Chimney - a device that is used to remove the products of combustion.From the design of the furnace member, boiler or fireplace will depend on its effective operation and safety of the operation.
to all types of chimneys, regardless of the cost and type of materials used must meet the same requirements:
- resistance to high temperatures;
- corrosion resistance;
- mechanical strength at high temperatures;
- durability;
- ease of installation.
This is an incomplete list of the requirements for chimneys.All of them are described in the specific regulations SNIP 41-01-2003.He stands as follows: "Heating, ventilation and air-conditioning."
Species
total there are several types of devices:
- chimney classic;
- modular chimney.
Classic version was made of masonry.It is constructed in the last step, after or before laying roofing material.To install it requires the involvement of specialists in the field of masonry brick.When using low-quality material he quickly goes down.
modular chimney - a modern design, the creation of which used the latest materials.It is installed at any stage of construction, it satisfies all Russian construction standards.It is made of the following materials:
- carbon steel;
- stainless steel;
- ceramic material.
When installing the module does not require a chimney specialists and the use of specific tools.The design does not spoil the facade.
single-circuit steel products
a modular chimney is made from thick-walled or thin-walled steel and is the cheapest in its class.It has a polished outer wall, which fits well into the interior.
This type of chimney is used only inside the building.Due to its rapid cooling, the formation of condensate, which upon reaction with carbon dioxide forms a harmful substance having a bad influence on the people and the product itself.Thick modular chimneys have a limited life, and have a thin-walled varieties it even less.
Steel combi versions
opportunities for outdoor use metal chimneys design radically changed by adding heat-insulating gap.To do this, use the two metal tubes of different diameters are inserted in each other.The space between them is filled with mineral wool.This allows for a long time to maintain a high temperature inside the chimney, do not overheat the outer loop.Thus, unless the condition of condensation.However, due to poor corrosion resistance of the life of a chimney module is limited.This causes its low popularity.
Dual Modular stainless steel flues
Structurally similar to a modular system dual-circuit steel chimney.Stainless steel has a tremendous physical properties.In comparison with conventional metal it has a lower specific weight, improved corrosion resistance, is not affected by the sulfuric acid.The only drawback of this design - the cost.However, if you compare the service life counterparts, it turns out that he is several times smaller, and therefore the overall cost of a cheap chimney as a result will be higher.
Chimneys modular ceramic
They are made of a special composition of clay, thermally treated.Yet they are called fireclay ceramic pipes.Weight design relatively small.The outer walls have different shapes and patterns, durable, but require some care.When heated, do not emit harmful substances.
device for ease of installation, modular chimney systems provide a variety of molded parts, which minimizes costs.Consider the basic elements of the modular system:
- Straight section - the main elements.They are made of different lengths (1.5 to 0.5 meters).Interconnected joint to joint.
- Tee - to change the route at a right angle with the possibility of cleaning the chimney.To do this, on the one hand is placed untapped plug - glass.He seals the entire system, preventing the ingress of smoke into the room.When it is time for preventive maintenance of the chimney, the glass can be easily removed, the result is access to clean the chimney.
- Knee - to change the track at an angle of 45 degrees.In the case where the route passes along the way of the chimney there is an obstacle, this item allows you to move away from the straight path and to circumvent the difficulty.
- -through component - serves for the passage of the flue between the beams.This device allows to pass safely between combustible floors, for example, if you have a wooden floor between the first and second floors.Its installation is dictated by the building and fire codes.There are elements with different angles of inclination of the insulating plates.When mounting to exclude them in dock-through component.
- Roof pass element - is used to seal the exit of the chimney through the roof.Structurally similar to the entrance, but has in its structure insulating seal for waterproofing penetration.Insulating material suitable for most types of roofs with different inclination angles.When this element is necessary to pay attention to this fact.All necessary clamps and isolation pads are supplied.
- Wall bracket - for securing the chimney on the outside front wall of the house.Withstands wind loads, is painted in a silver color or hot dip galvanized execution.Each manufacturer distance between the attachment of different, you should consult with the seller.
important procedures
Installation of modular chimney produced from the oven and move upwards.All elements are hermetically joined together.No special tools, welding, soldering.The connection is of special pressed into the grooves.The only serious obstacle may arise at the intersection of walls.
modular chimney is attached to the support surface with special brackets that are interconnected by tightening bolts.All the work is not time consuming and requires expertise.After the installation will need to remove the protective film from the outer shell of the chimney, which protects against premature scratching mirror surface.
