I like hiking. I also like to cook. But I have a negative attitude towards burning non-renewable energy sources.
So what alternatives can you suggest? Obviously, you can just light a fire, but this is not allowed in all places. Simply heating a pan of food takes a lot of wood.
So I set myself the goal of making something portable and wood-burning.
I came across the idea of a rocket stove earlier this month, so the choice of device had already been made.
Finding a helium cylinder and cutting it.
The main part of a portable rocket stove consists of an old helium tank.
I found two from a friend of mine who recently had a wedding.
Empty the container. Helium does not burn, but opening a vessel under a pressure of 295 atmospheres is not the best idea.
Cut off the top and make a hole on the side. The size of the hole depends on the size of the fuel hopper.
Preparing the profile pipe
The fuel supply must be arranged in such a way that the flame freely reaches the top of the housing. You need to add a cutout in the profile pipe to make it more convenient to connect to the body.
Even when supplying firewood through the fuel hopper, we need to ensure free passage of air into the stove. For this purpose I used a metal grill taken from an old radio.
Support for structure
For the stability of the structure, it was necessary to make two legs for the fuel bunker.
I stapled everything together. Legs and grille to control air flow through the walls of the fuel hopper using locknuts.
The nylon nut ring will not be subject to excessive heat since it is located far enough from the firebox.
Spike for stability
To increase the stability of the stove, add a spike at the bottom of the cylinder. To do this, I welded a nut to the cylinder.
I made a through hole in the bottom part so that for ease of transportation, the tenon could be secured inside.
Heating surface
In order to place a pan on the stove, you need to make a heating surface for it. I made it from an old baking sheet.
This material is easier to work with and is strong enough to withstand even heavy kitchen utensils.
We carry out the first assembly of a camp stove
This is what the assembled oven looks like. I treated its surface with a special paint that can be heated to a temperature of 800°C.
We disassemble the oven
For transportation, all parts can be detached from the housing. All parts are sized so that they can be placed inside the oven, and so that they do not rattle during transportation (except for the heating surface)...
Let's use all the space
I found the sounds made by the disassembled heating surface during transportation to be irritating, so I filled the free space of the stove with firewood. So I came to the conclusion that it would be useful to have some dry wood for kindling.
Enjoying cooking outdoors
I tried frying bacon and eggs. You can even cook a whole pot of beans.
Thanks to the oven, you only need a couple of logs to fully cook a dish. And the wood will burn out completely, creating almost no smoke.
We increase the stability of the structure (hull)
It's time to improve the result of the work.
The oven turned out to be generally successful, but a little unstable. To improve this characteristic, I used a cable from a bicycle brake system, adding a hole in the housing.
We increase the stability of the structure (fuel bunker)
I then made a small cut in the top of the fuel hopper and flattened the cap on the end of the cable.
We increase the stability of the furnace structure
Now you can attach the base to the fuel hopper.
The oven has thus become significantly more stable and has not undergone major changes in terms of transportation.
Watch a video of testing a camp stove
As a test, I made a wonderful baked bean dish. Two hours faster than at a campfire, and the smell is just wonderful ;-)
