Determine the type of chimney, its functions and quality

What are the types of chimney?

Several types of chimneys are of interest in the construction industry, characterized by their individual characteristics. Price, quality, complexity in installation, wear rate, ease of handling - each type has different indicators. In any case, it is necessary to familiarize yourself with certain standards or consult with competent specialists in the construction industry.

These types of chimneys are distinguished:

1. Steel, stainless pipes. In general, galvanized steel is used. Their demand is often proved by steel pipes in that they are not able to react to acidic effects( such pipes are used in areas with high acidity of the atmosphere).This resistance is proved by the presence in the steel pipes of the substance of molybdenum, a microelement, which, thanks to its enzymes, does not react to the action of irritant compounds.

Steel chimneys have the following advantages:

• Hermetic and do not let air, moisture, light;
• Easy to maintain and use;
• High exhaust outside( street);
• No condensation;
• No risk of fire and ignition.

Among the minuses, it should be pointed out that the steel chimneys have sufficient enough cost, to create their projection, the participation of a specialist is often necessary, it is almost always necessary to mount additional insulation, and for this, a sandwich tube is made.

1. Brick. Some of the most relevant and common. Such popularity is often caused by universality, strength and financial accessibility. Sufficient ease in the design allows you to properly mount the chimney.

Brick chimneys can be found in almost any residential building. They are the most popular and have the property of polyfunctionality( the only thing is that they can not be used as a gas communication because of insufficient tightness and the ability of the brick surface to break down when interacting with gas).But, despite such a demand, brick pipes have a number of important nuances:

• Observing the height, namely the length of the pipe that is above the roof;

• You can install a brick chimney only when the thickness of its walls is more than 10 centimeters;
• At a distance of 15 cm from the roof to the chimney, it should not have cracks or joints;
• Smooth cross-section of the pipe channel, which will ensure a uniform smoke extraction;
• The quality of the brick must be suitable for the temperature of the passing air, the strength of its flow and the speed of the passage.

It is important to remember that the slope of the pipe must in no case be more than 30 degrees.

1. Ceramic, which is a very intricate structure made of ceramic, steel or concrete base.

1. Fireclay, glass.

Chamotte - the material is not new in the construction market. It is distinguished by a heavy-duty shell of concrete, steel and internal fullness of ceramics. If we consider the components of such a chimney, it is broken down into parts:

• Kernel - fireclay pipe, often consisting of ceramics, serves as an outlet for combustion and harmful gases for breathing;
• Insulation layer from basalt base;
• Steel or concrete sheath.

Chamotte has its own negative nuances - an overestimate, which is completely compensated by the advantages of these chimneys.

1. Asbestos pipes, asbestos-cement pipes are one of the classic solutions. Easily mounted, but the material is fragile and can not last a period, at least close to steel and brick chimneys.

Other pipe options when deciding how to make the chimney

Chimneys are also divided into:

• nasadnye - chimneys are the most common option;
• indigenous - located separately from the furnace;
• wall - placed inside the walls of the house.

Note: Many construction companies use coaxial chimneys, the basis of the structure of which has nested pipes.

They are extremely rarely used in everyday life, and in vain: such pipes allow you not to install any additional ventilation. The principle of action is to take fresh air from outside by means of an outer tube, and through the inside out gases and combustion products are emitted. They work as follows: the intake of outdoor air is carried out through the outer pipe, and all combustion products are withdrawn through the internal pipe.

General rules for chimneys

In addition to knowledge of the types of chimneys and the requirements for their construction, it is necessary to familiarize yourself with the general rules for how to install a chimney:

1. Chimney outlet should always be directed upwards.
2. Do not use additional chimney coverings.
3. Absolute pipe tightness
4. Excellentdraft speed in the pipe
5. No condensation
6. The design of the chimney must be based on the SNiP position.
