Abstract

PURPOSE: To always keep the plant efficiency at the maximum level by determining the set value for the degree of opening in a control valve as a function of the load demand and correcting the main steam pressure demand till the actual degree of opening in the control valve agrees with the set value for the degree of opening in the control valve.
