Abstract

The present research is CFD simulation of industrial furnace related to Shahid Tondgouyan Petrochemical Company (STPC) to analyze the impact of operating conditions on thermal properties changes of oil and heat transfer phenomenon in the furnace and its distribution manifold with 8 passes. According to the experimental history of the furnace, the presence of more coke particles in some passes has led to their clogging, which according to the simulation results, the geometry of the oil inlet manifold in it has been effective. This manifold has created a different distribution of flow and coke particles in the 8 parallel passes of the furnace, which, in addition to the greater distribution of coke particles in some of them, has caused different oil residence times in the passes. The combustion simulation in the furnace also showed that hot spots have been created in the furnace areas, especially in the exit of combustion gases from the radiation zone to the convection zone, which could be another reason for the destruction of the oil. Also, according to the simulation results, with a decrease of 3/6 kg/s in the flow rate of an oil pass, the outlet temperature of that pass in the radiation section increased by 1/1 degrees Celsius.
