Abstract

UNA CENTRAL CON REFRIGERADOR DE CENIZAS CON TRANSPORTADOR DE TORNILLO HELICOIDAL. UNA CENTRAL, POR EJEMPLO, DEL TIPO PFBC, CON UN REFRIGERADOR (50) PARA ENFRIAR LAS CENIZAS PROCEDENTES DEL CICLON (14) Y/O UN LECHO FLUIDIZADO (26). EL REFRIGERADOR (50) COMPRENDE UN CILINDRO (52) CON UN TORNILLO HELICOIDAL DE TRANSPORTE (54) QUE TRANSPORTA LAS CENIZAS (92) POR EL CILINDRO (52). EL TORNILLO HELICOIDAL DE TRANSPORTE (54) TIENE UN EJE TUBULAR (70) QUE ES ATRAVESADO POR AGUA DE REFRIGERACION. EL CILINDRO (52) PUEDE REFRIGERARSE POR AIRE O POR AGUA. EN EL FONDO DEL CILINDRO (52) SE HAN PREVISTO UNO O VARIOS DISPOSITIVOS DE FLUIDIZACION (34), QUE MANTIENEN LAS CENIZAS (92) EN EL CILINDRO (52) EN ESTADO FLUIDIZADO, DE MODO QUE SE LOGRE UN BUEN CONTACTO Y UNA TRANSFERENCIA TERMICA EFECTIVA PARA ENFRIAR LAS SUPERFICIES DEL EJE (70) Y EL CILINDRO (52). LA FLUIDIZACION TAMBIEN REDUCE LA TENDENCIA DE LAS CENIZAS A FORMAR UNA CAPA TERMOAISLANTE EN EL INTERIOR DEL CILINDRO (52) QUE REDUCE LA CAPACIDAD DE REFRIGERACION.
