Abstract:

Through the cause analysis of the fracture of the second pass furnace tube in the radiation section of cracking furnace F-106, the causes of the fracture were found out, the operation and maintenance methods for cracking furnace were formulated, the service life of cracking furnace tube was prolonged, the maintenance frequency of cracking furnace was reduced, and the single operation cycle of cracking furnace was increased, so as to ensure the production of ethylene and propylene and to improve the benefit of ethylene plant.

Key words: cracking furnace, radiant section, corrosion, fracture
