Abstract: Fuel thermal bake-out is a new method to heat and start up the aluminum reduction cell.And the fume thermal technology,i.e. using high-temperature fume to heat and start up the aluminum reduction cell, is an ideal method to heat the aluminum reduction cell, which can overcome the shortage of fuel thermal bake-out.The study on the rational burner structure is the key to obtaining perfect thermal result.A study on combustion in the burner for fume thermal bake-out was made by numerical simulation.Combustion performance and influencing factors of the burner were predicted.The study showed that installing a precombustion chamber could help improve complete combustion of the burner.The terfiary air near the chamber wall could lower the temperature of the chamber inner wall.The study results provided the theoretical basis for optimum design of burner structure.
