Abstract

UN METODO DE REDUCIR EL ESTRANGULAMIENTO MEDIANTE VALVULAS EN UNA TURBINA DE VAPOR, Y CORRESPONDIENTE SISTEMA GENERADOR DE ENERGIA POR TURBINA DE VAPOR QUE INCLUYE UNA TURBINA DE ARCO PARCIAL CONECTADA A UN SISTEMA DE CALDERA. EL SISTEMA INCLUYE UN SOBRECALENTADOR PRINCIPAL, UNA VALVULA DE DIVISION CONECTADA EN SERIE PARA CONTROLAR EL FLUJO DE VAPOR DE AGUA Y LA PRESION Y UN SOBRECALENTADOR TERMINAL, UNA PLURALIDAD DE VALVULAS DE CONTROL PARA CONTROLAR LA ADMISION DE VAPOR A CADA ARCO PARCIAL Y UNOS MEDIOS DE CONTROL BASADOS EN MICROCOMPUTADORES PARA CONTROLAR EL FUNCIONAMIENTO DE LAS VALVULAS DE CONTROL Y DE LA VALVULA DE DIVISION EN RESPUESTA A DEMANDAS DE CARGA SOBRE EL SISTEMA CON EL FIN DE MANTENER UN FUNCIONAMIENTO A VELOCIDAD CONSTANTE DE LA TURBINA DE VAPOR. LOS MEDIOS DE CONTROL PROPORCIONAN SEÑALES DE CONTROL PARA REDUCIR LA PRESION DEL VAPOR DE AGUA DE ACUERDO CON UN RENDIMIENTO TERMODINAMICO OPTIMO PARA UN ARCO EXISTENTE DE ADMISION DE VAPOR.
