Abstract
LA PRESENTE INVENCION SE REFIERE A UNA INSTALACION Y A UN PROCEDIMIENTO DE CALCINACION DE MATERIAS MINERALES QUE LLEVAN UNA ETAPA DE PRECALCINACION. ESTA INSTALACION COMPRENDE ESENCIALMENTE UN PRECALCINADOR CONSTITUIDO POR UNA ZONA DE COMBUSTION (20), SEGUIDA DE UNA ZONA DE REACCION (22) Y A CONTINUACION DE UNA ZONA DE CONTACTO (26) Y DE UNA ZONA DE POSTCOMBUSTION (24), COMUNICANDO ESTA ULTIMA ELLAS MISMA CON UN CICLON DE SEPARACION (25), ESTANDO LA ZONA DE REACCION (22) ALIMENTADA POR HUMOS (11) PROCEDENTES DE UN HORNO DE COCCION, ESTANDO LA ALIMENTACION DE MATERIA MINERAL REPARTIDA ENTRE LA ZONA DE COMBUSTION (20) Y LA ZONA DE CONTACTO (26). ESTA INSTALACION PERMITE PARTICULARMENTE FABRICAR CLINKER DE CEMENTO MINIMIZANDO CONSIDERABLEMENTE LA EMISION DE OXIDO DE NITROGENO.
