This paper presents results from computer simulations for industrial olefin furnace. The furnaces include a gas fired propylene cracker heater. The systems have been modeled using a CFD-based,combustion flow model, in both cases the empty reactor and reactor equipped with ceramic rod.To simulating model Runge-Kuta method with steady state assumption in which the speed of production and consumption is equal radicals; has been used. Results of the two modes are evaluated by development of mathematical equations, modeling and simulation of the cases. According to the simulation results, outlet gas temperature of reactor with ceramic rod is about 30 degrees higher than the gas temperature in the simple reactor. Although the ceramic rod in the reactor cause increase in pressure drop, it can increase the Product rate to 1.157 times greater thansimple one. The model is validated with industrial - experimental results
