[0037] The combustion principle and ignition process of the present invention are as follows: Figure 8 and Figure 9 As shown, the arrows in the figure indicate the flow direction of the mixed gas;

[0038] Outer ring gas combustion: Gas is injected from the outer ejector tube 11 and mixed with air. The mixed gas enters the outer ring mixing chamber 71 composed of the first cavity of the burner and the gear cover through the outer air inlet pipe 44. After being mixed again, the mixed gas is ejected through the flame holes 51 on the outer ring of the gear cover to burn and form an outer ring fire.

[0039] Middle ring gas combustion: Gas is injected from the middle ejector tube 12 and mixed with air. The mixed gas enters the second cavity of the gear cover 50 through the middle air inlet pipe 45. After the second mixing, it enters the annular groove, the connecting groove and the middle fire cover 61 through the four middle ring air inlet holes 56 on the gear cover to form the middle ring mixing chamber 72 for the third mixing. The evenly mixed mixed gas is ejected from the dense small holes on the middle fire cover to burn and form the middle ring fire.

[0040] Inner ring gas combustion: Gas is injected from the inner ejector tube 31 and mixed with air. The mixed gas flows upward into the inner air inlet pipe 52 of the gear cover, and then into the inner ring mixing chamber 73 formed by the inner air inlet pipe and the inner fire cover, where it is mixed again. The evenly mixed gas is ejected from the dense small holes of the inner fire cover 62 and burns to form an inner ring fire.

[0041] Ignition process: During ignition, the ignition needle 22 discharges to the ignition eaves 46, igniting the middle ring gas ejected from the vent 55, and then igniting the entire middle ring fire. After the middle ring fire burns, it ignites the inner ring fire inward and ignites the outer ring fire outward through the ignition groove 57.

[0042] It should be noted that those skilled in the art may make various modifications and improvements without departing from the scope of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
