Combustion System, Boiler System, And Method For Operating Combustion System

Abstract: The objective of the present invention is to appropriately reuse ammonia discharged from a fuel supply system, using a simple construction. This combustion system comprises: a burner (21D) for burning ammonia to form a flame inside a furnace; a combustion gas passage through the inside of which a combustion gas generated in the furnace flows; an ammonia fuel supply system (210) for supplying ammonia to the burner (21D) as fuel; a purge gas line (221) for supplying into the ammonia fuel supply system (210) a purge gas for discharging the ammonia from the ammonia fuel supply system (210); and an ammonia supply system (220) for supplying the ammonia discharged from the ammonia fuel supply system (210) into the combustion gas passage.
