Modern chimneys - a complex engineering structure, on which depends not only the efficiency of the boiler, furnace, fireplace, fuel quantity, but also the safety of the operation of the whole system.Proper selection and installation will not be allowed to appear the reverse thrust, smoke or fire.Therefore, the selection of materials and components, as well as to the process of mounting dymovyvodyaschey system should be taken seriously.It is better to seek advice from competent specialists.
shapes, sizes and types
Chimney - is a vertical channel necessary for the formation of thrust and withdrawal of domestic gas to the atmosphere.Its cross section may be circular, oval or square.The most common form - cylindrical.This demand stems from the fact that it contains no corners which are a kind of barriers to the passage of smoke and fumes, leading to the formation of soot and its settling on the walls.The circular section of the pipe provides a quick and virtually unimpeded discharge of smoke upward.
diameter of the chimney determined on the basis of information from the operating instructions for the heating system.Also it can make expert by calculating the ratio of power boiler, the height of the surrounding buildings and constructions, particularly if these structures are much higher than a building, where the planned installation chimney and the whole heating system.
Chimneys are made of different materials, which determine their appearance.Here are some of them:
1. Plastic.
2. Ceramic.
3. Brick asbestos.
4. From fireclay.
5. Steel.
Features
Before you mount a chimney, you need to make sure that it is properly functioning, ie, provide the necessary thrust, was fitted with a well-insulated, had no difficulty in the operation satisfies all the requirements of fire safety, it has been durable andthat is important, it had sufficiently attractive and aesthetic appearance.
Chimney has the following qualities and characteristics:
- Excellent aerodynamic properties that ensure proper air movement, together with the products of combustion.
- Ideal smooth inner surface.Due to the deposition of plaque on the sooty walls is minimized, respectively, to clean design will need less.
- Proper opposition to the negative effect of condensation and corrosive acids.
- High corrosion resistance.
Installation of brick chimney
Traditionally installation of the chimney is made of brick.But with modern fuel - gas or fuel oil, and transients heating systems exposed brick chimney permanent damage.They are associated with the formation of condensation, which leads to the appearance of microscopic cracks, which absorb moisture into the living room.The service life of such a facility on average is about 7 years.More durable brick chimney - with inner tube of refractory clay, otherwise it is called fireclay.It is the most resistant to fluctuations in temperature.
installation Features:
- It is impossible to deduce the chimney 2 furnaces.
- The distance from the grate to the mouth of the pipe should be more than 5 meters.
- Do not use ventilation channels under the device chimney.
- Equipped valves must have an opening of at least 1.5 * 1.5 cm.
- It is better to spread the chimney with the following dimensions: 14 * 14 cm (for the furnace with a capacity of not more than 3.5 kW), 14 * 20 cm14 * 27 cm (for a furnace with a capacity of 5.2 kW).
- If the exterior walls are made of non-combustible materials, it is possible to arrange them inside the chimney.
For a small furnace masonry bricks made in 4, and for larger power -to 5-6.
Mount ceramic chimney
ceramics used to make chimneys have long, but modern setting fireclay do not look like fire clay pipes from the past years.The thickness of the current ceramic aggregates - no more than 1.5-2 cm. Accordingly, it reduces the weight of the entire structure, and assembling of the chimney from individual modules was easier to process.
units ceramics have high thermal stability and resistance to aggressive environments and exposure to condensation.Despite the fact that they quickly warmed up, chimneys are very fire resistant.They are able to withstand up to 1.5 hours of direct fire.
Ceramic pipes can be found at the insulated chimney with an outer contour of concrete, stainless steel or expanded clay.These systems are modular ceramic, so to carry out installation of the chimney with his own hands is not difficult, the main thing - to observe the necessary rules and regulations.
Features Mounting:
- Installation should start from the base of the chimney, moving upwards.
- On top of the base of the prepared grout put a special module with a tap for condensate.
- Next, a ceramic connecting tee, then - straight elements.All treated with a solution of acid resistant.
- Joints modules must not be connected with the floor slabs.All seams are required to miss the mark with a sponge and remove any excess mixture.
- Ceramic pipes is better to attach a collar every 1,5 m.
work with products from plastic
chimneys made of plastic are lightweight and low cost.They are resistant to corrosion, have the shape of a flexible and easy to install.But their use is limited.Thus, they can be used in applications where the temperature in the condensing boiler reaches only 120 degrees.Technology installation following:
- Pipes cut to the size of pre-prepared.
- With Shaft couplings parts of structure are interconnected.
Despite the fact that this method of mounting is the simplest of all, in the construction sector it is not in great demand.Therefore, the selection of parts and components is limited.
Differences in single- and dual-circuit assembly chimney
Before you carry out the installation of stainless steel chimneys, it is important to become familiar with their types.Chimneys are single- and double-contour warmed.The first is used indoors, the wall thickness shall not be less than 0.5 mm and withstand temperatures up to 500 degrees.In the lower part of the structure during assembly to establish special device assembly condensate.They can be used in rooms equipped with any heating systems.Also, installation of gas produce chimneys for boilers and other units with a temperature of gas does not exceed 500 degrees Celsius.
chimneys Double-circuit ("sandwich") are used both outside and indoors.They are composed of outer and inner loop is between the insulation, such as ceramic fiber or basalt wool.Insulation must withstand temperatures up to 500 degrees without losing its protective properties and releasing harmful toxic substances, has low thermal conductivity.The thickness of the protective layer depends on climatic conditions and ranges from 30 to 100 mm.You can make the installation of the chimney ("sandwich") with your hands.To do this, connect all the structural elements in the correct order with all the features that will be discussed below.
design requirements when installed
heating equipment on the market a wide range of boilers, furnaces, fireplaces, which is not only a traditional solid fuel.Often there are liquid fuel and gas units.Installing this equipment requires the fulfillment of certain requirements.Consider the conditions under which the installation of stainless steel chimney or any other:
1. Chimney channel should completely withdraw the products of combustion.
2. For each of the heater or furnace needs its own chimney.
3. Cross-sectional area of the pipe cross-section must comply with dymovyvodyaschego pipe heating system.
4. Dymovyvodyaschie pipe must be made of special steel with high resistance to corrosion.
5. A chimney should be made as straight as possible.They should consist of no more than 3 turns.A radius of curvature must be greater than the radius of the pipe itself.
6. The height of the chimney must not be more than 5 meters.This height will provide the desired resolution and cravings.
importance of the installation of heating units, especially in the case where the installation is carried out in stainless steel chimney, you need to pay special attention, because it affects the efficient operation of all equipment in general.
Construction of the chimney must be carried out by qualified personnel, as they do their work with all the rules and requirements for fire safety, set out in the regulations.They also take into account the existing recommendations of manufacturers as single-walled, double-walled and chimneys.
General rules of installation of the chimney
Installation of heating units, especially in the case where the installation is carried out in stainless steel chimney, you need to pay special attention, because it affects the efficient operation of all equipment in general.
Construction of the chimney must be carried out by qualified personnel as they carry out the work with all the requirements.
conditions that must be followed when installing a chimney
Mounting chimney, produced by their own hands, requires certain rules:
- The chimney must rise above a flat roof to not less than 500 mm.
- The tube should be placed at a distance of 1.5 to 3 meters from the ridge or the parapet.
Mounting the chimney must be carried out from the bottom of the heater upstairs.For the best connection, it is desirable to apply the sealant with a working temperature of 1000 degrees Celsius.
Places to seal pipe joints must be special collars.The connection parts of the channel chimney must exclude any possibility of deflection.Also flues must not come into contact with electrical wiring, gas pipelines and other communications.
Conclusion
chimney to work well, you need not only to set it correctly.For this channel you must take care of, to make it clean before each heating season.It is desirable that the cleaning work performed qualifying workers who know their business.They ensure the correct functioning of the unit and the safety of living in the house.
