| Abstract: | CFD commercial software wae used to simulate the flow field and gas admixture of regenerative ladle heating device. Different conditions that influence the gas admixture were compared, such as the inlet velocity of combustion air, the distance between air burner and gas burner, the preheating temperature of combustion air. Furthermore, the extent and tendency of the influences were analyzed quantitatively. The results are valuable for the rational design of combustion train of generative ladle heating device. |
