A chimney in a multi -storey building should be of high quality.
The one who has a fireplace in the apartment of a multi -storey building probably faced a situation when smoke does not go outside, but creeps around the room. This situation is associated with the formation of reverse traction in the fireplace, which can occur for various reasons, for example, in the absence of wind or during the rain. But it can be caused by the technical malfunctions of the chimney itself. Therefore, it is especially important that the chimney in the multi -storey building is fulfilled in strict accordance with all the requirements of the norms and standards.
The occurrence of reverse traction can be due to insufficient height of the chimney, a small diameter, a large number of curbs of the chimney for the fireplace and the irregularities of the internal walls, the wrong installation relative to the roof skate, and the presence of high -rise buildings. The absence of supply ventilation in modern apartments of multi -storey buildings also has a great influence, in which, as a rule, metal -plastic windows and doors are installed.
In addition, in the case of a multi -storey building, drafts on the stairs or an open window on the top floor can affect the high -quality work of the chimney. The design of very many modern multi -storey buildings does not allow to mount chimneys at right angles (which is the most optimal option), so you have to perform inclined transitions. And if it is performed at an angle of less than 45 degrees vertically, then the probability of the formation of reverse traction is high. Problems may also arise due to the fact that you have not used fireplace for a long time. So if there was such a place, it is advisable to pre -warm the air in the chimney – burn a little paper in it.
In order to improve traction, a chimney in a multi -storey building can be equipped with a special device that forcibly removes combustion products. The design of this device is quite simple and consists of a turbine and electric drive, which is mounted in the upper part of the chimneine pipe.
But there are other ways to improve the quality of the chimney in a multi -storey building and eliminate the reasons, as a result of which the reverse traction is formed. This is an increase in the diameter of the pipe for the chimney, cleaning it from soot, transferring the chimney, as well as improving the supply ventilation in the apartment. You can also install coaxial chimneys, the design of which involves air fence directly from the atmosphere.
