| Abstract: | Leakage occurred in a shield tube in the convection section of xylene furnace and caused fire accident.A comprehensive monitoring and analysis on this tube was carried out.And it was determined that the failure was caused by flue gas fouling sediment.During the shutdown period of the furnace,steam dripping in the soot blower resulted in the corrosion under scale on the external wall of the tube. |
