What is a stove of long burning, where it is used, its advantages and disadvantages

An additional camera for the purpose of burning fuel-released gas is installed in a heating structure known as a prolonged burning furnace. The heating of the room takes anywhere from a few hours to a full day in such a furnace because the combustion of the furnace material slows down during that process.

Wood coke and pyrolysis gas are produced by the fuel in the furnace as a result of constant temperature. The gas reacts with oxygen by burning more intensely and releasing a significant amount of thermal energy, which is enough to heat the water as well as the surrounding air.

Furnaces with extended burn times are furnished with a separate gas combustion chamber.

Long-burning stoves are different from conventional constructions in that they are designed to provide a dosed oxygen supply from above rather than below.

Long-term burning stocks are used to heat barns, outbuildings, private residences, garages, workshops, basements, and chicken coops. These heating structures are also utilized in industrial settings, depending on the size and level of modernization of the structure.

These heating structures are also known as stoves of long burning in colloquial language.

Because of their usefulness, these efficient heat sources have become very popular. These stoves do, however, have a number of advantages and disadvantages.

Table: Advantages and disadvantages of prolonged burning furnaces

• economy; It will take much less furnace material;
• efficiency; prolonged heat production is ensured when laying a small amount of fuel; These structures have a high level of efficiency, which exceeds 85%;
• design dimensions; Stoves of long burning make different sizes;
• simplicity in operation;
• For stoves of long combustion, you can use both solid and liquid fuel.

• complexity of the construction of the chimney;
• The design is not designed to connect a chimney system with many bends to it; In the process of combustion of fuel, intensive production of condensate occurs; Therefore, stoves of long burning should be equipped with chimneys that provide construction with high thrust;
• In the process of burning liquid fuel, there are many soot and other harmful residues of burned fuel;
• In order for the stove to work in economical mode, it is first necessary to melt it as usual;
• long burning stoves are not universal. It is necessary to decide in advance which fuel will work for a stove – on a solid or liquid.

Types of prolonged burning furnaces and their choice for independent manufacture

Typically, bricks, metal, or stone are used to build these stoves. can be square, cylinder-shaped, round, or asymmetrical in shape. Views differ according to the long burning furnace’s design and fuel burning technique.

Classical stove long burning

A classic design is one in which flames spread from the bottom up, forcing burning gases through layers of furnace material. These kinds of furnaces have a burning chamber with an additional air supply and a heat exchanger installed. Prominent examples of this kind of stove include the long-burning Bulereyan (Breneran) stove, Butakov’s stove, and modified structures with various heat exchangers.

Curved pipes inside the furnace body serve as the heat exchanger in Bulerian furnaces.

Minute stove for long burning

A mine stove is another example of this kind of structure. The combustion zone has been moved to the golus portion of this design. Heat transfer occurs when fuel-burning products pass through the adjacent compartment and burn out. It has been established for many centuries that this species is best built using bricks.

The combustion zone in the shaft-type oven is situated directly above the grate.

Famous stove

This is an upper-burning design where the fire starts in the upper portion of the furnace material and spreads outward in the opposite direction. Special air delivery channels should be included in the furnace because such a device needs an oxygen supply beneath the burned layer. Numerous options that you can create with your hands are made possible by the design’s efficiency, functionality, and simplicity. In this instance, used cylindrical tanks will be used as the raw material for its construction. A stove known as Bubafonia is a remarkable illustration of this kind of heating apparatus.

Use the old gas cylinder as a case for a homemade furnace.

Gas -generating stoves

Stoves or buildings that produce gas and burn pyrolysis gases in addition. Two factors influence the furnace material’s burning in this design: a high temperature and little oxygen. Combustible gases are released as a result, and they burn out in a separate chamber. Although the designs of these stoves are the most challenging to produce, they are more efficient and user-friendly than the alternatives.

In a separate chamber above the fuel, pyrolysis gases burn out.

A burlielyan oven is regarded as a cross between a wood-burning stove and a potbelly stove. You can read about the working principle of this unit and find detailed installation instructions in our upcoming material: The document named Pech-Buleryan-Svoimi-Rukami.HTML can be found at aqua-rmnt.COM/Otoplenie/Documents.

The design of the furnace, its features and the principle of action

Prior to moving forward with the furnace’s independent manufacture, it is essential to thoroughly examine each of its features.

The furnace should have a high heat performance if it is meant to serve as a unit for heating a large space. For instance, you should select a furnace that can heat up to 200 m2 for a 150 m2 house or room. You can’t be completely sure that the house will be warm in every corner without this "reserve" of power.

It is important to keep in mind that not every room is close to the heat source, so heating it will take longer and use more energy from the heating device.

The furnace does not need to have the designated "reserve" if it is intended to heat a space that is between thirty and fifty square meters. Since there won’t be many heat leaks in a space this size, a modestly powered unit will suffice. Its maintenance will be considerably simplified by automatic fuel refueling. It is feasible to include cooking hobs in the construction of a stove like this. In the event that the furnace serves as both an interior fixture and a heat source, windows can be constructed out of refractory glass.

Features of the design of prolonged burning furnaces

The structural characteristics of prolonged burning heating devices set them apart from other furnaces:

• The furnace chamber has a volume for loading a large amount of combustible material;
• The body of prolonged burning furnaces is equipped with a large door;
• The furnace compartment in the furnace housing is divided into two cameras; One camera is designed for smelling of combustible material, the second – for combustion of gas;
• The design of such a furnace provides for the presence of a special chipper, which prevents the flame from entering the chimney;
• This element of the furnace frame is made of a metal plate, which is welded at the upper part of the furnace compartment.

Differences of ordinary and pyrolysis furnace

You must contrast the operation of a long-burning furnace with that of a conventional furnace in order to comprehend its basic mechanism.

Heat is released into the room through the furnace’s heat outlet and surface. Due to the fact that the furnace material is ignited from below, the flame expands and ascends. This results from a significant volume of air entering the combustion chamber. Because the fuel in this type of stove burns quickly, the temperature in the room fluctuates, dropping and rising.

Another is the long-burning furnace’s operating principle. When firewood is placed atop it, the fire grows downward and only reaches the burning area with air supply. The result is a long-lasting, uniform release of heat as the material smolders. Apart from the furnace material, pyrolysis gas is released and acts as a fuel, producing additional heat.

While fuel burns rapidly in a conventional furnace, it smolders slowly during pyrolysis.

Almost any makeshift method can be used to manufacture furnaces. You will discover how to create a barrel-infused long-burning potion in our upcoming article: Aqua-mont.COM/Otoplenie/Burzhujka https:// -Dlitelnogo-Goreniya-Prostaya-Konstrukciya-Dlya-Azgotovleniya-Svoimi-Rukami.HTML.

Necessary materials and tools

To fabricate a furnace with a long burning time, the following supplies are needed:

• metal barrel from under the fuel and lubricants with a capacity of 200 liters; As an alternative material, you can use a steel pipe corresponding to the drawing of the diameter or an empty gas cylinder with a capacity of 50 to 100 l; You can also use sheet steel with a thickness of 3 mm;
• For the manufacture of the air supply channel, a pipe with a diameter of at least 50 mm is required;
• For a chimney, a pipe segment with a diameter of 100 mm is required;
• a steel channel or a piece of corner with a shelf width of 55–65 mm;
• The air distributor will require a metal sheet of at least 3-5 mm, a slightly larger than the circumference of the case;
• For the manufacture of the cover, a steel sheet with a thickness of at least 3-5 mm is required;
• metal loops for the door;
• If the furnace body is equipped with a water circuit, then sheet steel and two threaded pipe will be required.

The following tools are necessary for the construction of such a furnace:

• welding machine, electrodes;
• Bulgarian;
• file;
• electric drill;
• Metal of various diameters (including coronal);
• hammer;
• an anvil or another stable hard surface;
• yardstick;
• building level;
• pencil.

Calculation of the main parameters

You can improvise a long-burning solid-fuel furnace by using a used gas cylinder, a section of a large steel pipe, or a metal barrel. It is recommended to choose a material whose wall thickness is at least 5 mm. The reason for this is that the case’s reduced thickness will eventually burn out.

The size of the furnace

You can do all the calculations on your own if there are no plans or drawings for the furnace’s construction.

Computation of the Bubafonia furnace’s parameter

In this instance, it will be more accurate to discuss its height (h) and diameter (D). The ideal ratio is thought to be between 1: 3 and 1: 5, therefore these numbers should be proportionate to one another. Since this factor directly affects how long the unit lasts, the furnace’s height is typically made to be at least 100 cm. Making the structure too high is not worth it, though, as loading it with firewood will be inconvenient. It may also have a detrimental effect on the traction’s strength. It may drop to the point where the furnace chamber’s supported flame extinguishes.

Numerous thermal studies have demonstrated that you should not build a stove with a small diameter. Air will only reach a chimney from this small unit, which is why the furnace power will drop dramatically.

The fuel will not burn evenly near the chamber’s interior walls or in the center of the hearth if the furnace’s frame is made too wide. Only the middle portion of the furnace material will burn out in this scenario. The piston’s metal circle will pass through and clog the hearth, extinguishing the flame. This design’s ideal diameter ranges from 300 to 900 mm.

The thickness of the material used

This requirement needs to be considered because the case’s thin walls will eventually burn out. In this sense, choosing a material with a minimum thickness of 5 mm is required. This is particularly crucial if the frame is going to be outfitted with a water shirt, converting it into a boiler. A conditional sign (δ) in the image indicates the thickness of the wall.

It’s possible that the furnace will lose power if you use material with wall thicknesses of only 4-5 mm. The temperature over the piston’s pancake will decrease because of the thin walls of the case. Consequently, there will be less pyrolysis gas burning out, which will lead to less heat being released.

However, the thickness of such a material is quite acceptable for heating small rooms, like a shed, small workshop, or garage.

Parameters of a metal pancake

The thickness of the round plate on the piston is just as vital to the furnace’s efficient functioning as its diameter. Ultimately, a metal pancake functions as both a heating surface for pyrolysis gas ignition and a partition.

When making a metal pancake, you should follow the ideal dimensions. Its outer edge should be five percent of the furnace’s inner wall. This gap is represented in the image by the formula C = 5%D.

The metal pancake’s diameter ought to be marginally less than the furnace body’s interior diameter.

The parameters of the output pipe

The letter S in the image stands for the diameter of the chimney pipe. It is advised that its diameter be at least 80 mm.

The dimensions of the pipe supplying air

The letter D on the diagram stands for its diameter. A pipe measuring 75 or 80 mm can be used in the construction of such a furnace. It is necessary to weld the pipe to the metal circle (in its center hole). You thus obtain a component known as the piston.

Bubophony is an additional choice for a long-burning furnace. You can find a detailed explanation of the installation process, material calculations, and work principle in our article at https:// aqua-rmnt.COM/Otoplenie/Bubafonya-Svoimi-Rukami.HTML.

Preparatory work and choosing a stove installation site

Should the furnace be constructed from sheet steel, it must be cut into the workpieces in line with the drawing:

• From the corners, cut the same fragments that will serve as a grate;
• For the manufacture of stands and handles for the housing, you can also use metal corners;
• It is also necessary to cut the nozzles in advance.

The location of a long-burning oven installation is chosen under the restriction that, in its assembled state, it not be placed any closer to the wall than 100 cm.

The insulating material needs to be considered ahead of time because the furnace body will be fully heated. You can accomplish this by constructing a brick stand that is 30 cm higher than the case’s base. Welding steel corners or rods to the furnace frame is one option.

It is required to lay the insulating material at the installation site from the side of the door to the combustion chamber. Therefore, apply a layer of basalt or asbestos, followed by a 100 cm-square steel sheet.

Finishing the walls adjacent to the furnace with insulating material is required.

Brick and metal are the most frequently used materials in the construction of furnaces with extended burn times.

Making the Bubafonia furnace from a gas cylinder

The ideal used gas cylinder for the self-manufacture of the Bubafonia furnace is one with a volume of 50 liters. The following is the process for carrying out work:

Cut the upper part of the cylinder at the place of rounding of the body using a grinder. This fragment will serve as a lid in the future design.

It is practical to use the cylinder’s upper portion as a cover.

Corners can be used on the piston in place of channels.

Production of a long burning furnace from brick

Of course, a brick stove appears more advantageous when compared to a homemade metal structure. Its independent manufacturing, however, is a time-consuming and skill-intensive process.

Over the furnace chamber is a cooking hob.

Preparation of the foundation

Given the size of brick masonry, the furnace must require a sturdy foundation. The foundation’s depth should guarantee the structure’s stability. The following is how the foundation is being prepared:

1. First you need to dig a small pit 30 cm deep. Its width and length should be 10 cm larger than the alleged dimensions of the furnace.
2. The bottom of the pit is to be filled and covered with roofing material or other isolation material.
3. Pour a layer of sand with a thickness of 10 cm on top, which must be tamped.
4. Top the sand pillow pour a layer of small gravels of similar thickness.
5. For the reliability of the base, it can be reinforced with a metal lattice. To do this, use reinforcing rods interconnected by wire. The width of the lattice cells should be no more than 10 cm. The thickness of the rods is selected from 8 to 12 mm.
6. Put the grille in the pit so that it does not touch the bottom. To do this, put the fragments of bricks under the metal frame.
7. Pour the concrete mixture of the brand M-200 or M-250. The concrete must completely cover the metal frame.

The foundation can be strengthened with a metal lattice for dependability.

Greeding brickwork

You can start laying the bricks for a long-burning furnace a few days after the base hardens. The brick needs to be soaked in water for a day before construction can begin. This has to be done to prevent the mixture from becoming too dry due to the bricks placed in the ranks. This is how bricks should be laid:

1. The first and second row must be laid out with continuous layers.
2. A ash will be installed on the second row, so you need to provide a place for the door.
3. On the fifth row, overlapping is installed above the door. Subsequently, the box of drying chamber will be installed in it.
4. The sixth and seventh row are designed to place a grate and installation of a door in a furnace camera.
5. From the eighth to the tenth row, the firebox will be placed. During the masonry of the furnace chamber, it is necessary to use fire -resistant material – chamotum brick. As a gluing substance for masonry, use mixtures based on clay. Ready -made mixtures intended for laying furnaces go on sale.
6. The eleventh row performs the function of the ceiling of the furnace chamber and forms the area for the chimney. On top of this row it is necessary to lay steel reinforcement and pour it with a cement mixture.
7. A place for the hob is formed on the twelfth row.
8. Starting from the thirteenth – fourteenth row, rows for the chimney are laid. Its height is made according to individual projects, so the number of rows can be increased several times.

How to modernize a long burning oven yourself

A homemade stove can be made better so that it causes less problems.

Modernization of the Bubafonia oven

The Bubafonia furnaces typically weigh between 150 and 170 kg. This is inconvenient because it needs to be turned over in order to clean from ash and other burning residue. You can strengthen the structure by creating holes where the doors are to prevent this. It should be highlighted, though, that the unique feature of this type of furnace lies in the lack of additional fissures that allow air to pass through. As a result, complete sealing of doors in the closed position will be necessary during their manufacture. Welding metal sides and seals to the body will accomplish this.

If you alter the number and form of ribs on a round plate of the piston structure, the air thrust in the furnace chamber will increase. To accomplish this, weld steel plates in place of channel segments. In this instance, they have to have a slight bend running the whole length of the component. The uniformly distributed air flow within the furnace chamber can be twisted thanks to this shape. It takes between six and eight plates to achieve the desired result.

The piston’s curved rods will aid in increasing traction.

Modernization of the brick furnace

If a brick furnace with a long burning period is positioned in the corner of the room, it will require significantly less space. Because of this design, fewer building materials and corresponding financial outlays will be needed.

A separate damper that allows the furnace to be switched between winter and summer heating modes can be added to the brick version of the long-burning furnace. This damper will assist in keeping heating from becoming overly hot during the fall and spring months when there are no frosts but the air is heavy with moisture.

More damper will improve the comfort of the heated environment.
