Do-it-yourself oven for a cauldron from a pipe: simple and very affordable manufacturing methods Ovens for a cauldron: principles of arrangement and cooking, purchase, construction on their own A stove from a propane cylinder for a cauldron

Rarely is a picnic complete without cooking on a live fire. Basically, this, of course, is meat and everyone's favorite kebabs, but it happens that you want to cook some kind of porridge or soup. This is especially true for overnight trips. A cauldron is considered an ideal dish for such purposes. It can be installed on a tripod over a fire, but in this case, cooking pilaf or stew will “pull” a lot of fuel. And you can make a small stove and cook with convenience.

Convenient stove for a cauldron: its device and materials of manufacture

Kazan is a large camping pot made of cast iron with a semicircular bottom. It is this shape and rather thick walls that allow food to warm up as much as possible and not burn. In addition, the products in the cauldron are stewed evenly, which gives the dishes a simply divine, incomparable taste.

For such a cauldron, a special Roman oven is suitable, which will make the cooking process more convenient. Its main difference from other devices is the hole for the pot in the stove itself.

The width of such a hole should be such that the cauldron is placed 2/3 below the level of the tile. If you overdo it and make the hole too big, then it will be very inconvenient to get the dishes, and if already, then the surface of the dishes will heat up unevenly.

However, today plates with rings of different diameters are already on sale so that pots of any size can be used.

You can create a stove for cauldrons with your own hands from:

bricks;
car rims;
gas cylinder or pipe;
metal.

Homemade brick oven for a cauldron

A brick stove for a cauldron can become not only a place for cooking, but also be a kind of decorative element.

To create an oven you will need:

Chamotte brick;
Bulgarian;
Floor slab about 2 cm thick;
Steel corners;
Grids;
Sand;
Two doors.

The stove itself should be slightly raised by about 80 cm.

The procedure for creating a furnace:

Creating a foundation - since the weight of the stove is small, it makes no sense to build a full-fledged foundation. Therefore, the base is simply poured with concrete and reinforced with reinforcement. First, formwork is made, which is poured with a solution of sand, fireclay powder and water with a layer of 80-100 mm and leveled with a building level. Next, reinforcing bars are inserted into the concrete, between which there should be gaps of about 10 cm.
Laying out walls - laying bricks is done with dressing the seams: the initial row is half a brick, the second is a whole, the third is half again and so on. All metal elements are placed in the course of creating the stove.
Installing the door - for this, a wire is mounted in the wall, the ends of which are clamped between the bricks and fixed with mortar.
Installing the grate - this should be done immediately after closing the door of the ash drawer.
Laying the firebox - this should be done from durable fire-resistant bricks. The firebox itself should be in the form of a cylinder, placed vertically and cut off in front.
The construction of the chimney - in the upper part of the furnace, you need to leave an opening for the removal of smoke.
The final stage is the installation of corners and laying the slab with a hole for the cauldron. After that, you can embroider the seams and tile the stove.

After completing all the work, dry the stove thoroughly and dilute the hearth for verification. On the device you can put a cauldron filled with water. If the air bubbles that form before boiling are evenly distributed, then heating will also occur.

Do-it-yourself metal oven for a cauldron

For outings into nature, a metal portable stove-potbelly stove is ideal, which is convenient to take with you and use where you need it. The material for such a device can be a pipe or an old 50-liter gas cylinder.

Before using the cylinder, you need to make sure that there is no gas in it! To do this, open the tap and let the balloon stand for about a week in the fresh air. This is enough for the rest of the gas to come out. After all, even a small amount of it can lead to negative consequences when cutting the product.

The procedure for creating a stove under a cauldron from a gas cylinder or pipe:

First, the balloon is cut into two parts. The cut line can run approximately 20 - 25 cm from the top edge of the product. To get a straight line, you should first wind a paper tape around the balloon, and then cut along it.
Further, the lower part is placed vertically, and a cauldron is installed on it. If the diameter of the oven is not enough to place dishes in it, vertical cuts of about 5 cm are made from above in increments of 10 - 15 cm. After that, you need to check again the fit of the cauldron to the stove.
At a distance of about 15 cm from the bottom of the cylinder, a hole is cut out for laying fuel. It should be wide so that there are no problems with laying firewood.
On the back side at the top of the stove, you need to make a hole for the smoke to escape. For better traction, you can attach a metal pipe.

The metal stove for the cauldron is ready. It remains only to ignite it to get rid of unnecessary odors.

Practical do-it-yourself oven for a cauldron from disks

The easiest way to make a stove for cauldrons is to use car rims.

The workflow looks like this:

Unnecessary disks are prepared and with the help of a grinder a partition is sawn off on one of them;
Next, the disks are placed one on top of the other - the disk with the partition should be at the bottom;
Discs are welded together;
Holes for doors are cut out, handles and a stand are welded.

Here is such a simple and original way to make a stove from improvised materials.

By the way, if another quick method is to build a stand for a cauldron from an old unnecessary bucket.

So, to make a stand you need:

Knock out the bottom of the bucket;
Then, next to the former bottom, make several small holes for smoke;
Next, near the wide part of the bucket, knock out a small door for laying fuel;
Turn the bucket upside down with its narrow part, that is, upside down;
Put a cauldron in place of the former bottom, lay firewood through the door and make a fire.

Do-it-yourself oven for a cauldron from a pipe or how to conquer oriental cuisine without leaving home

Oriental dishes are not only incredibly tasty, but also very healthy., as evidenced by the numerous longevity records held by Asians. The main secret of the presence of qualities so important for food is a peculiar way of cooking, which consists in using a special dish called a cauldron and a special oven. And if the first can only be bought, then the second is quite within the power to create with your own hands, which I will tell you in detail.

Getting Started

I note right away that a suitable oven can also be laid out of brick and smeared with clay. This is exactly what is often done in the countries of Central Asia.

As you can see, in this case, a special round ring is also created for convenient immersion of spherical dishes. But personally for myself, I still chose the option of a metal pipe for the following reasons:

Simplicity and speed of manufacture. Of course, you will have to work, but the whole process will take much less time and effort than the construction of brickwork;
High heating rate. Brick keeps heat longer, but you don’t need to heat the room. The steel shell will create the necessary temperature conditions much faster, at which it will be possible to start cooking;
Compactness and mobility. The metal structure takes up much less space and can be easily transported to any place on the site or even to the utility block during your absence;

Low selling price. You will most likely be able to find most of the materials at your own dacha, which will significantly save the family budget.

A do-it-yourself oven for a cauldron from a pipe is made in three stages:

Step #1: Preparing Tools and Materials

From the materials you will need:

Fragment of a large diameter pipe. This will actually be the main "body" of the future furnace. It is best to find such a product left after any construction work, of course, on your own site, but if you don’t find a suitable piece among your stocks, then you can look for it at virtual “flea markets”, for sure someone turned out to be more thrifty at one time .
As a last resort, you will have to go to a specialized store, but keep in mind that there, most likely, there will be segments much longer than you need and this will lead to an overpayment;

Fragment of a pipe with a cross section of 100-150 mm to create a chimney;

Several iron corners or profile tubes to create legs;

Grid or steel sheet to create a bottom.

From tools:

Electric drill with drills for metal to create the necessary holes;
Angle grinder for cutting iron products;
Welding machine for connecting the main fragments of the furnace. This is the most expensive of the tools required to create a furnace for a cauldron;

Welding machines are quite expensive "pleasure". Therefore, if you do not have such a unit on the farm, I recommend not buying it for one-time use, but renting it, which will be much more economical.

A hammer, without which I personally do not start any work at all;
The spirit level in order to make the design even.

Step #2: design

At this stage, there are several important decisions to be made:

Will you pick up a pipe under a cauldron or, on the contrary, a cauldron under a pipe? It mostly depends on what you already have in stock. But the main thing is that as a result the dishes are immersed in the oven body by two thirds or even along the upper border. Otherwise, for its full warming up, an irrationally large amount of firewood and time will be required;

Do you plan to install racks? You can also install the structure on the ground, it just becomes higher then, and the fire itself is lit right on the ground. If you attach legs, which is much more aesthetic and functional, then in this case you will also need to weld the bottom to the bottom of the pipe;
Who will use the oven most often? The height of the racks depends on this. That is, if you are personally going to engage in oriental cooking, then in the process of cooking you should not bend down, and racks should be under your height;
How much to cut the prepared pipe section? To obtain the highest efficiency, it is necessary that the distance from the combustible firewood to the bottom of the cauldron does not exceed 300 mm. Under such parameters and adjust the steel cylinder;
Are you going to move the oven from place to place? Since the choice fell on a metal structure, then most likely the answer is yes. Then don't forget the pens, the size of which should correspond to the dimensions of the palm;

As a result, you should get something like the following drawing:

Step number 3: assembly work

Now let's start assembling the prepared materials into a single useful structure that will allow you to join the wonders of oriental cuisine right on your own lawn:

We apply all markings according to the draft;
We cut off the excess part of the pipe with the help of a grinder. After that, be sure check the horizontal and vertical of the resulting cylinder with a spirit level;

Closer to the bottom, cut a furnace hole. Its shape can be either rectangular or semicircular, depending on your taste, but this factor does not affect the functionality. The separated piece should not be thrown away, since in the future it can become an excellent door or damper;

Never use an angle grinder without a protective cover.
Not only can sparks and dross fly in your face, but there is also the danger of a disc rupture, the fragments of which can cause very serious injuries.

Now flip the cylinder and at a distance of 100 from the top edge, create a hole for the chimney appropriate diameter;
Using a drill or the same "grinder" on the sides of the structure, we make several ten-millimeter through openings. Thanks to them, the fire will be able to receive the necessary amount of oxygen;

Don't make the air supply points too high, as the smoke coming out through them will sting your eyes unpleasantly and interfere with the cooking process.

Using a welding machine, we weld the chimney part from two pieces of pipes connected at a right or obtuse angle. Here you can apply a “knee” for them or cut the edges at 45 degrees or less, be guided by the situation;

The resulting the chimney is welded to the hole cut on the body;
Now we mount corners or profiled pipes as legs. You can use both four and three supports, the main thing is that an equal distance is maintained between them, and the furnace as a result is quite stable;
We make the bottom of the lattice or solid metal sheet;

We fix the handles at the top of the structure;
On one side of the firebox and on a piece of metal set aside, we drill a couple or more holes through which we pass a wire that acts as loops. So you get a homemade furnace door, to which you still need to attach a handle;
We clean all burrs and eliminate other possible design flaws;
We apply oven varnish or fire-resistant, after which we can consider the work finished.

But there is no limit to perfection, and the design you made can always be improved. Here are some of the ways:

Possibility of using cauldrons of different diameters. This is done very simply. It is enough to weld a ring on the upper edge of the stove, the outer diameter of which will correspond to the cross section of the cylinder, and the inner one will be suitable for installing rings from a standard wood-burning stove. Thus, by adding or removing them, you can adjust the width of the outlet for different dishes;

Blower implementation. To do this, it is enough to place the grate not at the very bottom, but a little higher, and make an additional door for the lower compartment. This will greatly improve the performance of the furnace;

Creating a stand for a cauldron. This is not exactly an improvement on the design you created, but rather some useful addition to the process of its operation. Having built a high ring on which it will be possible to install spherical dishes, you can at any time take it off the fire and put it on a flat surface. For this, a pre-made segment from the main pipe is quite suitable.

Gas cylinder stove

Many summer residents may have used gas bottle, so why not use it as a pipe? Moreover, he already has a bottom. The workflow here is very similar to the one described above, but it has some differences:

Elimination of residual gas. Previously, there was a combustible and explosive substance in the cylinder, remember this! Therefore, before starting work, open the valve and leave the product for several days to exclude the possibility of a tragedy;

Marking. This procedure is similar to that which is carried out when creating a furnace from a pipe;
Creating a firebox. We cut the desired hole with the help of a "grinder" according to the applied lines. Here, again, you can make any form at your discretion, the main thing is that it is convenient to lay firewood;
Oven Height Adjustment. According to the markup, cut off the top of the balloon. If necessary, we bend the “petals” of the edges so that the cauldron is at the optimal distance from the hearth during cooking;

Installation of functional accessories. Here we are talking about legs and handles, with which it is much more convenient to operate the structure, and it will also look more aesthetically pleasing;
Internal firing. You can do without painting, but it is necessary to lay firewood and ignite the inside to remove the remnants of unpleasant residual odors before you start cooking.

Conclusion

After you build the oven, you will finally have a great opportunity to practice the culinary delights of the East. It is especially pleasant that the described method allows you to get by with minimal costs of finance, effort and time. So go ahead, please yourself and your loved ones with delicious and healthy oriental dishes.

Many lovers of various methods of cooking on fire often use a cauldron, barbecue, grilling or smoking.

But we will talk about a cauldron, and not a simple one, but made with our own hands from a gas cylinder.

Kazan and its features

Mankind has been using a cauldron for more than one century, this device arose even long before the advent electric and gas stoves. For cooking in this vessel, you need a live fire and the simplest and most functional hearth. The cauldron has a spherical bottom and thick walls. Therefore, stability on a flat no need to wait for the surface. The round shape suggests a stand in the form of a ring. It's not worth trying place it on a regular grid for grill or on .

A boiler with a flat bottom warms up faster from below, but a cauldron makes it possible to distribute this process evenly. Plus, thick steel is used for manufacturing, and in in most cases - cast iron. Get the right pilaf in a flat-bottomed pot or in a conventional saucepan with a thin bottom, is unlikely to succeed. Only a cauldron will be able to please you with an amazingly delicious and exotic taste of an oriental dish prepared with your own hands.

To cook goodies in a cauldron, you need a good oven, and not some kind of stand on a fire, a stone structure or a primitive tripod. Of course, a solid one would be ideal, but, unfortunately, country conditions dictate the need for a mobile and compact product that you can buy or make yourself without resorting to additional help. It is worth noting that there is also an opportunity to save significant funds, get additional experience and with interest to spend time. Summer conditions allow make your own oven from a waste gas bottle.

Attention! It is extremely important to get rid of all residues and deposits, accumulated during operation. This can be done in many ways, but a more reliable way is to flush the bottle with water using a high pressure pump.

Step-by-step instructions for constructing a furnace from a gas cylinder

We check the cylinder for the presence of residues, since if there are any there is a danger fire or even explosion. The easiest way is to leave it outside with the faucet open for a week or two.
We outline the cut line using a marker to make it clear. To do this, we deviate from top 20-25 see at your own discretion. Next, we will use the lower part with the bottom of the cylinder for the base of the stove for the cauldron.
With the help of a grinder make a neat cut, after which we try on a cauldron. The ideal option would be when the cauldron will be fit on 2/3. If the cauldron has a larger volume, it is necessary to make vertical cuts with the help of a grinder about 5 cm from the top, every 10-15 cm and, if necessary, bend.
We measure from the bottom 15-20 cm. and cut out an opening for placing firewood. It must be made wide enough so that in the future there will be no difficulties with throwing firewood or cleaning from the remnants of combustion products.
On the opposite side of the furnace window, a few centimeters higher, you need to make a round hole of a small diameter (about 15 cm.) to release combustion products. Ideally, you need add metal pipe, the diameter of which will correspond to the hole in the furnace, which will make the draft stronger. To increase traction, if necessary, you can make an inverter type output. This will require a smaller diameter pipe and a little time. Thanks to this implementation, traction will be provided in all weather conditions.
Now you need to try on the cauldron and, if necessary, enlarge the incisions or straighten them slightly. It is necessary to achieve a snug fit to ensure the fastest warm-up, and respectively, and fast cooking.
Having completed the manufacturing process, we calcine the furnace so as not to leftover odors and old paint.

Homemade metal stoves are good because the material for them lies under your feet somewhere in the garage or in the backyard. A productive heater can be built from scraps of rolled steel or a finished container, for example, a household or automobile gas cylinder. Propane and methane vessels are made from high-strength alloys and require a minimum amount of modifications, which is why they most often attract the attention of home craftsmen.

Features of heaters from a gas cylinder, their pros and cons

A furnace built from a propane or methane tank will always be more productive and more economical than a rectangular metal one. This is due to the cylindrical shape of the cylinder and the configuration of the furnace.

The stove built from a gas cylinder can be used not only for heating the room, but also as a cooking stove

Its spherical surface and the ratio of height to diameter contribute to the pyrolysis combustion of solid fuel, and this is the key to thermal efficiency. It is also known about other advantages of gas storage vessels as the basis of a home-made furnace:

for the manufacture of cylinders, high-quality steels with additives of alloying elements are used. They perfectly resist corrosion and have high heat-resistant properties - the metal will not burn out even after many years of operation;
the rigidity and strength of the heat generator are provided by the mechanical strength of the gas vessel itself;
the cost of a new domestic gas cylinder is less than 2 thousand rubles, and the old one will be free of charge;
conversion of a tank for propane-butane or methane into a full-fledged heat generator will require a minimum of effort and time;
optimal shape and size;
variety of designs;
a cylindrical vessel is well suited for the manufacture of pyrolysis heat generators;
The optimal surface area of the stove allows you to heat up the room as quickly as possible due to both convection and radiation.

The disadvantages of a furnace made from a gas cylinder include:

high surface temperature;
increased requirements for the placement of the device and compliance with safety regulations;
the complexity of adjusting the heating temperature due to the high inertia of the solid fuel combustion process;
low heat storage capacity of the heating unit;
painting gas cylinders with ordinary enamel, which burns out when heated, releasing caustic substances that are unsafe for health into the room.

Almost all negative aspects are eliminated by the modernization of furnaces. So, to regulate the air supply to the combustion zone, thermostatic draft regulators are used, and to preserve heat, the stoves are dressed in brickwork or equipped with a water jacket.

Thermostatic draft regulator allows you to change the degree of opening of the blower depending on the thermal regime of the furnace

Variety of designs: which one to choose

Depending on the purpose of the furnace from gas cylinders can be divided into several groups:

heating and cooking appliances that are intended for installation in residential premises. Often they are equipped with a water jacket and used as the main heat generator of a country house or cottage;
potbelly stoves for heating storage, utility and other non-residential premises;
cooking appliances;
small-sized heating and heating-cooking furnaces of a portable type.

The most difficult of them are stationary units, which is due to increased requirements for thermal efficiency and economy. Nevertheless, there are designs that are not inferior to industrial designs both in terms of performance and operational safety.

Simple potbelly stove of direct burning

All that is needed to make such a stove is a gas cylinder, a chimney and a few scraps of unnecessary pipes and corners. The role of the loading door is performed by a part of the cylinder obtained during the arrangement of the furnace opening, and the grate is replaced by slots or holes in its lower part. In this case, the balloon is placed vertically or horizontally. When choosing a design, it is taken into account that the first option takes up less space, and the second has increased heat transfer.

The potbelly stove is the simplest heating device

Long-burning heaters

The duration of operation of these units determines the method of burning solid fuel, including both conventional combustion and pyrolysis. The design requires the arrangement of an afterburning chamber, therefore, to build a heater, you will need a cylinder with a capacity of at least 50 liters. The advantage of long-burning stoves is that not only firewood and coal can be used as fuel, but also any fuel of vegetable origin - sawdust, straw, finely chopped branches, etc. The efficiency of long-term units, or, as they are also called, surface combustion reaches 85% - one of the highest rates among solid fuel appliances.

Long burning furnace uses the most advanced solid fuel combustion methods

Heating units in development

In terms of manufacturing complexity, a heater for working on used engine oil approaches designs using pyrolysis. By the way, the processes of pyrolytic transformation of liquid fuel with the production of combustible gaseous components also take place inside such a furnace. From a gas cylinder, you can build a universal potbelly stove with a drip supply of liquid fuel to the combustion zone (in the absence of mining, it can be heated with firewood) or a unit with a flame bowl. The advantage of mining furnaces is high efficiency, the ability to operate on cheap fuel and the absence of harmful components in the exhaust gases.

The flame bowl unit can be used in residential areas

Rocket oven

Despite the simplicity of rocket furnaces, their design uses two principles of fuel combustion at once, borrowed from long-burning units:

afterburning of wood gases released with a lack of oxygen (pyrolysis);
flow of gases through the channels of the heating device independent of natural draft.

The rocket stove can be both stationary and portable.

In a rocket furnace, the cylinder plays the role of the outer casing of the secondary chamber. Other elements are made of refractory bricks, clay, cement mortar, etc. Being one of the most complex structures, the rocket oven nevertheless remains very popular with do-it-yourselfers. The reason lies in the economy, convenience and efficiency of about 85%.

Reactive units and other mobile structures

The design of any jet heater is the simplest direct-burning rocket stove. Most often, such units are made from a piece of large-diameter pipe, which simultaneously acts as a furnace and a chimney. The draft in a jet potbelly stove is provided by a vacuum at its hot end, which is often also used for cooking. The efficiency of such a design cannot be compared with units using pyrolysis, but with regard to simplicity and compactness, jet heaters have no equal here.

Fuel consumption in a portable rocket stove is small, so even dry branches, splinter or grass tufts can be used

It should be noted that for the manufacture of this type of furnace, cylinders with a reduced diameter are suitable for storing oxygen, carbon dioxide and methane.

The design of the furnace and the principle of its operation

On the Web, you can find many options for cylinder stoves that are used for heating residential and non-residential premises. Most often they are stationary structures used exclusively for heating. Today we will talk about a unique design that, despite its simplicity, will allow not only to get heat, but also to cook liquid food, bake, and heat tea. Among other things, the oven has such a compact size that it can not only be moved from place to place, but also taken with you when outing into nature.

A portable oven can be used not only for heating, but also for cooking

Like other solid fuel combustion units, our furnace has:

firebox;
grate;
blew;
loading door;
chimney.

A feature of the potbelly stove from a gas cylinder is the combination of the combustion chamber with the furnace body. In addition to this, the design in question is equipped with a hob and a hood for baking pizza or flat cakes.

The furnace works on the principle of direct combustion. After lighting the firewood, the flame maintains a free flow of oxygen through the grate. The intensity of the fire is adjusted by moving the blower valve. The combustion products are removed through the chimney. To prevent heat leakage during the idle heater, the chimney is equipped with a rotary damper.

Necessary materials and tools

To build a portable heating and cooking stove you will need:

cylinder for household gas with a volume of 50 liters;
pipe with a diameter of 100 mm or more;
metal door hinges - 2 pcs.;
cast-iron grate;
steel bar with a diameter of 8–10 mm;
a piece of a metal corner with a shelf of 20–25 mm;
sheet steel 5–6 mm thick;
heat-insulated handles;
heat resistant primer and paint.

In order to make it more convenient to monitor the temperature during baking, use any suitable thermometer. You can fix it with cold welding.

You can’t do without a welding machine in the manufacture of a metal furnace

Everyone has the tools they need to get the job done. If from the list below you do not have one or another device, then it is better to purchase it in advance. This will save you a lot of time and nerves later on. So, here's what you need to build a mobile furnace from a cylinder:

a simple welding transformer or a semiconductor inverter designed to work with electrodes with a diameter of 3–4 mm;
angle grinder (angle grinder), or, in a popular way, "grinder", designed to work with discs of at least 180 mm;
circles for angle grinders - several cutting and one cleaning (required for working on metal);
electric drill with a set of drills;
nozzle "ring saw" for an angle grinder;
welding electrodes;
a hammer;
chisel;
tape measure and metal ruler;
scriber for marking on metal.

Cutting a cylinder with a grinder presents certain difficulties, so if you have access to gas-cutting equipment, then by all means take advantage of this opportunity.

Preparatory work

Before proceeding with the construction of the furnace, it is necessary to carefully plan all stages of work. In particular, it is required to prepare a gas cylinder and choose a place to install a heater. As for the technology, with the help of the step-by-step instructions below, it will be possible to avoid mistakes and carry out the installation as soon as possible.

How to free the cylinder from gas residues

It is impossible to start cutting a propane or methane cylinder without preparation, since even a small amount of gas, condensate or its vapors in combination with atmospheric oxygen is an explosive mixture. In order for an explosion to occur, the slightest spark is enough. You can make the container completely safe using the method below.

Turning off the valve, release the gas from the vessel.
Using an adjustable wrench or gas wrench, dismantle the faucet.
Turn the bottle upside down and drain the remaining gasoline.
Having placed the container vertically, fill it with water through the upper opening. In this case, all combustible components will be displaced by the liquid.
After drying the cylinder in the open air, you can start any plumbing work, including welding and burning old paint with a blowtorch.

Like any other saturated hydrocarbon, propane and methane are odorless. To detect a leak, strong-smelling organosulfur compounds are added to it, so all work on cleaning the cylinder is best done in open space.

What is the right place to install the stove

Despite the fact that we are considering a mobile structure, most of the time it will be used to heat a garage, shed or workshop. So that the operation of the heater does not lead to unpleasant consequences, when choosing a place, they are guided by the current provisions of SNiP, sanitary and fire safety standards.

The floor under the stove is equipped with non-combustible materials - fireclay bricks, cement-sand screed, asbestos fiber board or metal sheet.
It is forbidden to install heaters near places where fuels, lubricants and other flammable materials and substances are stored.
When installing the stove, the configuration of the chimney must be taken into account. The places of its passage through the roof must be protected by heat-insulating non-combustible materials.
It is forbidden to install furnaces of this type under shelves, in places close to attachments, etc.
It is necessary to consider how air will flow into the room. It should not be forgotten that open flame ovens consume a lot of oxygen.
When the body of the heater is located close to the combustible surfaces of the walls of the room, the latter are protected by heat-insulating shields.

When choosing the installation location of the furnace, the configuration of the chimney must be taken into account. Since most of the heat in direct combustion furnaces is thrown into the pipe, they try to place it indoors, equipping it with a long horizontal or inclined section. It is only important not to be too smart with its length and number of turns, since the traction force, and hence the thermal power of the heater, depends on this.

Instructions for the manufacture of a portable heating and cooking device

For the construction of a mobile heating and cooking unit, any 50-liter domestic gas cylinder is suitable, but it is best to take a vessel with a valve guard. Its upper part will serve as a support, so it will be possible to do without arranging legs or a supporting structure.

It is necessary to draw a line around the circumference of the cylinder at a distance of 50–60 cm from the valve insertion point. To do this, you can use masking tape or glued sheets of paper - in this case, the cut line will be perfectly even. After that, using a grinder, the vessel is cut into two halves.
The aesthetics of the entire structure depends on the accuracy of the markup.
The rim is dismantled from the bottom, after which the bottom of the container is cut off along a line that runs just above the weld. This work must be done as carefully as possible - the cut off part will be needed as a cap when baking pizza and baking other products.
One part of the cylinder will serve as a body, and the other will go to the manufacture of furnace parts.
In the body of the furnace, an opening is made for the furnace. To make it neat, use hole saws-nozzles to the "grinder". First, round holes are made at the corners of the furnace window, after which the remaining metal is cut through with an angle grinder. The downside of aesthetics is the inability to use the cut-off part to make a door. However, when using a large cylinder, the remaining metal will be enough for all the details of the structure.
The aesthetics of the opening will provide rounded corners
A door is cut out of the remaining cylindrical part of the vessel. Its size should be 10–20 mm larger than the opening - in this case, it will be possible to achieve acceptable tightness of the furnace part.
The door should cover the furnace window with a small margin
The door is adjusted to the firebox to ensure its tightest fit, after which it is attached to the body with metal hinges.
Fuel will be poured into the door located in the body of the gas cylinder
To prevent spontaneous opening of the loading hatch, it is equipped with a deadbolt of the simplest design.
The simplest valve can be equipped with a heat-insulated handle made of any material
A blower hole is cut in the bottom of the furnace, which is equipped with a valve to adjust the air supply. To do this, pieces of a metal corner are welded on the sides of the opening, and the damper itself is made from the rest of the cylinder or a suitable piece of sheet metal 4–6 mm thick. The guides are adjusted in place, after which they are mounted with an intermittent seam.
The installation of the blower damper must ensure its free movement along the guides.

To ensure a snug fit of the valve to the blower window, the shelves of the guide corners are cut to a height of 6–8 mm.
A handle and a roller are welded to the damper, which limits its movement to a certain position.
A grate is mounted from the inside of the furnace. Since it is impossible to cook cast iron with conventional electrodes, segments of a steel bar are used for fixing.
To make the installation of grates convenient, you can pre-burn a hole with a cutter and insert rods

You can do without cast-iron grates if, instead of a blower opening, a series of holes Ø10-12 mm or slots 8 mm wide are made in the bottom of the furnace.
A circle equal to the diameter of the cylinder is cut out of the middle part of the workpiece or sheet metal 4–6 mm thick - it will serve as the arch of the furnace and, in combination, a brazier. It is quite difficult to do such work with a grinder, so it is better to use a gas cutter or a plasma cutter here. If such equipment could not be found, then a polygon is cut out with an angle grinder, after which it is processed on an emery wheel.
The brazier must be welded to the top of the body with a continuous seam. Its tightness is especially important if the oven is to be used for baking.
To ensure the mobility of the structure, the chimney is made removable. To do this, a so-called collar is cut into the arch of the heater, the diameter of which will ensure a tight connection with the chimney. Such a pipe can be made from a metal strip bent into the shape of a cylinder. Often, the collar is made from the same pipe, for which a length of 10-15 cm is cut lengthwise and slightly unbent, and then welded with a continuous seam.
The size of the chimney pipe must be the same or smaller than the size of the blower door
For the manufacture of the cap, the previously cut off bottom of the cylinder is used. Since a chimney will be attached to the lid, a hole is made in it equal to the diameter of the chimney. To ensure a stable position of the parts relative to each other, the cap is equipped with exactly the same collar as the brazier.
On the back of the furnace, the cap can be attached to the body with hinges, and a latch can be equipped in the front. If you ensure its free installation, then this will allow you to regulate the temperature of the hob during operation.
For convenience, the exit under the chimney in the brazier is made from the side opposite to the loading door, and in the hood - above the furnace opening.
A hole for a thermometer is cut in the center of the cover, after which the measuring device is fixed by cold welding.
A thermometer installed in the center of the hood will allow you to monitor the degree of heating of an impromptu oven
The strips of metal remaining after cutting the cylinder can be used to make handles. To do this, they are bent in an arc, after which cuts are made from the center to the corners. So that when carrying the cylinder, the holders do not crash into the hands, their lower part is bent inward and only after that they are welded to the walls of the cylinder.
For the manufacture of handles, you can use the remaining strips of metal
To increase the supporting surface of the furnace, it is necessary to weld a previously sawn off rim to its base. All that is needed for this is a welding machine and 3-4 pieces of a thick steel sheet or bar.
The rim is installed for additional stability of the furnace

Before painting, the oven is checked in operating mode. It is important that the walls of the unit heat up to the maximum - in this case, the old enamel will completely burn out. After cooling, the surface of the heater is treated with a metal brush, after which it is primed and painted in several layers with any heat-resistant composition.

Before painting the stove, it is necessary to clean its surface of old paint in any way possible.

Features of the operation of a mobile stove

Before kindling the furnace, the blower valve is fully opened, after which scraps of paper or cardboard are placed in the furnace. Firewood is laid on top of them with a “hut” or “well”. After igniting the fuel, the furnace door should be slammed shut. As soon as a stable flame appears in the chamber, the blower damper is covered. By adjusting it, the duration of the heater’s operation is increased from one tab and the desired temperature is set. As it burns, 3-4 logs are added to the working chamber.

Any solid fuel is suitable for a cylinder stove - firewood, branches, straw, sawdust, wood pellets, coal, etc., but it is better to use hardwood - it gives more heat and burns much longer.

If pizza or tortillas will be baked in the oven, then a ceramic tray is placed on the brazier. After ignition, the firewood is allowed to burn well. Since smoke will enter the baking chamber during cooking, only hardwoods are used. It is best to prepare a supply of “noble” fruit wood from cherries, plums, apricots, pears, etc. for cooking. In this case, you will be able to get pastries with an incomparable aroma. And, on the contrary, for these purposes, you should not use pine, glued laminated timber and various waste wood building materials, since the substances released during their combustion can be hazardous to health.

There is nothing tastier than pizza baked “with smoke” in a self-built oven

The temperature in the mobile oven can be adjusted in two ways. The first is the decrease in air flow through the blower described above. The second is a change in heating, carried out by turning the furnace hood relative to the opening for the release of combustible gases. The closer the chimney is to it, the more heat will go into the chimney. Heating is controlled by a thermometer. For baking, a temperature of 200 to 260 degrees will be enough.

In order to provide the unit with normal draft and at the same time not lose mobility, the chimney can be made composite using several sections up to 1 m long.

The simplicity and accessibility of the design described above allows you to build a furnace with your own hands, spending one day on it. Such a unit is well suited for heating utility rooms and simultaneous cooking. Be sure to take the opportunity to make such an oven. It will be enough to take her to nature once and cook meat or pizza “with smoke” for friends in order to secure the glory of a skilled owner and an unsurpassed culinary specialist for many years.

But this decision seemed painfully unbudgetary to me. I really wanted a stove...
In general, hail to health!)

It all started with the fact that on the May holidays I got to the birthday party of my college friend. It was celebrated according to tradition in the country. The main treat, in addition to barbecue, was pilaf cooked on fire. I think many people are well aware of the difference between the taste of pilaf from the fire and from the stove. I have always had a cauldron. And there was no stove for it ... I decided that this is a very necessary thing in the household. In principle, it was possible to buy a ready-made stove. But firstly, I didn’t like 1 mm thick iron in standard products, which would burn out within a couple of years. Secondly, the price in the region of 5000 r for such guano seemed excessive. In the third, hurt pride, the presence of hands and tools unequivocally pushed for creativity.
To begin with, on the basis of receiving ferrous metal, an old gas cylinder of 50 liters was bought for 500 r. In household goods, small door hinges were purchased in the amount of 4 pieces for 120 rubles and a small grate was also purchased for 120 rubles. There is always a consumable in the form of strip scraps, discs for grinders and welding electrodes.

The most interesting thing was to open the balloon and not go to the forefathers. To do this, the tap was turned off with a gas key and water was poured into the cylinder in a thin stream. Now you can cut. From the beginning, the upper part is cut off. We don't throw it away. Perhaps it will go to some kind of steampunk-type product - a planter, an urn, etc. Then the marked doors are cut out. But not to the end. We weld the loops. And then we cut the doors.

The grate is rectangular and the balloon is round. We overlap the excess section with sectors cut from the strip. They also serve as a support for the grate.

Doors must have handles and the top must be securely locked.

A cauldron for 8 liters fits perfectly. On the right you can see a 110 mm outlet for welding. Since the smoke gases need to go away, preferably not in the face of the cook, he will be crashed from behind. At the same time, small decorative elements are waiting for the stove, already purely for design and painting with heat-resistant enamel. And side handles for easy cleaning.
