It is clear that if the house has a system where fuel burns, then you can not do without a chimney. Very often it is collected from ready -made blocks. This design can be made separately, or attached to the wall — outside the building or inside it. Chines from finished elements can be installed separately or attached to the walls inside or outside the house. Assembly from ready -made modules, to say, is convenient. But the installation technology has its own characteristics.
As a rule, the modular chimney has an internal liner placed in a block, the material for which is light concrete. The liner is usually made of ceramics resistant to acids (they are formed from combustion products). If the chimney is external, then there is also a layer of isolation between the liner and the external unit. There are channels around the insulation that allow it to dry quickly.
For a boiler having a closed combustion chamber, systems from special pipes that are called coaxial (“pipe in the pipe”) are needed. When installing a modular chimney, the finished elements of the internal liner are interconnected by a solution or acid -resistant putty. Then they are wrapped in a layer of insulation, and then laying an external unit is laid-on a cement-lime solution or adhesive mixture. The modular chimney takes less space than brick, its installation goes faster.
