Abstract

Abstract: A state computational fluid dynamics (CFD) model was developed to predict the combustion and heat transfer of a large tube furnace. The model studied the threedimensional numerical simulation of combustion, flow, heat and mass transfer process, by using kε turbulent flow model, composition PDF transport model and DO radiation model. The CFD simulations reflect chaotic hydrodynamics flow in furnace. The predicted results were in good agreement with the industrial process data. This model provided the theoretical reference for designing and optimizing furnace.
