The furnace structure can include a furnace body and heating tubes (which can be quartz tubes). The furnace body includes an outer shell, an insulation layer, and heating elements. The insulation layer can be located inside the outer shell, and the heating elements are generally located between the insulation layer and the heating tubes. The sheet materials can be coated inside the heating tubes.

[0003] Currently, in horizontally placed tubular furnace structures, multiple temperature zones are arranged along the axis of the heating tubes.

The insulation layer inside the outer shell is typically a single, integral piece, and is fixedly connected to the heating element (e.g., heating wire). When a heating element fails, the entire furnace structure needs to be replaced, resulting in long replacement cycles and high replacement costs. Utility Model Content

[0023] 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 the embodiments.

[0024] The term "multiple" in this application refers to two or more. Furthermore, it should be understood that the terms "first," "second," etc., used in the description of this application are used only for descriptive purposes and should not be construed as indicating or implying relative importance, nor as indicating or implying order.

[0025] In the description of the embodiments in this application, the words "exemplary" or "for example" are used to indicate that they are examples, illustrations, or descriptions. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design options. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0026] Please see Figure 1 and Figure 2 , Figure 1 and Figure 2 An embodiment of this application provides a furnace body structure 100. The furnace body structure 100 can be applied to a reaction furnace (not shown).

[0027] In embodiments of this application, the reactor may be a horizontally arranged furnace. The reactor may include a furnace body structure 100 and heating tubes (not shown). The heating tubes are housed within the furnace body structure 100. The heating tubes may house multiple sheet materials, allowing the furnace body structure 100 to house multiple sheet materials. Reaction gases may be introduced into the heating tubes, and the furnace body structure 100 may heat the heating tubes, thereby heating the multiple sheet materials and enabling the sheet materials within the heating tubes to undergo coating processing.

[0028] In the embodiments of this application, the type of sheet material is not specifically limited. For example, the sheet material may be, but is not limited to, silicon wafers, silicon carbide wafers, or wafers.

[0029] In the embodiments of this application, the principle of coating sheet materials by the reactor is not specifically limited. For example, the reactor can perform chemical vapor deposition (CVD) or diffusion processes to achieve coating of sheet materials.

[0030] In the embodiments of this application, the length direction of the reactor can be located on a horizontal plane, so that the reactor can be maintained in a horizontal position. The length direction of the furnace body structure 100 coincides with the length direction of the reactor.

[0031] In one embodiment, the furnace structure 100 may include an outer shell 10, a heating mechanism 20, and electrode plates 30.

[0032] The outer casing 10 may include a first casing 11 and a second casing 12, wherein there is one second casing 12 and multiple first casings 11. The multiple first casings 11 can be arranged along the length of the furnace structure 100, and each of the multiple first casings 11 is detachably connected to the second casing 12. The second casing 12 has a semi-circular cross-section, and each first casing 11 also has a semi-circular cross-section, with the length of each first casing 11 being less than the length of the second casing 12. Each first casing 11 has a mounting opening 111 that communicates with the space inside the outer casing 10.

[0033] Please refer to the following: Figure 3 The number of heating field mechanisms 20 can be multiple. Each heating field mechanism 20 can correspond one-to-one with a number of first housings 11. The first housings 11 and second housings 12 can enclose the outer sides of the multiple heating field mechanisms 20. Each heating field mechanism 20 is arranged adjacent to its corresponding first housing 11. Each first housing 11 can cover the corresponding heating field mechanism 20 in a direction perpendicular to the length of the furnace structure 100. Each heating field mechanism 20 can include an insulation layer 21, a heating element, and a connecting wire 22. The first housings 11 and second housings 12 enclose the outer sides of the multiple insulation layers 21. The cross-section of the insulation layer 21 can be annular. The insulation layer 21 is connected to the heating element, which can be fixedly installed inside or outside the insulation layer 21. The connecting wire 22 can be electrically connected to the heating element, and can pass through the insulation layer 21 and extend out of the outer shell 10 through a corresponding mounting port 111.

[0034] Each connecting wire 22 is provided with a corresponding electrode plate 30. The part of each connecting wire 22 that extends out of the outer casing 10 is welded and fixed to the corresponding electrode plate 30 and electrically connected to the electrode plate 30. The electrode plate 30 can establish an electrical connection with an external power source and obtain current from the external power source; the electrode plate 30 can transmit current to the corresponding connecting wire 22, so that the corresponding heating element is energized and operates.

[0035] In the embodiments of this application, the connection method for detachable connection is not specifically limited. For example, the detachable connection method may include, but is not limited to, bolt connection, screw connection, and snap-fit ​​connection.

[0036] It is understood that in each thermal field mechanism 20, the insulation layer 21 can surround and form a subspace 211, and the subspace 211 surrounded by multiple thermal field mechanisms 20 can form a receiving space (not shown in the figure). The heating tube can be completely received within the receiving space; the sheet material inside the heating tube can be arranged along the length of the reactor, so that the thermal field generated by each thermal field mechanism 20 can correspond to a portion of the sheet material inside the heating tube.

[0037] The electrode sheet 30 is made of conductive metal. The connecting wire 22 is also made of conductive metal and may be covered with insulating material. When current is applied to the electrode sheet 30 and transmitted to the connecting wire 22, the current can be transmitted to the heating element. The heating element, when energized, generates heat to heat the subspace 211 formed by the thermal field mechanism 20. When multiple heating elements are energized and generate heat, the heating tube within the receiving space and the sheet material located within the heating tube can be heated so that the temperature of the sheet material reaches the temperature required for coating processing. The heating element can be a component that achieves heating through the principle of electrothermal generation. In the embodiments of this application, the type of heating element is not specifically limited. For example, the heating element can be, but is not limited to, an electric heating wire.

[0038] Simultaneously, multiple heating elements 20 can operate independently, meaning that energizing or de-energizing each heating element 20 does not affect the energizing or de-energizing of other heating elements 20, allowing each heating element 20 to heat the sub-space 211 it surrounds. In this way, multiple heating elements arranged along the length of the furnace structure 100 can be formed within the furnace structure 100, each capable of heating its corresponding sheet material. Operators can test the heat generated by each heating element 20 under different currents and, according to the requirements of the coating process, apply different or the same current to each heating element 20, thereby adjusting the temperature of the sheet material within each heating element to the temperature required for the coating process.

[0039] The outer casing 10 has an open end along its length. The insulation layer 21 in the furnace structure 100, furthest from the opening of the outer casing 10, can be closed on the side furthest from the opening. The heating tube can enter the receiving space from the open end of the outer casing 10. An end cap (not shown) is detachably connected to the open end of the outer casing 10; the end cap can close the opening of the outer casing 10, thus sealing the furnace structure 100. The heating tube has an open end; when the heating tube is located within the receiving space, the opening is at the end facing the end cap, and the end cap can simultaneously close the opening, thus sealing the heating tube.

[0040] In the embodiments of this application, the material of the heating element is not specifically limited. For example, the heating element can be, but is not limited to, quartz.

[0041] In other embodiments, the heating element can cooperate with the heating tube to heat the sheet material located in the heating tube through the principles of electromagnetism and magnetism.

[0042] It is understood that the insulation layer 21 can block heat when the heating element heats the containment space, thereby reducing the loss of heat to the outside of the outer shell 10, which can improve the efficiency of the furnace structure 100 in heating sheet materials and improve the efficiency of sheet material coating processing.

[0043] In the embodiments of this application, the material of the insulation layer 21 is not specifically limited. For example, the material of the insulation layer 21 may be, but is not limited to, aluminum silicate.

[0044] It is understandable that as the furnace structure 100 operates for longer periods, some heating elements may age or become damaged. When a heating element ages or becomes damaged, the operator first removes the heating tube from the furnace structure 100. Then, the corresponding first shell 11 can be disassembled from the second shell 12, and the corresponding thermal field mechanism 20 can be removed from the notch formed on the outer shell 10 after the first shell 11 is disassembled. The operator can then repair the heating element within the thermal field mechanism 20; alternatively, the operator can install a new thermal field mechanism 20 inside the outer shell 10 through the notch on the outer shell 10, and then reinstall the first shell 11 onto the second shell 12. In this way, when a heating element needs to be replaced or repaired, the operator can remove the corresponding thermal field mechanism 20 separately without disassembling other thermal field mechanisms 20, which improves the convenience of disassembling and replacing the thermal field mechanism 20. At the same time, it avoids replacing the entire insulation layer 21 when a heating element needs to be replaced, thus reducing the maintenance cost of the furnace structure 100.

[0045] Before the heating mechanism 20 is installed inside the outer casing 10, the connecting wire 22 can be pre-welded and fixed to the corresponding electrode plate 30, establishing an electrical connection. Then, when the heating mechanism 20 is installed inside the second casing 12, and the first casing 11 is installed on the second casing 12, the connecting wire 22 and the electrode plate 30 can be connected to the second casing 12 through the corresponding mounting port 111 on the first casing 11 without interference from the quick-release mechanism 40. The electrode plate 30 can be installed simultaneously with the heating mechanism 20, thus improving the ease of installation of the heating mechanism 20 at the location of the furnace structure 100, reducing the on-site welding process of the connecting wire 22 and the electrode plate 30, and improving the installation efficiency of the heating mechanism 20.

[0046] Please refer to the following: Figure 4In some embodiments, the furnace body structure 100 may further include multiple quick-release mechanisms 40. Each thermal field mechanism 20 corresponds to at least one quick-release mechanism 40. Each quick-release mechanism 40 may include a positioning component 41. The positioning component 41 is detachably connected to the insulation layer 21 in the corresponding thermal field mechanism 20 and is located outside the insulation layer 21. The positioning component 41 may be located at the corresponding mounting opening 111 and extend out of the mounting opening 111. A positioning groove 411 may be formed on the positioning component 41, through which the connecting wire 22 passing through the insulation layer 21 can pass.

[0047] Each positioning groove 411 may include two sub-grooves. Each positioning assembly 41 may include two positioning elements 412, which are symmetrically arranged along the length of the furnace body structure 100 and are detachably connected to the outer side of the corresponding insulation layer 21. Each positioning element 412 has a sub-groove on the side facing the other positioning assembly. When the two positioning elements 412 are attached to each other, the two sub-grooves can cooperate to form a positioning groove 411. Each electrode plate 30 can be received on the corresponding positioning element 412 and is detachably connected to the corresponding positioning element 412. Each electrode plate 30 is welded and fixed to the part of the corresponding connecting line 22 extending from the positioning groove 411.

[0048] For example, the electrode plate 30 can be detachably connected to the corresponding positioning member 412 via the first mounting member 42. The first mounting member 42 can be a bolt, and the screw portion of the first mounting member 42 can pass through the electrode plate 30 and the corresponding positioning member 412. The nut portion of the first mounting member 42 can be tightened onto the screw portion and abut against the electrode plate 30 or the positioning member 412 to achieve relative fixation between the electrode plate 30 and the positioning member 412. The direction in which the screw portion of the first mounting member 42 passes through the electrode plate 30 and the positioning member 412 can be perpendicular to the length direction of the furnace structure 100.

[0049] It is understood that after the thermal field mechanism 20 is installed inside the outer shell 10 and the corresponding first shell 11 is installed on the second shell 12, the operator can move the two separate positioning pieces 412 to the positions of the corresponding mounting ports 111, so that the two positioning pieces 412 are close to each other in the length direction of the furnace structure 100, and the connecting line 22 extending from the insulation layer 21 enters the corresponding sub-slot. When the two positioning pieces 412 are in contact with each other, the corresponding connecting line 22 can be located in the positioning groove 411 formed by the sub-slots of the two positioning pieces 412; at the same time, the positioning piece 412 can receive the corresponding electrode sheet 30.

[0050] The positioning groove 411 of each positioning component 41 can limit the swing of the corresponding connecting line 22, and the positioning component 41's support of the electrode sheet 30 can limit the movement of the electrode sheet 30 and the swing of the connecting line 22 connected to the electrode sheet 30, reducing the probability that the electrode sheet 30 and the connecting line 22 will be misaligned with other components due to swing, thereby reducing the probability of short circuit between the electrode sheet 30 and the thermal field mechanism 20; at the same time, it can reduce the probability of the electrode sheet 30 separating from the connecting line 22, reduce the probability of the thermal field mechanism 20 losing power during the coating process of the sheet material, and improve the yield of the sheet material coating process.

[0051] It is understood that the sub-slots are opened on the side of the positioning member 412 so that the two sub-slots can approach each other along the length of the furnace body structure 100 and allow the connecting line 22 to enter the positioning slot 411; in this way, the probability of structural interference between the positioning member 412 and the electrode plate 30 when it is close to the connecting line 22 can be reduced, and the ease of installation of the positioning assembly 41 can be improved.

[0052] In the embodiments of this application, the number of quick-release mechanisms 40 and the number of positioning components 41 in each quick-release mechanism 40 are not specifically limited.

[0053] For example, each first housing 11 corresponds to a heating field mechanism 20, and multiple mounting ports 111 can be provided on each first housing 11. These mounting ports 111 can be arranged along the length of the furnace structure 100. Each mounting port 111 can be provided with a quick-release mechanism 40. Each quick-release mechanism 40 can include two positioning components 41, which can be spaced apart in the circumferential direction. Two connecting lines 22 can pass through the positioning groove 411 of each positioning component 41, and these connecting lines 22 are spaced apart along the length of the furnace structure 100. Each positioning component 41 can support two electrode plates 30, and the two electrode plates 30 are respectively supported on two positioning members 412 of the positioning component 41. Each electrode plate 30 is detachably connected to its corresponding positioning member 412, and each electrode plate 30 is welded and electrically connected to a corresponding connecting line 22.

[0054] It is understood that the number of mounting ports 111 on each first housing 11 may be the same or different, and the embodiments of this application do not limit this. For example, among a plurality of first housings 11, three mounting ports 111 are provided on the first housings 11 located at both ends in the length direction of the furnace structure 100, and two mounting ports 111 are provided on the remaining first housings 11.

[0055] It is understood that the positioning element 412 can be made of insulating material. In the embodiments of this application, the material of the positioning element 412 is not specifically limited. For example, the positioning element 412 can be, but is not limited to, a ceramic material.

[0056] In some embodiments, an isolation sleeve 221 is fitted onto each connecting wire 22, and the isolation sleeve 221 is made of insulating material. The isolation sleeve 221 is located on the outside of the corresponding insulation layer 21. The isolation sleeve 221 can be accommodated in the corresponding positioning groove 411.

[0057] In the embodiments of this application, the material of the isolation sleeve 221 is not specifically limited. For example, the material of the isolation sleeve 221 may be, but is not limited to, ceramic.

[0058] It is understood that the isolation sleeve 221 is fitted onto the connecting line 22 so that the isolation sleeve 221 can block the connection line 22 from the positioning component 41, so that the connection line 22 does not have direct contact with the positioning component 41, thereby improving the insulation effect between the connection line 22 and the positioning component 41 and reducing the probability of short circuit in the thermal field mechanism 20.

[0059] Please refer to the following: Figure 5 In some embodiments, the furnace body structure 100 further includes multiple cover plates 50. The multiple cover plates 50 can be respectively configured to correspond to multiple mounting ports 111. Each cover plate 50 is detachably connected to a corresponding first housing 11, and each cover plate 50 can cover the corresponding mounting port 111. Each positioning element 412 can be located on a corresponding cover plate 50. Each cover plate 50 can have a positioning port 51 corresponding to a positioning groove 411, and a connecting line 22 can extend from the positioning port 51 and pass through the positioning groove 411.

[0060] It is understandable that when installing the cover plate 50, the operator can rotate the cover plate 50 to allow the electrode piece 30, which is already connected to the connecting wire 22, to pass through the positioning opening 51 on the cover plate 50, so that the connecting wire 22 can pass through the positioning opening 51. The length of the positioning opening 51 can be greater than or equal to the length of the positioning groove 411, the width of the positioning opening 51 can be greater than or equal to the width of the positioning groove 411, and the maximum or minimum cross-sectional area of ​​the positioning opening 51 is equal to the cross-sectional area of ​​the positioning groove 411.

[0061] In some cases, the positioning element 412 can be connected to the corresponding insulation layer 21 by screws, which can pass through the corresponding cover plate 50, so that the positioning element 412 can be located on the corresponding cover plate 50 and maintain the connection with the corresponding insulation layer 21.

[0062] In other cases, the positioning element 412 can be connected to the corresponding cover plate 50 by screws, the cover plate 50 can be connected to the corresponding insulation layer 21 by screws, and the screws connecting the cover plate 50 and the insulation layer 21 can pass through the first housing 11 to realize the connection between the cover plate 50 and the first housing 11.

[0063] In other cases, the positioning element 412 can be connected to the corresponding cover plate 50 by screws, the cover plate 50 can be connected to the corresponding first housing 11 by screws, the first housing 11 can be covered on the corresponding thermal field mechanism 20 and kept relatively fixed to the thermal field mechanism 20, so that the positioning element 412 can be indirectly and detachably connected to the corresponding insulation layer 21.

[0064] It is understandable that the cover plate 50 can accommodate multiple quick-release mechanisms 40 corresponding to the mounting openings 111 covered by the cover plate 50.

[0065] In other embodiments, the furnace body structure 100 may include a plurality of cover plates 50, which correspond one-to-one with a plurality of first housings 11. Each cover plate 50 can simultaneously cover all the mounting openings 111 on the corresponding first housing 11, and each quick-release mechanism 40 on the first housing 11 is located on the cover plate 50.

[0066] In some embodiments, each positioning element 412 may include a base 4121 and a boss 4122. The base 4121 is detachably connected to the corresponding insulation layer 21. A sub-slot may be formed on each base 4121. The boss 4122 is fixedly connected to the base 4121 on the side facing away from the insulation layer 21. The end of the boss 4122 facing away from the base 4121 is the top of the boss 4122 in its height direction. The top of the boss 4122 may receive an electrode sheet 30. The end of each connecting wire 22 extending out of the corresponding sub-slot may extend to the top of the boss 4122 and be welded and fixed to the electrode sheet 30.

[0067] Each electrode plate 30 may include a connecting portion 31, a first extension portion 32, and a second extension portion 33. The connecting portion 31 can abut against the side of the corresponding boss 4122 and is relatively fixed to the boss 4122 by a first mounting member 42. The first extension portion 32 and the second extension portion 33 are both located on the side of the connecting portion 31 near the top of the corresponding boss 4122, and the first extension portion 32 extends along the width direction of the boss 4122, while the second extension portion 33 and the connecting portion 31 both extend along the height direction of the boss 4122. The first extension portion 32 is received at the top of the boss 4122 and is welded and fixed to the corresponding connecting line 22. The second extension portion 33 protrudes from the top of the corresponding boss 4122 and can be detachably connected to the power supply line (not shown) of an external power source.

[0068] In the embodiments of this application, the fixing method during fixed connection and fixed installation is not specifically limited. For example, the fixing method may include, but is not limited to, welding fixing, bolt fixing, screw fixing, and integral molding fixing.

[0069] It is understood that the first mounting member 42 can be provided with a boss 4122 and a connecting part 31 to achieve a detachable connection between the positioning member 412 and the electrode plate 30.

[0070] For example, the second extension 33 can be connected to the power supply line of an external power source via the second mounting member 43. The second mounting member 43 can be a bolt, and the second extension 33 can pass through the screw portion of the second mounting member 43. The bolt portion of the second mounting member 43 can cooperate with the second extension 33 to clamp the power supply line, thereby realizing the connection between the second extension 33 and the power supply line.

[0071] In some cases, the second extension 33 can be electrically connected to the power supply line of the external power source and remain relatively fixed. The current from the external power source can be transmitted through the second extension 33 to the first extension 32 and through the connecting line 22 to the heating element.

[0072] In other cases, the second extension 33 is kept relatively fixed to the power supply line of the external power source, and the power supply line can be electrically connected to the first extension 32. The current from the external power source can be transmitted to the heating element through the first extension 32 and the connecting line 22.

[0073] In the embodiments of this application, the material of the electrode sheet 30 is not specifically limited. For example, the material of the electrode sheet 30 can be, but is not limited to, a copper alloy.

[0074] In some embodiments, each quick-release mechanism 40 may further include a positioning piece 44. The number of positioning pieces 44 in each quick-release mechanism 40 may be the same as the number of electrode pieces 30 connected to the quick-release mechanism 40. Multiple positioning pieces 44 may correspond one-to-one with multiple connecting lines 22. Each positioning piece 44 may abut against the corresponding connecting line 22 and is located on one side of the corresponding boss 4122. Each positioning piece 44 may be detachably connected to the corresponding boss 4122 and cooperates with the boss 4122 to clamp the corresponding connecting line 22, so that the portion of the connecting line 22 located between the electrode piece 30 and the insulation layer 21 can remain relatively fixed with the corresponding boss 4122, reducing the probability of the connecting line 22 detaching from the electrode piece 30 due to swinging.

[0075] For example, the positioning piece 44 can be connected to the boss 4122 via the first mounting member 42. The first mounting member 42 can be a bolt, and the threaded portion of the first mounting member 42 can pass through the positioning piece 44, as well as through the boss 4122 and the connecting portion 31 corresponding to the positioning piece 44. The head of the threaded portion of the first mounting member 42 can abut against the connecting portion 31; the nut portion of the first mounting member 42 can be tightened onto the threaded portion and abut against the positioning piece 44. In this way, the first mounting member 42 can simultaneously achieve the relative fixation of the connecting member 412 and the electrode piece 30 and the positioning piece 44 located on the connecting member 412.

[0076] In the furnace structure 100 provided in the embodiments of this application, when a heating element 20 needs to be replaced, the operator can remove the quick-release mechanism 40 and cover plate 50 corresponding to the heating element 20 from the outer shell 10, exposing the mounting opening 111 on the corresponding first shell 11. Then, the operator can remove the first shell 11 covering the row of heating elements 20, forming a notch on the outer shell 10. The operator can then remove the heating element 20 to be replaced from the notch and insert the new heating element 20 into the second shell 12 through the notch. During the manufacturing process, each connecting wire 22 of the new heating element 20 has an electrode plate 30 welded to one end extending from the insulation layer 21.

[0077] Then, the operator can place the first housing 11 onto the installed thermal field mechanism 20 and connect the first housing 11 to the second housing 12. The connecting wire 22 and the electrode plate 30 can pass through the corresponding mounting opening 111 on the first housing 11 during installation. Next, the operator places the cover plate 50 over the corresponding mounting opening 111 and installs the corresponding positioning component 41 on the cover plate 50. The operator moves the two positioning components 412 closer together along the length of the furnace structure 100 and inserts the two adjacent connecting wires 22 into the positioning groove 411 formed by the sub-grooves of the two positioning components 412. When the two positioning components 412 are in contact, the operator can fix the positioning components 412 to the furnace structure 100 with screws. Then, the operator can fix the connecting wire 22 to the positioning component 41 using the third mounting component 45, and use the second mounting component 43 to achieve relative fixation and electrical connection between the external power supply line and the electrode plate 30. At this point, the replacement of the heating mechanism 20 is complete, and the furnace structure 100 can be started to perform coating processing on sheet materials.

[0078] With the furnace structure 100 and reactor provided by the embodiments of this application, when a heating element ages or is damaged, the operator can disassemble the corresponding first shell 11 from the second shell 12 and remove the corresponding thermal field mechanism 20 from the notch formed on the outer shell 10 after the first shell 11 is disassembled. The operator can then inspect and repair the heating element within the thermal field mechanism 20. Thus, when a heating element needs to be replaced or repaired, the operator can remove the corresponding thermal field mechanism 20 separately without disassembling other thermal field mechanisms 20, improving the convenience of disassembling and replacing the thermal field mechanism 20.

[0079] Workers can install the new heating element 20 inside the outer shell 10 through the notch on the outer shell 10. Before the heating element 20 is installed inside the outer shell 10, the connecting wire 22 can be pre-welded and fixed to the corresponding electrode plate 30, establishing an electrical connection. Then, when the heating element 20 is installed inside the second shell 12, and the first shell 11 is installed on the second shell 12, the connecting wire 22 and the electrode plate 30 can be connected to the second shell 12 through the corresponding mounting port 111 on the first shell 11 without interference from the quick-release mechanism 40. When the heating element 20 is installed on the outer shell 10, the electrode plate 30 is installed simultaneously. This improves the ease of installation of the heating element 20 at the furnace structure 100 site, reduces the on-site welding process of the connecting wire 22 and the electrode plate 30, and improves the installation efficiency of the heating element 20; at the same time, it avoids replacing the entire insulation layer 21 when a heating element needs to be replaced, thus reducing the maintenance cost of the furnace structure 100.
