Colling stove Kuznetsova Scheme

A suitable heating solution is essential for keeping your home warm during the cold months. Investigating alternate heating techniques can be helpful if you’re trying to save money on energy bills or are just looking for a more effective way to heat your space. A technique that is becoming more and more popular is the Colling stove Kuznetsova Scheme.

The Colling stove, sometimes referred to as the Kuznetsova Scheme, provides a special method of heating that blends conventional wisdom with cutting-edge invention. This stove design was created by Russian engineer Ivan Kuznetsov with the goal of maximizing heat distribution and retention while consuming the least amount of fuel. In contrast to traditional heating systems, which frequently depend on electric heaters or centralized sources, the Colling stove functions independently, making it a flexible choice for a range of home configurations.

Fundamentally, the purpose of the Colling stove is to heat the surrounding area by means of convection currents and radiant heat. A number of baffles and channels in its design direct hot air through the stove, resulting in effective heat transfer to the space. The metal and firebrick used in the stove’s construction also aid in efficiently absorbing and radiating heat, providing warmth long after the fire has gone out.

The Colling stove is unique in that it emphasizes sustainability and energy efficiency. Compared to conventional wood-burning stoves or furnaces, this stove can drastically cut fuel consumption by optimizing combustion and heat circulation. This results in lower carbon emissions and a smaller environmental impact in addition to cost savings for homeowners.

In addition, the colling stove’s small size and adaptable design allow it to be used in a variety of living environments, including bigger homes and apartments. It is also usable by homeowners with different degrees of technical proficiency due to its straightforward but efficient operation. The Colling stove is a promising option that blends efficiency, comfort, and sustainability, whether you’re looking to add a new source of warmth to your home or retrofit your current heating system.

A little theory

Despite their positive distinctions, traditional handmade stoves with hobs—both "Dutch" and "Swedes"—share a single characteristic. This natural chimney thrust has an impact on the thermal devices’ efficiency. Without traction, the bulk of well-known furnaces cannot operate; solid fuel boilers also made significant progress in this area.

Let’s make a reservation: none other than Kuznetsovskaya, as only Igor Vladimirovich’s creation needs a natural push to work.

The two Kuznetsov collp furnaces are unique from the others due to their efficient operation, which is based on the principle of free gas flow, which does not require external energy.

This theory is explained in great detail and is easily accessible in articles that the inventor has posted on the pages of his own website, www.Stove.ru. Additionally, there are projects with operational furnaces in the public domain. We will briefly review the theory and draw comparisons between the processes that take place in the cap of a solid fuel burner and the conventional method. Thus, traction in the chimney is what allows air and combustion products to move in a typical or Dutch-style channel furnace.

An external factor operating in dependence on natural traction is:

• the height difference between the entrance to the pipe was also blown;
• the difference in the temperature of the outer air and smoke gases;
• wind load.

That is, if the damper is open, traction exists even when the heater is off. When the stove is in operation, the gas rate increases significantly and the thrust intensifies more frequently. Consequently, a large amount of air enters the furnace, lowering the temperature of combustion and reducing the effectiveness of burning firewood. By restricting airflow through a damper, we make fuel smolder in an oxygen-starved environment, which is also not the best condition for obtaining thermal energy from wood.

The ideal, highly efficient stove should absorb as much heat as possible from combustion products to prevent them from shooting out the chimney. This is not so simple to put into practice, and here’s why:

• With an open damper, the hot gases quickly move through the brick channels, not having time to transfer the walls to the walls;
• If you cover the damper, then the flow rate will decrease, but the channel material is not able to absorb all the released warmth and transfer it to the room, so part of the energy still flies into the pipe.

These factors make it rare for the efficiency of practically all currently in use furnaces to reach 60%. Both issues have been successfully handled in the Kuznetsov development; the fuel burning and heat-release efficiency are both at a level of roughly 80%. Not every boiler that burns solid fuels can produce this kind of indicator. AND.IN. Kuznetsov described the fundamentals of building furnaces in line with the free gaping of gases principle, which we shall address later.

Kuznetsov oven scheme

We provide a crude example to help you visualize the furnace’s operating principle. Envision a modest bonfire in a public area. Although there is unrestricted air access, the combustion temperature is low and heat dissipates randomly in all directions. The nature of the process will change, but the bonfire won’t go out if you cover the flame with a large vat or cap and leave enough lumen below.

Naturally, the hot gases will rise to the vat’s upper zone, where they will obstruct the unrestricted flow of outside air. They will only cool, sink to the opening, and eventually move outside to make way for a stream that is warmer when heat is applied to the vat’s walls. As a result, the combustion zone will fill with as much air as is required to burn the fuel. Until warm gases cool down on their own, cold air cannot replace them; this process is self-regulating.

The main point is that when building furnaces using the Kuznetsov system, two caps connected by a vertical channel are used instead of just one. The goal of this modification is to address the issue of the heat effectively being transferred from the burning to the room’s space. High-temperature combustion products rise beneath the first cap’s set, warming the walls. As a result, the gases cool and start to descend due to gravity and the pressure of the furnace’s rising hot stream.

In enhancing the procedure and.Kuznetsov went one step further and created the technique for separating the temperature flow of the gas at the outset of the process, right after the fuel. In order to accomplish this, a partition that stops short of the vault divides the area inside the cap from the furnace. As a result, a hot flow enters the upper zone. In Kuznetsov’s furnaces, a dry seam for gases with a lower temperature is meant to be positioned in the partition as a gap of a specific size. The stove diagram below illustrates the main steps in the process:

As a result, a continuous turbulent gas flow with a uniform temperature distribution forms beneath the first cap. As a result, more air cannot enter the oven than is necessary, and hot products under the vault and partition will not be "not allowed." Under these circumstances, the fuel burns completely, leaving the departure consistent with the ash.

The same movement takes place in the second, upper cap. As hot gases rise beneath the vault and continue to cool, low temperature products are slowly descending and transferring energy to the walls made of brick. Once they have cooled, they tumble down the vertical divider and into the chimney.

There is continuous gas pressure in the upper and lower caps, which encourages natural movement and eliminates the need for a chimney.

Varieties of Kuznetsov’s furnaces

The guests of Kuznetsov’s Office (available for public access on the developer’s resource) can be categorized into the following groups:

• Bath stoves (series BIK);
• Brick boilers for heating and heating water for the needs of the hot water (series of KIK);
• heating furnaces (OIK series);
• heating-welding stoves (OVIK series);
• Other (bread, calorifers, greenhouse and Russian stoves).

Think only about the two most common types of furnaces: bath and heating.

Bath stoves

The natural flow of gases between two caps is still the basis for the Kuznetsov bath furnaces’ operation. In addition, a stump needs to be properly warmed up in order to produce high-quality steam. The developer suggests that the best technical solution is still in use today, with the oven’s stone filling made of heat-resistant steel. Right above the fuel is where you’ll find the oven.

All of the surrounding rooms are heated in addition to the steam room’s interior using the thermal energy stored in the lower and upper caps. The water coil is positioned so that it is simple to replace or repair beneath the first cap. Examining the furnace drawings will reveal the installation location.

Along with ready-made bath stove modifications and.IN. Kuznetsov offers suggestions for their appropriate installation, based on the arrangement of the space to select the optimal choice. Additionally, there is the option to select from a variety of developments, including more substantial models with large tanks for water heating as well as tiny stoves for cramped small baths.

Water heating stoves

Of particular interest are the contemporary Kuznetsov stoves with water heating from the Kick series, also known as brick boilers. This is actually a brick cap with a good efficiency of roughly 70–80%, making it comparable to its iron “brothers”. We explained above how such a high efficiency is achieved.

Depending on the power, one or two steel pipe registers are integrated into the furnace’s body. The capacities of ready-made boiler modifications are 17, 34, and 63 kW. The author also provides double-circuit models that have the ability to heat water for domestic use. In their suggestions for building these heaters, and. According to IN. Kuznetsov, basalt fiber insulation should be used on a brick boiler’s body to improve operation efficiency.

A contemporary technical solution has been incorporated into the majority of furnace domes to ensure that a combustible component of smoke gases burns. For this reason, secondary air supply is arranged under the upper cap vault or elsewhere, depending on the design. Such a thermal device will act as a furnace for pyrolysis when wood of the corresponding quality is used.

Conclusion

We have presented a wealth of theoretical knowledge regarding the "blacksmiths," but putting the theory into practice in brick and mortar and then in the thermal device is a more difficult task. The inventor or another member of his team can be more helpful in consultations on this topic. If you have the desire and some stove experience, Kuznetsov’s cap, which you made yourself, will amaze you with its flawless craftsmanship.

What are Kuznetsov’s caps – guesses and masonry tips

In Russia, people are familiar with Kuznetsov caps. They heat many country homes, along with Russian and Dutch stoves, giving people the warmth and comfort they need to live comfortably. These heating appliances are rather new. In the middle of the previous century, they were developed. We will only cover the essential details regarding Kuznetsov’s caps; the order and comprehensive laying advice are always available on the internet.

Features of "blacksmiths"

The "forge’s" primary characteristic is that it was developed using traditional Russian stoves as a model. The end result was a design that outperformed the most widely used contemporary boilers in terms of effectiveness.

Among the furnaces’ primary characteristics are the following:

1. High efficiency – at least 80%, and sometimes higher.
2. The possibility of using almost any type of fuel.
3. Minimum precipitation of ash and soot.
4. Simplicity of operation – the first cleaning, such an oven will require years of active use after.
5. The ability to embed a contour for hot water supply.
6. Short chimney.
7. Widespread design opportunities – the furnace can be designed in accordance with the features of any room.

Principle of operation

The idea of free gas passage serves as the foundation for the operation of Kuznetsov’s caps. Due to the significant swirls that form in the furnace, any conventional stove will buzz during operation. Although they don’t cause issues, vortices drastically lower the heating device’s efficiency. Rarely does this indicator go above 60% for conventional stoves. Hot, twisted air enters the chimney and either swiftly cools, forming a lot of smoke and precipitating soot, or it enters too quickly and cannot provide the stove with the necessary warmth.

Crucial! Practically no twisters form in the "Kuznetsovs". The heat from the smoke gases enters the room and the furnace almost instantly. The primary distinction between "blacksmiths" and conventional stoves is this.

Through the blow, outside air enters the furnace. The firebox of single-colp structures is equipped with a unique nozzle that forms a specific type of gas. In the two -colpacular ones, there is a craving from the second cap, which makes the vowel unstable. Following the burning of the lightest fuel fractions, the stove enters a mode that is similar to pyrolysis. Gases used in pyrolysis are burned beneath the cap’s vault.

The stove became self-regulating with the cap. Pyrolysis gases cannot expand upward due to the cap; instead, if the fuel flares up too much, the expansion happens downward. As a result, there is less of a result and less combustion. The opposite process is seen when fuel combustion is reduced.

The oven caps start to function as heat receivers when the fuel is completely burned off, or when the coal is dotted. In contrast to Dutch or Swedish furnaces, the gases collected in this manner stay under the caps until they pass the brick’s heat instead of going to the chimney. Since there is little chance that heat will enter the chimney, Kuznetsov’s caps rarely need to be closed at an angle similar to channel structures.

Constructive differences of "blacksmiths"

Although there are many variations in Kuznetsov’s capture design, a circular stove is thought to be the best. It is possible to identify the following benefits of this design:

• Simplicity of masonry. The order is so simple that even a “kettle” that has minimal skills can cope with the construction of the furnace.
• The body of this design is a cap.
• A zone is formed under the arch where thermal reactions occur, and carbon monoxide is neutralized.

Although two-colp devices are more effective, setting up the treatment doors in them can be challenging, as the order and actual experience running these furnaces demonstrate. Thus, there will always be a variety of challenges connected to cleaning.

This disadvantage can be reduced easily: a system of chimneys connects the caps, which are arranged in a cascading pattern one above the other. This essentially keeps the furnace’s efficiency unchanged while making its operation less complex. A hot water circuit can be mounted thanks to this design, which embeds the register beneath the second cap.

It is possible to multi-colp-packed stunt round stoves. There are two caps on each cascade. There is already a three-casual design with six caps that works with any kind of fuel.

Such different "blacksmiths" ..

There is a huge variety of caps. Among them are the following designs:

• heating;
• heating-welding;
• bath;
• with a lounger and t. P.

It shouldn’t be too big for any of them to function well. The traditional stoves require 1.5–2 times less masonry materials than traditional "blacksmiths." From one perspective, this is undoubtedly a significant benefit. Conversely, though, the structure’s design needs to be well considered. If not, the stove will topple over during the initial firebox test.

Generally, ceramic brick is used for the furnace’s body, and chamot is used for the furnace itself. The firebox has a floating construction, meaning that the so-called dry seam is completed around it. To accomplish this, mineral cardboard gaskets are placed into the empty space left by removing a clay pantry from the joint between ceramic and chamotis bricks.

Since the characteristics of ceramic and chamotum bricks are very different, it is imperative that the modules be kept apart to prevent the masonry from "tearing" when the furnace is operating.

Types of kolpak furnaces

The intended purpose of each "forge" varies, as previously mentioned. It is common to differentiate between the following types of them:

• Hobs. The main goal is cooking.
• Heating. These stoves, as can be seen from the name, are designed to provide the house with heat.
• Heating and welding. These are combined structures that perform two functions – the heating device and the hob.
• Bath.
• Bread. Another combined design, which is most often combined with a hob or heating-welding.
• Street. These are whole furnace complexes. The simplest designs can be a regular barbecue.
• Multifunctional constructions. Are developed individually based on the needs of the customer.

The construction of the Kuznetsov oven

Bruser House Plan

Without even needing to be an experienced stove, Kuznetsov’s stove can be constructed on its own. With any work, the project comes first. Prior to choosing the right option, it’s important to determine the stove’s functional purpose. All of the house’s rooms should receive consistent heating from the heating furnace when it is installed.

Must consider the chimney’s location as well as any supporting building structures. Kuznetsovka needs a foundation that is well-equipped. It is typically constructed of concrete. The foundation’s width should be roughly 10 cm greater than the furnace’s future footprint.

Several useful tips

1. Interior masonry is done on a rib of refractory chamotte brick.
2. The masonry is enhanced by a wire laid through 2 rows.
3. Metal elements are installed with a gap providing compensation for expansion.
4. Metal elements are best separated from brick with special gaskets.
5. After the masonry is completed, the structure is processed with special refractory compounds.
6. Accelerated firebox is performed at a minimum temperature.
7. Subsequent fireboxes – with a gradual increase in temperature.

Interfering with drawings, ordering, or making changes is not advised, particularly if you were not required to complete the masonry of furnaces earlier. Using the original guards Kuznetsov developed is the best option.

• Chamotum brick for internal masonry. To reduce expenses, you can do without it – this is permissible, but not desirable.
• Ceramic brick for external masonry.
• Sand-clay panting mixture-it can be purchased ready or mixed on your own.
• Metal elements – a gate, a furnace door, blown, a grate, a wire to strengthen the rows, steel corners.

Conclusion

Despite their many features and benefits, Kuznetsov’s stoves are still among the easiest to install, which makes them intriguing. The stove can construct a typical home master who has never worked with masonry with just the help of a good author.

"Kuznetsovka" for everybody. They will serve the purposes intended for them and look good in any space. In contrast to contemporary, widely used boilers, a cap is a heating device that is both efficient and, crucially, cost-effective in both construction and use.

• KOBKAKOVACE KUZNETSOVA: a simple design for building with your own hands

They know about caps not only in Russia, but also far beyond its borders. Along with the design of the channel type, they heat many houses, striking even experienced stovers with their efficiency and performance. Unfortunately, about their creator – and. IN. Kuznetsov, not everyone knows. But on the account of the inventor of more than one and a half hundred of different designs, so loved by the owners of suburban dwellings for extraordinary convenience, unpretentiousness and comfort. The technology developed by a famous stove all allows you to build heating devices in modern houses, while receiving not only high -quality heating, but also a stylish addition to the interior. Within the framework of this article, we will talk about the secret of the success and design features of unique heating units, as well as share your own technology for the construction of one of the most popular dome furnaces Igor Viktorovich Kuznetsov.

Features of Kuznetsov"s caps

Kuznetsov’s furnaces skillfully blend modern technology with age-old Russian customs.

Popularly referred to as "Kuznetsovka" or "Kolpakovka," Kuznetsov’s caps have higher thermal dedication and efficiency than other solid fuel units. In terms of heat engineering, the development of the well-known stovenik has an efficiency close to 80%, whereas the widely-known Russian furnace has an energy efficiency of more than 60%. The majority of Kuznetsov’s development is based on the entirely new principle of gases inside the furnace, which made it possible to achieve such significant performance indicators.

Warm combustion products travel through the network of channels in all previously known designs, losing heat as they pass by heating bricks. Simultaneously, a strong traction is necessary for the furnace to function normally; otherwise, the gases from the working area are halted, which degrades heat exchange. Furthermore, a stove enters a gas generator mode and starts to smolder and smoke when the working chamber’s increased pressure creates a barrier to the air entering the hearth.

Characteristics of gas flow in dome furnaces

Kuznetsov’s use of the principles of free movement of gases suggests an entirely different approach to heat exchange. Step selection of heat from ascending hot flows is produced by a number of rods-caps inside the heating apparatus. Higher-temperature gases replace the combustion products as they descend in temperature. Just visualize this process clearly by keeping in mind the behavior of a smoke stream thrown into an upside-down glass. It rises at first, makes contact with the bottom and transfers heat to it, then dissipates and descends along the walls.

Of course, Kuznetsovka is much more complicated, and the processes that occur in it are more multifaceted than in the example described above. Nevertheless, it is precisely due to the fact that the movement of hot masses occurs naturally, it is possible to achieve amazing economy and heat transfer. As for the traction, it would seem that the delay in smoke in the furnace dome should lead to its deterioration. In practice, natural convection inside the cap is ensured not only at the expense of the chimney, as in channel furnaces, but also due to the air storage under the arch, which is facilitated by the high temperature of the combustion products that rush there. As a result, the performance of the structure will provide even a shorter chimney, which is required by any Swedish or Dutch furnace.

Solid fuel heat generator colliding in the given

I must admit that the lack of a gas trading system contributes to an increase in the heat transfer of "blacksmiths," in addition to the more efficient convective heat transfer technique. The Bernoulli thermodynamic law states that in domed units, the acceleration of the gas flow in narrow channels is not affected because the furnace’s mouth immediately behind the chimney passes into a wide cap. Because of this, hot gases from burning firewood remain under the caps for a considerable amount of time instead of going to the chimney, providing residual heat and reducing daily temperature fluctuations.

To the question of whether the stove can function without forced traction

Numerous benefits flow from the furnace’s more sophisticated design:

• less materials for construction are required;
• Less solid particles are carried away with combustion products, so it will be much less common to clean the walls of the heating unit;
• the ability to install a short chimney;
• work on almost all types of solid fuel;
• unpretentiousness in operation – domed furnaces require maintenance much less often than channel;
• the presence of free space inside the furnace allows you to install a hot water supply circuit;
• uniform heating and heat transfer for a long time;
• Quick exit to the operating mode.

It is hard to ignore the fact that Kuznetsov’s furnaces, with their original design, offer a plethora of options for interior design. They function as a sort of bridge between the high-tech appliances of contemporary homes and the cozy "tube" Russian stoves.

Kuznetsov"s heating and welding oven is a very compact heating device

Home dome heat generators come in a variety of designs, and IN. Kuznetsov can accomplish several things.

• Heating stoves are used to heat residential premises;
• hobs Designed for cooking and heating food;
• Bath created for heating baths and saunas;
• External Installed in recreation areas. Stoves of this type are divided into heating and universal (with a hob, barbecue, cauldron or barbecue);
• Bread allow you to make any pastries and are often combined with hobs;
• Fireplace In addition to the main purpose, aesthetic function is also performed.

As you can see, the list of "caps" is quite extensive, albeit it does not include every unique combination of furnaces and special-purpose units created by the renowned designer and its ascetic.

Design and principle of action

The expression "all ingenious – just!»Fully applies to the design of the dome furnace, which allows you to realize the advantages of free gases. The simplest two -colp unit presented in the drawing on the left works as follows. The air necessary for the burning of firewood enters through 1. The firebox 2 is performed in the form of a tapering nozzle, so it is possible not to pass the outer air beyond measure. Otherwise, he will immediately go into the second cap, dragging heated gases. It prevents the flow of severe cold air and the so -called gas backbone, which is formed under the dome. By the way, due to a simple design, the atmosphere installed inside the furnace is often unstable-it is thrown by thrust from the side of the outer cap. That is why two -colp stoves, known long before the birth of Kuznetsov, were not popular.

The two-cape furnace’s basic working principle

During the active combustion of firewood, the combustible gases that have not had time to oxygen in air rise under the dome of 4 inner cap 3. There they are ignited under the influence of open flame and high temperature. We can say that a zone is a zone under the cap, similar to the one that is formed in the burning chamber of a conventional pyrolysis furnace. It is also important that the process of pyrolytic combustion regulates itself – with a very intense flame, the outflow of combustion products is difficult, and accordingly, the thrust is reduced. If pyrolysis gases burn out, then the process is restored. At the same time, no less important processes occur under the arch of the second cap. In this zone, nitrogen oxides and carbon monoxides (carbon monoxide) come into reaction, which, as a result of reactions, break up into safe components. With proper operation of the dome unit, the chimney goes mainly water vapor and carbon dioxide.

Caps serve as drives when firewood burning ends, trapping heated air masses beneath their arches. In Kuznetsov furnaces, residual combustion products devote all of their energy to the brick walls, in contrast to channel furnaces where they just "fly out into the pipe."

For a two-colp furnace, a round unit would be the best choice. In this instance, the heating device’s body could serve as the upper dome’s functional component. Regretfully, the practical challenges in constructing a heat generator of this type stem not so much from their spherical shape but rather from organizing cleaning and hatching for upkeep. As a result, a broad channel that goes through the furnace’s back connects the caps. The scheme on the right also reflects this feature.

Installation of the water heating circuit integration into the stove is done under the second cap’s arch if needed. This procedure has no detrimental effects on the fuel’s combustion regime or the system’s thermal balance.

The efficiency of this type of efficiency can be further increased by installing multiple cascades, each of which has two caps. However, because of the complexity of installation and the increased requirements for the lining’s heat resistance, amateur stoves do not typically use such constructions.

Kuznetsov’s plan for the most basic oven

Furnaces are developed using the same principles of the natural movement of hot gases that were previously described.Kuznetsov, IN. The numbers on one of these units’ above scheme show: One is the furnace chamber; two is the so-called dry seam; and three is the inner dome.

Heat exchanger No. 4; upper dome No. 5; chimney No. 6. As you can see, the lower cap and the firebox are integrated into a single area and are divided by a thin channel known as a "dry seam." As a result, the ideal environment for the unrestricted flow of hot gas into the internal dome and burning zone—and the cooled area toward the furnace—could be established.

Calculation of domed heating devices

Without delving into intricate thermodynamic computations, we provide the most practical stovers with a wealth of work experience and dozens of functional heating devices in the asset, rather than theorists who employ the most complicated method of calculating the cap.

The room’s heat loss will need to be calculated if one of the current structures is to be used as the foundation. This can be accomplished by calculating its volume using the outside wall and ceiling dimensions. You can measure the internal dimensions and add doubled wall thicknesses to them to make your task easier. They multiply the value of the premises’ cubature by 21, which is the average value of thermal losses for one cubic meter of total volume, after receiving it. The furnace’s power should be 15–20% higher than the results.

Designed to heat a two-story building, the dome furnace

Now as for the case when for any reason none of the projects found is satisfied with you. There is only one way out – to create a heating device on your own, based on the general principles of the construction of capacious furnaces and ways to determine their internal size according to the proportion method. All that is required is to correctly determine the external dimensions of the heating unit. The calculation methodology in this case is also not difficult. First of all, the heat loss obtained must be divided into 300 – thermal power, which can be removed from 1 sq. m of the outer walls of the furnace. In this case, only active surfaces are taken into account, that is, those that are directly involved in the heat transfer. In this way, the area of the walls located above gallops is obtained. Having added the quadrature of the rest of the furnace to them, they receive the total area of a solid fuel heat generator. Its height and width are determined according to the ratio of the structure taken as an example.

There are instances where the outcome is an excessively large unit. It doesn’t matter; since the stove will be submerged in water in the morning and evening, it can be safely lowered by 25–30%.

You should be aware that a double firebox will never provide twice the heat transfer when building a more compact stove. A forty to fifty percent increase in thermal energy is the maximum that can be attained. Therefore, those who value aesthetics and precision will need to accept that the heating device’s economy has decreased.

Regarding the dry seam, it is executed at a width of 2-3 cm. The lower value is considered appropriate for building daily-operating units, while the upper value is appropriate for building "weekend stoves," which are placed in dachas, hunting houses, etc. D.

As stated in the introduction, we now bring to your notice the elegance and technology involved in creating an authorship oven that is easy to make but incredibly popular. Kuznetsova, IN. Its 10 kW of thermal power is sufficient for a medium-sized house.

Arranging one of the most widely used designs ever created. Kuznetsov, IN

What will be needed for construction

Note right away that it is best to avoid using any used brick when building the furnace. Its operation is not best suited to constant temperature changes, and if you use material with fatigue stresses, it’s possible that the furnace walls will just start to crumble into the dust after a few years. So, what needs to be ready for the project’s implementation:

• Full -core brick of red clay M 150 in the amount of 754 pcs. – for laying the housing of the heating device and chimney;
• sand, 150 kg;
• small fraction clay, 130 kg;
• Brick fireproof – 63 pcs. which will be needed to arrange the kernel of the furnace;
  Most often, chamotomic bricks of the Sh-5 and SB-8 stamps are most often found. In our case, it is better to take the latter, since its dimensions are fully consistent with the size of the red brick.
• Puncher door, 1 pc.;
• Top door, 1 pc;
• doors for cleaning channels, 6 pcs;
• Golden grill, 1 pc (the minimum size is 250×375 mm, which can be drew from individual grates);
• steel wire for dressing rows;
• metal corner;
• chimney valve, 1 pc;
• asbestos cord or basalt seal – to seal the locations of cast iron casting.

If you’ve ever done bricklaying, you should be familiar with the following tools:

• Kelma (trowel);
• a container for the preparation of the solution;
• building level;
• plumb and cord;
• bushhammer;
• Mixer for mixing the mixture (you can use the nozzle for electric drill or prepare a solution manually);
• roulette;
• pencil.

If trimming brick for the furnace’s front side is necessary during construction, a grinder fitted with a stone and concrete cutting disk is the most effective tool for the job.

Preparatory work

Decide on a location, design, and chimney placement before beginning construction (both in the room and on the roof). Following that, you can begin to arrange the furnace’s base. A general foundation is poured if the heating unit is constructed alongside the house. When the stove is installed in the living room, a portion of the floor that falls on the "blacksmith" must be removed. In this instance, the furnace’s external base shape should be 10–15 cm larger than its actual dimensions.

Choices for installing a chimney on top of a cap

In order to lay the foundation, a 20–25 cm deep recess is made, into which a 10-cm-thick sand pillow is poured, filled with water, and rammed. Subsequently, the structure is filled with concrete, formwork is erected around the outside, and a 5 cm-high reinforcing mesh is laid. After the masonry has finished setting, which takes two to three days depending on the temperature, you can start working on it right away.

In addition to pouring the base, before starting the masonry, it will be necessary to prepare the solution. To do this, take pure clay and sifted river sand. Clay is poured into a large metal container, kneaded and soaked in a small amount of water. After it is well deoxidized, the sand is added and the consistency of the solution is brought to the state of a very thick sour cream. Most often, stovers use the proportion of 3 parts of clay per 1 part of the sand, but the correct ratio of the components depends on the type of clay – the higher its fat content, the more you need to add sand (up to the ratio of 2: 1).

Prior to beginning work, it is preferable to print instructions on paper so that you can follow them without having to spin each row as it is laid out. The lining layer installation locations receive special attention; on the diagrams, they are distinguished by dotted lines or other colors. Refractory material should not be substituted with regular brick, as this will result in a stove that is not only inaccessible but also short-lived.

In this article, we delve into the innovative "Colling stove Kuznetsova Scheme," a method designed to revolutionize home heating and insulation. The scheme offers a practical solution for households seeking efficient and cost-effective ways to stay warm during colder months while minimizing energy consumption. By combining the principles of traditional Russian stove heating with modern insulation techniques, the Colling stove Kuznetsova Scheme not only provides effective warmth but also ensures better distribution and retention of heat within the house. This approach not only reduces heating expenses but also contributes to environmental sustainability by lowering carbon emissions associated with conventional heating methods. With its blend of tradition and innovation, this scheme presents a promising avenue for enhancing home comfort and energy efficiency.

How to build a stove using a clock scheme with your own hands

1. Red brick makes up the first and second rows. It’s crucial to keep in mind that clay solutions are the only materials used to build furnaces; cement is not suitable in this context. The "blacksmith"’sbottomcan be made thicker if desired; this will only help with the lower portion’s thermal insulation.

First row laying is completed.

2. Starting from the second row, the chimney channels display and mounted. In the front and right side walls are installed door cleaning doors. It is important to set their frames by level or plumb line, otherwise the structure will look untidy. Fastening metal elements is carried out using steel wire (preferably galvanized) laid in masonry. Since the metal and brick have a different coefficient of thermal expansion, when operating the stove, the seams adjacent to cast -iron elements will be cracking. To compensate for the displacement of structures during heating, a layer of asbestos or basalt wool with a thickness of 5-6 mm is laid between the stove casting and the brick walls.

3. The door of the blow must be blocked by Row No. 4. A metal corner crossbar is used as support for the upper bricks and is positioned on the opening’s side walls.

Brick seams used in furnace construction should be thicker than those used in other structural structure construction. The reason for this is that the heating unit’s components have to have their thermal expansion taken into account, as their temperatures vary.

4. Commencing with the fifth row, chamotical bricks placed on the rib are used to create the working area’s fire-operating lining. It is preferable to use chamotomes for the masonry instead of regular clay since it won’t fade in the presence of high temperatures. The grate is installed at the same time. This is where you have to complete the first dry seam; it’s marked in blue on the order. To do this, the masonry’s clay solution is removed after the chamotte is laid in precisely the right locations, and the resulting gap is then filled with gaskets made of kaolin, basalt, or another mineral cardboard.

Chamotis brick is used to designate the area with high temperatures.

5. The furnace door installation in the sixth row is noteworthy. If you find aesthetics to be equally important as functionality, it is best to use the original stove cast iron, which is available in large quantities at building supply stores.

6. In a manner similar to the previous one, the internal channel construction of the furnace is continued by closing a top-end opening on the ninth row after the overlap. It will be helpful to remind you once more how important it is to use a bubble level to ensure that the masonry is level.

7. Catalyst columns are constructed in the furnace’s interior at levels 12 and 13.

8. There is overlap in the heating unit’s lower cap.

Auxiliary cords positioned at the corners of the building will assist in handling the workload of an inexperienced stove.

9. Construction of the upper cap with internal heat exchange channels is beginning with the 19th row. Additionally, four doors have been installed here for cleaning.

10. Pay particular attention to the 28th row’s chimal channel valve. It will be necessary to prevent the stove from cooling down in between the burners.

Eleven. A chimney is constructed beginning with number 31, and the nearby 29th and 30th form a vault of the upper dome.

There’s always something to aim for, even though it’s possible that you won’t succeed the first time in something so beautiful.

The first kindle is done after folding the stove. It is not advisable to fill the fuel tank to the brim right away; instead, heat the fuel slowly to prevent the masonry seams from cracking. The stove may smoke a little during the first few minutes of the test launch until its internal volume is fully heated. In the future, fuel-related smoke emissions are unacceptable, and their appearance indicates a disruption in construction technology. The furnace is tested in all of its modes after it has warmed up and fired up, and its exterior components are examined for tightness.

What should be taken into account during construction

Convection flows in both chambers must be coordinated, and this is accomplished by the dry seam connecting the firebox to the cap. The high water vapor content combustible gas is drawn into the fuel for re-burning, enhancing the furnace’s thermal indicators and causing turbulence to form in the atmosphere.

Air enters the fuel chamber through the furnace’s walls’ channels as well as by blowing through them. Because of this, more oxygen, or secondary air, is needed beneath the cap in order to burn the pyrolysis gases. Since all of the oxygen will fade at the top of the flame when using the full combustion grate alone, full burning will not be achievable.

Since the fireboxes are positioned above, in the area of high temperature, only chamotis brick is used for the installation of catalyst columns. They burn everything that rises beneath the dome to warm up.

In light of some aspects of the cap’s design, allow me to offer some basic advice.

1. The furnace chamber should not be part of the dome. All the salt of Kuznetsov’s structure is that firewood should burn in a small chamber – it will be much easier to create a high temperature necessary to complete the processes of pyrolysis. If you combine the furnace and cap in one space, you will get the most ordinary Russian furnace, which will also smoke due to bad thrust.
2. The stove firing begins with chips, adding fuel in small portions for several hours.
3. Due to various temperature deformation coefficients, the chamotum firebox can break the outer red brick box, therefore, deformation gaps are necessary in the places of mutual adjustment.
4. To strengthen masonry, segments of steel wire are laid in longitudinal seams. It is not necessary to carry out the dressing constantly – it is enough to strengthen every second or third seam.
5. Experienced stovers do not recommend soaking brick before laying.

Lastly, we would like to point out that you should only make any modifications to the design if you are confident in the accuracy of the changes and are familiar with the procedures involved in the caps. If not, using a "improved" heating device could be risky in addition to being ineffective.

Especially in areas with colder climates, the Kuznetsov stove cooling scheme offers a novel solution for home insulation and heating. This system efficiently redistributes heat throughout the house by utilizing the principles of thermodynamics, guaranteeing consistent warmth throughout the winter.

The simplicity and affordability of the Kuznetsov stove scheme are two of its main advantages. Because it uses easily accessible materials like bricks and concrete instead of traditional heating systems that rely on gas or electricity, this method is more affordable and suitable for a larger variety of homeowners. The stove’s design also makes installation and maintenance simple, which lowers overall costs.

Furthermore, by reducing heat loss, the Kuznetsov stove scheme encourages energy efficiency. The system minimizes the amount of heat transfer from the stove to different rooms in the house by carefully placing ducts and channels, which lowers the demand for additional heating sources. By lowering carbon emissions, this not only lowers energy costs but also advances environmental sustainability.

Moreover, the Kuznetsov stove scheme makes a house more livable and comfortable overall. Residents can have a comfortable home without worrying about drafts or cold spots by keeping the temperature constant throughout. This is particularly helpful for elderly people, families with small children, and anyone who is sensitive to temperature changes.

To sum up, the Kuznetsov stove cooling scheme is a workable and effective way to heat and insulate residential buildings. Its ease of use, low cost, and energy-saving qualities make it a desirable choice for homeowners looking to lower heating expenses and increase comfort. Households can contribute to a more sustainable future while also enjoying warmth and coziness throughout the winter months by putting this innovative system into place.
