There are quite a few 'Ammo Can' Tent Stove videos on YouTube - built along the traditional box stove format - but very few folk have taken up the 'rocket' option.

However, if you Google "Ammo Can Rocket Stove Kartographer", you'll see a very simple open-air cooking stove made from an Ammo Box, a s/s elbow. and a few handfuls of perlite. Now - if the saucepan support bars were made easily removable, and replaced by a bolt-on chimney, insulated where it passes through the canvas, of course, then you could have a really neat and simple 'Ammo Box Rocket Tent Heater'.

Thinks - if a rocket riser was made from a s/s tube inside a fire extinguisher (say), then the flue could be taken out of the tent horizontally. That would really get the neighbours talking !
Over to you ....

I like the first stove but it seemed a bit inefficient for heat output. I don't know if that's the nature of rocket ovens but I would think something as simple as adding 2 - 4 ft of exhaust pipe would help a lot. Lowering the location of the exhaust outlet would be helpful as well. Maybe this was built specifically to get the oven readings it was getting, which I suppose were reasonable.

from cold they are inefficent its once you get them warm is another matter

also the height is important thats a small scale version but does the job in ample time more height means more weight to transport added advantage gives heat off

rocket ovens are not a new consept take a look at aga and rayburn and esse cookers there the oldest cooker based systems

I have made a few tent stoves, one out of stainless steel food trays, one from a gas cylinder and one from an ammo box. None of them are rocket stoves but I thought that a little discussion about how the jack (the interface between flu and tent wall) and how they perform might be worthy.


The SS tub version measures 12 x 6" with an internal baffle, and although it functions very well as a tent stove, the door is way too small, meaning that fuel has to be processed to suit and I'm constantly monitoring and refuelling it.


The 50cal ammo can stove solves this problem and once I added some secondary air intakes and lined the interior, is very adjustable and works very nicely(for a box stove)

This is the flue set up outside of the tent for both stoves. The flue is wired to a bipod.


The gas cylinder stove has a horizontal flue exit and a ninety degree elbow. I usually wire the flue to a stick bipod so it can't touch the tent wall. I have since invested in a 7' roll up stainless flue from seek outside, a great piece of gear for tent camping(also comes in titanium)




This is by far the most efficient stove. Once up to temp, it burns smokeless and puts out an impressive amount of heat. The large door means that big hardwood logs can be used and, with sensible air control, doesn't need to be watched constantly. Also a good cooking surface for cast iron ovens etc.
However, I'm sure that a rocket stove would out perform all of these easily.

I haven't added a flue damper, as I want to be ultra careful about carbon monoxide build up inside the tent. Not sure if I'm being over cautious, but it's something that I will always trade over efficiency in this application.

The stove jack is made from a fibreglass fire blanket with a ring of carbon felt stitched around the hole with fine cable. It has lasted for 2 seasons so far and doesn't show any signs of degrading. This tent and stove project was all made from recycled materials(the tent from an old canvas tarp and the stoves from various stuff in my shed) and was really to see if I could make a winter hot tent set up without spending very much money(about $40).

I'm not sure if you would need further heat insulation in your stove jack, with a rocket stove or not. My guess is maybe not on a canvas tent, but everything needs to be more protected in a synthetic tent.

nice interesting setup i have seen the bigger version of the ss plate on youtube had even got a copy of it on other hard drive for reference

the rocket stove is good however poor when it comes to refilling them then the use of wood pellets come into there own but these have there problems as well and can block up the fire chamber and co2 is within the tent

I find this little stove to be a useful heater. It might be good inside a tent for some quick heat.  Burn time can be adjusted by how many holes are punched in the bottom of the paint can (and depending on the exhaust flue length).  The heater cranks out tons of radiant heat.  Of course, co may be an issue at the end of the burn since the stove is not sealed.

I was going to suggest that a pellet feed would be good in this application, as it will self feed, but I don't have any experience with them. It's interesting to hear that they can clog, it would be pretty bad in a tent setting.

yeah theres a few that can do it

look at wiseway burner real life not the advertised





theres a few designs on here that do use pellet burners to burn some succesfull but theres always a chance that it may block up with unburnt pellets depending on your design
