Abstract: The invention relates to an injector device (3) for a gas burner (2) of a household appliance (1), wherein the injector device (3) has a tube portion (20) through which gas (12) flows during operation of the gas burner (2), and a wall portion (21) delimiting the tube portion (20). The wall portion (21) has at least two openings (22) through which gas exits the injector device (3) during operation of the gas burner (2). The at least two openings (22) are configured to divide a single gas stream flowing through the tube portion (20) during operation of the gas burner (2) into separated gas streams (23). The invention further relates to a gas burner (2) with such an injector device (3) and to a household appliance (1) with at least one gas burner (2).

Abstract: Emissions of NO X and/or CO are reduced at the stack by systems and methods wherein a primary fuel is thoroughly mixed with a specific range of excess combustion air. The primary fuel- air mixture is then discharged and anchored within a combustion chamber of a burner. Further, the systems and methods provide for dynamically controlling NO X content in emissions from a furnace by adjusting the flow of primary fuel and of a secondary stage fuel, and in some cases controlling the amount or placement of combustion air into the furnace.
