Abstract: 

AN EXPERIMENTAL INVESTIGATION OF PREMIXED METHANE/AIR COMBUSTION WITHIN A NOVEL POROUS CERAMIC BURNER IS DESCRIBED IN THIS PAPER. THE BURNER IS COMPOSED OF THREE RECTANGULAR POROUS CERAMIC LAYERS STACKED ON EACH OTHER AND INSULATED AROUND THE CIRCUMFERENCE. THE UPSTREAM LAYER IS ASSUMED TO BE THE PREHEAT ZONE, WHILE THE OTHERS ARE SERVED AS THE COMBUSTION ZONES. THE OPERATING PARAMETERS INCLUDE FUEL/AIR MIXTURE FLOW RATE AND EQUIVALENCE RATIO. THE MAIN OBJECTIVES OF THIS STUDY ARE DOCUMENTING THE FLAME STABILIZATION WITHIN THE BURNER AND DETERMINATION OF OPERATING RANGE. THE BURNER IS TESTED OVER THE RANGE OF LEAN LIMIT (F£0.65). THE EXPERIMENTAL DATA DEMONSTRATES THE ADVANTAGES OF BURNING A COMBUSTIBLE GAS INSIDE THE POROUS CERAMIC BURNER. THE BURNER SHOWS A GREAT ABILITY TO EXTEND THE BLOW OFF LIMIT AT EACH EQUIVALENCE RATIO.
