Abstract
An improved process and article of manufacture to advance heater performance and reduce the cost of delayed coker charge heaters. Such improved performance is realized by routing delayed coker feedstock through a double row, double fired, heating conduit thus creating a channel to contain previously heated flue gas and resulting in the introduction of downflow, backside convective heat transfer to the interior portion of the heating conduit. When replacing the present art's single row coker tubes with the double row heating conduit afforded by the instant invention, the backside convective heat transfer introduced to the interior portion of the heating conduit eliminates the necessity of double firing the present art's single row coker heater tubes to achieve similar results.
