Description

Technical Field

[0002] In industries such as petroleum and chemical industries, the flare system, as an important facility for safe production, can be used to incinerate and harmlessly discharge toxic and harmful waste gases discharged during normal production, accidents or emergencies. The pilot burner is an important part of the flare system and is used to timely ignite the waste gas discharged to the flare, thereby avoiding personal injury and environmental pollution caused by the waste gas. To ensure the safe and normal operation of the flare system, the pilot burner needs to burn constantly.

[0076] Hereinafter, specific embodiments of the present application will be described in more detail with reference to the accompanying drawings, which show representative embodiments of the present application and do not limit the present application.

[0077] For a closed - type ground flare, when the flare is operating, it is strictly prohibited for personnel to enter the windbreak wall. The operator can only view the operating status of the pilot burner and the burner through the observation holes on the windbreak wall outside the windbreak wall, but cannot enter the inner side of the windbreak wall to perform maintenance operations on the pilot burner. The maintenance content that the pilot burner usually needs to carry out includes: 1) adjustment or replacement of the ignition electrode, 2) adjustment of the air damper of the ejector, 3) replacement of the ignition high - voltage cable.

[0078] Aiming at the disadvantage that the pilot burner of the ground flare in the prior art cannot be maintained online during the operation of the flare, the present application provides a pilot burner assembly. As Figures 1 to 7 shown, the pilot burner assembly according to the present application includes a burner 100, a mixing gas pipe 110, an ejector 120, a guiding pipe 130, a sliding member 140 and a pushing - pulling member. The first end of the mixing gas pipe 110 is connected to the burner 100. The ejector 120 is connected to the second end of the mixing gas pipe 110. The first end of the guiding pipe 130 is connected to the burner 100. The guiding pipe 130 is used to accommodate the ignition device. The length direction of the guiding pipe 130 is consistent with the length direction of the mixing gas pipe 110. One end of the sliding member 140 can be connected to one or both of the mixing gas pipe 110 and the guiding pipe 130. The other end of the sliding member 140 is used to be connected to the guide rail 190 inside the windbreak wall 170 of the closed - type ground flare and is slidably and guidingly engaged with the guide rail 190 along the extending direction of the guide rail 190. The sliding and guiding engagement here can be understood as a cooperation relationship similar to that between a linear guide rail and a slider. One end of the pushing - pulling member is detachably connected to at least one of the mixing gas pipe 110, the ejector 120 and the guiding pipe 130. The other end of the pushing - pulling member is used to extend outside the windbreak wall 170 for applying a force along the extending direction of the guide rail 190 to the sliding member 140 during operation.

[0079] The pilot burner assembly can be constructed as a high - temperature - resistant stainless - steel structure to meet the use requirements of the high - temperature environment of the flare. The temperature resistance of the pilot burner assembly can be not less than 600 °C to meet the use requirements of the high - temperature environment of the ground flare, greatly increasing the reliability and service life of the pilot burner assembly. During use, a guide rail 190 is installed inside the windbreak wall 170, and the operator can push or pull the pilot burner assembly along the extending direction of the guide rail 190 outside the windbreak wall 170, so as to move the pilot burner assembly into or out of the windbreak wall 170, and then maintenance operations can be performed on the pilot burner assembly.

[0080] The pilot burner assembly can be understood to include a pilot burner body and mounting accessories. The pilot burner body can include a burner nozzle 100, a mixing gas pipe 110, a guiding pipe 130, and an ejector 120. The mounting accessories can include a pushing and pulling member.

[0081] According to the pilot burner assembly of the present application, by detachably connecting the pushing and pulling member to at least one of the mixing gas pipe 110, the ejector 120, and the guiding pipe 130, when the sliding member 140 is connected to the guide rail 190, by operating the pushing and pulling member to move along the guide rail 190, structures such as the ejector 120, the mixing gas pipe 110, the guiding pipe 130, and the burner nozzle 100 can be extended outside the windproof wall 170, so as to perform on-line maintenance on the pilot burner assembly. Since there is no need to enter the windproof wall 170, the safety is greatly improved.

[0082] By adopting the pilot burner assembly of the present application and cooperating with the guide rail 190 in the windproof wall 170 for use, even when the enclosed ground flare is in operation, the operator does not need to enter the high-temperature and high-risk area inside the windproof wall 170. By operating outside the windproof wall 170, the pilot burner assembly can be integrally moved along the extension direction of the guide rail 190 and passed through the installation hole 171 reserved on the windproof wall 170, so that the pilot burner assembly is partially or completely withdrawn outside the windproof wall 170, thereby enabling maintenance of the corresponding parts of the pilot burner assembly. After completing the maintenance operation of the pilot burner assembly, it is also operated outside the windproof wall 170. The pilot burner assembly is installed on the guide rail 190, and the pilot burner assembly is moved along the extension direction of the guide rail 190. Thus, by adopting the above solution, during the operation of the flare system, the disassembly, installation, and maintenance of the pilot burner assembly are very convenient; ensuring the safe and reliable operation of the pilot burner assembly greatly increases the reliability of the overall operation of the enclosed ground flare.

[0083] Refer to Figure 1 、 Figure 4 、 Figure 5 and Figure 7 In addition, the pilot burner assembly further includes an ignition extension rod 150. At least one ignition extension rod 150 can be provided. The ignition extension rod 150 is detachably connected to the second end of the guiding pipe 130. The ignition extension rod 150 connected to the guiding pipe 130 is used to connect the ignition device, that is, one of at least one ignition extension rod 150 is directly connected to the guiding pipe 130, and the ignition device is installed on the ignition extension rod 150 directly connected to the guiding pipe 130. Each of the at least one ignition extension rod 150 is connected in sequence. The at least one ignition extension rod 150 constitutes a pushing and pulling member. In other words, the combination of all the ignition extension rods 150 among the at least one ignition extension rod 150 constitutes a pushing and pulling member, which can be held by the operator to apply a force, so that the pilot burner body can move.

[0084] Continue to refer to Figure 1 、 Figure 4 、 Figure 5 and Figure 7 In the illustrated embodiment, two ignition extension rods 150 are provided, and the two ignition extension rods 150 are sequentially connected along the rod length direction of the ignition extension rods 150. An ignition device is installed on one of the ignition extension rods 150. After the ignition extension rods 150 and the ignition device are assembled, the combination of the ignition extension rods 150 and the ignition device is assembled into the guide tube 130 together, and the ignition device is assembled into the guide tube 130. The guide tube 130 positions and guides the ignition device. Among them, after the ignition device is installed on the ignition extension rod 150, the end of the ignition device away from the ignition extension rod 150 has an ignition electrode; after the ignition device is inserted into the guide tube 130, the ignition electrode of the ignition device is close to the burner 100, so as to ignite the mixed gas output at the burner 100.

[0085] Refer to Figures 1 to 3 、 Figure 5 and Figure 7 For example, the inside of the ejector 120 has a mixing gas chamber 122. The mixing gas chamber 122 is used to mix fuel gas and air. The outside of the ejector 120 is provided with an air inlet 121a, an air inlet 121b and an air outlet 121c that communicate with the mixing gas chamber 122. The air inlet 121a and the air outlet 121c are respectively located at both ends of the ejector 120 in the length direction. The length direction of the ejector 120 is parallel to the length direction of the mixing gas pipe 110. The air outlet 121c is connected to the second end of the mixing gas pipe 110 and is used to output the mixed gas of air and fuel gas to the mixing gas pipe 110. The mixed gas is transported to the burner 100 through the guidance of the mixing gas pipe 110. The air inlet 121b is located on the side of the ejector 120. A damper that can move along the length direction of the ejector 120 is provided at the air inlet 121b. The moving damper is used to adjust the area covered by the air inlet 121b. That is, by moving the damper along the length direction of the ejector 120, the cross-sectional area of the air inlet 121b for air circulation can be adjusted, so as to adjust the air inlet speed, and further the size of the flame can be adjusted.

[0086] Continue to refer to Figures 1 to 3 、 Figure 5 and Figure 7In addition, the ever-burning lamp assembly further includes an air intake pipe 160. At least one air intake pipe 160 is provided. The air intake pipe 160 is detachably connected to the air inlet 121a. Moreover, each air intake pipe 160 is located on the side of the ejector 120 away from the mixed gas pipe 110 along the length direction of the ejector 120, and is sequentially arranged along the length direction of the ejector 120. For example, two air intake pipes 160 are provided, one of the two air intake pipes 160 is directly detachably connected to the air inlet 121a, and two adjacent air intake pipes 160 are detachably connected. At least one air intake pipe 160 constitutes a push-pull member, that is, the combination of all the air intake pipes 160 in at least one air intake pipe 160 connected in sequence can be used as a push-pull member. After each air intake pipe 160 is sequentially connected and connected to the air inlet 121a of the ejector 120, the air intake pipe 160 farthest from the ejector 120 is used to connect the fuel gas pipe. In the illustrated embodiment, two intake pipes 160 are provided.

[0087] Continue reading Figures 1 to 3 , Figure 5 and Figure 7 In order to facilitate the adjustment of the position of the damper, the damper may have an operating portion 125 for adjustment operation. The ever-burning lamp assembly may also include an adjustment rod 126. At least one adjustment rod 126 is provided. The adjustment rod 126 is detachably connected to the operating portion 125. At least one adjustment rod 126 is sequentially arranged along the rod length direction of the adjustment rod 126, that is, at least one adjustment rod 126 is sequentially connected along the rod length direction of the adjustment rod 126.

[0088] See also Figure 2 The damper operating part 125 may be a rod structure. The length direction of the rod structure may be consistent with the length direction of the ejector 120.

[0089] See also Figure 2 and Figure 3 For another example, the ejector 120 may include a shell 121. The outer contour of the shell 121 is cylindrical. A mixed air chamber 122 is formed inside the shell 121. An air inlet 121a, an air inlet 121b and an air outlet 121c are provided on the outer surface of the shell 121. The damper may be configured as a sleeve 124. The sleeve 124 is movably sleeved on the outside of the shell 121 along the axial direction of the shell 121. The axial direction of the shell 121 is parallel to the axial direction of the sleeve 124. In the present application, the sleeve 124 may be slidably connected to the shell 121 along the axial direction of the shell 121. The air intake volume of the air inlet 121b may be adjusted by pushing and pulling the adjusting rod 126. The shell 121 may be configured as a Venturi tube, and the air is automatically introduced from the air inlet 121b by utilizing the Venturi effect.

[0090] In some other embodiments of the present application, the sleeve 124 can also be threadedly connected to the housing 121. When the sleeve 124 rotates relative to the housing 121, the sleeve 124 moves along the axial direction of the housing 121, thereby adjusting the air intake of the air inlet 121b. Since the sleeve 124 and the housing 121 are connected by threaded connection, on the one hand, the position of the sleeve 124 along the axial direction of the housing 121 can be limited when there is no need to adjust the position of the sleeve 124, and on the other hand, when the position of the sleeve 124 needs to be adjusted, the position of the sleeve 124 can be adjusted by rotating the sleeve 124, which is simpler and more reliable.

[0091] Furthermore, in the embodiment in which the sleeve 124 and the housing 121 are threadedly connected, the adjusting rods 126 connected in series in sequence can also constitute the above-mentioned push-pull component. For example, two adjusting rods 126 are provided, one of the two adjusting rods 126 is used to be directly connected to the operating part 125, and the two adjusting rods 126 are connected in sequence along the rod length direction of the adjusting rod 126. After the two adjusting rods 126 are connected to the operating part 125, the adjusting rods 126 can be used as a push-pull component. As long as the adjusting rod 126 farthest from the operating part 125 can conveniently move the ever-burning lamp body from the high-temperature area inside the windbreak wall 170 to the non-high-temperature area outside the windbreak wall 170, and can move the ever-burning lamp body from the non-high-temperature area outside the windbreak wall 170 to the high-temperature area inside the windbreak wall 170, it will be sufficient.

[0092] Continue reading Figure 2 and Figure 3 Furthermore, the air inlets 121b may be arranged at intervals along the circumference of the shell 121, so that air can enter the mixing chamber 122 from the circumferential side of the shell 121 at the same time, thereby improving the air intake efficiency and also facilitating the full mixing of air and fuel gas.

[0093] See also Figure 1 , Figure 5 and Figure 7, in the illustrated embodiment, the sliding member 140 can be connected to the middle of the mixing gas pipe 110. Compared with setting the sliding member 140 at one end of the mixing gas pipe 110 closer to the burner 100, setting the sliding member 140 in the middle of the mixing gas pipe 110 can prevent the burner 100 from being too close to the guide rail 190 after the pilot burner body moves into place on the guide rail 190, thereby preventing the flame of the burner 100 from being affected by the guide rail 190; at the same time, it also helps to reduce the length dimension of the guide rail 190. Compared with setting the sliding member 140 at one end of the mixing gas pipe 110 closer to the ejector 120, it is more conducive to maintaining the balance of the weight of the pilot burner body on both sides of the sliding member 140. If the sliding member 140 is set at one end of the mixing gas pipe 110 closer to the ejector 120, the center of gravity of the pilot burner body may be closer to the burner 100. Then, when installing the pilot burner body on the guide rail 190, the operator needs to hold the end of the pilot burner body far from the center of gravity for the assembly operation, which will be relatively more laborious and make the operation not so flexible and convenient.

[0094] Refer to Figure 3 , in addition, the ejector 120 can further include a gas nozzle 123. The gas nozzle 123 is arranged inside the mixing gas chamber 122. The inlet of the gas nozzle 123 is connected to the air inlet 121a. The outlet of the gas nozzle 123 faces the air outlet 121c. The reason for setting the gas nozzle 123 is that it can make the fuel gas enter the mixing gas pipe 110 more reliably, and then helps to prevent the fuel gas from leaking from the air inlet 121b. For example, the outlet of the gas nozzle 123 can be closer to the burner 100 than the air inlet 121b.

[0095] Refer to Figure 5 and Figure 7 , in the pilot burner assembly of the present application, the connection manner between the adjusting rod 126 and the operating part 125 and the connection manner between adjacent adjusting rods 126 can be a threaded connection manner. The connection manner between the inlet pipe 160 and the ejector 120 and the connection manner between adjacent inlet pipes 160 can use a threaded connection manner or a flange connection manner. The connection manner between the ignition extension rod 150 and the guide pipe 130 and the connection manner between adjacent ignition extension rods 150 can be a threaded connection manner.

[0096] Refer to Figures 1 to 7, the present application also provides an enclosed ground flare, which may include a windbreak wall 170, a flare stack 180, a burner (not shown), a guide rail 190, and the pilot lamp assembly according to the above. An installation hole 171 is formed in the side of the windbreak wall 170. The installation hole 171 communicates with the inner and outer sides of the windbreak wall 170 respectively. The flare stack 180 is located inside the windbreak wall 170. The flare stack 180 may be arranged concentrically with the windbreak wall 170, and a burner is arranged in the middle of the circular area enclosed by the flare stack 180. The guide rail 190 is arranged inside the windbreak wall 170 and is located below the flare stack 180. One end of the guide rail 190 is correspondingly arranged with the installation hole 171 and can be connected to the windbreak wall 170. The other end of the guide rail 190 can be connected to the lower part of the flare stack 180. The sliding member 140 of the pilot lamp assembly is movably connected to the guide rail 190 along the extending direction of the guide rail 190. When the pilot lamp assembly is connected to the guide rail 190, the burner 100 of the pilot lamp assembly is closer to the burner, so as to ignite the combustible waste gas discharged from the burner in time when the burner 100 is in a constantly burning state. When the pilot lamp assembly moves along the extending direction of the guide rail 190 through the sliding member 140, the pilot lamp assembly is allowed to move into and out of the installation hole 171 of the windbreak wall 170 along the extending direction of the guide rail 190.

[0097] For the enclosed ground flare according to the present application, by arranging the guide rail 190 between the flare stack 180 inside the windbreak wall 170 and the inner wall of the windbreak wall 170, and connecting the pilot lamp assembly to the guide rail 190 through the sliding member 140, the pilot lamp body can be moved into and out of the installation hole 171 of the windbreak wall 170 by operating the push-pull member of the pilot lamp assembly, thereby facilitating the maintenance operation of the pilot lamp assembly.

[0098] Refer to Figures 5 to 7, for example, the guide rail 190 may include a first guide rail segment 191. The first guide rail segment 191 is inclined with respect to the height direction of the windbreak wall 170. The first guide rail segment 191 has a first end and a second end spaced apart along the extension direction of the guide rail 190. The first end of the first guide rail segment 191 is higher than the second end of the first guide rail segment 191, and the second end of the first guide rail segment 191 is closer to the mounting hole 171 than the first end of the first guide rail segment 191. When an operator operates at the mounting hole 171 outside the windbreak wall 170, by pulling any one of the ignition extension rod 150, the adjustment rod 126, and the air inlet pipe 160 of the pilot lamp assembly, the pilot lamp body can be moved from the first end of the first guide rail segment 191 to the second end of the first guide rail segment 191, so that part or all of the pilot lamp body is moved outside the windbreak wall 170. Similarly, by pushing any one of the ignition extension rod 150, the adjustment rod 126, and the air inlet pipe 160 of the pilot lamp assembly, the pilot lamp body can be moved from the second end of the first guide rail segment 191 to the first end of the first guide rail segment 191 until the sliding member 140 moves to the first end of the pilot lamp body.

[0099] Continue to refer to Figures 5 to 7 , further, the guide rail 190 may further include a second guide rail segment 192. The first end of the second guide rail segment 192 is connected to the first end of the first guide rail segment 191. The second end of the second guide rail segment 192 is farther from the first guide rail segment 191 than the first end of the second guide rail segment 192, and the second end of the second guide rail segment 192 is not higher than the first end of the second guide rail segment 192. By providing the second guide rail segment 192, and the end of the second guide rail segment 192 far from the first guide rail segment 191 is not higher than the first end of the second guide rail segment 192, after the sliding member 140 moves from the first guide rail segment 191 to the second guide rail segment 192, it is ensured that the sliding member 140 can stay reliably on the second guide rail segment 192 without causing the entire pilot lamp assembly to slide down along the extension direction of the first guide rail segment 191 due to the self-weight of the pilot lamp assembly. That is, the second guide rail segment 192 helps the pilot lamp assembly to be supported reliably and stably, so that the pilot lamp assembly can stay on the second guide rail segment 192.

[0100] Refer to Figure 7 , for example, the second guide rail segment 192 may be perpendicular to the height direction of the windbreak wall 170. That is, the extension direction of the second guide rail segment 192 may be horizontal, so as to facilitate positioning the height of the burner 100 of the pilot lamp assembly located on the second guide rail segment 192, so that the position of the burner 100 when staying on the second guide rail segment 192 can be accurately aligned with the burner.

[0101] Refer to Figures 5 to 7, during the process in which the sliding member 140 moves from the first guide rail section 191 to the second guide rail section 192, in order to prevent the sliding member 140 from slipping off the end of the second guide rail section 192, the guide rail 190 may further include a limiting member 193. The limiting member 193 is provided at the second end of the second guide rail section 192, that is, the limiting member 193 is located at one end of the second guide rail section 192 that is far from the first guide rail section 191. And, the limiting member 193 is correspondingly arranged with the sliding member 140 connected to the guide rail 190. The limiting member 193 is used to limit the sliding member 140 from detaching from the second end of the second guide rail section 192.

[0102] Continue to refer to Figures 5 to 7 , in the illustrated embodiment, the limiting member 193 is configured as a limit pin. By the limit pin abutting against and blocking the sliding member 140 located in the second guide rail section 192 from continuing to move in the direction away from the first guide rail section 191.

[0103] Refer to Figure 6 , exemplarily, the flare stack 180 may be connected to the upper part of the first guide rail section 191. And the distance between the flare stack 180 and the first end of the first guide rail section 191 is greater than the distance between the flare stack 180 and the second end of the first guide rail section 191.

[0104] Refer to Figure 1 and Figure 4 , in the illustrated embodiment, the above-mentioned sliding member 140 includes a suspension rod 142 and a hook 141. One end of the suspension rod 142 is connected to the mixing gas pipe 110. The other end of the suspension rod 142 is connected to the hook 141 for hanging on the guide rail 190. The specific structure of the hook 141 here is set according to the structure of the guide rail 190.

[0105] Refer to Figures 5 to 7, for example, the guide rail 190 is configured as an H-shaped steel, which has a first plate body parallel to each other and a second plate body connected between the two first plate bodies. When manufacturing the H-shaped steel into the guide rail 190, one end of a certain length of the H-shaped steel is bent, and the bending axis is perpendicular to the second plate body and parallel to the first plate body, and the included angle formed at the bending part is an obtuse angle. The included angle formed at the bending part is the included angle between the above-mentioned first guide rail section 191 and the second guide rail section 192. When installing the guide rail 190, the included angle at the bending part is arranged downward. Correspondingly, the hook 141 can be configured as a U-shaped part 141a and a hanging part 141b extending from both ends of the U-shaped part 141a towards each other. The two hanging parts 141b are arranged at intervals, and the interval between the two hanging parts 141b is used to accommodate the second plate body. The two hanging parts 141b are used to overlap on the upper surface of the lower one of the two first plate bodies. The opening space of the U-shaped part 141a is used to accommodate the lower one of the two first plate bodies. In short, the illustrated hook 141 provides a T-shaped accommodation opening through which the inverted T-shaped structure on the guide rail 190 can move. The T-shaped structure here is the structure composed of the second plate body and the lower one of the two first plate bodies. Those skilled in the art can understand that as a deformation of the guide rail 190, the guide rail 190 can also be configured as a steel structure with a T-shaped cross-section.

[0106] Continue to refer to Figures 5 to 7 , the guide rail 190 is made of I-shaped steel of high-temperature resistant stainless steel, and other materials can also be used. One end of the I-shaped steel is welded and fixed to the cylinder body of the torch cylinder 180, and the other end is fixed to the inner wall of the windbreak wall 170. After the I-shaped steel is installed in place, one end is high and the other end is low. A small flat area is bent at the higher end of the I-shaped steel to eliminate the downward sliding force of the pilot burner assembly along the guide rail 190 after it is installed in place. A limit pin is provided at the higher end of the guide rail 190 to prevent the pilot burner assembly from falling off from the end of the guide rail 190 during installation.

[0107] Refer to Figures 1 to 7, the pilot lamp assembly with rail-mounted installation can be made of high-temperature stainless steel. The burner 100 can be the burner 100 with a protective cover as shown in the figure. The windproof cover is beneficial to stabilizing the flame and preventing the flame from being extinguished due to wind blowing. The air inlet 121a of the ejector 120 can be connected to the fuel gas pipe outside the windbreak wall 170 through a plurality of inlet pipes 160. The operation part 125 on the sleeve 124 can be connected to a plurality of adjusting rods 126 and extend outside the windbreak wall 170, so that the adjustment of the air damper can be carried out outside the windbreak wall 170. The guide pipe 130 can be welded to one or both of the mixing gas pipe 110 and the windproof cover of the burner 100. Before the ignition device is inserted into the guide pipe 130, the ignition device can be cascade-connected to the ignition extension rod 150. The ignition device can be implemented with the structure of the patent number CN216667746 U. One end of the guide pipe 130 is close to the burner 100, and the other end can be connected in series with the ignition extension rod 150 until the end of the ignition extension rod 150 farthest from the guide pipe 130 can extend outside the windbreak wall 170. The ignition extension rod 150 extending outside the windbreak wall 170 is connected to the ignition cable located outside the windbreak wall 170. The sliding member 140 is welded to the mixing gas pipe 110 and can be hung on the rail 190. After the pilot lamp assembly is hung on the rail 190 through the sliding member 140, the pilot lamp assembly can be conveniently moved along the rail 190, which is beneficial to the quick disassembly and installation of the pilot lamp assembly. The size of the installation hole 171 on the windbreak wall 170 can be adapted to the outer contour size of the pilot lamp assembly so that the pilot lamp assembly can pass through.

[0108] Refer to Figure 5 and Figure 7 , in addition, the enclosed ground flare can further include an ignition cable (not shown) and a fuel gas pipe (not shown). The ignition cable is connected to the ignition extension rod 150 far from the guide pipe 130. One end of the fuel gas pipe is detachably connected to the inlet pipe 160 far from the ejector 120. The other end of the fuel gas pipe is used to connect to the gas source. The ignition cable and the fuel gas pipe can be constructed in the common structures in the prior art.

[0109] Refer to Figure 7, in the figure, the adjusting rod 126, the ignition extension rod 150, and the intake pipe 160 are each set to two. The disassembly process of the pilot lamp assembly is as follows: In the (a) state, the pilot lamp assembly is in the installed position on the guide rail 190. At this time, the ignition cable can be removed from the ignition extension rod 150 first. In the (b) state, the outermost adjusting rod 126, the intake pipe 160, and the ignition extension rod 150 of the pilot lamp assembly are completely moved out beyond the windbreak wall 170, and the outermost adjusting rod 126, the intake pipe 160, and the ignition extension rod 150 are removed. In the (c) state, the pilot lamp is further pulled out along the extension direction of the guide rail 190 so that the remaining adjusting rod 126, the intake pipe 160, and the ignition extension rod 150 are completely moved out beyond the windbreak wall 170, and the remaining adjusting rod 126, the intake pipe 160, and the ignition extension rod 150 are removed. In the (d) state, the pilot lamp body can be further pulled out so that the pilot lamp body is in a position where it can be maintained. If necessary, the pilot lamp body can be completely pulled out to the outside of the windbreak wall 170.

[0110] Continue to refer to Figure 7 , when the pilot lamp assembly needs to be disassembled for maintenance, the operator can operate outside the windbreak wall 170. First step, disconnect the connection between the pilot lamp assembly and the fuel gas pipe outside the windbreak wall 170, pull the pilot lamp assembly out appropriately as a whole, remove the first ignition extension rod 150, the first adjusting rod 126, and the first section of the intake pipe 160, and then pull the remaining part of the pilot lamp assembly out along the guide rail 190 as a whole until the second ignition extension rod 150, the adjusting rod 126, and the intake pipe 160 are completely outside the windbreak wall 170. Second step, remove the second adjusting rod 126, the ignition extension rod 150, and the intake pipe 160, and then the remaining part of the pilot lamp assembly can be pulled out along the guide rail 190 again as a whole until the part to be maintained is outside the windbreak wall 170, and then the maintenance operation on the pilot lamp body can be carried out safely.

[0111] Refer to again Figure 7 , after the maintenance of the pilot lamp body is completed, it can be installed in place in the reverse order of the above disassembly steps. For example, it can be: First step, first connect the second adjusting rod 126, the ignition extension rod 150, and the intake pipe 160 to the pilot lamp body, and push the pilot lamp body up along the guide rail 190 to a suitable position. Second step, connect the first adjusting rod 126, the ignition extension rod 150, and the intake pipe 160 to the second adjusting rod 126, the ignition extension rod 150, and the intake pipe 160 installed previously respectively to form the pilot lamp assembly, and push the pilot lamp assembly up to the in-place position again. Finally, connect the pilot lamp assembly to the fuel gas pipe outside the windbreak wall 170 so that the pilot lamp assembly is restored to the installed position, and at this time the enclosed ground flare can resume normal operation.

[0112] As described above, the enclosed ground flare of the present application adopts a pilot burner assembly installed by a guide rail, which solves the problem that the pilot burner cannot be maintained during the operation of the enclosed ground flare, and can greatly improve the reliability and operation stability of the enclosed ground flare. The pilot burner assembly installed by a guide rail of the present application is applicable to ground flares with various installation heights.

[0113] In some other embodiments of the present application, the guide rail 190 can be implemented as a part of the above-mentioned pilot burner assembly. That is, the guide rail 190 is an installation accessory for the pilot burner body, and the pilot burner body and other structures together form a pilot burner assembly. Thus, the pilot burner assembly including the guide rail 190 can be used as a complete set of devices and popularized and applied to different flares. For example, it can be applied to other types of ground flares or can be applied to elevated flares.
