Description

Technical Field

[0001] This application relates to the field of combustion equipment technology, and more particularly to an ignition rod and a flare system having therein. Background Technology

[0002] In industries such as petroleum and chemical engineering, flare systems serve as crucial safety facilities. They are used to incinerate toxic and harmful waste gases emitted during normal production, accidents, or emergencies, rendering them harmless before release. The continuous flame lamp is a vital component of the flare system. Once ignited by the ignition rod, the continuous flame lamp can promptly ignite the exhaust gases reaching the flare, preventing personal injury and environmental pollution.

[0003] In related technologies, the ignition rod and the continuous lamp are fixed together by a threaded connection. However, because the flare system is under high temperature for a long time, the threads are prone to deformation, which reduces the connection strength between the ignition rod and the continuous lamp, affecting the stable operation of the flare system. Utility Model Content

[0004] This application provides an ignition rod that can ensure the stable operation of the flare system, thereby at least partially solving the above-mentioned technical problems.

[0005] To achieve the above objectives, according to a first aspect of this application, an ignition rod is provided, which, when energized, is capable of igniting a continuously lit lamp, the ignition rod comprising:

[0008] The mounting assembly includes a mounting member having a connecting portion connected to an extension member and a first mounting portion connected to a continuous lamp.

[0009] The first mounting portion protrudes from the radial end face of the connecting portion and is circumferentially arranged around the axis of the connecting portion.

[0010] Optionally, the ignition rod further includes a limiting member and an elastic member that cooperate with the mounting assembly. The elastic member has a first end and a second end that are opposite each other along the deformation direction. The first end abuts against the limiting member, and the second end abuts against the conductive member, so that the conductive member elastically abuts against the extension member.

[0011] Optionally, the conductive member has a conductive portion and a stop portion protruding from the radial end face of the conductive portion, the elastic member is sleeved on the conductive portion, and the second end abuts against the stop portion.

The locking member is sleeved on the mounting tube and abuts against the side of the stop block opposite to the elastic member.

[0015] Optionally, the limiting member includes a limiting tube sleeved on the conductive member and an mounting tube sleeved on the limiting tube, wherein the limiting tube is made of conductive material and the mounting tube is made of insulating material.

[0016] Optionally, a connecting adhesive layer is filled between the limiting tube and the mounting tube.

[0017] Optionally, the extension includes a conductive terminal abutting against the conductive element, the mounting assembly has a mounting cavity, the ignition rod has a protective tube located within the mounting cavity, the protective tube is sleeved at the abutment between the conductive terminal and the conductive element, and the protective tube is made of insulating material.

[0019] Optionally, the extension member includes a conductive core electrically connecting a conductive terminal to an ignition nozzle, and an extension tube sleeved around the outer periphery of the conductive core, wherein at least a portion of the ignition nozzle extends into the extension tube and is welded to the opening of the extension tube.

[0020] Optionally, the insulating material is alumina ceramic.

[0021] According to a second aspect of this application, a flare system is provided, comprising:

[0022] The lamp is always on and has a windproof cover.

[0023] As described above, in the ignition rod, at least a portion of the ignition nozzle is exposed inside the windproof cover;

[0024] The continuous light has a second mounting part, and the first mounting part and the second mounting part are configured as matching flanges. The first mounting part and the second mounting part are welded to each other or detachably connected.

[0025] Optionally, the continuous light includes a fuel pipe connected to the windshield, the second mounting part is connected to the fuel pipe, and the extension is inserted into the fuel pipe.

[0026] In the ignition rod of this application embodiment, since the first mounting part protrudes from the radial end face of the connecting part and is circumferentially arranged around the axis of the connecting part, the connection strength between the mounting part and the continuous lamp is increased, thereby improving the connection strength between the ignition rod and the continuous lamp and ensuring the stable operation of the torch system.

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0043] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0044] In the various figures of this application, for ease of illustration, certain dimensions of structures or parts may be exaggerated relative to other structures or parts; therefore, they are only used to illustrate the basic structure of the subject matter of this application.

[0045] refer to Figure 1 As shown in the figure, an embodiment of this application provides a torch system, including a continuous lamp 2 and an ignition rod 1.

[0046] In some embodiments, the ignition rod 1, when energized, can ignite the continuous lamp 2. In this embodiment, the continuous lamp 2 is located inside or near the torch head. The energized ignition rod 1 can ignite the continuous lamp 2, which then ignites the torch gas, thereby completing the torch ignition.

[0047] In some embodiments, the continuous lamp 2 has a windproof cover 21 that communicates with the outside air. In this embodiment, the fuel gas and air inside the continuous lamp 2 are mixed in the ejector 23 section, ignited by the ignition rod 1, and then burned at the windproof cover 21.

[0048] Reference Figure 2 and Figure 3 As shown, the ignition rod 1 includes a conductive element 11, an ignition assembly 12, and a mounting assembly 13. In this embodiment, the mounting assembly 13 is used to connect the conductive element 11 and the ignition assembly 12.

[0049] In some embodiments, the ignition assembly 12 includes an ignition nozzle 121 and an extension 122 electrically connecting the ignition nozzle 121 to the conductive member 11.

[0050] In this embodiment, the conductive component 11 is electrically connected to the positive terminal of the power supply via an external cable. When the fuel gas and air are mixed in a certain proportion in the ejector 23, ignition can be achieved using the igniter 121.

[0051] In this embodiment, the conductive element 11 can be made of a material that is resistant to high temperatures and has good electrical conductivity. When a voltage is applied to the conductive element 11, the electric field strength at the end of the conductive element 11 increases, generating a strong electric field.

[0052] In some embodiments, at least a portion of the ignition nozzle 121 is exposed within the windshield 21.

[0053] In this embodiment, since the current intensity and the electric field intensity are directly proportional, after the current passes through the conductive component 11 to the ignition nozzle 121, the ignition nozzle 121 is equivalent to a capacitor that charges and discharges rapidly, increasing the ignition energy. After the ignition nozzle 121 generates a discharge spark, it ignites at the wind shield 21.

[0054] In some embodiments, the mounting assembly 13 includes a mounting member 131. In this embodiment, the mounting member 131 is used to connect the extension member 122 and the continuous light 2.

[0055] In some embodiments, the mounting member 131 has a connecting portion 1311 connected to the extension member 122 and a first mounting portion 1312 connected to the continuous lamp 2.

[0056] In this embodiment, the extension 122 and the connecting part 1311 are welded together. The constant light 2 and the first mounting part 1312 can be connected in a detachable manner (for example, by means of a flange connection).

[0057] For example, the mounting part 131 is manufactured in a one-piece molding manner, that is, the connecting part 1311 and the first mounting part 1312 are integrally molded.

[0058] In some embodiments, the first mounting portion 1312 protrudes from the radial end face of the connecting portion 1311.

[0059] In this embodiment, as Figure 2The first mounting portion 1312 extends radially along the connecting portion 1311, thereby protruding from the radial end face of the connecting portion 1311, which can improve the connection strength of the first mounting portion 1312 (i.e., mounting member 131) to the constant lamp 2, thereby improving the connection strength between the ignition rod 1 and the constant lamp 2.

[0060] In some embodiments, the first mounting portion 1312 is circumferentially arranged around the axis of the connecting portion 1311.

[0061] In this embodiment, as Figure 2 The first mounting part 1312 surrounds the connecting part 1311, so that the force on the first mounting part 1312 is uniform, which can improve the stability of the first mounting part 1312 (i.e. the mounting part 131) connected to the constant lamp 2, thereby improving the connection stability between the ignition rod 1 and the constant lamp 2.

[0062] For example, the axis of the connecting part 1311 is parallel to or collinear with the axis of the ignition rod 1, such as... Figure 2 and Figure 3 The X-axis direction in the diagram. The radial direction of the connecting part 1311 is perpendicular to the axis of the connecting part 1311 (and the axis of the ignition rod 1), such as... Figure 2 and Figure 3 The Y-axis direction in the diagram.

[0063] Since the first mounting part 1312 protrudes from the radial end face of the connecting part 1311 and is arranged circumferentially around the axis of the connecting part 1311, the connection strength between the mounting part 131 and the continuous lamp 2 is increased, thereby improving the connection strength between the ignition rod 1 and the continuous lamp 2 and ensuring the stable operation of the torch system.

[0064] In some embodiments, the ignition rod 1 further includes a limiting member 14 and an elastic member 15 that cooperate with the mounting assembly 13.

[0065] In this embodiment, the limiting member 14 is engaged with the mounting component 13. The mounting component 13 is sleeved on the limiting member 14, thereby limiting the radial displacement of the limiting member 14 (or the ignition rod 1).

[0066] In some embodiments, in conjunction with reference Figure 4 As shown, the elastic member 15 has a first end 151 and a second end 152 that are opposite each other along the deformation direction.

[0067] In this embodiment, the spring is a compression type, which can be used to withstand axial compressive force and absorb energy through compression deformation, thereby playing the roles of vibration reduction and resetting. The deformation direction is the compression direction.

[0068] In some embodiments, the first end 151 abuts against the limiting member 14, and the second end 152 abuts against the conductive member 11, so that the conductive member 11 elastically abuts against the extension member 122.

[0069] In this embodiment, the mounting assembly 13 can restrict the limiting member 14 from moving away from the extension member 122 along the axial direction of the ignition rod 1. The limiting member 14 abuts against the elastic member 15 (i.e., the first end 151) on one side along the axial direction of the ignition rod 1, and abuts against the mounting assembly 13 on the opposite side along the axial direction of the ignition rod 1. At this time, when the elastic member 15 is compressed by the limiting member 14, the deformation force generated by the elastic member 15 will drive the conductive member 11 to abut against the extension member 122 along the axial direction of the ignition rod 1.

[0070] In this embodiment, the conductive element 11 elastically abuts against the extension element 122. This can be understood as the side of the guide element away from the extension element 122 being subjected to the rebound force (or deformation force) of the elastic element 15, making the conductive element 11 and the extension element 122 in close contact. Thus, the deformation force of the elastic element 15 provides a preload force to the conductive element 11 against the extension element 122, making it difficult for the conductive element 11 and the extension element 122 to lose contact, ensuring stable contact between the conductive element 11 and the extension element 122 to maintain current conduction.

[0071] In some embodiments, in conjunction with reference Figure 5 As shown, the conductive member 11 has a conductive portion 111 and a stop portion 112 protruding from the radial end face of the conductive portion 111.

[0072] In this embodiment, the stop portion 112 may be located at the end of the conductive portion 111, for example, at the end of the conductive portion 111 facing the extension member 122. Alternatively, the stop portion 112 may be located at other positions of the conductive portion 111, for example, the stop portion 112 may be disposed adjacent to the end of the conductive portion 111 facing the extension member 122.

[0073] For example, the stop portion 112 and the conductive portion 111 are connected by a socket weld, keeping them perpendicular to each other, and the welded end faces need to be smoothed.

[0074] In some embodiments, the elastic element 15 is sleeved on the conductive portion 111.

[0075] In this embodiment, since the elastic member 15 is sleeved on the conductive part 111, the elastic member 15 cannot detach from the conductive part 111 along the radial direction of the conductive part 111.

[0076] In some embodiments, the second end 152 abuts against the stop portion 112.

[0077] In this embodiment, after the elastic member 15 (i.e., the second end 152) abuts against the stop portion 112, the conductive member 11 is driven to elastically resist the extension member 122, thereby restricting the conductive member 11 from moving away from the extension member 122 along the axial direction of the ignition rod 1.

[0078] In this embodiment, as Figure 4The elastic element 15 is sleeved on the conductive part 111 and abuts against the stop part 112 along the axial direction of the ignition rod 1, which can also limit the bending or swinging of the conductive element 11.

[0079] In some embodiments, in conjunction with reference Figure 6 As shown, the outer diameter of the first end 151 is not less than the outer diameter of the second end 152.

[0080] In this embodiment, the elastic element 15 is a conical spring, such as a conical compression spring. Compared to a solution where the elastic element 15 is a cylindrical spring, the conical compression spring can better limit the radial offset or deflection of the conductive element 11 along the ignition rod 1.

[0081] In this embodiment, as Figure 4 The outer diameter of the first end 151 is relatively large, which increases the contact area between the elastic element 15 and the limiting element 14 and improves the abutment strength between the elastic element 15 and the limiting element 14. The outer diameter of the second end 152 is relatively small, which makes the elastic element 15 fit more closely to the conductive part 111, thereby clamping the conductive part 111 and limiting the conductive part 111 from radial displacement or deflection along the ignition rod 1.

[0082] For example, the height of the elastic element 15 is 8mm, with a total of 5.5 turns, and the support ring has 1 turn.

[0083] In some embodiments, the stop portion 112 and / or the conductive portion 111 abut against the extension member 122.

[0084] In this embodiment, the stop portion 112 is located at the end of the conductive portion 111 facing the extension member 122. At this time, both the stop portion 112 and the conductive portion 111 can abut against the extension member 122, which increases the contact area between the conductive portion 11 and the extension member 122 and avoids poor contact between the conductive portion 11 and the extension member 122 caused by the bending or swinging of the conductive portion 11 (i.e., the conductive portion 111).

[0085] In some other embodiments, the stop portion 112 and the conductive portion 111 are disposed adjacent to one end of the extension member 122, in which case the conductive portion 111 abuts against the extension member 122.

[0086] In some embodiments, the mounting component 13 includes a locking member 132 connected to the mounting member 131.

[0087] In this embodiment, the locking member 132 is detachably connected to the mounting member 131, for example, by a threaded connection. This facilitates the maintenance and replacement of the conductive member 11.

[0088] In some embodiments, in conjunction with reference Figure 7 As shown, the limiting member 14 includes a mounting tube 141 and a stop block 142 protruding from the radial end face of the mounting tube 141.

[0089] In this embodiment, the stop block 142 is circumferentially arranged relative to the axis of the limiting member 14. The stop block 142 is integrally formed with the mounting tube 141, which facilitates the manufacturing of the limiting member 14.

[0090] In some embodiments, the locking member 132 is fitted onto the mounting tube 141.

[0091] In this embodiment, as Figure 4 The locking element 132 is sleeved on the mounting tube 141 and can limit the radial displacement of the mounting tube 141 (i.e. the limiting element 14) along the ignition rod 1.

[0092] In some embodiments, the locking member 132 abuts against the side of the stop block 142 opposite to the elastic member 15.

[0093] In this embodiment, after the locking member 132 is fixed to the mounting member 131, the locking member 132 abuts against the side of the stop block 142 away from the elastic member 15, which can restrict the limiting member 14 from moving away from the extension member 122 along the axial direction of the ignition rod 1.

[0094] In this embodiment, one side of the limiting member 14 abuts against the elastic member 15, and the opposite side of the limiting member 14 abuts against the locking member 132, thereby limiting the axial displacement of the limiting member 14 along the ignition rod 1.

[0095] In some embodiments, the limiting member 14 includes a limiting tube 143 sleeved on the conductive member 11 and an mounting tube 141 sleeved on the limiting tube 143.

[0096] In this embodiment, combined with Figure 4 and Figure 7 The conductive element 11 passes through the limiting tube 143, which in turn passes through the mounting tube 141. The mounting tube 141 passes through the mounting assembly 13 (e.g., mounting cavity 133). This restricts the radial displacement of the conductive element 11 along the ignition rod 1.

[0097] In some embodiments, the limiting tube 143 is made of a conductive material.

[0098] In this embodiment, the limiting tube 143 is made of a conductive material, such as a metal. After the limiting tube 143 comes into contact with the conductive element 11, it can increase the conductive area of ​​the conductive element 11 and stably transmit the current to the extension element 122.

[0099] In this embodiment, the limiting tube 143 serves as an electrical connection bridge for the conductive component 11, and its good conductivity ensures that the energy loss of the current during transmission is minimized.

[0100] For example, both the limiting tube 143 and the conductive element 11 are made of stainless steel, and the conductivity of the conductive element 11 is better than that of the limiting tube 143.

[0101] In some embodiments, the mounting tube 141 is made of insulating material.

[0102] In this embodiment, the mounting tube 141 is made of insulating material to provide insulation protection for the outer side of the limiting tube 143 and the conductive component 11.

[0103] In some embodiments, a connecting adhesive layer 144 is filled between the limiting tube 143 and the mounting tube 141.

[0104] In this embodiment, the limiting tube 143 and the mounting tube 141 are fixed together by a connecting adhesive layer 144, so that the limiting tube 143 is not easy to shake in the mounting tube 141, thereby improving the stability of the conductive component 11 in the limiting tube 143.

[0105] In this embodiment, by filling the space between the limiting tube 143 and the mounting tube 141, the limiting tube 143 can be prevented from becoming loose in the mounting tube 141 after vibration, thus optimizing the conductive contact between the limiting tube 143 and the conductive component 11 and ensuring the stable operation of the limiting component 14.

[0106] For example, the adhesive layer 144 can be an inorganic adhesive, which can withstand temperatures up to 1300°C. The high temperature resistance and aging resistance of the inorganic adhesive can extend the service life of the limiting member 14.

[0107] In some embodiments, the extension member 122 includes a conductive terminal 1221 that abuts against the conductive member 11.

[0108] In this embodiment, the stop portion 112 and / or the conductive portion 111 abut against the conductive terminal 1221.

[0109] In some embodiments, the mounting assembly 13 has a mounting cavity 133, and the ignition rod 1 has a protective tube 16 located within the mounting cavity 133.

[0110] In this embodiment, the mounting cavity 133 is formed by the mounting member 131 and the locking member 132. The protective tube 16 is located inside the mounting cavity 133, which can reduce the influence of external environmental factors on the protective tube 16.

[0111] In some embodiments, the protective tube 16 is sleeved at the contact point between the conductive terminal 1221 and the conductive element 11.

[0112] In this embodiment, the protective tube 16 can protect the contact point between the conductive terminal 1221 and the conductive component 11.

[0113] In this embodiment, the protective tube 16 enables the conductive terminal 1221 to maintain stable contact with the conductive component 11, preventing interference from other components. The protective tube 16 provides support and stable connection between the conductive terminal 1221 and the conductive component 11, preventing them from tilting or deflecting.

[0114] In some embodiments, the protective tube 16 is made of insulating material.

[0115] In this embodiment, the protective tube 16 made of insulating material can play a role in current protection, such as preventing short circuits and electric shock risks.

[0116] In this embodiment, the conductive terminal 1221 and the conductive element 11 (e.g., the stop portion 112 and the conductive portion 111) are separated from the surrounding grounded portion or other conductive portion 111 by the protective tube 16, thus preventing current leakage. This achieves effective insulation against high voltage, avoids ignition energy loss, ensures successful ignition, and also prevents danger to operators.

[0117] In this embodiment, the protective tube 16 can also help maintain the electric field strength around the igniter 121, forming a sufficiently strong electric field between the igniter 121 and the ground electrode to ionize the gas near the electrode and generate an electric spark.

[0118] In this embodiment, the protective tube 16 can limit the distribution range of the electric field, concentrate the electric field in a specific area around the igniter 121, and enhance the electric field strength, which is beneficial to improving the efficiency of gas ionization.

[0119] For example, the insulation material used in the protective tube 16 is required to withstand a voltage of >20kV.

[0120] In some embodiments, in conjunction with reference Figure 8 As shown, the locking member 132 has a locking portion 1321 connected to the mounting member 131 and a rain cover portion 1322 connected to the locking portion 1321.

[0121] In this embodiment, the locking part 1321 is threadedly connected to the mounting part 131.

[0122] In some embodiments, in conjunction with reference Figure 3 As shown, the connecting part 1311 and the rain cover part 1322 are located on opposite sides of the first mounting part 1312.

[0123] In this embodiment, as Figure 3 After the ignition rod 1 is connected to the night light 2, the rain cover 1322 can waterproof the mounting components 13 (e.g., part of the limiting member 14) exposed to the outside of the night light 2, and prevent condensation.

[0124] In this embodiment, the rain cover 1322 prevents rainwater from directly entering the mounting cavity 133, avoiding rainwater seepage that could cause short circuits, electrode corrosion, or a decrease in insulation performance, thus ensuring the reliability of ignition.

[0125] In this embodiment, the rain cover 1322 can also reduce moisture condensation caused by temperature changes (such as diurnal temperature differences or temperature changes during torch operation). The rain cover 1322 can also reduce the impact of ambient humidity on the ignition rod 1, prevent moisture from condensing on internal components, and thus prevent corrosion and electrical failures caused by moisture.

[0126] In some embodiments, in conjunction with reference Figure 9 As shown, the extension member 122 includes a conductive core 1222 that electrically connects the conductive terminal 1221 to the ignition nozzle 121, and an extension tube 1223 that is sleeved on the outer periphery of the conductive core 1222.

[0127] In this embodiment, the extension member 122 includes an insulating layer 1224 located between the conductive core 1222 and the extension tube 1223. The insulating material used in the insulating layer 1224 is required to withstand a voltage of >20kV.

[0128] In some embodiments, at least a portion of the ignition nozzle 121 extends into the extension tube 1223 and is welded to the opening of the extension tube 1223.

[0129] In this embodiment, the extension member 122 includes a bushing 1225 located between the ignition nozzle 121 and the extension tube 1223. When the ignition nozzle 121 extends into the extension tube 1223, it is positioned using the bushing 1225. After the ignition nozzle 121 and the extension tube 1223 are aligned and positioned using the bushing 1225, they are fully welded at the opening along the circumferential direction of the extension tube 1223. The weld must meet the requirements for preventing rainwater infiltration and ensure the coaxiality between the extension tube 1223 and the ignition nozzle 121.

[0130] For example, the discharge element of the ignition nozzle 121 is made of ceramic semiconductor material and operates at a DC voltage of 2.2kV.

[0131] In some embodiments, the insulating material is alumina ceramic.

[0132] In this embodiment, the insulating material used for the protective tube 16 and the insulating layer 1224 can be 95% alumina ceramic.

[0133] For example, zirconia toughened alumina ceramics (ZTA) are also known as zirconia-toughened ceramics. Alumina ceramics are ceramic materials with alumina (Al2O3) as the main component. Alumina ceramics have good insulation, mechanical strength and high temperature resistance.

[0134] In some embodiments, the constant light 2 has a second mounting portion 22, and the first mounting portion 1312 and the second mounting portion 22 are configured as mutually mating flanges.

[0135] In this embodiment, the ignition rod 1 and the continuous lamp 2 are connected to each other using mutually cooperating flanges, which reduces the impact of vibration and ensures a more stable and reliable connection.

[0136] In this embodiment, the ignition rod 1 and the continuous lamp 2 are connected by a flange, which can withstand greater tension and pressure, ensuring a more stable connection and guaranteeing the stable operation of the flare system.

[0137] In this embodiment, the structure of the flange can evenly distribute the external force, making the force more uniform, avoiding component damage caused by stress concentration, and extending the service life of the ignition rod 1 and the night lamp 2.

[0138] In some embodiments, a gasket is installed at the sealing surface of the flange to effectively fill the small gaps between the flanges, providing good sealing and preventing gas leakage from causing danger. Compared to bolted connections, flange sealing can prevent some media in the environment (such as corrosive gases, liquids, or rainwater) from seeping through the thread gaps and corroding internal components, thus avoiding affecting the performance and lifespan of the ignition rod 1.

[0139] In some embodiments, the first mounting portion 1312 and the second mounting portion 22 are detachably connected.

[0140] In this embodiment, by opening corresponding mounting holes on the first mounting part 1312 and the second mounting part 22, for example, multiple mounting holes arranged circumferentially around the axis of the ignition rod 1, and by using multiple fasteners inserted into the corresponding mounting holes, detachable locking and fixing can be achieved.

[0141] In other embodiments, the first mounting portion 1312 and the second mounting portion 22 are welded together.

[0142] In this embodiment, the first mounting part 1312 and the second mounting part 22 are fixed by welding, that is, the flange is a welded flange.

[0143] In some embodiments, in conjunction with reference Figure 1 As shown, the continuous light 2 includes a fuel gas pipe 24 connected to the wind shield 21.

[0144] In this embodiment, fuel gas passes through fuel gas pipe 24, and simultaneously through control damper 25, ensuring that fuel gas and air are mixed in a certain proportion. After the fuel gas and air are mixed, they are ignited inside windproof cover 21 using igniter 121, completing the ignition operation of the continuous lamp 2.

[0145] In some embodiments, the second mounting portion 22 is connected to the fuel gas pipe 24.

[0146] In this embodiment, after the extension member 122 and the fuel gas pipe 24 are connected by a flange (i.e., connected by the first mounting part 1312 and the second mounting part 22), the axis of the extension member 122 and the axis of the fuel gas pipe 24 can be parallel or collinear. This ensures the docking accuracy between the extension member 122 and the fuel gas pipe 24, for example, meeting the coaxiality requirements between them.

[0147] In some embodiments, the extension 122 extends through the fuel gas pipe 24.

[0148] In this embodiment, the extension 122 is located inside the fuel gas pipe 24, which can reduce the space occupied by the flare system in the radial direction of the ignition rod 1, and is beneficial to the integration of the flare system.

[0149] In this embodiment, the connecting part 1311 is located inside the fuel gas pipe 24.
