[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1 to 3This utility model provides a technical solution: a combustion device for methanol reforming to produce hydrogen, including a burner 1. A first fuel pipe 2 and a second fuel pipe 3 are installed on one side of the burner 1. A fuel chamber 6 and a mixing chamber 7 are opened inside the burner 1. The first fuel pipe 2 and the second fuel pipe 3 are both connected to the fuel chamber 6. A guide block 18 is installed between the fuel chamber 6 and the mixing chamber 7. An air supply ring 11 is installed on the burner 1, and the air supply ring 11 corresponds to the mixing chamber 7. A combustion pipe 9 is rotatably fitted on the burner 1, and the combustion pipe 9 corresponds to the guide block 18.

[0021] In this embodiment, a connecting cavity 8 is provided between the fuel chamber 6 and the mixing chamber 7. The connecting cavity 8 corresponds to the guide block 18. A sliding groove 17 is provided in the connecting cavity 8. A sliding rod 19 is fixed on the guide block 18. The sliding rod 19 corresponds to the sliding groove 17. Solenoid valves 4 are installed in both the first fuel pipe 2 and the second fuel pipe 3. A heating pipe 5 is installed on the periphery of the fuel chamber 6.

[0022] Specifically, liquid methanol can be fed into fuel chamber 6 through the first fuel pipe 2, and then the heating pipe 5 can be energized to vaporize the liquid methanol in fuel chamber 6, thus facilitating combustion.

[0023] The guide block 18 has a spindle-shaped structure, and a screw 15 is fixed on the guide block 18. An igniter is installed on the top of the mixing chamber 7.

[0024] Specifically, the vaporized methanol enters the connecting chamber 8, and is fully mixed with air by the flow guide block 18, and can then be ignited and burned by the igniter.

[0025] A protective mesh 10 is fixed inside the combustion tube 9, and a nut 14 is fixed inside the combustion tube 9, with the nut 14 corresponding to the screw 15.

[0026] Specifically, rotating the combustion tube 9 will cause the nut 14 to rotate, which in turn causes the screw 15 to slide up and down. At this time, the slide groove 17 limits the slide rod 19, so the guide block 18 slides up and down, thereby adjusting the fuel flow rate.

[0027] Multiple through holes 13 are provided inside the air supply ring 11. The through holes 13 are connected to the mixing chamber 7. An air inlet pipe 12 is fixed on one side of the air supply ring 11.

[0028] Specifically, air can be supplied through the air supply ring 11, and the through hole 13 mixes with the fuel along the periphery of the mixing chamber 7, which can ensure uniform mixing and thus ensure complete combustion of the fuel.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
