[0002] The present disclosure relates to a burner, a water heating device including such a burner, and a method for controlling the burner.

State of the art

[0003] A water heating device is a device that heats a fluid. The fluid may be water. The water heating device can heat the desired area by releasing heated water to a consumption source or by delivering heated water to a heating duct. The water heating device for heating can be a boiler.

[0004] Accordingly, for heating water in a water heating device, the water heating device generally has a structure that, with the help of a burner, can cause a combustion reaction to produce a flame and combustion gases, and can also heat water using the heat transferred from the flame and the heat transmitted from combustion gases.

[0005] The burner generates an electrical spark in the air and fuel to cause a combustion reaction. Accordingly, air and fuel must be supplied to the burner, and the water heating device must release combustion gases resulting from the combustion reaction through the gas pipeline.

[0006] When the gas line connected to the water heating device is made long in the up/down direction, and negative pressure is generated in the gas line, the speed at which combustion gases escape may increase, and a blow-off phenomenon may occur in which the flame is usually in the burner not formed. Since in the case of a burner used for a high-power boiler, it is possible to control only the supply or non-supply of fuel, while the air is simply supplied or not supplied, it is difficult to cope with the separation phenomenon when it occurs.

[0007] In addition, when the gas pipeline is long, explosive ignition may occur because resistance corresponding to the length of the gas pipeline is generated, and the gas pipeline may be torn due to explosive ignition or may deviate from its proper location.

[0024] In FIG. 1 is a perspective view illustrating a burner 10 of a water heating device 1, and a portion adjacent to the burner 10, according to one embodiment of the present invention. In fig. 2 is a perspective view of a burner 10 of a water heating device 1 according to one embodiment of the present invention.

[0025] As shown in the drawings, the water heating device 1 according to one embodiment of the present invention includes a combustion chamber 20 and a burner 10. In the description and drawings of the present invention, the left/right direction and the forward/backward direction are directions perpendicular to the direction up/down and are relative directions used for convenience in presenting the invention, and may differ depending on the position of the water heating device 1.

[0026] The water heating device 1 may include a combustion chamber 20, a burner 10, and a heat exchanger (not shown). The burner 10 may be coupled to one side surface of the combustion chamber 20, and a portion of the burner 10 may be inserted into the combustion chamber 20. The burner 10 may be connected to the combustion chamber 20 along a horizontal direction. As shown, the burner 10 can be attached to the combustion chamber 20 from the rear surface of the combustion chamber 20 to the front side, but the side surface and the direction to which and in which the burner 10 is attached is not limited to this.

[0027] Combustion gases are generated when a flame occurs at a portion of the burner 10 inserted into the combustion chamber 20 and a combustion reaction occurs, and the combustion gases flow from the combustion chamber 20 into the heat exchanger and exchange heat with the water flowing in the heat exchanger, heating it. The water heated in the heat exchanger can be used for heating or can be supplied as hot water.

[0028] The burner 10 may be a gun burner 10. The gun burner 10 is a burner in which an air supply configuration, a fuel supply configuration, and an ignition configuration are combined into a unit.

[0029] Burner 10 may include fuel supply portions 12, 15, 17, and 18, air supply portions 13 and 14, ignition portion 19, pressure data acquisition portion 16, and a processor.

[0030] Part 19 for ignition

[0031] The ignition portion 19 is configured to generate a spark to ignite the supplied fuel and air. The distal end of the ignition portion 19 inserted into the combustion chamber 20 can generate a spark, and the ignition portion 19 may be passed through the opening of the mixer 13, which will be described below, so that the ignition inner end, that is, the distal end of the ignition portion 19, is in the combustion chamber, that is, in the internal space of the combustion chamber 20. Although in this embodiment of the present invention it is disclosed that the ignition portion 19 is a spark plug, a device performing ignition in a manner other than a spark plug may be used as the ignition portion 19.

[0032] The ignition portion 19 may cause the fuel-air mixture to be ignited by an electric spark. Since an electric spark is generated in a situation where air and fuel supplied by the fuel supply portions 12, 15, 17 and 18 pass through the mixer 113 to form a mixture, a flame may be generated.

[0033] The inner ignition end of the ignition portion 19, which is its distal end in the reference direction, may be located adjacent to the fuel injector 12 of the fuel supply portions 12, 15, 17, and 18.

[0034] Housing 11

[0035] The burner 10 according to an embodiment of the present invention may include a housing 11. The housing 11 is a member that is the frame of the burner 10 and may include a blower pipe 112, a mixer 113, and a frame 111.

[0036] The frame 111 is a member connecting the blower fan pipe 112 and the air supply parts 13 and 14, and the components that will be disclosed below can be connected to each other by supporting the frame 111. The interior area of the frame 111 is empty and may cause the air supplied by the air supply portions 13 and 14 to be supplied to the blower pipe 112.

[0037] The blower pipe 112 is a member surrounding the fuel injector 12 inserted inside the combustion chamber 20 and a portion of the ignition portion 19, and is connected to the air supply portions 13 and 14. The blower pipe 112 may have an inner space in which air blown by the air supply portions 13 and 14 flows, and an outlet hole which is an opening opening into the combustion space in the reference direction. The air injected by the air supply portions 13 and 14 may be discharged into the combustion space through the outlet and may be mixed with the fuel to meet the spark and form a flame. The mixer 113 may be located in the outlet, and at least a portion of the outlet may be covered by the mixer 113.

[0038] The blower pipe 112 may have an outer cylindrical shape that opens in the support direction. The blower pipe 112 may be connected to the combustion chamber 20.

[0039] The mixer 113 is an element designed to produce an even flame. The mixer 113 can cause the fuel discharged by the fuel supply portions 12, 15, 17 and 18 to be mixed together with the air supplied by the air supply portions 13 and 14 to reach the combustion space.

[0040] The mixer 113 may have a plurality of mixing parts so that the fuel and air are well mixed. The mixing portions may be located at locations corresponding to the locations of the plurality of fuel injectors 12. The plurality of mixing portions may be positioned in a circumferential direction surrounding the central circle. The mixing parts may be provided with mixing channels that open in a forward/rearward direction. Accordingly, the fuel discharged by the fuel injector and the air can be mixed in the mixing channels and can be discharged into the combustion space. A plurality of mixing parts can be connected to each other to form a ring structure.

[0041] Part 13 and 14 for air supply

[0042] In FIG. 3 is a perspective view illustrating the rotating portion 132 of the blower 13 according to one embodiment of the present invention.

[0043] The air supply parts 13 and 14 are components for forcing air supplied from outside into the combustion chamber 20. Accordingly, the air supply portions 13 and 14 may include a blower fan 13 and an air supply line 14 for supplying air to the blower fan 13.

[0044] The blower 13 is a device that, in accordance with its rotation, forces air into the combustion chamber 20 for combustion reaction. The blower fan 13 may include a blade portion 131 that forces air into the blower fan tube 112 while rotating, and a rotary portion 132 that generates a rotational drive force to rotate the blade portion 131 and supplies a rotational drive force to the blade portion 131. The blade portion 131 may represent an impeller in a casing. The rotary portion 132 may be a brushless direct current (BLDC) motor. Accordingly, through control by the processor, the speed of the rotary portion 132 can be accurately controlled. The blade portion 131 can be rotatably mounted so that the left/right direction is the axial direction, and the rotary portion 132 as shown can be connected to the right side scapular part 131.

[0045] The air supply portions 13 and 14 can be controlled so that air is forced into the blower pipe 112 at a plurality of different flow rates. The processor may exercise control to drive the rotary portion 132 at different speeds by applying different amounts of current to the rotary portion 132. At a low level, the processor may provide a predetermined low level current to the rotary portion 132, and at a high level, the processor may provide a high level current. greater than the low level current for the rotation portion 132. The processor may control the air supply portions 13 and 14 so that the blower motor 223 operates at a low level at the time of ignition and operates at a high level after ignition.

[0046] Low level means a level at which the blower motor 13 rotates at a low level speed, so that air is supplied at a low level flow rate, which is a predetermined flow rate. The low level speed may be determined by the low level excess air ratio of the burner 10 or the amount of heat generated. A high level means a level at which the rotary portion 132 rotates at a high level speed greater than a low level speed so that air is supplied at a high level flow rate greater than a low level flow rate.

[0047] The air supply line 14 is a pipeline connected to the blower fan 13 so that air from outside is supplied to the blower fan 13. As shown, the air supply line 14 may be connected to the left side of the blade portion 131, opposite to the rotational portion 132 relative to the blade portion 131, and may supply air to the rotating portion 132. The air supply line 14 may include a connecting conduit 141 that is connected to the rotating portion 132 and extends downward from the right side of the blower 13, and an outer conduit 142 that extends to the right from the lower end. connecting pipe 141. The connecting pipe 141 and the outer pipe 142 can be attached to each other.

[0048] Part 16 for obtaining pressure data

[0049] The pressure data receiving portion 16 is a component that is connected to the air supply line 14 to obtain pressure data of the air supplied to the air supply components 13 and 14. The pressure data acquisition component 16 may be an atmospheric pressure sensor (APS), but its type is not limited to this. The pressure data receiving portion 16 may be coupled to the outer conduit 142 to receive air pressure data that is passed through the outer conduit 142 and supplied externally to the blower fan 13. The pressure data receiving portion 16 may transmit the resulting pressure to the processor. .

[0050] Processor

[0051] A processor is a component including an element that can perform logical operations to execute a control command, and may include a central processing unit (CPU). The processor may be coupled to the elements to transmit signals for control in accordance with control commands to the element, and may be connected to sensors and data acquisition means to receive the received information in the form of signals. Accordingly, in an embodiment of the present invention, the processor may be electrically coupled to various elements included in the water heating device 1. Since the processor may be electrically coupled to the elements, it may be wiredly connected to the elements or may further include a communication module that can carry out wireless communication for mutual communication.

[0052] The burner 10 may further include a storage medium, wherein control instructions executed by the processor may be stored on the storage medium being used. The storage medium may be a device such as a hard disk drive (HDD), a solid state drive (SSD), a server, volatile storage media, or non-volatile storage media, but the types of storage media are not limited to these. In addition, the storage medium may further store data necessary for the processor to perform an operation.

[0053] The processor may be electrically coupled to air supply portions 13 and 14 and pressure data acquisition portion 16. Here, the electrical connection includes a physical connection for current flow and a communication connection for transmitting and receiving control signals.

[0054] The processor may control the rotation speed of the blower fan 13 based on the pressure value obtained by the pressure data acquisition portion 16 and a predetermined reference pressure. The processor may control the blower fan 13 so that the rotation speed of the blower fan 13 increases when the pressure value obtained by the pressure data acquisition portion 16 is lower than a predetermined reference pressure. When negative pressure occurs in the long gas pipeline, the pressure of the air supplied to the blower fan 13 decreases, and therefore a separation phenomenon may occur. Accordingly, in this case, since a higher air flow rate is supplied by controlling the processor so that the blower fan 13 rotates more, pressure conditions may arise in which the lifting phenomenon does not occur, and normal combustion can be ensured, that is, conditions may arise where similar to reference pressure. Conversely, the processor may control the blower fan 13 so that the rotation speed of the blower fan 13 is decreased when the pressure value obtained by the pressure data acquisition portion 16 is an excessively high pressure value.

[0055] The reference pressure value may be a set value. The processor may, as the reference pressure value, set the pressure value obtained by the pressure data acquisition portion 16 when the operation of the air supply components 13 and 14 is stopped and started again.

[0056] Part 12, 15, 17 and 18 for fuel supply

[0057] The fuel supply parts 12, 15, 17 and 18 are a component that supplies fuel for the combustion reaction and can supply fuel to the combustion space, which is the interior region of the combustion chamber 20. The fuel supplied by the fuel supply portions 12, 15, 17 and 18 may be gaseous in the form of combustible gas.

[0058] The fuel supply portions 12, 15, 17 and 18 may include a fuel injector 12. The fuel injector 12 is a fuel discharging assembly. A plurality of fuel injectors 12 may be provided. A plurality of fuel injectors 12 may be provided which can reduce the amount of nitrogen oxide emissions by producing a split flame. A plurality of fuel injectors 12 may be spaced apart surrounding a centrally located fuel injector 12, with the fuel injector 12 located at the center when viewed in a reference direction. A plurality of fuel injectors 12 may be positioned at the same angle, with the center being the ignition portion 19. Accordingly, when viewed in the reference direction, the figure obtained by connecting the locations of the plurality of fuel injectors 12 may be a regular polygon.

[0059] The fuel supply portions 12, 15, 17, and 18 may include a fuel valve 15. The fuel supply portions 12, 15, 17, and 18 may include a valve supply line 17 for supplying fuel stored in the fuel tank , to the fuel valve 15. The fuel supply portions 12, 15, 17 and 18 may include an injector supply line 18 for supplying fuel exiting the fuel valve 15 to the fuel injector 12. As shown, the valve supply line 17 may include a first valve supply line 171 connected to the fuel reservoir, and a plurality of second valve supply lines 172 into which the first valve supply line 171 branches and which supply fuel to a plurality of fuel valves 15. The injector supply line 18 may include a first injector supply line 181 collecting at one location fuel exiting the plurality of fuel valves 15, and a second injector supply line 182 extending to the fuel injector 12 from the first injector supply line 181.

[0060] The fuel valve 15 may control the flow rate of fuel supplied to the combustion chamber 20. The fuel valve 15 can control the flow rate of fuel supplied to the combustion chamber 20 in accordance with the pressure in the combustion chamber 20.

[0061] In FIG. 4 is a conceptual view of a water heating device system 100 according to one embodiment of the present invention.

[0062] As shown in the drawing, the water heating device system 100 according to one embodiment of the present invention may include a plurality of water heating devices 1a and 1b. The plurality of water heating devices 1a and 1b may be the same as the water heating device 1 disclosed above, and may be the first water heating device 1a and the second water heating device 1b, respectively. The first water heating device 1a and the second water heating device 1b may be connected to the common gas pipeline 101 through the first gas pipeline 102 and the second gas pipeline 103. When the first water heating device 1a is operating and the second water heating device 1b is not operating, the internal pressure in the combustion chamber 20 of the second water heating device 1b may increase due to combustion gases exiting the first water heating device 1a. In this case, the flow rate of fuel supplied to the second water heating device 1b will be lower than the air flow rate, and therefore the ratio of fuel to normal air cannot be maintained, and as a result, smooth combustion may not be ensured.

[0063] In FIG. 5 is a view illustrating the fuel valve 15 of the burner 10 according to one embodiment of the present invention. In fig. 6 is a view illustrating the fuel valve 15 of FIG. 5, while its fragment is missing and its internal structure is visible. In fig. 7 is a view illustrating the feedback port 156, the fuel chamber 153, and the valve port 155 of the fuel valve 15 of FIG. 5.

[0064] The fuel supply parts 12, 15, 17 and 18 according to the embodiment can solve the above problem by controlling the opening degree of the fuel valve 15 in accordance with the pressure in the combustion chamber 20. The fuel supply portions 12, 15, 17, and 18 may include a pressure supply line that communicates with an interior region of the combustion chamber 20 and is connected to the fuel valve 15 to control the opening degree of the fuel valve 15 in accordance with the pressure in the combustion chamber 20. The internal pressure in the combustion chamber 20 is supplied to the fuel valve 15 through a pressure supply line to provide feedback control. One end of the pressure supply conduit may be connected to the feedback port 156, and the opposite end thereof may be located within the blower pipe 112 to supply the internal pressure of the combustion chamber 20 to the fuel valve 15.

[0065] Fuel valve 15 may include a feedback port 156, a fuel chamber 153, and a valve port 155. The fuel valve 15 may include a supply chamber 151 and an opening/closing chamber 152.

[0066] Fuel supplied to the fuel valve 15 through the valve supply line 17 may be introduced into the supply chamber 151. The supply chamber 151 may be connected to the opening/closing chamber 152 to supply fuel to the opening/closing chamber 152. The opening/closing chamber 152 may include an opening/closing valve body. The opening connected to the fuel chamber 153 can be opened and closed by the opening/closing valve body in accordance with control from the processor. Accordingly, the control of the supply or lack of supply of fuel can be carried out by the opening/closing camera 152.

[0067] The fuel chamber 153 may receive fuel from the opening/closing chamber 152 and may discharge fuel through a fuel port connected to the injector supply line 18 . That is, the fuel hole may be connected to the fuel injector 12 and the combustion chamber 20 via an injector supply line 18. Valve port 155 can open and close the fuel port. Valve port 155 may be coupled to a pressure supply line to be actuated by the differential pressure of feedback port 156, which receives pressure fluid in combustion chamber 20 and fuel chamber 153. Fuel valve 15 may include feedback port 156 coupled to the line. pressure supply and fuel chamber 153.

[0068] Without feedback control, when the pressure in the combustion chamber 20 is high, less fuel is supplied than when the pressure in the combustion chamber 20 is lower, and therefore it is difficult to maintain the ratio of fuel to normal air. Since, as in the embodiment of the present invention, a fuel valve 15 is provided to compensate for this, valve port 155 can open the fuel port at a higher opening ratio when the pressure in the combustion chamber 20 is higher, and can open the fuel port at a lower opening ratio when the pressure in the combustion chamber 20 is lower. Accordingly, in the water heating device 1 according to an embodiment of the present invention, by using the fuel valve 15, more fuel can be supplied to the combustion chamber 20 when the pressure in the combustion chamber 20 is higher than when the pressure in the combustion chamber 20 is lower, and therefore can be maintained ratio of fuel to normal air.

[0069] A plurality of fuel valves 15 may be provided, as shown in the drawing, which may be connected in parallel to each other. Indicating that the fuel valves 15 are connected in parallel to each other means that the fuel valves 15 are not connected directly in series with each other with fuel supplied from the same valve supply line 17 to the same outlet line 18 . Since the fuel valves 15 are connected in parallel to each other to control them, not a fixed amount of fuel is supplied, but precise proportional control of the amount of fuel is possible, whereby proportional control is possible and therefore the state of ignition and combustion can be maintained at a low heat amount. Since ignition is possible at a low amount of heat due to the parallel valve design, a low ignition pressure is generated, as a result of which the dynamic effect on the other part communicating with the combustion chamber 20 and the other water heating device connected by a common gas pipeline can be reduced, and the burning noise. In addition, since a plurality of low-cost low-flow valves can be used, an economical fuel supply design can be obtained as compared to the case where a single expensive high-flow valve is used.

[0070] Accordingly, since it is possible to properly control the blower depending on the load under the operating conditions of the burner, stable ignition and reduction of the lift-off phenomenon are possible, whereby stable combustion can be achieved.

[0071] Although all elements constituting the embodiments of the present invention have been disclosed heretofore to be linked together or linked to control them, the present invention is not substantially limited to these embodiments. That is, without departing from the purpose of the present invention, all elements can be selectively linked into one or more elements to be controlled. In addition, since terms such as “comprising,” “including,” or “having” may imply that the corresponding element may be included, it should be construed, unless specifically stated otherwise, that another element is not excluded but may additionally included in the composition. Moreover, unless otherwise indicated, all terms used herein, including technical or scientific terms, have the same meanings as commonly understood by those skilled in the art to which the present invention relates. Terms, such as those defined in commonly used dictionaries, should be construed to coincide with the contextual meanings of the relevant technologies and should not be construed in an abstract or overly formal sense unless explicitly stated in the disclosure of the present invention.
