[0034] Working principle:

[0035] Step 1: Outside air enters the flame combustion chamber 18 through air inlet 15;

[0036] Step 2: Pure methanol enters the pure methanol coil 12 through the pure methanol inlet 19. The pure methanol coming out of the pure methanol coil 12 enters the flame combustion chamber 18 through the shower head 17. Air and pure methanol are combusted under the action of the ignition needle 23 to produce hot gas.

[0037] Step 3: The hydrogen-containing gas mixture from the fuel cell stack exits through the fuel cell stack hydrogen outlet and gas inlet 20, and enters the flame combustion chamber 18 to participate in combustion.

[0038] Step 4: Methanol-water enters methanol-water coil 11 through methanol-water inlet 21. Methanol-water (high-temperature liquid) exiting methanol-water coil 11 sequentially enters the fourth chamber 9 filled with reforming catalyst, the third chamber 8 filled with reforming catalyst, the second chamber 7 filled with reforming catalyst, and the first chamber 6 filled with reforming catalyst. Under the action of the reforming catalyst, hydrogen-rich gas is generated and flows out through hydrogen-rich gas outlet 22.

[0039] Step 5: Fill the first chamber 6, the second chamber 7, the third chamber 8, and the fourth chamber 9 of the reforming catalyst with thermocouples 5, and monitor the temperature changes of the four chambers at all times.

[0040] Step Six: The first stage of methanol-water combustion is ignited in the flaming combustion chamber 18, generating heat which is then passed through the flaming combustion hot gas channel 14 and into the flameless combustion catalyst-filled chamber 10. During this process, under the action of the catalyst, methanol-water is decomposed, generating a large amount of heat to supply the energy required for step four. In the second stage, pure methanol is produced in the first stage of methanol combustion through the pure methanol coil 12, vaporized, and directly enters the flameless combustion catalyst-filled chamber 10. Under the action of the catalyst, the reaction continues, providing heat to continuously supply the energy required for the reaction in step four.

[0041] Step 7: The exhaust gas from the flameless combustion catalyst chamber 10 enters the exhaust gas passage 4 and is then discharged through the exhaust gas outlet 16.
