Title
(EN) BIOMASS DIRECT REDUCED IRON
(FR) FER DE RÉDUCTION DIRECTE À BASE DE BIOMASSE
Abstract
(EN) A method and an apparatus for "recycling" a significant amount of heat within a linear hearth furnace by means of an endless conveyor that transports briquettes through the furnace from an inlet (briquette feed) end to an outlet (DRI discharge) end and then returns to the inlet end and transfers a significant amount of heat from the outlet end to the inlet end of the furnace.
(FR) L'invention concerne un procédé et un appareil pour le "recyclage" d'une quantité importante de chaleur dans un four à sole linéaire au moyen d'un transporteur sans fin qui transporte des briquettes à travers le four depuis une extrémité d'entrée (alimentation de briquettes) jusquà une extrémité de sortie (décharge de fer de réduction directe), puis revient à l'extrémité d'entrée et transfère une quantité significative de chaleur depuis l'extrémité de sortie jusqu'à l'extrémité d'entrée du four.
