At least some embodiments a flare includes a gasket sized and shaped to prevent gas-leakage at the gas slot when pressure of gas entering the flare is below a designed minimum opening pressure that causes the flare bowl to move away from the tip housing. At least some embodiments of a flare includes a diaphragm spring coupled with the flare bowl to assist in movement of the flare bowl with respect to the tip housing to vary an opening dimension of a gas-exit slot defined by the flare bowl and the tip housing.

Emissions of NOand/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 NOcontent 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.
