Our country is popular solid fuel boilers, furnaces and fireplaces. All of them need chimney, which over time is contaminated, which leads to a deterioration of thrust. But the main danger is to fire soot, because it can cause the destruction of the smoke tube and the fire in the house. We tell how to warn this threat.
Whatever you rinse the oven (boiler, fireplace) - wood, coal or pellets, amorphous dust carbon (soot) and smiling sediments will be accumulated in the smoke tube. It also relates to combustible substances, the temperature of their ignition ranges in the range of 250-400 ° C, and the combustion temperature with intensive oxygen supply reaches 1,000 ° C. The brick tube at the same time can crack or destroy the masonry seams - and the fire will turn into adjacent wooden structures. Steel modular chimney is more resistant to high temperatures, but it is sometimes destroyed during fire, it is sometimes destroyed and almost always loses resistance to condensate - it starts rust faster. To eliminate the heating of the chimney to 250 ° C, as well as the ingress of sparks from the firebox on South, is impossible. Therefore, the only reliable way to prevent trouble is to maintain purity in the pipe. For this, three rules must be followed.
1 Carefully choose fuel
Turn the oven only dry firewood (drying time of the birch birch firewood - at least 3 months). When burning raw fuel, there is little heat, it is distinguished by a significant part of the carbon and settles on the walls of the chimney. The secondary survival chamber in this case is ineffective, since the flue gases are not flammable due to the low temperature in the furnace.
The tree of wood also affects the rate of pollution of the chimney. It is advisable to buy a mixture of birch and aspen, and firing firing and pine wood only as a last resort. When choosing pellets, it is important that they do not publish "chemical" odors. In addition, you can check the fuel quality, immersing several pellets into the water: they must quickly swell and turn into suspension. Store pellets need in a dry room.
You can not burn in the furnace of a regular boiler, a fireplace or stove painted wood, as well as trimming of any building sheets and slabs based on wood fibers, sawdust and chips. The removal of paint, formaldehyde glue and other complex chemical compounds causes harm to the environment and also leads to the formation in the chimney of persistent contaminants.
Elements of a modern modular chimney: 1 - revision trim (cleaning); 2 - a tee for connecting the unit; 3 - stainless steel channel; 4 - casing from GVL or other non-flammable material; 5 - passing node; 6 - Protective Cap (Flugark).
2 Clean the pipe regularly
If you have a wood boiler or oven, which is the main heater, then at least once a year (better at the end of the cold season) need to clean the chimney. With this task, you can cope with yourself, if at the stage of building a house to provide a hatch in the roof or mount a roofing staircase and a platform with railings near the smoke tube. And you can not forget about the safety belt!
Cleaning the brick pipe of the rectangular section is much longer than the round channel made of steel.

When cleaning, I first use a rope weight, which serves to knock down large, partially exhausting soot flakes. After two-three passages with this device take a weighty lubshik (it can be purchased in the construction market or make it yourself), the diameter of which should accurately correspond to the diameter of the chimney.
When cleaning the steel modular chimney, as a rule, it is necessary to dismantle the knee and remove the flugark.

If independent cleaning is impossible, the work is entrusted by a firm specializing in industrial mountaineering, the price of the service varies from 3 to 15 thousand rubles. Depending on the location of the house, diameter and configuration of the pipe, season and other factors.
3 Use chemicals
Snowy winter climbing the roof is difficult and dangerous, so you need to use chemicals. They are produced in the form of powder, granules or briquettes. The composition of the drugs, as a rule, commercial mystery, but almost always includes stearin, urea and copper sulphate. These substances penetrate into the thickness of integral deposits and contribute to their detachment from the chimney walls. Approximately from the middle of the winter and before the end of the heating season, the chemical cleaning agent (50-150 g) should be added to the firebox at least once a week, without forgetting to periodically remove the shred flakes from the drives.
