Abstract: A cooktop burner assembly is described. The cooktop burner assembly includes a main burner, and a simmer burner located below the main burner, where a diameter of the simmer burner is greater than a diameter of the main burner. The closer placement of the main burner to a cooking vessel placed on top of the cooktop burner assembly as compared to the placement of the simmer burner from the cooking vessel increases thermal efficiency. Moreover, the farther placement of the simmer burner from the cooking vessel facilitates simmering of items in the cooking vessel and the larger diameter of the simmer burner reduces a possibility of overheating the main burner and the cooking vessel.

Abstract: A gas cooking system having a gas cooking burner that includes a gas line, a first gas port coupled to the gas line, and a second gas port disposed downstream from the first gas port, wherein at least one of the first and second gas ports comprises a non-circular geometry adapted to increase air entrainment, the second gas port further being non-rectangular if the first gas port has a circular geometry.

Abstract: Burner assembly for a cooking range is provided. The burner assembly includes a gas-heat subassembly, and a radiant heat subassembly. An electromechanical interface is configured to detachably interconnect the subassemblies to one another. The electromechanical interface is further configured to pass electrical power to the radiant heat subassembly.

Abstract: A burner apparatus having a burner tube in which is disposed a premixing tube having air communication with the air inlet end of the burner tube. An air diffuser bridges between the premixing tube and the burner tube. A baffle plate is supported by and seals across one end of the premixing tube and a plurality of gas/air mixture injection holes are dispersed in the premixing tube between the air diffuser plate and the baffle plate. A gas tube extends into the premixing tube and a plurality of gas holes are disposed along the gas tube in proximity to the discharge end of the gas tube so that air is premixed with gas and discharged from the gas holes to form a gas/air mixture which is passed from the gas/air mixture injection holes radially between the baffle plate and an air diffuser plate.

Abstract: An improved low NOx burner assembly having a burner plate assembly which is attached to a burner head portion thereof, the burner plate assembly having a burner plate and a wrapper, the burner plate having a relatively large central aperture and a plurality of smaller apertures of several diametrical sizes disposed at selected radial positions. The burner plate, attached to the burner head portion of the burner assembly via its wrapper, partially closes the outlet end of the burner head, and flame combustion is partially contained in a premixing chamber, thus effecting prolonged contact with combustion air prior to the gas and air mixture passing through the apertures of the burner plate.

Abstract: An opposed louver air damper apparatus for controlling the flow rate of combustion air to a burner fire box, comprising a plurality of adjacent, rotatable louvers having rubber tips and side gaskets providing sealing between the louvers and a frame, and geared responsive shafts supporting the louvers for controllably rotating the louvers to determinative positions to modulate the volume of air passing through the louver apparatus, wherein the gears in meshing engagement precisely maintains the relative position of the louvers, and the gaskets operate to minimize undesirable leakage through the air damper. The gears form teeth in arcuate portions of the full circumference to limit the rotational movement to only that within the toothed portion of the gear.
