Below the shuttle door 6 (Fig. 1), a secondary air gate 7 (Figs. 1, 2) is located, made in the form of a blower flap containing two plates in which vertical slots are made. When the plates move horizontally, the cross section of the slit changes and the amount of air entering under the grates 8 (FIG. 1) is regulated and thereby the intensity of combustion is regulated. Inside the lower part of the housing 1 (Figs. 1-3) there are grates 8 (Fig. 1) and an ash pan 9 (Fig. 1), which serves to collect ash. Grids 8 (FIG. 1) are a distribution grid that serves to pass air and separate the blower chamber 10 (FIGS. 1, 2) and the combustion chamber 11 (FIGS. 1, 2). The combustion chamber 11 (Fig. 1, 2) is laterally and laterally limited by water-cooled sections of the heat exchanger 4 (Fig. 1), and is closed in front by the front sheet of a gas burner device (GGU), on which the collector of the main burners 12 is fixed (Figs. 1-3) with nozzles and mounted bracket ignition burner 13 (Fig.1, 2). On the left of the front sheet there is a viewing window (not shown in the drawing) for monitoring the operation of the pilot burner 13 (Figs. 1, 2), as well as for igniting the gas-air mixture. The main burner 12 (Fig.1-3) is made of heat-resistant stainless steel and placed evenly under the heat exchangers 4 (Fig.1), creating a uniform thermal field in the combustion chamber of the combustion chamber 11 (Fig.1, 2), which eliminates the formation of local zones overheating of the heat exchanger 4 (figure 1) and its destruction. Above the grates 8 (FIG. 1), a shield 14 (FIG. 1) is installed, which serves to prevent spontaneous loss of combustion products from the boiler. The boiler is equipped with a water heater (boiler) 15 (Fig. 1) located in the upper part of the internal volume of the boiler, in which the heating element is made in the form of a coil from a thin-walled corrugated pipe. A water heater (boiler) 15 (Fig. 1) serves to provide clean hot water that goes to household needs. On top of the heat exchanger 4 (FIG. 1), a smoke collector 16 (FIGS. 1, 2) is installed, with a draft adjustment gate 17 (FIG. 1) located inside the smoke collector 16 (FIGS. 1, 2).

In the lower part of the housing 1 (Fig. 1, 2) a pipe 18 is welded (Fig. 1, 2) for connection to the return pipe of the heating system, which serves for supplying chilled water to the boiler, and the upper part of the housing 1 (Fig. 1, 2 ) a pipe 19 is welded (Fig. 1, 2) for connection to the supply pipe 20 (Fig. 1) of the discharge line of the heating system, which serves to divert hot water from the boiler to the heating system. Behind the outlet pipe 19 (Fig. 1, 2) of the supply pipe 20 (Fig. 1) of the discharge line of the heating system, a temperature gauge 21 (Fig. 1) is made in the form of a bracelet thermometer. At the drain end of the supply pipe 20 (FIG. 1), a safety valve 22 (FIG. 1) is installed, which is configured to operate at a pressure in the heating system of 1.5 + -0.1 kgf / cm 2. The boiler is equipped with a chipper 23 (FIG. 2), providing an increase in the path of passage of flue gases. The hot water heating boiler with selection of hot water is equipped with a safety automatics with a gas burner containing a draft sensor 24 (Fig. 1) installed on the loading door 5 (Fig. 3) and configured to turn off the boiler in the absence of draft in a chimney containing a flame sensor 25 (FIG. 3) mounted on the panel of the gas burner device 26 (FIG. 3), a temperature sensor for the heat transfer medium 27 (FIG. 3) located in the cavity of the water jacket 3 (FIGS. 1, 3), a control and safety unit 28 (FIG. .2, 3) screwed tightly second end of manifold 12 main burners (1-3) Gas burner device. The control and safety unit 28 (FIGS. 2, 3) comprises a safety valve, a control valve, a pressure stabilizer and a water temperature regulator.

The heating boiler with the selection of hot water can increase efficiency due to the large volume of the convection surface of the water jacket 3 (1, 3).

The operation of the heating boiler with the selection of hot water.

For a solid fuel boiler:

- it is necessary to melt the boiler with dry wood, loading the combustion chamber 11 to half its height and watching it so that hot coals cover all the grates 8, gradually load coal after igniting the upper layer;

- loading fuel to produce in small portions, quickly, without leaving the loading door 5 open for a long time, in order to prevent a large amount of cold air from breaking into the combustion chamber 11;

- load fuel so that the combustion level is not higher than the lower edge of the boot door 5;

- download the entire volume of the combustion chamber 11 to complete in about an hour;

- after the coal has flared up well, set the draft gate valve 17 to a position that provides optimal fuel combustion, check the draft in the opening of the loading door 5.

By means of the secondary air gate 7, the amount of air entering under the grid-irons 8 is regulated and thereby the combustion intensity is regulated. Through the ashpit 9 is the collection of ash.

For boilers using natural gas, it is necessary:

- ventilate the room in which the boiler is installed for 10-15 minutes;

- check for draft in the chimney;

- open the gas valve (not shown) of the gas supply to the safety automatics with a gas burner device;

- to ignite the ignition burner 13 and the main burners 12 of the gas burner device (GGU).

Turn the control knob (not shown) of the water temperature regulator of the control and safety unit 28 to any desired temperature for heating the water in the boiler and check the gas flow on the main burners 12 visually through the inspection window. After the combustion chamber 11 has melted, the heat heats the water jacket 3, which has a developed convection surface. Heated water enters the pipe 20 forcing heating lines. Heated water enters through the pipe 19 to the discharge pipe 20 of the heating line, heats the batteries and heating pipes and then, after heat is transferred through the batteries and the heating pipes to the rooms, returns through the pipe 18 to connect to the return pipe of the heating system, which serves to supply chilled water to the boiler. Thus, a closed cycle of the water circuit in the pipelines 20 injects the heating line to the pipelines of the return line of the heating system. Pure water through a pipeline and through separate nozzles enters a water heater (boiler) 15, located in the upper part of the internal volume of the boiler, which is heated from a water jacket 3, heated to a temperature of less than 93 degrees C and supplied to household needs. When the set water temperature of the boiler is reached, the automatics shuts off the gas supply to the gas burner device to the main burners 12 and turns it on again when the temperature drops to a value determined by taking into account the hysteresis zone established by the automation, which should not exceed 10 C. Gas supply to the main burners 12 of the boiler its work process automatically stops in the following cases:

- lowering the gas pressure in the pipeline below 600 Pa,

- insufficient traction in the boiler furnace,

- extinction of the flame of the ignition burner 13,

- heating the water in the boiler above 93 degrees C, when the sensor controls the temperature of the coolant 27.

Re-ignition of the boiler can only be carried out after troubleshooting. Automation of regulation and safety provides temperature control of water at the outlet of the boiler, gas cut-off when the flame of the ignition burner 13 is extinguished in the absence of draft and when the network pressure drops below the minimum.

The technical result of ensuring safe operation of the boiler when operating on natural gas is provided by a safety valve 22, which is configured to operate at a pressure in the heating system of 1.5 + -0.1 kgf / cm 2.
