Abstract

PROCEDIMIENTO DE INYECCION DE CANTIDADES DOSIFICADAS DE MATERIAS PULVERULENTAS E INSTALACION CORRESPONDIENTE. SE FUNDAMENTA EN LA INYECCION DE CANTIDADES DOSIFICADAS DE MATERIAS PULVERULENTAS, POR VIA NEUMATICA, EN UN RECINTO QUE SE ENCUENTRA BAJO UNA PRESION VARIALBE A TRAVES DE UNA VIA (10) DE TRANSPORTE NEUMATICO ALIMENTADA CON MATERIA PULVERULENTA Y CON FLUIDO DE TRANSPORTE BAJO PRESION INYECTADO A TRAVES DE UN PROPULSOR (12). SE CARACTERIZA PORQUE LA CANTIDAD DE FLUIDO DE PROPULSION SE HACE VARIAR EN FUNCION DE LAS FLUCTUACIONES DE PRESION (PC) EN EL RECINTO (8).
