DIY camping pyrolysis oven

Design features of a camp stove and its advantages

A self-made camping stove is a wonderful and useful device for relaxing outside the city and in the forest.
It is indispensable for fishing and camping with a tent. If the design provides for the presence of grates, such a furnace is characterized by good draft. Consequently, the fuel will burn very quickly. Therefore, it is best to use firewood for a camp stove.

In devices without a bottom, the fuel is placed directly on the ground. Firewood or other fuel burns more slowly, and coals do not smolder for a long time. The process is resumed with a new batch of fuel loaded. This type of tourist stove provides less heat due to the lack of draft.

The camp stove, equipped with stands, is characterized by maximum traction, which speeds up the process of frying food. If you need to cook food by boiling, the stands are removed and the oven is placed on the ground. In this case, the grates overlap, oxygen enters in less quantity and the combustion process slows down. In this case, the cooking time increases.

Regardless of the design, camping stoves have many advantages:

• Wood stoves are quite economical.
• The fuel burns in any weather.
• The devices can even be used inside tents.
• The manufacture and operation of the stove is quite simple.
• Possibility of manufacturing a mini version of the stove.
• Easy transportation.
• Adjustable fire power.
• Complete security.
• High performance.

As we found out, a camp stove is an extremely useful device, which is difficult to do without when fishing or just relaxing outside the city. If we talk about standard stoves with grates, they require large volumes of firewood due to good draft. In short, the fuel burns out quickly.

But in structures without a bottom, where firewood lies directly on the ground, combustion slows down, the coals smolder for a long time, and after loading a new portion, flare-up occurs instantly. But the draft in this case is poor, and heat is practically not accumulated.

In hiking designs with stands, traction is maximum. If the dish you plan to cook should be cooked over low heat, then the stove should simply be placed on the ground, thereby blocking the grate. In this case, the supply of oxygen deteriorates, combustion slows down, and the time, accordingly, is extended. But regardless of the design, all stoves of this type have significant advantages, including:

1. efficiency;
2. versatility and independence from weather conditions;
3. efficiency;
4. compactness;
5. long burning without smoke formation;
6. ease of use and transportation;
7. power adjustment;
8. safety;
9. performance.

We also add that due to the fact that the wood burns from the inside, the stove body does not heat up much. You can even hold it in your hands for a while, since wood effectively insulates heat. But, of course, you always need to be careful when working with open fire!

Option #1. Miniature stove made from a tin can

Wood-burning camp stoves made from a tin can are the simplest mini-version of a single-wall design. To make them, you can take a tin can or an unnecessary iron mug. Accordingly, the height of such a product will be approximately equal to the height of the glass.

For the manufacture of a mini camping stove and its further operation, the following scheme is used:

• The bottom of the jar or mug is pierced with a sharp object in several places. Air will enter the combustion chamber through these holes, and the fire will be stronger. The holes should not be made too large to prevent coals from falling out.
• Small wooden blocks are placed inside the jar. They should be positioned strictly vertically and not look beyond the top edge of the jar.
• Now they pull out one log from the middle to provide air access to the firewood.
• The free space between the logs is filled with paper and grass and set on fire.
• Burning in a mini camp stove lasts about half an hour, which is enough to whip up dishes.

It should be noted that in this case there is not a large amount of smoke around.

When cooking outdoors for a large number of people, you should take a jar with a volume of one or two liters, in this case the fuel consumption also increases. Therefore, to maintain the fire, it is better to take thicker wood, which will provide heat for about an hour.

The most primitive single-wall option is a DIY camp stove made from a tin can. In the process of creating it, you will need an ordinary tin can or an iron mug, but always of a minimum size (about the size of a tall glass). In the future, you will have to perform such actions.

Step 1. First, make a couple of holes in the bottom of the mug or jar to create draft (they will serve as sources for supplying air to the body). It is important that these holes coincide with the internal air flow channel. There is another option - to make one large hole in the bottom, but in this case the coals may fall out.

Step 2. Then fill the jar with small (about the thickness of a finger) wooden blocks so that they do not extend beyond the edges of the jar. The stacking of firewood should be strictly vertical (something like an “Indian candle”).

Step 3. After this, remove the block from the body, which is located in the center - this will provide a channel for the passage of air.

Step 4. Place paper or dry grass into the formed channel and set it on fire.

Step 5. This design, the volume of which will be approximately 500 ml, will burn for about 25 minutes, which is more than enough to whip up something. The area will not be filled with smoke!

Step 6. Of course, if many people take part in the hike, then the jar should be larger - at least by one or two liters. But in this case, to obtain stable combustion, thicker firewood must be used, and in larger quantities.

The flame “produced” using this design will burn for about 60 minutes. This is enough to properly boil potatoes and fry shish kebab on smoldering coals. This is just one of the manufacturing options. Now let's move on to the next one.

What is a camp stove for?

A device such as a camp stove can easily replace a fire. At the same time, it requires less fuel than when lighting an open fire.

In addition, the following can be used as fuel:

• Cones.
• Tree bark.
• Woodchips.
• Dry branches and reeds.
• Cooled used coals.

It should be noted that when burning the same amount of fuel, a stove produces much more heat than a fire. Therefore, the oven can cook more food in a shorter period of time.

All furnace devices are divided into two types: single-walled and double-walled. In addition, the stove can be folding or made in a mini version. A camp stove can be made at home or directly at your vacation spot. In both cases, the process makes it easier to use the drawings.

To make a camping stove, various available materials are used, including unnecessary pots, cans from preservatives, or ordinary metal sheets.

When choosing a material, it should be taken into account that the stove must meet the following requirements:

• Low heat consumption.
• Low weight and dimensions.
• The ability to heat dishes, not air.

Option number 4. Construction of several tin cans

First you need to prepare three canning jars (two smaller and one larger). After that, take these tools:

1. metal scissors;
2. asbestos;
3. marker.

Follow these steps:

Step 1. Make blanks. Take a large jar, step back about 20 centimeters from the bottom, place a smaller jar there and circle it with a marker. An even circle should form.

Step 2. Cut a hole in this circle, make sure that the jar fits into it, but with difficulty.

Step 3. Make a similar hole in a smaller jar. Place the smaller one in the larger one.

Step 4. Make parallel cuts of approximately 2-3 centimeters on one side of the jar.

Step 5. Take the lid from a large jar and make a hole in it for a small one. Sand the cuts.

Step 6. On the wall of the jar, make vertical slits of approximately 1.5-2 centimeters.

Step 7. Fill the voids between the cans with asbestos, then close the lid and bend the metal.

Step 8. Take a piece of tin and make a shelf for firewood from it, secure it.

Step 9. Now just attach a handle to make it convenient to carry the structure. That’s it, your DIY camp stove is ready! You can paint it.

As a conclusion

When planning an outdoor recreation, all household items must be provided in advance. Of course, a camp stove can be purchased at any specialized store, but it is much more pleasant to make it yourself. After all, this will give you the opportunity to save money and realize your fantasies, and have a great time in the fresh air. Good luck with your work!

Any home craftsman can make a simple mini-oven powered by wood in just a couple of hours. To assemble it, you will need three cans of different capacities:

• The first is taken to be the largest. It will serve as the shell of the structure being manufactured.
• The dimensions of the second should be such that it fits in the first without any problems.
• The third has the most modest dimensions. It plays the role of a burner for a homemade camping unit.

Additionally, you should stock up on a small block of wood, scissors for cutting metal, a drill and a regular marker. You can make a wood-burning camping stove from cans very simply with your own hands using the algorithm given in the next section.

Using unnecessary pots to make a stove

To make a double-walled stove, you will need an old unnecessary pan; a stainless metal product would be an excellent option. This version of the stove can be used on a hike due to its light weight, ease of manufacture and affordable fuel for it.

The design of a double-walled camping wood-burning stove consists of one container inserted into another. A hole is cut out in the lower element where firewood will be placed. The bottom is cut with a sharp knife in several places to form a kind of grate. A small stand is placed at the bottom and firewood is placed on it.

The second container needs to be taken a little smaller so that it fits inside the first pan. The fire in the lower element will heat the upper pan. They also make a bow, with the help of which the resulting pot can be removed from the heat without getting burned. Cooking food while camping in the fresh air with the help of such a stove is very simple and pleasant.

Both versions of the camping stove are lightweight, do not take up much space and are easy to transport. You can also use the devices in a tent in adverse weather or move them while the fuel is burning. But such stoves cannot boast of a long operating period.

Do-it-yourself folding camping stove

There are several more options for assembling structures for cooking in camp conditions. Rocket stoves are characterized by a high level of efficiency. They are monolithic (non-removable) structures built from:

• heat-resistant concrete;
• steel pipes;
• red brick with high fire resistance.

It is unrealistic to transport such structures in a car. Therefore, they are usually erected in dachas.

Pyrolysis stoves, having a high efficiency rate, are very difficult to build with your own hands. Only experienced tourists with engineering skills can do this task. Such installations are made from special grades of steel, which are characterized by high heat resistance.

An Indian candle is an exotic version of a camp stove. It is believed that he came to us from America. This rare design is made like this:

• They find a large log (log) that is necessarily hollow inside. Splits into 4 parts.
• The resulting workpiece is thoroughly cleaned from the inside.
• Separate pieces of logs are connected to each other (with nails or in another way).

Small twigs, dried grass, and birch bark are placed inside the assembled wooden structure and set on fire. The flame can be adjusted. The deeper you push the fuel used into the Indian candle, the stronger the fire will be.

It is optimal to use an aspen log to make the described exotic stove. It is undesirable to use birch and coniferous blanks. The former give off too strong a flame, the latter, when burning, emit a lot of sparks and shoot.

A folding stove for a camping trip can be called a fairly effective option, but you will have to spend a lot of time and effort to make it. This option requires the presence of a pre-compiled drawing and a set of necessary tools and materials. In particular, you should prepare the following:

• Electric drill.
• Pliers.
• Roulette.
• Bulgarian.
• File.
• Metal sheet 1 mm thick.
• Piano hinges.
• Bicycle spokes or thin wire.

To make your own folding version of a wood-burning camp stove, you can use the following instructions:

• In accordance with the drawing, structural parts are cut out of a metal sheet using a grinder.
• A hole is cut out in the part that will serve as the bottom of the product. The burrs around it are cleaned with a file.
• The side parts of the stove are connected using piano hinges. The result is a kind of box.
• One-sided bends must be made along the perimeter of the bottom, as well as in the lower and side walls.
• The bottom and the box are combined, and the folds made should create a tube. Bicycle spokes or thin wire are inserted into it.
• Protrusions with slots on the sides are made on the grate.
• On one side of the stove, use a grinder to cut out a hole for storing fuel.
• Slots are made along the top edge into which skewers can be inserted for frying meat.

A DIY camp stove made of metal is ready for use.

A very effective design, the manufacture of which, however, requires more time and effort, as well as preliminary preparation. First you need to acquire the following consumables and equipment:

1. roulette;
2. Bulgarian;
3. electric drill, as well as a set of drills for it;
4. file;
5. pliers;
6. bicycle spokes;
7. piano hinges;
8. sheet of metal 1 millimeter thick.

We also note that in order to make a folding stove, you can use:

1. iron sheets from the body of an old gas stove or refrigerator;
2. side walls from an old computer system unit (these options can replace sheet steel).

Note! When starting to create a folding camp stove, be sure to familiarize yourself with its sketch, and also create templates for the planned structural elements based on it.

During the work, you will need to perform the following algorithm of actions.

Step 1. First, mark all structural elements on sheet metal using prepared templates, then cut out these elements using a grinder.

Step 2. Make holes in the piece that will be used to arrange the bottom.

Step 3: Next, file the edges of the holes to remove any burrs.

Step 4. Connect the side walls of the structure together using piano hinges with rivets. As a result, you should get a kind of box.

Step 5. Along the entire perimeter of the bottom, as well as on the lower edges of the side walls, special “ears” bent in one direction must be provided in advance.

Step 6. An element is placed under the formed box, which will serve as the bottom, while the “ears” of the two elements will align on each side and form a tube. Pins made from knitting needles must be inserted into this tube. This little trick allows you to make the stove more stable in its operating state. In addition, if necessary, the structure can be easily disassembled for transportation or storage.

Step 7. On the grate, make additional protrusions installed in the holes that are cut on the sides.

Step 8. There will also be another hole in the sidewall through which fuel will be loaded.

Step 9. The cutouts made in the top of the box not only increase traction, but they can also be used to place skewers.

The process of making a heat exchanger for a tent

Front and back covers:

From a sheet of galvanized steel we cut out two squares measuring 250 × 250 mm. In the sheets we drill 4 rows of holes with a diameter of 10 mm in a checkerboard pattern. For a mirror arrangement of holes, they are made in two sheets at once. Using a sheet bending machine, we bend the edges of the sheets at 25 mm to get low boxes.

Using a thick core or a round piece sharpened to a cone and a pipe with a diameter of 25 mm, we expand the holes.

We hammer the core inside the box.

Pipes:
We cut aluminum pipes (18 pcs.) 350 mm each.

We make a pipe with a diameter of 50-60 mm from metal or purchase a ready-made one. It is advisable that a polypropylene pipe be put on it, which will serve as a chimney. Using metal scissors, we make a dozen cuts 20 mm long and bend them outward using pliers, as shown in the figure.

Side walls and top:
We cut out a solid sheet from the metal, from which we bend the side and top walls of the heat exchanger.

In the upper part we drill a hole corresponding to the diameter of the metal pipe for the chimney.

We drill small holes around the perimeter with a reserve, and then use a chisel to cut out a large one.

Using a file or drill, we adjust the size and geometry of the hole so that the pipe fits tightly into it. We remove hangnails.

Using a sheet bender, we bend the heat exchanger body.

You can roll the sides to add rigidity to the structure. We drill holes in the pipe petals and the body and use rivets to connect them.

Assembly:
To simplify assembly, insert the bottom row of pipes and tighten the front and back walls using a pin or clamp.

We fasten all the elements of the assembled structure using resistance welding (you can use rivets).

To increase the reliability of fastening using a core, we further expand the holes on both sides of the heat exchanger.

Description of pyrolysis and gas furnaces

Pyrolysis and gas stoves are very convenient for use on hikes and vacations outside the city. They are characterized by an excellent combustion process, so they are quite suitable for quick cooking in the fresh air. But you cannot make such stoves yourself; they are purchased in specialized stores.

The pyrolysis stove is highly efficient, so the models presented from the retail chain have a fairly high price. Compared to wood stoves, this option is characterized by greater productivity. Those who decide to make such a device with their own hands must have special knowledge and materials. In addition, it should be borne in mind that a homemade stove in nature does not give the desired effect.

Among the advantages of a pyrolysis oven are safety and environmental friendliness. In such a device you can burn excess garbage and cook food; the fire in them burns constantly without failure. The pyrolysis furnace is made from steel that is resistant to high heat.

A camping gas stove is also suitable for traveling out of town or camping with a tent. In the retail chain, such devices are presented in a wide range; you can choose a stove of any color and cost. The gas oven runs on a special cartridge that requires regular replacement. However, you can cook food on such a device without difficulty.

Before going on vacation outside the city or camping with a tent, you should take care of all the necessary things, including a camp stove. For regular use, it is better to purchase a good stove for tourism in a specialized store. And for occasional and very rare trips to relax in the fresh air, you can use self-made devices that do not require spending money, effort and time.

Factory models

Let's look at the most popular types of heat exchangers for winter tents. The equipment is new, so we won’t see much variety here. But what is on sale is more than enough.

Heat exchanger Sukhovey

We have before us a good device, made of durable stainless steel and aluminum pipe. It features a capacity of up to 184 cc. m/hour and can operate at high and low speeds. The carefully thought-out design ensures high efficiency, and the low-noise fan relieves users of unnecessary noise. The device easily unfolds into working condition and works with tiles from the manufacturer Hephaestus. The cost of the model is approximately 7,000 rubles.

It is also possible to use other burners that are compatible in size with this heat exchanger.

Heat exchanger for fishing Sibtermo ST-1.6

The presented model is distinguished by the presence of two fans at once, which increases the throughput. This is an excellent heat exchanger for a tent for winter fishing, allowing you to warm up a large volume of air as quickly as possible. The weight of the unit is only 1.88 kg, it can be used in conjunction with any gas and infrared burners. Even in the most severe winter, your tent will be warm and comfortable. The chimney in this model is connected from above.

The cost of the heat exchanger for the Sibtermo ST-1.6 winter tent is about 5,600 rubles.

Heat exchanger "Desna BM"

Extremely compact, with one fan, ideal for a winter tent. Works in both automatic and turbo mode. Can be used in conjunction with any burners and stoves (including infrared). The case is made of stainless steel and protected by durable enamel that can withstand heating to high temperatures. The manufacturer claims high efficiency, incomparable to the efficiency of any other analogues. The cost of the unit is about 7,000 rubles.

Gas stove for tent

A camp stove with one or two burners, powered by gas, is often used as a heater. Depending on the model, weight can vary from 400 g to 2 kg. This option has the following advantages:

• the ability to conveniently cook or reheat food;
• the surface is easily washed from dirt;
• often the design allows for folding into a compact suitcase;
• economical fuel consumption;
• presence of a protection system.

As in special heaters, a gas cartridge is used here. It is not included in the package, but must be purchased separately. It is better to give preference to models with a safety valve that shuts off the gas supply in case of overheating or other unusual situations. Resumption of combustion occurs after pressing the red button located on the gearbox.

It is important to remember that heating a tent in winter while fishing without burning out requires constant ventilation of the space. At least a minimum gap should be left so that combustion products escape into the atmosphere, excluding accidental poisoning.

Gas heater for tent

The travel heater option is perhaps the safest. First of all, it was originally designed to create heat in a closed room, so there is no risk of ignition of other objects, carbon monoxide poisoning, etc.

Such heating devices weigh no more than 1.5 kg and are very economical. So, on average, about 200 g of gas is burned in 4 hours of operation. At the same time, the device will not allow you to freeze even in severe frost.

Most models are equipped with piezo ignition, which eliminates the need to use matches or a lighter - the tool for creating a spark will always be at hand. Some users note that in severe frost the heater loses power and the gas entering the tent heater stops evaporating. In this case, you need to warm up the fuel supply pipe with several matches or a tablet of dry alcohol.

It is recommended to choose a model with a gas preheating system. Its essence lies in the presence of a tube that passes through the flame and frames the cylinder. As a result, the gas is heated before it exits, and therefore burns stably even at a temperature of -30.

It is important to leave a ventilation connection with the outside space. This will allow:

1. Avoid the formation of condensation inside the tent, which will prevent things from getting damp.
2. Ensure timely removal of carbon dioxide, which has a detrimental effect on the general condition of the body.

Among the advantages of a gas heater are:

• space heating rate;
• good drying of clothes;
• ability to heat food and water.

The disadvantages include:

• the relatively high cost of the device and the fuel cartridges themselves;
• the need to replace the canister at night.

Burners (primus stoves)

This is a universal heater option that, depending on the model, uses gaseous or liquid fuel. Mostly specialized stores sell gas burners. When choosing a model, you should pay attention to the power - not lower than 2000 W. With this value of this parameter, a liter of water will boil after 5 minutes.

Options that can support the combustion process from both types of fuel deserve special mention. The transition between gaseous and liquid fuel occurs by replacing the nozzle.

A pure gasoline tent heater has such advantages as frost resistance, convenience, reliability, and good heat dissipation. However, despite all the positive aspects, it cannot be recommended to fishermen and here’s why:

1. A canister of liquid fuel weighs much more than a gas cylinder, and if you need to cover a long distance on ice in search of fish sites, this can be a significant challenge.
2. Even with the most careful use, fuel will get on your hands. In all other cases there is nothing wrong with this, but during fishing it will negatively affect the catch. After contact with tackle or bait, the smell of fuel will remain on your hands, which can be easily heard by underwater inhabitants.

1. When gasoline and kerosene burn, a lot of carbon monoxide and soot are released into the air. The tent will have to be kept open, and all clothes will stink of combustion products.

There are also kerosene heater lamps. They have all the pros and cons indicated for liquid fuel heaters.
