Abstract
METODO Y APARATO PARA MEDIR EL CAUDAL RELATIVO DE CARBON PULVERIZADO EN UNA PLURALIDAD DE QUEMADORES. EL METODO COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE SITUA UN SENSOR ELECTRICO DE CARGA EN CADA TUBO EN UNA POSICION SIMILAR AL PULVERIZADOR, PUDIENDO DICHO SENSOR PRODUCIR UNA SEÑAL INDUCIDA; SEGUNDA, SE HACE PASAR CARBON PULVERIZADO, PROCEDENTE DEL PULVERIZADOR, A TRAVES DE CADA TUBO PARA PRODUCIR SEÑALES INDUCIDAS EN CADA SENSOR; TERCERA, SE OBTIENE UN VALOR DEL FLUJO DE CARGA QUE CORRESPONDE A CADA UNA DE LAS SEÑALES INDUCIDAS; Y POR ULTIMO, SE COMPARAN LOS VALORES DEL FLUJO DE CARGA CON CADA SEÑAL INDUCIDA, PARA OBTENER UNA MEDIDA DEL CAUDAL RELATIVO DE CADA TUBO.
