| Abstract: | The on-line spalling of delayed coking heater was conducted using single way variable temperature spalling,two way asynchronous variable temperature spalling and two way synchronous variable temperature spalling technologies respectively.The industrial application results showed that the effect of the latter was the best.After spalling,the temperature on the furnace tubes decreased by 4-70℃ and the lowed radiation section reduced by over 35℃. |

| Keywords: | delayed coking unit on-line spalling furnace heat efficiency |
