Abstract This paper is concerned with the mathematical representation of an existing box‐type furnace for the thermal dehydrogenation of ethane. The furnace is composed of a preheating convection section and a radiant heated section. The two models considering (i) the tube‐side calculation and (ii) the radiant heat transfer in the combustion chamber are independent of each other. A study is made of the effects of pressure, heat flux level and “steam/hydrocarbon” ratio on the effluent composition. A significant improvement in reactor operation if a more uniform heat flux could be achieved is predicted. From the radiant heat transfer computations an unexpected variation in flame temperature in the furnace under study was detected.
