[0001] This application relates to the field of burner technology, specifically to an atomization-to-full gasification furnace burner. Background Technology

[0002] A burner is a general term for a device that sprays fuel and air in a specific manner to mix and burn. Burners are classified into several types according to their application: industrial burners, combustion engines, civil burners, and special burners.

[0003] Traditional burners mostly employ atomization combustion and full gasification combustion methods. Atomization combustion involves atomizing liquid fuel into fine droplets before combustion. This method suffers from low combustion efficiency and high pollutant emissions. Full gasification combustion technology can completely gasify liquid fuel, achieving efficient and clean combustion. However, existing full gasification burners are complex in structure and expensive. Full gasification burners also have high requirements for fuel viscosity and composition, making it difficult to adapt to different types of liquid fuels and hindering their widespread application. Therefore, this application proposes an atomization-to-full gasification furnace burner. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0025] like Figures 1-6 As shown, one embodiment of this application discloses an atomization-to-full gasification furnace burner, comprising:

[0026] A combustion chamber 1, open at one end, includes a combustion chamber 101 and a mixing chamber 102 that are connected to each other. An annular shell 2 is coaxially disposed within the mixing chamber 102, which divides the mixing chamber 102 into a connected gasification chamber and a gas-mixing chamber. Preferably, as shown... Figure 2 As shown, the left side is the combustion chamber 101, and the right side is the mixing chamber 102. The left end of the annular shell 2 has a convex ring connected to the inner wall of the combustion cylinder 1. There is a gap between the right end of the annular shell 2 and the closed end of the combustion cylinder 1. An ignition device 3 is installed on the combustion cylinder 1, with the ignition head located inside the combustion chamber 101. A fuel pipe 4 is installed on the combustion cylinder 1, with one end located inside the gasification chamber and connected to an atomizing nozzle 5. Preferably, the other end of the fuel pipe 4 is connected to an external storage device. The external storage device transports liquid fuel through the fuel pipe 4 and atomizes it into fine droplets through the atomizing nozzle 5, which then enters the gasification chamber. A spiral tube 6 is installed on the inner wall of the combustion cylinder 1. Preferably, the spiral tube 6 is made of copper. One end of the spiral tube 6 is connected to a blower 8 through a first conveying pipe 7, and the other end of the spiral tube 6 is connected to an air blower 9 through a second conveying pipe 16. The air blower 9 is coaxially inserted inside the annular shell 2. During combustion... During operation, the blower 8 delivers outside air (oxygen) through the first delivery pipe 7 into the spiral tube 6. The air flows from the left end to the right end within the spiral tube 6, and then through the second delivery pipe 16 and the air nozzle 9 into the annular shell 2. While continuously delivering fuel, the atomized fuel flows to the right and into the annular shell 2 (when the air nozzle 9 continuously delivers air to the left, the atomized fuel can flow from the vaporization chamber to the right into the air-mixing chamber under the action of the airflow). After the atomized fuel and air mix, they flow into the combustion chamber 101. The ignition device 3 ignites the mixed fuel, thus ensuring complete combustion of the fuel-air mixture. The combustion flame is ejected from the left opening end of the combustion cylinder 1. During combustion, the flame in the combustion chamber 101 also heats the spiral tube 6. During continuous gas delivery, the spiral tube 6, heated by the flame, generates high temperatures, which are then transferred to the air being transported within it. Figure 2As shown, the right section of the spiral tube 6 is located inside the gasification chamber. When the fuel enters the gasification chamber after atomization, the atomized fuel will contact the surface of the spiral tube 6. The spiral tube 6 and the high-temperature gas flowing inside it will conduct heat to the atomized fuel, heating the fuel through high temperature, thereby gasifying the fuel. Under the action of the spiral tube 6 and the high-temperature gas inside it, the gasification chamber formed by the annular shell 2 and the inner wall of the combustion cylinder 1 has a certain high temperature, thereby improving the gasification efficiency. After the atomized fuel is gasified, it is fully mixed with air, thereby making the fuel fully combusted.

[0027] In this design, a spiral tube 6 is installed on the inner wall of the combustion cylinder 1, and an annular shell 2 is installed inside the combustion cylinder 1. The spiral tube 6 passes through the gasification chamber formed between the combustion cylinder 1 and the annular shell 2, and delivers the atomized fuel into the gasification chamber. External air (oxygen) for combustion is delivered from left to right through the spiral tube 6. The combustion flame heats the air and the spiral tube 6, and the heat is conducted to the gasification chamber and acts on the atomized fuel, thereby heating the fuel and causing it to gasify. After gasification, the fuel is mixed with air, thus ensuring complete combustion and improving practicality.

[0028] like Figure 2 and Figure 5 As shown, in some embodiments, one end of the fuel pipe 4 located in the gasification chamber is connected to the first annular pipe 10. The number of atomizing nozzles 5 is several and they are arranged in a ring array connected to the first annular pipe 10. Due to the spiral structure of the spiral pipe 6 and the annular cavity of the gasification chamber, by connecting the end of the fuel pipe 4 to the first annular pipe 10 and setting the atomizing nozzles 5 on the first annular pipe 10, the fuel is first delivered into the first annular pipe 10 and finally sprayed out through several atomizing nozzles 5, so that the fuel is sprayed out in a ring to the right, ensuring that the feed into the gasification chamber is uniform and making full use of the spiral pipe 6 for heating and heat exchange.

[0029] like Figure 1 and Figure 5 As shown, in some embodiments, the spiral tube 6 is connected to a branch tube 11, and its end extends into the vaporization chamber. Preferably, as shown... Figure 2 As shown, the connection end between the branch pipe 11 and the spiral pipe 6 is located inside the combustion chamber 101. When the airflow drawn in by the blower 8 flows along the spiral pipe 6, part of the airflow flows from the branch pipe 11 to the right into the gasification chamber. This not only allows for initial mixing with the fuel, but also applies a pneumatic thrust to the right, facilitating a smoother flow of fuel from the gasification chamber into the air-mixing chamber, thereby improving practicality.

[0030] like Figure 5As shown, in some embodiments, the end of the branch pipe 11 is connected to a second ring pipe 12, and a number of nozzles 13 arranged in a ring are connected to the second ring pipe 12. Through the second ring pipe 12 and the ring-arc nozzles 13, the airflow first flows into the second ring pipe 12, and then is delivered in a ring direction through the number of nozzles 13, so that the airflow is uniform, which not only improves the mixing effect, but also improves the aerodynamic pushing effect on the fuel.

[0031] like Figure 6 As shown, in some embodiments, the air blowing head 9 includes a first conical shell 901 connected to the second delivery pipe 16, and a second conical shell 902 connected to the first conical shell 901. Preferably, the first conical shell 901 facilitates the diffusion of air delivered by the second delivery pipe 16 into the air-mixing chamber. The larger opening end of the second conical shell 902 overlaps with the closed end of the combustion cylinder 1, which serves as a guide to facilitate the smoother flow of fuel in the gasification chamber into the air-mixing chamber for mixing with air.

[0032] like Figure 2 As shown, in some embodiments, a disturbance element 14 is provided inside the annular shell 2, which is used to disturb the mixed gas by means of the airflow ejected from the air nozzle 9. By providing the disturbance element 14, the gas flow ejected from the air nozzle 9 can make the fuel in the gasification chamber come into better contact with and mix with the air, resulting in a better mixing effect and more complete fuel combustion.

[0033] like Figure 4 As shown, in some embodiments, the disturbance element 14 includes a shaft 1401, which is coaxially rotatably mounted inside the annular shell 2 via a bracket. A swivel head 1402 is fixed on the shaft 1401. Preferably, the swivel head 1402 is constructed with a plurality of inclined blades. The airflow blown out by the air blown head 9 will impact the blades on the swivel head 1402, thereby causing the swivel head 1402 and the shaft 1401 to rotate. When the swivel head 1402 rotates, it disturbs the airflow, causing the airflow to swirl, thereby improving the contact and mixing effect of fuel and air.

[0034] like Figure 1 and Figure 2 As shown, in some embodiments, a spiral plate 15 is provided at one end of the spiral tube 6 located in the combustion chamber 101. Preferably, the spiral plate 15 is also made of copper plate. The spiral plate 15 is used to increase the contact area between the spiral tube 6 and the flame, thereby improving the heat exchange effect.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
