A process and apparatus are disclosed for heating a coking feedstock to a temperature sufficient to effect coking of the coking feedstock in a coking drum, said process and said apparatus being characterized by the fact that the heating is conducted in a double fired heater in which the coking feedstock is heated by flames located on opposite sides of the tubing through which the feedstock flows. The process and apparatus allow for increased coke production and extended operating periods.
