Original abstract

Radiation tubular furnace type is the simplest tubular furnace. Tube coil is placed around the wall inside vertical cylindrical radiant (combustion) chamber. Coil can be solved as classical vertical type (i.e. vertical straight tubes connected to 180 degree elbow) or as spiral type for minimisation of fluid pressure drop. Tube coil arrangement dominantly influences thermal-hydraulics characteristics of furnace and its economy. Presented method is based on standard long time used design methods (Lobo-Evans method, Belokon method). It is shown, how these standard global design methods can be (for common-operating conditions) suitable generalised and simplified. It allows (for purpose of optimum design of coil arrangement) to arrange the basic heat transfer equation for radiant chamber. In connection with investment cost relations for individual furnace subsystems (tube coil, burners, lining, etc.) and operating cost relations (fuel consumption, fluid pumping cost) can be obtained final objective function of total cost. This objective function then allows finding the optimum coil arrangement from minimum total cost point of view. Moreover, obtained results allow formulating some general recommendations suitable for furnace designers. Developed method can be used for individual solution of radiation type of tubular furnaces and also for first (preliminary) design stage usually connected with proposal for customer when only basic process and furnace design data are usually known. Developed method can be also used for effective solution of integration of radiation furnaces into processes. Application of the developed method is demonstrated through a case study – optimum arrangement of coil in gas plant regeneration furnace.
