Abstract

METODO PARA MEJORAR EL RENDIMIENTO TERMICO EN UNA TURBINA DE VAPOR DE ARCO PARCIAL, ESTO ES QUE ES HECHA FUNCIONAR EN UN MODO DE ARCO PARCIAL, EN EL QUE LAS VALVULAS DE CONTROL SE CIERRAN EN SECUENCIA PARA ESTABLECER UN PRIMER ARCO DE ADMISION, TRAS LO CUAL SE REDUCE LA PRESION DE VAPOR HASTA UN VALOR PREDETERMINADO. LUEGO SE CIERRAN VALVULAS ADICIONALES PARA HACER QUE EL ARCO DE ADMISION ALCANCE UN VALOR OPTIMO Y PARA CONSEGUIR UNA REDUCCION DE LA POTENCIA MERCED A UNA REDUCCION DE LA PRESION. EL FUNCIONAMIENTO A POTENCIAS INFERIORES SE LOGRA REDUCIENDO EL ARCO DE ADMISION POR DEBAJO DEL VALOR OPTIMO CUANDO LA PRESION DE VAPOR HA SIDO REDUCIDA HASTA UN VALOR MINIMO.
