Chimneys for fireplaces.
In each person, the fireplace causes associations of heat and comfort, with a pleasant crackling of logs into long winter evenings. It will be possible to enjoy such comfort when a chimney, which is a direct channel, which should not have narrowing in the direction of the chimney, is qualitatively installed. On the chimney channel, combustion products are displayed into the atmosphere. There are no smoke channels in the fireplace, unlike ordinary furnaces.
On the principle of binding to the buildings, fireplace chimneys are:
– suspended, which are attached to roof structures. They can be attached to the walls or overlap;
– nozzle (based on a fireplace);
– walls that are built into the internal partitions or into the walls;
– indigenous, requiring the construction of the foundation for them.
The most common are indigenous chimneys that are installed at the site of installation of the fireplace. The brick design is performed with a thickness of one brick or half -brick, and install it on a separate foundation made in the form of a riser.
But all the same, the most practical and economical are chimneys for fireplaces that are built into the internal walls. Such designs are equipped directly during construction work and do not require the foundation. When arranging wall chimneys, one nuance must be taken into account: with the design of the fireplace, location, dimensions, you need to decide at the initial stage of the construction of the house. Chimneys are built into the outer walls very rarely, since the chimney will cool very quickly, and this leads to the appearance of condensate chimney on the walls.
So that there is good traction in the chimney so that its walls are even and smooth, as well as the walls of the wall impatient for the air mass. For the formation of natural traction, the height of the fireplace should be six meters. The structure must be selected with a round section, as it meets the specified requirements to the surface of the chimney. Когда установлены прямоугольные или квадратные дымоходы, то в самих углах будет появляться турбулентность и завихрения. If the chimney has a knee, then you need to install a tee, since soot and dust will accumulate in such a place.
