How to clean the chimney with his own hands

stove heating still very early to write off - they actively use on the huge number of people still on around the world, in cities and in rural areas in poor regions and in quite wealthy and prosperous countries.Moreover, in some extent, we can say that the domestic stand-alone heating facilities are experiencing "triple birth", since both the furnace and fireplaces rapidly coming into fashion, and little country building a modern house without them.

Get in his disposal a coveted stove or fireplace - this is not all.Such structures - are always the object of increased danger, and therefore it is extremely important to know how to exploit them.With the order the furnace stoves in terms of everyday use, the types of wood necessary for them - this owners acquainted quickly enough.But what is surprising - a negligible number of owners know how to clean the chimney with his own hands, and even less - making it virtually.

This situation can not be called normal.Safety of operation of furnaces and fireplaces in living areas on a good half depends on the good condition and correct operation of the flue

system.Forgetting about it, negligent owners are subjected to an extremely high risk of life and health and own , and their loved ones at risk the preservation of property, and acquired property.

Slightly theorized and and and Stora

the cause clogging chimney

Why same on the walls of the tube are formed nodules that require regular cleaning?

first factor is due to the most banal reasons - by the burning of wood.It is - quite a complicated physical and chemical process consisting of several stages.Depending on the type of furnace (fireplaces and boilers), the location and internal channels configuration for discharging the combustion products from the construction of flues, the type of used wood and quality (or other fuel) depend number and completeness of combustion stages ( phase flame or smoldering phase), which can change a few times - the other.

- Thus, in the decay mode is mainly burning t t Verde components - coal.Gaseous products thus are too low concentrations - as occurs at the beginning of the furnace until it reached the optimum temperature, and the process of allocating combustible pyrolysis gases not yet started "full."These combustion gases condense quickly, so burning at this stage accompanied by the release of dense white smoke.

- mode active flaming main source of heat is becoming pyrolysis gases.With increasing temperature of the flame changes color (to close to the bright white), and the smoke becomes almost imperceptible.But gradually their concentration decreases, and when one tab firewood rapid flame again soon replaced by a stage of decay, for the reason that the gases are already out, and burn The substance tv item ANOVA all less.

Whatever it was, in flue pipe anyway leaves a lot of products of combustion.Mainly by incomplete combustion of soot becomes (fine carbon particles), organic complex compounds, resin, carbon monoxide (carbon dioxide).Almost all of these products are flammable, and at certain conditions may even form an explosive mixture.

Under complete combustion of the organic content in the smoke sharply reduced, and the main products of the inlet are water vapor, carbon dioxide and sulfur gases .

• terms of clogging chimney pipe smoke is the greatest problem, most are not fully saturated Burned carbon residues (ash), heavy resins.Therefore it is very important to know how to choose the best firewood oven - not every wood is suitable for these purposes as by its specific heat transfer, and in biochemical composition, ie concentrations of heavy tar.Increased resinous always different from coniferous wood pore qq revesiny.By the way, not only this feature makes them undesirable for use in everyday life - just look at the chart to see how they lose and density, and heat transfer firewood from deciduous trees.

resinous substances into smoke on the internal surface of the tube, becoming an excellent "glue backing" for the build-up layers Sazhnev.

• But this still not all.Considerable dangers of regular use of freshly cut, raw or improperly stored firewood.Increased moisture content of wood - this is the reason of abundant condensation on the walls of the tube, which is also very good "lie» rising up tiny soot particles.

• All would still nothing, but in our time, many owners of houses considered stove and even as a "universal waste recovery."This refers to the fact that a large amount of household waste sent to the furnace.It turns out that through the furnace runs a huge number of polymers, food waste and other substances, that when burned gives the whole "bouquet" of a variety of fats, resins, esters, fireproof solid particles, that very quickly lead to the overgrowing tube lumen.

• challenging part of the chimney blockage factor can be poorly executed stovemaker work. narrowed pipe channel, too many wrong turns or angle, the remnants of the solution on the inner surface of the wall - and etc .- All this provokes an outgrowth Sazhnev waste in such places.In addition, poor insulation of the chimney or ill-conceived, does not correspond to the scheme poryadovoy thickness of the pipe wall can lead to overly abundant condensation - which yet another step in the direction of the emergency.
• can not exclude the possibility that the unprotected top tube cap in the summer, when the stove is not in use, decided to twist nest any bird.In addition, the pipe can get random debris, such as leaves palye.With these details, it would seem, sometimes quite difficult to grow punched cork.
• soot that collects on the walls, can under the influence of any external causes one piece peel off and fall down .If the fragment is large enough, it often happens that he gets naperekos cavity in the pipe, and then on the basis of this "jumper" quickly grows a full blockage.

The dangerous clogging chimney pipes

reasons - a lot, but what would have clogged or was caused by it carries a lot of very serious threats:

• Narrowed gaps chimney pipe sharply reduce cravings, and therefore very likely to reverse movement of smoke - in the room, from the combustion chamber.In addition to smoke - itself unpleasant, dramatically increases the threat to get carbon monoxide poisoning.
• Low craving leads to an increase in the volume of condensation on the inner surfaces of the pipe, that is, further clogging of the chimney can go even faster, like an avalanche.

• thick soot layer is strong enough thermal insulator, which does not give channels oven heat to the desired temperature.This situation - always, without exception, leads to a drop in the efficiency of the heater, to the consumption of fuel used.
• soot - unburned solid residues, but this does not mean that they are non-combustible.Conversely, a thick layer of sooty deposits when creating certain conditions may easily take a flame, such as from a rising gas stream of sparks.This not only leads to burn-pipe walls - dramatically increases the vulnerability of the entire house.This situation - one of the main causes of fires in buildings, equipped furnaces.

• Overgrown soot chimney becomes a real fire threat for the neighboring buildings - from this not cleansed pipe often will fly "fiery tails» - sheaves hot solid soot particles.

Such situations are described without exaggeration.All these troubles can occur in complex, almost simultaneously, and the consequences are sometimes the most tragic.That's why you can never forget regular inspections and Cleaning.

How often should cleaning carries

Perform cleaning strongly "overgrown" sooty deposits of pipes - an extremely difficult task.It is best to - not bring to this, and regularly check-ups and preventative cleaning of the chimney.

There are recommendations on the periodicity of such events

Name of preventive measures and the type of equipment	Frequency of work
Routine inspections of the chimney condition and chimney channels furnaces
Check any equipment	Immediately after the installation, prior to commissioning, or after any whatsoever repairs
Check any equipment, seasonal scheme	Immediately before the start of the heating season
Check chimney systemsgas furnaces and boilers	not less than twice a year during the first two years of operation in the future - at least once a year.
Checking brick chimney - irrespective of the type of furnace or boiler	at least once in three months
Check asbestos, heat-resistant concrete or ceramic chimneys	at least once a year
Chimneys Heatingand heating and cooking stoves	at least three times a year - before the heating season, for him, and at the end
Cleaning the chimney channels in the pipes - at least identify deficiencies in inspections and in addition,during the active period of operation:
in heating and cooking stoves	least once in
three months in continuous furnaces	at least once in two months
in a constantlyused cooking stoves	at least once a month
in regions which are peculiar to severe winters with low temperatures, at least twice a month to check headroom chimney to prevent the freezing of ice crust to form a blockage

what do you need - probably already clear all .But who will do it?

Where can I find a chimney sweep?

But it is in our time - the problem, and considerable.Chimney sweepers - professionals, in the sense that invest in this concept for centuries, there are not so many.

way, the need for the emergence of such specialization in the Middle Ages directly associated with the massive urban fires, from time to time shook the densely infested many European cities and literally destroying them to the ground.It is awareness of the direct relationship of risk of fires and chimneys state, understanding the importance of qualified maintenance of furnaces and pipes.And in the XVII ÷ XVIII centuries first in the German principalities, and then in the other Nordic countries appear guild (shop) specialist - chimney sweeps.In Denmark, for example, it has even been carried out by royal decree, which once again proves the importance attached to their work.

way, it is - one of those professions which are associated with the greatest number of all kinds of superstitions, omens and superstition, urban legends and amazing improbable stories.
