Gas burners for boilers: design features

Gas burners for boilers provide burning fuel to generate heat energy. In fact, these products, together with the heat exchanger are the main part of the unit, operating on gas. design simplicity does not negate their versatility and functionality. It is important to have an idea about the structure of the boiler burner to select the time of purchase heating equipment correctly.

What is the gas burner and which consists of

Any device designed for burning liquid and gaseous fuels, there is the main node - a burner. It is responsible for forming uniform flame. The fuel mixture can be of varying quality, but well-designed fuel supply method will ensure complete combustion of any combustible mixture.

The most important indicators of quality device for burning gas - noiseless operation and lack of harmful compounds from fuel combustion, in particular carbon monoxide. Modern household gas burner for heating the boiler - a simple device elapsed long upgrading process. Some older designs produced in the Soviet era, published a lot of noise and were not safe, especially in high winds.

For many parameters, including noise, affecting the design features of the combustion chambers. The new burners samples a lot of attention is paid to ease of ignition and even feed the flame. Structural features of a gas burner for heating is very simple:

• ignition gas ignition system is provided;
• gas is ignited at the nozzle;
• equipment designed to control the main parameters: temperature uniformity of gas distribution, emergency shutdown;
• the presence of fire is controlled by a special "flame detector".

Gas from the room side of the combustion products to be output to the outside, so that contaminants are not filled space. Degassing chimney required having good traction. This is the only disadvantage of gas heating. Needless gas burner device is constantly being improved, including the following figures:

• circuits generate heat;
• rational flow of oxygen;
• methods of exhaust soot and carbon dioxide.

Gas burners for boilers: basic requirements and work scheme

The heat released during combustion gas is concentrated in the heat exchanger, where the coolant is transferred to. Together with a small amount of heat output portion of the combustion products into the atmosphere. A chemical heat release reaction: burning at a high temperature gas is combined with oxygen coming from air. On combustion of gas and heat dissipation principle construction of the gas burner. Water vapor and carbon dioxide - by-products of the chemical reaction related to the receipt of heat.

Among the hazardous substances called nitric oxide, carbon dioxide and some resinous components. Because of this, there are special requirements to the hood and chimney - important good traction.

According to modern requirements in any mode of gas burners for heating boilers with automatic (and other species) have different low toxicity. It is required that only slightly toxic gases and a small amount of soot emitted during combustion, which is a common condition for the application of most raw materials for heating.

Basic requirements for the boiler to the burner:

• accessibility for self-installation;
• clear circuit design;
• an extended period of operation;
• operational reliability;
• slight noise threshold;
• ease of switching modes;
• possibility of working on a different type of fuel;
• complete combustion gas;
• high environmental indicators (indicated little harmful combustion products).

Useful advice!To prolong the life of the equipment, carrying out timely repair of a gas burner for the boiler, it is important to acquire the components only from trusted manufacturers.

As you know, cheap goods indicates low quality products and short term operation. Often, the repair is not possible, especially if there is no warranty and factory certificate. On sale there are always high-quality household gas burners for heating boilers. Their price is quite acceptable to most consumers.

The basic types and classification gas burners

An extended period of sale did not have much abundance of this type of product. The simplest boilers, gas water heaters, and the Titans were in short supply. The appearance of the gas burner of the boiler with control regarded as something fantastic. But these devices also required ventilation with full chimney. Currently offered even mobile infrared burners for a picnic, running on gas.

Modern fuel assemblies are very diverse. Their advantage - virtually complete combustion of the fuel and no release of toxic impurities when operating in closed conditions.

Traditional heating equipment different structural variability:

• atmospheric boilers;
• universal;
• Low temperature;
• turbo;
• fan;
• injection;
• pezopodzhigom with gas burners.

Devices made with their own hands - is also not uncommon. Homemade gas burner can be assembled using drawings, diagrams and sketches of artists, containing detailed descriptions, as well as viewing the video.

Boilers are of different types of flame ignition - Using Piezo lighters and by a spark when activated electronics.

It is important!Pezopodzhigom - single ignition, after which the flame is maintained in the operating mode as long as there is a gas supply. The device should not be confused with a burner for gas cookers (with the nozzle divider) and the grill.

Electronic ignition must operate during startup supply valve: gas ignited by electrostatic spark. This embodiment is considered the most economical and reliable, but with interruptions of electricity supply boiler often idle (if there is no alternative way to ensure its inclusion).

Gas burners with pezopodzhigom and other methods for maintaining the flame

A variety of burners is determined by a number of features, including air injection method and design features of the furnace itself, which may be:

• open (from the heated air enters the room, ventilation is needed, the combustion products are discharged into a chimney);
• gated.

Low temperature gas burner (atmospheric) is preferably used in open furnaces. They have a simple device and debugged operating principle. The gas supply to the wick is carried by the ejector. Thus the air flows directly from the boiler, wherein heating equipment is installed. When the low-temperature ignition visible tabs small flame.

This kind of gas burner for furnaces and boilers has a low noise level, availability, and versatility. Such a device can be adapted to the furnace on the combined fuel modern equipment profile and primitive boilers old sample.

The principle of operation of the gas burner with pezopodzhigom is quite simple, especially if the parameters of the heating circuit set. The sensor captures the temperature decrease triggered the stop-valve and ignition. Blue fuel entering the burner is ignited, releasing heat.

Control of the flame in the gas facility occurs differently. In some units, it looks very primitive, others are equipped with electronics. Sometimes complex circuits are used, even when the old equipment upgrades using a gas burner to the boiler with his hands.

Attention!If a low-cost burner, then, in all probability, it is composed of a simple thermocouple, which will require fast replacement.

Advanced boilers with a "smart" options are equipped with ionization controller sensitive to changes. This ensures overlap gas in the event that the flame goes out and will not be enough oxygen for the combustion process (run out of fuel).

Electronics is also responsive to an increased concentration of impurities in the blue fuel and combustion byproducts. Gas will be blocked (it is thought in the gas burner SABC) and ventilation starts to operate at full capacity.

Useful advice!Before cleaning the gas burner of the boiler, it is important to understand its structure, studying technical documents containing the description of operation. Each kind of product has the structural differences.

Burners of atmospheric type for boilers and gas burners manual

Work due to the flow of oxygen naturally gives complete fuel combustion, combustion gases through a conventional flue. Operation of the equipment with simplified devices and atmospheric type gas burners special nozzles.

Attention!The only condition the device works on oxygen, which is taken from the heated space - excellent ventilation.

Important advantages of the boiler with gas burners of atmospheric type:

• independence from the power supply, which is important when working in areas without electricity;
• high reliability (no complex parts requiring frequent repairs);
• low noise threshold;
• structural simplicity;
• affordable price.

Important!Information for those who are interested, how much is the simplest sample gas burner - its price starts from 250 rubles. A gas burner value ugop-P-16 "crayon", for example, approximately 1000 r.

The disadvantages of atmospheric units include:

• the need for the full chimney offtake outwardly smoke and fuel slurry;
• relatively low efficiencies (as compared to upgraded samples);
• probability of incomplete combustion of the fuel with a deficiency of oxygen;
• complexity adaptation to other heat sources;
• the need to install ventilation and a small window.

Helpful information!Burners with ignition of electronics involve high voltage converter operating on the network. This is different from simple devices such as a manual gas burner.

Using ejector burners in boilers finished and converted

Combi boiler with a ceramic gas burner justify expenses for its versatility, although it is considered to be an expensive option. Far from the budget the equipment has many advantages, including the autonomous firing:

Types of boilers. Varieties of gas boilers, their features, the replacement and installation. The top 10 gas-fired boilers.

• under the solid fuel;
• with a gas burner.

With this equipment, you can easily switch to coal and wood, with the use of any organic recycle. This is a good opportunity to save on gas, particularly in the private house, where there is always an opportunity to find something for disposal.

To bring the gas burner additionally providing them automatics fired boilers are often equipped with special nozzles or wicks. For this purpose, a simple approach atmospheric burner or ejector (air suction). The whole boiler is not required to alter, as the rest of the functions on the same principle: fuel combustion is performed to generate heat energy for heating coolant.

Useful advice!For the old domestic equipment more suitable for the type of atmospheric gas burner, because a complete seal in them can not be achieved due to the design specifics.

Equipment for automatically providing combustion process combined boilers can be purchased additionally, if required convert the wood-burning furnace in a gas boiler. Some models are solid fuel boilers, including pyrolysis, equipped with a gas burner whose flame is necessary for ignition.

Fan or inflatable burner with forced air

The furnace has some devices mounted fan (air blower). Its function - to ensure compulsory ignition chamber with oxygen. In this case, oxygen supply is forcibly volume is automatically controlled.

This need is gated cameras where there is no free access of air mixture that creates the conditions for a high temperature gas burner. Lack of natural access compensated by a simple adaptation of the fan type.

Such burners have their "pros" and "cons." But they are not as versatile as it is necessary to use artificial injection, which requires additional energy consumption. An important advantage - the fan unit is fully adapted to the automation of the boiler. In these models, a mixture of fuel and oxygen is obtained directly at the output.

Multiblock gas burners for heating the transport air by the fan have the following structure:

• fan relay which disables the burner at a stop engine blades;
• a pressure regulator;
• block filter;
• OFF / ON of the burner valve (changing the pressure);
• Fuel option;
• reducer;
• bespereboynik (needed in case of sudden electricity outage, but it is not available in all devices).

Note!Inflatable or fan burners are often part of the boiler room equipment with a fairly high threshold of automation that is necessary in order to avoid serious accidents.

The servo drive monitors the position of the damper, so there is no need to adjust the burner and further monitor the work of the boiler. Regulation portions incoming oxygen required for complete combustion, occurs automatically.

A significant disadvantage of this type of gas burner - price, due to the complex product design.

Gas burners are not suitable for the "DIY", especially in the case when they want to remake the solid fuel boiler under the universal unit, and it requires a good heat insulation. Burners are volatile, often they are equipped with redundant power supply.

The general classification of gas burners for fuel type

Vacation homes is not always possible to provide the natural gas supplied from the common rail. Therefore, the variability of burners is provided in terms of using different types of fuel. If the fuel is supplied from the gas line is likely to apply propane-butane gas burner for heating boilers.

Bulk methane gas - the most available natural fuel for boilers. Now, however, there is not much benefit in the price of liquefied natural gas (propane-butane mixture). Total heating, provides the main pipeline, too, does not come cheap.

Gas boilers operating on different types of fuel mixtures, are approximately the same design. There is a small difference in cost, but it is also negligible (Liquefied fuel equipment will be more expensive). Burners themselves are slightly different, with different nozzles a liquid fuel and blue gas.

Propane burners require configuration for this type of fuel with the installation of the nozzle. In combustion flame lights give a yellowish color, a chimney soot accumulates over. Jet is responsible for normalization of pressure.

Modern burners operate over a large temperature range - from -50 to +50 ° C. Part of the equipment can be adapted for other forms of energy:

• waste oil;
• diesel fuel;
• oil;
• kerosene;
• propane-butane basis;
• Arctic diesel fuel.

Modern devices are often included both types of nozzles or multi-purpose equipment under the fuel species, thereby easily reconfigured.

Attention!Some craftsmen offer gas burners for boilers with their hands (a solid-equipment).

It is safer to buy a simple gas equipment adapted for gas in cylinders. Improvised equipment even more affordable, but unsafe! It is usually carried out "alterations" on the basis of the old units.

Turbocharged types of gas burners and their structural differences

Among modern gas equipment, many experts prefer gated turbo burners for boilers. They are self-sufficient in a constructive manner, assume a compact chimney, which can be taken away, even in the general ventilation when heating.

The heating unit with a special combustion chamber gated receives oxygen from the outside - of a special supply pipe (coaxial chimney). Approximately the same outwardly through the products of combustion output. Heating equipment is controlled by means of a powerful fan to automatic control.

It is interesting!Coaxial chimney - a device designed on the principle of "pipe in pipe". The turbocharged boiler can operate even in a bunker or other sealed room with no windows or ventilation shaft.

Such a device is much more expensive than the atmospheric heating equipment. However, for an additional fee the buyer receives a number of advantages, including autonomous operation in a residential area. This device, thanks to the automatic control, a high level of security ,.

In turbo equipment is the high efficiency and flexible thermal circuit. Fuel is burned almost completely, which is important for environmental performance. Marked and disadvantages, including structural complexity, causing difficulties in the installation and repair.

Gas burners are most often used for cogeneration equipment in solid fuel fired boilers. This is a fairly complex machine, so all nodes must meet certain performance and safety requirements. Automatic device able to switch from one fuel to the other for a continuous supply of heat. According to this principle and arranged pellet pyrolysis boilers equipped with gas burners for actuating the ignition process.

How to choose a gas burner for a furnace or boiler

Gas equipment due to improper operation carries a certain risk. You must select the correct furnace gas burner (nodal details), and you need to have a basic understanding of the structural differences between the devices. When you purchase it is important to know which types of the product divided by the process of fuel combustion in the boiler:

• atmospheric burner;
• inflatable.

Not every manufacturer to be trusted, the purchase is better to carry out official dealers that provide certificates and all technical documentation. In case of purchase of substandard components or nodes will someone make a claim.

Insulating equipment for gas differs different features, the method including the ignition and flame adjustment. When buying, experts recommend pay attention to the following indicators:

• heat generator power;
• demands for the quality of the gas mixture;
• automatic regulation;
• company's reputation and the country of manufacture;
• price-quality ratio".

Burners for floor boilers are offered in such embodiments:

• atmospheric;
• supercharged,
• piezo;
• e.

For power adjustment, you can select the burner:

• 1-step;
• 2-step;
• with a smooth transition;
• with automatic adjustment.

Feed gas mixture in the different boilers is:

• straight-through;
• hooked (more powerful).

The most popular are considered gas burners for boilers German production (Buderus, Vaillant), Slovak (Protherm) and Italian (Lamborghini). Among the products manufactured by domestic companies, it has proved itself "Lemarks" equipment "Vakula" and "Konord". Among industrial devices - "Impulse" series of burners.

The duration and productivity of any machine depends on the correct choice and correct operation. Gas equipment acquired not on the basis, where "less" or "more powerful", and according to the existing boiler type.
