Design Optimization of Flameless-oxyfuel Soaking Pit Furnace Using CFD Technique

AbstractThe effect of the combustion chamber's configuration on the characteristics of flow and combustion parameters has been numerically investigated for a multi injecting, LPG, flameless oxy-fuel burner in a real-size soaking pit furnace, using CFD simulation. The simulation has been performed on two different furnace configurations, namely; small and large chambers of 15 m3 and 27 m3, with height to width ratios of 1.49 and 2.02 respectively and with corresponding burner capacities of 560kW and 900kW. Later a major experimental trial has been performed in order to validate the results and reasonable consistency has been observed. The predicted results, with particular focus on the temperature distribution and heat transfer rate for two cases have been studied in detail
