Description

Technical Field

[0001] This invention relates to the field of combustion engine technology, and specifically to a methanol gasification combustion engine. Background Technology

[0002] Currently, common methanol burners typically employ atomization combustion or direct gasification combustion. In existing technologies, the coordination between the fuel supply system, gasification structure, and combustion chamber is not yet perfect, resulting in insufficient mixing and stable combustion of methanol within the combustion chamber. While some devices attempt to improve combustion by adjusting nozzle structure or adding preheating stages, issues such as insufficient mixing uniformity, localized low temperatures, or unreasonable airflow organization still exist during actual operation, affecting the continuity and integrity of combustion. Summary of the Invention

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0020] According to an embodiment of the present invention, a methanol gasification burner is provided, comprising a housing assembly, a first connector 2, a second connector 4, a gas pipe 6, and a fuel pipe 7. The housing assembly has a combustion chamber 1. The first connector 2 is provided with a first cavity 3 and is disposed within the combustion chamber 1. The second connector 4 is provided with a second cavity 5 and is located within the first cavity 3. The gas pipe 6 includes an inlet end and an outlet end. The inlet end of the gas pipe 6 communicates with the first cavity 3, and the outlet end of the gas pipe 6 communicates with the combustion chamber 1, adapted to supply air into the combustion chamber 1. The fuel pipe 7 is located within the gas pipe 6, and a gap is left between the outer wall of the fuel pipe 7 and the inner wall of the gas pipe 6. The fuel pipe 7 has a feed end and a discharge end. The feed end of the fuel pipe 7 communicates with the second cavity 5, and the discharge end of the fuel pipe 7 communicates with the combustion chamber 1, adapted to supply fuel into the combustion chamber 1. Among them, the outer wall of the gas pipe 6 is provided with a gas hole 8, which connects the gap and the combustion chamber 1, and the fuel pipe 7 is provided with a feed hole 9, which connects the inner cavity of the fuel pipe 7 and the gap.

[0021] In this embodiment, a unique fuel-air premixing channel is created by placing the fuel pipe 7 inside the air pipe 6 and maintaining a gap. Fuel is injected into the gap through the feed hole 9 on the fuel pipe 7, where it collides and mixes with the air flowing through the air pipe 6 in the confined space for the first time. Subsequently, they enter the combustion chamber 1 together through the air hole 8 on the air pipe 6. This in-pipe premixing structure enhances the mixing effect of fuel and air, improves the uniformity of the mixed gas from the source, and lays a solid foundation for subsequent stable and complete combustion. This effectively overcomes the problems of incomplete combustion, low thermal efficiency, and emission pollution caused by uneven mixing in the prior art.

[0022] In one embodiment, the housing assembly includes a first cylindrical body 10, a second cylindrical body 11, a third cylindrical body 12, and a partition 13. The partition 13 is disposed within the first cylindrical body 10, dividing the inner cavity of the first cylindrical body 10 into an upper chamber and a lower chamber 14. The second cylindrical body 11 and the third cylindrical body 12, which are nested together, are both disposed in the upper chamber, with the second cylindrical body 11 located between the first cylindrical body 10 and the third cylindrical body 12. The inner cavity of the first cylindrical body 10 is a combustion chamber 1.

[0023] In this embodiment, a multi-layer shell structure is formed by setting a second cylinder 11 and a third cylinder 12 that are nested together with the first cylinder 10. This structure not only provides stable support for the combustion chamber 1, but more importantly, the interlayer between the cylinders can form an effective heat insulation zone or airflow channel, which can reduce heat loss from the combustion chamber 1, improve thermal efficiency, and at the same time help to preheat the air entering the burner, thus optimizing the thermal management of the entire system.

[0024] In one embodiment, the system further includes a fan 15, the output end of which passes through the first cylinder 10 and communicates with the lower chamber 14. The first connector 2 is connected to the partition 13. The partition 13 has a first connecting hole 16 at its center. The first connecting hole 16 passes through the partition 13 and the first connector 2 in sequence, and the first connecting hole 16 communicates with the first cavity 3 and the lower chamber 14.

[0025] In this embodiment, by connecting the output end of the blower 15 to the lower chamber 14, and using the first connection hole 16 on the partition 13 to connect the lower chamber 14 to the first cavity 3 of the first connector 2, a clear and smooth combustion air delivery path is constructed. After the air is output from the blower 15, it flows sequentially through the lower chamber 14, the first connection hole 16, and the first cavity 3, and is finally distributed to each air pipe 6. This integrated design ensures the stability and concentration of the air supply, while making the structure compact and reducing complex external pipeline connections.

[0026] In one embodiment, a flame guide 17 is also included, one end of which is connected to the combustion chamber 1, and the other end of the flame guide 17 passes through the third cylinder 12, the second cylinder 11 and the first cylinder 10 in sequence, and extends out from the first cylinder 10.

[0027] In this embodiment, the flame conduit 17 is designed to provide a directional channel for the high-temperature flame generated by combustion, enabling it to be safely and controllably directed to a specific heat utilization device. The conduit sequentially penetrates the internal cylindrical structure and extends out of the first cylindrical body 10, ensuring effective isolation between the flame output path and the internal structure of the burner, thus improving the safety and convenience of equipment integration.

[0028] In one embodiment, a sleeve 18 is further included, which is fitted over the outside of the flame guide tube 17. An air outlet channel 19 is formed between the inner wall of the sleeve 18 and the outer wall of the flame guide tube 17. A connecting rib 20 is provided in the air outlet channel 19, which connects the sleeve 18 and the flame guide tube 17 respectively. The extending direction of the connecting rib 20 is parallel to the axial direction of the flame guide tube 17. An insulation layer is provided between the first cylinder 10 and the second cylinder 11. An air duct interlayer 21 is formed between the second cylinder 11 and the third cylinder 12. A plurality of second connecting holes 22 are provided on the top surface of the partition 13. The second connecting holes 22 connect the air duct interlayer 21 and the lower chamber 14. The sleeve 18 penetrates the first cylinder 10 and the second cylinder 11, and the air outlet channel 19 communicates with the air duct interlayer 21.

[0029] In this embodiment, a sleeve 18 is provided on the outside of the flame duct 17 to form an air outlet channel 19, which is connected to the air duct interlayer 21 formed between the second cylinder 11 and the third cylinder 12. This design allows a portion of the cooling air from the fan 15 to flow through the air duct interlayer 21 and the air outlet channel 19, thereby forming a continuous air-cooled protective sleeve around the flame duct 17. This effectively removes the radiant heat from the flame duct 17, preventing it from being damaged due to overheating, and significantly improving the durability and reliability of key components. The connecting rib 20 ensures the smooth passage of cooling airflow while maintaining structural connection.

[0030] In one embodiment, the system further includes a fuel pump 23, a monitoring tube 24, and an igniter 26. The output of the fuel pump 23 is connected to a first pipe and a second pipe. The monitoring tube 24 includes a first end and a second end opposite to each other. The first end of the monitoring tube 24 passes sequentially through a first cylinder 10, a second cylinder 11, and a third cylinder 12, communicating with the combustion chamber 1. The second end of the monitoring tube 24 is provided with a sight glass 25. The igniter 26 is disposed on the monitoring tube 24, with its ignition end located inside the monitoring tube 24.

[0031] The first pipe is connected to the inner cavity of the monitoring pipe 24, and the second pipe passes through the first cylinder 10, the second cylinder 11, the third cylinder 12 and the second connector 4 in sequence, and is connected to the second cavity 5.

[0032] In this embodiment, the monitoring tube 24, igniter 26, and fuel supply pipeline are highly integrated. The monitoring tube 24 extends directly into the combustion chamber 1, and its end sight glass 25 allows operators to directly observe the ignition and combustion status, achieving visual monitoring. The igniter 26 is directly mounted on the monitoring tube 24, ensuring its ignition end is in the optimal ignition position, thus improving the ignition success rate. Fuel is directly injected into the monitoring tube 24 through the first pipeline, ensuring a concentrated fuel supply during the initial ignition stage. The second cavity 5, connected to the second pipeline, is responsible for the fuel supply during the main combustion stage. This branched design makes fuel control during ignition and the main combustion stage more precise and reliable.

[0033] In one embodiment, the monitoring tube 24 is also equipped with a photoelectric sensor 27.

[0034] In this embodiment, by installing a photoelectric sensor 27 (flame detector) on the monitoring tube 24, it is possible to monitor in real time whether a stable flame exists in the combustion chamber 1. Once flameout or ignition failure is detected, the photoelectric sensor 27 can quickly send a signal to the control system, thereby cutting off the fuel supply in time, preventing unburned fuel from accumulating and causing safety accidents, and enhancing the operational safety and automation level of the burner.

[0035] In one embodiment, along the direction from the fuel pump 23 to the monitoring pipe 24, a first solenoid valve 28 and a first heating element 29 are sequentially arranged on the first pipe, and a second solenoid valve 30, a second heating element 31 and a catalyst 32 are sequentially arranged on the second pipe.

[0036] In this embodiment, solenoid valves and heating elements are respectively installed on the first and second pipelines, and a catalyst 32 is specifically added to the second pipeline. The solenoid valves enable independent and precise on / off control of the two fuel passages. The heating elements ensure that the fuel is fully vaporized before entering the combustion chamber 1, improving combustion conditions. The introduction of the catalyst 32 can promote partial pre-reaction or cracking of fuel molecules before entering the combustion chamber 1, generating smaller molecules that are easier to burn completely, thereby further improving combustion efficiency and reducing harmful emissions at the chemical level.

[0037] In one embodiment, multiple gas pipes 6 are provided, and the multiple gas pipes 6 are distributed sequentially along the circumference of the combustion chamber 1. Multiple fuel pipes 7 are provided, and the multiple fuel pipes 7 are respectively arranged in one-to-one correspondence with the multiple gas pipes 6. Both the fuel pipes 7 and the gas pipes 6 are configured as arc-shaped structures.

[0038] In this embodiment, by arranging multiple fuel pipes 7 and air pipes 6 in an arc-shaped structure distributed sequentially along the circumference of the combustion chamber 1, uniform and three-dimensional injection of fuel and air in the circumferential direction of the combustion chamber 1 is achieved. This layout is beneficial for forming a stable and symmetrical flow field and temperature field within the combustion chamber 1, avoiding localized high temperatures or combustion dead zones, and ensuring that the fuel can be fully mixed with air and completely burned throughout the entire combustion space. This improves efficiency while effectively reducing the generation of pollutants such as nitrogen oxides.

[0039] In one embodiment, multiple air holes 8 are spaced apart along the extension direction of the air pipe 6, and multiple feed holes 9 are spaced apart along the extension direction of the fuel pipe 7, with both air holes 8 and feed holes 9 facing the partition plate 13.

[0040] In this embodiment, by setting multiple air holes 8 and feed holes 9 and distributing them at intervals along the pipe body, while ensuring that their outlet directions are all towards the baffle 13, a multi-stream, dispersed injection state is achieved when fuel and air leave the pipe. This multi-hole directional injection structure not only further enhances the mixing effect, but also ensures that all jets are directed towards the high-temperature region at the center of the combustion chamber 1, which helps to form a strong airflow vortex, prolongs the residence time of fuel in the combustion chamber 1, and ensures more complete, intense, and stable combustion.

[0041] In one embodiment, by alternately opening and closing the first solenoid valve 28 and the second solenoid valve 30, the continuous fuel supply is cleverly transformed into two independent, intermittent pulse supply paths. One path (usually via the first conduit and monitoring pipe 24) is responsible for providing concentrated and controllable fuel during the initial ignition stage or when maintaining a small flame, ensuring ignition success rate and the stability of the small flame; the other path (usually via the second conduit to the main combustion zone) is responsible for supplying most of the fuel during the main combustion stage. This "staggered" pulse supply method generates continuous airflow disturbance within the combustion chamber 1, greatly enhancing the fuel-air mixing process and avoiding the mixing inertia that may result from continuous stable flow, thereby promoting complete fuel vaporization and combustion, improving combustion efficiency, and suppressing the formation of harmful substances. At the same time, from a system protection perspective, the pulse operation mode can effectively prevent any single conduit (especially the monitoring pipe 24 and its nozzle directly exposed to the high-temperature combustion zone) from fuel coking or carbonization blockage due to prolonged heating, improving the reliability and durability of the system. Therefore, this design, based on a single continuous feeding hardware, achieves precise ignition control, optimized mixing and combustion effects, and long-term protection of key components through sophisticated control logic.
