Why Are "Wolf Tooth Bars" (Also Known as Coking Breakers or Stirring Rakes) Equipped in Oil Sludge Pyrolysis Equipment?

"Wolf tooth bars" (coking breakers/stirring rakes) are installed in oil sludge pyrolysis equipment to address core pain points in the pyrolysis process, with the following key functions:

Prevent coking and wall adhesion

Heavy asphaltenes and resins in oil sludge easily coke on the reactor inner wall at high temperatures, which reduces heat transfer efficiency and may even block the equipment. The toothed structure of the wolf tooth bar scrapes off coking in real time, ensuring stable and continuous operation.

Enhance material mixing and heat transfer

The stirring action ensures uniform flow of oil sludge in the reactor, avoiding local overheating or uneven heating, thereby improving pyrolysis efficiency and oil yield, while also enhancing product stability.

Assist slag discharge and extend service life

Carbon residue after pyrolysis tends to adhere to the bottom of the equipment. The wolf tooth bar loosens this material, helping the slag discharge system operate smoothly, reducing the frequency of shutdowns for decoking, and extending the continuous operation time and service life of the equipment.

Optimize reaction environment

Uniform material mixing reduces local carbon accumulation, allowing more complete pyrolysis and lowering equipment failure rates caused by overheating or coking.
