Three Dimensional Simulation of a Top Fired Furnace

A 3D Zonal analysis method was applied to an industrial Top Fired furnace. The radiation heat transfer was considered from all gases and surfaces in furnace. Flue gases in furnace were assumed to be non-gray. A maximum temperature in external tube skin was obtained. The results show that a variation in extinction coefficient of combustion gas and effective emissivity of tubes results an insignificant effects on temperatures of tube skin. Also effect of important parameters in the furnace and reactors were discussed.
