Title (EN) A COOLER FOR COOLING OF PARTICULATE MATERIAL, ESPECIALLY FINE-GRAINED DUST
(FR) REFROIDISSEUR POUR REFROIDIR LES MATIERES PARTICULAIRES, NOTAMMENT LES POUSSIERES A GRAINS FINS
Abstract:
(EN) A cooler for particulate material from a combustion plant, especially for cyclone ash form a PFBC power plant, in which the material is transported pneumatically with flue gases as transport means. At the inlet of the cooler there is a space (40) for separation of the particulate material from the transport gas. The transport gas is removed via a gas cleaner (56). The particulate material (44) is collected in a duct (42) where it forms a particle column. The duct includes cooling modules (48a-c), suitably water-cooled, which cool the material on its way down through the duct. The duct comprises devices for the supply of a gas which removes flue gases from the material in the duct.
(FR) Refroidisseur pour matières particulaires provenant d'une installation de combustion, notamment pour les cendres provenant des cyclones produites par une installation de combustion sur lit fluidisé pressurisé, dans laquelle les matières sont transportées par les gaz brûlés. A l'entrée du refroidisseur se trouve un espace (40) où les matières particulaires sont séparées du gaz de transport. Ce dernier est retiré au moyen d'un épurateur de gaz (56). Les matières particulaires (44) sont receuillies dans une conduite (42) où elles forment une colonne de particules. La conduite comporte des modules de refroidissement par eau (48a-c) qui refroidissent les matières pendant qu'elles passent dans la conduite. La conduite comporte des dispositifs permettant d'amener un gaz qui enlève les gaz brûlés des matières qui passent dans la conduite.
