When pyrolyzing waste, the burner 9 can be started, and the flame generated by the burner 9 is sprayed into the middle position of the inner liner 16. Then, the high-pressure air pump 7 is started, and the high-pressure gas generated by the high-pressure air pump 7 enters the gas cavity inside the flame spraying cylinder 6 along the air guide pipe 8. Since a plurality of spirally distributed air outlet holes are arranged on the outer surface of the inner liner 16, the high-pressure gas in the gas cavity can be ejected from the air outlet holes, and the air inside the inner liner 16 rotates at a high speed, so as to gather the flame at the middle position, and finally be ejected from the outlet end of the flame spraying cylinder 6, and can perform high-temperature pyrolysis operation on the waste inside the furnace body 1.

When the exhaust gas generated by the thermal cracking of the waste is discharged, the cooling water passes through the interior of the heat exchanger 2 through the water guide pipe 3, and the heat energy in the exhaust gas can be effectively recovered at this time.
