Abstract

PROCEDIMIENTO DE REGULACION DE PRESION Y DE FLUIDIZACION DE UNA MASA PULVERULENTA E INSTALACION CORRESPONDIENTE. EL PROCEDIMIENTO SE CARACTERIZA PORQUE CUANDO TIENE LUGAR EL AISLAMIENTO DEL DEPOSITO INTERMEDIO DEL RECINTO DE DISTRIBUCION SE INYECTA UN GAS BAJO PRESION, EL CUAL ES RECICLADO FILTRANDO Y COMPRIMIENDO EL GAS EVACUADO Y A CONTINUACION ES REINYECTADO. CUANDO TIENE LUGAR LA PUESTA EN COMUNICACION DEL DEPOSITO INTERMEDIO CON EL RECINTO DE DISTRIBUCION SE ESTABLECE UNA CIRCULACION FORZADA DE UN GAS BAJO PRESION. EL DISPOSITIVO CONSTA DE DOS CIRCUITOS DE ADMISION Y EVACUACION DEL GAS.
