Complete set and advantages of accessories

1. Pig-iron heat exchanger Imar (Italy)
2. Gas automation manufactured by SIT Italy is characterized by stable operation both with fluctuations in gas pressure in the pipeline and at low pressure.
3. To determine the temperature of the heat carrier (water), a capillary thermometer is installed in the glass of the bulb.
4. The chimney with an adjustable draft gap is designed to stabilize the draft and ensure stable operation of the boiler under variable wind loads.
5. The draft control system (draft sensor) of Italian production in the collector of combustion products ensures that the device is turned off in the absence of draft, in order to prevent them from entering the room.
6. This design uses round microtorch burners Polidoro (Italy) or Bray (England), which allow you to evenly distribute the flame over the entire area of ​​the combustion chamber, which ensures fast and uniform heating of water in the heat exchanger.
7. Unit of pilot burner, piezo ignition and thermocouple SIT (Italy). In the design of the AOGV 30 IR, 40 IR, 50 IR, 70 IR, 96 IR models, a direct ignition system is installed instead of the pilot burner unit.
8. The manifold with nozzles provides high efficiency.
9. Window for visual control of the combustion of the main and pilot burners.
10. Gas supply pipe.
11. A glass of thermocylinders of a thermometer and a gas valve.
12. Pressure gauge for measuring the pressure in the heat exchanger.
13. Air vent for removing air from the heat exchanger.
14. The safety valve for lowering the pressure by draining the coolant when the pressure in the heat exchanger rises above 0.3 MPa.
15. Safety thermostat to stop the operation of the boiler in case of overheating or emergency situations.
16. The surfaces of the outer casing of the AOGV are covered with powder paint, which evenly, without sagging and carpets, tightens the surface, adhering tightly to the metal, thereby increasing protective properties such as: corrosion resistance, impact resistance, The surface covered with such paint is easy to clean and wash.

The design of the gas boiler Ross AOGV-16

The single-circuit gas boiler Ross AOGV-16 is designed for heating rooms equipped with water heating systems with treated water. It is used for continuous operation.

The double-circuit unit additionally allows you to provide water heating for household needs.

The principle of operation of the boiler device is based on heating the coolant (water) located in the heat exchanger due to the combustion of gas in the combustion chamber of the apparatus.

The AOGV-16 device works on natural gas GOST 5542-87 with a pressure of 1274 + 100 Pa and automatically maintains the temperature set on the automation unit.

Fig.8. Device gas boiler Ross AOGV-16

The Ross-16 boiler consists of the following parts (Figure 8) described below.

The heat exchanger (1) is an all-welded cylindrical body, in the lower part of which a combustion chamber (6) is made.

Inside the body of the heat exchanger, pipes are welded through which the combustion products pass. Turbulators (7) are installed in the pipes, which increase the efficiency of heat transfer from combustion products to the coolant (water).

In the lower part of the front wall of the heat exchanger, a gas control unit (2) is installed. Branch pipes (11) are used to connect the heat exchanger to the heating system.

In the upper part of the heat exchanger, a cup (9) is welded for installing a gas valve bulb, and a ring (8) for installing a thermometer (10).

The heat exchanger is mounted on a frame (5). In double-circuit models, inside the heat exchanger of the heating circuit, a tubular heat exchanger of the hot water supply circuit is additionally mounted, made of a copper tube or a stainless corrugated hose.

To connect the hot water circuit, pipes (25) are used.

The gas automation unit (2) consists of a gas manifold (12) mounted on a bracket. Plate burners are fixed on the same bracket.

The gas collector (12) is connected to the multifunctional gas valve (14), which regulates the gas supply to the Ross-16 boiler depending on the required operating conditions.

The gas collector has an outlet in which nozzles (15) are installed. The gas supply from the gas pipeline to the gas valve (14) is carried out using an adapter (16).

Each time the apparatus (boiler) is turned on, the burners (13) are ignited by the constantly burning flame of the pilot burner (17).

The multifunctional gas valve (14) ensures that the device (boiler) is turned on and the set mode of its operation is maintained together with the thermocouple (18), draft sensor (20), pilot burner (17) and piezoelectric element (19).

The front door of the appliance must be opened to access the gas valve.

The piezoelectric element (19) is placed directly on the gas valve (14).

The multifunctional gas valve allows:

Turn off both the main and pilot burners - the control knob is in the "point" position;

Light the pilot burner;

Turn on the device (boiler) to work.

A2 - Gas valve EURO SIT 630
SK1 - Draft sensor - thermostat TK24-03-3-60°±3%
XS1, XS2 - Car terminal clamp

When the button of the piezoelectric element (19) is pressed, a spark is generated to ignite the pilot burner (17).

The combustion products collector (3) ends with a neck for connection to the chimney. A draft sensor (20) is installed on the combustion products collector (3).

To clean the heat exchanger, the casing cover of the Ross AOGV-16 boiler is removed, then the combustion products collector (3) is removed.

The outer casing (4) consists of side walls firmly fixed to the frame, an opening front door and a removable top cover. To control the water heating temperature in the heat exchanger, a thermometer (10) is installed on the front panel.

The bed (5) is formed by two support brackets. A heat exchanger and a casing are fixed on the frame. The bed has holes for passing through the handrails (22 mm in diameter) for moving and transporting the apparatus.

An integral part of the frame is a reflector made of steel sheet (21), which significantly reduces the thermal effect of the heat exchanger on the floor.
