Abstract

METODO Y APARATO PARA LA ELIMINACION DE LOS DEPOSITOS DE LODO FORMADOS EN LA PLACA DE TUBOS, DE UN GENERADOR NUCLEAR DE VAPOR. EL METODO COMPRENDE LAS OPERACIONES DE DIRIGIR UNA CORRIENTE DE FLUIDO DE LIMPIEZA A LO LARGO DE UN PRIMER CANAL PARA DESALOJAR LOS DEPOSITOS DE LODO DE DICHO PRIMER CANAL Y DESPLAZAR DICHOS DEPOSITOS DESALOJADOS HACIA LA PERIFERIA DEL HAZ DE TUBOS (16); DE DIRIGIR UNA SEGUNDA CORRIENTE DE FLUIDO BAJO LA FORMA DE UNA CORRIENTE DE FLUIDO DE BARRERA A LO LARGO DE UN SEGUNDO CANAL SEPARADO DE DICHO PRIMER CANAL POR DOS COLUMNAS DE TUBOS, POR LO MENOS, CON EL FIN DE IMPEDIR QUE LOS DEPOSITOS DE LODO DESALOJADOS PUEDAN DESPLAZARSE MAS ALLA DE DICHA CORRIENTE DE BARRERA Y PENETRAR EN LOS CANALES PREVIAMENTE LIMPIOS.
