Making a wood chip stove with your own hands at home

A wood chipper is a heating device that runs on wood chips, branches and other similar materials.

Those models that are available in regular and online stores do not always correspond to a given situation.

That is why they are often made independently.

In this article we will show you how:

• choose shape and size;
• choose metal;
• draw up a drawing;
• make oven parts yourself.

Making a wood chip stove with your own hands

Homemade stove
The stove is easy to make with your own hands; it will be difficult to find a similar product in stores. The furnace has a common structure and can be made of various materials. For self-production you will need the following tools:

• angle grinder (grinder);
• Hacksaw for metal;
• Metal scissors;
• Hammer;
• Electric drill;
• Pliers;
• Measuring tool;
• Punch.

At the first stage, a drawing of individual elements of the device is made. According to the diagram, individual structural elements are cut out using a grinder. Typically, a steel sheet with a thickness of at least 1.5 millimeters is used to install a collapsible furnace.

The side elements (4 pieces) have slots and protrusions for mutual fastening of the walls and the grate. To install the grate, you can bend the lower edge of the side walls or cut out the tabs and bend them inward. The upper grille is made of steel wire or small diameter reinforcement. The grille can be removable. The side walls can be secured using bolted connections.

An opening for the door is cut out in one of the side walls using a grinder. Secure the door on the hinges. Sometimes the door is hung on metal wire hooks passed through the holes. Holes are drilled along the perimeter in the side surfaces for air intake. Devices for driving pegs or steel legs (knitting needles, bolts, etc.) are mounted in the lower part of the oven.

For ease of assembly and disassembly, the side panels are often fastened together using door hinges.

Oven from a washing machine drum

Another manufacturing option is to install a stove from a washing machine drum. The drums of the machines are made of stainless steel, which has high strength and durability. To do this, a strip 60 cm long and 200 mm high is cut out. The strip is bent in the form of a cylinder, the joint is secured by folding the edges, riveting or bolting.

The strip is cut with three to four protrusions, which will be located along the perimeter of the circumference of the lower part. The protrusions are bent inward with a hammer, and a grate ceiling is installed on them. The grate is also made from a stainless steel drum - a round blank is cut out with a grinder, and holes are drilled in it.

The upper part is covered with a mesh of steel wire, and a window is cut into the side surface of the cylinder for loading fuel. Legs made of bolts are attached to the cylinder. They can be mounted through protrusions and folds.

Stove made from a placemat and a jar

The device can be made from a cutlery stand. It is sold in household goods stores and is made from stainless steel. There is a cylindrical body with side holes; you need to make an upper grid from wire and secure the legs. A window for fuel supply is cut out in the side surface, and holes are drilled in the bottom. The oven is ready.

A wood chip heater can be cut from a simple tin can with a strong knife or metal scissors. Corresponding holes are cut in the tin, and the upper grille can be woven from wire. Steel knitting needles, thick wire, and so on are used as legs.

How to use such a stove correctly?

There are several rules that will help not only speed up the heating of water or food, but also reduce the risk of overheating of the housing, as well as the severity of the consequences of overheating, that is, thermal deformation and the resulting jamming of parts:

1. For ignition you need to use dry kindling and fuel. After all, it is difficult to ignite wet wood even with the help of a hunting match or dry fuel.
2. The firebox must be completely filled with kindling and fuel, leaving some space for the movement of air and smoke. This will not only speed up ignition, but also reduce the risk of overheating, because you will not have to add fuel until the stove returns to normal operation.
3. If one load of fuel is not enough, then branches and other small wood should be placed behind and on the sides of the heating device at a distance of 2–10 cm. When the wood chipper reaches operating mode, the walls will heat up and begin to dry the fuel. This rule applies to both simple and turbocharged devices.
4. It is necessary to close the door after the smoke rising above the stove becomes colorless. This usually happens 1-3 minutes after ignition.
5. You can put a pot on the stove only after all the fuel has completely ignited and some of it has burned out and turned into coals (usually this takes 5–10 minutes). If you place the container earlier, the stove’s operating mode will be disrupted, which will sharply increase the likelihood of overheating. In addition, if you install the container earlier, it will become covered with soot, and heating a large volume of water will take longer due to the disruption of the combustion regime.
6. If the structural elements are deformed, they must be disassembled immediately after the oven has cooled to a temperature of 70–100 degrees (for this you will need canvas gloves). If you wait until it cools completely, the structure may jam and it will be quite difficult to disassemble it.
7. If any part of the stove is hot and turns red, then you cannot add more fuel. In addition, after cooling and disassembling, it is necessary to inspect this part for defects. If there are defects, the part requires replacement.

Design features

Typically, a cylindrical furnace is made from a pipe or individual parts of a rectangular cross-section. Its height is most often about 20 cm. A so-called grate is constructed in the lower part, and holes are created on the side through which air enters to ensure combustion.

The upper plane is represented by a grate, on which it is convenient to place dishes with food or water. In the other side part, a small rectangular hole is created with a door into which the fuel used is placed. Small segments for skewers are cut along the top edge.

The finished structure is complemented by legs, which provide clearance directly under the grate. The ash remaining after the burnt fuel pours out through it, and air enters. The legs also provide stability to the stove; if not properly supported, it may fall on its side.

Wood chip stove under an army cauldron

In camping conditions, to make a fire you will need to prepare dry firewood, which is not always possible, especially after rain or snow.

An alternative to a fire is a wood chip stove; all you have to do is pour wood chips into the stove, light it, and put the pot on.

1. Making a wood chipper is not difficult; all you need is a piece of tin or thin metal from which you need to cut out the stove parts.
2. Make drawings on a sheet of metal, then use metal scissors to cut out blanks where you need to drill holes with a drill.
3. After that, the workpiece must be attached to the pot and given a shape that follows the contours of the pot.
4. The wood chip stove for the army cauldron is ready for use.

• A reliable, durable pyrolysis stove for use in tourism, hunting and fishing, rafting and in mountainous areas, where there is a shortage of firewood.
• Uses natural traction.
• High efficiency, economical fuel consumption, less firewood is required than on a fire.
• The temperature during the cooking process can be controlled by the fuel supply.
• The fuel for the stove is wood chips, twigs, cones, etc.
• During transportation, the pot is placed inside the stove.
• For transportation, the stove is packed in a case.

Do-it-yourself camping wood chip stove: drawings and photos of step-by-step production of a homemade stove from cans.

This homemade product will primarily be of interest to lovers of hiking; on every hike it is very important to provide yourself with a source of fire to cook food, boil water for tea, and warm up.

You can make a regular fire, but it will take time to collect firewood, and if it rains, then finding dry firewood in the forest and lighting a fire will be problematic.

As an option, you can make a wood chip stove and take it with you on a hike. What are the advantages of such a camping mini stove?

First of all, minimum fuel consumption, which can be used as small wood chips, branches, bark, pine cones, and dry grass. The design of the wood chipper is made in such a way that an air flow is formed in the outer chamber, which enhances the combustion process in the stove.

In fact, with such a camp stove you can heat up food or boil water using just a handful of wood chips, which can be prepared easily and very quickly.

The figure shows an approximate cross-sectional drawing of a wood chip stove.

Next, we look at the step-by-step process of making wood chips with your own hands.

The materials you will need are 3 tin cans, one larger and two slightly smaller.

We take a large jar, mark the places and drill holes in it near the top edge as shown in the photo.

Now let’s put the first jar aside and modify a slightly smaller jar, punch a lot of small holes in the bottom of the jar, and drill holes in a circle around the top edge.

We take this smaller jar and insert it into the larger jar as shown in the photo, fix the jar in the hole of the larger jar (to do this, make a hole in the bottom of the larger jar the size of the inner jar).

The stove is almost ready, let's make a stand for a mug from the third narrow can, the stand is needed so that the mug does not cover the flame of the stove.

We take a shallow jar and drill holes in a circle along the side.

That's all, we made a wood chip stove from cans, I recommend watching the video where the author shows how to properly make and heat this mini camp stove.

Expert opinion Dmitry Timofeevich Tarasov Master of Sports in mountaineering. Author of scientific articles on the topic of survival in the wild

Using a wood chip stove helps out in many life situations. This equipment is especially suitable for hiking conditions and operation in open areas. The country house equipment market is filled with various models of wood chip stoves with individual qualities.

But such a structure can be built with your own hands. The main difference between the choices is that handmade products are guaranteed to have just the right features: simplicity and reliability.

With pyrolysis

Turbo - not turbo?

Homemade supercharged wood chipper

“Turbo” is a catchy slogan, and manufacturers and traders under it launched supercharged chippers to the masses; they are repeated by many amateurs, see fig. on right. But on a hike, it’s enough to be a novice travel companion to understand: batteries for a boost motor are an energy-dependent stove and a completely unnecessary expense. Also, the micromotor and fan are prone to breakdowns in hiking conditions, and the boost pipe sticks out and interferes with proper packing of the backpack. However, hunters, fishermen and tourists, right up to the toughest pros, who go to the “seven” (the route of the highest, 7th, category of difficulty) should not discount the turbo chippers at all.

In fact, a turbo wood chipper is a pyrolysis camp stove, the diagram of which is shown in Fig. below the list; other sizes can be taken proportionally. Fuel is loaded to the bottom edge of the secondary air holes; ignition - from above. American tourists brought the wood chipper to this state. It must be said that careful attention to detail was the strongest side of American technical culture during its heyday; now, alas, there are clear signs of decline. For a solo hike, the pyrolysis stove-wood chipper is too big, but if a group goes, then it shows undoubted advantages:

• A batch of 2-3 dozen pine cones can make lunch for 2-3 people.
• The high temperature zone is concentrated along the axis of the stove (where the flame is in the picture), so a durable pyrolysis wood chipper can be made from cans or thin galvanized steel.
• It can also operate on dry gas hydrate fuel (dry alcohol).
• Without modification, it can be used as a heating system in surface combustion mode, see at the end.
• An overturned burning stove needs to be immediately placed straight so that it continues to work.
• The scattering of sparks and smoldering coals is eliminated, and the bottom heats up to less than 80 degrees, so launching in a tent is possible.

Diagram of the design of a pyrolysis camp stove-wood chipper

The last case is, of course, an emergency. It is necessary to take precautions so as not to get burned, and under no circumstances climb into sleeping bags until the stove has completely burned out and is empty of ash. In addition, if the tent is made of synthetics, you need to put some kind of tarpaulin or something similar under the stove, otherwise the bottom of the tent in that place will become brittle.

Partial pyrolysis

American interest in full pyrolysis in camp stoves is largely due to local environmental regulations; True, outside the zone of its action, tourists there have a terribly ugly attitude towards nature. So, you can collect cones, but you can’t take them from a tree. Raise dry wood from the ground - no thicker than a certain size. In some states and Canada, you can go to jail for breaking off a live branch. And he violated it - in the wildest wilderness, an inspector suddenly appears out of nowhere with an M14 rifle, and then, as in Tsarist Russia: once it comes down to the protocol, it’s a matter of shit.

In the Russian Federation, there are no draconian restrictions on the use of natural resources yet, so domestic hobbyists prefer to make fairly effective, but much simpler structural wood chippers with partial pyrolysis and variable combustion modes. At first, such a stove burns like a flame. As the light fractions of the fuel burn out and its load settles, the role of pyrolysis with afterburning from secondary air becomes increasingly stronger, and the coals burn down to ash through pyrolysis. In terms of efficiency, camp stoves with variable combustion modes are somewhat inferior to pure pyrolysis stoves, but their temperature regime is almost as even and cooking takes almost the same amount of time. All samples considered below (except for the emergency ones at the end) work exactly according to this principle.

How does it work?

The principle of operation of a wood chipper is in many ways similar to the principle of operation of other solid fuel stoves - the fuel found in the firebox, that is, wood chips and small branches or cones, burns, releasing heat, which heats the container located on top.

The same process occurs in wood chip stoves without holes in the side walls, but with a gap between the top of the stove and the heated container.

However, the efficiency of wood chippers is much higher than that of conventional solid fuel stoves, and the reason for this is the excess air supply.

cannot be operated in minimum power mode

Another significant advantage of excess air intake is the almost complete absence of carbon monoxide in the smoke, that is, carbon monoxide (CO), which during the afterburning process turns into carbon dioxide, that is, carbon dioxide (CO2).

Despite the fact that carbon dioxide is also poisonous, its permissible content in the air is almost 30 times higher than for CO. Therefore, you can use wood chip stoves even in tents with poor ventilation systems, although it is better to use them outdoors.

Indeed, even with the most complete combustion of cellulose, carbon dioxide is released, which displaces oxygen from the air, resulting in oxygen starvation, and this can lead to loss of consciousness or death.

Advice from experienced people, or how to choose the right stove

Typically, the first acquaintance with this device occurs when watching videos on the Internet. And everyone is vying with each other to convince them of the excellent qualities of the stove, throwing in scientific terms and background information. But in reality, everything turns out to be much simpler - the dimensions of this device are not the same as those shown close-up on the screen, and the device itself most often turns out to have character.

First of all, don't believe advertising. A standard 300 ml cup placed on the fire looks impressive on the screen, but it is only 300 ml. The second thing you need to focus on is why such a device is being purchased. If there is a need to constantly cook or reheat food, then a collapsible model is better. It is more compact and more convenient to cook on, especially if you need to feed a company of 3-5 people.

But as a multi-purpose stove, it is better to use a stove with a non-separable body. In addition to the wood fireplace, many sets of these stoves also have an alcohol burner. This is a big plus if you need to stay warm in a tent. For long-term burning, you can use paraffin candles here, it can burn for up to 3 hours, or special concentrated dry alcohol, a tablet of which is designed for 1 hour of burning.

It is not necessary to carry dry paper for kindling; it is better to replace it with special waxed or paraffin paper. This paper is not afraid of water, but it lights up very easily and simply.

When purchasing, you should pay attention to such accessories as additional holders and retractable supports; the wider the supports are spaced, the more stable the oven will be. And of course, when using this device, you need to take care of carrying it; branded stoves are usually equipped with a special cover made of fireproof fabric, in which you can hide the stove within 5 minutes after the fire is extinguished.

Folding and non-folding designs - what's the difference?

The main advantage of collapsible models is that the stove, folded and stored in a case, takes up very little space. In most cases, the size of the case with the parts placed in it does not exceed the dimensions of a pack of Belomorkanal cigarettes or a couple of packs of regular cigarettes.

The disadvantage of a collapsible design is that it is slightly heavier than a non-dismountable one, as well as less rigidity, so awkward movement can lead to the collapse of the entire structure, after which it will have to be cooled and reassembled.

The non-separable design does not have these disadvantages, but is noticeably larger in size. Most often, a non-separable design is used to make round wood chippers, which are comparable in size to a thermos with a volume of 0.5–2 liters.

Round stoves are not only stronger and stiffer than rectangular collapsible ones, but also have greater efficiency, because additional air enters the afterburning zone, increasing the efficiency of fuel combustion.

Another disadvantage of non-separable round devices is that they are difficult to heat rectangular or elongated containers, that is, most types of soldier’s pots. There are also round collapsible structures, but even when folded they take up noticeably more space than collapsible rectangular ones.

The remaining parts are turned over and inserted into the lower part, forming a kind of nesting doll. But in round devices, especially with double walls, the supply of secondary air to the afterburning zone is better implemented, which increases the efficiency of the heating device.

Choosing a shape and size

When choosing a shape and size, it is necessary to take into account several parameters , the main of which are:

• firebox size;
• fuel combustion method;
• weight limit;
• size limit.

Firebox size

This parameter affects the amount of fuel that the stove can hold, and therefore the amount of thermal energy it will produce as a result of combustion.
The parameters of the firebox directly affect the efficiency of the heating device in various conditions - the smaller it is , the slower a certain volume of water will heat up .

In other words, a device with a small firebox is suitable for serving by one person. You can boil a mug of tea on it or heat up a can of stew.

more fuel into the stove than the volume of the firebox allows will lead to rapid overheating and damage to individual parts.

To serve a company consisting of two or three people, the most effective volume of the firebox will be 1 dm3, that is, a cube with a side size of 10 cm. For a company of 3-5 people, a cube with a side of 15 cm will be optimal.

These values ​​are only guidelines and do not have to be strictly followed. In addition, even a small stove with a firebox size of 1 dm3, if used correctly, can provide food for 3-4 people without deformation of parts, although you will have to use instant products and spend more time heating water.

Pyrolysis and conventional methods of fuel combustion

There are 2 main ways of burning fuel:

• ordinary;
• pyrolysis.

For normal fuel combustion, it is enough to make the most primitive metal box, which will direct the bulk of the pyrolysis gases and flame upward.

The efficiency of this method of burning wood is low , and due to the high content of unburnt cellulose particles that have turned into soot, the surface of the water container becomes covered with soot and turns black. Therefore, the only advantage of the conventional combustion method is the simplicity of the design of the heating device.

, thermal decomposition of wood occurs with a partial lack of air and a small amount of fire.

Then, in the so-called pyrolysis block, the smoke is mixed with secondary air, which enters through the holes in the stove body, and afterburning occurs. That is, part of the carbon monoxide (carbon monoxide), which is formed during the thermal decomposition of wood, is converted into carbon dioxide with the release of thermal energy.

With this burning method, the cellulose that makes up the wood burns more completely, releasing more heat , so less fuel is needed to heat the same amount of water.

In addition, the pyrolysis method is better suited for raw wood, but the main type of fuel for such stoves is what can be picked up underfoot, that is, branches, bark and cones, which in most cases have a fairly high humidity.

Weight and size limit

Those who have gone on multi-day hikes over long distances know how much stuff and food they need to take with them, and understand the importance of every extra gram. For such tourists, the weight of the wood chip stove is the determining factor.

The weight depends not only on the design and size of the heating device, but also on the thickness of the metal from which the stove was made. Therefore, you have to choose between the thickness of the metal and the weight limit.

The thicker the metal, the easier the stove can withstand accidental overheating (this is only true for steel, so parts for titanium camping heaters are made very thin, that is, 0.4–0.6 mm).

On long hikes, it is very important to use the most compact things possible, because the volume of a backpack is limited, and you need to take a lot with you.

In such conditions collapsible devices are preferable , because when folded their size does not exceed the dimensions of a not too large book or tablet.

However, this type of heating device is noticeably more difficult to manufacture and slightly less efficient. If there is no strict size limitation , then it is better to choose a non-collapsible or partially collapsible design.

Manufacturing options

With a certain set of equipment and skills in working with metal, making a wood chip stove will not be difficult. There are several current options.

From the drum of a washing machine

It’s possible to adapt a worn-out washing machine into an excellent outdoor fireplace. To install the stove you will need a washing machine drum. The holes around the perimeter of the drum will provide a constant flow of oxygen and also serve as decoration.

The diagram shows the possible dimensions of the manufactured furnace.

Materials and tools:

• Drum.
• Angle grinder and grinding wheel.
• Wire brush.
• Cutting wheel for metal.
• Metal corners and flat workpieces.
• Heat-resistant paint.

Instructions:

1. First you need to remove the drum and remove all dirt. You should also clean the rim of any plastic parts.
2. Cut off the main spindle and the fold at the top to make the piece look better.
3. Use a sander to remove any uneven surfaces at the bottom.
4. Remove any remaining old foam.
5. Make legs from fasteners so that the stove is at a distance from the surface.
6. The final stage will be painting the stove.

   Wood chips from a washing machine tank

From the cutlery stand

Using an ordinary cutlery stand you can make a simple wood chip stove. The design will last a long time, because This kitchen item is made of food grade stainless steel with thick walls.

To make such a structure, you need to take:

• four bolts with nuts.
• metal rods.
• marker for marks.
• Bulgarian
• steel partitions, metal chain (optional).

Instructions:

1. The legs will be bolts that need to be attached to the bottom of the stove. The rods are inserted through the upper holes. This is how you get a tray for dishes.
2. The system can be improved using a variety of stands. To do this, four markings are made on the rim of the stand and cuts are made using a grinder. The cross stand is strengthened into the formed grooves.
3. The same action should be performed with the bottom of the stove. This is necessary for the formation of greater lift and good access of oxygen.

Option 1

Option 2

From a can

A good solution for tourist events can be the use of a wood chip stove made from cans. The advantages of this design are that assembly requires a minimum set of tools and a small amount of time.

To work you will need:

• Two tin cans of different diameters.
• Knife.

Manufacturing instructions:

• To begin with, in a smaller jar you need to make holes at the bottom and sides, near the rim.
• Then take a second can, make holes along the rim and remove the bottom.
• Insert a smaller jar into the hole formed.
• Make a stand for the heated dishes.

  Stages of making wood chips from a can

This stove would be an ideal solution for use by one or two people. Despite the simplicity of the design and small dimensions, a fairly strong hearth is created in a stove made from cans. It is also worth noting the environmental friendliness of such equipment.

Foldable design

The folding camp stove-wood chipper is compact and easy to carry.

To assemble such a stove you will need flat metal parts. When assembled, the folding stove looks like a small square package. It should be remembered that the corners of such a product are sharp, so folding wood chip stoves must be placed in a special bag or container.

Materials and tools:

• Sheets of steel (no thicker than 2 mm) and wire (no thicker than 3-4 mm)
• Metal hacksaw, file.
• Drill, hammer, for bending steel.
• Pliers
• Bench punch.
• Suitable fasteners.

Drawing:

Manufacturing instructions:

• Using the drawings for making a wood chip stove with your own hands, you need to make a plan on a paper sheet.
• Transfer the design to the metal and correctly cut out all the necessary elements.
• Drill holes for the wire on all parts of the walls of the future stove.
• Using wire, assemble the walls and bottom of the stove.
• Make a mesh for dishes.

  Parts assembly diagram

It is not difficult to make such a unit with your own hands. The advantage of this design is obvious: the stove is easy to assemble, like a construction set. Using the drawings greatly simplifies the construction of a wood chip stove with your own hands. Basic skills and tools will allow you to create an always-in-demand structure for heating and cooking food in camping conditions.

Difference from other types of heating devices

Here are the main differences between this device and analogues operating on other types of fuel:

1. The main purpose of a wood chip stove is to quickly heat a small volume (1–5 l) of water . Thanks to the design, the fuel burn time is 10-30 minutes, which is quite enough for boiling water or quickly preparing food, such as a small batch of sausages or mushrooms.
2. Small dimensions , comparable to portable stoves designed for other types of fuel, allow you to take this device on hikes. When assembled, it is comparable to an army bowler hat, both used by conventional troops of the Soviet and Russian armies, and the legendary Airborne Forces bowler hat, model 1959, and fits perfectly in size. When disassembled or in transit, its size is only slightly larger than a tablet or smartphone.
3. Even the most primitive wood-burning stove is more complex and contains more parts than this device. After all, there are no grates, no blower or other parts necessary for the normal operation of a wood-burning stove, and there is also no complex fuel equipment. Due to the simplicity of the design, assembly takes a few minutes and even an inexperienced tourist can carry it out.
4. The wood chipper is lighter than most other stoves. The walls and other parts are made of titanium, stainless or tool steel with a thickness of 1–2 mm, and many parts are perforated to create a pyrolysis effect. The thickness of titanium parts is a fraction of a mm. If the parts are made of steel, then the smaller their thickness, the more they are afraid of high temperatures. Therefore, the thicker the part, the less likely it is to deform.
5. Economical . By taking a few thick, dry branches with you on a hike, you will be able to use this heating device for a long time, because 100–500 grams of fuel is enough for a single load.
6. Due to the simplicity of the design , it is not difficult to make it yourself , which we will discuss in detail in this article.

Wood chip stove diagrams, drawings

Thanks to its compact size, the stove does not take up much space and weighs little. This compares favorably with a gas burner, for which gas cylinders are required. The total weight of the burner with cylinders reaches several kilograms

.
A wood chipper weighs about a kilogram, depending on its design .

Photo 1. Drawing of a square wood chip stove. Contains four parts, the dimensions of each element are indicated.

The design is easy to make yourself from available materials.

For one person it is made from a large tin can. The larger version is assembled from the drum of a used washing machine.

Photo 2. Drawing of a cone-shaped wood chip stove. Such a device can be folded like an accordion.

sheet metal is suitable as a material

There are several types of structures. They differ in form and scope of application.

Important! All devices have air intake holes at the bottom. This ensures good traction and fuel combustion

First: stove under the pot

This option is intended for use on hikes

, mainly in singles.
Most tourists have a standard size army bowler hat. The oven is made for it. The shape of the wood chipper is similar to a cooking container
. This design option is the lightest.

Reference.

The dimensions of the stove are selected in such a way that the pot fits without a gap.
Then it heats up faster, since the heat does not escape out through the cracks. To make adjustments, a drawing of the bottom is made by tracing the lid of the pot with a flange
.

Second, square

Most cooking utensils are still round in shape, so the previous option is not suitable for it. A square-shaped wood chipper will come in handy both on a hike and at the dacha

If you make it collapsible, the device will be more convenient to transport and store. Dimensions are increased proportionately if necessary.

The shape of the holes in the side walls can be any.

Third trapezoid

This wood chip stove is also foldable, but it is assembled like an accordion, rather than being divided into separate parts. It differs from the previous one trapezoidal shape.

Such a stove is more stable; the heat in the device is concentrated in the central plane.

If the top of the structure is made too narrow, some of the heat will be lost through holes in the upper side of the walls. The device weighs approximately about a kilogram.

Petrol

Advantages:

• has high heat transfer;
• operates at any temperature, which is especially important for use in “cold” travel conditions;
• very accessible because it can be poured into a canister at any gas station or even from the tank of a passing car if you find yourself in a region remote from civilization and gas stations;
• gasoline is quite cheap.

Minuses:

• Gasoline is very fluid, its vapors are very volatile. It is able to penetrate through blind plugs, gaskets and sealants. You cannot transport gasoline in absolutely all types of transport that take you to the beginning of the route: on planes and trains;
• the smell of gasoline can permeate all things in a backpack and tent, including food. That is why, often on hikes, one tourist is appointed as a “fuel carrier”, who does not carry either food or public equipment in his backpack, because... they may smell like gasoline;
• gasoline is explosive and fire hazardous;
• to ignite a gasoline burner, you must first provide fuel supply using a pump, and these manipulations require skill and time, which is not particularly pleasant in the cold and wind;
• Poor quality fuel (low octane number) can clog the burner and render it unusable.

The best ready-made models

Ready-made stoves can be purchased on any suitable website or in construction stores. Another interesting solution would be to buy a stove from the well-known Aliexpress website.

Turbo oven PS1500T

This option showed excellent results at low temperatures.

The stove does not require large supplies of firewood and saves a lot of time and effort. The blower in the furnace system allows you to gain high power in a matter of minutes. Even raw wood can be used as fuel.

The PS 1500 T turbo stove kit includes the following parts:

1. electric air blower,
2. stainless steel housing,
3. the combustion chamber,
4. stand.

The supercharger runs on two AA batteries. Operation is possible in three modes:

1. High fan speed (3000 rpm).
2. Low fan speed (1500 rpm).
3. Off — when switching off, the supercharger must be removed to avoid overheating. In this case, the oven will continue to operate thanks to natural draft.

On one set of alkaline batteries, in different modes, the oven will work for about 50 hours.

The price range of the PS 1500 T turbo oven is 2500-3000 rubles.

Folding

The next most popular wood chip stove is a camping and country folding one. Such wood chippers are assembled into a working configuration from flat parts, which when folded form a compact package. It is placed in a cooking container or in a special pocket inside the backpack so that the corners do not tear anything. Due to its compactness when folded, parts of the folding wood chipper can be made from ordinary structural steel with a thickness of 1-2 mm. The weight of installation in the stowed position then increases to 0.8-1.2 kg, but the stove turns out to be quite durable without the use of special steels. In addition, the same approach allows you to make a summer wood chipper of increased size, on which you can cook lunch for everyone in a cauldron or boil a bucket of water.

• Parts 1 are moved slightly apart and pushed down until they stop;
• Det. 4 is raised and Parts 1 are brought together so that its wings c' fit into the cutouts c of Parts 1;
• The stove is fixed in assembled form by putting Part 3 with its grooves d' onto the hooks d of Parts 1.

Folding country house

A country folding wood chipper must, firstly, withstand a significant load. Secondly, with its increased dimensions, it becomes difficult to ensure a variable combustion mode by simply drilling holes in the sidewalls. Thirdly, a country wood chipper should make it possible to place dishes of different sizes on it, and at the same time, the requirements for maximum compactness when folded and minimum weight are not necessary for it. In Fig. Patterns of the sidewalls of a country wood chip stove that meet these conditions are given; side of the square of the scale grid - from 10 to 50 mm, depending on the purpose of the furnace and the availability of material.

Patterns of parts for a folding country stove-wood chipper

Material – structural steel with a thickness of 1.5-2.5 mm. The red-filled blades of the sidewalls, forming the burner, bend inward at angles of 45 degrees after cutting out the blanks. This ensures, firstly, the possibility of installing vessels of various sizes on the burner. Secondly, together with the shaped cutouts at the top, the dimensions and configuration of the bottom of the installed vessel, the flow of secondary air is regulated, i.e. This stove is self-adjusting according to the cooking utensils. If you put a frying pan or a small saucepan, it will burn longer, but heat less. Under a large cauldron with a rounded bottom it’s stronger, under a bucket it’s even stronger, and under boiling water it’s generally at its maximum.

Folding pyramidal wood chip stove

About pyramidal wood chippers

Sometimes amateur designers, in order to achieve more complete combustion of fuel, make folding wood chips of a pyramidal shape. Indeed, in such furnaces the share of pyrolysis in the heat release increases. But the additional heat is easily lost, as can be clearly seen in Fig. on right. The stove is not a cooling tower after all.

Main advantages

In comparison with a pyrolysis furnace, a wood chipper can function when damp fuel is placed in it. This explains the increased interest in it from tourists. For example, in winter it is quite difficult to find dry cones or branches in nature. The following advantages exist:

1. The ability to quickly and economically prepare food in areas with an acute shortage of firewood. In such a stove, not supercharging is used, but natural draft.
2. Due to the clever design of the device, almost all the heat generated during the combustion process is used to heat the installed cookware.
3. There is no need to build a large fire to heat the kettle. Instead of firewood, cones, twigs, and chips are suitable.

In extreme conditions, there may be a vital need for heat for warmth, heating water, creating food with minimal fuel available. The wood chipping camping stove can be used even inside a tent without danger to humans.

The device will be appropriate on a personal plot in the summer, because you won’t have to run a house stove, build an outdoor version of it, or waste gas. A similar dacha stove when folded weighs no more than 2 kg with a volume of about 2 cubic meters. dm. It is suitable for quickly preparing soup for a family of several people. The camping counterpart, designed for quickly preparing one serving of food, is several times lighter, and when assembled it takes up about 0.3 cubic meters. dm.

There are no costs for high-quality long-burning material. If the purchase is carried out, then the amount does not exceed several hundred rubles. In most cases, a person makes do with improvised and free devices. As for a gas all-weather burner, it will cost from 1000 rubles. A special cylinder of 3 liters or more is purchased for it, but the total weight of the load will be from 5 kg.

The main pros and cons of a wood chip stove

It is reasonable to consider the effectiveness of a wood chipper in two planes. In the first plane, compare its efficiency with other designs of camp stoves. In the second plane, it is worth analyzing how effective small-sized stoves themselves are in their class, ranging from full-body ones to turbocharged devices.

Comparisons of wood chips with other designs

Many innovations can be incorporated into the design of an ordinary camping stove, but in terms of energy efficiency, it will be possible to increase the efficiency only by using the technology of afterburning pyrolysis gases. In this case, the design turns out to be unreasonably complex and quite heavy. At the same time, such a stove will perform the function of heating water and cooking food rather difficultly; too much energy is needed to heat the body itself. Plus, it will not be possible to immediately raise the temperature in the firebox to the required 450-600 degrees to start decomposing the wood into light gases.

With an open fireplace, everything is much simpler; here, thanks to the small size of the fuel particles, the wood heats up faster and the process of burning light gases begins. The combustion process itself does not spend a large amount of energy to heat the metal body, but immediately releases heat to heat the cooking container.

The efficiency of wood chippers among mini-kilns

When it comes to efficiency among the mini ovens themselves, ovens with a non-removable body have many advantages over folding ovens and fan-powered super ovens. Of course, models equipped with a turbine reach maximum combustion mode faster, but the question is how long the batteries will be enough to power the electric motor. Collapsible models are convenient for preparing dishes where fire is required for a long time, for example more than 30 minutes. But in terms of quick heating or making tea, a stove with a non-separable body is still more effective.

The advantage of this model lies in the specific shape of the firebox and the channels through which air enters the hearth. The firebox itself, representing a metal glass, supports combustion in the upper part, the incoming oxygen through the channels between the hearth and the outer body is heated and enters the combustion zone at a temperature of 100-150 degrees, this is quite enough for the process of releasing flammable substances to proceed faster. Thus, already 3-4 minutes after the wood begins to burn, the temperature rises to 350-450 degrees.

Design and principle of operation

The primitive wood chip stove system operates on a burning flame. The principle of operation of such a device is long-term combustion. The main advantage of a flame-burning stove is that you can use fuel that burns difficult - solid fuel (branches, roots, etc.). The efficiency in this case is low, because the work uses oxygen, not gases.

Such a device can be constructed at home in a short time. A high-quality DIY wood chip stove must use pyrolysis. Such stoves are economical and practically omnivorous. A wood chip stove that operates only on the decomposition of natural compounds is called a turbo wood chip stove.

Fuel consumption in this equipment occurs only with a certain amount of air. A diagram of the operating principle of this stove is presented below:

At the first level, there is a full supply of air, then, after about 10-15 minutes, it quickly decreases. The oven enters the smoldering stage. At the same time, even gases produce energy.

This camp stove does not have a convenient shape, but it has many useful characteristics:

• The fuel can be dry fuel.
• With a small amount of fuel you can cook food for several people.
• Even if the basis of a pyrolysis stove is a tin can, the device will still last a long time. High temperatures accumulate on the axis of the unit.
