Abstract

Un procesador (10) de lecho fluidificado circulante tiene un recinto (11) de procesador al menos parcialmente definido por una pared delantera (12) y una pared trasera (14) espaciada de la pared delantera (12) . Una pared inferior (16) está conectada entre las paredes delantera y trasera (12, 14) y está previsto un mecanismo (18) para suministrar aire primario a través de la pared inferior (16) para fluidificar un lecho circulante en el recinto (11) . Está previsto otro mecanismo (22) para hacer recircular el lecho desde una parte superior del recinto de nuevo al recinto. Están previstas una o más cámaras impelentes (31) de aire secundario en el recinto entre las paredes delantera y trasera para suministrar aire secundario al lecho fluidificado, por encima de la pared inferior (16) , de manera que el aire secundario penetra profundamente en el recinto. La o las cámaras impelentes están formadas por una pared de agua (38) que tiene una pluralidad de aberturas (A) en su interior para permitirla comunicación de gases y sólidos a su través desde un lado al otro de la pared de agua (38) .
