Description

Technical Field

[0001] This utility model belongs to the field of burner technology and relates to a partitioned segmented burner. Background Technology

[0002] In various applications of burners, including industrial heating, household gas appliances, and commercial kitchen equipment, different operating conditions demand diverse ranges of adjustable heating power. Traditional burners mostly employ a single combustion mode or a limited number of fixed combustion modes, failing to flexibly adapt to complex and changing usage scenarios. For example, in industrial production, different processing stages may require different heating powers, which traditional burners struggle to precisely match, leading to increased energy consumption and reduced production efficiency. In household gas appliances, cooking different foods requires different heat levels, which traditional burners cannot precisely adjust, affecting cooking results. Furthermore, due to the inability to effectively control the number of combustion holes, incomplete combustion of gas is prone to occur at low power operation, causing environmental pollution and energy waste. Therefore, there is an urgent need to develop a segmented burner with a row of combustion holes that can flexibly adjust the number of working combustion holes and broaden the range of adjustable heating power.

[0003] To overcome the shortcomings of existing technologies, various solutions have been proposed through continuous exploration. For example, a Chinese patent discloses an atmospheric segmented burner and hot water equipment [Application No.: 202023313891.6]. During operation, the gas is ejected through a nozzle, entraining surrounding air into the ejector for mixing; then, it is injected into the ejector port and flows into the mixing tank. The gas entering the mixing tank is mixed again, ensuring thorough mixing of the gas and air and improving the uniformity of the mixture. After mixing, the gas flows into the equalization chamber through the equalization orifice, and then flows to the flame orifice, allowing the mixed gas to flow out of the burner body surface for ignition. However, this solution still cannot flexibly adjust the number of working flame orifices or broaden the heating power adjustment range during use, resulting in high energy consumption. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing a segmented burner with alternating rows.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A segmented burner includes a burner body and a burner distribution pipe. The burner distribution pipe has two parallel channels for connecting to outside air. One end of each channel is connected to a first nozzle section, a second nozzle section, and a third nozzle section, and the other end is connected to a first air inlet section, a second air inlet section, and a third air inlet section. The burner body and the burner distribution pipe are connected by a connector. The burner body is composed of a first combustion plate group, a second combustion plate group, and a third combustion plate group arranged in parallel. The first nozzle section corresponds to the first air inlet section and the first combustion plate group, the second nozzle section corresponds to the second air inlet section and the second combustion plate group, and the third nozzle section corresponds to the third air inlet section and the third combustion plate group.

[0007] In the above-mentioned segmented burner, the first combustion plate group includes two first combustion plates, which are parallel to each other, and the first combustion plates are connected to the first nozzle section.

[0008] In the above-mentioned segmented burner, the first nozzle section includes two first nozzles disposed on the burner distribution pipe. The first nozzles are connected to the first combustion plates through a connecting valve, and the two first combustion plates are parallel to each other.

[0010] In the above-mentioned segmented burner, the second combustion plate group includes three second combustion plates, which are parallel to each other, and the second combustion plates are connected to the second nozzle section.

[0011] In the above-mentioned segmented burner, the second nozzle section includes three second nozzles disposed on the burner distribution pipe. The second nozzles are connected to the second combustion plate through a connecting valve, and the three second nozzles are parallel to each other.

[0012] In the above-mentioned segmented burner, the second air intake section includes a second air inlet and a second air intake pipe disposed at the bottom of the burner distribution pipe, and the second air intake pipe is connected to the channel.

[0013] In the above-mentioned segmented burner, the third combustion plate group includes six third combustion plates, which are parallel to each other, and the third combustion plates are connected to the third nozzle section.

The third air intake section includes a third air inlet and a third air intake pipe disposed at the bottom of the burner distribution pipe. The third air intake pipe is connected to the channel.

[0015] In the above-mentioned segmented burner, the connecting component includes a connecting bracket disposed between the burner body and the burner distribution pipe. The burner distribution pipe is provided with a fixed screw profile at the end away from the burner body. The burner body is provided with a dust shield and an air damper fixing plate. The burner body is located above the burner distribution pipe.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1. In use, this utility model can achieve three combustion modes (2 rows, 5 rows, and 11 rows) by setting three air intake pipes and different numbers of combustion plate groups. It can accurately control the number of combustion holes participating in combustion according to actual needs, effectively expanding the range of heating power adjustment. For example, in scenarios with low power demand, only the 2 rows of burners corresponding to the first combustion plate group can be turned on for combustion, avoiding energy waste; while in scenarios with high power demand, all 11 rows of burners can be turned on to meet high-intensity heating needs.

[0018] 2. By setting up components such as connecting brackets, fixed screw profiles, dirt shields, and damper fixing plates, this utility model not only ensures a stable connection between the main body of the burner and the burner distribution pipe, but also prevents impurities from entering the burner and ensures the normal operation of the burner. The damper fixing plate facilitates the adjustment of the air intake volume, further optimizing the combustion effect.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, a segmented burner includes a burner body 1 and a burner distribution pipe 2. The burner distribution pipe 2 has two parallel channels 3 for connecting to the outside air. One end of each channel 3 is connected to a first nozzle section 4, a second nozzle section 5, and a third nozzle section 6, and the other end is connected to a first air intake section 7, a second air intake section 8, and a third air intake section 9. The burner body 1 and the burner distribution pipe 2 are connected by a connector 10. The burner body 1 is composed of a first combustion plate group 11, a second combustion plate group 12, and a third combustion plate group 13 arranged in parallel. The first nozzle section 4 corresponds to the first air intake section 7 and the first combustion plate group 11, the second nozzle section 5 corresponds to the second air intake section 8 and the second combustion plate group 12, and the third nozzle section 6 corresponds to the third air intake section 9 and the third combustion plate group 13.

[0027] In this embodiment, the burner distribution pipe 2 serves as the core component for gas and air transmission in the entire burner. Two parallel channels 3 within it are responsible for delivering air to the corresponding nozzle sections. The first air intake 7, the second air intake 8, and the third air intake 9 introduce outside air into the channels 3, which then transmit the air to the first nozzle section 4, the second nozzle section 5, and the third nozzle section 6. The burner body 1 is mounted above the burner distribution pipe 2 via a connector 10. The first combustion plate group 11, the second combustion plate group 12, and the third combustion plate group 13 are arranged in parallel, each corresponding to a nozzle section and air intake section at a specific location, forming an independent yet coordinated combustion unit. This achieves the orderly distribution of gas and air, laying the foundation for different combustion modes. By cooperating with the corresponding combustion plate groups through three independent air intake paths, the number of combustion plates participating in combustion can be flexibly controlled, thereby achieving preliminary adjustment of the combustion power and meeting the heating requirements in different scenarios.

[0028] Combination Figure 1-4As shown, the first combustion plate assembly 11 includes two first combustion plates 14, which are parallel to each other, and the first combustion plates 14 are connected to the first nozzle portion 4.

[0029] Specifically, two parallel first combustion plates 14 form a first combustion plate group 11, which is connected to the first nozzle section 4 through a pipe or connecting structure. The first nozzle section 4 delivers a mixture of gas and air to the first combustion plates 14. The first combustion plates 14 are provided with combustion holes, from which the mixture is ejected and burned. The two first combustion plates 14 form a basic combustion unit, providing a stable combustion surface. In low-power combustion mode, only the first combustion plate group 11 needs to be turned on to meet the requirements, achieving energy saving and precise heating. At the same time, the parallel arrangement of the first combustion plates 14 makes the combustion more uniform and improves the combustion effect.

[0030] The first nozzle section 4 includes two first nozzles 15 disposed on the burner distribution pipe 2. The first nozzles 15 are connected to the first combustion plate 14 through a connecting valve, and the two first combustion plates 14 are parallel to each other.

[0031] In this embodiment, two first nozzles 15 are installed on the burner distribution pipe 2 and communicate with the channel 3 to export the gas-air mixture in the channel 3. The first nozzles 15 are connected to the first combustion plate 14 through a connecting valve. The connecting valve can control the flow of the gas mixture. When the connecting valve is open, the gas mixture enters the first combustion plate 14 from the first nozzles 15; when it is closed, the gas mixture supply is cut off. The connecting valve enables precise control over whether the first combustion plate assembly 11 is burning, thereby enabling the switching of different combustion modes. When low-power operation is required, the connecting valve is opened to make the first combustion plate assembly 11 work; when not needed, it is closed to avoid gas waste. At the same time, the two first nozzles 15 ensure that the gas mixture is evenly distributed to the two first combustion plates 14, ensuring combustion stability.

[0032] Combination Figure 1 , Figure 4 As shown, the first air intake 7 includes a first air inlet 16 and a first air intake pipe 17 disposed at the bottom of the burner distribution pipe 2, and the first air intake pipe 17 is connected to the channel 3.

[0033] In this embodiment, the first air inlet 16 is located at the bottom of the burner distribution pipe 2. Outside air enters the first air inlet pipe 17 through the first air inlet 16. The first air inlet pipe 17 introduces air into the channel 3 inside the burner distribution pipe 2, providing the oxygen required for gas combustion. This ensures that air can enter the combustion system stably and smoothly, providing sufficient oxygen for the combustion of the first combustion plate group 11 and ensuring complete combustion. At the same time, the independent first air inlet 7 corresponds to the first combustion plate group 11, so that when adjusting the operation of the first combustion plate group 11, its air intake can be precisely controlled to optimize the combustion effect.

[0034] The second combustion plate assembly 12 includes three second combustion plates 18, which are parallel to each other, and the second combustion plates 18 are connected to the second nozzle portion 5.

[0035] In this embodiment, three parallel second combustion plates 18 constitute a second combustion plate group 12. They are connected to the second nozzle section 5 through pipes or connecting structures. The second nozzle section 5 delivers the gas-air mixture to the second combustion plates 18, and the combustion holes on the second combustion plates 18 spray out the mixture for combustion. The three second combustion plates 18 increase the combustion area, and in the medium power combustion mode (the first combustion plate group 11 and the second combustion plate group 12 work together), they can provide greater combustion power to meet the needs of more scenarios. The parallel arrangement ensures the uniformity and stability of combustion, and at the same time, working in coordination with the first combustion plate group 11, it realizes the step-wise adjustment of combustion power.

[0036] Combination Figure 1 , Figure 4 As shown, the second nozzle section 5 includes three second nozzles 19 disposed on the burner distribution pipe 2. The second nozzles 19 are connected to the second combustion plate 18 through a connecting valve, and the three second nozzles 19 are parallel to each other.

[0037] In this embodiment, three second nozzles 19 are installed on the burner distribution pipe 2 and connected to the channel 3 to export the gas-air mixture in the channel 3. Each second nozzle 19 is connected to the corresponding second combustion plate 18 through a connecting valve. The connecting valve controls the on / off of the gas mixture, realizing independent control of the combustion of each second combustion plate 18. The combination of the connecting valve and the three second nozzles 19 not only realizes the control of whether the second combustion plate group 12 is burned as a whole, but also controls the individual second combustion plate 18, further refining the combustion mode adjustment. Under different power requirements, different numbers of second combustion plates 18 can be flexibly opened to achieve more precise power adjustment, while ensuring uniform distribution of the gas mixture and improving combustion stability.

[0038] The second air intake section 8 includes a second air inlet 20 and a second air intake pipe 21 located at the bottom of the burner distribution pipe 2, and the second air intake pipe 21 is connected to the channel 3.

[0039] In this embodiment, the second air inlet 20 is located at the bottom of the burner distribution pipe 2. Outside air enters the second air inlet pipe 21 through the second air inlet 20. The second air inlet pipe 21 introduces air into the channel 3 to provide oxygen for the combustion of the second combustion plate group 12. The independent second air inlet 8 corresponds to the second combustion plate group 12, ensuring the air supply required for the combustion of the second combustion plate group 12, so that the combustion is complete. When adjusting the working state of the second combustion plate group 12, its air intake can be precisely controlled. Working in coordination with the first air inlet 7, it can achieve precise adjustment of the overall air intake under different combustion modes and optimize combustion efficiency.

[0040] Combination Figure 1-4 As shown, the third combustion plate group 13 includes six third combustion plates 22, which are parallel to each other, and the third combustion plates 22 are connected to the third nozzle part 6.

[0041] In this embodiment, six parallel third combustion plates 22 form a third combustion plate group 13. They are connected to the third nozzle section 6 through pipes or connecting structures. The third nozzle section 6 delivers the gas-air mixture to the third combustion plates 22. The combustion holes on the third combustion plates 22 spray out the mixture for combustion. The six third combustion plates 22 significantly increase the combustion area. In the high-power combustion mode (the first combustion plate group 11, the second combustion plate group 12, and the third combustion plate group 13 work together), they can provide strong combustion power to meet the high-load heating requirements. The parallel arrangement ensures the uniformity and stability of the large-area combustion. In conjunction with the first and second combustion plate groups, it achieves comprehensive coverage and flexible adjustment of combustion power from low to high.

[0042] Combination Figure 1-4 As shown, the third nozzle section 6 includes six third nozzles 23 disposed on the burner distribution pipe 2. The third nozzles 23 are connected to the third combustion plate 22 through a connecting valve. The six third nozzles 23 are parallel to each other. The third air intake section 9 includes a third air inlet 24 and a third air intake pipe 25 disposed at the bottom of the burner distribution pipe 2. The third air intake pipe 25 is connected to the channel 3.

[0043] In this embodiment, six third nozzles 23 are installed on the burner distribution pipe 2 and connected to the channel 3 to export the gas-air mixture in the channel 3. Each third nozzle 23 is connected to the corresponding third combustion plate 22 through a connecting valve to control the flow of the gas mixture. The third air inlet 24 is located at the bottom of the burner distribution pipe 2. Outside air enters the third air inlet pipe 25 through the third air inlet 24 and then enters the channel 3 to provide oxygen for the combustion of the third combustion plate group 13. The combination of the six third nozzles 23 and the connecting valve realizes independent control of each combustion plate of the third combustion plate group 13. Combined with the control structure of the first and second combustion plate groups, it can realize the combination of various combustion modes, which greatly expands the power adjustment range of the burner. The independent third air inlet 9 ensures that there is sufficient air when the third combustion plate group 13 is burning. It works in coordination with other air inlets to ensure that the best combustion effect can be achieved in different combustion modes.

[0044] Combination Figure 1-4 As shown, the connector 10 includes a connecting bracket 26 disposed between the burner body 1 and the burner distribution pipe 2. The burner distribution pipe 2 is provided with a fixed screw profile 27 at the end away from the burner body 1. The burner body 1 is provided with a dirt baffle 28 and an air damper fixing plate 29. The burner body 1 is located above the burner distribution pipe 2.

[0045] In this embodiment, the connecting bracket 26 connects the burner body 1 and the burner distribution pipe 2, providing support and fixation, ensuring the burner body 1 is securely mounted above the burner distribution pipe 2. The fixing screw profile 27 is used to fix the burner as a whole to other equipment. The dust baffle 28 is installed on the burner body 1 to prevent external impurities from entering the burner. The damper fixing plate 29 is used to install the adjusting damper, controlling the amount of air entering the burner. The connecting bracket 26 and the fixing screw profile 27 ensure the stability of the burner structure and the convenience of installation. The dust baffle 28 effectively protects the internal structure of the burner, reduces the impact of impurities on combustion, and extends the burner's service life. The damper fixing plate 29 allows users to adjust the air intake according to actual needs, optimize combustion effect, and further improve the burner's adaptability and energy efficiency.

[0046] The working principle of this utility model is as follows:

[0047] This utility model's segmented burner has three air inlet pipes (corresponding to the first air inlet 7, the second air inlet 8, and the third air inlet 9) and 11 rows of burners (composed of two first combustion plates 14, three second combustion plates 18, and six third combustion plates 22), enabling three combustion modes. Each of the first combustion plates 14, second combustion plates 18, and third combustion plates 22 has a mixing channel, a connecting cavity, and a mixing chamber. The specific working steps are as follows:

[0048] 2-row burner combustion mode (low power mode): When the equipment is in a low-power heating demand scenario, only the first combustion plate group 11 needs to be activated. Gas enters the first intake pipe 17 through the first intake port 16. Since the first intake pipe 17 is connected to the channel 3 in the burner distribution pipe 2, the gas is transmitted to the first nozzle section 4 along the channel 3. At this time, the operator opens the connecting valve between the first nozzle 15 and the first combustion plate 14, and the mixed gas enters the first combustion plate 14 through the connecting valve. Inside the first combustion plate 14, the mixed gas first enters the mixing channel, and the mixing flow... The unique structural design of the combustion chamber allows for initial guidance and mixing of the fuel gas and air. The mixed gas then enters the connecting chamber, which acts as a transition and buffer, ensuring further uniform gas distribution. Finally, the mixed gas reaches the mixing chamber, where the fuel gas and air are thoroughly mixed to form a uniform and stable combustible mixture. After mixing, the combustible mixture is ejected and ignited from the combustion holes on the surface of the first combustion plate 14. Both first combustion plates 14 operate simultaneously, forming two rows of burners, thereby outputting low-power heat to meet low-intensity heating requirements.

[0049] 5-row combustion mode (medium power mode): When medium power heat output is required, the system simultaneously activates the first combustion plate group 11 and the second combustion plate group 12. The working process of the first air intake 7 is the same as in the low power mode. The gas enters the first combustion plate 14 through the first air intake port 16, the first air intake pipe 17, the channel 3, and the first nozzle 4, and completes combustion. At the same time, the second air intake 8 starts working. External gas enters the second air intake pipe 21 from the second air intake port 20, and then is transmitted to the second nozzle 5 along the channel 3. The operator opens the connecting valve between the second nozzle 19 and the second combustion plate 18, and the mixed gas enters the second combustion plate 18. The second combustion plate 18 is also equipped with a mixing channel, a connecting chamber, and a mixing chamber. The mixed gas passes through these structures in sequence to achieve full mixing before being ejected from the combustion hole for combustion. The three second combustion plates 18 and the two first combustion plates 14 work together to form a 5-row combustion system, enabling the burner to output medium power heat to meet medium intensity heating requirements.

[0050] 11-row combustor combustion mode (high-power mode): In high-power heating scenarios, the first air intake 7, the second air intake 8, and the third air intake 9 operate simultaneously. The gas delivery and combustion process of the first air intake 7 and the second air intake 8 is consistent with the above mode. The gas in the third air intake 9 enters the third air intake pipe 25 from the third air intake port 24, and is then transmitted to the third nozzle section 6 through the channel 3. After opening the connecting valve between the third nozzle 23 and the third combustion plate 22, the mixed gas enters the third combustion plate 22. The mixing channel, connecting chamber, and mixing chamber within the third combustion plate 22 thoroughly mix the mixed gas. Subsequently, the mixed gas is ejected from the combustion hole for combustion. All six third combustion plates 22, three second combustion plates 18, and two first combustion plates 14 are engaged, and the 11 rows of combustors burn simultaneously, generating a large amount of heat to achieve high-power output and meet high-intensity heating requirements.

[0051] Furthermore, throughout the combustion process, the operator can install and adjust the damper via the damper fixing plate 29 on the burner body 1. By changing the opening of the damper, the amount of air entering the channel 3 inside the burner distribution pipe 2 can be precisely controlled, thereby adjusting the mixing ratio of gas and air. Regardless of the combustion mode, the damper adjustment can ensure complete combustion of gas, improve combustion efficiency, reduce energy consumption and harmful gas emissions. At the same time, the baffle plate 28 can effectively block external dust, impurities and other contaminants from entering the burner, preventing these foreign objects from affecting the unobstructed flow of the combustion holes and the mixing effect of gas and air, ensuring the long-term stable and efficient operation of the burner.
