Abstract

PROCEDIMIENTO MEJORADO PARA LIMPIAR, IN SITU, LAS SUPERFICIES INTERIORES DE CONDUCTOS.CONSISTENTE EN: A) INTRODUCIR EN EL CONDUCTO A LIMPIAR, UNAS PARTICULAS LIMPIADORAS DE CONFIGURACION REGULAR, Y CON UNA SIMETRIA MENOR QUE LA ESFERICA, QUE SON ARRASTRADAS POR UNA CORRIENTE DE GAS PROPULSOR, CON UN CAUDAL DE GAS A UNA VELOCIDAD DE GAS DE SALIDA ENTRE 1.524 M/MIN Y LA VELOCIDAD SONICA DEL GAS PROPULSOR; B) MANTENER EL FLUJO DE LA CORRIENTE DE GAS CON PARTICULAS ARRASTRADAS AL CONDUCTO, DURANTE UN TIEMPO SUFICIENTE, PARA EFECTUAR LA LIMPIEZA DEL CONDUCTO; C) CONTINUAR EL FLUJO DEL GAS PROPULSOR AL CONDUCTO SIN CONTENER LAS PARTICULAS, A INTERVALOS DURANTE LA OPERACION DE LIMPIEZA TOTAL, PARA SEPARAR LOS RESTOS SUELTOS DEL CONDUCTO; Y D) REPETIR LAS ETAPAS (A) Y (B) PARA LIMPIAR LAS PAREDES INTERIORES DEL CONDUCTO.
