The essence of the utility model.

The steel heating boiler, contains a housing 1 (Fig.1-3), which is a welded box-shaped structure, closed from the outside by facing panels 2 (Fig.1,2). At the bottom of the boiler body 1 (Figs. 1-3), the base 3 (Figs. 1-3) is made, and on top of the boiler body 1 (Figs. 1-3), a cover 4 (Figs. 1-3) is mounted. On the front side of the housing 1 (Figs. 1-3) of the boiler, there is a loading door 5 (Figs. 1-3), which serves to load solid fuel, and a shurovoi door 6 (Figs. 1-3), intended for kindling, as well as for extract focal residues. A steel heat exchanger 7 (Fig. 1) is installed in the internal volume of the boiler body 1 (Figs. 1-3), forming a closed loop of the heat-transfer medium with the cavity of the water jacket 8 (Fig. 1). On the pilot door 6 (Figs. 1-3), a shutter 9 (Fig. 2) is located, which controls the amount of air supplied under the grates 10 (Fig. 1). In the lower part of the housing 1 (Fig. 3) there is a bracket 11 (Fig. 3) of the shutter 9 (Fig. 2) configured to control the amount of air supplied under the grates 10 (Fig. 1) with a change in the burning rate of solid fuel and the coolant temperature . The boiler contains a flap 12 (figure 1), made with the possibility of eliminating spontaneous loss of combustion products from the boiler and to regulate the supply of secondary air, in order to ensure economical combustion of fuel. Inside the boiler body there are grates 10 (FIG. 1), an ash pan 13 (FIG. 1), used to collect ash, and a combustion chamber 14 (FIG. 1), having increased dimensions of the combustion space, which is laterally and laterally limited by water-cooled sections of the heat exchanger 7 (FIG. 1). The loading door 5 (Figs. 1-3) of the boiler, also having enlarged dimensions, is provided with a shutter 15 (Fig. 1), which forms additional thermal insulation in the form of a thermal bridge during the combustion of solid fuel, to ensure continuous operation on wood, which serves to the heat from the combustion chamber 14 (FIG. 1) during combustion of the fuel heated the loading door 5 less (FIGS. 1-3). The boiler includes a convector 16 (Fig. 1) installed in the upper part of the furnace space and made of horizontally arranged square steel pipes, which, when solid fuel is burned, is heated from flue gases and gives off heat to the heat carrier. On top of the rear wall of the boiler there is a chimney 17 (Figs. 1, 3), which serves to collect and exhaust flue gases, in which a chimney gate 18 (Figs. 1, 3) is installed, which serves to regulate the draft. The chimney 17 (Fig.1, 3) is fixed to the smoke collection pipe 19 (Fig.1, 3) of the boiler, of rectangular cross-section, located on the rear wall of the boiler. The lower part of the chimney body 17 (Figs. 1, 3) is made opening for easy cleaning of the convector 16 (Fig. 1) of the boiler during maintenance by the consumer. On the body 1 (Figs. 1-3) of the boiler there is a pipe 20 (Figs. 1, 3) for connecting to the return pipe of the heating system, which serves for supplying chilled water to the boiler, and a pipe 21 (Fig. 3) of the heating discharge line for connecting to supply pipe, used to divert hot water from the boiler to the heating system. On the lid 4 (Fig.1-3) is a water temperature indicator 22 (Fig.1, 3), which informs about the temperature of the coolant. The boiler is equipped with a water heater 23 (Figs. 1-3), placed inside the casing 1 (Figs. 1-3) of the boiler in the hot water environment of the heating system, intended for the preparation of hot water for domestic needs. The water heater 23 (Fig.1-3) has nozzles 24 (Fig.1, 3), through which clean water enters it. In the upper part of the housing 1 (Figs. 1-3), on the right wall of the boiler, an axle box 25 (Fig. 3) is mounted to accommodate a temperature regulator with a chain link 26 (Fig. 2) of the shield 12 (Fig. 1) of the air supply made with the ability to maintain a given temperature of the coolant by regulating the supply of secondary air. On the housing 1 (figure 3) there are additional fittings 27 (figure 3). The steel heating boiler has a developed convection pipe part, which ensures an increase in boiler efficiency.

The operation of the boiler is as follows.

Before putting the boiler into operation, it is necessary to fill the system with water until it appears from the overflow pipe of the expansion tank, then open the chimney gate 18, open the tap on the return line of the heating system (not shown in the drawing) and check for draft. When the boiler is operating on solid fuel through the loading door 5, solid fuel is loaded. The boiler is fired up through the shurovochny door 6, as well as the extraction of the focal residue. The adjustment of the draft of smoke and gases is carried out by the gate of the chimney 18. On the shurovochny door 6 there is a shutter 9, which controls the amount of air supplied under the grates 10, thereby controlling the intensity and temperature of combustion. The boiler contains a shield 12, which eliminates spontaneous loss of combustion products from the boiler and serves to adjust the supply of secondary air.

The operation of the boiler:

- it is necessary to melt the boiler with dry wood, loading the furnace to half its height and watching it so that the hot coals cover the entire grate plate 10, then gradually load the coal;

- 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 14;

- load fuel in such a way that the combustion level is not higher than the edge of the boot door 5;

- Download the entire volume to complete in about an hour;

- after the coal has flared up well, set the shutter 7 in a position that ensures optimal combustion of fuel;

- not to allow a large accumulation of ash in the combustion chamber 14, to clean twice a day. Cleaning from ash and soot deposits of all surfaces of the combustion chamber to produce as necessary;

- when slag accumulates in the furnace chamber 14, it is necessary to quickly select it, leave all unburned coal (heat) in the furnace chamber 14, and then make another loading of fuel.

During the operation of the boiler, the heated gases resulting from the combustion of solid fuel rise to the top and pass through the convector 16 and enter the chimney 18. This leads to the process of heat transfer from the water jacket 8. The heat exchanger 7 located in the water jacket 8 is heated and transfers part heat to the water circulating in the hot water supply system, which is connected to the hot water supply system. When burning fuel, the water heated in the water jacket 8 enters the pipe 21 of the heating pressure line for connection to the supply pipe and which serves to divert hot water from the boiler to the heating system. Hot water heats the batteries and heating pipes and then, after heat is transferred through the batteries and heating pipes to the rooms, returns through pipe 20 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 injects the heating line to the pipelines of the return line of the heating system. The door of the loading boiler 5 is equipped with a shutter 15, forming a thermal bridge, made in the form of thermal insulation, which serves to ensure that the heat from the combustion chamber 14 when the fuel burns less warms the loading door 5. The water temperature in the boiler is fixed by the water temperature indicator 22.

Features of the water heater 23 are as follows:

- It is recommended to start using the water heater 23 after the boiler enters the operating mode - when the temperature of the coolant reaches 85-90 ° C;

- the required temperature of water heating by the water heater 23 is controlled by changing the amount of water entering it from the water supply network, through a valve (not shown) in the outlet.

During operation, keep the temperature of the hot water in the boiler no higher than 90 ° C. Pure water through a pipeline and through separate nozzles 24 enters a water heater 23, located in the upper part of the internal volume of the boiler, is heated from a water jacket 7, heated to a temperature of less than 93 degrees C and supplied to household needs. The water heater 23 is allowed to be connected to the water supply networks (lines) with a water pressure in the network of not more than 0.6 MPa (6 kgf / cm ² ) in order to avoid the failure of the water heater 23.
