the waveform generator 21 causes the loudspeaker 19 to produce a sound shock wave of a specific frequency, waveform and amplitude through the dedicated power amplifier 20, exerting a "self-excitation" effect on the overall burner.

The chamber gas mixture passes through the aluminum foil honeycomb pore plate 9 to rectify the airflow, so that the airflow becomes smoother and more uniform. The mixed gas in the inner pipeline and the outer pipeline is mixed in the respective pipelines to obtain the mixed gas with different mixing degrees. Hydrogen, carbon monoxide and methane can enter the central pipeline 4 from the central air inlet pipe 13, and then can enter the inner pipe 6 from the side wall opening of the central pipeline 4, and the mixing degree with the incoming flow can be adjusted by changing the height of the opening position, so that partial premixing combustion modes with different degrees are realized; alternatively, the top of the central duct 4 is perforated so that the gas enters the visible cylindrical combustion chamber 1 directly from the top, obtaining a non-premixed combustion mode. The mixed gas in the outer pipe 5 enters the outer pipe swirl channel 2, the mixed gas in the inner pipe 6 enters the inner pipe swirl channel 3, and due to the action of the fan blades and the inertia effect, stable rotating turbulent airflow is formed and enters the visual cylindrical combustion chamber 1.
