Abstract
The invention provides a plural chamber gas burner for a cooking grill. The burner has an inside space between a top and a bottom. Divider walls divide the inside space into a breather space between two independently operable gas chambers. Breather apertures in the bottom of the burner provide communication between the breather space and the outside of the burner. Ignition apertures are provided in the divider walls near burner apertures in the gas chambers so that gas from an already operating gas chamber will ignite gas of another gas chamber.
Claims12
A plural chamber gas burner for use in a cooking grill, comprising:
- a structure having a top and bottom, said top and bottom defining an inside space;
- at least one divider wall extending between said top and bottom dividing said inside space into first and second independently operable gas chambers;
- a plurality of burner apertures in said structure for communication between each gas chamber and the ambient air;
- gas feeder apertures in said structure for communication between each gas chamber and a source of gas;
- and
- at least one ignition aperture in said divider wall forming part of a path from one gas chamber to the other gas chamber sufficient to permit gas from one gas chamber to ignite gas from the other gas chamber, the size of said ignition aperture being small enough to permit independent operation of said gas chambers.
A plural chamber gas burner for use in a cooking grill, comprising:
- a structure comprising a top and a bottom, said top and bottom defining an inside space;
- first and second divider walls extending between said top and bottom dividing said inside space into an intermediate breather space between first and second independently operable gas chambers;
- a plurality of burner apertures in said structure for communication between each gas chamber and the ambient air;
- gas feeder apertures in said structure for communication between each gas chamber and a source of gas;
- and
- a plurality of breather apertures in said structure for communication between said breather space and the ambient air.
