Condensation in the chimney pipe: how to get rid of it so that black liquid does not flow along the walls of the chimney
A chimney is an obligatory part of the furnace. Condensation appears inside the pipe. Moisture is formed during the combustion of any fuel.
Steam is formed, which tends upward and combines with cold air. The result is condensation.
If there is too much moisture, then together with soot they create a tarry black liquid. Sometimes it comes through the masonry, which leads to wetting, stove leaks and an unpleasant odor.
Causes of condensation
- Raw or unsuitable fuel that contains a high percentage of water. It is better to heat the stove with coal and dry birch firewood,
- No pipe insulation
- Problems with traction, fuel does not burn completely,
- Clogged pipes, accumulation of debris, rough pipe walls,
- Temperature difference. The air outside is colder than the steam coming out
- The pipe is too long. In the upper part, the steam will quickly cool and settle in the form of condensate.
How to get rid of condensate in the pipe?
Before the heating season, clean the pipe. You can use a rope with a weight attached. Chemical preparations will help to clean the pipe (for example, the Chimney Sweep tool). There are folk remedies: burning potato peels with salt.
Chimney insulation.
Mineral wool is used for metal or asbestos-cement pipes. It is better to insulate a brick chimney with plaster.
Sleeves are often used - an option for getting rid of condensate. They put a "fresh" pipe in a brick chimney.
No need to take apart and rebuild anything. Everything is done quickly, not expensively and simply. A ceramic, stainless steel, polymer or sandwich pipe insert is installed inside the chimney.
A steel chimney most often suffers from condensation. To solve the problem will help (to choose from) several ways. Replacing the old pipe with a new one (insulated). This is a sandwich system.
You can buy a stainless steel condensate collector. It accumulates accumulated condensate. He is placed on
the lower part of the vertical element of the chimney. Only regularly it will be necessary to clean the container in which the liquid will accumulate. Suitable for gas boilers and stoves.
