Abstract (en)
[origin: WO2011069700A2] The invention relates to a method for regulating the production of steam (16) from feed water (10) in an evaporator (6) of a steam plant. A state regulator (30) calculates a plurality of states of a medium in the evaporator (6) by means of an observer (42) and, on the basis thereof, determines a feed water mass flow rate (ms) as a regulating variable. In order to obtain a stable and precise regulation of the temperature of the steam, the state regulator (30) is a linear-quadratic regulator.
