Within the framework of this material, a gas burner device of the AGU-11, 6 model with a standard set of control and safety automation tools will be considered. The main technical parameters of this solution and the algorithm for its launch will be indicated. In addition to this, the material shows the cost of this component of individual heating systems, its strengths and weaknesses are considered.

Destination

The considered gas burner device AGU-11, 6 is intended for repair and modernization of obsolete individual household boilers. That is, if for some reason the gas combustion system is out of order and you need to urgently restore its performance, then you can install such a burner. Again, it is first necessary to clarify the compatibility of the boiler and AGU-11, 6.

Also, such a gas combustion system is used by default in some models of moderndomestic boilers. One of these is AOGV-11, 6. Its key feature is that it is equipped with two coolant heating circuits. One of them is designed for heating and is used in the cold season, and the second is used for heating water all year round.

Types of burners

Any modern gas-burning device according to the method of supplying air can belong to one of two groups. The first one is called injection. In this case, there is no ventilation unit, and the air supply is realized due to the special design of the burner in a natural way. It is this principle that is implemented in AGU-11, 6. The second group is based on forced air supply, and a fan is included in the burner without fail.

As the operating experience of recent years has shown, it is no longer economically feasible to use injection systems for burning gaseous fuels. They have low efficiency and increased consumption of natural gas. Therefore, in most cases, when modernizing heating systems, it is those boilers that are equipped with forced ventilation burners and have improved technical and economic indicators that are recommended. At the same time, the cost between the first and second groups is not so much different.

Key Features

Automatic gas burner modification AGU-11, 6 has the following main technical specifications:

1. The rated heat output is 11.6 kW.
2. Typegaseous fuel used is natural gas.
3. Nominal fuel supply pressure is 1.3 kPa.
4. Optimal range for temperature control is 50-90°C.
5. Recommended firebox dimensions are 200 × 240 × 310 mm.
6. The inner diameter of the fitting for connecting to the gas pipeline is 15 mm, and the thread on it is G1/2.
7. The declared mass of the device is 6.3 kg.
8. Recommended service life is 15 years.
9. Warranty is provided for 2 years from the date of purchase of the combustion system.

Overview of automation

Automation of gas burners of the AGU series has the following safety circuits:

1. Flame control is carried out using a heating plate. If the temperature is out of range, the shut-off valve will automatically close.
2. In the absence of thrust, a miniature mechanical relay blocks the unit from starting.
3. If the gas pressure is out of range, the corresponding sensor stops the heating system.
4. Regulation of the media temperature is implemented manually using the appropriate reducer.

Start order

The AGU-11, 6 burner, complete with a standard set of safety and control automation, is started as follows:

1. The first step is to check for natural draft.
2. Next, the shut-off valve of the igniter opens, and it manuallyset on fire.
3. Then wait about 60 seconds until the main burner valve shut-off plate warms up.
4. After that, smoothly open the ball valve of the main burner, which should ignite.
5. In the future, you must wait 10-15 minutes to warm up the boiler furnace. It is also recommended at this stage to open the circulation of the carrier in the heating system.
6. After the warm-up phase is over, adjust the gas supply and achieve the required water temperature at the outlet of the boiler.

Cost

Currently, such gas burner devices for boilers can be purchased for 5000-6000 rubles. Moreover, if you choose on the Internet, the price will be lower, and if you wish, you can purchase such a solution even for 4700-4800 rubles. Well, in specialized outlets AGU-11, 6 with a guarantee can be bought for 5700-6000 rubles. Again, in the first case, shipping costs must be added to the cost of the burner. At the same time, it is not always possible to provide warranty obligations. Therefore, it is recommended that AGU-11, 6 and other similar devices be purchased at specialized outlets.

Reviews. Relevance

The considered gas burner device marked AGU-11, 6 has one significant drawback - this is an increased gas consumption, which is explained by the presence of an injection method of supplying air. The advantages include the reliability of the system, low cost, the availability of automation and versatility. As notedearlier, such a burner is not recommended today due to low technical and economic characteristics.

Conclusion

As part of this review, a gas burner device of the AGU-11, 6 model was considered. Although such a fuel combustion system is used in modern boilers, from an economic point of view, its use is currently impractical due to the fact that gas consumption is overestimated. Otherwise, this is a reliable and time-tested solution.
