[0031] In one embodiment of this utility model, such as Figure 1-5 As shown, a fuel line heating device for a burner is provided, including a combustion chamber 10, a fuel line 20, and an insulation sleeve 30. An ignition mechanism 11 for fuel ignition is provided on one side of the combustion chamber 10. The fuel line 20 includes an inlet section 21, a heat exchange section 22, and an outlet section 23. The heat exchange section 22 is arranged around the outside of the combustion chamber 10. One end of the heat exchange section 22 is connected to the inlet section 21, and the other end is connected to the outlet section 23. The outlet end of the outlet section 23 is located at the outlet end of the combustion chamber 10. The insulation sleeve 30 is located on the outside and is tightly connected to the fuel line 20 to reduce heat loss from the combustion chamber 10.
[0032] By setting up an oil inlet section 21, a heat exchange section 22, and an oil outlet section 23, fuel flows from the oil inlet section 21 into the heat exchange section 22. Through the heat exchange section 22, heat is exchanged with the heat inside the combustion chamber 10, preheating the fuel inside the heat exchange section 22. This allows the fuel to mix more easily with the air after being sprayed out from the oil outlet section 23, thereby improving the fuel atomization effect and promoting more complete combustion. At the same time, by setting up an insulation jacket 30, heat loss from the combustion chamber 10 is further reduced, ensuring that the fuel in the fuel pipe 20 can continuously and stably absorb heat during the heat exchange process.
[0033] Preferably, the oil inlet section 21 is located outside the insulation sleeve 30. The end of the oil inlet section 21 passes through the insulation sleeve 30 and connects to the beginning of the heat exchange section 22. The heat exchange section 22 is wound around the outside of the combustion cylinder 10 at equal intervals. The oil outlet section 23 is located outside the output end of the combustion cylinder 10, and the end of the oil outlet section 23 connects to the end of the heat exchange section 22. Both the oil inlet section 21 and the oil outlet section 23 extend in the left-right direction. By arranging the heat exchange section 22 at equal intervals, the heat generated by the combustion cylinder 10 can be fully utilized to preheat the fuel in the heat exchange section 22. The preheated fuel has a higher temperature and is easier to mix with air, forming a good atomization effect, thereby promoting the complete combustion of the fuel.
[0034] Specifically, the oil outlet section 23 includes a first connecting portion 231a and a first bending portion 232a. The first connecting portion 231a is located outside the output end of the combustion cylinder 10 and is connected to the end of the heat exchange section 22. The first bending portion 232a is connected to the end of the first connecting portion 231a, and the end of the first bending portion 232a is located in the center of the combustion cylinder 10. By placing the end of the first bending portion 232a in the center of the combustion cylinder 10, the injected fuel can be evenly distributed within the combustion cylinder 10, better mixed with air, forming a good atomization effect, thereby promoting complete combustion of the fuel.
[0035] Preferably, the oil inlet section 21 is located outside the insulation sleeve 30. The end of the oil inlet section 21 passes through the insulation sleeve 30 and extends to the outside of the output end of the combustion cylinder 10, connecting with the beginning of the heat exchange section 22. The heat exchange section 22 is evenly spaced around the outside of the combustion cylinder 10. The oil outlet section 23 is located inside the combustion cylinder 10, with its beginning passing through the combustion cylinder 10 and connecting with the end of the heat exchange section 22. Both the oil inlet section 21 and the oil outlet section 23 extend in the left-right direction. By arranging the heat exchange section 22 evenly spaced, the heat generated by the combustion cylinder 10 can be fully utilized to preheat the fuel in the heat exchange section 22. The preheated fuel has a higher temperature, making it easier to mix with air and form a good atomization effect, thereby promoting complete combustion of the fuel.
[0036] Specifically, the oil outlet section 23 includes a second connecting portion 231b and a second bending portion 232b. The second connecting portion 231b is located inside the combustion cylinder 10 and is connected to the end of the heat exchange section 22. The second bending portion 232b is connected to the end of the second connecting portion 231b, and the end of the second bending portion 232b is located in the center of the combustion cylinder 10. By placing the end of the second bending portion 232b in the center of the combustion cylinder 10, the injected fuel can be evenly distributed within the combustion cylinder 10, better mixed with air, forming a good atomization effect, thereby promoting complete combustion of the fuel.
[0037] Preferably, the oil inlet section 21 is located outside the insulation sleeve 30. The end of the oil inlet section 21 passes through the insulation sleeve 30 and extends to the outside of the output end of the combustion chamber 10, connecting with the beginning of the heat exchange section 22. The heat exchange section 22 includes multiple sets of U-shaped portions 22a, which are evenly distributed on the outside of the combustion chamber 10, with adjacent U-shaped portions 22a connected end-to-end. The oil outlet section 23 is located outside the output end of the combustion chamber 10 and is positioned opposite to the oil inlet section 21. The beginning of the oil outlet section 23 connects to the end of the heat exchange section 22. Both the oil inlet section 21 and the oil outlet section 23 extend in a left-right direction. By designing the heat exchange section 22 with multiple sets of U-shaped portions 22a evenly spaced, the contact area between the heat exchange section 22 and the combustion cylinder 10 is increased. This allows the heat generated by the combustion cylinder 10 to be fully utilized to preheat the fuel in the heat exchange section 22. The preheated fuel has a higher temperature and is easier to mix with air, forming a good atomization effect, thereby promoting the complete combustion of the fuel.
[0038] Specifically, the oil outlet section 23 includes a third connecting portion 231c and a third bending portion 232c. The third connecting portion 231c is located outside the output end of the combustion cylinder 10 and is connected to the end of the heat exchange section 22. The third bending portion 232c is connected to the end of the third connecting portion 231c, and the end of the third bending portion 232c is located in the center of the combustion cylinder 10. By placing the end of the third bending portion 232c in the center of the combustion cylinder 10, the injected fuel can be evenly distributed within the combustion cylinder 10, better mixed with air, forming a good atomization effect, thereby promoting complete combustion of the fuel.
[0039] Preferably, a nozzle 24 is connected to the end of the oil outlet section 23. The bottom of the nozzle 24 is provided with multiple sets of circumferentially distributed nozzles. By setting multiple sets of nozzles, the atomization effect of the fuel spray is improved, so that the fuel is more evenly distributed in the air, thereby improving the fuel combustion efficiency.
[0040] Furthermore, the fuel inlet section 21 is equipped with a fuel inlet nozzle 25. The fuel inlet nozzle 25 is connected to an external fuel tank to facilitate the transfer of fuel to the combustion chamber 10.
[0041] Preferably, multiple sets of circumferentially distributed positioning blocks 31 are provided between the insulation jacket 30 and the fuel pipe 20. The positioning blocks 31 have an arc-shaped structure and are tightly connected to the fuel pipe 20. By setting multiple sets of positioning blocks 31, a tight connection between the fuel pipe and the insulation jacket 30 is ensured, preventing the insulation jacket 30 from shaking during combustion and reducing heat loss from the combustion chamber 10.
[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
