SR4  Combustão    Titulo: DEVELOPMENT AND TEST IN SITU OF A LOW FLUX HEAVY OIL BURNER   Resumo : ABSTRACT. THE IMPORTANCE OF FUEL ATOMIZATION IN THE COMBUSTION PROCESS AND HOW TO DO IT IN OUR SPECIFIC APPLICATION WERE DISCUSSED. A TWIN FLUID ATOMIZER (AIR/HEAVY OIL) WAS PROPOSED TO SUBSTITUTE THE ORIGINAL ONE IN AN OPEN BAKING FURNACE OF AN ALUMINUM SMELTER. THE NEW HEAVY FUEL OIL BURNER, DEVELOPED WITH SELF-RESOURCES, IS COMPARED WITH THE OLD ONE IN A NEW BAKING FURNACE IN THE SAME PROCESS CHARACTERISTICS. IMPORTANT ASPECTS LIKE: OIL CONSUMPTION, FINAL ANODE TEMPERATURE IN THE WELL TOP LAYER AND THE THERMAL PROFILE IN THE COMBUSTION CHAMBER WERE ANALYZED TO PROVE THE BETTER EFFICIENCY OF THE TWIN FLUID ATOMIZER. FINALLY, THE POTENTIAL ECONOMICAL IMPACT OF THE BUMER`S CHANGE IN THE ANODE PRODUCTION COST WAS STUDIED.
