Title (EN) BED MANAGEMENT CYCLE FOR A FLUIDIZED BED BOILER AND CORRESPONDING ARRANGEMENT
(FR) CYCLE DE GESTION DE LIT POUR CHAUDIÈRE À LIT FLUIDISÉ ET AGENCEMENT CORRESPONDANT
Abstract:
(EN) The invention relates to abed management cycle for a fluidized bed boiler, comprising the steps of: a) providing fresh ilmenite particles as bed material to the fluidized bed boiler; b) carrying out a fluidized bed combustion process; c) removing at least one ash stream comprising ilmenite particles from the fluidized bed boiler; d) separating ilmenite particles from the at least one ash stream; e) recirculating separated ilmenite particles into the bed of the fluidized bed boiler. The invention also relates to a corresponding arrangement for carrying out fluidized bed combustion, comprising a fluidized bed boiler comprising ilmenite particles as bed material; and a system for removing ash from the fluidized bed boiler; wherein the arrangement further comprises a separator for separating ilmenite particles from the re- moved ash; and means for recirculating separated ilmenite particles into the bed of the fluidized bed boiler.
(FR) La présente invention concerne un cycle de gestion de lit pour une chaudière à lit fluidisé comprenant les étapes consistant à : a) fournir des particules d'ilménite fraîches en tant que matériau de lit à la chaudière à lit fluidisé; b) mettre en œuvre un procédé de combustion en lit fluidisé; c) éliminer au moins un flux de cendres comprenant des particules d'ilménite provenant de la chaudière à lit fluidisé; d) séparer des particules d'ilménite du au moins un flux de cendres; e) remettre en circulation les particules d'ilménite séparées dans le lit de la chaudière à lit fluidisé. La présente invention concerne également un agencement correspondant pour la mise en œuvre de la combustion à lit fluidisé comprenant une chaudière à lit fluidisé comprenant des particules d'ilménite en tant que matériau de lit; et un système pour éliminer les cendres de la chaudière à lit fluidisé; l'agencement comprenant en outre un séparateur pour séparer des particules d'ilménite des cendres éliminées; et des moyens permettant de remettre en circulation séparés des particules d'ilménite séparées dans le lit de la chaudière à lit fluidisé.
