Reasons for reverse thrust in the oven: how to influence the chimney draft device and environmental factors

When using wood heating, fireplace or furnace systems people are sometimes faced with the fact that the smoke does not go into the pipe, and rushes into the room.

This phenomenon is called reverse thrust. Its causes can be very different.

Why is there a reverse thrust

Any odor of smoke or smoke in a room where there is a wood stove or fireplace, should alert the owners.

IMPORTANT! The appearance of smoke in the room is always life-threatening and requires urgent solutions.

Not only is that bad smell causes discomfort and soot stains the ceilings and stuff. Carbon monoxide is also not safe for health.

If you see or smell that the stove start to smoke, you need to look for the reasons for this and fix them. We understand, because of what occurs in the chimney reverse thrust.

Effect chimney structure

Apparatus flues in the fireplace, stove or furnace Russian-Swede done by varying the circuit. If the design was carried out with violations, the owners of the house have to deal with this unpleasant phenomenon.

• Backdraft can still occur to remove pipe blockagess soot;
• At too low relative to the roof ridge pipe smoke may enter the room.
• The lack of a chimney cap becomes another reason.

If the furnace is clogged, the persistent smell of smoke will appear when igniting, when you open the door, when closing the ash.

Such symptoms indicate exactly on clogged with soot or chimney in its construction errors (if there is smoke in the new furnace).

Effect of ventilation

Good traction impossible without proper air circulation in the furnace. For ventilation control in ovens have special valve on the pipe and furnace door-blower. If the ignition furnace suddenly came back draft or not at all, the smoke comes into the room. In such cases, the first step is to check whether the valve is open and the ash pit.

IMPORTANT! To enhance the air flow must also be correctly place the tube on the roof. If the top edge is situated below the ridge of the roof at home, then the emergence of reverse thrust is inevitable.

natural factors

In areas where the cold time of year is often a strong wind and drifting snow, reverse thrust may occur during sudden gusts.

To eliminate this problem requires special crowns and caps on the chimney. They will help ease the wind, and it will not blow the smoke back into the room.

It often happens that we have to heat their home from the night dampness or "uninhabited spirit." If you do it during the day, then the temperature outside is higher than in the house. At this occurrence the reverse thrust becomes commonplace. As the heating furnace and the flue normal air circulation is restored.

Condition of the chimney and operating features

As mentioned above, accumulation of soot in the chimneys reduces the traction and the appearance of smoke in the house.

Experienced potters are advised always to kindle the stove at full throttle and podduvalom. As the warm chimney soot burns and turns into ashes. Then he goes up in smoke on the street.

The importance of removing the reverse thrust

What is so dangerous to the emergence of reverse thrust in the oven?

First of all, the fact that Carbon monoxide can cause death. Its atoms are replaced with atoms of oxygen in the blood and cause asphyxia or severe poisoning of the whole organism.

Do not risk the lives of their loved ones. Better at the slightest problem with the stove you need to consult a professional. They will clean the chimney, fix flaws in the design. And also advise on how to properly handle the fireplace or stove.

Trouble is easier to prevent than to suffer.
