Why is the chimney clogged?
Chimney clogging is a natural process resulting from combustion. Only part of the fuel, decaying into fractions, acquires a gaseous form and leaves, as an emission, into the atmosphere.
Other fragments with a heavier, denser structure take the form of soot deposits and settle on the inner surface of the pipeline, with time worsening its throughput many times.
The use of firewood from coniferous trees provokes channel blockages.The viscous resinous substances contained in excess in the composition form a powerful adhesive base and contribute to the retention of soot deposits on it.
Such contamination is difficult to prepare for cleaning and requires careful removal by means of mechanical devices.
Household garbage, packaging, remnants of old furniture, textiles and other items that are not a fuel resource, by definition, emit caustic ether complexes, heavy carcinogens and resinous compounds during combustion.
Therefore, the burning in the furnace or fireplace of such human waste negatively affects the operation of heating equipment of any class.
All of them in the form of a dense, viscous precipitate cover the inner surface of the pipes and create conditions for holding soot, soot and soot. The channel through which the gaseous elements escape into the atmosphere narrows to a minimum, the draft throws over, and part of the smoke enters the living room.
The temperature in the room drops, and the use of heating equipment becomes dangerous due to the risk of carbon monoxide poisoning.
They accelerate the clogging of the chimney canal with deposits of firewood from a recently sawn, damp forest.
If the current moisture content of the log exceeds 12%, it is strictly forbidden to throw it into the furnace immediately. It must be thoroughly dried in a warm room for at least 1 week.
Damp logs reduce the heat transfer by 35%, contribute to the rapid clogging of the smoke exhaust system, and eventually disable it.
Sometimes an active accumulation of carbon deposits inside the pipe provokes errors that were accidentally or inexperienced during the laying of the furnace and chimney furnishings for a fireplace or stove.
It could be:
- incorrectly calculated pipe angle;
- too thin walls of the outlet system;
- incorrectly selected chimney pipe;
- increased volume of condensate resulting from insufficient thermal insulation;
- excessive number of bends and turns of the chimney;
- roughness on the inner surface of the drainage channels.
It is these reasons that accelerate the pollution of chimneys and several times reduce the efficiency of stoves, boilers and fireplaces. Homeowners are advised to be very careful about the choice of stove-makers and apply only to those who have already confirmed their skills and high qualifications.
Otherwise, with enviable regularity, the question will arise about how to clean your home chimney, giving you a lot of trouble and requiring constant financial costs.
Symptoms of chimney clogging
It is not difficult to guess about the clogging of the chimney system. This is clearly indicated by the drastically reduced draft in the furnace and a noticeable cooling in the rooms.
Problematic primary ignition of the fuel resource and arbitrary attenuation of the flame also indicates a decrease in the passability of the channels and a violation of proper air exchange.
A signal that the chimney needs cleaning is the changed shade of the flame in the combustion chamber. Fire, in the process of burning acquiring a juicy orange color, clearly implies the presence of a problem.
This is also indicated by an unexpected smell, uncharacteristic of the normal operation of the furnace.
Frequency of cleaning
For preventive purposes, experts strongly recommend that an inspection and a visual inspection of furnaces, solid fuel boilers, fireplaces and chimneys.
Schedule of planned revisions:
- any heating equipment - after the initial installation in a residential building, immediately before start-up, at the end of repair work;
- seasonal operation systems - before starting and at the end of intensive operation;
- gas boilers and stoves - twice a year in the first 2 years after installation / installation, then 1 time annually;
- brick chimneys - quarterly;
- chimneys from any other materials - every 12 months;
- branch pipes of heating and cooking stoves - three times a season.
If problems are identified during the inspection process, they must be rectified immediately. Then the system will function correctly and provide the proper level of comfort and fire safety in residential premises.
Treatment activities can be organized independently or use the services of a chimney sweep. The main thing is to timely eliminate all problems and provide the equipment with the opportunity to work in normal mode.
TOP 5 cleaning products
Chemicals for scheduled cleaning of chimneys of solid fuel boilers, stoves and fireplaces attract with their simplicity, reasonable cost and ease of use.
Owners do not have to purchase special equipment, get their hands dirty and make serious physical efforts to return the equipment to working capacity.
Acquired drugs are simply poured into the fire in a certain volume or stacked with firewood during kindling. In the process of thermal exposure, the working components react with soot or resinous elements and contribute to their decomposition.
The gaseous part, together with the smoke, enters the atmosphere, and the dry part simply crumbles to the bottom. Then it is removed along with solid combustion products and ash.
Many domestic and European companies are engaged in the production of cleaning chemicals. Their products are in stable demand and copes well with the tasks.
Remedy # 1 - Sadpal Cleaning Powder
Polish remedy Sandpal - It is non-explosive and non-flammable fine-grained green powder.
It consists of a complex of inorganic salts and serves as a catalyst for the afterburning of soot deposited in the chimney part of fireplaces and stoves. Effectively affects organics, decomposing it to water and carbon dioxide.
In a volume of 1 tablespoon, it is poured into a well-heated combustion chamber directly on the smoldering parts of the fuel. If kindling is carried out with a dry resource, the dose is slightly reduced, but for a wet one with a weak, poorly expressed combustion coefficient, it increases by 10-15%.
In the process of soot oxidation, large fractions of the formed substance crumble to the bottom of the combustion chamber, while small fractions, together with flue gases, rise up and go into the exhaust pipe.
Using Sadpal cleaning powder, you can:
- optimize the consumption of coal and firewood;
- reduce the risk of ignition of residual soot deposits;
- reduce sulfur emissions;
- protect metal fragments located in the chimney part from corrosion;
- protect ceramic elements of the system from cracking.
With regular maintenance, the pipe will no longer become clogged with combustion waste, will not suffer from tar deposits and will not require complex and labor-intensive mechanical cleaning.
Remedy # 2 - Hansa Concentrate
Concentrate Hansa manufactured by German proprietary technology at the production facilities of a plant in Lithuania.
It is a fine-grained white-blue powder from a mixture of crystals, packaged in plastic jars with lids or economical high-strength plastic bags.
The individual components act as catalysts and stimulate the decomposition of wood resins into combustible gases. Other elements themselves during the heating process produce gas compounds that destroy the structure of soot, soot and tar deposits.
The adhesion to the surface of the chimney system is weakening and all the excess goes into the atmosphere along with the rest of the emissions. The product is accompanied by detailed instructions explaining how to clean a home chimney of solid fuel stoves and boilers, open and closed fireplace complexes.
In addition to powder, the company produces Chimney sweep log and pellets for the preventive maintenance of heating units operating on granular fuel.
Remedy # 3 - Kominicek chemical composition
A drug Comedian manufactured in the Czech Republic. Designed to remove soot and other combustion products from the chimney that are prone to spontaneous ignition and impair the traction properties of stoves, boilers and fireplaces.
In the process of heating, it reacts with substances deposited on the inside of the pipes and decomposes them.
After servicing, stoves and fireplaces work more efficiently, and fuel consumption is markedly reduced. The possibility of spontaneous combustion of tarry and soot deposits is reduced to zero. The use of heating equipment again becomes safe, convenient and comfortable.
Means # 4 - Smoke products from Ecolays
Patriotic digging Ecolais manufactures products for cleaning chimneys in three versions:
The granular preparation is intended for pellet boilers and furnaces. It is mixed with a medium-grained fuel composition and poured into the furnace compartment.
The boxed version consists of metal salts and activated carbon. External labels are removed from it, put into the furnace, doused with a special liquid and set on fire. The product works for one and a half hours, turns soot into a brittle substance and stimulates its rapid combustion.
Log "Smoke" in shape resembles a neat bar of natural wood. It is laid in the furnace with a batch of firewood and does not give out its presence there.
In the process of heating produces a specific flame color azure. This means that the components have already reacted with deposits and the cleaning is proceeding normally.
Remedy # 5 - Spalsadz Cleansing Powder
Polish catalyst for burning tar and soot deposits Spalsadz available in powder form. It contains inorganic salts. In the process of increasing temperature, it releases components that decompose organic structures into water and carbon dioxide.
With ceramic fragments of the flue system, the drug does not react. After global cleaning, the efficiency of heating appliances increases by 20%.
The use of folk remedies
Opponents of chemicals and modern techniques prefer to clean smoke systems with the good old folk ways. They are more simple, affordable and recognized as the safest.
Natural components work slowly and delicately, but do not cause any damage and do not adversely affect the system and its constituent elements.
Method # 1 - Rock Salt Cleaning
Rock salt is one of the most affordable, cheap and environmentally friendly reagents for removing soot from chimneys. There is no need to specially prepare for cleaning. Just pour a few large handfuls into the wood and light a fire right away.
In the process of fuel burnout, a lot of oxygen is released. It softens the soot on the inner surface of the pipe and reduces its layer.
Part of the carbon deposits escapes into the atmosphere in the form of gas, and the remainder crumbles into the kindling part in the form of a dark powder. Then it can simply be raked out with a metal scoop or removed with a powerful vacuum cleaner.
Method # 2 - potato peel for pipes
Potato peel (peeling) is an easy way to rid the chimney of soot and soot. However, in order to achieve a noticeable effect, you will have to prepare a lot of cleanings - depending on the size of the stove or fireplace from half to a whole bucket.
First they need to be dried to a brittle condition and only then loaded into a well-heated firebox.
In the process of catalysis, bituminous components will gradually burn out, and the result will resemble the effect of chemicals, only in a milder version.
Soot powder will pour into the furnace for a few more days, and then it will stop, and the overall level of efficiency of the system will improve. Periodic burning of potato peelings - excellent prevention of occurrence chimney back draft.
Method # 3 - aspen firewood to remove soot
Blasting a stove or fireplace with aspen wood is a simple and fairly effective cleaning procedure. Its convenience lies in the fact that no additional actions need to be performed. It is enough to place a wood bookmark in the firebox, light a fire and wait for its complete combustion.
As a resource for continuous heat production, aspen firewood is not advisable. They burn out too quickly and, in comparison with other types of wood, give an extremely weak heat transfer.
But, as a cleaning element, they are effective and popular. The chimney in the process of kindling is heated very strongly and is naturally cleaned of growths and deposits.
Features of mechanical cleaning
Mechanical cleaning of chimneys is another effective method of removing accumulated soot, soot and tarry deposits, which reduce the quality of the heating system.
It is carried out in two ways:
Cleaning from above through the roof is carried out only under normal weather conditions and without wind. Necessarily requires experience, physical preparation and compliance with personal safety measures.
The master does all the work, standing on the roof of a residential building. With this option, the dirt does not enter the living quarters, but is extracted outside with the help of special devices.
Bottom cleaning is carried out through the outlet of the furnace. The operation is safe and does not require being on the roof, but after it remains in the rooms a lot of dirt and residual combustion products.
The main machining tool is a wide brush for round pipes or a stiff brush for square pipes.
Work is labor intensive and requires some skill. Many owners prefer not to do it themselves, but are entrusted to a professional chimney sweep.
