Operating principle

Kuznetsov proposed a new principle of building brick furnaces. In all the previously designed/designed models, hot gases move through the channels. Passing on them, they heat the brick, cool themselves. Movement is possible only in the presence of traction. With such a forced principle of action of warming up the body is uneven, but this leads to the formation of cracks. A large number of bricks occupies almost the entire space, and the heat exchanger, if necessary, has nowhere to put. Just place it in the furnace, where he will contact with the flame, which is why his service life is very limited. In addition, the heat exchanger located in the combustion zone takes a significant part of the thermal energy, worsening fuel combustion conditions, which reduces the efficiency of the furnace and increases the number of soot.

This is how one of the internal channel furnaces appears.

Another is Kuznetsov’s use of the free principle of gases in a furnace. The stove is made up of upside-down caps by the bottom of the vessels (varying models may have a hole at the top or not). The caps can be placed next to one another or one after the other, but they must be in communication with one another via a dry seam, which is a gap of two to three centimeters that isn’t filled with a solution or heat insulator and allows gases to pass from one cap to the next.

The firebox and first cap are integrated into one area. This is what occurs when using this device. Top-ranking gases are the hottest. They stay at the top for a while, cooling themselves while transferring some of the heat energy to the walls. They fall as they cool down, to be replaced by new, hot ones. The air masses in this construction move only as a result of inherent physical processes.

The idea behind the gases in the caps

A simple way to show the procedure is to direct a stream of smoke into an upside-down glass. The cooled portion of the smoke along the walls descends as it rises and reaches the top. It’s noteworthy that the processes going through the furnace are the same, albeit far more intricate.

A diagram of the hot air in the caps is depicted in the figure with red arrows. The movement of cold air entering the oven was indicated by blue arrows. As seen in the figure on the right, it is clear that he will not rise because of his greater weight but rather descend and essentially have no effect on the cap’s overall temperature.

But one cap is not enough for effective heat selection, because most furnaces have two or three vaults depending on power. They occur in almost the same processes as in the first: more hot gases are at the top, heating the masonry, the cold passes down and go into the chimney. In the upper zone of the second arch, a heat exchanger is placed or any other device required for any purpose. No open fire, only hot gases and very effective heat: high -temperature air flows constantly flow. Moreover, the heating of the coolant, stones or water in the tank does not have any impact on the processes of combustion: they are separated from the furnace with a brick wall.

Among the possibilities for a capof a cap

The design of furnaces of different configuration and purpose is different, but they “consume” a little fuel and remain hot for a long time. This is what the reviews of the owners. For example, such an oven is composed in the house of the beam. At -25 o will be drowned in the morning and in the evening of 5 flights (in total a day it turns out about 18 kg of firewood). In the house +25 o C and in the morning is not cold. At a temperature “overboard” up to -10 o they drown once once. So there are no questions about the effectiveness. If there are questions, then by the reasons for choosing the Contractor. After all, the parameters of her work depend on how correctly and competently the stove is composed. And you can’t do it quickly: medium sizes and without bells and ground-this is 2-3 weeks of work. In general, with reviews about Kuznetsov’s furnaces, everything is simple: people are satisfied. Pleasure is certainly expensive, but it is definitely worth it. This is claimed by all owners of such furnaces. No difficulties in operation, economical and not capricious, give heat for a very long time, and they are warming up quickly.

The Kuznetsov heating hob is a dependable and effective option for improving the warmth and coziness of your living area when it comes to home heating solutions. The Kuznetsov heating hob offers an economical and environmentally responsible method of heating your home by fusing traditional craftsmanship with contemporary technology. This heating solution blends in seamlessly with any home thanks to its elegant design and simple installation process, distributing heat evenly and consistently throughout the room. The Kuznetsov heating hob is a viable and eco-friendly solution for year-round optimal thermal comfort, regardless of your motivation for lowering energy expenses or just making your house cozier.

The advantages of domed furnaces

Numerous furnaces use this concept for different reasons. Multiple caps are possible; they can be positioned horizontally close together or above one another (usually used to conserve space). They can also have symmetrical or asymmetrical structures. Ovens of any type and configuration can be designed with this feature for any type of space and set of circumstances. The characteristics are still high in this instance: Kuznetsov’s dome furnaces have efficiency levels above 80%, which are practically standard.

Any device can be installed in the second cap, including a bread furnace, heat exchanger, stove, hot water tank, and hob. Despite the numerous changes, they all share the same high level of economy, efficiency, and uniform heating. Furthermore, because of the caps’ vertical orientation, the bottom is warming more quickly than the top. Therefore, it is comfortable in a room with such a stove.

Certain Kuznetsov furnaces resemble artwork more than they do

It should be mentioned that this type of furnace requires far fewer bricks to build, meaning there is more interior empty space. The stove warms up more quickly as a result. However, as is typical, it does not cool down more quickly. Everything works "vice versa": Compared to more massive analogues with numerous channels, Kuznetsov’s dome stoves produce significantly smaller daily temperature fluctuations. And all of this is due to the fact that the coldest gases settle and are diverted from the furnace, while the hottest gases stay in the caps. Thus, the stove cools more slowly.

The oven cap has less resistance to air flow because there aren’t any narrow channels or ones that are hardly there, which results in shorter chimneys. As such, construction is simpler and, while still required, the foundation is not as large.

The stove complex was constructed using the concept of large furnaces.

Adjust the oven’s operation with free gases after determining the type of pumping and access to the operating mode. It’s a self-regulating process. The amount of hot gases increases and squeezes the colder in the second cap if the fuel is highly flared up. Additionally, air entering through blowing is what makes them colder. When there is not enough air, the flame becomes stuck, the hot gases shrink and rise both above and below as more air enters. The burning starts up again. Consequently, the valves in Kuznetsov’s two collp furnaces are primarily for non-standard modes, despite their extreme rarity.

An additional furnace complex

Any fuel can be burned almost entirely through automatic combustion process regulation. In other words, this type of stove is omnivorous and doesn’t have high fuel requirements. It reaches a normal regime when using wet fuel, but after that the process stabilizes and the soot burns out. Another benefit of domed furnaces is that they require very little cleaning because the soot burns and there is enough ash left over.

Types of Kuznetsov"s furnaces

There are numerous options because caps can be positioned in various ways, as was previously mentioned. The fact that any device’s second dome can be installed with heat transfer without compromising the combustion process also adds to the variety of thermal units. In addition, devices with any kind of combustion—upper, lower, pyrolysis, layered, etc.—can be created using this principle. While each one has some specifics, they are all achievable. On his website, Kuznetsov outlined projects with varying goals and an order. Although they are freely available for personal download, their carriage is not requested.

Fireplaces constructed using the capacious furnace principle

There are Kuznetsov furnaces for two -story houses, and they heat both levels. And there are such units with stomachs. Heating can be convection type (only from the walls of the stove) or orally water heat exchanger can be inserted. Then such an unit is called a boiler and indicated by a kick. Four finished water -heating brick boilers with a capacity of 16 kW, 17 kW, 34 kW, 64 kWs were posted in the public domain on the official website of Kuznetsov. They can be built in a tank for heating water for household needs. The boiler needs to be tied with metal corners, if necessary, you can insulate, lay a reinforcing mesh on top and plastered.

Stove heating. Gorgeous

Convection furnace options are significantly more numerous. There are twenty-five distinct projects under the heating and welding furnaces without the use of Chamotis brick OVIK section. For a heating-welding furnace with a fireplace, there are three choices. You can find the fireplace on the side, either to the right or left. These options are denoted with OVIK BC (side fireplace); OVIK BC 13l is the option that includes a stove and fireplace. with a rear fireplace situated behind the Ovik ZK marking.

Kuznetsov’s heating-welding oven appears to be highly commendable.

IOK marks heat units that are used only for heating. The letters "lying" or "l" are used in the names of guns bearing lieutenants; the letter "D" is added if an oven is present. Furnaces with fireplaces are another option available. They have OIK to attached to them. Fecal stoves PKIK1X are available. The categories for bread and greenhouses are highlighted separately.

Russian stoves made by Kuznetsov are identified by the RNI; the orderings of ten models—two of which have stomachs—are laid out. They have the standard hob configuration, with a sealed damper at the mouth. The stove will not operate as intended if the camera is not tight.

In the section of the furnaces for the bath, Kuznetsov immediately offers the option of planning the premises indicating the dimensions and it is shown as you can “enter” suitable models there. After all, the premises of baths are usually small and if the metal stove can be placed in it easily, then the dimensional brick is already problematic. And at the same time, many factors need to be taken into account: from where it will be drowned, where the pair and the hottest part of the furnace will be exit. And here the finished options are proposed. Very convenient and it is worth saying to the author many thanks! The furnaces themselves are put into a separate category and the BIC are marked.

The furnace project presented in this video is created using the blacksmith’s suggested principles for building furnaces. The first half describes the principles of controlling the operation of a specific model as well as the movement of gases and how they work. The masonry process is discussed in the second. An extremely helpful and educational video.

Masonry features: Materials and recommendations

For laying the case and chimney, the usual clay, full -bodied brick is recommended to use. M150 brand and above, size 250*120*65 mm. It is not difficult to calculate the number of bricks for Kuznetsov’s stoves: you need to multiply the number of rows of the model you have chosen by 0.8. This amount is enough to lay the body (taking into account the battle and the rejection). For the chimney you need to count separately. The calculation scheme is slightly different: you know how many bricks per row, multiply by the number of rows (each is different depending on the dimensions of the furnace and the height of the building), add 10% to the battle and get the desired number.

The Sh-5 (230*114*40 mm) or SB-8 (250*123*65 mm) is advised for a chamotum nucleus, if one exists. The scheme of takes into account its number. There are no points of contact in common between the corps and the core of Kuznetsov’s furnaces, making them incoherent. There should still be a 5–6 mm space between the chamotum nucleus and the two parallel walls, the case. You can wrap the completed core—which is typically placed first—into regular packaging cardboard of the appropriate thickness to make it more resilient. Instead, you can lay a heat insulator, like basalt cardboard, to improve the furnace’s thermal insulation.

Barbecku can also be constructed using the concept of large furnaces.

In height, the rows of masonry made of ceramic brick do not coincide with the height of the rows of chamot. They do not need to be adjusted one under another. It is important to maintain verticality and horizontal, track the angle, as well as the recommended seam width. And then everything will be as it should. In reality, the dimensions of ceramic bricks differ from the standard 250*120*65 mm. If the deviations are non -critical, you can adjust them with a seam. Therefore, when calculating furnaces and their heights, they take a height of brick with a seam. It should be 70 mm. But you can’t make a seam more than 7 mm, so look for bricks of suitable quality and size.

Above, at the points where the chamotte’s masonry finishes, there are gaps in compensation that account for various factors related to material expansion. It is important to keep an eye on them because the chamotis brick expands more than ceramic does, and without this space, the core will eventually shatter the masonry on top because of its stronger expansion.

Using a tag, cut from Kuznetsov’s stove’s guns

It is necessary to compute the gap’s size based on the order’s marks. The height of the final row of chamotte is marked on the drawings. You take into account the height of the ceramic brick wall yourself: multiply the number of rows by the height (70 mm) of a seam-containing row to obtain the required value. More than 10 to 15 mm of grain height is required. This is a compensatory gap that needs to exist. Stone basalt wool (not glassy, but with a use temperature above 1200 O C) is placed in the resulting void.

Bricks can be set in or on ribs of internal walls and columns, which are typically about a quarter thick. Make the more convenient choice; it makes no difference. There are instances in the drawings where a brick is positioned on the rib and in the same row. It must be driven to size in this instance (saw).

Additionally, there are subtle differences in the furnace casting installation locations. Because of the program’s features, a ceramic brick is shown in the drawings above the furnace door, but you have to put a shame on the rib there. Chamot plates carved into the voids created by the drop in height. Because of the varying temperature extensions, there is still a 5 mm space between the metal components and the masonry. This opening is filled with an appropriate heat insulator that can operate at temperatures as high as 1200 °C.

An asbestos cord was once used to insulate furnace castings from heat. I now suggest cardboard or basalt cotton wool.

Now for the solution: a clay or clay-sand solution is used to lay the housing (made of ceramic brick). Use pre-purchased compositions (refractory mastics) when constructing with refractory chamotes. It is not advised by Kuznetsov to wet brick prior to masonry. Use secondary raw materials only if necessary to accomplish this. Even if you don’t use the furnace right away, it still needs to be dried out right away. Should this not be completed, there will be a fuckery smell at the top of the furnaces.

Brick furnace construction involves many fine details, all of which make it very challenging. You can, however, construct Kuznetsov’s stove yourself using the author’s freely available guns and schemes. with suitable justifications and if a desire to complete everything exists.

Two -colp stoves Kuznetsov: Greeds. DIY Kuznetsov stoves

In 1962, the so-called "Kuznetsovka" first surfaced. These furnaces were invented by Igor Kuznetsov, who is still working to improve and develop them. Approximately fifty inventions have been made to date that span practically the whole spectrum of domestic furnaces. Let’s examine Kuznetsov’s stoves in more detail. The topic is highly relevant because the guards are in demand these days.

Than "Kuznetsovka" is better than others?

Consumers are always asking the question: why is it worth buying precisely these products, and not the one that is nearby. Quite a logical and logical question. We always look at the strengths and weaknesses of the products before buying, and only then draw the appropriate conclusions. As for Kuznetsov’s furnaces, they are famous for their high efficiency. As a rule, we are talking about such numbers as 80% or more. For example, a standard guide of 4 kW can warm a house with an area of 100 square meters. In this case, Western branded fireboxes should have a power of at least 10-12 kW. By the way, orders for Kuznetsovka from the USA, Sweden, Canada and a number of other countries are not uncommon. It is impossible not to mention that Kuznetsov’s furnaces (orderly) are “omnivorous”, that is, low -grade combustible materials, for example, sawdust can be used as fuel. It is also possible to install equipment providing hydraulic devices. At the same time, the operational characteristics do not deteriorate.

The basis is primarily

It was Kuznetsov who first used the automatic distribution of traction through the channels. This method is good because the carbon monoxide is excluded, so you can keep the vyushka open. The system of such chimneys is not only its unique, but also with simplicity. If the furnaces with a complex chimney configuration usually have an efficiency of about 60%, then the “blacksmithing” – 80% and above. In addition, the principle of free gas passage follows from here. That is why the guards are often compared with thermonuclear reactors. The fact is that the energy of the gases, unlike the gas at the gas, is not twisted into a whirlwind, but immediately impregnates the stove. Naturally, the secreted heat goes either to heating the premises, or on the hot water, depending on the needs.

Two -colp furnaces Kuznetsov: Graduation and its features

For a considerable amount of time, the idea behind creating furnaces that allow the law of free gas stroke to be applied has been understood. A stove with two legs is the most popular and widely used type.

The principle of its work is that the air from the environment enters through the blurry. At the first stage of combustion, when the lightest fuel fractions burn out, the process is somewhat reminiscent of pyrolysis. This regime is the most effective. But to Kuznetsov, few used these advantages. But the guesses have a design that allows it to work in pyrolysis mode. As a result, pyrolysis gases burn under the dome of the third cap. The process itself is interesting. Its features are that combustion is self -regulatory. If the flame is too dispersed, then the craving deteriorates, and the combustion process slows down, if the heat is not enough, the thrust increases, and the combustion process intensifies. Kuznetsov’s two -colp furnaces (orderly) have a second dome so that the combustion process is not violated. The temperature in the second cap in the efficiency of about 80% reaches 300-400 degrees, and this is enough to transfer heat to the coolant.

Multicapod furnaces

Frequently, multi-casual makes the typical cap. Every cascade consists of two caps with an opening from above. Since there is a free flow of gases and three cascades, you can refer to this stove as a classic order. Such equipment can operate at nearly 97% efficiency in firebox mode. However, practically speaking, the fuel is not a factor. Coal, fuel oil, or anything else can be used.

Generally, you can reach 90% efficiency with an even number of caps. Here, a lot relies on the fuel type and combustion conditions. Nonetheless, the primary disadvantage of this approach is the complexity of furnace maintenance. Frequently, issues arise when cleaning the caps of soot. Furthermore, the first cap (even quantity) is extremely tiny, the temperature beneath it will be roughly 1,500 degrees, which means the metal will not withstand it, and the weight’s lining is unstable.

As it is, we already know what Kuznetsov’s caps are. Often, the order is constructed at home. Let’s examine the steps involved and the things to be aware of.

Kuznetsov heating stoves: with your own hands

The primary purpose of the furnace must be identified before any work can be done. Let’s examine the typical heating apparatus with the most basic design. It is recommended that you construct Kuznetsov’s furnaces with your own hands as soon as possible using the house. If the building is already standing, the order can still be established; obviously, this is not ideal, but it is possible.

At the first stage, it is necessary to prepare the foundation. It should be made of concrete and have a width of 10-15 cm larger than the size of the furnace. This is one of the most time -consuming works that you have to do, so in some cases it makes sense to call a specialist. The foundation should not contact the base of the house, do not forget about it. Its absence is also unacceptable, since the floors will not withstand high load. Then it is extremely important to properly equip a chimney on the roof of the house. To perform these works, it is advisable to use laughter and tips of professionals. Let"s see how Kuznetsov’s stoves are being built. The guesses in their simplest performance are made quite simply and quickly.

Necessary material

Selecting high-quality materials is crucial; fireproof brick in particular. He needs to be able to tolerate heat. Consequently, stone brick is used for internal masonry. The drawing is used to determine its number. Ordinary brick constructions are frequently made in an effort to save money. This is acceptable, but the masonry becomes less durable. Clay brick M150 is suitable for external masonry.

Not possible to function without 100–130 kg of clay. Investing a little more money to purchase high-quality materials is preferable. In this instance, the clay will not break when squeezed and will last for a very long time. You require twice as much sand as clay. A mixture of clay and sand with a volume of 0.2 cubic meters requires about 500 bricks.

All that’s left are the metal accessories. This has two doors, a grate, steel corners, and a valve. Now, let’s examine the manufacturing process of the Kuznetsov heating and welding furnace gunshot.

Masonry and check

You won’t encounter any issues if you’ve previously laid furnaces. The ligament’s quality is the only thing that needs to be considered. It is essential to lay the wire in order to enhance this feature for every second row of brick. Placing ¼ brick on ¼ brick is the better way to lay a channel starting from the first tier. As a result, the furnace’s length will somewhat increase. In this instance, there are 17–18 tiers in the upper overlap between the tiers.

It takes some time for the solution to freeze at the end of the masonry. Doors and other metal products can then be mounted. It is only then that they begin the initial traction. At this point, the oven’s functionality is examined. Examine the traction, door tightness, valve tightness, etc. P. This is the only general layout that is known about Kuznetsov’s stoves. A DIY’s DIR-MECHIPLY may have varying powers.

Something else about masonry

Frequently construct Kuznetsov furnaces for the spa. Seldom is the order of this purpose constructed with your own. This is because the design is rather intricate. However, it should be recognized that a high-quality bath stove can accomplish a great deal of work. As an illustration, it heats a number of rooms, including steam rooms, dressing rooms, and laundry rooms. She also heats water, makes steam, and provides ventilation. Surprisingly, Kuznetsov’s bath stove is the only one that can handle all of this. There aren’t many significant differences in the order, but manufacturing accuracy matters.


Here, we looked at Kuznetsov’s two -colp and -caps. You don’t find your ideal girlfriend as frequently as you would like. These stoves are frequently seen in the villages and dachas. Because they take the shape of a fireplace, they can occasionally be purely ornamental in nature.

Nevertheless, it is important to pay attention to these heating devices. This is the best option for a country house due to its high efficiency when compared to some other stoves that are more expensive. In addition, you can construct one of these stoves on your own if needed. In this way, you can not only efficiently heat your house but also acquire invaluable experience.

That is all there is to it in terms of where and how Kuznetsov’s stoves are positioned. They’re well-founded guesses that will probably remain popular for a very long time.

DIY Kuznetsov bake: drawings of guesses and description of the stove masonry

AND. IN. Kuznetsov has been designing, producing, and enhancing furnaces since 1962. Over 150 distinct designs were created during this time, all of which aimed for the absolute performance indicator, or 95% efficiency. We will teach you how to make Kuznetsov bake using your hands in this article.

First image: Kuznetsova stove

The system that separates gases into hot and cold streams is the development’s key component. The furnace’s special cap causes the hot air to be delayed inside, and the cold air is expelled into a chimney via a different channel. The efficiency of useful action reaches its maximum when the cap stays in the cap and the heat is dispersed evenly within the case. In contrast, the efficiency of solid fuel boilers is 80%, pyrolysis is 85%, and regular furnaces are between 30% and 35%.

The fact that warm air enters the pipe with combustion products explains why most solid-fuel units operate poorly. Apart from the fact that the residual volume is not always sufficient for complete heating, the heat threshold is further decreased by rapidly released flue gases. Some constructions attempt to address this issue by lengthening the chimney, but doing so runs the risk of decreasing traction and, consequently, efficiency. The primary objective of Kuznetsov’s design was to create a unit that could enhance heat transfer and offer complete traction.

Video 1 shows how to build a heating furnace using the Kuznetsov method.
