Abstract
DE ACUERDO CON UN METODO Y CON EL APARATO PARA EL TERMOTRATAMIENTO DE LODO DE CAL, EL LODO DE CAL PARA SER INTRODUCIDO A UN HORNO DE RECOCIDO DE CAL (6) ES SECADO EN UN SECADOR NEUMATICO (2) POR MEDIO DE LOS GASES DE COMBUSTION DEL HORNO DE RECOCIDO DE CAL (6) ES SECADO EN UN SECADOR NEUMATICO (2) POR MEDIO DE LOS GASES DE COMBUSTION DEL HORNO DE RECOCIDO DE LA CAL, CON EL FIN DE REGERNAR LA CAL CONTENIDA EN EL LODO. CON ANTELACION AL SECADO, EL LODO DE CAL ES ESPESADO EN UN FILTRO DE SECADO (4) A UN CONTENIDO DE SOLIDOS SECOS DE POR ENCIMA DEL 75%, PREFERIBLEMENTE A APROXIMADAMENTE EL 80% POR MEDIO DE LO CUAL EL HORNO DE RECOCIDO DE LA CAL PUEDE SER APROXIMADAMENTE UN 30% MAS CORTO Y EL APARATO ES MAS SIMPLE QUE LOS APARATOS CONVENCIONALES PROVISTOS CON UN SECADOR NEUMATICO.
