Why is the boiler smoking? If you encounter a similar problem, you can not continue to operate. Smoke and soot in the room are unacceptable. First of all, it is dangerous to health. Equipment will quickly fail if you continue to operate in such conditions. Therefore, it is necessary to establish the cause of the appearance of smoke, and then proceed to eliminate it.
What to do if the gas boiler blows out
The first and main reason that the boiler smokes is poor draft in the chimney. This problem is typical for devices with an open combustion chamber, which require connection to a common chimney shaft. To maintain the flame, the technique takes oxygen from the room, so high-quality ventilation is organized.
The draft in the chimney allows the combustion products to be removed during the operation of the boiler. At the same time, it supplies oxygen to the ignition unit. If there is no draft, the burner may go out, carbon monoxide will begin to enter the room.
Why do draft problems occur and smoke does not go up the chimney? There are several reasons:
- Chimney blockage. The mine can become clogged with foreign debris and foliage from the street when blown by the wind. Over time, soot accumulates on its walls, which narrows the passage of the chimney. Another problem: the blockage of the upper part of the pipe. This happens when the hole is blocked by a satellite dish, a lid. In winter, the hole is clogged with snow.
The products of combustion are removed at a high temperature, so condensate settles in the mine. In the cold season, it freezes, forming ice.
- The installed flue type does not match your model. The pipe diameter is too small to effectively remove the fumes. Perhaps the installation was not carried out correctly, slopes and heights were not taken into account in accordance with the standards. If the structure is too low, there will be a pressure mismatch. Therefore, natural traction is not formed. A rarer problem is the installation location. For example, placement on the windward side. Or there is a tall building nearby that blocks the air flow.
- Leaky connections. Make sure pipe joints are tightly sealed.
If the floor-standing boiler “Buderus”, “Baksi”, “Vailant” is located in the boiler room, the ventilation for air flow should be on the same side as the chimney. Otherwise, in windy weather, smoke will enter the room.
- Reverse thrust. This is caused by weather conditions, for example, the blowing of the mine by the wind. Pressure drops also lead to problems.
Trouble-shooting
The presence or absence of traction is immediately checked. Light a match and bring it to the control window of the boiler. If the flame deviates to the side – there is thrust, it burns evenly – no.
To understand what is the cause of the problem, look into the outlet hole with a mirror and a flashlight. So you can check for blockage, accumulation of snow. For your part, you can clear the shaft. And for cleaning from the street, it is better to contact a specialist.
See which chimney will fit your model. Install the product of the correct diameter. Then carbon monoxide will be efficiently discharged. The length of the pipe must comply with the regulations, and be higher than the roof ridge.
To prevent ice from freezing inside, insulate the mine. For self-design, use the sandwich design. She already comes with a heater.
Inspect all connections for cracks, damage, inconsistencies. Press the joints tighter, use a special sealant to isolate cracks. In boiler rooms, open the window, creating natural ventilation.
