Abstract
CICLOS DE CONCENTRACION, PORCENTAJE DEL TIEMPO DE RETENCION DE VIDA PARA UN COMPONENTE EN LA CALDERA Y CONCENTRACIONES DE TRATAMIENTO CONTINUO, SE MONITORIZAN O DETERMINAN EN UN SISTEMA DE CALDERA MEDIANTE LA ADICION AL AGUA DE ALIMENTACION DE UN TRAZADOR INERTE, EN UNA CONCENTRACION CL PREDETERMINADA, QUE ALCANZA UNA CONCENTRACION CF FINAL EN UN ESTADO PERMANENTE EN LA CALDERA, Y QUE EXHIBE UNA CONCENTRACION CT DE PURGA EN DIFERENTES PUNTOS A TIEMPO. EL COMPONENTE ES UN TRAZADOR INERTE, QUE NO TIENE ARRASTRES DE IMPUREZAS IMPORTANTES CON EL VAPOR, NI DEGRADACION SIGNIFICATIVA DURANTE LOS CICLOS DE LA CALDERA. EL TRAZADOR SE MONITORIZA MEDIANTE LA CONVERSION CONTINUA DE UNA CARACTERISTICA DE SU CONCENTRACION, A UN ANALOGO QUE PUEDE REGISTRARSE COMO UNA FUNCION DEL TIEMPO.
