Burner with flame stability

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 extending beginning from the second interior surface of the burner body to the exterior surface of the burner body and 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 burner assembly at which a combustible gas is combusted comprising:

• a burner body including a combustible gas chamber for holding the combustible gas and a plurality of burner ports, the combustible gas chamber being formed between a first interior surface and a second interior surface spaced from the first interior surface, the first and second interior surfaces being joined by a connecting interior surface;
• a stability chamber in gas-flow communication with the combustible gas chamber, whereby the combustible gas can flow from the combustible gas chamber to within the stability 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 so that 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 including at least one upper edge that is adapted to engage the undersurface of a burner cap for closing off the top of the burner body, the at least one upper edge of the stability chamber being configured so as to prevent movement of the burner cap on the burner body in at least one direction laterally of the burner body when the at least one upper edge of the stability chamber and the undersurface of the burner cap are engaged
• wherein the stability chamber includes two side walls each of which includes a respective one of two upper edges of the stability chamber, each of the two upper edges including a first portion and a second portion aligned substantially end to end with the second portion of the upper edge being located below the first portion of the upper edge nearer the bottom of the stability chamber, at least one of the two upper edges of the stability chamber including a third portion aligned substantially end to end with the second portion of the at least one of the two upper edges and the second interior surface, and extending between the second portion and the second interior surface, the third portion of the at least one of the two upper edges of the stability chamber forming at least a portion of an opening in one of the side walls of the stability chamber that provides gas-flow communication between the combustible gas chamber and the stability chamber, whereby combustible gas can flow from the combustible gas chamber to within the stability chamber.
