Abstract

METODO Y APARATO DE CONTROL PARA DETERMINAR LA INFILTRACION DE AIRE EN TURBINAS DE VAPOR. SE COMPARAN SEÑALES DE UN FLUIDIMETRO CON UNA SEÑAL DE REFERENCIA CORRESPONDIENTE A UN PRIMER CAUDAL PREDETERMINADO, PARA GENERAR UNA SEÑAL DE CIERRE DE VALVULA SI EL FLUJO A TRAVES DEL FLUIDIMETRO ES INFERIOR AL CAUDAL PREDETERMINADO. SI LA VALVULA SE CIERRA, LAS SEÑALES DEL FLUIDIMETRO SE UTILIZAN PARA EXHIBIR EL VERDADERO VALOR DE EXPULSION DEL AIRE INFILTRADO. SI EL CAUDAL EXCEDE A UN SEGUNDO VALOR PREDETERMINADO, SE GENERA UNA SEÑAL PARA ABRIR LA VALVULA Y DESVIAR LA EXPULSION A TRAVES DE LA VALVULA EN TORNO AL FLUIDIMETRO, INDICANDO ESTE ENTONCES SOLO UN CAUDAL DE EXPULSION DE INFILTRACION APROXIMADO. SI EL FLUJO DESCIENDE POR DEBAJO DEL PRIMER VALOR PREDETERMINADO, SE CIERRA NUEVAMENTE LA VALVULA Y SE MIDE EL CAUDAL CON EL FLUIDIMETRO.
