Abstract Computational Fluid Dynamics (CFD) analysis of process furnaces is an important tool in the assessment of new furnace designs and especially in the assessment of furnace revamps where burner clearance may not meet current standards. CFD analysis is commonly employed to predict flame shapes to ensure that the selected burner layout will produce good flame quality at the operating conditions of interest. CFD is also used to predict the heat flux distribution onto the radiant coil. Managing the heat flux distribution is critical to ensuring long tube life and avoiding problems such as unwanted coking in the process tubes.; Quality metrics for these CFD simulations are not provided in typical engineering specifications or in standard documents such as API 560. The engineer performing the CFD modeling must use his or her judgment to select the turbulence modeling approach, combustion modeling approach, and mesh resolution. In this paper, the impact of mesh resolution on the CFD simulation of fired process heaters is evaluated with particular focus on the quantities relevant to burner design.
