Abstract

The invention relates to a burner (B) for firing a combustion chamber, having a supply duct (Z1) for supplying combustion gas or combustion air into the combustion chamber, wherein the burner (B) has an inlet opening (E) via which flue gas (4) can flow into the supply duct (Z1). To be able to adjust the flow rate of the flue gas (4) flowing into the supply duct (Z1), the burner (B) comprises an adjustable throttle device (D).
