Abstract

METODO Y APARATO PARA UTILIZAR UN REFRIGERADOR DE DRENAJE DE TURBINA DE VAPOR, A FIN DE MEJORAR UN SISTEMA DE RECALENTAMIENTO ENTRE EXPANSIONES DE VAPOR EMPLEANDO EL CONCEPTO DE REFRIGERADOR DE DRENAJE EN UNA TURBINA DE VAPOR, EN EL QUE SE UTILIZA UN REFRIGERADOR (66) DE DRENAJE AL QUE SE DRENA DIRECTAMENTE EL CONDENSADO DEL SISTEMA DE RECALENTAMIENTO. SU UTILIDAD ES AUMENTADA INSTALANDO UNA TUBERIA (70) DE DERIVACION DE CONDENSADO CON UNA VALVULA DE CONTROL (74) QUE ES USADA PARA AJUSTAR LA CAPACIDAD DE CONDENSACION DEL REFRIGERADOR (66) DE DRENAJE A FIN DE OPTIMIZAR LA CANTIDAD DE VAPOR BARRIDO PARA CONDICIONES DE CARGA VARIABLE, CONSIGUIENDO ASI UNA MEJORA EN LA REDUCCION DEL CONSUMO CALORIFICO. EL RECEPTOR DE DRENAJE GRANDE Y COMPLICADO ES ELIMINADO, SUPRIMIENDO ASI UNA FUENTE DE RENDIMIENTO POCO FIABLE Y DE INUNDACION INTERNA DE LOS DRENAJES DEL HAZ DE TUBOS DEL RECALENTADOR-SEPARADOR DE HUMEDAD.
