Abstract

LA PARED OBLICUA DEL LECHO (6) DE LA UNIDAD PRINCIPAL DE HORNO (1) ESTA INCLINADA EN DIRECCION DESCENDENTE HACIA LA SALIDA DE DESCARGA DE CENIZAS (5), FORMANDOSE PAREDES LATERALES OBLICUAS (24R, 24L) EN LAS PAREDES LATERALES IZQUIERDA Y DERECHA (1C, 1D) DEL LADO DE SALIDA (4) DE LA UNIDAD PRINCIPAL DEL HORNO (1), E INSUFLANDOSE DESDE LAS CAPAS DE FLUIDO LATERALES (RS, LS) MATERIAL DE LECHO FLUIDO (S) QUE SE GUIA AL INTERIOR DE LA CAPA DE FLUIDO CENTRAL (CS). EL MATERIAL DE LECHO FLUIDO (S) ES OBLIGADO A CIRCULAR SUCESIVAMENTE DESDE LA CAPA DE FLUIDO CENTRAL DEL LADO DE ENTRADA (4), POR LA CAPA DE FLUIDO CENTRAL (CS) DEL LADO DE SALIDA DE DESCARGA DE CENIZAS (5), LAS CAPAS DE FLUIDO LATERALES (RS, LS) DEL LADO DE SALIDA DE DESCARGA DE CENIZAS (5), LAS CAPAS DE FLUIDO LATERALES (RS, LS) DEL LADO DE ENTRADA (4) Y LA CAPA DE FLUIDO CENTRAL (CS) DEL LADO DE ENTRADA (4), POR MEDIO DE AIRE DISPERSANTE EMITIDO DESDE TUBOS DE AIRE DISPERSANTE (21A, 21B, 25). DE ESTE MODO, EL MATERIAL DE LECHO FLUIDO(S) ES OBLIGADO A CIRCULAR VIRTUALMENTE EN UN PLANO HORIZONTAL SIN PAREDES DE DIVISION, REALIZANDOSE UNA COMBUSTION LENTA DEBIDO A LA VELOCIDAD LENTA DEL FLUIDO, PARTICULARMENTE EN LA ZONA DE SECADO Y PIROLIZACION, CONSIGUIENDOSE UNA COMBUSTION ESTABLE Y SUPRIMIENDOSE LA GENERACION DE MONOXIDO DE CARBONO Y DIOXINA.
