Numerical Simulation in Combustion Space of an Oil Fired Oxy-fuel Glass Furnace with Different Burner Arrangements

摘要

In this paper, an oil fired oxy-fuel glass furnace was designed, and the numerical simulation in the combustion space of the furnace was carried out. The optimization approach was proposed by comparing two different burner arrangements, opposed and staggered one respectively. The gas phase was expressed with k-ε two-equation model; the oil drop motion was described with Discrete Phase Model; the combustion was described with non-premixed model; the radiation was expressed with discrete ordinates radiation model. The simulation results agree well with the related references. The results show that for the design furnace in this study, it is appropriate to arrange the burners in staggered manner, since in this case the temperature is uniform, and the flow field under the crown is gentle, and also the heat transfer rate to the liquid glass surface is higher.
