Title (EN) ASH TREATMENT AND REINJECTION SYSTEM
(FR) SYSTÈME DE TRAITEMENT ET DE RÉINJECTION DE CENDRES
Abstract:
(EN) A method and apparatus are provided for treating exhaust from a solid fuel combustion system such as a furnace or boiler and includes combusting a material in the combustion chamber and separating fly ash and char from a flue gas stream. The separated fly ash and char mixture is then separated further by separating smaller ash particles from larger char particles. The larger char particles are then reduced in size by a reducing device such as a grinder or crusher. Char particles that have been reduced in size by the grinder or crusher are then reinjected into the combustion chamber for re-burning.
(FR) L'invention concerne un procédé et un appareil destinés à traiter l'échappement en provenance d'un système de combustion de combustible solide, tel qu'un four ou une chaudière, et comprenant la combustion d'un matériau dans la chambre de combustion et la séparation des cendres volantes et des résidus de carbonisation à partir d'un courant de gaz de combustion. Le mélange séparé de cendres volantes et de résidus de carbonisation est ensuite séparé davantage au moyen de la séparation des particules de cendre plus petites à partir des particules de résidu de carbonisation plus grandes. La taille des particules de résidu de carbonisation plus grandes est ensuite réduite au moyen d'un dispositif réducteur, tel qu'un broyeur ou un concasseur. Les particules de résidu de carbonisation, dont la taille à été réduite au moyen du broyeur ou du concasseur, sont ensuite réinjectées dans la chambre de combustion pour une nouvelle combustion.
