Abstract
TRATAMIENTO TERMICO DE MATERIAL DE GRANO FINO, ESPECIALMENTE HARINA CRUDA DE CEMENTO.EL MATERIAL SE PRECALIENTA INICIALMENTE MEDIANTE EL GAS DE ESCAPE DE LA ZONA DE CALCINACION (1) Y DEL AIRE DE ESCAPE DE LA ZONA DE REFRIGERACION QUE CIRCULAN EN DOS CORRIENTES PARCIALES (13A, 13B) POR UNA ZONA DE PRECALENTAMIENTO DE DOS RAMALES (2,3). DESPUES SIGUE SIENDO CALDEADO MEDIANTE COMBUSTIBLE ADICIONAL (15,15K), TERMINA DE CALCINARSE EN UN HORNO (1) Y ES ENFRIADO EN LA ZONA DE REFRIGERACION. ASI PUES EL GAS DE ESCAPE DE LA ZONA DE CALCINACION, EL AIRE DE ESCAPE DELA ZONA DE REFRIGERACION Y LAS CORRIENTES PARCIALES REUNIDAS DEL MATERIAL SON ALIMENTADAS A UNA ZONA UNICA DE CALDEO CUYO GAS DE ESCAPE SE REPARTE ENTRE LOS DOS RAMALES DE LA ZONA DE PRECALENTAMIENTO.
