Chimney cleaners: the best way to clean the chimney soot
Careful operation of furnace or boiler equipment is not a guarantee of the absence of soot in the chimney. The question of cleaning the chimney remains constantly relevant. In order to facilitate maintenance, special means are used to clean chimneys and furnaces.
Some are aimed at the prevention of resin deposits, while others are aimed at their destruction. Do not lose relevance folk and mechanical methods of dealing with soot.
Causes and effects of polluted chimney
Combustion is a physico-chemical process, as a result of which combustible substances are oxidized and a large amount of heat is released. Fuel breaks up into fractions - part is converted to gas and rushes up, creating cravings. Particles of unburned materials (plaque and soot) are deposited in the chimney.
The amount of deposits directly depends on the complete combustion of the fuel.With active combustion, the organic content is sharply reduced - water vapor, sulfur dioxide and carbon dioxide come out of the pipe. Heavy tar and ash are deposited in limited quantities.
In addition to natural combustion and smoldering processes, the main causes of chimney clogging include:
- The use of wood with a high content of resinous substances, such as firewood from coniferous trees. The resin forms an excellent adhesive base for adhering soot.
- The firebox of a boiler or stove with poorly dried or freshly chopped firewood - condensate settles on the inner surface of the smoker. Soot particles accumulate faster on wet walls.
- Use a heating device for recycling. Burning household garbage is a complex of esters, tarry components and non-combustible substances that contribute to the rapid pollution of the smoke channel.
- Pipe protection cap. From the side of the street, leaves, birds can fly into the chimney, etc. During the time that the furnace is idle, a wasp or bird sometimes nests in the pipeline.
Rapid "overgrowing" with soot is the result of dishonest work of the stove-setter.The reduced cross-sectional area of the pipe, the wrong angle of inclination, roughness and many turns of the chimney accelerate the process of pollution. Too thin walls or insufficient thermal insulation of the pipe contribute to excess condensate.
Possible consequences of a contaminated canal:
- Reduced thrust.A constricted lumen restricts the free flow of smoke. Due to the accumulation of soot, the pipeline is badly heated, which means that the equipment's efficiency drops. Tipping over is not excluded - acrid smoke begins to flow from the firebox into the room, which is dangerous with carbon monoxide poisoning.
- Chance of fire.The carbon layer can ignite - in addition to the chimney deformation, sparks and fire pose a threat to the roofing and the house as a whole.
There is a danger of fire and nearby buildings. The roofs of neighboring houses are not insured against the ingress of hot particles of soot.
Signs and frequency of cleaning
The first symptoms that indicate problems with the chimney appear long before serious problems. However, one should be wary and take timely measures if:
- the smoke color changed from whitish, transparent to dark;
- the shade of fire in the firebox turned dark orange, and the firewood burns down almost silently, without crackling;
- to maintain the usual temperature you have to throw more coal and firewood.
As the chimney becomes overgrown, difficulties arise with the kindling of the fireplace and stove due to the lack of oxygen coming from outside.
To avoid major cleaning or partial disassembly of the canal, you should regularly inspect and carry out preventive maintenance of the chimney. Recommended deadlines for professional examinations:
- Mandatory inspection on the eve of commissioning or after repair;
- on the eve of the heating period;
- inspection of gas boilers and stoves of the first two years of service - twice a year, then - once a year;
- verification of ceramic, asbestos-cement and concrete pipes - 1 time / year;
- Assessment of the state of a brick chimney - 1 time / 3 months.
Regardless of the test performance, the stove experts advise cleaning the heaters of heating and cooking appliances every 3 months, continuous-running boilers - every 2 months.
Chemical reagents for purity
With the regular use of industrial products, it will be possible to delay the major cleaning of the chimney. Reagents are added to the furnace and, when burned, they emit components that convert amorphous organic plaque into a solid fraction. Soot loses the coupling with the walls and crumbles down. Subsequently, it is cleaned from the furnace.
Chemical products are available in the form of briquettes, powder or liquid. Characteristics of the most popular products and recommendations, the better to clean the chimney from soot, are listed below.
Series of products "Smoke" production "Ecolais"
The range of cleaning products "Smoke" company "Ecolais" is represented by three types:
The Smoke box - cleaner is easy to use and gives a cumulative effect.
Activated carbon and metal salts that are part of the box “Smoke”, when burned, react with tar deposits — moisture evaporates from soot, deposits become brittle and burn.
You should not count on an instant result - the effect of the drug continues for another 2 weeks, a noticeable effect will come in 2-3 months.
Log "Smoke" is made in the form of a bar, imitating natural wood. It is laid together with firewood when kindling. During combustion, a beautiful turquoise flame is observed - a sign that the cleaning components have entered into a thermal reaction. The advantage of using logs - aesthetics and unusual visual effect.
Analog products: “Poleshko”, log from “Vortex”, “Chimney sweeper-log”.
The granulated cleaner "Smoke" is designed for maintenance of pellet stoves and boilers. The preparation mixes up with fuel granules and is filled up in a fire chamber. Acceptable use in traditional wood-burning stoves.
Products "Smoke" is well established as a means of prevention and treatment of moderate pollution.
"Kominicek" - anti-sediment chemical composition
The preparation of Czech production "Kominichek" is produced in the form of powder, packaged in sachets of 14 g. Features of the use of purification reagent:
- it is intended for removal of soot which layer makes up to 2 mm;
- The recommended dose of refueling is 1 pack / 1 kg of firewood;
- It is unacceptable to use when open fire (fireplaces) - when burning the chemical composition exudes a strong odor.
The dosage of the cleaner for the furnace for preventive purposes depends on the type of furnace equipment:
- fireplace insert and local furnace - 14 g;
- boiler serving one floor - 14 g;
- central heating boiler - 28 g.
The manufacturer does not recommend changing the dosage of the drug. In case of severe contamination, it is better to repeat the treatment twice a month. A bag of "Kominichek" rushes into the furnace without opening, entirely.
The range of cleaning products from Hanza
The Lithuanian company has developed a line of effective reagents aimed at the destruction of creosote - resinous components, which, upon contact with water vapor, create a sticky basis for adhering soot.
Popular Hanza products:
- "Log-chimney sweep";
- concentrated granular preparation;
- resin cleaner in bags;
- pellets for maintenance of heating devices operating on granular fuel.
As part of the Hanza-cleaners - a complex of crystals. One group of components acts as a catalyst, converting wood soot into combustible gases. Other substances produce haze at high temperatures - hot fumes destroy the structure of resin deposits.
Hanza Soot Loose Soot Remover is versatile. The product is suitable for fireplace inserts, solid fuel boilers, wood stoves and open fireplaces. The shelf life of the cleaner is not limited.
Powdered reagent is easy to use - one or two measuring cups are added to the fuel chamber for fuel. At the first stage of application, in order to ensure good quality of cleaning with a cleaner, it is recommended to “refill” each furnace.
The powder is packaged in plastic containers or bags of 50 g. The volume of one package corresponds to the capacity of the measuring cup.
Granulated "Hanza" provides cleaning not only the chimney of a pellet boiler, but also the burner, door glass and heat exchanger. The product is not suitable for equipment for wood and coal. The recommended proportions based on the capacity of the boilers:
- up to 10 kW - 1 kg;
- 10-20 kW - 2 kg.
For the purpose of prophylaxis, as the use of 200 kg of fuel is added, 250 g of cleaner are added.
Spalsadz - a catalyst for burning soot
Spalsadz (Poland) - activator for the complete burning of resinous sediments and soot. Reagent in the form of a green powder, consisting of inorganic salts.When the temperature rises to 350-600 ° C, the agent decomposes into catalytic components that promote the decomposition of organic matter to water and carbon dioxide.
Features of the catalyst Spalsadz:
- not explosive and not flammable;
- does not react with ceramics, therefore deformation of ceramic elements is excluded;
- increases the efficiency of heating devices - fuel consumption is reduced by 20%;
- consumption of the drug - 1-2 kg / 1 ton of fuel (depending on the level of pollution).
The generated heat does not “evaporate into the pipe”, and the downtime for cleaning the boiler is reduced. An additional plus of Spalsadz is a reduction in sulfur dioxide emissions.
Folk chimney cleaning methods
Traditional methods are aimed more at preventing the formation of smol deposits. If the flue is clearly contaminated, they are ineffective, and some of them can cause a fire. Therefore, the old-fashioned methods should be treated with a reasonable degree of skepticism and remark that the main condition for cleaning is safety.
Self-cleaning: what to add to the furnace
Below are proposed methods, the implementation of which does not cause concern. Their essence boils down to the use of substances, the burning of which improves the separation of soot from the walls of the "smoker".
Method 1.Salt. A thin layer of ordinary salt is poured on burning logs. Sodium chloride fumes “break up” viscous deposits on the chimney.
Method 2Peel the potatoes. Excellent and affordable tool. Potato peel must be dried beforehand. Depending on the size of the furnace, a 0.5-1 pail bucket is added to the furnace. Alternatively, you can use the potato itself, sliced and dried in the sun.
Method 3.Hot water. This option is suitable for primary cleaning and punching heavily clogged chimney. 3-4 liters of boiling water are poured from the top of the pipe, neatly distributed along the walls of the channel.
Method 4.Aluminum cans. An unusual, but quite effective option for cleaning the chimney. The essence of the method is that aluminum burns, and not just smokes and changes color at high temperatures. Optimally, if the bank burns in 5 minutes.
Burning soot with fire is a risky option
The old way of cleaning the chimney is burning aspen wood. Logs are set in the oven and set on fire. It is necessary to achieve a large, but short-lived heat, which will lead to the burning of soot.
When ignited, the furnace begins to buzz, and fire arrows may fly out of the pipe, the surrounding area is covered with white flakes. The result is a cleaned chimney.
Despite the assurances of some stove-makers in the safety of burning soot, it is not recommended to resort to this method.However, aspen can be successfully used as a measure of prevention - from time to time, after the end of the firebox, it is sufficient to add 2-3 kg of alder or aspen logs to the furnace.
Mechanical soot removal technology
The most effective method to quickly bring the chimney back to normal is mechanical cleaning. The work is laborious and requires the performer to follow a number of rules.
Tools and chimney sweepers
Chimney cleaning devices used many years ago are still relevant today. Indicative list:
- Metal ruff with a diameter of 20-30% more than the cross section of the chimney. For square tubes, a hard brush is selected.
- Cable and brush holders.
- Steel round core with a cable and carbine. The diameter of the weight is 2/3 of the chimney cross section.
For cleaning it is better to choose a brush with a nylon hard pile.
Before doing the dirty work you need to take care of personal protective equipment - wear long-sleeved clothing, goggles, a respirator and gloves, shod shoes with non-slip soles.
Working conditions: safety fundamentals
During the cleaning process it is important to observe the following precautions:
- The inspection hatches of the chimney must be closed so that the soot does not get inside the room and does not spoil the finish. Hang the open fireplace with a damp cloth.
- Works are carried out in windless, dry weather.
- Be sure to use a safety cable and belt.
- It is advisable to enlist the support of one responsible assistant.
- It is strictly forbidden to start cleaning while drunk, tired or after taking medications that slow down the reaction.
It is necessary to inspect the chimney in advance for the presence of foreign objects, for example, bird's nests.
Phased chimney cleaning process
The whole course of work is a few steps:
- From the top of the chimney to remove the tip of the pipe and remove the visible dirt with a broom or a long stick.
- Perform a test run with a weighting agent. The core should break up large layers - small fragments will fall into the firebox.
- When the channel is restored, pull out the cable and connect a brush to the core.
- Clear a small area by lowering and lifting the rope.
- Similarly, clean the rest of the chimney.
- Check the inspection chamber and remove fallen soot.
The described technology is effective for straight chimneys - even at an angle of 45 ° the passage of the core will be difficult.
