It is very unpleasant when in the middle of winter in a private house there are some problems with heating equipment, for example, with a gas boiler. Under the law of the Murphy, the heat source begins to haand in the coldest days when its shutdown leads to a rapid cooling of the coolant in the system, and after it is the whole building.

The first thing that comes to mind is to call the masters, who will solve your problem. The thought is true, but because of many reasons, the arrival of a specialist can stay for several hours, and even days. Instead of freeze slowly, try to find out the reason why the gas boiler goes out and eliminate the malfunction with your own hands. We will tell you what to do in such a situation.

Why goes out the burner of the gas boiler

The answer is simple - the fuel supply overlaps, installed on all heating units using natural or liquefied gas. Turning off the burner and the attenuation of the gas boiler will occur in any of three cases:

• decreased or disappeared in chimney;
• gas pressure in the feeding line fell below the norm;
• flame of the burner itself.

For reference. The Italian production gas valves of EUROSIT or the American Honeywell brand are performed as automatic disconnecting devices.

The automation can work from both the effects of external factors and due to the breakdown of any part of the heat generator. In this regard, it is easier to deal with non-volatile floor boilers of a simple design, since they literally have nothing to break, and the burner will often fade due to external reasons than from faults. These include Danko brands, Zhytomyr, Athon, Ross and other producers of gas-wide devices from the countries of the former USSR.

A more modern wall-mounted electro-mounted boiler, equipped with a closed combustion chamber, is a miniature boiler room, equipped with additional protection steps, disconnecting fuel supply in such situations:

• the movement of the coolant in the heating system was stopped (the duct sensor is triggered);
• decreased or air supply ceased, which signals the press service (another sensor);
• in the household power grid, voltage jumps occur;
• when the electricity is disconnected.

Note. At the moment, high-quality wall boilers offers only one Russian manufacturer - NEVA, the remaining part of the market is occupied by imported brands from Europe and Korea.

Varieties of household heating units, burning natural gas

When a wall-mounted heat generator begins to flush, then it is not easy to establish it, but a number of faults can still be eliminated with their own hands. How to do it correctly - read further.

Attening boilers with an open combustion chamber

By default, we consider the situation when the heating unit worked several seasons without complaints, and now for some reason began to go out. An extended list of reasons forcing the automatic valve to stop the supply of gas, it looks like this:

• thrust in chimney disappeared;
• there were problems with the supply of natural gas, which is why its pressure in the pipe has fallen below the norm;
• the boiler is not enough air for burning, which is why the flame goes out;
• the burner blossoms a strong wind on the street either there is a flame separating with a strong draft inside the house;
• gas boiler hardware faults - the failure of the thrust sensor or thermocouple.

Lyrical digression. The attenuation of the homemade device of the home team may not be noticed immediately, especially when the unit is installed in a separate room. The problem is detected when the air temperature has already decreased in a private house.

Furious burner boiler - radiators cooled

So, if you have the main burner of the boiler, then look for the cause in the specified sequence, starting with the check of thrust in the chimney. Let's consider in detail every step.

Problems with cravings

The first thing that the hosts of atmospheric gas boilers should do when attenuation of the burner - check the craving. Take matches or a candle, burn it and bring it to the viewing window and watch the behavior of the flame. If it rejected the side of the opening, then everything is in order with the burden and can be moved to the next step.

If the flame is not rejected, then the thrust in the chimney is not

The fire remained motionless - the reason for the burner is detected, thrust disappeared in the chimney pipe. Your actions:

1. Open the window to the boiler room so that the air flow is guaranteed to be guaranteed.
2. Disconnect the chimney section connected to the outlet of the heating unit, after which check the presence of thrust in the smallest tube. If it is, you need to disassemble and clean the gas boiler itself, as described in.
3. If the traction is not detected in the main channel, then it is probably clogged. Find the hatch for maintenance and cleaning, it is located in the boiler room below the connection location either on the street. Open the hatch and impose inside the mirror to see the outlet. If it is not visible, then the chimney must be cleaned.
4. Inspect the headguard of the pipe from the outside, during the summer period there could appear the bird's nest. Another option is a solid frosting of the cap, covering the chimney cutting. So it happens with severe frosts when the ice is overlapping the working section of the chimney.

Oblaged flue pipes with caps

Important! The rules of operation of gas-wide installations directly prohibit the umbrellas from above in chimney pipes. If you have such a cap, it must be dismantled. It is allowed to apply only open.

Briefly about the causes of clogging of smoke channels:

• the lavety brick walls are destroyed from the effects of condensate, why the passage cross section is clogged with construction trash;
• in the cheap sandwich chimney from the inner wall, a zinc coating can be derained and overlapping the channel in the form of a thin film;
• 2 boilers are connected to one chimney - gas and solid fuel, so it is scored soot;
• foreign items from the vital activity of birds can fall into the pipe.

In the chimney pipe there are not only a lot of soot, but also birds

Pipe cleaning may not give results when its walls are frozen at low temperatures on the street. The fact is that the combustion products of gas heat generators have a relatively low temperature (up to 120 ° C) and are unable to warm the chimney so that a stable thrust arose. Since you will not deal with insulation in the middle of winter, you will not become, then the output is one - to buy a disposable burner with a can, light it and turn it into an open clear hatch. When the frozen channel warms up, run the boiler to work, but do not turn off the boiler, otherwise the procedure will have to be repeated.

Information for reflection. Situations occur when a two-or-three-story cottage is underway at the next site in close proximity to your home. As a result, the smoke trumpet can get into the leeward zone of the neighboring building, and this leads to a decrease in thrust, as a result of which the gas boiler flies. Since it is not possible to prohibit neighbors, you can have to increase the chimney for 1-2 m, in order to withdraw it from the stagnant zone.

Other reasons for the deterioration of thrust in the chimney and blown by the wind (from left to right): Low section of the cutting pipe, obstacle in the form of trees and downward air flow

The simplest and cheap way to struggle with wind into a problem chimney is to install a german at the outlet of the gas boiler. True, when changing weather conditions, its position will have to be adjusted, because the heater will not reach the optimal mode of operation with half the channel, and avgar can go into the house. Therefore, the best way to defeat the tipping of the thrust is to increase the smoke pipe for 1-2 m.

Gas pressure reduction in highway

Making sure that the thrust in the chimney is present, go to the next step - checking the fuel supply. A sign of low gas pressure at the entrance is a burner fading without visible reasons, and the flame on the stall of the boiler continues to burn. What can be done:

1. Check how well there is gas from the pipeline. First, close the door to the boiler room, swipe the window and unscrew the supply hose from the heat generator. Briefly open the gas crane. A sign of a good feed is a loud hiss of the hose and a strong smell of odorous methane. Install the hose in place and check the sealing of the joint with soap solution.
2. If fuel does bad, clean the net gas filter, after which try to ignite the wick and the main burner of the boiler. With a negative result, call the appropriate service and call the masters - the gas driver.

Attention! Before performing any manipulations with the fuel pipeline, be sure to break the gas with a crane!

On the way to your heating unit, the highway can clog in another place - inside the gas meter. So it happens after the repair of external pipelines, when rust or scale from welding gets into them. But to disassemble the accounting device for cleaning is prohibited, only the Master call will help here.

Counter and filter on the submarine gas pipeline

At the beginning of the heating season, when thermal equipment is massively launched in private homes, the fuel supplier is obliged to monitor the pressure in the highway and increase the volume of the gas supply. Sometimes the service reaction is delayed, with the result that consumers who are in the impasse of the network may not be enough fuel. You can't do anything here, except to make an angry call from the company - a supplier or run the second boiler on electricity or firewood (if any).

Lack and rejunction of air

Any of these phenomena leads to the fact that the gas boiler can periodically shine. For its normal operation in the fiber must come to the dwelling air through the ventilation channel or from other rooms. At the same time, severe drafts can not be allowed to blew the burner operating in low-power mode.

Ensure the lack of oxygen simply: Open the nearest window and watch the flame behavior. If the work of the burner has stabilized, then the cause of the attenuation is clear. Tell me why it happens:

• you installed sealed plastic windows and air flow inside the house stopped;
• one or more interroom doors was replaced and the lumens between the sash and the floor, where the air had previously pasted, decreased strongly;
• you put a powerful kitchen exhaust, pulling part of the air flow on yourself;
• the same effect is observed when installing the forced hood in the toilet and the bathroom.

Scheme of atmospheric burner

Buying various exhaust devices, remember that the remote air needs to be compensated for by the influx, otherwise the thrust in the chimney will decrease, and then the belch in the opposite direction. Then the question will rise - what to do, when the gas boiler will bloom the wind. On plastic windows you need to put special supply valves, and to compensate for forced exhaust it is necessary from the street.

Council. Purchase and installation of the supply installation - the pleasure is not cheap. A compromise can be the organization of a natural influx into a room with an excess of heat (for example, in the kitchen or directly to the boiler room), where street air will have time to warm up.

Separate history - Parapete gas boilers and convectors with short coaxial chimney coming out directly through the wall. Since combustion products are moving along them naturally, then with an unfavorable arrangement of the smoke exit, the burner is often observed. The problem is solved like this: Determine the direction of drafts in the yard and tightly close the protective grille from the windward side.

What to do when the wind poices in coaxial chimney

Faults of atmospheric boiler

In non-volatile floor heat generators there are several elements delivering trouble over the years of operation. Signs of their breakage are as follows:

1. When trying to ignite the scarlet, it shoes immediately after releasing the button on the valve. This means that it has become unusable to the thermocouple heats from the wick and maintaining an electromagnetic gas supply valve in an open state.
2. Outdoor gas boiler does not ignite at all, even the ignition burner. This testifies to unreliable contact in the electrical circuit connecting the automation unit with the thrust sensor. The element itself fails.
3. When the main burner is lightning with difficulty, it works with interruptions and cotton, and the color of the flame is yellow, then the main fuel jigger clouded.

Thermocouple (left) and traction sensors of different manufacturers

It is a copper tube with a bimetallic element at one end. From the second side there is a capillary connected to the gas valve. The joint of heterogeneous metals was washed by the flame of the stobble, due to which the voltage 20-50 Milvololt is produced, which holds the valve electromagnet open. Thermocouple is not subject to repair, only replacement.

Briefly about the principle of work. When ignition, we open the valve manually, after heating from the wick, it keeps the thermocouple. A traction sensor is turned on in series with an electromagnet, a breaking chain in case of overheating from gases accumulated in the smoke collector.

The thrust sensor is the part in the form of a tablet, placed at the output of combustion products and connected to a gas valve with two wires. Check the performance is easy - close the contacts where these wires are lounged and try to ignite the burner, if successful, change the sensor to the new one. Since meager voltage comes from it, the cause of the malfunction sometimes becomes old connecting wires that create a large resistance. The question is solved by their replacement or cleaning all contacts.

Thermocouple is attached on the same flange with a stall and is washed by a flame

Shoot with your own hands the gas grinding device of the boiler to clean the fatter, we do not recommend. But if there is no other way out, do not forget to block gas before starting work, and then unscrew the fasteners. Try not to disassemble the unnecessary junctions of the gas highway, and after the assembly, check them on the tightness of the soapy solution.

Addition. The burner of the outdoor heating unit will not turn on to work when the circulation pump installed outside the boiler has failed. It will heat the water located in a boiler tank, after which it will turn off until this heat carrier cools.

Repair of wall and turbocharged units

Wall-mounted gas boilers with an open and closed combustion chamber are more complex devices equipped with modern electronics and security elements. But here some problems can be solved on their own. All described above manipulation with a check of thrust, fuel and sensors are as relevant for atmospheric heat generators in the wall design.

To find malfunctions in a wall-mounted electrogasse boiler, it is necessary to arma your product instructions and a cruciform screwdriver, other tools are hardly needed. In the technical passport, fault codes are prescribed on the heater display, and the screwdriver is needed to remove the front panel.

There are 3 non-working conditions of the heat generator:

1. The boiler is turned off completely, no indicator is shining.
2. The unit is enabled, the display is on and the network indicator is on, but the automatic ignition does not occur.
3. There are attempts to launch the main burner, but after the ignition it immediately goes away.

Council. With the full failure of the wall boiler connected to the housewall, always check whether the voltage is supplied to it. The cause of the problem can be a worked automatic machine, located in a camshaft. The moment is the second: almost all import units are sensitive to the location of the phase and the question is often solved by switching the plug in the outlet so that the contacts are changed in places.

The fuse block is on the boiler electronic board

Making sure that the stress to the heater is supplied, we can start repairing state number 1. To do this, unscrew the front panel of the gas boiler with a screwdriver or key and remove it or fold the front cover (depends on the model). Then the algorithm is:

1. Lay the fuse block and check each of them multimeter or visually. Surely there is one blown.
2. As a rule, the spare fuse is glued from the inside to the front panel. Put it in place of the burnt or buy a new one (exactly the same nominal value!).
3. Try running the heating unit. If he earned, the repair is over, put the lid into place.
4. The device turned on and again "died"? It remains only to call the masters, since the problem is more serious.

Council. After opening the panel, carefully inspect all the elements of the heat generator for the objects of the joints, torn off or discharged wires and burned parts on the board. Having found the latter, immediately call a specialist. For more information about the troubleshooting algorithm in the wall-mounted gas boiler, our expert Vladimir Sukhorukov will be available in his video:

With the other two non-working states, the display reflects the error code for which you can define the problem, looking into the product passport. The expert recommends the following: When the documentation in front of the error code is written "Contact the service department", then it is necessary to do, you yourself can not cope with the breakdown. You can independently eliminate such errors:

1. A mud filtering heat carrier from the heating system is scored. Disconnect the heat generator from the house of the power grid, overcoat the cranes and clean the element grid.
2. The built-in circulation pump does not work. Causes - Rotor Enhancing or Air Cork. In both cases, unscrew the large screw (stands in the center of the pump) and release the air or turn the rotor with a screwdriver. Act carefully, out of the hole flows some water.
3. When the boiler pressure gauge shows low pressure, and there is no leakage in the heating system, you need to swipe the air into the expansion tank, mounted inside the heating unit. The pressure from the air side of the membrane should be less than 0.2 bar than in the system. Read more about pumping the tank.
4. If leakage is detected at low pressure, it must be fixed, and then add to the water system.

Note. The display will not show an error in the situation when the electrical circuit of the room thermostator or its own thermostat of the gas boiler is broken. More information - in the second part of the video from our expert:

Conclusion

Of course, overcome a serious malfunction of the heat generator to the ordinary user will not succeed. But if the gas boiler goeshes because of some small problems, then you will not only be able to return warmth to the house, but also to save money that you have to pay for a call to a service specialist. The main thing is to confidently take up work, follow recommendations and not to do extra movements so as not to apply additional harm to the source of heat.

Gas boiler is the most important element of the offline heating system. Well, if he smoothly warms the water throughout the heating season and does not force on his work. And what to do if he suddenly suddenly flies or spontaneously turns off after a few hours after the ignition?

In such cases, the main thing is not to be panic. Obviously, a long-term boiler in non-working mode can lead to extremely undesirable consequences not only for tenants, but also the entire system as a whole - it can definitely and come into disrepair. Therefore, if something incomprehensible is starting with a boiler periodically - it suddenly flies, the wind is noise in the combustion chamber and blossoms the flame or the dashboard display lights up any emergency icon, you need to quickly diagnose and determine the causes of the malfunction.

First of all, it is not necessary to pay attention to the advice of "Corresponders", which recommended "simply" to change the boiler and chimney. This, of course, an effective method, but it will always be possible to resort if anything else remains.

First you need to understand that the gas boiler is a complex electronic system that is fully controlled by automatic.

It is worth some of the sensors to file a malfunction signal, the automation immediately turns on to work and gives a command to stop the entire system. So the main reason why the gas boiler goes out, it may be both in the thermal unit and in some of the other nodes:

• gas pipeline;
• smoke system;
• contours of heating and hot water supply;
• electrical network.

Insufficient pressure Gaza

Despite the seeming evidence, quite often problems are associated with the lack of normal gas pressure at the entrance to the boiler. This may be caused by both the problems of the gas transmission network itself (which is rare enough) and internal reasons:

• Faulty gas meter. Sometimes the counter encourages, and it ceases to pass gas in the desired volume. To check, you need to see if the countable mechanism works - its testimony should change. Often a faulty counter of the noise or other suspicious sounds;
• Problems with leakage sensors or temperature. Gas services usually require a special equipment at the inlet to the boiler, which monitors the level of gas concentration and temperature near the thermal unit. When you trigger such sensors or their malfunction, the boiler is immediately turned off;
• Loss of tightness of compounds. Gas leakage can cause a drop in its pressure, which is why the automation system is triggered, and the gas boiler shoes. Usually this situation is easily diagnosed on a tangible specific smell.
  

  To diagnose and eliminate malfunction, you need to check all the joints using a sponge and soap foam - bubbles will appear in leakage places.

Chimney problems

The goodness of the chimney is, of course, the main thing is that you need to check when you want to find out why the gas boiler is turned off, as many causes of malfunction can be associated with it.

Formation of land

Why is it often formed in the chimney? The fact is that hot couples, who, together with the combustion products, falls into the chimney, climbing it, is cooled and settled on the walls in the form of condensate droplets. Condensate over time freezes and turns into a thick layer of ice. As a result, the thrust decreases greatly, automation turns on, and the flame in the burner will go well.

The solution to this problem is the chimney must be cleared and then insulate that the condensate does not freeze, but the window is down, in a special capacity.

Reverse traction

This problem often occurs when the wind is strengthened on the street or when it changes its direction when the air falls into the chimney and blooms the flame in the boiler.

It is very dangerous, especially if an old gas boiler with poorly running automation is used - combustion products are not removed, but, on the contrary, the wind into the room is ejected.

What to do in such cases?

• This effect may occur at a certain direction of the air flow and the pressure of the atmosphere, when there is a vacuum at the entrance to the pipe, the wind is placed there, and because of this, the cauldron flies. Sometimes this is due to the insufficient height of the chimney - it needs to be just a bit increasing, so that its upper point is 50 cm above the roof of the roof:
• Some specialists advise a variety of headings on the upper part of the chimney: fungi, umbrellas, deflectors, etc. Such solutions may be suitable for solid fuel stoves, but it is prohibited to put them on the gas chimney;
• Often the flame in the burner of the atmospheric boiler goes out due to weak supply ventilation. Sometimes it is enough to open the door or window, and the gas lights up again. In boiler houses for improving the air exchange, make a vent hole at the bottom of the door and close it with a fine grid;
• Sometimes the cause of the pipe can become the root of the pipe. The wind blows the wind and interferes with the normal operation of the chimney. The only obvious decision is to replace the chimney pipe.

Malfunction automation

In the turbated boilers, the built-in fan creates a built-in fan. It may fail - in whole or in part. His diagnostics is quite simple - in a non-working condition, it or completely ceases to publish any sounds or, on the contrary, is too much noise. Possible method of its repair is presented in the video below:

The atmospheric gas boiler usually works in a complex with a thrust sensor, which is turned on by increasing the temperature in the smoke, when it poices hot steam, not in the pipe. The failure of this sensor is one of the possible answers to the question of why the burner rushes.

Interruptions in power supply

It happens that the voltage in the electrical network drops below the permissible level. The boiler at the same time immediately swallows, because modern automation can determine the reduced voltage. When recovering power supply, the same automation will turn on the burner, so most of these failures can pass unnoticed. However, such a mode of operation is harmful to electronics, so it can eventually fail. So if suddenly the gas does not light up when the network appears in the network, perhaps something happened with automation. To avoid a similar scenario, it is better to buy a voltage stabilizer.

Cote-related problems

All systems are checked, but there is still no heat? So it's still in the bolet itself. We will understand why it does not work. Malfunctions can be manifested as follows:

• The burner does not turn on or burning weakly. Perhaps the nozzles were clogged. They can be cleaned with a soft brush or thin wire. In addition, the air can be hit in the gas highway (especially if the connection node was disassembled). Usually in such cases the gas boiler is blocked, and the error code lights up on the display. It is necessary to repeat, dropping the lock (how to do it is written in the instructions);
• The burner does not turn on when trying to manual or automatic ignition. Perhaps the gap in the plane electrode is disturbed, contact with a toxade wire or closed the air supply filter to the burner. Adjust the clearance on its own quite difficult, but to clean the filter and check the connection of the wire - quite real;
• The burner flies after some time burning. It may be contaminated by the ionization electrode, the gap in it or the connecting wire was disappeared. It is necessary to do the same as in the previous case;
• Out of flames. With such a malfunction, the nozzle is strongly noise (or a characteristic whistle is heard from it). It is necessary to adjust the gas pressure on the stall. The separation is also possible with an excessively high thrust and increased supply ventilation (the air blossoms the flame in the burner). This situation may occur, for example, with an excess height of the chimney pipe;
• The boiler is noise and spontaneously turns off. The reason can be a breakdown in the pump or the built-in fan (for turbocharged models), the failure of the thermostat (water boats), a separation or flame skill.

It should be noted that many of these faults are accompanied by an output to the error code display, according to which it is much easier to deal with what is happening.

In addition, some boilers are phase-dependent, i.e., sensitive to the change in the location of the "phase" and "zero" contacts on the power supply. Quite often, it is possible to repair the non-working boiler with a simple change in the location of the electric plug in the outlet (turning it at 180 degrees).

Now, if nothing of the above helped, you can call a service specialist. And only if his diagnosis is disappointing, you will have to buy a new boiler.

If you think well into the burning process, the question involuntarily arises: why does the flame go out by itself? After all, combustion products are carbon dioxide and water vapor - non-combustible substances, unable to maintain burning. Consequently, the flame from the first moment of combustion should be surrounded by non-flammable substances that interfere with the influx of air; Without air, the burning cannot continue, and the flame should go out.

Why doesn't it happen? Why burning lasts continuously, while there is a stock of a combustible substance? Just because the gases expand from heating and, therefore, become easier. Only due to this, the heated combustion products do not remain on the site of their formation, in the immediate proximity to the flame, and immediately displaced the upward air.

If the Archimedes Act did not apply to gases (or if there were no gravity), every flame, the chases a little bit, would go to themselves. It is very easy to ensure that the products of his burning are destructive on the flame. You often use it, I do not know how to sneak out the fire in the lamp. How do you blow a kerosene lamp? Blowing on top, i.e., drive down, flame, non-combustible products of his burning; And it goes out, deprived of free air access.

Why water extinguishes fire?

At such a simple question, they do not always know how to answer correctly, and the reader, we hope, will not attend us if we explain in brief, which is actually the action of water on fire.

First, touching the burning subject, the water turns into steam, taking a lot of heat at the burning body; To turn steep boiling water into steam, you need to fall more heat than heat than to heat the same amount of cold water up to 100 degrees.

Secondly, the pairs formed at the same time occupy the volume, hundreds of times more than the water generated; Surrounding the burning body, the pairs push the air, and without air the burning is impossible.

To increase the flame force of water, sometimes mixed up to it ... powder! This may seem strange, but it is quite reasonable: the powder is quickly burning, highlighting a large number of non-combustible gases, which, surrounding the last-minute items, make the burning make it difficult.

How to stew fire with fire?

You have heard, it is likely that the best, and sometimes the only means of fighting a forest or steppe fire - from the ignition of the forest or steppe from the opposite side. The new flame goes towards the raging sea of \u200b\u200bfire and, destroying the combustible material, deprives the fire of food; Having met, both fiery walls instantly go out, as if making each other

A description of how this taking the extinguishing of fire in the fire of American steppes, many, of course, read from Cooper in the prairie novel.

Is it possible to forget that dramatic moment when the old man Savior saved from the fiery death of travelers caught in the steppes by fire? This is the place from Prairie. "The old man suddenly accepted a decisive look.

It's time to act, "he said.
- You have tried too late, a pathetic old man! - Middlton shouted. - The fire in a quarter of a mile from us, and the wind carries it to us with terrifying speed!
- That's how! The fire! Not really I'm afraid of him. Well, well done, full! Apply the hands to this dried grass and bring the land.

In a very short time, the place of the feet of twenty in diameter was cleared. The trapper brought women to one edge of this small space, saying that they cover their dresses with blankets, easy to ignite. Having accepted these precautions, the old man went to the opposite edge, where the elements surrounded the travelers with a high, dangerous ring, and, taking the pinch of the most dry grass, put it on the shelf of Ya and set fire. Easily flammable substance flashed immediately. When the old man threw the glowing grass into a high thicket and, having flown to the center of the circle, began to patiently expect the result of his business. The destructive element with greed attacked new food, and in an instant the flame began to lick grass.
"Well," said the old man, "now you will see how the fire will fight fire."
- But is it really not dangerous? - exclaimed surprised Middlton. - Do you get closer to us the enemy, instead of moving it?

Fire, increasing everything, began to spread in three sides, having silent on the fourth due to lack of food. As the fire increased and raved everything more and stronger, he cleared everything in front of him all the space, leaving the black smoking soil is much more nude than if the grass in this place was beveling oblique.

The position of the fugitives would still be risky if the place purified by them did not increase any extent that the flame was surrounded from the rest of the parties.

After a few minutes, the flame began to retreat in all directions, leaving people with a cloud of smoke, but in full safety from the fire flow, which continued rabbid ride.

The spectators looked at a simple tool used by the trapper, with the same amazement, with what, as they say, the sacredturians Ferdinand looked at the Columbus method to put an egg. "
This method of extinguishing steppe and forest fires is not so, however, simple, as it seems at first glance. Only a person is very experienced to use the counter fire to extinguish the fire - otherwise the disaster can even intensify.

You will understand what kind of snorkee need for this, if you ask yourself a question: why the fire, grilled by the trapper, ran towards the fire, and not in the opposite direction? After all, the wind blew from the fire and drove fire for travelers! It would seem that the fire caused by the trapping should not meet the fiery sea, and back on the steppe. If it happened, the travelers would be surrounded by a fiery ring and inevitably died. What was the secret of the trapper?

In the knowledge of a simple physical law. Although the wind blew in the direction of the burning steppe to the travelers - but there was ahead, near the fire, there was to exist the reverse air of the air, towards the flame. In fact: heating over the sea of \u200b\u200bfire, the air becomes easier and displaces upside down from all sides the fresh air from the steppe, not affected by the flame. Near the boundary of the fire is installed therefore the air traction towards the flame. Slage the oncoming fire is necessary at the moment when the fire approaches enough to felt the air thrust. That is why the trapper did not hurry to be accepted for a job ahead of time, but calmly waited for the right moment. It was worth setting up a little earlier when the counter traction has not yet been established, - and the fire would spread in the opposite direction, making the position of people hopeless. But the delay could be no less fatal: the fire would have come too closely.
