Ceramic chimneys : the device features and installation

Chimney - one of the most important parts of the space heating system under which as a heat source used boilers for solid, liquid and gaseous fuels.However, it is worth noting that some of the models of modern boilers, particularly gas, are equipped with a special turbine, which forcibly removes the products of combustion of fuel out of the room.Turbinirovannym models do not need a chimney.Boilers natural draft chimney work without just can not.Proper design of the chimney, just choose the size and materials for its production, as well as full compliance with the mounting technology are the key to the safety of people living in this area.Unfortunately, quite often we hear of cases where the unsatisfactory condition of chimneys causes the death of entire families.Carbon monoxide is odorless, and saturation of the atmosphere in the house it may be time to miss, especially if you happen to crash at night.On peculiarities of design and installation of chimneys explain further.

Types of installationsprivate houses

Chimneys are made of different materials.Let us consider some of the characteristics of these structures.The oldest kind of brick chimneys are mine.Such designs have their advantages and disadvantages.Among the latter can be identified unwieldiness and complexity of installation.It is also not monolithic chimney design promotes settling on its walls layers of soot and dust, which is often the cause of poor traction.Now modern homes often equip prefabricated galvanized steel, ceramic, or asbestos.Last did not spread because of the harmful effects on the human body, and steel structures have a sufficient number of shortcomings.

Ceramic chimneys are among the most high-tech and wear-resistant designs.They have excellent performance characteristics:

• corrosion resistance.In this respect, they are significantly higher than the chimneys of galvanized iron.
• resistant to temperature extremes.
• accumulate properties.Because ceramics from which the data are made chimneys, can retain heat for a long time within its structure, no condensation them.
• low roughness of the inner walls, which eliminates dust and soot deposition on them.This aspect reduces the cost of operation of the chimney.
• mechanical strength.These chimneys are not defeated strain.
• Easy installation of the chimney.
• durability.Ceramic chimneys with proper installation are a few decades, as evidenced by the warranty period for such a system, which is more than 30 years.

However, it is worth noting that this type of chimney has a number of drawbacks:

• Chief among them is their great weight, which requires at its assembly facilities separate foundation.
• also building ceramic chimney is only possible on a strictly vertical axis, different angles and transitions possible.This often becomes an obstacle for the system installation in the already exploited areas without a repair.
• Another negative point is the relatively high price of ceramic chimney, which is sometimes an obstacle to homeowners.However, it is worth noting that all these virtues will pay them a high price, so that the decision to buy a ceramic chimney would be.

device ceramic chimney

Standard ceramic block, when viewed in cross-section consists of three main parts:

1. Dialling vertical pipe.It consists of a number of special ceramic sections that are joined together.
2. Ball housing or shaft.The outer shell of the chimney.Designed to support the whole structure.As a rule, made of special foam concrete blocks.
3. insulation.A layer of insulation is placed between the tube and the bearing housing, which allows to level temperature differences to avoid condensation formed inside the casing.The basalt wool is used as thermal insulation material, which is a fireproof material.

Height ceramic chimney can be divided into three parts:

1. Base.
2. Receiver part.
3. headroom.

well head is the part of the ceramic chimney, which goes to the roof.It is established a security element generally cone, in order to protect the inside of the chimney from falling precipitation and wind gusts that can reduce the thrust in the pipe.A similar design is available in many plants, for example, ceramic chimney Effe2.

The most intense part of the ceramic elements of the modular chimney - base.It was there that the condensate trap is located, Audit window through which the works on cleaning and prevention systems, ventilation window, which serves as the air inflow into the chimney, as well as a tee to connect the output of the heater.

Ceramic chimneys: Sizes

Data design characteristics are:

• diameter ceramic pipes for chimney.
• height of the chimney.
• height of the head.

Important recommendations:

• flue The diameter is specified in the specification to the heater and must be strictly observed, as it may affect the safety of the people inside.
• In terms of the height of ceramic systems, and are required other than those of brick or metal chimney.The height of the pipe from the furnace grate to tip edge must be at least 5 meters.
• Particular attention should be given to the height of the head.For pitched roof on this parameter affects the distance from the axis of the chimney to the top of the ridge.When the value of this parameter up to 1.5 m height of the tip above the top of the ridge must be at least 0.5 m.
• If the distance from the vertical axis of the ridge to the axis of the chimney over 1.5 m but less than 3 m height of the tip should not beless than the height of the ridge.
• If the spacing of more than 3 m, the angle between a line drawn between the tops of the ridge and the chimney, and a horizontal line drawn through the top of the chimney should be no more than 10⁰.
• When the flat roof structure tip height of the chimney should be at least 1.2 m.

In case of violation of these quantities, the thrust in the chimney may be insufficient for normal fuel combustion.

Also, do not do the chimney is too high because of the opposite effect can be achieved.At high altitude pipe it can create aerodynamic drag that would be an obstacle for the exit gases.

features and technology of installation of ceramic chimneys

Order of installation works:

1. First of all, as we have said, you need to build a foundation.We need it in order to support the weight of all the elements of the chimney.If the floor in a house or apartment concrete, the foundation is not necessary.
2. Once he is ready, the waterproofing layer is laid on him.As a final perfect roofing material or rubemast.
3. on waterproofing is lined with expanded clay-concrete block, which is placed inside the ceramic cup to collect the condensate.The glass is fixed with a solution.Ingredients cook a standard concrete and sand in a ratio of 1: 3.
4. Typically, providers of such systems deliver a set of ceramic chimneys Schiedel, which includes all the elements.This constructor is selected by experts in the manufacturer depending on the configuration of the heater and the room in which it will be installed.All that remains - to collect it properly.
5. to connect the blocks together using fittings.In the corners of the data elements are arranged through holes.If you install them on each other fittings inserted into the holes so that has passed through the 2 blocks.Then the holes are filled with concrete.When laying element solution is applied between them.
6. So, we have laid the first block with a glass of condensate inside.On it lay a metal grate that prevents debris from entering the collection of condensate.
7. Then take the next block and saw off one side of it.Inside it, we will be installing a ventilation grille.Put the cut side of the unit under 90⁰ the future entry of the heater.Likewise, we place a ceramic tee.
8. between the ceramic element and the unit set basalt wool.Next pipe section is mounted with the next block.Ceramic elements are connected to each other by special sealant that prevents leakage of the connection point.
9. The next step is installing the tee under the boiler.Be careful when installing the boiler outlet coincided exactly with the hole in the chimney.Otherwise likely to leak gas using apparatus.Thus, the chimney is built up to the head.Above also provides for an audit hole.
10. headroom can be finished with decorative brick or stone.In certain cases the lining is carried out using siding, which reduces the cost of operations.At the mouth of the chimney is installed protective cap.

Installing ceramic chimney in an existing shaft is made somewhat differently.This is done from the top down.All the elements are connected to the roof, and with the help of a special device lowered down.On each of the pipe spacer mounted spider.The fact that modern systems are equipped with blocks of standard sizes for the diameter of the ceramic tube.If the mine is more, it will keep the spider in the middle of the pipe.

Care chimneys

As we have said, these structures do not require special care.However, experts recommend at least twice a year to check the chimney for tightness and quality of the draft.Also, at least once every two years, or earlier, if necessary, to clean the inner surface of the ceramic tube from dust and soot.
