How to clean the chimney soot: how to properly clean the smoke channel
Heating devices that use wood or other solid fuels require periodic cleaning. Deposits on the walls of the chimney are dangerous not only by narrowing the canals, collapsing and blocking the aisles, but also by igniting the plaque, which can cause a fire in the house.
Timely cleaning of the chimney from soot is a mandatory measure in preparation for the heating season.
Chimney cleaning: chemical or mechanical?
Mechanical cleaning is a rather complicated and time-consuming process. Therefore, as a rule, it is carried out no more than 1-2 times a year. But with intensive use of heating devices, this is often not enough.
In addition, the more deposits are formed on the channel walls, the more the efficiency decreases - the efficiency of fuel use decreases.
Mechanical cleaning of smoke channels
The purpose of mechanical cleaning - getting rid of soot and soot, conducting routine inspection. Even if during the entire heating season, measures were taken to minimize accumulations on the walls of the chimney, all the same, the likelihood of disturbances in the operation of the chimney remains.
If cleaning starts from the chimney section located above the roof covering, care must be taken to ensure safety. To do this, use a safety cable. If there is none, then a rope is tied around the belt, the other end of which is fixed around a reliable support - a chimney or a tree growing on the side opposite to the chimney.
In order to minimize the ingress of soot into the house, and then it will be rather difficult to clean it off, the doors of the firebox and the seat are tightly closed. Fireplace curtain wet cloth.
Before you start work, you need to figure out how to clean the chimney from the bottom, without getting out on the roof. And only if there is no such possibility, they start cleaning, starting from the pipe section on the roof.
If cleaning starts from the roof, then the work is carried out in the following order:
- Putting all the accessories in a bucket, climb to the roof, secure the safety cable.
- If a fungus or deflector is removed from the tube head, if any.
- They clean the smoke channel, trying to remove all deposits - holding the cable, lower and raise the ruff with the weight.
- After the channel is cleaned, put the tools in the bucket, set the deflector in place. Having unbuckled a safety cable, go down.
- In the house or in the attic, clean the doors (sazhtruski) open and remove the crumbled soot.
Continuing to move from the upper channels to the lower ones, they carry out cleaning, after which they choose sprinkled soot and close the doors.
All cleaning procedures are carried out carefully. A newspaper, oilcloth or thick fabric is covered on the floor. Soot that has fallen to the floor, first collected with a vacuum cleaner or a dry broom, a rag. After all collected, wash the surface.
It is better to choose a vacuum cleaner with a plastic container, or to use industrial electrical equipment - they are easier to clean from contamination. There are also models specifically designed for collecting soot and ash.
How to make a ruff do it yourself
In order not to buy a ruff, you can make yourself a device for cleaning the chimney from plastic bottles or a metal cable.Plastic is more versatile and suitable for all types of chimneys. While a metal brush can damage the protective coating of galvanized steel chimneys or tear off the clay layer, which is applied to make the internal surfaces smooth.
For the manufacture of a ruff from a plastic bottle, you need a steel cable with a diameter of about 2 mm, a clamp, two plastic one and a half liter bottles. Bottles are cut in half (across), dissolved in strips, leaving the upper part intact. In the bottoms make holes of small diameter with a heated metal object (wire, screwdriver). The same hole is made in the covers.
The halves are connected to each other, putting on a threaded hook in the following sequence: bottom, neck with lid, neck with lid, bottom. Fix the connection with two nuts and two washers. Then a connector is put on the end of the hook and a threaded rod (rod) of the appropriate diameter is screwed onto it. You can also use plumbing cable for cleaning sewer pipes. The length of the cable may be about 2 m.
To clean the blockage in the chimney, you can use a ruff mounted on a cable, to which a heavy object is attached to the bottom. A metal ball can be used as a weighting agent. Objects with a displaced center of gravity are not desirable, as they can roll over and get stuck in the chimney.
Cleaning with chemicals
Effectively prevent the accumulation of soot in the chimney will help special means. They are intended for prevention and are designed to ensure that their use is regular. These additives are used during the combustion of firewood. As a result, soot is destroyed at the stage of combustion. They are used before mechanically cleaning the chimney, as well as periodically, throughout the heating season.
Use of powder
Powder chemical cleaner is designed to burn sediments formed on the walls of smoke channels, firebox.The tool is combusted with solid fuels and prevents the deposition of soot and tar. The use of a catalyst makes it possible to partially burn soft deposits and loosen hard deposits. The systematic use of the tool allows you to maintain the efficiency of the use of heating systems and furnace devices.
The rate of addition of the powder is about 1-2 kg per ton of fuel or 1-2 tablespoons for every 10 kg. When using firewood from resinous trees, the catalyst is used every third load. The catalyst, which is applied correctly, should give white smoke of a yellowish tint.
Chimney cleaning with chimney log
One of the effective means of combating creosote deposits is a special log. It is absolutely non-toxic product that can be used to clean stoves, fireplaces, wood-fired boilers, and coal.
It is very easy to use logs. To do this, it must be set on fire and left to burn.As it burns, smoke enriched in salt mineral penetrates the creosote, dries out and makes it loose. Thus, it is possible to almost completely clean the walls of the channels from deposits.
Folk remedies to combat the accumulation of soot
The most famous old-fashioned way to combat blockage in chimneys - burning potato peelings. Using them most effectively during intense burning. Under the action of high temperature, steam is formed with a high starch content, which loosens and softens deposits. Soot exfoliates and showered. This method is suitable for the prevention of channel blockage and how to prepare for mechanical cleaning.
Burning aspen wood in large quantities, as a method of cleaning soot from the chimney, although considered effective, can lead to bad consequences. High temperatures that cause soot to ignite in the flue exhaust channels can cause a fire if it has cracks or damage. In addition, not all metal sandwich chimneys can be operated at very high temperatures.
How to reduce chimney pollution
For different types of heating devices, it is common to accumulate soot in smoke channels at different rates. So, the more protrusions, roughness and irregularities, the more soot settles on the walls. It prevents soot from entering the atmosphere and numerous turns or incorrectly laid out smoke channels.
But if the stove, fireplace, boiler is already installed, there is no possibility to change its design. But you can minimize the other negative factors that lead to severe pollution of the chimney.
What fuel is better to choose?
During the combustion of any fuel in the chimney a deposit of soot and soot is formed. But one of its kind can form more sediments than the others. To reduce the intensity of pollution can be, if you use the "right" fuel.
Wood of different tree species has a different chemical composition. Different content of tar, oils, tar, creosote affect the degree of sediment formation on chimney pipes. The less these substances in the wood, the less soot will be formed in the combustion process. Other solid fuels also affect pollution to varying degrees.What kind of fuel forms soot more than others?
- firewood from conifers - spruce, pine;
- birch firewood, which has a high content of tar;
- briquettes or pellet granules from the husks of sunflower seeds due to the high oil content give an intensive formation of soot.
It should also be noted that burning in the kiln of household waste, especially plastic, also contributes to the formation of plaque.
In contrast to these types of fuel, firewood from oak, hornbeam, beech, walnut, sycamore, pear, and apple trees can be noted. These hard rocks cause much less pollution of the smoke channels.
Dependence on humidity and temperature of burning
It is highly desirable to use dry firewood for space heating - the drier the better. The fact is that, when burning wet fuel, the ash under the influence of steam rises with it and sticks together in clumps. It becomes heavier and can not leave the chimney. As a result, it accumulates inside the chimney in the form of soot.
Therefore, they need to be harvested in advance and stored under a canopy, in special indoor premises, sheds. In such conditions it will be possible to reach 15 - 20% humidity.At the same time, the degree of dryness will always fluctuate depending on the humidity of the air in the room, outside.
The amount of soot formation is also affected by the burning temperature. The worse the firewood burns - the greater the degree of pollution. This is due to the fact that at low temperatures an excess of carbon particles is formed, which is deposited in the form of soot and soot. This phenomenon is especially characteristic of the initial burning, when the firewood only inflames.
Therefore, when kindling a stove or a fireplace, you need to strive to increase the temperature in the firebox as quickly as possible - melt the stove with dry firewood, use more thin and dry chips. In addition, after the attenuation of the fire, it is necessary to retain heat. For this, as soon as all fuel burns in the stove, close the gate. And then at the next kindling, the temperature inside the oven will be much higher than if it had not been closed.

How to make a ruff from a plastic bottle and clean the chimney with it:
You can check how you managed to clean the soot from the soot using a newspaper. It is set on fire and brought to the firebox and to the clean door. If there is no thrust at any site, then, most likely, in the channels located above, the blockage could not be removed. In this case, it is better to invite a specialist who will help determine the exact cause and cope with a bad burden.
