Abstract

UN REACTOR DE LECHO FLUIDIZADO (10) Y UN METODO PARA GOBERNARLO, EN EL QUE UN LECHO DE MATERIAL PARTICULADO (30A, 30B) SE SOPORTA EN UN EMPARRILLADO (22) EN UN CIERRE (12). SE PASA AIRE A TRAVES DEL EMPARRILLADO (22) PARA FLUIDIZAR EL MATERIAL PARTICULADO Y PROMOVER LA COMBUSTION DEL COMBUSTIBLE. SE DISPONE UNA UNIDAD DE SEPARACION (50, 52, 54, 56) POR LO MENOS ADYACENTE A CADA UNA DE LAS DOS PAREDES (14, 16) QUE FORMAN EL CIERRE (12) PARA RECIBIR LA MEZCLA DE AIRE, LOS PRODUCTOS GASEOSOS DE LA COMBUSTION Y EL MATERIAL PARTICULADO RELATIVAMENTE FINO INTRODUCIDO POR EL AIRE Y LOS PRODUCTOS GASEOSOS DE LA COMBUSTION. CADA UNIDAD DE SEPARACION (50, 52, 54 56) FUNCIONA PARA SEPARAR EL MATERIAL PARTICULADO DE LA MEZCLA, Y SE ASOCIA UNA UNIDAD DE DISTRIBUCION (70, 72, 74, 76) A CADA UNIDAD DE SEPARACION PARA ADMITIR EL MATERIAL PARTICULADO SEPARADO Y DISTRIBUIRLO AL LECHO EN MUCHOS PUNTOS.
