[0034] 2. The burner 22 is a natural gas burner: the fuel is heated by burning natural gas, and the operating cost is generally low. Considering the large cross-section of the furnace and the uneven temperature distribution, at least three burners 22 are designed, with ratio control and low-nitrogen combustion technology.

[0035] 3. Burner trolley 21, vertical cylinder 18, combustion port gate valve 19; when the temperature control of the burner 22 is not working, the burner trolley 21 automatically takes the burner 22 away from the burner combustion port 17, protects the burner 22 and controls the vertical cylinder 18 to automatically drive the combustion port gate valve 19 to seal the burner combustion port 17.

[0036] Ensure that the temperature of the vertical furnace body 10 does not leak out and does not leak air.

[0037] In addition, during incineration, avoid abnormally high temperatures during pyrolysis, and avoid violent turbulence of flue gas. When the temperature is high, the vertical furnace body is flushed with nitrogen to slow down the pyrolysis rate. At the same time, the furnace pressure is controlled at a slight negative pressure of -20-30Pa, and the flue gas avoids violent turbulence.
