Description

Technical Field

[0001] The present invention relates to the technical field of boiler burners, and in particular to a high-performance boiler burner. Background Art

[0002] The boiler burner is the most important equipment in the auxiliary equipment of oil and gas boilers. Its function is to mix fuel and air in an appropriate proportion and burn them in the combustion chamber to provide the heat required for boiler operation. Burners are classified according to the fuel: oil burners and gas burners. Oil burners can be divided into light oil burners and heavy oil burners. Light oil mainly refers to diesel, and heavy oil refers to the heavy oil left after gasoline and diesel are extracted from crude oil. Gas burners can be divided into natural gas burners, city gas burners, liquefied petroleum gas burners and biogas burners.

[0003] The burner is mainly composed of an air supply system, an igniter, a detection system, a fuel system and a control system. The air supply system sends air with a certain wind speed and volume to the combustion chamber. It is mainly composed of a shell, a fan motor, a fan impeller, an air gun fire tube, a damper controller and a diffusion disk. The fan impeller is driven by the fan motor to rotate, thereby drawing the outside air into the shell, and the air flow is mixed with the fuel inside the air gun fire tube for combustion. The ignition system is used to ignite the mixture of air and fuel, and is mainly composed of an ignition transformer, an ignition motor and an ignition cable. The detection system is used to detect the pressure, flame and temperature inside the shell. Measurement helps the staff understand the combustion status of the fuel inside the burner, and the fuel system ensures the delivery of the required fuel. It is mainly composed of oil pipes, joints, oil pumps, solenoid valves, nozzles and preheaters. The fuel inside the oil pipe is preheated by the preheater, and then the oil pump is pumped and the delivery volume of the solenoid valve is controlled to make the dye sprayed into the inside of the air gun fire tube through the nozzle to achieve the mixing of fuel and air, and cooperate with the ignition system to ignite the fuel. The control system is used to carry out linkage control between the assembly components between the air supply system, igniter, detection system and fuel system to ensure that the combustion status of the fuel meets the requirements.

[0004] Although the burners in the prior art have many benefits during use, the following problems still exist: the control of the flow trajectory of the airflow inside the shell and the air gun fire tube is not perfect. The airflow inside the shell can only flow along its internal shape, and the fuel cannot be adjusted in different combustion processes, which affects the adaptability of the burner to the combustion process, thereby affecting the heating efficiency of the internal temperature of the boiler. Summary of the Invention

[0005] In view of the problems in the prior art, the present invention provides a high-performance boiler burner.

[0006] The technical solution adopted by the present invention to solve the technical problem is a high-performance boiler burner, which includes a combustion mechanism, an air gathering mechanism, a driving mechanism, a flow guiding mechanism and a dispersing mechanism;

[0007] The wind gathering mechanism is composed of a wind shield and a plurality of conical wind gathering covers, and the plurality of conical wind gathering covers are distributed in a circular array on the leeward side of the wind shield;

[0008] The driving mechanism is composed of two piston tubes and two piston rods. The two piston tubes are distributed on both sides of the windshield, and the piston rods are movably installed inside the piston tubes.

[0009] The guide mechanism is composed of a driving rod and a plurality of diverter plates, and the center of the driving rod and the center of the wind shield are in the same horizontal plane;

[0010] The dispersion mechanism is composed of a spoiler and a plurality of ventilation holes. The spoiler is located on the windward side of the wind shield, and the plurality of ventilation holes are arranged inside the spoiler in a circular array.

[0011] By adopting the above technical solution, the wind baffle blocks the air flow trajectory inside the shell and can guide the air through the conical ventilation channel formed by the convergence of multiple conical wind hoods, ensuring that when the fuel is initially burned inside the burner, a high-speed and high-pressure airflow is provided to the fuel ignition position, which helps to increase the combustion-supporting air volume required for combustion, optimize the combustion efficiency, and meet the rapid temperature increase inside the boiler at the initial stage of combustion. As the fuel inside the air gun fire tube continues to burn, the temperature provided to the inside of the boiler meets the requirement and tends to stabilize. The temperature inside the air gun fire tube will heat and vaporize the liquid inside the piston tube, and drive the piston plate and piston rod to move horizontally, providing power for subsequent dynamic adjustment of the air flow, thereby carrying the connecting rod and the driving rod to move synchronously until the guide plate and the diverter plate enter the air supply pipe. During the movement, the driving rod pushes the conical wind hood to rotate around the hinge through the sleeve and the linkage rod until the conical wind hoods unfold to make the air supply pipe The flow trajectory of the internal airflow is expanded, and the guide plate and the diverter plate disperse the flow direction of the airflow, so that the airflow forms a multi-angle dispersed air outlet, ensuring sufficient contact and mixing of air and fuel in a larger range, ensuring the uniformity and sufficiency of fuel combustion, and ensuring the stability and accuracy of the combustion temperature, so that it can adapt to different combustion conditions. When the drive rod moves, the spiral shape of the guide groove can cooperate with the guide rod to drive the baffle to rotate in a circle inside the limit block until the position of the ventilation hole overlaps with the position of the diverter pipe, so that the airflow on the windward side of the wind shield is dispersed through the diverter pipe to achieve multi-point air outlet, and due to the inclination angle of the diverter pipe, the airflow impacts the airflow discharged from the inside of the air supply pipe, thereby reducing the impact intensity of the airflow, and causing the fine airflow to disturb the large flow airflow inside the air supply pipe, thereby achieving a stronger turbulent mixing effect between the subsequent air and fuel, further improving the mixing uniformity of air and fuel, and further improving the combustion sufficiency of the fuel.

[0012] Specifically, the combustion mechanism is composed of a shell and an air gun fire tube. The outer wall of the shell is welded with an air inlet cover, which is connected to the inside of the shell. The outer side of the air inlet cover is screwed with an air inlet grille that is useful for filtering foreign matter.

[0013] An inspection plate is screwed to one side of the outer wall of the upper end of the shell, and an inspection hole adapted to the size of the inspection plate is opened on the outer wall of the upper end of the shell, and the inspection plate corresponds to the position of the windshield.

[0014] By adopting the above technical solution, the fan impeller used inside the shell can be driven to rotate by the external fan motor, thereby introducing outside air through the air inlet cover until the air flows into the air gun fire tube through the outer shell and the wind shield and mixes with the fuel. The air inlet grille can filter foreign matter in the air and prevent impurities from entering the combustion chamber. The inspection plate and inspection hole make it convenient for the staff to dismantle the inspection plate and then inspect and maintain the wind gathering mechanism, drive mechanism, guide mechanism and dispersion mechanism.

[0015] Specifically, the air gun fire tube is screwed to the outer wall of the shell, and the air gun fire tube is connected to the interior of the shell;

[0016] An igniter is provided on one side of the inner wall of the air gun fire tube, and an oil pipe is provided on one side of the outer wall of the shell. The end of the oil pipe penetrates into the air gun fire tube, and the end of the oil pipe corresponds to the position of the igniter.

[0017] By adopting the above technical solution, the matching oil pump provides an oil pipe to transport fuel to the inside of the burner, and the nozzle used at the end of the oil pipe sprays the fuel. In conjunction with the igniter, the fuel injection and ignition timing can be accurately controlled to ensure that the fuel and air are quickly ignited after mixing, thereby improving the ignition success rate and combustion efficiency.

[0018] Specifically, an air supply pipe is welded inside the windshield, and a hinge is provided on the outer wall of the air supply pipe away from the windshield, and the other end of the hinge is connected to the outer wall of the conical wind collecting cover, and the conical wind collecting cover is rotatably connected to the air supply pipe through the hinge;

[0019] The inner wall of the conical wind collecting cover and the outer wall of the driving rod are both installed with ferrules, and the ferrules are distributed in a circular array on the outer wall of the driving rod. The pin inside the ferrule is connected to a linkage rod for driving rotation. The conical wind collecting cover is connected to the driving rod through the ferrule and the linkage rod.

[0020] By adopting the above technical solution, the wind shield is welded to the inner wall of the shell to ensure that the wind shield is stably positioned inside the shell. The conical wind collecting hood is rotatably connected to the air supply pipe through a hinge, and the coupling rod and the drive rod are connected by a sleeve. The movement of the drive rod can drive the angle of the conical wind collecting hood to be adjusted, dynamically changing the wind collecting direction and the degree of airflow convergence to adapt to combustion requirements under different loads.

[0021] Specifically, a heat insulation pad for reducing temperature transfer efficiency is bonded and fixed to the outer wall of the piston tube, and the heat insulation pad is located on the leeward side of the windshield;

[0022] Connectors are installed on both sides of the outer wall of the upper end of the piston tube, and the piston tube is screwed to the leeward side of the windshield through the connectors;

[0023] The outer wall of one end of the piston rod is screwed to a piston plate, and a sealing ring is bonded and fixed to the outer wall of the piston plate and one side of the inner wall of the piston tube. The gap between the piston plate and the piston tube is filled by the sealing ring, and the gap between the piston rod and the piston tube is filled by the sealing ring;

[0024] The end of the piston rod away from the piston plate is screwed to a connecting rod, and the connecting rod is screwed to the driving rod.

[0025] By adopting the above technical solution, the thermal insulation pad reduces the temperature transfer of the piston tube and reduces the heat vaporization rate of the liquid inside the piston tube, thereby ensuring that when the connecting rod moves, the temperature inside the boiler has been heated to the required temperature, thereby achieving the purpose of controlling the movement time of the drive rod. The liquid inside the piston tube exists between the two sealing rings, so that after the liquid is heated and vaporized and expanded, it will push the piston plate to move horizontally inside the piston tube. The sealing ring blocks the liquid to ensure the sealing during the liquid vaporization process. After the device is not in use, the vaporized liquid condenses, and due to the incompressibility of the liquid, it will pull the piston plate to reset inside the piston rod. The piston rod is fixed to the drive rod through the connecting rod, and the linear motion of the piston is converted into the swing of the linkage rod, which can drive the conical wind hood or baffle to move.

[0026] Specifically, a guide plate for dispersing airflow is welded on the outer wall of one side of the driving rod, and the outer wall of the guide plate is designed in an inclined shape;

[0027] The plurality of diverter plates are welded to the outer wall of the guide plate in a circular array state, and the plurality of diverter plates are used to separate the air supply areas.

[0028] By adopting the above technical solution, the inclined design of the guide plate can guide the airflow in a specific direction, reducing airflow resistance. The circular array of diverter plates divides the airflow into multiple tributaries, further refining the airflow distribution, making the air and fuel mix more fully and ensuring complete combustion.

[0029] Specifically, a circular array of limit blocks is provided on the outside of the spoiler. The limit blocks are designed in an L-shape and are screwed to the windward side of the wind shield. The spoiler is away from the limit blocks to limit the rotation position.

[0030] By adopting the above technical solution, the multi-point limit blocks can limit the position of the spoiler and ensure that the position of the spoiler is relatively stable when it is driven to rotate, thereby ensuring that the spoiler works stably in the set position.

[0031] Specifically, a sealing gasket for providing sealing is bonded and fixed to the outer wall of the spoiler, the other side of the sealing gasket contacts the windward surface of the windshield, and a hole adapted for the ventilation hole is opened inside the sealing gasket;

[0032] Diverter pipes distributed in a circular array are welded inside the windshield. The diverter pipes are arranged at an inclined angle. The diverter pipes are distributed outside the conical wind collecting cover. The diverter pipes and the ventilation holes are distributed in a staggered manner.

[0033] By adopting the above technical solution, the sealing gasket fills the gap between the spoiler and the wind shield to prevent air leakage, while the holes and vents ensure the efficiency of air passage. The staggered distribution can make the holes correspond to the vents only after the spoiler rotates, ensuring controlled exhaust inside the diverter plate and achieving precise control of the air flow trajectory. The inclination angle of the diverter pipe can control the direction of air discharge, so that the gas discharged from the diverter pipe impacts the air flow discharged from the air supply pipe, breaking up the air flow trajectory and forming turbulence, which can enhance the mixing effect of air and fuel.

[0034] Specifically, the outer walls on both sides of the driving rod are provided with guide grooves, and one side of the guide groove is designed in a spiral shape;

[0035] By adopting the above technical solution, guide rods are installed on the outer walls on both sides of the spoiler. The shape of the outer wall of the guide rod away from the spoiler is adapted to the shape of the inner wall of the guide groove, and the end of the guide rod is slidably installed inside the guide groove.

[0036] When the driving rod moves horizontally, the spiral guide groove drives the baffle to rotate axially through the guide rod, thereby adjusting the position of the ventilation hole. It can adjust the relative position of the ventilation hole and the diverter pipe, change the opening of the diverter pipe, and meet the subsequent dynamic airflow adjustment.

[0037] Beneficial effects of the present invention:

[0038] (1) The high-performance boiler burner described in the present invention provides a high-velocity and high-pressure airflow to the fuel ignition position at the initial stage of fuel combustion inside the burner, which helps to increase the combustion-supporting air volume required for combustion, optimize the combustion efficiency, and meet the rapid temperature increase inside the boiler at the initial stage of combustion.

[0039] (2) In the high-performance boiler burner described in the present invention, the temperature inside the air gun fire tube heats and vaporizes the liquid inside the piston tube, and drives the piston plate and the piston rod to move horizontally, providing power for the subsequent dynamic adjustment of the airflow.

[0040] (3) The high-performance boiler burner described in the present invention has conical air collecting hoods that can unfold with each other, so that the flow trajectory of the air flow inside the air supply pipe is expanded, and the guide plate and the diverter plate disperse the flow direction of the air flow, so that the air flow forms a multi-angle dispersed air outlet, ensuring sufficient contact and mixing of air and fuel in a larger range, ensuring the uniformity and sufficiency of fuel combustion, and ensuring the stability and accuracy of the combustion temperature, so that it can adapt to different combustion conditions.

[0041] (4) In the high-performance boiler burner described in the present invention, the inclination angle of the diverter pipe causes the airflow to impact the airflow discharged from the inside of the air supply pipe, thereby reducing the impact intensity of the airflow, causing the fine airflow to disturb the large-flow airflow inside the air supply pipe, thereby achieving a stronger turbulent mixing effect between the subsequent air and fuel, further improving the mixing uniformity of the air and fuel, and further improving the combustion completeness of the fuel.

[0055] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0056] In order to save manpower and improve efficiency, as an embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 As shown, the high-performance boiler burner of the present invention includes a combustion mechanism, an air gathering mechanism, a driving mechanism, a flow guiding mechanism and a dispersing mechanism;

[0057] The wind gathering mechanism is composed of a wind shield 2 and a plurality of conical wind gathering covers 23. The plurality of conical wind gathering covers 23 are distributed in a circular array on the leeward side of the wind shield 2.

[0058] The driving mechanism is composed of two piston tubes 3 and two piston rods 33. The two piston tubes 3 are distributed on both sides of the windshield 2, and the piston rods 33 are movably installed inside the piston tubes 3.

[0059] The flow guide mechanism is composed of a driving rod 4 and a plurality of diverter plates 42. The center of the driving rod 4 and the center of the windshield 2 are in the same horizontal plane.

[0060] The dispersion mechanism is composed of a spoiler 5 and a plurality of ventilation holes 51 . The spoiler 5 is located on the windward side of the wind shield 2 . The plurality of ventilation holes 51 are arranged in a circular array inside the spoiler 5 .

[0061] When in use, the wind shield 2 blocks the air flow trajectory inside the shell 1 and can guide the air through the conical ventilation channel formed by the convergence of multiple conical wind hoods 23, ensuring that when the fuel is initially burned inside the burner, a high flow rate and high pressure airflow is provided to the fuel ignition position, which helps to increase the combustion-supporting air volume required for combustion, optimize the combustion efficiency, and meet the rapid temperature increase inside the boiler at the initial stage of combustion. As the fuel inside the air gun fire tube 13 continues to burn, the temperature provided to the inside of the boiler meets the requirement and tends to stabilize. The temperature inside the air gun fire tube 13 will heat and vaporize the liquid inside the piston tube 3, and drive the piston plate 34 and the piston rod 33 to move horizontally, providing power for subsequent dynamic adjustment of the air flow, thereby carrying the connecting rod 36 and the driving rod 4 to move synchronously until the guide plate 41 and the diverter plate 42 enter the air supply pipe 21. During the movement, the driving rod 4 pushes the conical wind hood 23 to rotate around the hinge 22 through the sleeve 25 and the linkage rod 26 until the conical wind hood 23 unfolds to make the air supply pipe 21, and the flow trajectory of the air flow inside is expanded, and the guide plate 41 and the diverter plate 42 disperse the flow direction of the air flow, so that the air flow forms a multi-angle dispersed wind, ensuring that the air and fuel are fully contacted and mixed in a larger range, ensuring the uniformity and sufficiency of fuel combustion, and ensuring the stability and accuracy of the combustion temperature, so as to adapt to different combustion conditions. When the drive rod 4 moves, the spiral shape of the guide groove 43 can cooperate with the guide rod 53 to drive the baffle 5 to rotate in a circle inside the limit block 27 until the ventilation hole 51 overlaps with the position of the diverter pipe 24, so that the airflow on the windward side of the wind shield 2 is dispersed through the diverter pipe 24 to achieve multi-point wind outlet, and due to the inclination angle of the diverter pipe 24, the airflow impacts the airflow discharged from the inside of the air supply pipe 21, thereby reducing the airflow impact intensity, and causing the fine airflow to disturb the large flow airflow inside the air supply pipe 21, thereby achieving a stronger turbulent mixing effect between the subsequent air and fuel, further improving the mixing uniformity of the air and fuel, and further improving the combustion sufficiency of the fuel.

[0062] For air intake, for example, Figure 1 As shown, the combustion mechanism consists of a shell 1 and an air gun fire tube 13. The outer wall of the shell 1 is welded with an air inlet cover 11, which is connected to the inside of the shell 1. The outer side of the air inlet cover 11 is screwed with an air inlet grille that is useful for filtering foreign matter.

[0063] An access plate 14 is screwed to one side of the outer wall of the upper end of the shell 1 , and an access hole adapted to the size of the access plate 14 is opened on the outer wall of the upper end of the shell 1 , and the position of the access plate 14 corresponds to that of the windshield 2 .

[0064] When in use, the fan impeller used inside the shell 1 can be driven to rotate by the external fan motor, thereby introducing outside air through the air inlet cover 11 until the air flows into the air gun fire tube 13 through the outer shell and the wind shield 2 to mix with the fuel. The air inlet grille can filter foreign matter in the air and prevent impurities from entering the combustion chamber. The inspection plate 14 and the inspection hole make it convenient for the staff to disassemble the inspection plate 14 and then inspect and maintain the wind gathering mechanism, driving mechanism, guide mechanism and dispersion mechanism.

[0065] For ignition, for example, Figure 2 As shown, the air gun fire tube 13 is screwed to the outer wall of the housing 1, and the air gun fire tube 13 is connected to the interior of the housing 1;

[0066] An igniter 15 is provided on one side of the inner wall of the air gun fire tube 13 , and an oil delivery pipe 12 is provided on one side of the outer wall of the shell 1 . The end of the oil delivery pipe 12 penetrates into the air gun fire tube 13 , and the end of the oil delivery pipe 12 corresponds to the position of the igniter 15 .

[0067] When in use, the matching oil pump provides a pair of oil pipes 12 to transport fuel to the inside of the burner, and the matching nozzle used at the end of the oil pipe 12 sprays the fuel, and cooperates with the igniter 15 to accurately control the timing of fuel injection and ignition, ensuring that the fuel and air are quickly ignited after mixing, thereby improving the ignition success rate and combustion efficiency.

[0068] In order to adjust the air supply state, for example, Figure 8 As shown, an air supply pipe 21 is welded inside the windshield 2, and a hinge 22 is provided on the outer wall of the air supply pipe 21 away from the windshield 2. The other end of the hinge 22 is connected to the outer wall of the conical wind collecting cover 23. The conical wind collecting cover 23 is rotatably connected to the air supply pipe 21 through the hinge 22.

[0069] The inner wall of the conical wind collecting cover 23 and the outer wall of the driving rod 4 are both installed with a clamping sleeve 25. The clamping sleeve 25 is distributed in a circular array on the outer wall of the driving rod 4. The internal pin shaft of the clamping sleeve 25 is connected to the linkage rod 26 for driving the rotation. The conical wind collecting cover 23 is connected to the driving rod 4 through the clamping sleeve 25 and the linkage rod 26.

[0070] When in use, the wind shield 2 is welded to the inner wall of the shell 1 to ensure that the wind shield 2 is stably located in the shell 1. The conical wind collecting hood 23 is rotatably connected to the air supply pipe 21 through a hinge 22, and is connected to the sleeve 25 of the linkage rod 26 and the drive rod 4. The movement of the drive rod 4 can drive the angle of the conical wind collecting hood 23 to be adjusted, dynamically changing the wind collecting direction and the degree of airflow convergence to adapt to combustion requirements under different loads.

[0071] To drive the movement, for example, Figure 7As shown, a heat insulation pad 32 for reducing the temperature transfer efficiency is bonded and fixed to the outer wall of the piston tube 3, and the heat insulation pad 32 is located on the leeward side of the windshield 2;

[0072] Connectors 31 are installed on both sides of the outer wall of the upper end of the piston tube 3, and the piston tube 3 is screwed to the leeward side of the windshield 2 through the connectors 31;

[0073] The outer wall of one end of the piston rod 33 is screwed to the piston plate 34, and a sealing ring 35 is bonded and fixed to the outer wall of the piston plate 34 and one side of the inner wall of the piston tube 3. The gap between the piston plate 34 and the piston tube 3 is filled by the sealing ring 35, and the gap between the piston rod 33 and the piston tube 3 is filled by the sealing ring 35;

[0074] The end of the piston rod 33 away from the piston plate 34 is screwed to a connecting rod 36 , and the connecting rod 36 is screwed to the driving rod 4 .

[0075] When in use, the thermal insulation pad 32 reduces the temperature transfer of the piston tube 3 and the heat vaporization rate of the liquid inside the piston tube 3, thereby ensuring that when the connecting rod 36 moves, the temperature inside the boiler has been heated to the required temperature, thereby achieving the purpose of controlling the movement time of the drive rod 4. The liquid inside the piston tube 3 exists between the two sealing rings 35, so that after the liquid is heated and vaporized and expanded, it will push the piston plate 34 to move horizontally inside the piston tube 3. The sealing ring 35 blocks the liquid to ensure the sealing during the liquid vaporization process. After the device is not in use, the vaporized liquid condenses, and due to the incompressibility of the liquid, it will pull the piston plate 34 to reset inside the piston rod 33. The piston rod 33 is fixed to the linkage rod 26 by the connecting rod 36, and the linear motion of the piston is converted into the swing of the linkage rod 26, which can drive the conical wind gathering hood 23 or the baffle 5 to move.

[0076] For example, in order to guide the flow, Figure 9 As shown, a guide plate 41 for dispersing the airflow is welded to the outer wall of one side of the driving rod 4, and the outer wall of the guide plate 41 is designed in an inclined shape;

[0077] A plurality of diverter plates 42 are welded to the outer wall of the guide plate 41 in a circular array state, and the plurality of diverter plates 42 are used to separate the air supply areas.

[0078] When in use, the inclined design of the guide plate 41 can guide the airflow in a specific direction to reduce airflow resistance. The circular array of diverter plates 42 divides the airflow into multiple branches, further refining the airflow distribution, making the air and fuel mix more fully and ensuring complete combustion.

[0079] In order to limit the rotation position, for example, Figure 5As shown, a circular array of limit blocks 27 are provided on the outside of the spoiler 5. The limit blocks 27 are designed in an L-shape and are screwed to the windward side of the wind shield 2. The spoiler 5 is away from the limit blocks 27 to limit the rotation position.

[0080] When in use, the multi-point limit blocks 27 can limit the position of the spoiler 5 and ensure that the position of the spoiler 5 is relatively stable when it is driven to rotate, thereby ensuring that the spoiler 5 works stably in the set position.

[0081] To disperse the air, for example, Figure 8 As shown, a sealing gasket 52 for providing sealing is bonded and fixed to the outer wall of the spoiler 5. The other side of the sealing gasket 52 contacts the windward side of the wind deflector 2. A hole adapted to the ventilation hole 51 is opened inside the sealing gasket 52.

[0082] A circular array of diverter pipes 24 is welded inside the windshield 2 . The diverter pipes 24 are arranged at an inclined angle and are distributed outside the conical wind collecting cover 23 . The diverter pipes 24 and the ventilation holes 51 are staggered.

[0083] When in use, the sealing gasket 52 fills the gap between the spoiler 5 and the wind shield 2 to prevent air leakage, while the holes and vents 51 ensure the air passage efficiency. The staggered distribution can make the holes correspond to the vents 51 only after the spoiler 5 rotates, ensuring controlled exhaust inside the diverter plate 42 and achieving precise control of the air flow trajectory. The inclination angle of the diverter pipe 24 can control the air flow discharge direction, so that the gas discharged from the diverter pipe 24 impacts the air flow discharged from the air supply pipe 21, breaking up the air flow trajectory and forming turbulence, which can enhance the mixing effect of air and fuel.

[0084] To drive the rotation, for example, Figure 9 As shown, guide grooves 43 are provided on both sides of the outer wall of the driving rod 4, and one side of the guide groove 43 is designed in a spiral shape;

[0085] Guide rods 53 are installed on the outer walls of both sides of the spoiler 5. The shape of the outer wall of the guide rod 53 away from the spoiler 5 is adapted to the shape of the inner wall of the guide groove 43, and the end of the guide rod 53 is slidably installed inside the guide groove 43.

[0086] During use, when the driving rod 4 moves horizontally, the spiral guide groove 43 drives the baffle 5 to rotate axially through the guide rod 53, thereby adjusting the position of the ventilation hole 51. The relative position of the ventilation hole 51 and the diverter pipe 24 can be adjusted, and the opening of the diverter pipe 24 can be changed to meet the subsequent dynamic airflow adjustment.

[0087] When the present invention is in use, the external fan motor drives the fan impeller inside the housing 1 to rotate, and the outside air is introduced through the air inlet cover 11. The air inlet grille filters foreign matter in the air to prevent impurities from entering the combustion chamber. The air flows through the interior of the housing 1 to the wind shield 2. At the same time, the oil pump delivers fuel to the air gun fire tube 13 through the oil pipeline 12. The nozzle at the end of the oil pipeline 12 sprays the fuel near the igniter 15. The igniter 15 generates an electric spark, ignites the mixture of fuel and air, and combustion begins. At this time, the wind shield 2 blocks the air flow trajectory, and the conical wind collecting cover 23 distributed in a circular array on its leeward side gathers the air flow to form a conical ventilation channel, which delivers high-flow rate and high-pressure combustion-supporting air to the fuel ignition position, quickly raising the internal temperature of the boiler to meet the temperature increase requirements in the early stage of combustion;

[0088] As the fuel in the air gun fire tube 13 continues to burn, the internal temperature of the boiler reaches the required level and tends to be stable. At this time, the internal temperature of the air gun fire tube 13 heats the outer wall of the piston tube 3. The liquid in the piston tube 3 vaporizes and expands due to the heat, pushing the piston plate 34 to move horizontally in the piston tube 3. The movement of the piston plate 34 drives the piston rod 33 to retract into the piston tube 3. The heat insulation pad 32 on the outer wall of the piston tube 3 reduces the temperature transfer efficiency, avoids premature vaporization of the liquid, and ensures that the drive rod 4 starts to move only after the boiler temperature reaches a stable value, thereby achieving precise control of the adjustment timing;

[0089] The connecting rod 36 at the end of the piston rod 33 pulls the drive rod 4, which in turn moves toward the air supply duct 21 through the ferrule 25. As the drive rod 4 moves, the linkage rod 26 pushes the conical air collector 23 to rotate about the hinge 22, causing the conical air collector 23, which originally gathered the airflow, to expand and expand the airflow trajectory within the air supply duct 21. Simultaneously, the guide plates 41 on the drive rod 4 and the circular array of diverter plates 42 enter the interior of the air supply duct 21. The inclined guide plates 41 guide the airflow, while the diverter plates 42 separate the airflow into multiple branches, achieving multi-angle air distribution.

[0090] As the drive rod 4 moves, the spiral guide grooves 43 on either side of the drive rod 4 drive the spoiler 5 to rotate circumferentially within the stopper 27 via the guide rods 53. When the spoiler 5 rotates until the ventilation holes 51 overlap the diverter tube 24, the airflow on the windward side of the wind deflector 2 is dispersed and discharged at multiple points through the diverter tube 24. The diverter tube 24 is arranged at an angle, and the discharged airflow impacts the high-flow airflow within the air supply tube 21, reducing the impact strength and creating disturbances, promoting more turbulent mixing of air and fuel.
