Abstract

SE PRESENTA UN APARATO PARA MONITORIZAR Y CONTROLAR EL FLUJO DE PARTICULAS SOLIDAS TRANSPORTADAS EN UN FLUIDO QUE COMPRENDE UN VASO (10) QUE CONTIENE UNA MEZCLA DEL FLUIDO PRIMARIO (POR EJ. AIRE), CON PARTICULAS SUSPENDIDAS (POR EJ. CARBON PULVERIZADO), UNO O MAS CONDUCTOS DE SUMINISTRO (16) PARA SUMINISTRAR UN FLUJO DE LA MEZCLA DESDE EL VASO (10), UN MEDIDOR PRIMARIO DEL FLUJO DEL FLUIDO (32) PARA MEDIR LA RELACION DE FLUJO DEL PRIMER FLUIDO EN CADA CONDUCTO DE SUMINISTRO, UN MEDIDOR DE FLUJO DE LA MEZCLA (30) PARA MEDIR LA RELACION DE FLUJO DE LA MEZCLA EN CADA CONDUCTO DE ALIMENTACION (16) Y PARA ESTABLECER UNA SEÑAL DE CONTROL INDICADORA DE LA RELACION DE FLUJO DE MASA EN CADA CONDUCTO DE SUMINISTRO, Y MEDIOS (74) PARA REGULAR LA INYECCION DEL FLUIDO EN CADA CONDUCTO DE ALIMENTACION (16) QUE RESPONDEN A UNA SEÑAL DE CONTROL.
