Zusammenfassung:A combustion system (200) is provided. The combustion system (200) includes a combustion zone (220) including a burner for converting a fuel, under fuel rich conditions, to a flue gas, an intermediate staged air inlet (232) downstream from the combustion zone for supplying intermediate staged air to the flue gas and producing fuel lean conditions, and a reburn zone (224) downstream from the intermediate staged air inlet for receiving the flue gas. Système de combustion (200). Le système de combustion (200) comprend une zone de combustion (220) comportant un brûleur qui convertit un combustible, dans des conditions riches en combustible, en gaz de combustion; une entrée dair intermédiaire (232) en aval de la zone de combustion afin dacheminer lair intermédiaire vers le gaz de combustion et de produire des conditions pauvres en combustible; et une zone de rebrûlage (224) en aval de lentrée dair intermédiaire afin daccueillir le gaz de combustion.
