Description

The claimed utility model relates to devices for heating water and can be used in heating equipment and for hot water supply.

Known, selected as the closest analogue, a device for heating a liquid containing a gas supply pipe with an automatic gas supply control unit mounted thereon and connected to a gas burner equipped with an igniter and installed in the upper part of the combustion chamber formed by a cylindrical casing located in the housing and communicated with him, while the housing is equipped with a pipe exhaust of combustion products, in addition, in the gap between the generatrix of the casing and the inner surface of the housing around the casing a, there is a pipeline made in the form of a spiral with which a thermostat is connected, which, in turn, is connected to a gas supply control unit (French Patent for Invention No. 2404811, class IPC F23C 3/00, publ. 04/27/1979 )

The location of the gas burner in the upper part of the combustion chamber allows you to use the specified apparatus with a high gas supply pressure, accompanied by intense combustion, otherwise only the upper part of the combustion chamber will be heated.

The heat released during gas combustion is expended on heating the cylindrical casing, then there is a heat exchange process between the combustion chamber and air between the combustion chamber and the inner surface of the housing, and after this there is heat exchange between the heated air and the pipeline, made in the form of a spiral, as well as with the liquid located in the pipeline. However, part of the heat is lost due to the fact that the housing is equipped with a pipe for the release of combustion products.

The location of the thermostat on the pipeline, made in the form of a spiral, allows you to adjust the temperature of the liquid only within the specified apparatus, while not taking into account the temperature of the liquid entering the hot water supply and heating system.

The disadvantage of this apparatus is that the heat generated during gas combustion is not used rationally, in addition, temperature control is carried out in it by completely stopping gas combustion and re-igniting the gas in the burner, which leads to rapid wear of the igniter device, in addition, cutting off the gas supply to a gas burner occurs only if the water temperature exceeds the maximum permissible value.

The technical result that can be obtained in the declared useful

model, is the creation of a hot water boiler with the most efficient use of the heat released during combustion of gas, with the most safe operation.

The claimed hot water boiler consists of a housing 5 in the lower part of which a combustion chamber 9 is placed, and in its lower part a gas burner 6 is provided, equipped with an ignition device 8. The upper part of the combustion chamber 9 is connected to at least one through-pipe 14. the number of through pipes 14, the heat transfer surface will increase. Inside each passage pipe 14, at least one swirler 15 is installed, made, for example, in the form of a half-open damper or nozzle. The internal cavity of the casing 5 and the passage pipes 14 are in communication with a chimney 11 located in the upper part of the casing 5, which is equipped with a cover 12. The chimney 11 is in communication with the exhaust pipe 10, which is equipped with an opening door 21. The housing 5 is equipped with two pipes connected to the heating system, one of which is the inlet pipe 16, and the second is the exhaust pipe 17. The inlet pipe 16 is designed to inlet cold water into the housing 5 from the heating system, and the exhaust pipe 17 is designed to discharge hot water into the heating system. The housing 5 is equipped with a thermometer 7, in communication with the internal cavity of the housing 5.

A gas burner 6 is connected to a gas supply pipe 1, on which an automatic gas supply control unit 2 is mounted. In the cover 12 is installed a thrust sensor 13 connected to an automatic gas supply control unit 2. The automatic gas supply control unit 2 is connected to a thermogenerator 18 and a thermocouple 19 located in the ignition device 8. A limit thermostat 20 is placed on the cover 12. On the housing 5 there is a thermostat 3 connected to the thermostat 20

limit heating. Inside the housing 5 there is a sensor 4 of the thermostat 3. An automatic gas control unit 2 connected to the thermostat 3.

The igniter device 8, shown in Fig. 4, consists of an ignitor 23 on which a thermocouple 19 is mounted, pizzero candles 22, the electrodes of which are directed to the output part of the ignitor 23, and a heat generator 18 installed in the immediate vicinity of the ignitor 23.

The boiler is as follows.

Before starting the operation of the boiler in the housing 5 through the inlet pipe 16, water is poured from the heating system.

When the boiler is turned on, the automatic gas supply control unit 2 blocks the gas supply from the gas supply pipe 1 to the gas burner 6 and supplies gas to the igniter 23. At the same time, the automatic gas supply control unit 2 includes a puffer candle 22. After the gas in the igniter 23 flares up, the automatic gas supply control unit 2 will receive a signal from the thermocouple 19 about this and turn off the candle 22. In this case, the thermogenerator 18 begins to heat up, generating electrical voltage. The heat generator 18 is an independent source of electrical energy for powering the automatic gas supply control unit 2. After the voltage in the heat generator 18 is enough to open the valve of the gas burner 6, the automatic gas control unit 2 will open the specified valve and gas will begin to be supplied to the gas burner 6, igniting from the flame on the igniter 23.

The burning gas from the gas burner 6 enters the combustion chamber 9 and burns in it, turning into combustion products. Then, the combustion products enter the passage pipes 14, where heat exchange occurs between the combustion products and the internal surfaces of the passage pipes 14. To increase the intensity of the heat exchange process, swirlers 15 are provided in the pipes 14, which increase the turbulence of the combustion products. After exiting the passage pipes 14, the combustion products pass through the chimney 11 and then into the pipe 10 of the release of combustion products. From the pipe 10, the combustion products go into the atmosphere. To regulate the draft on the pipe 10, a door 21 is provided, opening or closing which you can increase or decrease the draft manually.

Heated in the process of heat exchange with the combustion products, the through pipes 14 give off heat, filling the internal cavity of the housing 5 with water. Water is heated and enters through the outlet pipe 17 into the heating system, and the cooled water of the heating system through the inlet pipe 16 again fills the internal cavity of the housing 5 and the process of transferring heated water to the heating system, and chilled water into the housing 5 is repeated.

Upon reaching the water temperature in the inside of the boiler body 5 90 ° C, thermostat 3

gives a signal that the water temperature inside the housing 5 has exceeded the maximum permissible value to the automatic gas supply control unit 2, which shuts off the gas supply from the gas supply pipe 1 to the gas burner 6.

In the event of a failure of thermostat 3 or an incorrect setting of thermostat 3 to a temperature above 90 ° C, the limit heating thermostat 20 provides an automatic safety shutdown of the gas supply to the gas burner 6. When the water temperature in the boiler body 5 reaches 93 ° C - 100 ° C, the limit heating thermostat 20 connected to the sensor 4 of the thermostat 3 sends a signal about reaching a critical temperature to the automatic gas supply control unit 2, which turns off the gas supply from the gas supply pipe 1 to the gas burner 6. When lowered and the temperature of the water in the housing 5 by 25-30 ° C, the gas supply control unit 2 automatically resumes the gas supply to the gas burner 6 and it ignites from the igniter flame 23.

If there is no draft in the chimney 11, the draft sensor 13 sends a signal about the absence of draft in the chimney 11 to the automatic gas supply control unit 2, which cuts off the gas supply from the gas supply pipe 1 to the gas burner 6. The draft sensor 13 is made in the form of a bimetallic plate with a microswitch. In the absence of draft, the electric capacity of the plate changes and the microswitch signals that there is no draft in the chimney 11 to the automatic gas supply control unit 2, while the automatic gas supply control unit 2 receives a signal on the absence of draft in the chimney 11 and turns off the gas supply from the supply pipe 1 gas to a gas burner 6.

If, during operation of the boiler, the flame extinguishes on the gas burner 6 and the igniter 23, then the thermocouple 19 installed in the ignition device 8 is cooled in the absence of the combustion process, while the automatic gas supply control unit 2 receives a signal about the cooling of the thermocouple 19 and turns off the gas supply from the pipe 1 for supplying gas to the gas burner 6.

The user himself can manually stop the operation of the heating boiler, using a thermometer 7 communicated with the internal cavity of the housing 5, and determining that the water temperature in the housing 7 is sufficient for the normal functioning of a person.

Thus, due to the introduction of at least one through-pipe, a thermocouple, a limit heating thermostat, and a draft sensor into the boiler, the heat generated during gas combustion will be used as efficiently as possible, while operating the boiler as hot as possible.
