What are chimneys for?
The most important task of the chimney insert is to seal the entire chimney and ensure the removal of smoke from the heating system. The liner is, as it were, the heart of the chimney and its only element, which has direct contact with fuel combustion products from the heating boiler. Let us consider in more detail the functions and possibilities of various types of chimney liners. Function of the chimney
As we mentioned in the introduction, the main function of the chimney liner is to ensure the tightness of the smoke gases, which for security reasons cannot enter into direct contact with the chimney. Steel inserts facilitate the inspection of the chimney system and clean the internal part of the chimney, which, of course, affects the durability of the installation. The quality of the chimney provides high fire resistance and prevents any deformation caused by high temperatures or mechanical damage, which provides the patency of the smoke gases removal system. An important function is also protection against moisture and condensate removal outside the chimney.
The main classification of steel chimneys divides them into acid -resistant and heat -resistant. The choice of the correct insert always depends on the type of fuel burned in the heating boiler. The acid -resistant chimneys are used in central heating systems operating on gas and liquid -fuel boilers. When burning gas and fuel oil, smoke gases are formed at lower temperatures than when burning solid fuel, which is accompanied by the formation of sour condensate, which is a potential danger to the chimney. That is why it is necessary to use steel inserts with increased resistance to acids. Damage - check before buying
When going to buy an insert, be sure to specify the size of the smoke -line channel lumen. Both the channel section and its route are important - if it is not straight, but bends, you may have to reach for a flexible insert. Round inserts are installed in the chimney channels of the square section, and in rectangular - oval. Districts are connected to the boiler using drives, pipes and special connecting sets. In order to choose the right installation method, you should consult a specialist. Cassino Fairspin
