Abstract

REACTOR CON LECHO FLUIDO CIRCULANTE QUE COMPORTA UNA ZONA INFERIOR (3) CON REJILLA DE FLUIDIZACION (11), INYECCION DE AIRE PRIMARIO Y SECUNDARIO (12, 13) Y ALIMENTACION DE COMBUSTIBLE (10), UNA ZONA SUPERIOR (2), UNOS LECHOS FLUIDOS DENSOS (22, 23) EN LO ALTO DE LA ZONA INFERIOR (3) QUE PURGAN LAS MATERIAS SOLIDAS EN LA RECIRCULACION INTERNA DEL REACTOR Y LAS ENVIAN PARCIALMENTE EN LOS INTERCAMBIADORES EXTERIORES CON LECHO FLUIDO DENSO REUNIDOS CONTRA LAS PAREDES DEL REACTOR AL NIVEL DE LOS LECHOS INTERNOS (22, 23). ESTOS INTERCAMBIADORES EXTERIORES RECHAZAN LAS MATERIAS, DESPUES DEL INTERCAMBIO DE CALOR CON UN FLUIDO EXTERIOR, EN LA ZONA INFERIOR (3). REACTOR DE CONSTRUCCION SIMPLE QUE BENEFICIA UNAS MEJORAS DE LOS LECHOS EXTERIORES DENSOS QUE MANTIENEN UNA CONSTRUCCION CLASICA DE LA ZONA INFERIOR (3).
