Two -colp furnace Kuznetsov

It is known that Igor Viktorovich Kuznetsov. Its influence on the creation of novel heating device designs is immeasurable. The fundamental idea behind every "Kuznetsov bake" design is this: they work by applying physical laws that govern the upward movement of hot gases.

General idea of the device of a two -cape furnace

Furnaces that operate on the aforementioned principle have a rather straightforward design. This is a pair of caps positioned next to or on top of one another. In the instance at hand, a brick glass is referred to as a cap that has been turned upside down. The latter is held up by brick-built columns and walls. There are a few holes in the lower portion of the cap. The input is one of them. Warm gases pass through it. A weekend is the second. The cold gases disappear from here.

There is a cap on top of the circuit under consideration. The aperture for providing dialing serves as the exhaust pipe entrance in this instance. Spent gases enter through a unique vertical channel that runs from the bottom cap to the top. The firebox in the same cap, which has a design similar to a two-colp furnace, is equipped strictly in compliance with the regulations in place. As they move, high-temperature gases cool and transfer their heat to walls and supporting structures.

The principle of operation, which is based on the design

Warm gases in a similar design of the furnace for movement do not need to create traction. It arises due to the difference in weight that the layers of gas possesses, warmed up to different temperatures. The lightest, having the highest temperature, rise up, under the block of the cap. And heavy colds gather below the cap. At the same time, gases with intermediate temperatures move from the base to overlapping the cap and vice versa, creating turbulence. This contributes to the fact that the walls of the cap are heated much better. With an increase in temperature in the internal volume of the cap, excess pressure is created. It also contributes to the growth of heat perception by forming the walls. In this case, heat transfer is carried out due to convection. Thermal energy is moved directly by the gas jets. For stove models that function on electricity, the creation of traction does not need. If heating is carried out with wood, then combustion products are removed due to the formed thrust. In such cases, a certain volume of warmed gases, t, is formed under the set of the cap.n. "bag". It is an ideal option for the burning camera of diverted gases.

The main properties inherent in such a principle of work

A cap that has Colling stove, You can give any volumes and shape (there are implemented structures with volumes of 5.0 m3);
Thermal energy moves due to natural physical laws;
Inside the design of the cap, gas turbulence is formed;
Gases with the highest temperature are assembled under the arches of the cap;
Cold gases fall into the transition channel;
The increase in temperature under the cap leads to an increase in pressure;
In each arbitrarily chosen horizontal cross section, the caps of the cap is heated the same. The heating indicator grows when the lower horizons are moving to the upper;
A source that gives thermal energy can be placed anywhere in the lower zone of the 1st cap. This does not affect the nature of heating;
The presence of several heat sources is acceptable;
If the sequential placement scheme of the 1st and 2nd caps is implemented above the other, uniform heating of the structure is achieved in all horizontal sections of the structure. The cap, located below, perceives more energy, given by warmed gases than each next.

You can accurately calculate and design the stoves of the mentioned design by taking these properties into account.

The advantages of the two -colp furnaces of Kuznetsov

When discussing their work and IN. Kuznetsova, professional stovers use the all-encompassing term "forge." The primary benefits of the furnace designs taken into consideration, which account for their global demand, are:

Significant efficiency, the average indicators of which are 80%;
The structures allow you to obtain significant combustion temperatures of any type of fuel, without using materials and technologies that require their production in industrial conditions;
The versatility of furnaces that can work on a fuel of any type, burning it to the ash. In this case, the soot is practically not besieged;
Simplicity of care. Even soot burns in these furnaces, so you can clean them every few years;
Uniform heat transfer during the time passing between the furnaces is organically combined with a lower material consumption of the structure;
Structurally, it is possible to integrate the water heating circuit, which practically does not worsen the technical characteristics of the structure of such a stove;
Great traction using a minor length chimney. This simplifies and makes cheaper construction and installation of the furnace under consideration;
The appearance of the product can be given taking into account the overall design of the room in which the oven is laid out a two -colp circle. At the same time, its operational characteristics do not deteriorate;
The thrust through the channels is redistributed automatically at the stages of the transition from the furnace furnace to cool, which excludes the probability. You can practically not close. It is used in the vast majority of cases, only in emergency situations.

The latter is made possible by the stream of gases that emerge as a result of traction being directed through the lower channels and past the heated portions of the furnace body. Convective flows that are forming draw air into the furnace. This enables you to operate without the stove’s unique ventilation system when it is folded up.

When using a bit, the design of a two-cape furnace enables you to totally eliminate a number of issues present in stoves of other constructions. When the reverse traction happens, cold air can enter the furnace or some heat can be blown through in a strong wind. To be completely excluded, this is not found in any blacksmith. Airflows are directed beyond the components that he is able to project.

Possible design options

The great flexibility of such a system is its greatest advantage. A stove with the required functions can be designed and installed in a variety of shapes, sizes, and uses.

Perfectly installed in an existing cap are a water heater and an electric heater, an oven and a hob, a steam generator or a heat accumulator, thermal inserts that organize heating according to calorie type, etc.P. Projects with caps up to five cubic meters in size have been put into action.

Kolpak furnaces’ technology enables you to incorporate contemporary technologies into their designs, automate the combustion process, and modify heat transfer.

Similar stoves from buildings with different projects can be heated by using the recirculation systems that are already in place.

Kuznetsovka furnaces can be used to solve a variety of problems and are available in multi-story versions. Certain projects can run on electricity if they incorporate a low-energy consumption regime into their designs, since energy builds up at night.

It is feasible to install a boiler for heating or hot water in two-colp furnaces. Here, the combustion process occurs at elevated temperatures. This enables MAX to utilize all of the fuel’s energy. These furnaces use a unique heat accumulator to heat the material rather than the coolant, enabling more significant heating (from 4 to 6). Thus, such a system’s accumulating capabilities get stronger.

All of the main rooms are simultaneously heated by the designs of bath stoves, which also provide ventilation, warm water, and prepare pairs of the necessary quality—including dry overheating. Certain models enable you to control the TVR in the bathroom, swiftly heat any space, operate its heating, and more.

Features of work

The blacksmiths serve several purposes. Every model has gotten warmer. The same kind of heating is accomplished using either electricity or wood as the energy source. The entire structure is fully heated. Simultaneously, you can experience the functioning of the open fireplace, which permits the possibility of cooking pancakes over the coals (without having to flip them), as well as barbecuing or using Russian heat. In the latter scenario, any food can be prepared.

Another feature of these stoves is their technical quality. The temperature at which the chimney walls warm up increases with the length of time the typical stove is used. As a result, less heat is released from the flue gases that are on display. As a result, they are removed at a higher temperature, decreasing the working furnace’s efficiency.

All excess heat is collected in the bag of the upper cap in two-colp furnaces, and extending the firebox’s duration has no discernible impact on the decrease in efficiency, t.To.

Some masonry tips

Prior to starting the furnace’s laying process, the order is calculated. A different article addresses a query about the laying of a specific model.

Here are some general tips for installing a two-cape furnace technologically.

External masonry should be carried out by clay single brick 250*120*65. It is recommended to use the M150 brand and above. The firewall elements of masonry are made of fireclay bricks of the SHB-8 brands (250*123*65), or Sh5 (230*114*40). The recommended width of the seams of the external masonry should not exceed five millimeters.

The approximate amount of the required brick, without taking into account the needs of foundation and pipe laying, is determined as follows: the column of bricks necessary in order to lay out the first row should be multiplied by the number of rows (according to the order) and by the filling factor (for such furnaces it is equal to 0.8). The resulting amount is quite enough for laying the furnace, including culling, as well as a possible battle. A brick will be required on the pipe, the number of which is calculated as follows: 4-6 pieces per row, taking into account the required pipe height. The need for a fireproof brick is considered to be individually, according to the order.

The indicative thickness of each row, assuming exterior laying with regular brick, is 70 mm (five millimeters for the seam).

When purchasing a shamic brick, you should insist on a certificate due to the likelihood of getting a less expensive, acid-resistant one. In terms of appearance, they are nearly identical. The latter, however, doesn’t have very hot temperatures. Make an effort to use a soldering lamp to heat the brick’s tip. simultaneously resistant to acid will crumble.

Using fireproof brick in the same installation as regular brick is prohibited. Their coefficients of thermal conductivity and linear expansion differ. Consequently, such masonry loses integrity when heated.

It is not advised to use chamotis brick for external furnace wall construction. Its propensity to overheat raises the design’s fire risk.

Remember that the chamotoma brick expands to a considerable length and warms up more quickly and strongly than regular brick. To account for thermal elongations that occurred in both ordinary and refractory masonry, a five-millimeter gap is left and filled (to select a stove):

in width and length – cardboard (mulodic heat -insulating, basalt and t.P.);
in height (seams arising between masonry and installed stove devices) is filled with kaolin, or basalt wool.

Regarding insulation and heating for your house, Kuznetsov’s two-coal furnace is a viable option. For homes looking for dependable and affordable heating options, this furnace’s dual coal-burning capability and effective design provide a number of benefits. Utilizing coal, a cheap and easily accessible fuel source, the Kuznetsov furnace reduces energy expenses while producing steady warmth. Its cutting-edge two-coal system guarantees ideal combustion, lowering emissions and having a smaller environmental effect. Furthermore, the furnace is a sensible option for improving the comfort and energy efficiency of any home due to its robust construction and simple operation.

DIY Kuznetsov stoves

The low coefficient of productivity in most furnaces is caused by their lack of structures. This is the outcome of smoke gases being produced too quickly. Lengthening the chimney can solve the issue, but doing so will lessen the intensity of the combustion and the subsequent craving.

DIY stoves for Kuznetsov

The primary duties involved in designing a brick furnace are:

providing good traction;
increasing heat transfer of the entire volume of the generated thermal energy.

Finding a "middle ground" between these tasks is necessary to ensure that the smoke persists for as long as possible without compromising the thrust. Kuznetsov’s stove is one of the best fixes for this issue.

Design features

DIY stoves for Kuznetsov

Depending on the function they perform, all of the currently operating Kuznetsov furnaces—more than 150 in total—can be categorized into multiple groups:

bath;
hob (for cooking);
heating;
grille;
fireplaces;
Complex.

Crucial! Among them, combined coastal structures are the most common.

The stoves mentioned above operate on a single principle. Right behind the top-down camera is the air cap, which separates hot, smokey gases. This time, the input hole is below instead of above like it was previously. The warm gases in the cap rise to the top and cool down, allowing the heavier gases to escape. Hot gases quickly cool down and exit the cap in a similar manner.

Today’s skeptics believe the technology described is ineffective because the delay in smoke should cause the traction to deteriorate. Actually, everything is incorrect, and it’s not hard to see how this viewpoint is false.

The air vacuum under the cap is 0.18 HRA, which in relation to normal pressure in the atmosphere can be considered a negative value. Hence the natural convection.
Another important point is an open door blown. It seals an air flow that regularly replaces the sparse air under the cap.
The length of the pipe also plays an important role. This is the air pipeline that passes the entire stream of smoky gases and, therefore, providing the maximum speed of their movement.

Crucial! Kuznetsov’s oven allows you to supply hot water in addition to enabling individual heating. The steel heat exchanger on the back of the cap serves this function.

What can give such a strange chimney?

Stratification of smoky gases in temperature immediately after a combustion chamber.
On the way of gases, you can install not one, but two or three caps at once. As a result, the smoke will give more heat, and the design itself will consist of several zones with a permanent temperature.
The cap is located next to the firebox and smoky gases that have not yet given their heat fall into it. As a result of ash, carbon monoxide and flying hydrocarbon, which are carried away in a regular furnace, in this design are burned out under the cap. This leads to an increase in heat transfer and minimizes the number of soot in the chimney.
Thanks to natural convection, combustion products are physically unable to leave the stove before they give all the heat.
The heat exchanger in the Kuznetsov oven, unlike other types of design, is located in the cap, that is, outside the furnace chamber. He cannot affect the temperature of fire and, as a result, does not reduce the efficiency.

Let’s go straight to the building process now.

What is required of work

To complete the full set of measures, you will require:

Brick is full -bodied, 754 pcs.;

DIY Kuznetsova stoves: construction technology

Even for those who are building a stove for the first time, it is quite easy. It is crucial to follow both the order and the construction technology.

Phase 1: Basis

When the furnace base is installed concurrently with the house foundation, the size of the furnace base only needs to match the chosen structure. However, in the event that no one is present, it is preferable to pour independently and create a slightly wider (12–15 cm) area of the future building rather than combining it with the main foundation.

He and Kuznetsov recommend laying a silicate brick foundation that is dull in color.

Crucial! It is advisable to consider beforehand where the chimney should be located on the roof and within the room. It needs to adhere to specific specifications (see drawing). Then and only then can you start building.

The picture below shows the Kuznetsov oven’s comprehensive instructions.

Chamotis brick needs to be laid out in rows No. 1 and No. 2. The most important thing here is to avoid using a solution that was used earlier to lay the groundwork. The smoke channels can be turned on with row No. 2, but it’s best to add a little more thickness to the furnace’s bottom.

Four cleanings are installed for the smoke channels that enhance heat transfer: one in the back, one that was blown, one on the side, and one on the third. The construction level and corner are used to check horizontal and verticality, and the length and width of the purges are determined individually.

Crucial! Brick halves in the masonry may present the biggest challenge. The use of a grinder is recommended for better cutting results.

Along with all the internal partitions, the wall forms the boundary between the blower and the remainder of the furnace. A gallop is installed while row No. 5 is being laid.

Kuznetsov pastry. Masonry

The overlap of the caps is constructed in ranks Nos. 17–18, and No. 21 leaves two passageways that walk along the left and right internal walls.

Building a Kuznetsov stove is generally fairly easy and presents no difficulties if one has visual enforcement on their hands.

Putting the Kuznetsov oven together

Step 3: Inspection

The first kindle must be lit at the conclusion of the masonry. The design is slow because the least amount of fuel is used. The performance of the furnace will be examined concurrently with its firing, along with the tightness of the valve and door joints. Even the smallest flaws should be fixed right away if they are found.

Crucial! The specified design’s maximum power of 10 kW is sufficient for a typical rural home.

What else should you know

A dry seam, defined as a vertical gap, joins the furnace chamber to the cap. Convection flows moving in both compartments necessitate such a constructive solution. To enhance the combustion of volatile particles and create turbulence, a portion of the smokey gas with a lot of steam is held back in the combustion chamber for an additional cycle.

Air was introduced into the blown through the grate and via openings in the walls that allowed air to enter from above. Once more, this is necessary for the full combustion of volatile particles because, when the air enters through the grater and reaches the upper portion of the torch, it essentially contains no oxygen.

A catalyst is a refractory brick grate located above the furnace chamber. It reaches extremely high temperatures and effectively burns whatever is left over after the fuel is not completely burned.

Colling stove laying tips

You can not make a top -down camera part of the cap, t. To. fuel should burn in limited space to create a fairly high temperature. If you connect the cap with a furnace, you will get a traditional Russian stove, but with a bad thrust.
Firing should begin with a minimum temperature, gradually increasing the intensity of combustion.
At high temperatures, the brick expands, due to which the internal chamotum box can “hang”, that is, an empty space forms from all its sides.
At the end of the masonry, it is advisable to cover all the bricks with a special refractory composition.
Each second row of masonry should be laid with steel wire to strengthen the ligament.
Doors and other metal elements should be mounted taking into account the fact that they expand at high temperature. To separate the metal with brick, you need to use a special gasket.

As a conclusion

The most basic shaft-doped structure is visible as well.You can construct Kuznetsova by hand. But, you should get in touch with knowledgeable stoves if installing a multifunctional stove is planned or if the styling technology seems overly complex. They will complete the task swiftly, considering every detail, and the final design will last for many years.

Kuznetsov furnaces: device and principles of work, advantages, variations, drawings

Not just stove enthusiasts are familiar with Kuznetsov’s stoves; many homes in Russia and overseas are heated by them. AND. IN. Kuznetsov assembled a solid group of like-minded individuals around him and began working on improving furnaces in 1962. See rice for the team’s more than 1.5 developments, which cover practically the whole range of domestic furnaces.

The furnaces and IN. Kuznetsova, among others

Many would like to fold some of Kuznetsov’s furnaces with their own hands, and this article is to help them. But we are not going to reveal some hidden secrets of "forge" – they simply do not. On the site of Igor Viktorovich Stove.ru who want to find a huge array of stove information for free: from information on the design and construction of furnaces to detailed drawings and recommendations for installing a furnace in the house and device of the blind area around the building with stove heating. We also do not intend to criticize or correct something in this household encyclopedia: we before and. IN. Kuznetsov in the stove, to put it mildly, far.

This article’s goal is to provide a sort of overview of Kuznetsov’s settings so that readers can easily navigate the source material. Allow us to illustrate the necessity of this with an example.

Suppose I am a car mechanic-universal with extensive experience and I want to convey it to others. The car is a complex thing. If I start to be distracted in the course of the presentation, explaining in detail that as an overflow and a caster (let us say, readers are not quite kettle, now everyone is driving) affect the controllability and waybill stability of the machine, and the gas distribution diagram-the fuel consumption depending on the roads conditions, and so on in the same spirit, in the end I will get confused to the point that I myself will stop understanding how the car works, on which I drive. Willy-nilly, I will have to state the material, albeit “on the fingers”, but in professional fluid.

To experts, though, it will be difficult to read it even for me, and in general, amateurs will avoid amateurs. I will therefore require assistance from someone who I can loosely refer to as "receipt." He is actually not a kettle at all; he is capable of installing the valve pushers and adjusting the suspension on his own. However, in this instance, his job is to explain how the car’s entire filling is put together as a single unit under the guidance of the maxim "steering, gas, brake to brake."

A similar situation occurred in the USSR in the late 1950s and early 1960s when industry started producing cars for general public sale. Then "How the Car Works," that era’s best-seller, was released. edited by none other than A. Lipgart, the principal designer of the fabled Victory.

Information “from the receipt” will not yet allow you to start work: it does not give deep knowledge that will allow at least intuitively to pretend along the case the necessary values of numerical parameters. But it is essentially fundamental: owning it, the professional text is already read with understanding and faster. And, if somewhere something is not clear in it, this no longer causes loss and throwing, but simply a mark in the mind: this must be found out more about this.

There are currently no epoch-making policies regarding furnaces and furnace heating that the government has adopted. However, their importance in home heating systems during the energy crisis cannot be disputed: a heating furnace with a mass usage efficiency of 70% will already save fuel for the state. Highway heat loss of 35% is installed in new heat center projects, and there is currently no way to lower this amount. As furnace knowledge becomes more and more common, you will need to escape on your own without becoming Kuznetsov or Lipgart. Okay, let’s give it a shot.

Why – blacksmiths?

But is it worth it, particularly for Kuznetsov’s furnaces? It’s because their worth justifies it. From the start, Igor Viktorovich saw the Russian stove not as a treasured artifact from the past or an ostentatious luxury item, but rather as an essential component of the future—that is, the present—of economic energy. When the fried rooster pecked, the others realized what it meant.

Consequently, a 100 square meter home can be healed by a blacksmith for 4 kW, just like a 12 kW firebox with a "from there" brand. Which, incidentally, doesn’t mention the creation of the eternal engine but rather how branded advertisers carve out their own paths after possibly spotting a "path of happiness." Regardless, the truth is that Kuznetsov consistently receives orders from countries that are not in the stove’s tail, like the USA, Canada, Sweden, and Finland. The benefits of the forgeousness specifically are as follows:

High efficiency – 80% for Kuznetsov’s furnaces is not marvelous.
High fuel combustion temperature without the use of technologies and materials requiring industrial production.
As the first consequence of the previous one – omnivorous. In the blacksmiths, any fuel burns to the ash, and the precipitation of soot is minimal.
The second investigation is simple care: t.To. Saja burns out, Kuznetsov’s stoves can not be cleaned for years.
A lower material intensity in combination with uniform heat transfer between the fireboxes: in a city apartment with central heating, the temperature fluctuates more during the day than in a house heated by a blacksmithing at 2 firegies per day.
Wide possibilities of embedding a water circuit without a deterioration in the technical parameters of the furnace.
Good traction with a short chimney, which reduces and simplifies construction and installation work when building it.
Plasticity of the structure and appearance as a result. Further): not a deteriorating furnace, it can be designed for almost any room and design requirements.
Automatic redistribution of traction through the channels when moving from fluid to cooling, which guarantees from the fucker: the pack is almost never required to close, it is provided for more for emergency operating modes.

Note: invented and. IN. Kuznetsov method of redistribution of traction in the root differs from the well -known gas vyushka. According to it, the stream created by the traction passes past the heated parts of the body of the furnace with special lower channels, and when the flame burns in the furnace, convection from it pulls the flow of air over itself. As a result, a separate system of ventilation system is not required. In addition, a gas break in a reverse traction when blowing into the pipe, or, conversely, stretch out in a strong wind, and in the blacksmith any flow of air will pass by everything that he could work out.

The basis of the basics

The concept of free gas passage is provided by the majority of Kuznetsov’s furnace advantages. Let’s use an example to clarify once more.

Imagine a stove with a complex smoke system: a loss, four to five revolutionary Dutchwoman. Strong twists will inevitably arise in this close maze. Heard how to bake? This is only a slight manifestation of the rings raging in it. And she has nowhere to get there, except from the laying of fuel. If the channels are quite long and narrow, then at first glance there is nothing terrible here: vortices, while getting to the pipe, dissipating, cooling, and still give their energy to the body of the furnace, and it – into the room. But in fact, the nuances are manifested, which will be discussed later in the text. Because of them, the efficiency of the canal oven over 60% is an exceptional rarity.

In the channel furnace, while it is heated, a huge flow of energy is rushing about, and you can, without violating its work, take only a small part of it on heating or heating water. Such a stove is somewhat similar to a nuclear reactor. Do not be scared, only in synergetics, t.e. By the ways of energy circulation in it. In the nuclear reactor, you have to lay fuels ten times more than necessary to ensure project energy output. Otherwise, neutrons will simply fly out, not having time to meet the atoms of uranium ready to accept them. In the channel furnace – hot vortices, not having time to cool, fly into a pipe or, conversely, cooled immediately, giving smoke and soot.

However, in synergetics, the Kuznetsovka (more on that later) is already getting closer to the thermonuclear reactors of the future. The term "thermal unit" conjures up images of a hydrogen bomb, but that’s all. Teromyuclear reactors are actually very safe.

Why? Since they generate precisely the same amount of energy as the consumer should, they only require a small amount of technological power to power the sparse plasma. The plasma will cool down before it reaches the room’s walls and be fully visible (there are no heavy atoms in it) in the event that the Tokamak or Stellarator camera collapses unexpectedly. Repairmen swear that, regardless of the duty officer’s decision to sharpen, they will be able to endure liquidation without protective funds after five minutes.

So what do thermonuclear reactors and Kuznetsov’s furnaces have in common? What Because of the free passage principle, the energy from the flue gases impregnates the furnace body instantly rather than scrolling through the stream several times before pushing through. With the exception of the room and/or water heating register, she is now stuck there.

First: cap on the cap

The idea behind creating a furnace that enables the benefits of free gas stroke has long been understood. This furnace has two caps, and the device diagram is displayed in rice. First, let’s examine his left pose.

Plans for a pair of collp furnaces

The blowing 1 allows outside air to enter the firebox 2. The firebox may be fitted with a Hale tapering nozzle, which produces a gas blossom in a single-cape furnace. The heavy, outside, cold air does not get a chance to "on blowing," much like water in an overturned glass, because the light heated gases beneath their pressure cap prevent it from doing so. However, a gas blossom caused by thrust from the second cap is frequently unstable in two-colp furnaces. As a result, Kuznetsov rarely had two-colp stoves built.

Near the most efficient pyrolysis, burning takes place right after kindergarten, when the lightest and most energetic fuel fractions burn. They are specifically made for pyrolysis in the Kuznetsov furnaces. Gases used in pyrolysis burn out below the first cap’s set 4. The burner of a furnace used exclusively for pyrolysis is comparable to the subtive space of the first cap.

The pyrolysis burning beneath the cap regulates itself; if the fuel is extremely flared up, the burning gases’ "pillow" expands downward; an upward flame does not result in a set of caps. As a result, it is challenging for smoke gases to escape because they descend. As such, traction becomes less strong and combustion slightly decreases. It’s the other way around if the combustion is decreasing.

When coal is burned in inactive mode or toothal, both caps function merely as heat receivers in channel furnaces, absorbing the fuel’s residual heat. However, in the Netherlands and Sweden, it is primarily "whistling" into the pipe because, as per Bernoulli’s well-known hydrodynamic law, the flow rate will be higher in a narrow channel. Additionally, leftover gases beneath the caps will gradually revert until their heat is transferred into brick.

Reminder: In windy channel furnaces, you frequently need to remove any remaining smoldering coals from the firebox and shut off the bit to prevent the heat from "seizing" and the fuel from burning to ash. There is no negative impact in the caps of this negative impact because the wind cannot enter the furnace due to the sharp expansion from the chimney into the cap, and you can simply wait for the fuel to finish providing the final calories with energy.

A two-colp stove that is perfect in every way. The second cap and her body number five are then at the same moment. Additionally, beneath the arch, there is an invisible zone of thermochemical reactions 6. It neutralizes the carbon monoxide residue and nitrogen oxides left over from the furnace’s much higher combustion temperature than that of a flame furnace. Chimney 7 only receives carbon dioxide and water vapor.

While a circular brick stove can be folded, arranging the doors in a two-colp stove is challenging, and cleaning it can be challenging (once, yes). Consequently, if you draw an analogy with electronics, two-colp stoves are actually operated in accordance with a cascading sequential scheme rather than a parallel one. The second cap is placed on top of the first, and chimneys (or a single continuous wide gap) are used to connect the caps between them from the furnace’s rear, at the right position. The brick furnace’s efficiency decreases simultaneously by only 1-2 percentage points, as shown in Fig.

Note: The ring gap of the L2 between the first and second caps should be wider than the same L1 between the firebox and the first cap in order to ensure that the gas brush is stable in the round two of caping gas, barring hurricane winds.

In both scenarios, you can integrate any kind of water-heat register in the second cap without any issues. Under the first cap’s set, the furnace body’s primary heat is transferred. This, incidentally, is also one of the reasons the two-capacity was not in use earlier: at the time, using the kitchen trough for dishwashing was standard procedure, and with cheap fuel, a small gain in efficiency did not offset the difficulty of the work.

Fuel costs have increased, and living standards have become more demanding. The second cap then dropped by accident. The combustion mode will not be disrupted, regardless of the amount of heat beneath it that does not enter a water heater because the high-temperature cascade from parasitic heat loss is reliably isolated by the first cap from the brick’s poor heat conductivity.

Simultaneously, the gases beneath the second cap are appropriate because they have sufficiently cooled and reacted to allow the heat exchanger to be constructed from regular structural materials without running the risk of burning them or causing soot to accumulate on them. Conversely, at 80% furnace efficiency, the temperature in the second cap will be between 200 and 400 degrees, providing just enough of a temperature gradient to effectively transfer heat to water.

A multi-cash stove can, in theory, be performed in a round cap; each cascade consists of two caps with a hole in the vault and a deaf above, as demonstrated in rice. A stove with a free gas stroke (left position in Fig.) and three cascades (6 caps) can be used to create self-building under any fuel, from fuel oil to duck, and achieve an efficiency of 97-98% in any furnace mode. But it can’t be analytically precise, and computer modeling needs a powerful enough hardware and software platform.

Plans for furnaces with multiple blades

Oven with even (with a hole in the vault) caps brought to its pod. In Fig.), capable, in principle, to show the efficiency of 85-90%, depending on the combustion mode and the type of fuel. But both of the one and the other, firstly, is very difficult to clean. Secondly, the first cap is very small, and the temperature under it will be quite pyrolysis, about 1,500 degrees. No metal can withstand it, except for platinum. Tungsten and he will burn like a thread of a bulb with a broken flask. But will there be a lining for pyrolysis furnaces on the weight, no one has determined the experience yet.

Not metal structures, but black dashed lines in drawings. The diameters of the chimneys and the separation between the lower wrappers of the caps from the are forming the corresponding dimensions (parabola and straight).

Second: thermal load

Nothing is operational based only on concepts. The theoretically perfect stove needs to be executed in the material correctly in order for it to gnaw well, dry, and cook. This indicates that there should be a significant thermal load on the material in relation to caps, and particularly to two -colp. Building a massive structure with thick walls is similar to lighting a bonfire inside a cave. You must sit right next to the fire in order to feel warm, and soot will be present.

Examine Fig. Drawings and orders for a few of Kuznetsov’s furnaces, including the bath, heating-welding, double-circuit boiler, and improved Russian with a stove, are included. Despite not being an experienced stove, it is evident that the Kuznetsov furnace uses 1.5–2 times less material per unit of released power (500 W*kV. m of the outer surface) than traditional methods.

Placing a Kuznetsov furnace order

On the one hand, having a brick that can hold a lot of money is a good thing. However, it also necessitates the cautious advancement and observance of construction technology (see below). The thin brick wall will already be destroyed with an accelerated fireplace due to thermal load, which is the same force that keeps a pile of cobblestone from moving.

The knowledge of building mechanics is also crucial for Kuznetsov furnaces. When the thickness of the clay solution decreases, the wall’s strength does so much more quickly than it does with cement-sand. As a result, the foundation for these stoves needs to be built with extra care and strict adherence to the author’s recommendations. They must be closely adhered to when building.

Note: AND. IN. Kuznetsov permits unrestricted personal copying of their materials for building purposes, but objects to reprints. Still, images on rice. tiny. The master knows where to find complete drawings, while the amateur won’t build anything on them. We therefore hope that Igor Viktorovich will pardon us for this small favoritism.

Third: step to the right, step to the left ..

In Kuznetsov’s furnaces, high loads on the material necessitate not only careful structural development but also adherence to some basic design principles. The floating firebox from the shamic brick of the SHB-8 or Sh-5 brand is the most notable of them. The ceramic brick brand used to construct the furnace’s body is no less than M150.

What is meant by the floating firebox? First, there ought to be a dry seam all around it or in the locations that the author meticulously designed. Making it is not so easy: after laying out the final row of chamotte (unless otherwise indicated in the stove’s specifications), a clay solution from the joints between the chamotis and regular brick is selected, and mineral cardboard—basalt, kaolin, etc.—is inserted in its place. P.

Construction modules that are related and unrelated

Secondly, the principle of module incoherence must be adhered to strictly. What’s that, rice is shown? Even with damping seams, no chamotte’s protrusions should fit into the grooves of regular brick. The chamotte’s heat capacity and TKR are very different from those of a "brick," and when the masonry is tramped on, the furnace attached to the furnace body will shatter it. The "Kuznetsovka" firebox ought to be a small module set inside a nest of regular bricks. The author provides a detailed explanation on the website about how to set up her access to the chimney.

Additionally, it is imperative that you adhere to his suggestions for material preparation and selection. "Kuznetsovka," despite being made of brick, is high-tech and suffers from the same negligence and replacement of Erzatsi as a rocket or submarine, substituting tin for titanium and composite materials. Though they won’t be as dire, they will still have to deal with them at home rather than reading about them in the news. and make the payment with cash.

By and large, thanks to technology: Kuznetsov’s stove can produce a neat, industrious, and hardworking novice. However, a very skilled stove, with a half-drum, who is carelessly setting up an exceptionally nice plate, or a Dutchwoman, is undoubtedly uneasy using Kuznetsov’s oven.

However, the "Kuznetsovka" is not some unfathomable miracle. Numerous masters’ and lovers’ profiles already exist, both re-creating and modifying Igor Viktorovich’s original designs. A drawing can be found in Fig. on the right, and in rice. One of them is listed in the section’s order.

She has two characteristics. The 21st row’s initial trampled moves. They are included in the work when it is being tramped upon, accelerated, and facilitated; they bear a striking resemblance to Kuznetsov’s idle passions. Their throughput prevents gas output during flame or flowering, and gas traffic jams drown out these tubules.

Bricks from the 17th, 28th, and several other ranks were second-sawn along the way, and even at the corner. In actuality, bricks do not hold up well, as both stovers and basic builders are aware. However, this belief was held during a period when the term "corner drill," which is also Bulgarian, was not. All they had heard about was the diamond instrument, which is allegedly used in some secret military factory workshop.

However, a brick cannot be cut with a grinder by weight alone because the tool’s play in the hands will cause its strength to drop dramatically. First, install the tool in the bed using a lever that moves in a vertical plane to obtain a cutting machine. This is one of the two options. You can do this yourself; the materials are available for purchase.

The stove Kuznetsov made himself

If there is a circular on the farm for at least 1,500 Oppin, and ideally between 2500 and 3000, then another approach is appropriate. Then, rather than using a regular saw gear, the diamond circle on stone is tucked into it. This is a better option because it provides a supporting board with a corner emphasis through a much more precise and clean cut. Additionally, you can finish on the opposite side without running the risk of running into the saw with a high step.

While round furnaces are not very practical in homes, they do have many advantages in theory. The exceptionally high efficiency of round multi-colpaces, however, may prove to be a deciding factor in this situation given the high demand for small, mobile furnaces. This is because the law of the square-cube causes the efficiency of a furnace to drop sharply as its size decreases.

Naturally, metal would have to be used to construct such stoves. This eliminates the need to clean the stove because it is collapsible. However, there is a very small range of metals that are suitable in terms of heat capacity and thermal conductivity. Only cast iron is among the cheap options, but it is delicate and heavy.

There is, nevertheless, a stronger, easier metal material with comparable qualities. These are powder metallurgy products. It makes perfect sense in regard to the "powder rubbish" knives, but powder parts might be a great find for the furnace where nothing works for a while.

One of the previously mentioned issues is the heat-resistant lining found on the first cap’s arch. If it can be resolved, perhaps Igor Viktorovich Kuznetsov’s efforts will bear more substantial and far-reaching results than they appear to be right now.

Kuznetsov’s stoves: these stoves, which heat a lot of homes in Russia and overseas, are well-known for their design, functionality, benefits, and modifications.

A good choice for home insulation and heating systems is the Kuznetsov two-coil furnace. Because of its creative design, which provides effective heat retention and distribution, it is an affordable option for homeowners trying to cut back on energy use and heating costs.
