Numerical-Experimental Study of the Gas LP Atmospheric Burner

A numerical-experimental study of the gas LP atmospheric burner used in the ceramist furnace is presented. A new design of the burner was proposed to obtain a temperature distribution in the furnace better that the temperature distribution obtained with the actual burner. The experimental study helped to know the temperature and flame distribution in the furnace that permit to achieve the temperature of baking of the ceramic. The experimental results were obtained with a thermal camera and thermocouples placed in the furnace. Numerical models were developed with CFD (Fluent ®) comparing the results with the experimental results to obtain the new design of the burner. The experimental and numerical results permitted to identify the zones with temperature near to the temperature of baking, which is reached in the high and intermediate zones of the furnace. Then it is necessary a recirculation of the hot gases toward the low zone of the furnace.
