Abstract
A burner apparatus utilizes a reticulated member to promote mixing of a fuel and oxidizer mixture. A plurality of exit ports, disposed on a wall or surface encapsulating the reticulated member, defines exit streams of the mixture that produces flames upon combustion. The burner apparatus have high heating rates and turndown ratios of at least about 18:1.
Claims34
A burner comprising:
- means for mixing fuel and oxidizer, comprising a porous member having a plurality of random flow paths;
- and
- a peripheral wall having a plurality of exit ports disposed therein positioned downstream of the means for mixing wherein the exit ports are constructed and arranged to effect a minimum flow velocity of the mixture of fuel and oxidizer,
- wherein the porous member comprises an annular metal foam disposed adjacent an inner surface of the peripheral wall.
A method of combustion comprising:
- introducing a naturally aspirated fuel/air mixture into a burner without using forced air;
- passing the fuel/air mixture through a member having a plurality of random flow paths, and a plurality of ports different from the member;
- and
- combusting the fuel/air mixture downstream of the plurality of exit ports.
The method of claim. 29, wherein the cooking appliance comprises a cooking utensil support assembly providing a separation distance of less than about 2 inches between a heating surface of a cooking utensil and a top surface of the burner.
