Abstract

SISTEMA DE DERIVACION DE VAPOR PARA UNA TURBINA DE VAPOR.LA TEMPERATURA DEL VAPOR QUE PASA EN DERIVACION ALREDEDOR DE LA TURBINA DE ALTA PRESION (12) SE CONTROLA MIDIENDO LAS TEMPERATURAS DE ENTRADA Y SALIDA DEL RECALENTADOR (32) DE LA CALDERA, OBTENIENDOSE UNA SEÑAL QUE SE UTILIZA PARA CONTROLAR EL FUNCIONAMIENTO DE UNA VALVULA DE PULVERIZACION (84) QUE ADMITE AGUA EN EL CIRCUITO EN DERIVACION (74). EXISTE ADEMAS UN CONTROL DE PRESION DE SALIDA DE LA CALDERA (32) QUE REGULA LA ADMISION DE VAPOR DE AGUA EN EL CIRCUITO DERIVADO (74) MEDIANTE UNA VALVULA DEDERIVACION (72). EL PUNTO DE REGULACION DE LA PRESION DURANTE EL ARRANQUE SE GENERA INDEPENDIENTEMENTE DE LA CIRCULACION DE VAPOR, Y DURANTE LA OPERACION SE LOGRA POR COMPARACION ENTRE LA PRESION REAL Y UN VALOR FIJO DESEADO.
