As part of this material, a gas burner device of the AGU-11.6 model with a standard set of automation and control and safety equipment 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.
Appointment
The gas burner under consideration AGU-11.6 is intended for the repair and modernization of outdated individual household boilers. That is, if for some reason the gas combustion system is out of order and it is urgently necessary to restore its operability, then you can install such a burner. Again, it is first necessary to clarify the compatibility of the boiler and ASU-11.6.
Also, such a gas combustion system is used by default in some models of modern domestic boilers. One of these is AOGV-11.6. Its key feature is that it is equipped with two heating medium circuits. One of them is designed for heating and is used in the cold season, and the second is used for heating water year-round.
Types of burner devices
Any modern gas burner device according to the method of supplying air can belong to one of two groups. The first of them 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 ASU-11.6. The second group is based on forced air supply, and the 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 recommended that those boilers are equipped with burners with forced ventilation and have improved technical and economic indicators. Moreover, the cost between the first and second group is not so much different.
Main characteristics
The automatic gas burner modification AGU-11.6 has the following main technical specifications:
- The nominal value of thermal power corresponds to 11.6 kW.
- The type of gaseous fuel used is natural gas.
- The nominal pressure of the supplied fuel is 1.3 kPa.
- The optimal range for temperature control is 50-90 ° C.
- Recommended dimensions of the furnace are 200 × 240 × 310 mm.
- The internal diameter of the nozzle for connection to the gas pipeline is 15 mm, and the thread on it is G1 / 2.
- The declared mass of the device is 6.3 kg.
- Recommended lifetime is 15 years.
- Warranty obligations are provided for 2 years from the date of purchase of the fuel combustion system.
Automation Overview
Automation of gas burner devices of the AGU series has the following safety loops:
- Flame control is carried out using a heating plate. If the temperature exceeds the permissible limits, the shut-off valve automatically closes.
- In the absence of traction, a miniature mechanical relay blocks the unit from starting.
- If the gas pressure exceeds the permissible limits, then the corresponding sensor suspends the operation of the heating system.
- The temperature control of the carrier is implemented manually using the appropriate gearbox.
Launch order
The AGU-11.6 burner, complete with a standard set of safety and control automation equipment, starts as follows:
- The first step is to check for natural traction.
- Next, the stop valves of the igniter are opened, and it is manually ignited.
- Then it is necessary to wait about 60 seconds until the shut-off plate of the main burner valve warms up.
- After that, gently open the ball valve of the main burner, which should be ignited.
- In the future, it is necessary to wait 10-15 minutes to warm the boiler furnace. It is also recommended at this stage to open the circulation of the medium in the heating system.
- Upon completion of the heating phase, it is necessary to adjust the gas supply and achieve the required water temperature at the outlet of the boiler.
Cost
At the moment, 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 retail outlets ASU-11.6 with a guarantee you can buy for 5700-6000 rubles. Again, in the first case, delivery costs must be added to the cost of the burner. However, warranty is not always possible to provide. Therefore, it is recommended that AGU-11.6 and other similar devices be purchased at specialized retail outlets.
Reviews Relevance
The gas burner device under consideration with the AGU-11.6 marking has one significant drawback - this is an increased gas flow rate, which is explained by the presence of an injection method for supplying air. The advantages include system reliability, low cost, the availability of automation and versatility. As noted earlier, such a burner is not recommended for use 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, but from an economic point of view, its use at the moment is impractical for the reason that the gas consumption is too high. The rest is a reliable and time-tested solution.
