Abstract

UN SISTEMA DE REFRIGERACION DE VALVULAS FIJAS EN LA SECCION DE TURBINA DE UNA TURBINA DE GAS. LAS CAMARAS DE COMBUSTION PARA LA TURBINA ESTAN DISPUESTAS EN UNA CAMARA (10) QUE RECIBE AIRE COMPRIMIDO DESDE UNA SECCION DE CAMARA DE COMBUSTION. ESTE AIRE COMPRIMIDO FORMA TANTO AIRE DE COMBUSTION COMO AIRE DE REFRIGERACION. LA PARTE DE AIRE DE REFRIGERACION DEL AIRE COMPRIMIDO SE RECIRCULA A TRAVES DE LAS VALVULA (28) HACIENDOLO CIRCULAR A TRAVES DE LA CAMARA Y PRESURIZANDOLO , DESPUES DE LO CUAL FLUYE A TRAVES DE UNA VIA DE FLUJO DE AIRE DE REFRIGERACION EN LAS VALVULAS, CON LO QUE DA COMO RESULTADO LA REFRIGERACION DE LAS VALVULAS Y EL CALENTAMIENTO DEL AIRE. EL AIRE CALENTADO VUELVE A CONTINUACION A LA CAMARA (10) DONDE SE MEZCLA CON EL AIRE DE COMBUSTION ENTRANTE, CON LO QUE DEJA UNA PARTE DEL CALOR TRANSFERIDO DESDE LA VALVULA AL AIRE DE COMBUSTION. COMO RESULTADO, LA TEMPERATURA DEL AIRE DE COMBUSTION AUMENTA, CON LO QUE AUMENTA LA EFICIENCIA TERMODINAMICA DE LA TURBINA DE GAS. EL ESQUEMADE REFRIGERACION PREVE LA REFRIGERACION A LAS MORTAJAS EXTERNAS E INTERNAS DE VALVULA, ASI COMO EL PERFIL, MEDIANTE ORIFICIOS DE EXTENCION CIRCUNFERENCIA EN LAS MORTAJAS QUE SE CONECTAN CON UNA ACTIVIDAD DE AIRE DE REFRIGERACION EN EL PERFIL.
