Why the furnace smokes: possible causes and their elimination

Why does the oven smoke? Possible reasons are sought by anyone who has a source of heat with a rich history. Most modern citizens consider the furnace a relic of the past, an object absolutely uncomplicated. In fact, this is a rather complex engineering structure. It happens that in the process of operation the room is suddenly filled with volatile products of combustion, and the parts of the furnace become black from the soot.

If there was smoke

Practice shows that the "old lady" is still popular today. So the question is urgent. The "burzhuyki" and other "heat stores" of metal are in demand. They consist of a firebox and a chimney. It would seem easy. But why does an iron stove smoke? Possible causes: chimney narrowing due to soot deposits, loose door. Brick furnaces have internal smoke channels, which help to keep heat longer.

Part of the precedents that violate the course of the ancient process is the subject of concern for professional stoves and chimney sweeps. However, there are some problems that the owner himself is able to determine.

So, everything was fine, and suddenly a stove in the bath (and possibly in another place) began to smoke. This should alert every sane owner: maybe there was a depressurization, which is fraught with not only increased waste of firewood or coal, but also a fire.

Prevention is important

Again: to identify and eliminate the causes of smoke, which was caused by a house, dacha or sauna oven, you can use the services of professionals, but why not self-delve into the topic if there are no experienced masters nearby? Whatever it was, the owner of the stove should remember: the problem is easier to prevent than to eliminate.

Too often not to rack your brains, why the oven smokes, possible causes must be stopped at the root. At least once a year, carefully inspect the brickwork, clean the chimney. It is believed that the most suitable time for this is early autumn: it's still warm, there is no need to rush, if preventive actions are not performed carefully enough, you can repeat the process, fix the shortcomings.

It happens, the hosts are distracted by other tasks and postponed inspection and cleaning for later. Or bought a house with a hearth in a deplorable state. What to do in such cases? To increase attention to an important object! If you feel that at a stable temperature "overboard" you do not have enough of the usual daily amount of firewood (peat briquettes, coal) - this is the signal for decisive repair actions.

Devices for removing soot

Often people are interested: why does the Russian oven smoke ? Possible causes are eliminated? If there is smoke from this massive object (as well as from any other "fiery queen"), first check the thrust. It is unacceptable that it was bad or absent. The ventilation effect due to the difference in temperature outside and inside the pipe is something without which there is not and can not be any "white" furnace. "Black" is a non-free, the oldest, they say, more hygienic, fungi die in it, but it is unlikely that a modern person is ready to wash or live in a "smelly" smoked room.

Over time, the walls of the tunnel for removing smoke are covered with a layer of soot. It is believed that even an outgrowth of only three millimeters markedly reduces the heat transfer of the furnace. There are devices for removing soot. You can borrow it from neighbors or make it yourself. Option 1: take a nylon wool from a thick thread, put it with a load-stone in an old string bag (strong mesh), pass a rope through the handles. And for cleaning!

Priority of manipulation

Option 2: cut the steel wire with pieces commensurate with the dimensions of the chimney. Take the duralumin tube, drill holes in it, insert the workpieces into them. Make a loop, for which the ruff can be attached to the rope. To weight the tube, fill it with sand (some are poured with lead).

First, clean the central outer chimney. Then go on to clean up the deposits of ash and soot that have accumulated in the supercharging space. The cast-iron plate is very heavy, not everyone can lift it. If so, use the option via the burner. The most difficult stage is flushing the smoke channels.

Some moves have so-called clearing doors. Then the matter is arguing faster. There are additional bricks. Unfastened in the main brick, if necessary, remove the bars, and after the cleaning is inserted back. (It's important to tag them).

Restoration of air exchange

In your case, the chimney is clean, the doors are fitted, but this is not easier? Then why does the oven smoke? Possible reasons can be found below:

• The pipe does not have a protective cap. In windy weather, blowing occurs. Wait until the disaster is over, and take steps to install the saving "cap".
• The reason for the smoke from the oven door or the sump can be a branched tree hanging over the pipe. The obstruction interferes with the outflow of air, the gusts of the wind beat into the pipe. Reverse traction appears, the smoke does not go up, but into the room. Output: remove the branches in the near-tube space. By the way, try the method if you are puzzled by the search for an answer to the question why the new furnace smokes. Possible causes on the surface, it is only necessary to analyze the situation, to inspect the terrain: a high wall nearby? This is also a risk factor in terms of reverse air-casting. Do not necessarily break the barrier or cut all surrounding trees - protect the pipe with a hood.
• The skate on the roof is located above the pipe. This interferes with normal air exchange. Increase the pipe, and everything will go its course.
• Masonry is destroyed by bad weather (it's not for nothing that the evil winds are trying, heavy rains, severe frosts). The wind blows in the crack. Accumulation of air. Thrust is broken. In this situation, urgent repairs are needed.

Defects of the door and furnace chamber

Many people are wondering why a stove in a sauna smokes? Possible reasons:

• The cleaning door does not completely cover the hole. Temporary measure - to lay the gap with a suitable cleavage of the brick, having smeared the liner with clay, the main one - selection and installation of the appropriate screen.
• In the case of firewood, dry tomato and potato bushes, other plant residues from your favorite garden, as well as straw, hay, you need to make an ash-pit longer.
• The fire chamber is defective. In this case, smoke appears when the door is opened. It is necessary to take measures to strengthen traction. In the case of a nearby welded oven, a row of bricks will help with a rib at the same level as the fan of the door frame. If the vent channel is located below the furnace door (or at the level), a bridge of bricks at the level of the top of the door will help out, installed near the back wall of the firebox.

Having studied the above cases, you will find the answer to the question of why the new Russian oven smokes? Possible causes (in addition to constructive miscalculations) are usually associated with a furnace, a pipe, flaps, doors.

Chimney is clogged, there is moisture in it

If the smoke of a whitish shade passes through the loosely-closed latch of the summer course, check the pipe for branches, pieces of bricks (could be clogged). Also make sure that it does not need to be cleaned with soot.

In the case of filling chimneys with moisture, drying is carried out as follows: the lowest opening for cleaning is opened, in which a mini fire is made from chips (the fuel in tablets is "dry alcohol"). At the same time, the whole oven is heated. Once the thrust is restored, the opening is laid.

Why does the oven smoke? Possible reasons:

• Walls of the oven have blown out;
• The gas collector is not large enough;
• The chimney cross-section is not calculated correctly.

Maybe your fireplace is part of the furnace, and the gases go out into a single chimney. To avoid the "smoke", start the protopka from the symbol of the hearth (fireplace).

Two ovens and their chimneys are connected to the same pipe on the same level? Make a cut. Another option: connect one furnace to the riser above or below (through an inclined chimney). Smolye soot is burned directly in the chimney (dry chips, long stove matches).

In specialized stores there are tools that help keep the chimney in perfect condition. Follow the instructions, and you can remove the soot and fumes quite easily.
