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 automatic gas supply control system;
• 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.

For operation on natural or liquefied gas. Gas burners are available in various technical categories, up to fully automatic microprocessor control. They have from one to several stages of operation and operate at different gas pressures in the line. Low level noise, economical operation, automatic control- these are the main advantages of operating a burner on natural gas. Like all technical devices, the gas burner requires periodic Maintenance and repairs, which can be carried out based on the table below of the main faults gas burners.

Who cares? video review of gas TORCH burners WS-502C

Portable gas burners are very popular both at home and in professional repairs. 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 high fire safety at sites where heavy equipment does not work 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 work, but it perfectly heats 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. The splashing of liquefied gas does not have a significant effect in burners over 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. High temperatures also allow for better quenching 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 its low boiling point, which makes 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 even for rough work may be important.

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.
