Abstract

UN METODO Y UN DISPOSITIVO PARA ENFRIAR CENIZAS EN UNA CENTRAL DE COMBUSTION EN LECHO FLUIDIZADO A PRESION. UN METODO DE ENFRIAR CENIZAS Y MATERIAL DE LECHO CUANDO SE DESCARGA EL MATERIAL A TRAVES DE UNA CAMARA DE CENIZAS (20) EN O CERCA DE UNA CAMARA DE COMBUSTION QUE QUEMA UN COMBUSTIBLE EN UN LECHO (28) DE MATERIAL PARTICULADO. SE INTRODUCE GAS REFRIGERANTE EN LA CAMARA DE CENIZAS (20) A TRAVES DE UN DISTRIBUIDOR DE GAS (70), SE DEJA PASAR POR UNA CAPA DE MATERIAL (21), SE DESCARGA A TRAVES DE UN DISPOSITIVO DE RECOGIDA (76) Y SE HACE CIRCULAR POR UN CIRCUITO DE ENFRIAMIENTO (69) CON UN REFRIGERADOR (82) CON UN COMPRESOR O VENTILADOR (88). LA INVENCION TAMBIEN SE REFIERE A UNA CENTRAL EN LA QUE SE UTILIZA EL METODO.
