The boiler is designed for heating water and can be used in heating equipment. The boiler contains a combustion chamber, a vertical flue, water tanks of a heating and hot water supply system having adjacent heating surfaces, a pressure reduction unit whose inlet is connected to the main water pipe and an expansion tank that is an integral part of the pressure reduction unit. Between the main water pipe and the hot water tank there is a second pressure reduction unit. A vertical row of pipes is installed in the water tank of the heating system, inside which the combustion products of the fuel (for example, gas) pass, and the boiler contains a staggered horizontal row of pipes, flushed with combustion products, the internal area of which communicates with the tank of the heating system. The design of the boiler provides increased safety, reliability and efficiency by intensifying the heat exchange process.
DESCRIPTION OF THE INVENTION
The invention relates to heat engineering and can be used in heating boilers and domestic water heaters.
The closest analogue of the claimed invention is the technical solution for patent RU 2110017, F 24 D 3/08, 27.04.1998, which contains a combustion chamber, a vertical flue, water tanks of a heating and hot water supply system having adjacent heating surfaces, a pressure reduction unit, an inlet Which is connected to the main water pipe and expansion tank.
The disadvantage of this technical solution is the low efficiency of heat exchange.
The objective of the claimed invention is to increase safety, reliability and efficiency by intensifying the heat exchange process.
The task in view is achieved by the fact that the boiler comprises a combustion chamber, a vertical flue, water tanks of a heating and hot water supply system having adjacent heating surfaces, a pressure reduction unit whose input is connected to a main water pipe and an expansion tank that is an integral part of the pressure reduction unit between the main A second pressure reduction unit is located in the water tank of the heating system, a vertical row of pipes is installed in the water tank of the heating system, inside of which there are combustion products of fuel (for example gas), the boiler comprising a staggered horizontal row of pipes flushed with combustion products, internal The area of which is communicated with the tank of the heating system.
In this case, the second pressure reduction unit is made in the form of a storage tank of a hot water supply system with a valve connected to the main water pipe, a hinged link to it, on which a plug and a float interacting with the valve are fixed, and the heating circuit may comprise a pump , Installed on the boiler nozzle, for the selection of the hot water of the heating system.
The drawing shows the design of a universal boiler.

The universal heating boiler includes a burner 1, a combustion chamber 2, horizontal pipes 3, vertical pipes 4, a hot water tank 5, a heating system tank 6, a pump 7, an expansion tank 8, a first and second pressure reduction assemblies 10, a storage tank 11, A valve for supplying cold water 12, a float 13, a lever 14, a rubber plug 15 and a vertical flue 16. |
BOILER WORKS AS FOLLOWING
In the tank of the heating system 6, vertical pipes 4 are installed. Through them combustion products (for example, gas) pass. On the outside of the pipe, the water of the heating system is washed. Inside the boiler in the hot water tank 5 there is water from 60 to 250 liters, depending on the type of boiler at a temperature of 80-90 o C. When the pressure in the main water pipe drops to zero, the boiler continues to work, consuming redundant water. Resumption of water supply does not lead to emergency situations, the heating of water automatically resumes. When the set temperature is reached, the boiler burner 1 is automatically deactivated, switching to standby mode.
The water in the tank 6 of the heating system has a higher temperature; Heat is obtained directly from the combustion products of the fuel (for example, gas) through the walls of the combustion chamber 2, horizontal 3 and vertical 4 pipes. The water in the hot water tank 5 is heated through the heating surfaces adjacent to the tank 6.
Expansion tank 8 with the first pressure reduction unit 9 is used for automatic charging of the heating system.
To do this, a valve 12 is installed on the side surface of the body of the expansion tank 8. The valve communicates with the main water pipe of cold water. Through this valve there is a constant replenishment of the heating system and hot water supply.
When water evaporates from the system, the water level in the expansion tank 8 decreases. The float 13 is lowered and, by means of a lever 14 pivotally connected to the tank body, removes the rubber plug 15 from the opening of the valve 12. Water enters the expansion tank 8. Once the water level in the tank reaches a predetermined level, the float will rise and with the lever 14 and rubber stopper 15 tightly closes the opening of the valve 12. Thus, a constant water level is maintained in the heating system.
Similarly, the second pressure reduction assembly 10 operates.
The second pressure reduction assembly 10 is aligned with the storage tank 11. A valve 12 and a lever 14 are mounted on the side wall of the storage tank housing. The valve is a pipe with a conical truncated tip communicating with the main water pipe. The hole in the tip is determined by the flow of hot water and the volume of the storage tank. If the tank is large, then with the same hot water flow, the hole in the valve is selected with a smaller diameter and vice versa. At the same time, the storage tank 11 functions as an expansion tank. In case of thermal expansion of water when heated in a hot water tank, excess water rises and can be discharged into the atmosphere. For this purpose, there is a branch pipe installed slightly above the level of accumulation of water, which is determined by the position of the float 13.
A rubber plug 15 and a float 13 are rigidly mounted on the lever 14.
With the first pressure reduction unit 9, the heating circuit contour is continuously replenished.
At the same time, there is no need to increase the dimensions of the expansion tank 9, since the water level in the heating system circuit is maintained with the help of the float 13, the lever 14 and the plug 15 being constant.
In the circuit of the boiler heating system, the tank of the heating system 6 is directly connected to the expansion tank 8. In this case, if necessary, to connect the pump 7 for lifting water in multi-storey buildings, it should be installed on the hot water supply at the boiler outlet. This leads to the fact that the pressure in the boiler does not rise, but remains constant. It is determined only by the water pressure in the cold water makeup circuit, i.e. Height of expansion tank installation 8.
Thus, the expansion 8 and accumulation 11 tanks are set at a level above the point where the hot water tap is installed. They can be installed under the attic and the inputs of the lowering units 9,10 are connected to one valve from the main system of cold water of the city water supply. At the same time, discharging into the atmosphere and can be carried out through a single water supply.
When the water in the tank accumulates, the float rises and with the help of the lever 14 the rubber plug 15 closes the opening of the valve 12.
The level of water in the storage tank 11 is kept constant until the hot water tap is opened. With the flow of hot water, the hot water tank of the 5 boiler is replenished with cold water from the storage tank 11. Until the water supply in the hot water boiler 5 of the boiler and the storage tank 11 is used, the water head will be large and constant. Thus, there is a constant replenishment of the water supply in the storage tank from the main water pipe, the time of filling the tank depends on the diameter of the opening of the valve 12.
