Gas burners are one of the main parts of fuel boilers. They are used to burn fuel directly, and their failure has a very detrimental effect on the heating process. Or rather, it disables the entire system. A timely service inspection of the device would help avoid this, but it is not available to everyone. And in this case, the repair of gas burners offered by our company will come in handy.

What can cause the failure of one of the most important parts of a fuel boiler? There may be several reasons, and the most common is irregular technical inspection. Failure to identify problems in a timely manner entails the need for repairs. diesel burners. In addition, this causes a violation of the optimal operating mode of the device, a decrease in efficiency and an increase in thermal loads.

Of course, many owners of fuel boilers would like to avoid such consequences, which means that regular technical inspections become really necessary. Without it, it will be difficult to imagine the trouble-free functioning of the main element of the fuel boiler, but with it it will no longer be inevitable urgent repairs burners

But this is far from the only reason for equipment failure, which is sometimes difficult to understand without a specialist. The cause of the breakdown may also be incorrect use of the fuel boiler, which completely crosses out all operating rules. Careless use of the device will inevitably lead to the need to replace any parts and repair gas burners.

And do not forget that contamination of fuel boiler parts can also cause an early breakdown. Timely maintenance, which will include cleaning, will again help to avoid such an outcome. But many people don’t take this into account and hardly know how to avoid a breakdown, hoping that it will simply bypass it. Then renovation work will be inevitable, and it is better to produce them in a company that knows what it is doing.

Burner repair by professionals

In our company you can order an employee to visit the site of the breakdown. And we will give you confidence that all work will be carried out by specialists and not by amateurs. Our masters have many years of experience, and therefore they repair diesel burners not only within an acceptable time frame, but also in such a way that you do not have to turn to professionals for help too often.

But someone might think that it would be easier to buy new equipment rather than carry out repair work. But in reality it will be more difficult and costly. To purchase this or that equipment, you need to find exactly the model you need. And such searches can take a decent amount of time. So why waste it practically in vain?..

And if a model similar to the previous one cannot be found, then someone decides to offer to buy completely different equipment. But you will need to get used to using a new fuel boiler, which will also take time. So why break the usual routine when, instead, you can repair failed gas burners through specialists?..

It will be more a good decision, which will save you a lot of time. In addition, this way you will significantly reduce your costs. Yes, since a malfunction has already been discovered, it will be easier to fix it. But replacing the entire equipment is worth it big money, and in comparison with this, repairing burners will be a very cheap pleasure.

Portable for both home and professional repairs gas-burners very popular. The scope of their application is very wide, and there are several varieties. You can choose the right burner for your current tasks and learn how to use it correctly by studying this article.

Main types of portable burners

Gas burners in the form of nozzles for cylinders with a collet connection must be considered as a separate class of tools. They are used in conditions of high fire safety at sites where heavy equipment does not operate. construction equipment and the risk of damage to the burner itself is minimal.

First of all, burners are characterized by temperature and flame shape. Most simple devices have a combustion temperature close to the minimum, only 700-1000 °C. Air enters the burner naturally, so it is always in short supply. At the same time, more expensive products have a special shape of air supply channels, due to this the air flow increases and the combustion temperature rises to 1200 °C.

Even hotter flames are produced by ejector-type burners, in which air flows to the hearth due to rarefaction, the flow force is directly proportional to the operating gas pressure. This allows you to raise the temperature to 1500-1600 °C and regulate it relatively smoothly along with the flame length with a simple twist tap. There may be several sources of combustion in the burner; such a tool is not intended for fine workmanship, but perfectly warms up large areas.

The highest combustion temperature for burners is 2000-2400 °C and is achieved through the concentration of injected air in the combustion zone and the use of a special gas: methyl acetylene propadiene (MAPP). A high-temperature cone is formed in the torch flame, comparable in power and temperature to gas-oxygen welding, but not capable of autogenous cutting.

Optionally for all types of burners it is possible to have a flexible or rotary tube, piezo ignition and a highly sensitive control valve. Over a large temperature range there is the same wide choose burners in terms of power and corresponding gas flow.

Tourist burners

Low temperature burners solve a truly wide range of problems and are suitable for household use and professional construction. These blowtorches are most often used to replace electric hair dryers in places where only autonomous operation is possible.

The main disadvantage of burners without an injector is low flame stability, which is especially noticeable during sharp turns and tilts. splashing liquefied gas do not have a significant effect in burners anymore expensive class with a special gearbox and heating circuit.

As a rule, such torches are not used for soldering. Their main purpose is to ignite wood and coals or heat materials that can be used with an open flame. Such a tool is also indispensable for thawing pipes, heating car engines or unpacking tow strips, burning paint to remove it and other rough work.

Supercharged blowtorches

Ejector blowtorches have a more specific device and purpose. These are constant assistants of many designers and craftsmen in the processing of non-ferrous metals. The high temperature and adjustable flame make the torches ideal for soldering and hardening metals or other heat treatments that require high accuracy temperatures and a clearly defined cone.

Due to the specific application, the size of the burners and nozzles may vary greatly. Miniature ones are used for soldering jewelry and thin metal, despite the lack of pure oxygen supply, they can even cope with filigree work. Middle class burners have a cone thickness from 3 to 9 mm and the best way suitable for electrical soldering of connecting wires cable joints, copper and aluminum tubes.

Due to their high power, larger burners can be rationally used in industries such as artistic forging, precision bending or stamping of metal. These are the tools that home craftsmen use as the basis for homemade gas forges and hardening furnaces.

For ejector burners, the concept of an unstable flame is purely figurative, and although periodic flashes of gas are possible, the temperature in the core remains relatively stable. The gas preheating circuit is used more to improve the efficiency of the burners, to reach operating power faster and to accurately regulate the temperature.

High temperature gas burners

We cannot ignore burners that use MAPP gas instead of a propane-butane mixture. The flame combustion temperature in them is 2200-2400 °C, while the main energy is concentrated in a cone, which is quite stable and has a pronounced boundary.

Such burners are used for heating, forging and bending high-carbon steels and massive parts. Heat It also allows for better hardening and tempering of metal.

In terms of soldering and welding, MAPP gas torches do an excellent job of stainless steel, while even thin parts do not overheat. Another advantage of MAPP gas is low temperature boiling, making it possible to use it at temperatures as low as -20 °C even in burners without a heating circuit.

Choosing the best option

Choosing a gas burner for various tasks, you should pay attention to certain nuances. For tourist purposes, the simplest torch burners without pressurization are well suited. Even cheap Chinese products can handle lighting a fire or heating food; you don’t mind breaking or losing them at all.

For household purposes and minor repairs, it is better not to purchase tools from the amateur series. Slightly more expensive semi-professional burners have a more thoughtful design and are devoid of such non-obvious shortcomings as, for example, melting of the plastic lining of the mouthpiece or malfunctioning piezo ignition. Another argument against the average price category is the almost universal absence of a normal control valve, which can be important even for rough work.

If the torch is selected for fine work, soldering or welding, additional attention should be paid to ergonomics and balancing. During such work, the burner has to be turned on and off frequently, so the shape of the body and the placement of the controls should allow ignition and precise adjustment with one hand.

When choosing power, you should be guided by the thickness and material of the parts being processed. A 500-700 W burner will be quite enough for burning paint or soldering copper wires. Tubes made of non-ferrous metals and steel products up to 3 mm thick will warm up well with a flame power of about 1200-1500 W. 2-3 kW burners are used for heating and bending reinforcement up to 14 mm thick. There is one more feature: the flame of powerful high-quality burners can be adjusted for more delicate work, but it will not be possible to heat a massive part with a low-power burner.

Typically, a typical gas furnace has a cast iron burner, a fan, a firebox, and a variety of control equipment.

Purpose of a home gas stove

Gas oven with forced submission air (blowing) to the burners drives air through the heat exchanger using a blower fan. The heat exchanger is heated by gas burners, and warm air goes to the boxes, from where it enters the room.

Diagram of a typical gas stove for a private home. Essential elements:

• blower and system automatic control gas supply;
• burner access panel;
• main gas valve;
• pilot burner;
• main burner;
• control cabinet;
• air filter;
• fan and motor access panel;
• chimney;
• openings for supplying warm air;
• heat exchanger;
• fan motor and fan itself.

The gas pipeline leading to the furnace has a valve that can be used to manually shut off the gas supply. If the tap handle is parallel to the gas pipe, then the valve is open. To shut off the gas, it must be installed perpendicular to the pipe.

Features of the standard manual gas tap:

• the main gas line for the furnace goes up;
• when the handle is perpendicular to the pipe, the gas supply stops;
• at parallel arrangement gas handles are supplied without restrictions.

The gas supply level is regulated by a gas reducer and an automatic regulator. The gas reducer automatically regulates the pressure and, depending on the situation, can increase or decrease it to the level required for work. The automatic regulator is responsible for controlling the gas supply to the burner. In the majority modern stoves these devices are combined into one common fuel consumption control unit. Don't even think about trying to adjust the gas pressure yourself. This should be done by gas company specialists.

Service work on gas furnaces and other gas-powered equipment is much more dangerous similar works, say, with electrical appliances or devices running on fuel oil. After all, even the smallest gas leak can lead to irreparable consequences. If you have even a shadow of doubt about the serviceability of your gas appliance, contact your service provider. gas company or your equipment manufacturer.

Pilot burner

The pilot burner is responsible for automatically igniting the gas burner. It is triggered when the room thermostat sends a signal to it, detecting a drop in the room temperature below a predetermined value. It increases the flow of gas to the control burner.

Burner structure

The pilot burner consists of a jet and a thermocouple. Gas enters the nozzle and burns constantly. The thermocouple is a safety device that is located near the nozzle. The burning flame from the nozzle heats the thermocouple, which in turn opens the valve on the gas line with an electric current.

When the required temperature in the room is reached, the thermostat stops sending a signal to the nozzle and its flame begins to fade. The thermocouple begins to cool and stops supplying electricity to the damper, which as a result closes, thereby cutting off the flow of gas from the line to the nozzle and the main burner.

Operating principle of the pilot burner:

• the burner jet produces a flame;
• the flame heats a thermocouple connected to the damper;
• the jets are attached to the mounting bracket;
• The gas pipeline supplies gas to the control burner.

Pilot burners with electric ignition are also available. The gas in them is ignited using an electric spark. When the gas furnace turns off, the main and pilot burners go out. In some burner devices, the gas is ignited by a hot spiral through which it is passed electricity. When the pilot burner gas ignites, its flame closes the electrical contacts, which open the damper on the main gas line and gas begins to flow to the main burner.

Ignition of the pilot burner

Today there are many models of continuous combustion pilot burners. Find out what kind of pilot burner your furnace has. To do this, carefully inspect it and study the manufacturer’s operating instructions.

As a rule, most modern furnaces are equipped with pilot burners with a combined automatic reducer and regulator. If you need to light such a pilot burner, remove the outer panel and check that the regulator is closed and the power supply is turned off. If you smell gas, wait a few minutes for the area behind the panel to ventilate. If the gas does not clear, call your gas service immediately.

Next, set the thermostat to the lowest position and remove the cover from the burners. The control knob must be turned with the arrow towards the inscription “pilot burner” and by pressing it, bring the burning match to the nozzle. The gas should ignite instantly. Do not release the control knob until the thermocouple is sufficiently hot.

After this, the handle can be released and the lid returned to its place. Then set the arrow knob to the “on” position and turn it on in the oven electrical circuit. Next, return the panel and closing control devices. The thermostat must be set high enough to turn on the main burner.

Standard reducer-regulator and its main components:

• gas main;
• reducer-regulator;
• handle for ignition control;
• thermocouple case;
• use the handle to supply gas to the nozzle, then the gas is ignited with a match;
• flame adjustment screw;
• gas line to the jet;
• gas line to the main burner;
• thermocouple;
• jet.

If you are unable to light the pilot the first time, try again after waiting a while for the gas from the previous attempt to clear. If the second attempt is unsuccessful, this is not good and most likely the problem is not in your hands, but in the burner. It is recommended to contact your gas service. Most likely the thermocouple is faulty and needs to be replaced.

These gas stoves are very often used in modern baths.

In older models of furnaces, the gearbox and regulator are separate. The ignition procedure is basically the same as modern models, but there are slight differences. It consists in the fact that to ignite the burner, you first need to open the gas supply using the gas valve handle, and then press the constant-burning burner control button, which is often painted red, and bring a burning match to the nozzle. Do not release the red button until the flame heats the thermocouple sufficiently. This usually takes about a minute.

Adjusting the flame in the pilot burner

To determine the location of the screw responsible for regulating the flow of gas into the burner, study the manufacturer’s operating instructions. It is very important that the flame is of the required intensity. After all, if there is too little heat, the thermocouple will not heat up, and when you release the button, the burner will immediately go out. And if the flame, on the contrary, is too large, then the thermocouple will fail faster than usual.

If you still cannot light the burner, the reason may be that the torch is too small or the nozzle is dirty. Try cleaning it with a wood chip or toothpick and removing dirt with a soft brush or cotton swab. You can also use a vacuum cleaner for this purpose.

The pilot burner nozzle can be cleaned with a regular soft toothpick and brush.

Techniques for servicing a gas burner

A gas burner, like any equipment, needs cleaning from time to time. after-sales service. However, today many codes technical work It is strictly prohibited to intervene independently in work and repairs. gas appliances and devices. Therefore, it is often necessary to resort to the services of professional specialists.

However, this fact cannot prevent us from reviewing some valid preventative procedures that can significantly improve the efficiency of your gas burner.

Cleaning the firebox

Make sure that inner space the fireboxes, burner, and control equipment were kept clean. Periodically vacuum the firebox and clean the control equipment from dust.

Vacuum both the column and the burner itself from dust. The jets are cleaned with a brush.

Engines with lubrication points must be lubricated with a small amount of oil.

Shutting off the gas main tap

Always at the end heating season When there is no longer any need to operate the stove, turn off the gas main valve.

The handle of a closed tap should be perpendicular to gas pipe. If your gas is in a cylinder, close the shut-off valve on it.

Finding leaks

Be sure to check pipes and equipment for gas leaks. The location of the leak can be found by smell. Special substances are added to the gas entering your home, which gives it a characteristic pungent odor.

If there is a leak, turn off the gas valve and immediately call the gas service.

Examine the torch flames

At the beginning of the heating season, when you start the furnace, look at appearance flame torch. It should be blue-green in color.

Check the color of the torch in the burner.

If there is something wrong with the torch, call a technician who will adjust the supply of the gas-air mixture correctly. The pilot burner flame length should be 13 mm. It can be adjusted using a screw.

Joint density

Be sure to check the tightness of the chimney joints and the presence of holes in it. Those sections that have holes need to be replaced.

To check the pressure regulator, main gas valve and safety valve Call a professional every few years. To determine the efficiency of a gas furnace, the technician must also check the draft, the temperature of the exhaust gases and the level of carbon dioxide in them.

Free-standing gas heating stoves (fireplaces)

These gas stoves have a very similar appearance to wood stoves. The chimney design of both stoves is also approximately the same. Modern models gas furnaces are highly efficient heating equipment, which produces a large number of heat.

A free-standing gas fireplace is a real addition to any interior.

The burners in such stoves look like burning logs, which can be seen through the transparent door. When purchasing such a stove, you should also be provided with instructions for installing it, as well as an operating manual. The outlet pipe is routed in the same way as the pipe in wood stoves, i.e. into an existing one in the house brick pipe, fireplace chimney, wall and roof.

The heating gas fireplace fits perfectly into the Victorian style.

For gas stoves there are also established requirements for their location relative to the floor and walls of the room. Despite the fact that wood and gas stoves are subject to the following requirements in the code: different requirements, their smoke exhaust systems are similar to those shown in the diagrams above.

A gas stove of this design can stand right in the middle of the room and will not disturb anyone.

The free-standing gas stove harmonizes perfectly with the white design of the room.

The wall-mounted gas fireplace, unique in its design, will not leave anyone indifferent.

Simple free-standing gas fireplaces with a minimalistic feel.

Free-standing gas stoves are similar to those used in , equipped with a pilot burner and ignited in a similar manner. Accordingly, exactly the same safety rules apply to it.

However, in any case, follow the rules prescribed in the manufacturer's instructions. If the pilot burner does not light for more than five seconds when igniting the oven, turn off the oven, ventilate any accumulated gas, and try again. If you don’t succeed the second time, call the supplier’s representative.

Repair gas stove DIY is prohibited by Russian law. True, criminal liability is not yet provided for; if an accident occurs, troubles are expected. In the hero city of Volgograd, one smart guy started a vent water heater combustion products. 4 people died. The authorities classified the case based on the article causing death by negligence. Gas service technicians have the right to replace equipment and perform service work. This is relevant, starting with connections and ending with switching to a different type of fuel. Below are a couple of recommendations, not a user manual, just general techniques.

Installation of a gas stove with electric ignition

Darina, Hansa, Ardo – so different and at the same time the same. The repair of gas stoves by Hephaestus is exactly like the repair of Ariston; gas stoves are made up of standard units. It is enough to look at a single device to understand the circuit. Have a reference book to help you properly maintain gas pressure. When set correctly, the flame is even and blue. Orange flashes indicate an imbalance in the fuel mixture. If the settings are incorrect, the flame will fail (especially typical for carob ovens).

Those who have read the reviews of the VashTekhnik portal regarding gas instantaneous water heaters, do-it-yourself repair gas stoves will seem like child's play! You cannot do it yourself, but you can clean the device. The technician will have to clean candles, combustion sensors, burners, and sometimes nozzles. There are a lot of interesting things inside the gas stove. To the master proper cleaning equipment, you should understand what you will see inside. Under the gas stove table:

• Burners. They are often bolted to the gas stove table. Each burner consists of a lid, a divider, and an injector (nozzle). They are not rigidly fastened under the table; each is fitted with a steel or copper tube; the fastening is carried out like an American one. You will need a key of approximately 13 to remove the products. It is more convenient to clean if something is clogged inside. Beware of tearing off the head or thread - you will have to replace it. After assembly, check the tightness by washing. The procedure involves applying foam to the disputed nodes.
• There are two candles around the perimeter of the burner. One serves as ignition (due to a piezoelectric element or an electronic circuit), the second is a thermocouple, included in the combustion control circuit. It's quite easy to distinguish. The high-voltage spark plug is covered with a ceramic caftan so that the spark does not strike below a predetermined level. When the arc flows, you can see: the tongue of the discharge licks the body of the burner. Gas stoves with electric ignition will be properly grounded by a technician. Beware of using plumbing connections or connectors pierced with metal threads. During installation, the hoses are separated from the riser by special gaskets. Failure to follow the rule will easily provoke an explosion in favorable situations. We wrote in more detail, we remind you again. The candle with a thermocouple is covered with a bronze caftan that conducts heat. The faster the semiconductors cool down, the flame goes out, and the protection that cuts off the gas supply will work more reliably.

• Most often there is a collector under the table. A thick tube from which a line goes to any burner. The gas flow is controlled by solenoid valves. The number is usually equal to the number of burners. When the burner flame goes out, the rest will burn. The expediency of the decision can be challenged, but this is how it is done. Each solenoid valve contains an inductor. The thermocouple heats up, an EMF (tens of millivolts) appears, keeping the devices open. Full order turning on: turn the gas supply regulator, press. We press the piezo ignition button, or the electronic circuit performs a set of procedures independently. We hold the handle for a fixed time. The thermocouple warms up, an EMF begins to be generated, the electromagnetic valve is held open due to the phenomenon discovered by Seebeck. As soon as the gas goes out, the sensor plug cools down and the gas supply stops. The process is inertial, we believe that the day is not far off, flame ionization sensors will begin to be used in gas stoves, allowing the protection to operate instantly.
• Similar to the gas manifold, there is a distribution valve panel inside. Single high-voltage wires run to each ignition electrode. Another way to distinguish a thermocouple: two wires with a thinner cross-section stretch to the sensor. The spark breakdown goes to the housing, the second ignition wire is superfluous. If the gas stove is deprived of grounding, we have a chance of getting an electric shock. Fatalities are possible - an additional reason to entrust the installation to a professional. The collector is connected via connectors. There is protection against incorrect orientation of the plug; you can easily mix up some places. When you open the burner, a spark will jump on another divider. It’s not very pleasant, a flash of flame is possible.

• If a charge is formed electronic circuit, you will find inside a simple thyristor, diode, capacitor, fuses. The circuit operates, powered by a capacitor charge with a subsequent burst of energy from the spark gap of the spark plug. Repair of electric ignition of a gas stove concerns the listed elements. The fault is easy to notice. Burnt elements are black or similar in color.

Setting up a gas stove for a different type of gas

Gas is endowed with two significant characteristics:

1. The calorific value is determined by the composition. The higher the methane content, the lower the parameter. For natural gas, the calorific value is predetermined by the location where the natural resource is extracted.
2. The pressure depends on the type of gas. Liquid requires higher. For the main line, the typical value is 13 mbar. The parameter ensures the correct operation of solenoid valves, injectors, and burners.

When too high blood pressure the gas burns incompletely, soot and orange flames will appear. The system may not operate correctly. I have come across instructions recommending the use of a reducer to obtain 13 mbar from a balloon. There are probably restrictions. It is not without reason that it is recommended to place two cylinders in parallel. Please note that the main gas is actually liquid, supplied through a reducer. It is pumped from tanks into containers from which houses are supplied. Find out the wiring diagram for the house where you live. Occurs natural gas, distributed centrally, having lower cost, pressure, and calorific value. The pressure is assumed to be 13 mbar. This aspect must be taken into account when installing and repairing a gas stove.

The reason to call professionals for installation and configuration is that the specialists know the parameters. Of course, a person with a certificate is also aware of local conditions. Now imagine what will happen if you unknowingly connect the equipment incorrectly! It's a gas, stop joking. This is especially true in the outback, where neighboring houses may have different connection. It is recommended to purchase a set of replacement injectors for different gas pressures. They described the process of boring jets with their own hands and mentioned that the law prohibits rework. The work is unsafe. Before purchasing, ask your gas service for the parameters and ask the store if the equipment is suitable. It’s not too late to start making inquiries during the next cleaning. It's not a fact that everything was done correctly.

How to adjust jets. The size of the central hole changes. Less pressure, the hole becomes larger. Verticality and alignment must be maintained, otherwise gas will leak to the side, which will lead to an accident. It is appropriate to recall that in old Soviet gas stoves the jets are hidden deep inside. The design of the burners is unusual. Between the nozzle and the divider there is a tube with a pair of ears attached to the frame. There is one frame for every two burners. In pairs, the pipes are attached with ears inside the housing. A bowl with a nozzle is placed at the lower end, and a divider is inserted into the upper end. The gas stove operates using a jet stream. Propane-butane is heavier than air.

The peculiarity is that opposite the nozzle there is a tube with a radial cutout. Needed to unscrew the hex nozzle without using a long socket wrench. In modern gas stoves, the jet is located under the flame. A different arrangement improves traction and discourages ordinary people from climbing inside the stove. Repairing a gas stove with your own hands is a dangerous business.

Electric stoves today also look like a more appropriate option for summer residents.
