Abstract
Increased turndown ratio is achieved by providing an atmospheric gas burner having a burner body with a plurality of ports formed therein and a fuel flow divider disposed in the burner body. The fuel flow divider defines a primary fuel chamber and at least one secondary fuel chamber, wherein the secondary fuel chamber is in fluid communication with at least one of the ports and the primary fuel chamber is in fluid communication with the remaining ports. A first mixing tube introduces a fuel-air mixture into the primary fuel chamber, and a second mixing tube introduces a fuel-air mixture into the secondary fuel chamber.
Claims13
A gas burner comprising:
- a delta shaped burner body having a center region and a plurality of radial legs and a plurality of ports formed therein;
- a delta shaped fuel flow divider having a plurality of diffuser sections corresponding with said plurality of radial legs and disposed in said burner body, said fuel flow divider defining a primary fuel chamber and at least one secondary fuel chamber, wherein said secondary fuel chamber is in fluid communication with at least one of said plurality of ports and said primary fuel chamber is in fluid communication with the remaining ones of said plurality of ports;
- means for introducing a fuel-air mixture into said primary fuel chamber;
- and
- means for introducing a fuel-air mixture into said secondary fuel chamber.
A gas burner comprising:
- a burner body having center region with a plurality of legs radiating outward therefrom and having a plurality of ports formed therein;
- a fuel flow divider having center region with a plurality of diffuser sections radiating outward therefrom, said fuel flow divider being disposed in said burner body so that each one of said diffuser sections is located in a corresponding one of said burner body legs, said fuel flow divider defining a primary fuel chamber and a plurality of secondary fuel chambers, wherein each one of said secondary fuel chambers is in fluid communication with a separate set of at least one of said plurality of ports and said primary fuel chamber is in fluid communication with the remaining ones of said plurality of ports;
- a primary mixing tube for introducing a fuel-air mixture into said primary fuel chamber;
- and
- a secondary mixing tube for introducing a fuel-air mixture into said secondary fuel chambers.
