Abstract

SYSTEME DONNANT LA PREFERENCE A UNE COMMANDE RAPIDE DU NIVEAU DU RESERVOIR DANS CERTAINES CIRCONSTANCES. IL COMPREND: UNE VANNE DE COMMANDE D'EAU D'ALIMENTATION (VCEA) EN AMONT DE L'ENTREE D'EAU DU RESERVOIR DU BOUILLEUR; UN DISPOSITIF DE COMMANDE DE VANNE POUR REGLER LA POSITION DE LA VANNE DE COMMANDE D'EAU D'ALIMENTATION; ET UN CIRCUIT DE COMMANDE 29 POUR ENGENDRER UN SIGNAL DE COMMANDE DE VANNE BASE SUR LA DIFFERENCE ENTRE LE NIVEAU DANS LE RESERVOIR ET UN POINT DE REGLAGE DU NIVEAU DU RESERVOIR MODIFIE PAR LA DIFFERENCE DE VITESSE DE VARIATION ENTRE LE DEBIT DE VAPEUR ET LE DEBIT D'EAU. APPLICATION AUX CENTRALES A CYCLES COMBINES.
