You can make this oven for the street yourself literally from improvised materials. You can use it in the country, in the village or in hiking conditions. Its advantage, in comparison with an ordinary fire, is that for kindling and cooking simple food or tea you will need not a large number of chips or twigs. Food is cooked quickly in such an oven, due to the concentration of heat and it is less likely to burn out, as the temperature is evenly distributed. In 15 minutes, the oven is able to bring 1.8 liters of water to a boil.
To make a homemade camping stove, cook:
- a large can
- an iron bowl
- metal hanger
- barbecue paint
- aluminum plates
- Dremel with a cutting disc.
Step 1. Mark the markings on the walls of the can. Closer to the bottom, mark 16 small holes - these will be the air intakes. In its upper part, labels for 8 holes will be needed. All of them should be located at the same distance from each other.
Step 2. Drill holes in the bottom of the can. Cut them out at the top of the jar, but you will only need to make holes 7. One of the marks should remain untouched so that hot air does not go through it and does not heat the handle of the dishes in which you will cook.
Step 3. Drill three holes in the form of a triangle in the bottom of the can. They will be needed for fastening the bolts.
Step 4. Drill the same holes in the bottom of the bowl.
Step 5. Attach the bowl upside down to the jar using bolts and nuts. Tighten them well.
Step 6. Opposite the untouched mark, make a hole in the jar for laying chips. Use a Dremel with a cutting blade for this. Process the edges of the cut so as not to get hurt in the future.
Step 7. Make a handle from a wire hanger. Drill holes for it and insert it into the oven from the can.
Step 8. From the lid of the can you need to make a kind of tile for the burner, it is needed to raise the flame above the air intakes. Drill holes in the cover so that air passes through it. Make three more holes for the bolts and fasten them to the cover with nuts. They will become the legs for the lid.
Step 9. Paint the oven specifically with barbecue paint. It is both heat resistant and safe.
Step 10. Make a grid for the stove. For its manufacture, you can take aluminum plates or another tin lid with neatly drilled holes.
The street oven is ready! You can use it for its intended purpose.
throw the gearbox out.
I tried, almost exploded.
Nurse. If the connections are tight, then the pressure in the small spray can and large Cylinder is the same. School physics course to help.
Yeah, I thought so too ...
good luck with your research!
How was the 5-cylinder issue resolved? Remove the gearbox with 5 l?
I didn’t even decide whether on hikes I took a 5 liter cylinder, but as a rule they cooked it at the stake, and on a long trip to the two seas, Black and Azovskoye, I generally took one small cylinder for the road, well, and there’s a place in the car was, and there, in every campsite where they lived they bought gas for tiles in small spray cans, and of course, lunch-dinners in cafes right on the shore to the sound of waves. And by the way, after Adygea, in general, there is tension with gas gas stations, there is no place to refill a cylinder.
Remove the gearbox from the big bottle and everything will work fine. The gas stove already has its own gearbox.
I connect a similar tile to a 5l cylinder without a reducer - everything is fine, nothing whistles. And with the gearbox - it was barely burning
Dear teammates, thank you all for the advice, help, tips.
Following your advice, I tried to connect a 5-liter cylinder to a straight line without a gearbox, the emergency bypass valve on the stove immediately worked, I was already scared, so the bitch whistled. So it is not in vain that the instructions say to connect large cylinders only through the gearbox.
At the next stage, I tried to disassemble the gearbox standing directly in the plate itself.
Indeed, as some colleagues suggested, there was shavings and some kind of dirt, I cleaned everything and it seemed to me that the spring on the membrane was taut, but I did not cut it yet, all of a sudden this is the membrane of the emergency valve.
I took the same tile from my friends, a new one, connected a 5-liter cylinder, it seems to burn better than mine, but it might seem, but the flame is also smaller than when working on small cylinders. Maybe there is such a design feature of all the tiles that from a 5-liter balloon the flower of fire is smaller than from a small spray can.
Conducted an almost scientific experiment.
Boiled a 2-liter saucepan without a cover of ice water on the street at +8 ° C.
On a friends tile, it took 18 minutes.
On my tile, it took 21 minutes.
I don’t know whether it’s long or not, I wonder how long it takes for you to boil the same 2-liter saucepan?
DIY beer can burner
To make the simplest spirit lamp, you will need two aluminum cans of beer or any sparkling water. So that the burner from beer cans does not smoke and does not melt when burning, it is necessary to clean its surface with sandpaper to get rid of the paint. Then you need to cut off part of each of the cans, about 3 cm from the bottom, with a clerical knife. The cut line must be flat, so you can use a marker mounted on a plank 3 cm high to draw this line, or fix the clerical knife in a vice, while twisting the jar, cutting off its necessary part. The sharp edges of the cut part need to be processed with sandpaper.
The resulting two identical parts of the cans must be connected by inserting one into the other. Since they have an equal diameter, the connection can be difficult because insert one into the other so that there is no gap between them. Since aluminum is easily amenable to deformation, before you cut the second billet, you can pull the cut, finished part of the future spirit lamp onto the bottom of a whole can, thus expanding its edges to the desired diameter.
After both parts are connected, around the perimeter of the upper part of the spirit lamp you need to make holes with an awl or a drill of 1-2 mm. They can get 18-20 pieces with the same distance between them. In order for the flames to rise, the edges of the holes need to be slightly bent up. At the top of the burner, you need to make several holes of 3 mm diameter for pouring alcohol and adjusting the internal pressure of the container.
A do-it-yourself beer can burner works very simply: 30 ml of alcohol is poured inside, the inlets in the center of the top are closed with a coin. The bottom of the spirit lamp warms up with a match, the alcohol vapor lights up, forming flames that exit the holes made around the perimeter.
Beer can burner
To make it convenient to heat water or food on the burner, you need to make a stand for dishes. To do this, use a slightly larger jar, for example, from canned food. On it you need to mark two lines: one at the height of the burner, the second at height, twice the length of the burner. The top of the can is cut off, and its walls are divided into 12 vertical incisions. Of this number, you need to leave six pieces, cutting off the excess through one. In the center of the bottom, you need to make a hole for heating, and bend the remaining strips inward to the bottom. The stand is ready, it remains only to place an alcohol burner inside it.
Tin can burner
Tin can burner
In addition to using beer aluminum cans, an alcohol lamp can be made from a regular can. A burner made from a tin can of coffee or brewed tea with a tight-fitting lid is also excellent.
The principle of manufacturing a burner from a can is similar to that described above:
- Several holes are made in the lid for pouring alcohol.
- Next, you need to make holes along the diameter of the upper edge of the can at a distance of 1-1.5 cm. They should have a diameter of about 1 mm and the edges bent up at an angle. This is necessary so that the alcohol vapor goes up.
- The cans are ignited in the same way as beer cans, with pre-closed openings at the top using a coin.
In principle, an open alcohol burner can be made; for this, a lid is not needed. To do this, insert a tin plate rolled into it in a circle with a diameter smaller than the walls of the can. Inside the resulting circle in the center, alcohol is poured and set on fire.
As with any combustible substance, handling alcohol requires caution. You can’t fill the can to the top with it, otherwise it may explode. In addition to alcohol, it is not recommended to use other types of fuel. The burner can not be installed at home on the table, because it can catch fire, and in general, when using the spirit lamp in everyday life, it is necessary to use a stand for both the burner itself and the dishes. To extinguish the spirit lamp, it is necessary to stop the access of oxygen to the burning vapors of alcohol, for this you can cover it with a tin lid on top. It is not allowed to use a torch to heat small synthetic tents.
