Description

Technical Field

[0001] This invention belongs to the field of burner technology, and specifically discloses a cyclone-type silicon carbide burner. Background Technology

[0002] In high-temperature combustion scenarios in industrial furnaces, cyclone burners have become one of the core thermal equipment due to their ability to enhance fuel-air mixing efficiency through spiral airflow. These burners need to withstand high-temperature environments of 1200-1600℃ for extended periods, requiring stable airflow supply and reliable impurity interception. Therefore, the industry commonly uses silicon carbide to manufacture the burner body, which possesses excellent high-temperature resistance (refractory ≥1600℃), thermal shock resistance (rapid cooling and heating temperature difference ≥800℃), and chemical stability, effectively preventing oxidation and corrosion at high temperatures and extending the burner's service life. However, existing cyclone-type silicon carbide burners still suffer from three major technical challenges in actual operation, severely limiting combustion efficiency and ease of maintenance: The ventilation channels of existing burners are mostly cylindrical structures. Although air dimmers are installed to regulate the air volume, the airflow is easily obstructed by the channel wall and local vortex interference, resulting in a severe uneven distribution of air volume from the rear splitter to each intake pipe. Some technologies have attempted to alleviate the airflow deviation by adding multiple sets of air dimmers, but this has instead led to the formation of new vortices due to repeated airflow impacts, further exacerbating the uneven air volume. Ultimately, this results in excessive air volume in the intake pipes near the air dimmer (which can easily cause incomplete combustion of fuel) and insufficient air volume in the intake pipes far from the air dimmer (resulting in a yellow flame at the combustion nozzle and a decrease in thermal efficiency). At the same time, the offset of the flame center can also cause local overheating of the silicon carbide cylinder wall, shortening its service life. As a key component for intercepting dust and carbon particles in the air, the grid is prone to clogging of the ventilation holes after long-term use. However, the existing cleaning methods mostly involve manual disassembly and cleaning after shutdown, which takes a long time for each maintenance and significantly increases the downtime cost of the equipment. In addition, manual cleaning can easily damage the ventilation structure of the silicon carbide grid due to the scraping of tools, resulting in a decrease in the grid filtration accuracy. Combustion chambers of burners are typically connected to multiple intake pipes (each corresponding to a combustion nozzle). When a combustion failure occurs due to abnormal airflow in an intake pipe (flow deviation or grid blockage), existing detection methods have significant drawbacks: when observed manually, it is difficult to distinguish the flame status of each nozzle at close range in the high-temperature environment of the combustion chamber, and the visual recognition of yellow flames is easily affected by smoke, resulting in a high misjudgment rate. Furthermore, fixed-point infrared detection can only cover a part of the combustion chamber and cannot accurately locate the fault of a single intake pipe. Each intake pipe must be disassembled for inspection, resulting in extremely low maintenance efficiency.

[0003] Therefore, existing cyclone-type silicon carbide burners have technical shortcomings in three core aspects: stable airflow supply, impurity blockage removal, and combustion fault location. They are unable to meet the industrial requirements for efficient combustion, low maintenance costs, and high reliability, and structural innovation is urgently needed to overcome these bottlenecks. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the background art, and to propose a cyclone-type silicon carbide burner, including an air inlet device, a ventilation chamber, a combustion chamber, an ignition device, an infrared detection mechanism, and a cyclone chamber. The two sides of the cyclone chamber are respectively connected to the air inlet device and the ventilation chamber. One side of the combustion chamber is connected to the other side of the ventilation chamber through a fixedly installed transparent ring tube. A combustion mechanism is provided inside the combustion chamber. An air regulating mechanism is provided inside the cyclone chamber and on the side of the air regulating mechanism. A grid is fixedly installed inside the cyclone chamber and on the side of the air regulating mechanism. Multiple sets of ventilation square holes are opened at the top and bottom inside the grid. A secondary rotating shaft is rotatably connected to the middle of the grid. A cyclone ring is fixedly installed at one end of the secondary rotating shaft. Cyclone vanes are connected at equal intervals along the circumference on the side of the cyclone ring facing the grid. A protective cylinder is connected to the side of the cyclone ring away from the cyclone vanes through a set mounting component. The infrared detection mechanism is fixedly installed at the front end inside the protective cylinder. A control system receiver and positioner is fitted on the outside of the protective cylinder.

[0005] In the above technical solution, the air regulating mechanism further includes frame rods fixedly installed on both sides of the outside of the cyclone chamber. Each of the two frame rods has a mounting bracket fixedly installed on its exterior near the top and bottom ends. Two sets of mounting brackets arranged laterally symmetrically are connected by an air regulating shaft that rotates through them. Both ends of the air regulating shaft pass through the outside of the cyclone chamber. An air regulating plate is fixedly inserted inside the air regulating shaft and within the cyclone chamber. The outer sides of one end of the two air regulating shafts are connected by a shared transmission belt assembly. A motor is fixedly installed at the upper end of the air regulating shaft. A base is fixedly installed on one side of the motor, and the other side of the base is connected to the outside of the cyclone chamber. The grid is located on the side of the air regulating plate away from the air inlet device. A V-shaped folding plate is fixedly installed inside the cyclone chamber near the two sets of air regulating plates.

[0006] In the above technical solution, the combustion mechanism further includes an air-gathering ring fixedly installed in the middle of the combustion chamber, a swirl plate fixedly installed inside the air-gathering ring, combustion nozzles equidistantly installed in the combustion chamber along the circumferential direction, the combustion nozzles all spraying in the direction of the swirl plate, and an air intake pipe connected to the lower part of the combustion chamber.

[0007] In the above technical solution, a movable frame is further provided inside the swirl chamber and on one side of the grid. The side of the movable frame away from the grid is slidably engaged with the inside of the ventilation chamber through an elastic element correspondingly provided at the corner.

[0008] In the above technical solution, the elastic element further includes a slide rod slidably installed inside the ventilation chamber, a spring is fitted on the outside of the slide rod and on one side of the ventilation chamber, the end of the slide rod is connected to the outside of the movable frame, and a blocking mechanism is provided inside the movable frame.

[0009] In the above technical solution, the unblocking mechanism further includes movable seats that are slidably installed at the upper and lower ends inside the movable frame. A connecting seat is fixedly installed at the corner of the outer wall on the side away from the grid of each of the two movable seats. The two sets of connecting seats are connected by a bidirectional telescopic cylinder that is commonly provided.

[0010] In the above technical solution, further, multiple sets of through slot blocks are fixedly installed on the side of the movable seat facing the grid. The multiple sets of through slot blocks are corresponding to the ventilation square holes arranged horizontally inside the grid. Each through slot block has an arc-shaped groove inside. A retaining shaft is horizontally embedded on the outer surface of the through slot block. A roller is rotatably installed outside the retaining shaft and located at the arc-shaped groove. Ball bearings are rotatably embedded in both the upper and lower parts inside the through slot block.

[0011] In the above technical solution, the mounting component further includes a fixing plate fixedly installed on the side of the swirl ring away from the swirl vanes, a clamping sleeve fixedly installed on the outside of the fixing plate, a clamping rod inserted inside the clamping sleeve, a clamping seat fixedly installed on the side of the clamping rod away from the clamping sleeve, and an annular shell connected inside the clamping seat through an inserted connecting rod, and the protective cylinder being clamped inside the annular shell.

[0012] In the above technical solution, a first bevel gear is fixedly mounted on the outside of the auxiliary shaft, a second bevel gear is meshed with the upper side of the first bevel gear, a main shaft is fixedly inserted inside the second bevel gear, one end of the main shaft extends to the top of the ventilation chamber, an electric drive device is connected to the end of the main shaft, and the electric drive device is fixedly installed on the top of the ventilation chamber.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Precise airflow control is achieved through the coordinated design of the air-adjusting mechanism and the swirl assembly. In the air-adjusting mechanism, the motor drives the dual air-adjusting shafts to rotate synchronously, which in turn drives the air-adjusting plates to adjust the air intake volume. The V-shaped baffles in the swirl chamber first guide the airflow, preventing the airflow from directly impacting the chamber wall and forming local vortices. At the same time, the electric drive unit drives the swirl ring and swirl vanes to rotate at high speed through the bevel gear transmission of the main and auxiliary shafts. The swirl vanes generate spiral airflow, which evenly gathers the adjusted airflow at the rear end of the grid, effectively offsetting the effect of flow deviation. After the uniform airflow is delivered to the combustion chamber through the ventilation chamber, the mixing of fuel and air is further enhanced by the air-gathering ring and swirl plate, effectively avoiding incomplete combustion caused by excessive airflow and yellow flame caused by insufficient airflow. At the same time, it prevents local overheating of the silicon carbide cylinder wall caused by the displacement of the flame center in the combustion chamber, thus extending the service life of the burner body.

[0014] 2. The automatic unblocking mechanism and elastic element work together to achieve continuous unblocking of the grid without stopping the machine. The bidirectional telescopic cylinder drives the movable seat to slide up and down along the outside of the moving frame, moving the through-slot block closer to the grid. The roller on the through-slot block can accurately insert into the vent hole of the grid, cleaning impurities inside the hole as the movable seat moves. The ball bearings inside the through-slot block reduce frictional resistance with the inside of the grid, preventing damage to the grid during cleaning. The spring in the elastic element provides continuous clamping force to the moving frame through the slide rod, ensuring that the roller is always in contact with the grid's square hole for more thorough cleaning. This design eliminates the need for manual operation during machine downtime, significantly reducing production interruption time, lowering the intensity and cost of manual maintenance, and avoiding the hard damage to the silicon carbide grid caused by manual cleaning, thus extending the grid's service life.

[0015] 3. Precise fault location is achieved through a rotating infrared detection structure. The infrared detection mechanism is installed inside the protective cylinder and rotates synchronously with the swirl ring, which can fully cover all combustion nozzles distributed around the combustion chamber and collect flame status data of each nozzle in real time. The protective cylinder can isolate the high temperature of the combustion chamber and ensure that the infrared detection mechanism can work stably in a high-temperature environment of 1200-1600℃. With the auxiliary positioning function of the receiver locator of the control system, the air intake pipe corresponding to the combustion nozzle with yellow flame can be quickly identified, solving the problem of interference from smoke gas during manual observation. At the same time, it avoids the tedious process of disassembling and checking each air intake pipe for fixed-point infrared detection, shortening the fault maintenance time, significantly reducing equipment downtime costs, and improving the convenience and reliability of maintenance.

Detailed Implementation

[0018] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0020] like Figures 1-11The cyclone-type silicon carbide burner shown includes an air inlet device 1, a ventilation chamber 2, a combustion chamber 3, an ignition device 9, an infrared detection mechanism 20, and a swirl chamber 43. The two sides of the swirl chamber 43 are connected to the air inlet device 1 and the ventilation chamber 2, respectively. One side of the combustion chamber 3 is connected to the other side of the ventilation chamber 2 via a fixedly installed transparent annular tube. A combustion mechanism is installed inside the combustion chamber 3. An air regulating mechanism is installed inside the swirl chamber 43, on the side closest to the air inlet device 1. A fixedly installed... There is a grid 13, and multiple sets of ventilation square holes are opened at the top and bottom inside the grid 13. A secondary rotating shaft 25 is rotatably connected in the middle of the grid 13. A swirl ring 12 is fixedly installed at one end of the secondary rotating shaft 25. Swirl plates 22 are connected at equal intervals along the circumference on the side of the swirl ring 12 facing the grid 13. A protective cylinder 16 is connected to the side of the swirl ring 12 away from the swirl plates 22 through a set mounting piece. An infrared detection mechanism 20 is fixedly installed inside the front end of the protective cylinder 16. A control system receiver locator 19 is fitted on the outside of the protective cylinder 16. In this embodiment, after the burner is started, external air first enters the swirl chamber 43 through the air inlet device 1. After the airflow is regulated by the subsequent air adjustment mechanism, it flows to the grid 13. The square ventilation holes of the grid 13 intercept impurities such as dust and carbon particles in the air, preventing impurities from entering the combustion chamber 3, adhering to the nozzle, and abrading the silicon carbide wall. At the same time, the auxiliary rotating shaft 25 rotates under the drive of external power, driving the swirl ring 12 and the swirl vane 22 to rotate synchronously. When the swirl vane 22 rotates at high speed, it cuts the airflow and generates a spiral airflow along the axial direction of the swirl chamber 43, which re-sorts and evens the airflow filtered by the grid 13, effectively offsetting the flow deviation problem caused by wall obstruction and vortex during the air adjustment process. The airflow is then stably transferred through the ventilation chamber 2 and enters the combustion chamber 3 through the transparent ring tube. The ignition device 9 ignites the fuel delivered by the combustion mechanism to complete the combustion. During this process, the infrared detection mechanism 20 rotates synchronously with the swirl ring 12 to collect the temperature of the flame in each area of ​​the combustion chamber 3 in real time. The protective cylinder 16 isolates the high temperature of the combustion chamber 3 (1200-1600℃) to prevent the infrared detection mechanism 20 from failing due to high temperature. The control system receiver locator 19 records the circumferential position of the infrared detection mechanism 20 in real time. When abnormal combustion of yellow flame is detected, the corresponding detection position can be quickly matched to locate the source of the fault.

[0021] The air regulating mechanism includes two support rods 29 fixedly installed on the outside of the cyclone chamber 43. Each of the two support rods 29 has a bracket 30 fixedly installed on its outside and near its upper and lower ends. The two sets of brackets 30 arranged laterally symmetrically are connected by an air regulating shaft 31 that rotates through each other. Both ends of the air regulating shaft 31 pass through the outside of the cyclone chamber 43. An air regulating plate 11 is fixedly inserted inside the air regulating shaft 31 and inside the cyclone chamber 43. The outer sides of one end of the two air regulating shafts 31 are connected by a transmission belt assembly. A motor 8 is fixedly installed at the end of the upper air regulating shaft 31. A base 10 is fixedly installed on one side of the motor 8. The other side of the base 10 is connected to the outside of the cyclone chamber 43. A grid 13 is located on the side of the air regulating plate 11 away from the air inlet device 1. A V-shaped folding plate 28 is fixedly installed inside the cyclone chamber 43 and near the two sets of air regulating plates 11. In this embodiment, when it is necessary to adjust the air intake, the output shaft of the motor 8 drives the upper air adjustment shaft 31 to rotate. Since the two air adjustment shafts 31 are connected by a transmission belt assembly, the rotational power of the upper air adjustment shaft 31 is synchronously transmitted to the lower air adjustment shaft 31, so that the two air adjustment shafts 31 rotate in the same direction and at the same speed. When the air adjustment shaft 31 rotates, it drives the air adjustment plate 11 on its inner side to rotate synchronously. The angle between the air adjustment plate 11 and the inner wall of the vortex chamber 43 changes with the rotation. When the angle increases, the air intake channel widens and the air volume increases; when the angle decreases, the air intake channel narrows and the air volume decreases, thereby achieving precise control of the total air intake.

[0022] The combustion mechanism includes a concentrating ring 4 fixedly installed in the middle of the combustion chamber 3. A swirl plate 18 is fixedly installed inside the concentrating ring 4. Combustion nozzles 17 are installed at equal intervals along the circumference inside the combustion chamber 3. The spray direction of the combustion nozzles 17 is all facing the inside of the swirl plate 18. An air intake pipe 5 is connected and installed at the bottom inside the combustion chamber 3. In this embodiment, the air-gathering ring 4 has a ring structure, which gathers the airflow delivered by the ventilation chamber 2 to the inside of the swirl plate 18. The swirl plate 18 has a spiral air guide groove to convert the gathered airflow into a swirl. The air intake pipe 5 can deliver fuel to each combustion nozzle 17.

[0023] A movable frame 15 is provided inside the vortex chamber 43 and on one side of the grid 13. The side of the movable frame 15 away from the grid 13 is slidably engaged with the inside of the ventilation chamber 2 via an elastic element corresponding to the corner. The elastic element includes a slide rod 26 slidably installed inside the ventilation chamber 2. A spring 39 is fitted on the outside of the slide rod 26 and on one side of the ventilation chamber 2. The end of the slide rod 26 is connected to the outside of the movable frame 15. A blocking mechanism is provided inside the movable frame 15. The blocking mechanism includes movable seats 23 slidably installed at the upper and lower ends inside the movable frame 15, respectively. The two movable seats 23 are away from the grid. Connecting seats 38 are fixedly installed at the corner of the outer wall of one side of grid 13. The two sets of connecting seats 38 are connected by a bidirectional telescopic cylinder 37. Multiple sets of through slot blocks 40 are fixedly installed on the side of movable seat 23 facing grid 13. The multiple sets of through slot blocks 40 are corresponding to the ventilation square holes arranged horizontally inside grid 13. Each through slot block 40 has an arc groove 27 inside. A retaining shaft 42 is horizontally embedded on the outer surface of through slot block 40. A roller sleeve 6 is rotatably installed on the outside of retaining shaft 42 and located at the arc groove 27. Balls 41 are rotatably embedded in the upper and lower parts of through slot block 40. In this embodiment, when the grid 13 is blocked by dust and other impurities in the air intake, thus affecting the airflow efficiency, the bidirectional telescopic cylinder 37 extends and retracts, pushing the movable seat 23 to slide up and down through the connecting seat 38. When the movable seat 23 slides, under the pressure of the spring 39, it can be ensured that the movable seat 23 always fits against one side of the outer surface of the grid 13. When the corresponding through-slot block 40 is on the plane, it rolls against the outer surface of the grid 13 through the roller sleeve 6. When the through-slot block 40 slides into the air intake, it will be precisely inserted into the inside of the through-slot block 40, thereby cleaning the impurities inside the air intake. When the through-slot block 40 slides out from the inside of the air intake, the ball bearings 41 embedded in the inside of the through-slot block 40 form rolling contact with the inner wall of the square hole of the grid 13, which greatly reduces frictional resistance and wear, making the cleaning process smooth and not easy to jam. It should be emphasized that during normal ventilation, the movable seat 23 retracts through the bidirectional telescopic cylinder 37, causing the movable seat 23 to stop away from the ventilation square hole, and the bottom of the inner side of the vortex chamber 43 is provided with a dust discharge channel to remove impurities.

[0024] The mounting components include a fixing plate 32 fixedly installed on the side of the swirl ring 12 away from the swirl vane 22, a clamping sleeve 33 fixedly installed on the outside of the fixing plate 32, a clamping rod 35 inserted inside the clamping sleeve 33, a clamping seat 36 fixedly installed on the side of the clamping rod 35 away from the clamping sleeve 33, and an annular shell 21 connected inside the clamping seat 36 through an inserted connecting rod 34, and a protective cylinder 16 clamped inside the annular shell 21. In this embodiment, by plugging and unplugging the connection between the locking rod 35 and the locking cylinder 33, the entire protective cylinder 16 and the internal precision infrared detection mechanism 20 can be quickly disassembled from the vortex ring 12 for calibration, repair and replacement. The protective cylinder 16 is made of high-temperature resistant quartz material, which has obvious light transmittance and high temperature resistance. The infrared rays of the infrared detection mechanism 20 can penetrate the front end of the protective cylinder 16. The control system receiver locator 19 has a built-in circumferential position sensor. When an abnormal flame temperature is detected, the position and angle of the control system receiver locator 19 can be observed with the help of a transparent ring tube. Subsequently, the combustion nozzles 17 in that area are matched to locate the faulty combustion nozzle 17.

[0025] The auxiliary shaft 25 is externally fixedly fitted with a first bevel gear 24. A second bevel gear 44 is meshed and connected above one side of the first bevel gear 24. The main shaft 14 is fixedly inserted inside the second bevel gear 44. One end of the main shaft 14 extends to the top of the ventilation chamber 2. An electric drive device 7 is connected to the end of the main shaft 14. The electric drive device 7 is fixedly installed on the top of the ventilation chamber 2. In this embodiment, the electric drive device 7 adopts a servo motor (with a gearbox), and its output shaft is rigidly connected to the main rotating shaft 14 through a coupling to ensure stable power transmission; the main rotating shaft 14 passes through the sealed bearing (high temperature mechanical seal, withstanding temperature ≥800℃, to prevent airflow leakage in the ventilation chamber 2) at the top of the ventilation chamber 2. When the electric drive unit 7 is started, the main shaft 14 drives the second bevel gear 44 to rotate. The second bevel gear 44 meshes with the first bevel gear 24 on the auxiliary shaft 25, converting the rotational power of the main shaft 14 into the rotational power of the auxiliary shaft 25. The vertical rotation of the main shaft 14 can be converted into the horizontal rotation of the auxiliary shaft 25, which is adapted to the horizontal airflow direction of the vortex chamber 43. When the auxiliary shaft 25 rotates, it synchronously drives the vortex rings 12 at both ends and the infrared detection mechanism 20 to rotate. The vortex plates 22 of the vortex rings 12 generate spiral airflow to achieve uniform airflow distribution. The infrared detection mechanism 20 rotates in a circle with the auxiliary shaft 25 to complete the flame temperature detection of the combustion nozzle 17 in the combustion chamber 3.

[0026] Working principle: External air enters the vortex chamber 43 through the air inlet device 1, and the motor 8 is started. The output shaft of the motor 8 drives the upper air regulating shaft 31 to rotate. The two air regulating shafts 31 rotate synchronously through the transmission belt assembly, which in turn drives the air regulating plate 11 inside the vortex chamber 43 to coordinately adjust the size of the air inlet channel, so as to achieve preliminary control of the air volume. The V-shaped baffle 28 inside the swirl chamber 43 initially guides the airflow after air adjustment, preventing the airflow from directly impacting the chamber wall and forming local vortices. At the same time, the electric drive device 7 on the top of the ventilation chamber 2 is activated, and its output shaft drives the main rotating shaft 14 to rotate. The main rotating shaft 14 is driven by the meshing of the first bevel gear 24 on the auxiliary rotating shaft 25 through the second bevel gear 44, so that the auxiliary rotating shaft 25 rotates inside the grid 13. The swirl ring 12 at one end of the auxiliary rotating shaft 25 rotates with the shaft, and the swirl vanes 22 on the swirl ring 12 rotate at high speed to generate spiral airflow, which effectively counteracts the deflection that may occur during the air adjustment process and ensures that the airflow flows stably to the ventilation chamber 2. When the venting holes of the grid 13 become clogged due to the accumulation of impurities, the moving frame 15 is kept in a pressed state towards the grid 13 by the elastic element. The spring 39 is fitted on the outside of the slide rod 26 to provide continuous pressure to the moving frame 15. The bidirectional telescopic cylinder 37 inside the moving frame 15 is activated. The bidirectional telescopic cylinder 37 drives the upper and lower movable seats 23 to slide along the moving frame 15 through the connecting seats 38 at both ends. The through-slot block 40 on the side of the movable seat 23 facing the grid 13 moves with the movable seat 23. The roller 6 inside the through-slot block 40 is inserted into the venting holes of the grid 13 to remove the blockage impurities in the holes. The ball 41 inside the through-slot block 40 can reduce the frictional resistance of the through-slot block 40 when it moves with the surface of the grid 13, avoid damage to the grid 13 during the cleaning process, realize the grid 13 to be automatically unblocked without stopping, and ensure the airflow efficiency. The airflow that is stably delivered through the ventilation chamber 2 can be easily observed by setting a transparent ring tube on one side of the combustion chamber 3 to observe the position of the control system receiver positioner 19; The airflow enters the combustion chamber 3 and is first gathered by the air-gathering ring 4 in the middle of the combustion chamber 3. Then, it forms a spiral airflow through the swirl plate 18 inside the air-gathering ring 4, providing a power basis for the mixing of fuel and air. Fuel is delivered to each combustion nozzle 17 through the air intake pipe 5 below the combustion chamber 3. The combustion nozzles 17 are evenly distributed along the circumference of the combustion chamber 3, and the nozzles spray out in the direction of the inside of the swirl plate 18. When the ignition device 9 is activated, the fuel is fully mixed with air under the action of the spiral airflow of the swirl plate 18 to form a stable blue flame, avoiding the problem of yellow flame and incomplete combustion caused by insufficient air, and improving combustion efficiency. The infrared detection mechanism 20 is fixed to the side of the swirl ring 12 away from the swirl vane 22 by the mounting parts. The protective cylinder 16 isolates the high temperature of the combustion chamber 3 to ensure the stable operation of the infrared detection mechanism 20. The infrared detection mechanism 20 rotates synchronously with the swirl ring 12 to monitor the temperature of each combustion nozzle 17 in the combustion chamber 3 in real time. The control system receiver 19 outside the protective cylinder 16 helps to record the detection position. When a combustion nozzle 17 has an abnormal air intake (such as partial blockage of the grid 13 or yellow flame due to airflow deviation), the infrared detection mechanism 20 quickly identifies the flame temperature. Combined with the position information of the control system receiver 19, it accurately locates the fault of the corresponding air intake pipe 5, which is convenient for staff to troubleshoot and maintain in a timely manner.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
