Computational Investigation of Combustion and Flow in Unit Glass Melting Furnace

Unit furnace is one ofthe most high efficiency glass melting furnaces,which has the advantages of its simple operating system,low capital expenditure,short build cycle and land saving.Key technology for designing a unit furnace is how to arrange the burners.In this paper,two kinds of burner placements are investigated by using the method of numerical simulation.The predictions show that the staggered burner placement method is better than the face to face burner placement method for the present unit glass melting furnace.The placement of staggered burner should prevent hot spots in the furnace crown and flame interference in the combustion chamber,thereby it would achieve more uniform heating and optimize heat transfer.Compared with the flame of the hot air burner,predicted results also show that the temperature of the oxygen fuel burner flame is larger,but the flame is shorter due to its low momentum.
