Crafts from wheel rims. DIY barbecue made from car rims
Car rims not only hold the tires and allow the car to move, but are also part of its appearance, so very high demands are placed on them. In case of the slightest deviation, the disks are replaced, because the cost of a new part cannot be compared with the costs you will go through to eliminate the consequences of an accident due to a defective disk. Next, we will tell you how you can give a second life to these car parts and what can be made from them.
Disc processing
There are discs various types, however the most popular are:
- stamped and forged steel;
- light alloy cast and forged;
- titanium cast and forged.
The former can be cut without any problems with an autogen or plasma cutter, welded with an inverter and cleaned with a sandblaster. The latter can be cut and cleaned by any means, but for welding you will have to use a semi-automatic machine with an argon cylinder. The third type of disc can be easily cleaned with a sandblasting machine, but cutting it with any tools is not easy due to the high strength of the metal. To weld, you need a special inverter that produces a direct current of sufficient magnitude and cylinders with argon or helium.
A sandblasting gun with air compressor and sifted sand. You should not clean the metal surface with solvents, because they cannot even completely remove paint, leaving oil traces and, moreover, they will not cope with rust. Another advantage of the sandblasting machine is that after processing it, the surface of the disc becomes perfectly clean and does not require degreasing before painting. When working with sandblasting, be sure to wear protective equipment, including goggles and a respirator.
Any powerful inverter capable of working with 5 mm electrodes and delivering up to 200 amperes of operating current is suitable for welding steel disks. However, many use electrodes with a diameter of 2–3 mm and a much lower current, because the weld is not subject to maximum loads.
What can be done
Here short list what can be made from old rims:
- sink;
- bar stool;
- flowerpot;
- bake;
- barbecue grill;
- hose reel;
- coffee table.
Light alloy wheels are best suited for creating a shell, but stamped ones can also be used. To make a sink, clean the metal of paint and rust, then weld all the holes except the center one on the outside. For maximum effect Weld the patches so that they form a smooth surface with the inside of the entire part. Then, first with a grinder, then by hand, clean and polish the inside of the disc to a mirror shine. Insert the sink blank into the cabinet prepared for it and install the siphon. The faucet can be installed either in place of the nipple or on the cabinet, whichever you prefer. It is advisable to cover a steel sink powder paint or electroplate it with any protective metal, such as zinc.
Bar stool
There are many ways to make a bar stool, but any of them will require at least three sandblasted rims. In addition, you will need a round seat from a real bar stool, which you can either buy or make yourself.
To make a flowerpot, just turn the wheel rim, cleaned of paint and rust, face down, place it on the ground and fill it with soil. If you are not satisfied with its natural color and want to protect the metal from rust (only relevant for stamping), then coat it with powder or any other paint suitable for metal and outdoor work.
For this, it is advisable to use forged or stamped steel wheels, because light alloy wheels are afraid of strong heat, and titanium wheels can be used in more worthy ways. To make a stove, you need to place two steel disks on top of each other, turning them towards each other internal parties and boil at the joint, then cut a hole for storing firewood. The finished stove will need to be placed on bricks or stones so that air can pass between its lower edge and the ground without problems. If several holes are cut in the outer sides of both disks, then the stove can be placed directly on the ground, and a pot or frying pan can be placed directly on it.
To make a barbecue you will need a cleaned disk and a corresponding shaped grid made of steel rod with a diameter of 7–10 mm. Weld legs of a suitable length to the outer part of the disk to make it more convenient to work with the barbecue, and weld the simplest loops for the grate to the inner part; they can be made from a rod and a tube.
To make a table you need a cast or forged light alloy wheel with a beautiful spoke pattern and round glass with a thickness of 10 mm or more. Place the disc face up on the table using special glue. If you only have regular superglue, then place the glass on the disk and use a marker to trace its outline along the outside of the glass. Then degrease the contact points on the metal and back side glass with any alcohol-containing liquid.
After the alcohol has dried, quickly apply glue to the metal surface in the contact area and on the back of the glass, both adhesive layers should be 2-3 mm wide and completely symmetrical. Immediately lightly sprinkle glue on the glass baking soda and place the glass in place, pressing it lightly. Since you will only have one attempt, we recommend that you carefully practice this operation before applying the glue. Lastly, remove traces of marker from outside glass
Made barbecue, oven, barbecue. a smokehouse made from car disks is an example of how waste materials can be reused for useful and desired design. These wheel rims are quite simple to make; you can make them yourself in the garage or in a home workshop. Although the design is simple, this product can be used for many tasks.
How to make a grill from rims
For self-assembly For this design of car disks, we think in advance what the layout of our product will be. We prepare consumables in the right quantity, as well as a list of tools. To do a quality job, you need to be able to use a grinder to cut metal and a welding machine.
A simple option - a grill for skewers
More complex grill models with grill grates
How does a barbecue oven work:
Below we put firewood or cooked coals. A grill is placed on top or skewers are placed. We can also place the dishes on the wire rack or directly on the wheel, if the size is suitable. Thanks to the heat that rises, you can cook food in the same way as a regular barbecue. If we want to smoke food, then we close the exit at the top, make sure that the wood chips smolder - smoke should form. In each case, an individual design is thought out, depending on the needs of the owners. However, when assembling the device, the basic design principle is the same, regardless of the model.
Smoking chamber made from car wheels
A barbecue made from disks will be more profitable if it is adapted for various tasks. For those who prefer homemade balyk and sausages, we recommend a smokehouse, which will serve as a device made of disks. Such a useful thing is made using at least two units of material.
The work is based on the principle in which two disks are connected to form a solid hollow structure. Top part is modified to make it convenient to fry kebabs - as in the previous model. However, in order to preserve the smoke, a lid and a smoke exhaust system should be installed. The partition with holes can be left, which will be easier. In this case, the device can act as a hob.
To secure the door, we weld a nut onto it so that they are symmetrical with respect to the weld seam. One bolt at a time is also fixed to the grill by welding in such a way that the door nuts are placed on them. After this, the grill is ready! Now you can enjoy the cooking process and the dishes themselves.

A design like a barbecue made from car rims is great option reuse of waste materials. Such a device is simple to implement, and therefore you can make it yourself. Despite the simplest design, there are enough ways to use the product, it can even replace a comprehensive barbecue model.
Design Features
A self-made brazier from a wheel disk has a mass positive characteristics. This design allows you to get a full-fledged grill complex with minimal costs for its production. All materials are quite accessible to almost any summer resident. In addition, they guarantee the durability of the product and its strength under any operating conditions. Another plus is the compactness of the grill. About him distinctive features and execution options are worth discussing in more detail.

Materials used
In order to make a barbecue from disks, you will not need to spend a lot of money, since practically available materials are used for its production. Car wheels that have already used up their useful life are usually thrown away or sold for scrap for pennies. This does not take into account the many ways to use them alternatively, among which making a barbecue is one of the best options.
For a dacha or private home, a barbecue is considered a mandatory attribute. Manufacturing from old disks allows you to save money, since ready-made models in terms of their capabilities in relation to cost, they are often inferior to this option.
The onset of the cold season leads to the need for heating or simply creating comfortable microclimate parameters in garages or auxiliary buildings when living outside the city. This problem becomes especially urgent in conditions of impossibility of centralized heating.
Please note: almost every motorist has at least one unnecessary old wheel. Otherwise find suitable material You can buy it from friends, neighbors in the garage, or buy it for a small amount at a service station or from your own hands.
The advantage of using discs to create a grill is the thickness of the metal. Even worn wheels will be suitable for this type of further use. The metal does not fade or deform, and their shape is ideal for creating complex products for cooking on coals.
Principle of operation
The operating principle of a barbecue made from wheel rims is similar to some other homemade models, for example, those made from a barrel or a cylinder. It combines the following features:
- grill - allows you to cook on skewers or a removable grill;
- barbecue - for frying steaks, complemented by a lid that creates the effect of an oven;
- hob - the shape and diameter of the disk allows you to place a cauldron, frying pan or saucepan on the fire;
- smokehouse - some models allow you to hot smoke food.
The principle of operation is extremely simple. Firewood or finished coals are loaded into the lower part. A grate is installed on top or skewers are placed. The dishes can also be placed on the wire rack or directly on the wheel, if their diameter is compatible. The heat from below warms the air and allows you to cook as on a regular grill. To smoke, you need to close the top exit and allow the wood chips to smolder to create smoke.
Each design is thought out individually, tailored to the needs of the owners. However, the main part of the work on manufacturing the product remains common to all models.
Execution options
Need to consider in more detail possible options product execution. If you want to make a grill from car rims, you need to pay attention to the following models:
- Simple grill. The wheel is a container for coals on which skewers or a grate are placed (We recommend studying the material on our website).
The simplest option is a grill for skewers
- Double design. 2 wheels are used, thanks to which the grill becomes higher. Due to this, you can put a cauldron on top. Heating from all sides allows you to cook in it delicious dishes like in the oven or stewing them.
- Closed oven. Allows you to smoke food, as the smoke collects inside the chamber and is released in small quantities through special openings.
- Complex models. It combines all 4 functions of the product described earlier. Additionally, other useful elements can be installed, for example, a chimney exhaust.
It is also worth noting that such a grill can be made with or without legs. A stand will be needed for single models, but in double and triple models its function is performed by the lower disk. However, there are restrictions regarding the use of the design, because wet ground may interfere with the formation of heat, and hot metal is not allowed to come into contact with the wooden floor on the deck.
Making a barbecue from disks yourself
In order to make your own grill from car disks, you need to think in advance about the design of the future product. Decide on quantity Supplies, prepare your tools. To perform high-quality work, you must have the skills to use a grinder for cutting metal, as well as a welding machine.
Preparation of materials and necessary tools
In order to make a barbecue from rims with your own hands, you will need the following materials and tools:
- old car wheels;
- Bulgarian;
- nozzle for cutting metal;
- disc for removing rust in the form of an iron brush;
- file;
- drill;
- hammer;
- bolts;
- profiled pipes or steel rod;
- grill grate.
Bulgarian and welding machine- the main tools when working with metal
All these tools will be needed to process and connect the parts of the grill. It is convenient to make legs from profiled pipes and rods. In total you will need 3-4 of them.
Tip: it is better to make 4 supports for greater stability of the product. The tripod may fall to one side when placed on an uneven surface.
You need to prepare the wheels themselves in advance. If there are traces of rust and paint, the surface is cleaned wire brush using a grinder or drill. All excess is cut off.
Simple option
Several options for manufacturing such grill structures should be considered. You need to start with the simplest thing - a single barbecue made from a wheel disk on legs. In order to do it, you will initially need to carry out a number of manipulations with the disk itself:
- One side is cut out inner part- partition. A container similar to a cauldron is formed.
- If there are too many holes in the bottom or they are large enough for coals to spill through them, you need to weld an additional plate. You should not completely close the gaps, since the coals must be blown out to maintain heat.
- Legs are welded on the sides to the bottom or closer to the top. Usually they are made 40-45 cm in length. This height of the barbecue is optimal, as it ensures the stability of the structure and ease of use.
Next, if necessary, you need to clean the cuts so that there are no sharp edges left. You can additionally install a grille. It is not necessary to weld it; it is more profitable to use removable parts. Also, for the convenience of maintaining heat and cleaning out ashes, you can make a window for firewood on the side of the disk. For transfer, the structure is equipped with handles, welding them symmetrically on the sides of the wheel.
Tip: if you use two or three wheels, you can limit yourself to welding metal bars to the bottom. In some cases, you can do without supports altogether.
Smoking chamber
It is more profitable to make a brazier from car rims that can be used in different directions. For lovers of homemade balyk and sausages, a smokehouse will be an indispensable device. In order to turn old wheels into such a useful thing, you need to use at least two units of material.
The principle of operation is that you need to connect two disks into a solid hollow structure. The top can be adapted for frying kebabs according to the principle of the previous model, but to preserve the smoke you need to take care of the arrangement of the lid and smoke exhaust system. You can leave the partition with holes, which will simplify the task, and use the product as a hob.
Structural and functional features grill-steam locomotive, cost of the product, selection of materials for self-made, construction installation technology.
In order to combine two disks, it is necessary to cut off the partitions. Next, the wheels are joined and welded with a continuous seam to each other. The legs are welded to the bottom of the lower element. A door is equipped to provide access inside. To make it, you need to go through the grinder approximately in the middle of the product and cut out a rectangle.
To secure the door, one nut at a time is welded to it, symmetrically with respect to the welding seam. One bolt is also attached to the barbecue by welding so that the door nuts can be put on them.
Tip: to secure the sash without any problems, first screw the bolts into the already welded nuts. Then the door is applied to the opening and fixed on the structure itself.
Such homemade barbecues allow you to create all the conditions for relaxing with barbecue with minimal costs for equipment. In addition, there is no need to apply any extra effort, because all stages of the work are extremely clear and easy to implement.

A stove made from car wheel disks can heat a room up to 15-16 square meters. m, heating a bathhouse or becoming an inexpensive, effective cooking device, which is what this article is actually about. Its main advantage is the availability of high-quality material - thick, resistant and durable steel. Boiler steel in sheets and profiles is expensive, and ordinary structural steel in a furnace structure quickly burns out.
The additional advantage of a disk oven can be seen through experience. Take two pieces of metal of approximately the same size and weight: one from simple steel, and the other cut from a wheel rim, and heat it up stronger, at least in the kitchen on gas. The first one will immediately give off the smell of hot iron, and the second one can be heated to orange (about 900 degrees), without feeling anything unpleasant in the air. A furnace made from wheel rims practically does not dry out the air and does not emit harmful fumes into the atmosphere, because the rims for the wheels are made of special steels that are resistant to corrosion. Of course, they are not standardized for heat resistance, but The reserve of resistance that is built into them is quite enough for a wood-coal stove.
What you need to know about disks
The furnace is being worked out. made using car wheels. Don't do things like that!
To make a furnace from disks with your own hands, you need to know not only the advantages, but also the disadvantages of the source material and some, significant in this case, features of the design of furnaces. The disadvantage of special steel is that it is not standardized for welding properties. There are several technologies for the production of wheel rims, but if welding is used for this, it is very limited, followed by thermal tempering (annealing) and flaw detection of the seam. And, of course, no vehicle designer expects anything to be welded to the wheels during operation.
This leads to a very important conclusion from a safety point of view: from disks (see figure), as well as pyrolysis ones, This should not be done under any circumstances! Unless you really want that at one not at all wonderful moment boiling, most likely burning, oil will flow through a crack in the seam or chemically aggressive, highly toxic gases will begin to be released. But these stoves cannot be extinguished; they must burn out completely. Disks can only be used to make a solid fuel combustion furnace.
Note: welding seams For special conditions Operations that are not properly quality controlled are considered unreliable. Welded vessels operating under pressure, heat and for chemically aggressive contents that have not undergone flaw detection and subsequently tested in the operating mode of use are a priori recognized as unsuitable. Any oven satisfies at least two of these conditions.
However, it is possible to make a completely safe solid fuel stove from car rims by welding for non-residential premises (country house also applies to them) is quite possible if you follow the following. rules:
- The weld must be of visually high quality, without visible defects - cracks, splashes, holes, bubbles, see fig. on right;
- You can only weld two mating parts at a time; under no circumstances should you weld the entire structure at once!
- After making each seam, the welded parts must be given a rest to allow residual internal stresses to resolve, approx. from 3 minutes per kilogram of mass of connected parts. In practice, cook further no earlier than when you can touch the metal with your bare hand 3-4 cm from the end of the seam;
- The finished furnace, after being left for a day to absorb the same stresses, is subjected to a test run, from 3 hours for a stationary one and from an hour for a portable outdoor one, at full power, i.e. with the air throttle (if equipped) or combustion/blower door fully open, and maximum fuel load.
During the test run, the furnace is annealed simultaneously. Discovered minor defects welds, no more than 2 per seam, are eliminated after a day, after which the furnace run with annealing is repeated.
Note: The modulus of the coefficient of thermal expansion of TKR steel for car wheels is significantly less than that of structural steels. It’s clear why, but this circumstance also needs to be kept in mind when making a stove, see below.
What you need to know about ovens
When making a stove from car rims, you need to be aware of one more circumstance. According to the rules for the construction of combustion furnaces using solid fuel from the firebox or grate, i.e. from where the fuel is placed to the first vertical obstacle to the current flue gases(for example, the roof of the firebox) should be at least 40-50 cm if standard fuel is loaded into the stove. If it is damp or waste, the specified distance should be increased to 60-80 cm; The heating time of the oven will then increase. The latter is unimportant for disk furnaces, because they warm up quickly.
The reason is from solid fuel hot pyrolysis gases are released, contributing a significant, or even decisive, share to the heat release. If pyrolysis gases come into contact with a less heated surface, they will not be able to burn out and soot will fall out. With further use of such a stove, it will become coked - dense carbon deposits will form on the roof of the firebox and in the chimney. It not only reduces the thermal efficiency of the furnace (analogous to efficiency in furnace business), but also a fire hazard.
Note: a high firebox for raw fuel is made so that the pyrolysis gases and water vapor have time to separate, and the former also burn out before reaching the roof. In this case, fuel is loaded to no more than half the height of the firebox.
Disk stoves are very often operated using waste fuel (rotten dried wood, damp scraps, etc.), but at the same time, there may simply not be enough unusable disks for a high stove, or the optimal stove design in this case (see below) ) will not allow you to make a high firebox. Then you can make a furnace from disks by using a non-standard grate made of steel sheet from 6 mm and reinforcing rods from 10 mm. There is no need to fear that there will not be enough air for combustion: through a hole with a diameter of 10 cm, with a chimney 1.5 m high, it will pass enough for a power of 18 kW for wood and 30 kW for coal. A furnace made of disks will never develop something like this.
The non-standard grate is simply inserted into the oven with a gap of approx. 6-10 mm, due to the difference in TKR materials, see above. This design has another advantage - it solves the problem of the ash pan, which is quite serious for disk furnaces. In this case, they simply substitute it under the ashes tin can with a diameter of 15 cm.
Note: horizontal furnaces made of disks (see below) are made without grate for the same purpose, i.e. the fuel burns on the stove floor, and the air flow is regulated by a throttle in the ash pan. The durability of steel for discs makes it possible to use such a solution.
What kind of oven should I make?
Based on the above, the possibilities of making a stove yourself from car disks can be sorted out like this:
- When it is desirable and necessary, because the use of auto disks allows you to improve the quality of the stove and/or simplify its manufacture.
- When possible, for the main (fire) parts of the furnace structure instead of expensive heat-resistant steel.
- When possible, partially as a sufficiently resistant material at hand.
- When you can’t do anything - discussed above.
When needed
The best use of oven disks is in mobile (portable) street and garden cooking stoves and as a firelight. In the simplest disk-based stove for a summer residence, a large mass and height of the side (rim of the disk) are used, which allows stabilizing heat transfer and provides some protection from the wind. How to make a simple country garden stove from car disk, see video:
Video: mini garden oven made from car rims
For the cauldron
However best use car disks in garden stoves- under the cauldron. The oven made from disks for a cauldron is completely round, namely in the corners brick oven Under the cauldron, the cooking utensil heats up less, and soot settles there. The disk stove ensures absolutely uniform heating of the cauldron and saves firewood, which is very significant when using waste fuel. The branches and chips collected on the site and in the surrounding area may not be enough for the pilaf or beshbarmak to ripen as expected. And damp and rotten fuel in a massive brick firebox simply will not heat the cooking vessel to the required degree. In a cauldron oven, both are excluded from auto disks, but – let us emphasize – if it's done correctly.
Flue gases follow the path of least resistance. If you simply weld 2 disks and cut a combustion hole on the side, then hot gases will flow through the technological (to facilitate the design) holes in the disk hub, pos. 1 in Fig., because their total area more than fastening and axial ones, and they are lower. If the stove is heated to maximum, then perhaps a tongue of flame will appear from the axial hole, pos. 2, but with a cauldron on the burner of such a stove, all the heat will again go to the side to no avail, pos. 3, or, if you try to plug some of the technical holes, or add fuel, the flame will burst out of the loading door, pos. 4. On such a stove, food prepared by simmering over coals turns out well, pos. 5, but not everyone cooks this way.
A proper stove for a cauldron made from disks must, firstly, be equipped with a tightly closing door on the loading opening. Secondly, the cauldron should sit in the cutout of the burner, partially blocking the technological holes in the hub, pos. 6. This is not difficult to achieve: you need to cut out the middle of the hub with a grinder, as shown in pos. 7. The remainder will not go to waste - it will make an excellent grate. How to make a garden stove for a cauldron from car wheel rims, see also video
Video: oven for a cauldron made of disks
BBQ option
It is not necessary to cut out the core of the disk hub, except for simmering on coals, in the case when a garden barbecue oven is made from disks. Then a grille is placed on the burner - a flame divider, which will at the same time serve as a culinary grille-rasper. The advantage of this design is that several different temperature zones are formed on the rasp, pos. 1 in Fig. on the right, which allows, for example, to simultaneously cook rare roast beef (half-raw with blood), medium (juicy, moderately baked, like a shish kebab), and well done (fried until crispy). If there is a group of people at the picnic, everyone will get something to their liking at the same time. It is advisable to make such a furnace from disks with a small number of wide technological holes in the hub, for example. from Gazelle. The grille is made from bicycle spokes. There is no need to cook them: they are perfectly joined with heat-resistant metal glue (cold welding).
Note: sometimes stoves without a combustion door are made from disks of the same type (item 2 in the figure on the right), placing thin wood chips through the technical holes in the hub during combustion. But the stove turns out to be gluttonous and does not cook well. Why - see above.
When you can completely
A heating stove-potbelly stove made entirely of disks works well. The advantage in this case will be its large heat capacity and heat transfer time - the metal of the body is thick - although, of course, not the same as that of cast iron, and some increase in efficiency. The downside is the higher labor intensity of manufacturing improved furnaces with increased efficiency due to the complex configuration of the housing.
If there is plenty of waste fuel, then a stove-stove made from disks for heating small room can be made without internal partitions-dividers (see below) horizontal, pos. 1 in Fig. It is highly advisable to make such a furnace from disks truck: firstly, a larger furnace volume will increase its efficiency and heat transfer time. Secondly, due to the complex surface of the disk rim, the area of the outer surface generating heat can be one and a half to two times larger than that of a simple round one of the same volume from a barrel or. The same circumstance, together with the high corrosion resistance of car wheel rims, makes it possible to equip the stove with a jacket for water heating, see for example. track. plot:
Video: potbelly stove made of discs with a jacket
Horizontal potbelly stoves are bulky, so vertical ones are often made. If we are talking about a stove made of disks, then, firstly, you need to take care of a suitable grate and ash pan for it, see above. You can’t let coals and hot ash fall directly onto the fire protection area!
As for thermal properties, they can be improved in two ways. The first is when quick heating of the room is required, and the heat transfer time is not significant, for example, if the stove is placed in a garage. Then its upper, hot part is surrounded by an annular casing made of thin steel (not galvanized! Zinc melts at 440 degrees, and its vapors are poisonous!), with a gap of 40-60 mm, pos. 2 in Fig. The potbelly stove thus turns into a heater stove. But, by the way, a horizontal furnace-heater made of disks will be much more efficient, see below.
The second method is used when, on the contrary, it is necessary to increase the heat transfer time after combustion, for example, in country house, inhabited from spring to autumn. To do this, you need to line the stove with any in an accessible way materials that combine high heat capacity and thermal conductivity. The stove stone soapstone (soapstone) is expensive, but fireclay brick(item 3) will completely replace it. As a last resort, you can put a heavier and denser wild stone on the hob, pos. 4. If the stove consists of 4 weight disks, the fuel burns out completely and the view closes by midnight, then in a tracksuit under an army blanket you sleep peacefully until 6-7 o’clock in the morning. You can get some sleep.
Let's improve the potbelly stove made of disks
It is possible to increase the thermal efficiency of any potbelly stove by installing cut-off partitions inside. This creates an afterburner chamber. In this case, the air casing, which converts the stove into a heater, also increases the efficiency of the stove.
Diagrams for constructing potbelly stoves made from disks are shown in Fig. The simple vertical one (item 1) is more compact, somewhat more efficient than the horizontal one (item 3) and provides a cooking surface, but installing an afterburner chamber cut-off device (item 2) in it is more difficult, because in this case, it must be welded to it along the entire contour adjacent to the furnace body. However, a vertical potbelly stove with a single-turn afterburner achieves an efficiency of slightly more than 60%. A simple horizontal potbelly stove (item 3) is the worst in all respects, but quite effective stoves are made on its basis. The leading value for developing modifications is the smallest inner diameter fuel chamber d.
Note: To weld the body of a potbelly stove from car wheels, their hubs are completely cut out, see fig. on right.
Dimensional ratios for potbelly stoves made of disks with a single- and 2-turn afterburner are given in pos. 4 and 5. The efficiency of both is approx. 60%, but the 2-turn keeps it on junk fuel, and the single-turn requires quality to ensure the highest possible thermal efficiency. Cut the cutter (steel from 4 mm) exactly according to inner contour there is no need for a furnace body: you only need to select holes in its blank so that there is a gap between the cutter and the body wall of approx. 1.5 cm pos. 4a. Then the afterburner will become self-adjusting to the progress (firing mode) of the furnace and it will maintain efficiency close to maximum, both at low and at full speed ahead. A similar solution is used in Buleryan stoves, but for this purpose holes are punched in the cutter. In mass production, this is more profitable: the cutter is still cut out in one stroke of the press punch, and metallurgists willingly buy metal waste as a high-quality raw material for open-hearth furnaces. Well, at home it’s easier to leave a gap along the edges of the cutter.
A horizontal potbelly stove made of disks with an afterburner is generally comparable in efficiency to a Buleryan if it is equipped with an air casing with a slotted nozzle at the top and an air intake skirt at the bottom, pos. 5a. The casing should be adjacent to the body from the outside, and the resulting channels will act in exactly the same way as in the buleryan or stoves Engineer Butakov, Fire-Battery, etc.
Note: in the chimneys of highly efficient potbelly stoves made of disks (items 2 and 5), there must be a condensate collector with a drain valve, because the flue gases coming out of them are slightly warm.
Based on a horizontal potbelly stove, you can make a full-fledged heating boiler from disks, pos. 6. If you weld its flame body from KAMAZ disks, you can accelerate to a thermal power of approx. 40 kW, and this is enough to heat an ordinary residential building.
However, making the heat exchanger body from disks of the same size, pos. 1 in Fig., is irrational: then you will have to install a fire-tube heat receiver, pos. 2. It is better to weld the heat exchanger body from smaller disks, for example. from passenger car. The temperature in it will then rise to values that allow the use of a water-tube heat sink. Of the preventive measures, it only requires an annual pressure test in order to pressurize the system before startup and inspect it after it.
A water-tube heat receiver is a thin, solid coil through which coolant flows. The distance between the branches is equal to the outer diameter of the pipe; The branches are arranged in a checkerboard pattern. You can make a water-tube heat receiver for the heat exchanger of a home boiler from disks from copper tube with a clearance of 20 mm and a wall thickness of 2 mm. In this case, the input and output of the heat receiver into the heat exchanger is sealed by cold welding.
Oven partially made of disks
As components Autodiscs are widely used in sauna stoves. A sauna stove made of disks can be built entirely, but only for a barely average-level sauna. In a Russian bathhouse, the steam from any all-metal stove is harsh.
What a sauna stove built using car wheel rims looks like is shown in Fig. rights, and a complete diagram of its structure is given in Fig. below. The main thing that this furnace provides is proper quality pair - brick firebox. Autodiscs are used as a container for the contents of a closed heater and for the manufacture of a water heating tank.
Note: building a homemade sauna stove with an open heater is only possible with a special design entirely made of brick, ensuring complete, up to carbon dioxide and water vapor, afterburning the gases coming from the firebox before they reach the heater. Branded metal sauna stoves with an open heater they make for this from special materials using complex technology. If you try to repeat this on your own from ordinary materials, a cloud of soot will fly out of the heater with each addition of water.
This sauna stove has already been repeated by many who like to take a steam bath in their sauna. In general, everyone is happy; Only one permanent defect was noticed: the lower cutter (parts Strut and Reflector on the right in the figure) after a year or two becomes warped and comes off from the struts, or the struts from the body. The reason is obvious: different TKR steel of the specified parts and the body from the auto disk. To eliminate the defect, it is apparently necessary to make the cutter also from a smaller disk, for example, a passenger one. Most The rims must be cut out, leaving 4 legs. Then heat the transition points between the rim and the hub and bend the legs to size.
There is no need to weld holes in the hub. Due to heat transfer to the body, the shutter will be slightly cooler than the flue gases. Since the hub is convex, a gas plug forms under it, like a gas view in bell furnace, as in a bad garden stove made of disks, see above, and the flue gases will still flow around the bottom of the heater, as shown by the arrows in the diagram.
Combi option
Amateurs don’t have dozens of worthless wheel rims lying around in their garages, but wear out, as a rule, in pairs, either front or rear. In this case, in order to make a sufficiently efficient stove with a high firebox from the disks, a couple of disks will need to be supplemented with a piece steel pipe suitable diameter with walls from 6 mm.
The design of a furnace made of 2 disks from car wheels is shown in Fig. It does not differ in anything special from those described above. The same oven can be made horizontal. For the design of the burner, see above.
