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.

Kindling furnace
Ash deposit is mixed with wood resins and oils. An “explosive mixture” forms - when ignited, the temperature of soot reaches 1000 ° С and higher

In addition to natural combustion and smoldering processes, the main causes of chimney clogging include:

  1. 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.
  2. 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.
  3. 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.
  4. 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.

Brick chimney
An asbestos chimney or metal resists decomposition by acids and gases. The brick is less stable and the products of combustion gradually deform the inner walls of the channel. Rough surface quickly accumulates soot

Possible consequences of a contaminated canal:

  1. 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.
  2. 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.

Reverse thrust
A disturbing symptom is the entry of smoke through the lumens and slits of the heater inside the room. It signals a significant deterioration in thrust and the need for a quick chimney service.

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:

  • box;
  • log;
  • granules.

The Smoke box - cleaner is easy to use and gives a cumulative effect.

Smoke box
How to use: remove the labels, put the box in the firebox, pour liquid on it (attached in the kit) and set fire to it. Burning time - 1-1.5 hours

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.

Chemical reagents
Regardless of the form of release, the basic scheme of the operation of the reagents is the same: 1 - igniting the preparation, 2 - coating the resin with active gas, 3 - drying of the deposit, 4 - gradual cleansing effect

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.

Powder "Kominichek"
The composition of the cleaner: copper chloride and activated carbon. Soot is removed due to the catalytic reaction - heated pellets melt and release chemical components that transform soot into oxide

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.

Log Chimney sweep
The “log-chimney-sweep” burns through in 2 hours, the period of validity is 2 weeks. To improve the effectiveness of a preventive cleaning procedure, it is desirable to repeat. When laying in the furnace packaging is not necessary to remove

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.

Hanza remedies
The calculation of the volume of the mixture is based on the capacity of the furnace and the degree of contamination. To prevent clogging of the chimney, the frequency of use of "Hanza" - each 4-5 kindling

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.

Combustion catalyst
Regular use of Spalsadz reduces tar deposits on the chimney and eliminates carbon monoxide emissions to the environment.

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%;
  • non-toxic;
  • 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.

Chimney Cleaning Salt
Salt incineration will partially warn and slow down the formation of tar. To cope with old growths of soot "salt method" is not able to

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.

Potato burning
The release of starch by burning potatoes softens soot growths. Part of the pollution is eliminated, and the remaining soot is easier to mechanically clean.

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.

Water cleaning
The fumes soften the solid fractions of the bloom - soot begins to flake out of the chimney along with the smoke. The method helps to remove the unpleasant smell of burning

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.

Cleaning cans
The method is applicable for heating systems on coal and wood. The frequency of preventive measures - 1 time for 10 fireboxes

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.

Chimney fire
Not every chimney will stand the test of fire, as soot in the channel burns out at a temperature of + 1100 ° C. Sparks can trigger a fire.

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:

  1. Metal ruff with a diameter of 20-30% more than the cross section of the chimney. For square tubes, a hard brush is selected.
  2. Cable and brush holders.
  3. 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.

Nylon brush
Polyamide bristles take the form of a channel, and, unlike a metal scraper, does not scratch the internal walls of the chimney. High flexibility nylon helps get rid of plaque in hard-to-reach places of the chimney

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:

  1. 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.
  2. Works are carried out in windless, dry weather.
  3. Be sure to use a safety cable and belt.
  4. It is advisable to enlist the support of one responsible assistant.
  5. 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.

Chimney cleaning
If the socket is low, it must be pushed in the direction of the combustion chamber. Highly positioned item available from the top.

Phased chimney cleaning process

The whole course of work is a few steps:

  1. 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.
  2. Perform a test run with a weighting agent. The core should break up large layers - small fragments will fall into the firebox.
  3. When the channel is restored, pull out the cable and connect a brush to the core.
  4. Clear a small area by lowering and lifting the rope.
  5. Similarly, clean the rest of the chimney.
  6. 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.

Flexible hose
Multiprofessional professional brushes on a flexible shaft designed for cleaning chimneys, ventilation systems and sewage. The marking on the cable allows you to control the depth of passage
