INVENTION
Russian Federation Patent RU2075011
HOT WATER UNIT
Name of the inventor: Shmagin Yury; Vladimir Fedorov Fedoseevich
The name of the patentee: Shmagin Yury; Vladimir Fedorov Fedoseevich
Address for correspondence:
Starting date of the patent: 1994.04.13
Use: in the energy sector at the local heating and hot water supply of residential houses and public buildings.
The inventive improvement of consumer qualities ensured by the fact that the device comprises a water-heating furnace 1 for solid fuel grate and above the furnace coil 1, which are enclosed in an airtight casing 8 having a boot and shurovochnuyu door. When this apparatus is provided with the gas combustion chamber 5 with the stationary gas burner units and disposed above the coil mounted in the same casing 8, and both the furnace 1 and 5 in the upper part are interconnected by pipe 9 and in each of them under said pipe 9 is formed beginning chimney located in the space between the furnaces 1 and 5 and the housing 8. The device is provided with a cam 12 and mounted above the furnaces 1 and 5, connected to the output ends of the chimneys and having at the front end of the cleanout door, the switching device for operating the furnace flue and fume collection tube 15 with an umbrella, tyagostabiliziruyuschimi holes and overlying ring using solid fuel. In operation, the apparatus involved in the heat exchange surface of the heat exchangers of both inserts, which improves efficiency.
DESCRIPTION OF THE INVENTION
The invention relates to power engineering and can be used for local heating and hot water supply of residential houses and public buildings.
Known "Device for heating water, in particular hot water boiler" (German Patent DE 3615805 A1, published. 12/11/87), consisting of a furnace, gas-burning devices, fuel supply system, a heat exchanger with a capacity around the furnace, fume collection device with an exhaust fan, condensate . The combustion of fuel in the furnace, the heat generated is transferred to the heat exchanger located in the water and it is heated. combustion products emitted into the chimney due to the fan, the resulting condensate is collected in a container at the bottom of the unit.
The disadvantages of the device are:
- installation and operation of the complexity of the device in connection with the need to supply device for an exhaust fan;
- insert the device does not provide for the use of solid fuel.
Known and "Zhidkotoplivnyy and gas water heater" (US Patent No. 4,664,096, to publish. 12/5/87), consisting of a furnace with a device for combustion of liquid and gaseous fuels, heat exchanger, system conversion and switching fuels, heat exchanger, system conversion and switching fuels. When burning liquid or gaseous fuel in the furnace, water contained in the cavities of the capacitive exchanger is heated through its wall hot products of combustion.
The disadvantages of this water heater are:
- vodognagrevatelya furnace does not provide for the use of solid fuels;
- lack of hot water circuit, which makes it impossible to use hot water for domestic use.
The closest in technical essence to the claimed technical solution is the "hot water boiler heating the steel to domestic hot water" (boiler TGVm COP-16 Operating Instructions, Rostov-on-Don, 1989) containing a furnace for solid fuel grate and located above the furnace coil is enclosed in a sealed housing having a boot and shurovochnuyu door. When transferring the boiler to gas furnace is equipped with gas-burning devices that are installed with shurovochnoy door and grate. The combustion of the fuel through the furnace wall heat transferred to the water located in the space between the furnace and the enclosure. Hot water coil heats the domestic hot water, as well and served in a hot water heating system.
Boiler disadvantages are:
- there are operational difficulties in retrofitting the boiler with solid fuel to gas and vice versa, because It must be brought to these works specialist Gazovik and connected (or disconnected) Communications gas boiler to gas line network;
- underdeveloped teplovosprinimayuschuyu boiler has a surface, and hence lower thermal efficiency.
The technical problem posed in the application for the invention is to eliminate these drawbacks, ie, in improving the consumer qualities water heating apparatus, and is achieved by the fact that it is provided with a gas furnace with a stationary gas burner units and disposed above the coil mounted in the same housing, wherein both the furnace in the upper portion interconnected pipe and each of them under the said nozzle formed the beginning of the chimney, which is located in the space between the furnace and the body, and the device is further equipped with a camera mounted above the furnace connected to the output ends of the chimneys and having at the front end of the cleanout door, switching device chimneys on a working furnace and fume collection tube with an umbrella, tyagostabiliziruyuschimi holes and overlying ring using solid fuel.

The proposed water heating apparatus comprises a furnace for solid fuel with grate 1 2 3 loading and shurovochnuyu 4 doors, gas furnace with 5 gas burner units 6 located above the furnaces coil 7 surrounding the firebox and the coil housing 8. furnace at the top of the pipe 9 connected, below which begin in each furnace flues 10 and 11 extending into the space between the furnaces and the housing. Chimneys from furnaces come in above the furnaces chamber 12 having the personal end of the cleanout door 13, the cover slab of the chimney 14 and fume collection tube 15 with an umbrella and tyagostabiliziruyuschimi holes. Socket is currently in the ring 16 with reverse holes. At the bottom of the furnace 1 is set Zolnikova box 17.
UNIT HOT WATER WORKS AS FOLLOWS
In the initial state before using the water heating unit is preparing to use a particular type of fuel. If you are using solid fuel, the gas valve ahead of the machine must be closed. Through the cleanout door 13 overlaps lid 14 and a chimney 11 is regulated by the ring 16 so that the holes do not coincide with the nozzle apertures 15 tyagostabiliziruyuschimi.
After setting the unit to the selected type of fuel, for example, on solid, the device is ready for use.
Closes the gas valve to the unit, the furnace 1 is loaded with solid fuel through a loading door 3 and door 4 through shurovochnuyu fuel ignited. Hot products of combustion from the furnace 1 through the pipe 9 penetrate the gas furnace 5 are omitted and consistently pass the chimney 10 and the camera 12, and leave the machine, leaving the fume collection pipe 15. Through the wall of the furnace 1, part of the furnace 5, the nozzle 9, the chimney 10, chamber 12, the nozzle 15 partially fume collection combustion give up its heat return water coming from the water heating system in a container formed furnaces and 1.5 housing 8. water heated is fed back into the heating system. Located in the hot water coil 7 medium, and hot and running water in the coil is supplied to the hot water for domestic use. Mechanical balances solid fuel through the gaps of the grate 2 Zolnikova enter the box 17 and removed.
When using gas as fuel opens the gas valve re kindled apparatus and gas-burning device 6. Hot gas combustion give off their heat to the water, on the fume collection path: the gas burner 5, 9 tube, the furnace 1, the flue 11, a camera 12, a branch pipe 15. At the end of use water heating apparatus using gas fuel gas valve is closed before the apparatus.
Due adopted dymooborotov system in the process of heat transfer involves heat transfer surfaces both furnaces, which ensures high efficiency, minimum size and weight of the device.
CLAIM
Water heating apparatus comprising a furnace for solid fuel to the grate and above the furnace coil is enclosed in a sealed housing having a boot and shurovochnuyu door, characterized in that it is provided with a gas furnace with a stationary gas burner units and disposed above the coil mounted in the same housing, wherein both the furnace in the upper portion interconnected pipe and each of them under the said nozzle is formed beginning chimney located in the space between the furnaces and the housing, wherein the apparatus is further provided with a camera mounted above the combustion chamber connected to the outlet ends of the chimneys and having at the front end of the cleanout door, switching device chimney on a working furnace and fume collection tube with an umbrella, tyagostabiliziruyuschimi holes and overlying ring using solid fuel.
