Remote staged furnace burner configurations and methods
Abstract
A remote staged furnace burner configuration includes placement of secondary fuel gas nozzles remote from burners. This configuration brings about an increased mixing of secondary fuel with furnace flue gases. As a result, the temperature of the burning fuel gas is lowered and NOx formation is reduced.
