Excess air burner

Abstract

Abstract A GAS BURNER PARTICULARLY ADAPTED FOR OPERATION WITH EXCEPTIONALLY LARGE QUANTITIES OF EXCESS AIR. THE PREFERRED EMBODIMENT OF THE BURNER COMPRISES A GENERALLY CYLINDRICAL, CERAMIC BURNER BLOCK HAVING A CENTRAL BORE WHICH INCREASES IN DIAMETER NON-UNIFORMLY FROM THE INLET TO THE OUTLET. THE GAS INLET COMPRISES A TUBE MEMBER POSITIONED AXIALLY OF THE BORE AND TERMINATING CLOSELY ADJACENT THE INLET END. A CIRCULAR FLANGE EXTENDS OUTWARDLY ABOUT THE END OF THE TUBE INTO CLOSE PROXIMITY WITH THE BORE TO DEFINE A NARROW ANNULAR GAP OR SPACE. AIR IS SUPPLIED ANNULARLY OF THE TUBE AND FLOWS THROUGH THE NARROW GAP WITH SUBSTANTIAL VELOCITY. THIS CAUSES A VACUUM ACROSS THE FACE OF THE FLANGE AND GAS SUPPLY TUBE TO PRODUCE GOOD MIXING EFFICIENT COMBUSTION. BY PROPERLY RELATING THE SIZE OF THE FLANGE, THE ANNULAR OPENING AND THE BORE, THE BURNER GIVES EXCELLENT COMBUSTION CHARACTERISTICS THROUGHOUT SUBSTANTIAL VARIATIONS IN GAS-AIR RATIOS.
