From the Bottom of the Main Fractionator the Feed is pumped, along with some injected Steam, into the Fuel-Fired Furnace and heated to its Thermal Cracking temperature of about 480°C. Thermal Cracking begins in the Pipe between the Furnace and the Coke Drums, and finishes in the Coke Drum that is on-stream. The injected Steam helps to minimize the Deposition of Coke within the Furnace Tubes.
