Abstract:
1. A burner assembly at which a combustible gas is combusted comprising: a burner body comprising an exterior surface, a first interior surface and a second interior surface spaced from the first interior surface, the first interior surface and the second interior surface being joined by a connecting surface to form a combustible gas chamber; a plurality of burner ports providing openings in the exterior surface of the burner body and the first interior surface of the burner body through which the combustible gas can pass from the combustible gas chamber to the exterior of the burner body and be combusted at the burner ports exterior of the burner body; and a stability chamber in gas-flow communication with the combustible gas in the combustible gas chamber for maintaining the combustion of the combustible gas in the stability chamber whenever the combustion of the combustible gas at the plurality of burner ports is disturbed, whereby the combustion of the combustible gas at the plurality of the burner ports may be resumed upon the cessation of the disturbance, the stability chamber comprising a pair of oppositely disposed side walls, each of which extends from a first end beginning at the second interior surface of the burner body to a second end at the exterior surface of the burner body, at least one of the side walls having an opening that provides gas-flow communication between the combustible gas chamber and the stability chamber, whereby the combustible gas can flow from the combustible gas chamber to within the stability chamber, a front wall located at the second interior surface and joining the first ends of the oppositely disposed side walls of the stability chamber, a rear wall at least partially joining the second ends of the oppositely disposed side walls, and a bottom wall joined to the pair of oppositely disposed side walls, the front wall and the rear wall so as to close off the bottom of the stability chamber.
