Abstract

METODO PARA DEBILITAMIENTO Y SEPARACION DE BARRO Y DESHECHOS PROCEDENTES DEL RECIPIENTE (5) DE UN INTERCAMBIADOR DE CALOR (1), TAL COMO EL LADO SECUNDARIO (5) DE UN GENERADOR NUCLEAR DE VAPOR (1). EL METODO COMPRENDE GENERALMENTE LOS MEDIOS PARA PROPORCIONAR EL VOLUMEN SUFICIENTE DE UN LIQUIDO, TAL COMO AGUA, DENTRO DEL GENERADOR DE VAPOR (1) POR LO QUE LA PARTE INFERIOR QUE INCLUYE EL TUBO LAMINADO (7) SE SUMERGE, Y ENTONCES PRODUCE UNA SUCESION DE PULSACIONES DE PRESION DENTRO DEL AGUA DE UNO O MAS GENERADORES DE PULSACION DE PRESION (60A,60B) EN DONDE CADA PULSACION DE PRESION CREA IMPULSOS DE AGUA QUE PRODUCEN FUERZAS MOMENTANEAS A LO LARGO DE LA PARTE SUMERGIDA DEL GENERADOR (1) DE UNA MAGNITUD SUFICIENTE PARA DESPRENDER EL BARRO Y LOS DEHECHOS, PERO SIN RIESGO DE REDUCIR EL RENDIMIENTO Y LOS LIMITES DE TRABAJO DE LOS TUBOS (22) DEL INTERCAMBIADOR DE CALOR Y OTROS COMPONENTES DENTRO DEL GENERADOR (1). EL AGUA CIRCULARA PREFERIBLEMENTE A TRAVES DE UN DESMINERALIZADOR (157) PARA ELIMINAR DE ALLI IONES.FIG 5.
