Gas burner and domestic cooking appliance
A gas burner for a household appliance includes a burner housing having a mixing chamber for mixing fuel gas with primary air, a gas nozzle accommodated in the burner housing and configured to inject the fuel gas into the mixing chamber, and an annular first primary air inlet provided between the gas nozzle and the mixing chamber for drawing in the primary air. The gas nozzle has a second primary air inlet which is guided through the nozzle for drawing in the primary air. The second primary air inlet is configured in a direction of flow of the primary air through the second primary air inlet to taper at least once and to widen out again. The gas nozzle has an annular fuel gas outlet opening which opens directly into the second primary air inlet.
LEAN PRE-MIX RADIANT WALL BURNER APPARATUS AND METHOD
A staged, lean pre-mix radiant wall burner having an internal staged fuel discharge tip and an internal flow diverter, and a method of using the radiant wall burner, which allow the combustion of a high hydrogen content fuel without the occurrence of flashbacks and which also provide reduced NO.sub.x emissions and allow a closer spacing of the burners when installed in a wall, floor, or ceiling of a fired heater in a multiple burner arrangement.
Tiered burner
A tiered burner having a Venturi tube in fluid communication with and connected to a chamber, the chamber being in fluid communication with rows of burner ports; the chamber having an outer wall and an inner wall; a plurality of vanes having a tiered arrangement, wherein the lowermost vane of the plurality of vanes is the smallest vane; each vane of the plurality of vanes having an inner edge extending from the inner wall towards a center of the plurality of vanes, and extending above a row of burner ports of the plurality of rows, such that flames emitted from the row of burner ports is impinged from above and thus directed towards the center of the plurality of vanes; and the Venturi tube having: a constricted midsection; a first end creating a connection to the chamber; and a second end configured to receive gas from a gas source.
Pan support, a gas stove and a method for producing a pan support
A pan support according to the invention for a gas stove comprises a support structure for a pan having a support surface for the pan, a chamber for a gas, in particular for an inflammable combustion mixture, the chamber being arranged in the interior of the support structure. Gas outlet openings are provided at the support structure and have a fluid connection to the chamber. The chamber has a circumferential geometry when looking from above.

Burner with an optional pilot
A burner assembly includes a base body. A cap is positioned on the base body such that the base body and the cap collectively define a plurality of flame ports. A pilot insert is mounted to the base body. The pilot insert and the base body collectively defining a pilot port. An igniter is configured to generate an ignition spark. An upper spark target is positioned proximate the plurality of flame ports, and a lower spark target is positioned proximate the pilot port. An electrode of the igniter is positionable proximate either the upper spark target or the lower spark target.

COOKING APPLIANCE WITH MULTI-BURNER GAS OVEN CONTROL
A multi-burner gas oven control system is used in a cooking appliance to control multiple gas burners disposed in one or more cooking cavities of the cooking appliance. Each gas burner has an associated dedicated gas valve that is coupled to a gas supply through a common, shared gas valve, as well as an igniter that is used to ignite the gas supplied to the gas burner. During activation of a selected gas burner, all igniters are activated in connection with activating the shared gas valve and the dedicated gas valve for the selected gas burner. In addition, in some instances individual ignition sensors may be used to both confirm ignition of the selected gas burner and detect ignition of any unintended gas burner.

Cooking apparatus and control method thereof
The present disclosure relates to a cooking apparatus including a heating device, a gas passage to guide gas supplied from the outside to the heating device, a gas valve configured to supply gas to the gas passage, a modulating valve configured to adjust the degree of opening of the gas passage, a boosting passage formed to be branched from a first portion of the gas passage and joined to a second portion of the gas passage positioned in the rear of the first portion along a direction in which gas in the gas passage flows, a boosting valve configured to open and close the boosting passage, a first nozzle disposed between the first portion and the second portion of the gas passage, and a second nozzle disposed between the second portion of the gas passage and the heating device.
