Abstract
A gas burner is provided with a rich combustion chamber contiguous with a second combustion chamber through which combustion air enters in predetermined flow patterns to enable the burner to be self-stabilizing in a highly efficient manner. The rich combustion chamber receives air through a first port arrangement which, among other things, establishes underpressure zones at the center of the rich combustion chamber and air layer zones thereabout. Combustion air is supplied to the second chamber by a second port arrangement which, among other things, assures thorough combustion therein independent of the burner firing rate. When a longitudinal stream of gaseous fuel is exhausted into the rich combustion chamber, the underpressure zones force same outwardly to mix with combustion air in the first chamber while positive pressure in the second chamber is effective to recirculate a portion of the mixture whereby a sufficient combustion level is achieved in the rich combustion chamber to minimize carbon formation while the air layer zones resulting from the first port arrangement assure that carbon will neither be formed nor deposited therein.
