[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0042] In the description of the present application, it should be understood that the terms "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, "multiple" means two or more, and at least one means one, two or more, unless otherwise clearly and specifically defined. In the description of this application, "vertical" means completely vertical at 90° or almost completely vertical, for example, an angle within the range of 80° to 100° is considered vertical. Similarly, "parallel" means completely parallel or almost completely parallel, for example, an angle within 10° of completely parallel is considered parallel.

[0043] During the transport process, liquefied natural gas (LNG) carriers generate boil-off gas (BOG), which is vaporized LNG. This gas increases cargo tank pressure. Natural gas incineration devices treat BOG by burning it to control tank pressure. Depending on operating conditions, BOG may contain varying concentrations of nitrogen. High nitrogen concentrations prevent BOG from sustaining combustion, necessitating the use of combustion-supporting devices.

[0044] Natural gas incineration devices usually use spark ignition or diesel ignition to achieve combustion of BOG gas. However, both spark ignition and diesel ignition have significant technical drawbacks.

[0045] Spark ignition uses a high-voltage or high-energy ignition gun to generate an arc, which ignites the BOG gas. The main drawbacks of this method are: 1. It cannot handle nitrogen-containing BOG gas, and will not burn when the nitrogen concentration reaches 60%; 2. Prolonged power generation can easily cause damage, making it unusable as a permanent lamp; 3. The high discharge voltage of the igniter poses a high risk of damage.

[0046] The diesel ignition and combustion-assisted method uses an electric spark to ignite diesel, which then ignites the BOG gas. This method overcomes the shortcomings of electric spark ignition, but its main drawbacks are: 1. It consumes diesel; 2. The equipment is more complex, requiring not only an electric spark igniter but also an oil pump unit; 3. The diesel nozzle is easily contaminated, making the system prone to failure.

[0047] In view of this, embodiments of the present application provide a burner and a gas incineration device, aiming to solve at least one of the above-mentioned problems.

[0048] Please refer to Figure 1-Figure 3 An embodiment of the present application provides a burner, including a shell 1, a fuel gas delivery assembly 2 and an ignition assembly 3, the shell 1 has a chamber 11 and an air outlet 12, the chamber 11 is connected to the air outlet 12; the fuel gas delivery assembly 2 is arranged in the chamber 11 and is connected to the shell 1; the fuel gas delivery assembly 2 includes a plurality of fuel gas nozzles 21, the plurality of fuel gas nozzles 21 are arranged at the air outlet 12, and the plurality of fuel gas nozzles 21 are arranged at circumferential intervals around the air outlet 12; the ignition assembly 3 is arranged in the chamber 11 and is connected to the shell 1, the ignition assembly 3 includes a heating element 31, the heating element 31 is arranged at the air outlet 12, and is located between the plurality of fuel gas nozzles 21; the heating element 31 is arranged at intervals from the plurality of fuel gas nozzles 21.

[0049] In the embodiment of the present application, the burner can be applied to a marine gas combustion device. By arranging a heating element 31 between multiple fuel gas nozzles 21, the heating element 31 is energized and converts electrical energy into thermal energy. The fuel gas nozzle 21 sprays the fuel gas toward the heating element 31 and contacts the heating element 31, so that the fuel gas ejected from multiple nozzles is heated by the heating element 31, and the fuel gas is continuously burned after reaching the ignition point of the fuel gas. By continuously energizing the heating element, the fuel gas can be continuously assisted in combustion, thereby improving the combustion effect of the fuel gas. In addition, compared with traditional electric spark ignition and diesel ignition combustion-assisted burners, the burner of the embodiment of the present application is simple in overall equipment and easy to operate. It can be used by simply turning on the power. At the same time, the heating element 31 has a long service life and low maintenance requirements. It can also be used as a long-lasting lamp to continuously assist in the combustion of the fuel gas, thereby improving the burner's combustion processing capacity for nitrogen-containing dye gas.

[0050] It should be noted that the embodiments of the present application can process both nitrogen-free BOG gas and nitrogen-containing BOG gas. Therefore, the fuel gas in the embodiments of the present application can be both nitrogen-free BOG gas and nitrogen-containing BOG gas. Moreover, the fuel gas can have a good combustion-supporting ability for BOG gas with a higher nitrogen concentration, thereby improving the combustion treatment effect of nitrogen-containing BOG gas and reducing air pollution.

[0051] Please refer to Figure 7-Figure 9 In some embodiments, the ignition assembly 3 includes a plurality of heating elements 31 , and the plurality of heating elements 31 are arranged at intervals and between the plurality of fuel gas nozzles 21 .

[0052] In the embodiment of the present application, by providing multiple heating elements 31, the distance between the fuel gas nozzle 21 and the heating element 31 can be shortened, and the overall heating area of ​​the ignition component 3 is increased, thereby improving the heating and combustion-supporting capacity of the ignition component 3, which is more conducive to the sufficient heating and combustion of the nitrogen-containing fuel gas.

[0053] Please refer to Figure 7-Figure 9 In some embodiments, the plurality of heating elements 31 are arranged at equal intervals in the axial direction around the air outlet 12 , and the plurality of heating elements 31 are conductively connected.

[0054] In the embodiment of the present application, multiple heating elements 31 are arranged at equal intervals axially around the gas outlet 12. In this case, the multiple heating elements 31 are evenly distributed, and each heating element 31 can radiate the same amount of fuel gas nozzle 21, thereby further improving the overall heating and combustion-supporting effect of the ignition assembly 3 on the fuel gas. In addition, the multiple heating elements 31 are electrically connected. In this case, the multiple heating elements 31 can be electrically connected to a heating circuit, thereby achieving heating by energizing the heating elements 31. Specifically, the multiple heating elements 31 can be connected in parallel or in series.

[0055] Please refer to Figure 7-Figure 9 In some embodiments, the ignition assembly 3 includes a connecting rod 33 and multiple fixed supports 32, the multiple fixed supports 32 are connected to the multiple heating elements 31 in a one-to-one correspondence, and the fixed support 32 has a first channel 321; the connecting rod 33 is arranged on the side of the fixed support 32 away from the heating element 31, and one end of each fixed support 32 away from the heating element 31 is connected to the connecting rod 33, and one end of the connecting rod 33 away from the fixed support 32 is connected to the shell 1 and passes through the outside of the shell 1; the connecting rod 33 has a second channel 331, and the first channels 321 of the multiple fixed supports 32 are all connected to the second channel 331.

[0056] In an embodiment of the present application, a connecting rod 33 and a plurality of fixed supports 32 are provided, and the connecting rod 33 is used to connect to the shell 1, so that the plurality of fixed supports 32 and the plurality of heating elements 31 are supported in a space surrounded by a plurality of fuel gas nozzles 21, thereby realizing a close arrangement of the heating elements 31 and the fuel gas nozzles 21, wherein the plurality of fixed supports 32 are used to extend outward in a divergent manner in a direction away from the connecting rod 33, and the angles between two adjacent fixed supports 32 are the same, thereby realizing the equal spacing of the plurality of heating elements 31.

[0057] In addition, the fixed support 32 of the embodiment of the present application is provided with a first channel 321, and the connecting rod 33 is provided with a second channel 331. At this time, the wire 8 connected to the heating element 31 can pass through the first channel 321 and the second channel 331 in sequence and finally pass out to the outside of the shell 1 for conductive connection with the external power supply device to realize power supply of the heating element 31.

[0058] It should be noted that the heating element 31 of the embodiment of the present application can be ignited by setting an ignition controller 9 on the outside of the shell 1. The ignition controller 9 is conductively connected to the heating element 31 through a wire 8. The ignition controller 9 is used to receive a 220V external power supply and convert it into the voltage required by the heating element 31, thereby achieving smooth heating and combustion of the heating element 31. At the same time, the ignition controller 9 can control the heating temperature of the heating element 31 by controlling the voltage of the heating element 31.

[0059] It should also be noted that when there is only one heating element 31, Figure 3 and Figure 5 As shown, the connecting rod 33 can be directly connected to the heating element 31. By providing the connecting rod 33, the present application can achieve isolation protection for the wire 8, effectively preventing the wire 8 from being burned in the burner.

[0060] Please refer to Figure 7-Figure 9 In some embodiments, along the axial direction of the air outlet 12 , one end of the fixing support 32 connected to the heating element 31 is bent in a direction away from the connecting rod 33 .

[0061] In the embodiment of the present application, by setting the fixed support 32 as a bent structure, on the one hand, the heating element 31 can be extended axially along the air outlet 12, thereby facilitating increasing the contact area between the heating element 31 and the fuel gas ejected from the fuel gas nozzle 21; at the same time, during the process of heating, burning and flowing of the fuel gas toward the air outlet 12, the fuel gas can continue to be in contact with and heated by the heating element 31, thereby further improving the heating and combustion-supporting effect of the heating element 31 on the fuel gas, and thereby improving the combustion treatment effect of the fuel gas.

[0062] Please refer to Figure 7-Figure 9 In some embodiments, the ignition assembly 3 further includes a positioning bracket 34, which includes a support rod 341 and a plurality of positioning members 342; the support rod 341 is connected to the connecting rod 33, and the plurality of positioning members 342 are connected to one end of the support rod 341 away from the connecting rod 33, and the end of the positioning member 342 away from the support rod 341 is connected to the end of the fixed support 32 away from the connecting rod 33.

[0063] In the embodiment of the present application, by providing a positioning bracket 34, it is possible to effectively position and support the end of the fixed support 32 away from the connecting rod 33, thereby improving the stability of the position positioning of the fixed support 32 and effectively preventing the end of the fixed support 32 away from the connecting rod 33 from bending and deforming under the action of gravity and the pressure of the heating element 31.

[0064] Please refer to Figure 8 and Figure 9In some embodiments, a positioning ring 3421 is provided at one end of the positioning member 342 away from the support rod 341 , and the positioning ring 3421 is sleeved on the outer side of the end of the fixed support 32 away from the connecting rod 33 .

[0065] In the embodiment of the present application, by providing a positioning ring 3421 that is directly sleeved on the outside of the fixed support 32, on the one hand, it is beneficial to achieve the connection between the positioning member 342 and the fixed support 32. On the other hand, by wrapping the positioning ring 3421 around the outside of the fixed support 32, it can ensure that there is sufficient contact area between the positioning member 342 and the fixed support 32, thereby ensuring the connection effect between the positioning member 342 and the fixed support 32, ensuring the stability of the connection support of the positioning member 342, and avoiding damage to the fixed support 32.

[0066] Please refer to Figure 3 、 Figure 6 and Figure 7 In some embodiments, the fuel gas delivery assembly 2 further includes an intake pipe 22, a collecting pipe 23 and a plurality of branch pipes 24.

The end of the branch pipe 24 away from the collecting pipe 23 is connected to the fuel gas nozzle 21.

[0067] In the embodiment of the present application, the air inlet pipe 22 is used to transport the fuel gas from the outside of the burner shell 1 to the manifold 23. The manifold 23 is used to disperse the fuel gas into multiple branch pipes 24. The fuel gas is then sprayed into the chamber 11 by the fuel gas nozzles 21 connected via the multiple branch pipes 24 for heating and combustion. The provision of an annular manifold 23 allows multiple branch pipes 24 to be arranged around the ignition assembly 3, thereby enabling multiple fuel gas nozzles 21 to be arranged around the ignition assembly 3. This facilitates the heating element 31 of the ignition assembly 3 to heat the fuel gas ejected from the multiple fuel gas nozzles 21 on the outer periphery and cause the fuel gas to burn, thereby achieving a higher combustion-supporting effect.

[0068] Please refer to Figure 1-Figure 3 and Figure 7 In some embodiments, the burner further includes an air collecting plate 4 , which is arranged around the outer periphery of the air outlet 12 and connected to the shell 1 .

[0071] In the embodiment of the present application, by providing a combustion-supporting gas inlet 13 and a first flow equalizing member 5, the combustion-supporting gas can be first introduced into the air inlet chamber 111 and flow in the air inlet chamber 111. The air inlet chamber 111 is an annular structure, and the combustion-supporting gas flows in the annular air inlet chamber 111. At this time, the first flow equalization of the combustion-supporting gas can be achieved in the air inlet chamber 111; the combustion-supporting gas is then separated and enters the flow equalizing chamber 112 through the flow equalizing hole 51 on the first flow equalizing member 5, and the second flow equalization of the combustion-supporting gas is achieved. At this time, the combustion-supporting gas is mixed with the fuel gas sprayed from multiple fuel gas nozzles 21, and a more uniform mixing of the fuel gas and the combustion-supporting gas can be achieved, thereby improving the combustion effect of the fuel gas.

[0072] It should be noted that the combustion-supporting gas in the embodiment of the present application may be air.

[0074] In the embodiment of the present application, by providing a second flow equalizer 6, the combustion-supporting gas passes through the second flow equalizer 6 and reaches the vicinity of the fuel gas nozzle 21. At this time, the third flow equalization of the combustion-supporting gas can be achieved, thereby further improving the uniformity of the mixing of the fuel gas and the combustion-supporting gas.

[0075] It should be noted that in the embodiment of the present application, multiple flow equalizing plates 61 are arranged at intervals and have the same axial inclination angle relative to the air outlet 12. At this time, the multiple flow equalizing plates 61 of the second flow equalizing member 6 can be swirl blades, which can not only divide the oxidizing gas again through the multiple flow equalizing plates 61, but also use the flow equalizing plates 61 to change the direction of the oxidizing gas.
