Abstract

CONSTA DE UN HORNO DE CALCINACION (7) PARA MATERIALES EN POLVO Y UNA CAMARA CON UN TORBELLINO EN LA ZONA SUPERIOR (21) DISPUESTA INMEDIATAMENTE DEBAJO DEL HORNO (7) QUE INDUCE UN TORBELLINO EN EL AIRE DE LA COMBUSTION SECUNDARIA Y LO DESCARGA DENTRO DEL HORNO (7). UNA CAMARA ADICIONAL CON TORBELLINO EN LA ZONA MAS BAJA (27) A MODO DE CICLON SE DISPONE DEBAJO DE LA CAMARA SUPERIOR (21) Y COMUNICA CON ELLA Y ESTA DISPUESTA PARA QUE EN EL USO RECIBA GAS DESDE UN HORNO (11) A TRAVES DE UN CONDUCTO (23) Y PARA SEPARAR PARTICULAS DEL GAS. UN CANAL (25) ESTA PROVISTO PARA DISOLVER LAS PARTICULAS SEPARADAS DESDE LA CAMARA ADICIONAL (22) AL HORNO (11).
