chimney is an essential part of the design of the fireplace.Its quality depends on the duration and reliability of the fireplace hearth.The main task, which is assigned to the chimney for a fireplace, is considered damaged the output of the combustion products.To ensure stable operation of fireplaces need good traction, enhances the process of combustion.To all the structural elements that draw the smoke from the furnace to the chimney and into the atmosphere are increased requirements for fire safety.This is especially true in wooden houses.In addition to the chimney should be easy to repair, and periodic cleaning of its soot.Not the last role played by the cost of the device chimney, which affects the value of the material, the place of manufacture, as well as the complexity of the installation.
Design - a condition work perfectly ↑
When designingFireplaces focuses on the choice of optimal design and location of the chimney.This will determine the correct air circulation.It is best to lay the device chimney for a fireplace in a house project in advance, ie before the start of construction of the facility.It lets you choose a fireplace and a chimney to plan its design, according to the financial possibilities of the owner of the house.
If the house has already been purchased off the shelf, and it laid the chimney, selecting fireplace consult with specialists who conduct examination facilities for the removal of smoke and give an opinion on its compatibility with the chosen model of the fireplace.
There are also technology and facilities installation of a fireplace chimney in the finished building, of which the experts choose the most safe for a particular property.
Important!It is advisable to place the chimney close to the ridge, and in the warm part of the house.Otherwise, take action on warming the walls of the structure to prevent freezing flue.Otherwise, it will be bad rastaplivatsya fire and smoke due to the deterioration of traction.In a standstill can be a source of cold air and odor.
main types of chimneys ↑
Currently, there are many designs of fireplace chimneys, among which we can find a device that is suitable for any country house.For the manufacture of flues used brick, concrete, ceramics, metal and even glass.This variety of materials allows to develop different designs for decorating the room with a fireplace.Classic brick
This type of device flue used since time immemorial.It requires a high level of professionalism from the stove-maker, who is able to perform a quality installation of the chimney to the fireplace in the form of a brick shaft.Proper facility design will allow it to serve for many years.Services specialist of this level are quite expensive.But the available materials necessary for the construction of the brick mine: burnt bricks, sand, clay and water.We must remember that this building requires a solid foundation.Chimney brick built into the wall at the time of construction.
Combined chimney brick and steel pipe ↑
Very often, brick mine, standing apart from the wall or built into them, complemented by a sealed thin-walled flue pipe (rigid or flexible), made of stainless high-temperature acid-resistant steel.By this technique enables:
- hundred percent leak flue;
- optimum circular shape;
- smoothness of the walls, do not impede access of smoke;
- decrease the thermal load on the brick wall of the shaft, as well as materials of construction and houses, in contact with the outside shaft.
Thus, brick mine becomes a durable enclosure and an excellent thermal insulator chimney made of metal.Thus it is possible to efficiently use the intermediate space between the walls of the mine and the chimney, creating special conditions for air circulation.This increases the heat transfer structures and reduces the temperature level of the outer surfaces of the shaft and a metal pipe, which extends their service life considerably.
Advantages of steel fume collection systems ↑
already built in private homes, the draft of which is not provided by the device chimney, used steel structures, assembled from separate elements - metal pipes.Stainless steel chimneys have a lighter weight compared with brick mines, so the devices do not require a separate foundation.Installation does not cause much difficulty, and chimneys are usually suitable for all models of fireplaces.
advantage of metal pipes used to smoke channel device, is the optimal cross-section of the round form, does not prevent the removal of the products of combustion.The square and rectangular channels formed local eddies, which prevent the movement of the stream of smoke.In round pipes the problem does not arise.Smooth wall metal chimneys do not contribute to the accumulation of soot on them, which simplifies servicing facilities during operation.
Currently on the market are the construction of steel chimneys both foreign producers (Selkirk (England), Raab (Germany), FFBofill (Spain), Hild (France)) and domestic companies (Elits, CM Research Institute (Moscow)Baltvent (Kaliningrad), Rosinox (Wedge)).
Important!Domestic production, which has a certificate of quality, is not inferior to foreign analogs, while its cost is much lower.
Insulation - Increase heat ↑
All metal chimneys can be divided into two groups:
- insulated pipes - "sandwich";
- «hot pipes" without insulation.
On the use of "hot" pipe in a brick shaft, see above."Sandwich" constructs consist of two pipes laid special fire-resistant insulation layer.The inner tube is made of high quality stainless steel, capable of withstanding high temperatures and aggressive chemicals.
used as thermal insulation incombustible materials with low thermal conductivity and do not emit under heat dangerous to human vapors and gases.Set of different elements of the "sandwich" -trub allows you to mount the correct size for the fireplace chimney.Practices and production of insulated pipes under the order for specific properties.
Apply refractory ceramics ↑
Chimneys made of ceramic fireclay tubes enclosed in a shell made of stainless steel or lightweight concrete, appeared in the domestic market relatively recently.Produce them in Germany under the brand name Shiedel.This German chimney system is a single, ready for installation, the elements, and all other consumables needed to install a vertical chimney.
outer sheath construction elements equipped with ventilation channels that allow to reduce the temperature on the surface of the chimney.They also provide channels for the determination internal mounting, which increases the stability of spaced apart structures.
scheme chimney fire: Shiedel UNI ↑
1. The inner tube, which has a circular shape, made of high-quality fire-resistant fire clay.This material has high density and strength and is resistant to acids.Elements of the inner tube connected to a special fire-resistant putty that seals the flue.
2. To fix the elements of the outer shell, a solution adapted to the cement-sand base.
3. Set chimney systems include:
- Modules for control of the whole structure;
- fasteners to the roof;
- elements connecting the chimney to the fireplace;
- decorative trim headband nadkrovelnoy of the chimney.
Important!These systems are ideal for wooden buildings, because they possess an effective thermal insulation.It can be mounted near combustible constructions houses pyatisantimetrovym space from them.
Spectacular glass chimneys ↑
In today's market there, albeit in limited quantities, and other "exotic" materials for the device chimney.Such materials include glass.The advantages of glass chimneys include:
- resistance to moisture;
- low thermal inertia.
However, these structures are very expensive in itself, as well as their installation is associated with high material costs.Perhaps in the near future glass chimneys will displace other materials from the market.While they account for a very small percentage of sales.
Important!Never use for the installation of the chimney asbestos cement pipes.This material is carcinogenic and fire hazard.

conditions for the normal operation of the chimney ↑
Operation fire will not bring trouble, if during the installation will take into account all the conditions to ensure the normal operation of the chimney.It is necessary to ensure that the rate of promotion for open gas burners and a sufficient vacuum for closed.The height of the chimney flue can not be lower than 5.5 meters, measured from the burning surface.It is important to maintain the relationship between the area and the shape of the cross section of the flue channel, its height and dimensions of the fireplace insert.
Mistakes can spoil the beauty of having a fireplace.He can become a decorative element in the interior, which can not be used for other purposes.Therefore, if the desire to install a fireplace in your home, it is necessary to contact the professionals having a name in this market segment.
