Abstract
UN METODO MEJORADO PARA ELIMINAR EL FANGO Y LOS PRODUCTOS DE CORROSION (32) DEL INTERIOR DE UN RECIPIENTE INTERCAMBIADOR DE CALOR (1), COMO UN GENERADOR DE VAPOR NUCLEAR (1), QUE INCLUYE LOS PASOS DE GENERAR UNA SERIE DE IMPULSOS DE PRESION DENTRO DE UN AGENTE DE LIMPIEZA QUIMICO QUE CONTENGA UN QUELATO LIQUIDO DESPUES DE QUE EL AGENTE HAYA SIDO INTRODUCIDO EN EL INTERIOR DEL RECIPIENTE (1) PARA CAUSAR ONDAS DE CHOQUE EN EL LIQUIDO PARA REMOVER, DISOLVER Y FLUIDIZAR EL FANGO Y LOS PRODUCTOS DE CORROSION (32). LA UTILIZACION DE IMPULSOS DE PRESION EN COMBINACION CON LA LIMPIEZA QUIMICA DISMINUYE SUSTANCIALMENTE LAS POSIBILIDADES DE QUE LOS AGENTES QUIMICOS DE LIMPIEZA INTRODUZCAN CORROSION ADICIONAL NO DESEADA EN EL GENERADOR DE CORRIENTE (1) PERMITIENDO QUE EL AGENTE SEA INTRODUCIDO Y RECIRCULE DENTRO DEL GENERADOR (1) A UNA TEMPERATURA INFERIOR , O PERMITIENDO EL USO DE UNA CONCENTRACION MAS BAJA DE QUELATOS INDUCTORES DE CORROSION, O REDUCIENDO EL TIEMPO DE PERMANENCIA REQUERIDO PARA QUEEL AGENTE LIMPIADOR LIMPIE EL INTERIOR DEL GENERADOR (1) EN RELACION CON LO QUE SE NECESITARIA DE OTRA FORMA SI SOLO SE CONTARA CON LA ACCION LIMPIADORA DE LOS AGENTES QUIMICOS LIMPIADORES.
