Yes, You are right. Our coke uses in steel industry as addition. The fuel gas that uses has not very well combustion heat and after increasing of capacity it a reason to add new preheater. After preheater temperature of feed is 350C. Then feed mixes with recycle (HGO) and goes to the furnace. inlet drum temperature is 467-468C (usually. it corrects by results of analysis of coke)
