Abstract
A rigorous method for designing delayed coking furnace is proposed in this paper. Based on Hottel's idea, the zone method is adopted for calculating radiative heat transfer. The whole system is divided into surface zones and gas zones. The temperature profiles in a furnace are thus obtained by solving a series of simultaneous energy balance equations in each zone. The direct exchanging area is essential for zone method to calculate radiative heat transfer. The direct exchanging area originally developed by Hottel and Cohen was limited to oubes and squares. In this paper, the derivation of the direct exchanging area equations are extented between any two zones in the vertical furnace. These equations are adaptable to any ladder-shaped surface or space of different sizes.
