Why does the fireplace smoke?

The design of the fireplace often involves an open space (firebox) in which firewood is burning. To ensure effective removal of smoke, the masters complement the system with special exhaust channels (chimney).

But in some cases, gases emitting in the process of burning do not want to move in the right direction, which leads to smoke.

This situation is very undesirable, since the smoke is toxic to humans and it is harmful to be exposed to it.

Types of podmyleny

The process of smoking can occur quite often in many fireplaces. It should be noted that this phenomenon brings immediate harm to the body. Smoke can lead to oxygen starvation of blood cells, which, in turn, is fraught with fainting and possible death. Therefore, fireplaces should be operated only in good condition.

Experts divide podmleniya into several basic types depending on the method of gas penetration into the room:

  1. Reverse thrust. In the channel of the fireplace, a flow of air occurs in the opposite direction, which leads to the penetration of smoke into the premises. The causes of this phenomenon may be several, but often it is a violation of the air exchange system in the chimney.
  2. Tipping over thrust. Often this happens when an inflow of air from another source (window, door, etc.) gets into the room. With such podmleniya often smoke leaks not only through the hole of the furnace, but through the free gap of the fireplace. It can happen, both in the process of kindling, and during the laying of the fuel.

Possible reasons

The smoke from the fireplace is not such a rare phenomenon that can happen with almost any design. The reasons for this phenomenon may be several, but they can be divided into 2 large subgroups:

  1. Construction flaws. Often the main cause of smoke is non-compliance with the rules for the construction of the main parts of the fireplace (not the optimal size of the chimney or ashpit, the wrong ratio of the volume of the firebox and chimney, etc.). This not only reduces cravings, but can also lead to the fact that it can practically be absent.Another reason is the wrong location of the fireplace in the room. It depends on this factor whether other air flows will not influence the movement of smoke in the right direction.
  2. Mechanical obstacles. Often the main reason for the lack of traction is blocked chimney gate. In case of improper operation or maintenance, a lot of soot can form inside the channels, which will impede the movement of gas.

Solution to the problem

Before you begin to eliminate the smoke, you should identify the cause. If it is in the wrong design of the system itself, then you can try to fix it in several simple ways:

  1. When the ratio of the size of the portal fireplace and pipes do not match, then this can be corrected with the help of asbestos-cement strip. Its size should be somewhat larger than the width of the portal. Then the strip is located sequentially at different distances, so that to choose the optimal level of the portal, eliminating smoke. When this point is found, the asbestos cement is simply replaced by a special decorative metal curtain that is attached to the fireplace.
  2. An alternative way to eliminate this phenomenon is to arrange a special metal plate on the smoke tooth, which reduces the cross section of the smoke box.
  3. Forced ventilation. To improve traction, special fans are installed inside the chimney channels, directing the flow in the right direction.

When these measures have not eliminated the cause, you only need to completely redo the fireplace itself.

In such cases, it is necessary to trust only experienced professionals.

High-quality operation of the fireplace also depends on the fuel. It is undesirable to use wet firewood, as water not only takes heat energy, but also promotes the formation of soot in the chimney channel. Also, you should not constantly drown pine or spruce, which leads to a similar effect. The best option is a periodic change of tree species (oak, aspen, pine, etc.).

How to melt a fireplace

The operation of such systems involves the manual kindling of firewood. For such purposes, you will need dry wood chips and logs to fit your firebox. To properly melt the fireplace, you need to perform several simple operations:

  1. First of all, you need to make sure that the chimney is not clogged, and the damper is open. This will form optimal traction. It is also advisable to close all windows so that the air does not obstruct the upward movement of smoke.
  2. After that, you need to decompose the wood. To the bottom of the firebox, thin twigs or small cods are placed criss-cross. This will ensure optimum air flow. To speed up the burning process, it is advisable to use crumpled paper (not recommended gloss). On top of the thin blades, they already fold medium sized logs. When the construction is ready, you can light firewood and enjoy the crack of fire.

That your fireplace served long and reliably, it is necessary to trust its construction to experts.

It is also important to constantly monitor it and use only high-quality fuel, which brings warmth and comfort to the house.
