with lots nice pretty pictures):

http://www.lowtechmagazine.com/2008/12/tile-stoves.html

Most people don’t want to lug around stone blocks to absorb the heat of their fire and give it off as Infrared, however, but there is an easy solution: It works just as well if you use sand or powder from these high energy density stones.

In order of energy density, from high to low, is gypsum, soapstone, basalt, marble, limestone, sandstone and granite.

So bottom line, instead of using just sand as insulation for your oven, use common, inexpensive gypsum powder, that can be found in any garden store. It will absorb lots of heat, acting like a good insulator, and then give off Infrared to heat the area around it for a long time.

A small amount of fuel can do a lot if you don’t waste it.

“Masonry Heaters” - use the concept of the rocket stove - high temperature, high draft, high efficiency

to heat a huge mass of masonry brick up fairly quickly, and letting it radiate the heat for several hours after the fire dies.

I made some alcohol stoves from soda (beer) cans that work great. There are a lot of great designs on the Internet.

The problem with alcohol stoves are they don’t always get hot enough to boil water. For food and water you want it hot enough to santize both.

I can boil 2 cups of water in 4 1/2 minutes on about one half ounce of alcohol. A wind screen is a must, though.

My understanding it depends on the altitude and the outside temp the water boils but is not 212 degrees.

Excellent idea. Thanks for posting!

I took the lazy way out and bought a rocket stove long ago. However, I only have one and more will be needed if TSHTF.

These things would also be great for barter if/when the time comes.

Rocket stoves can get VERY hot, especially if someone uses coal or charcoal. Stove pipe is designed to stand up to high temperature, but I’m wondering about the coffee can. Have you used yours enough to know how well it holds up?

This picture seems to show the extra space filled with sand; the directions referenced say not to use sand because it absorbs too much heat. Why did you use sand?

FWIW, it’s tougher to lay your hands on ammo cans. They are now considered traceable items and not freely procured anymore. Additionally, I saw somewhere, ..I believe some homeland security regs label ammo cans as being associated with items of interest for ‘terrorists’. Some perceive them as providing justification for arrest or at least a ticket and confiscation if observed during a traffic stop. Just be sure to relabel/repaint yours so it isn’t as quickly so identified by the illiterate legalist.

I also used a small piece of a broke decorative concrete edge as a support under the pipe to hold it in place better. You can pick in a small concrete cobble stone at any lawn and garden center to do the same thing.

“20MM” is the form of answer I was looking for.

There’s a vendor at the local periodic gun show that sells virtually nothing but ammo cans, in all sizes.

There’s one coming up in mid-September.

Thanks for the info.

From the pictures here and at the Bear Ridge site, it appears that the “tunnel” is used for fuel and air supply, and that the combustion takes place primarily in the “silo”.

Is that correct?

Primarily the fuel itself burns at the end of the fuel chamber you actually want to keep the fuel out of the bend area. There is secondary combustion taking place cause by the intense concentrated in the exhaust tube one of the reasons the burn is so complete with little to no smoke.
