Abstract

Process for determining an amount of steam produced in a steam generator equipped with superheaters (UE1, UE2, UE3) comprises continuously measuring the pressure loss of the last superheating phase, continuously measuring the temperature of the steam before and after the last superheating phase, continuously measuring the pressure of the steam after the last superheating phase, determining the pressure loss and the amount and volume of the steam in the steam generator when the generator has a full load and using as reference values, and determining the amount of steam of each load produced via the ratio of the measured values to the reference values. An Independent claim is also included for a device for determining an amount of steam produced in a steam generator equipped with superheaters (UE1, UE2, UE3).
