Abstract (en)
Described herein is a method for controlling thermodynamic parameters of a steam ( ST ) that is supplied to a steam-using unit (3), said steam ( ST ) being obtained by mixing a first regulation steam (ST 1 ) with a second regulation steam (ST 2 ), regulating the respective flow rates (Q ST1 , Q ST2 ) of said first and second regulation steams ( ST 1 , ST 2 ), said method being characterized in that it comprises the steps of: controlling the thermodynamic parameters of said steam ( ST ) on the basis of said flow rates ( Q ST1 , Q ST2 ) of said first and second regulation steams ( ST 1 , ST 2 ) so that to one and the same variation of the flow rates (Q ST1 , Q ST2 ) of said first and second regulation steams ( ST 1 , ST 2 ) there always corresponds one and the same variation of said thermodynamic parameters of said steam ( ST ) and so that to a variation of one of said flow rates (Q ST1 ,Q ST2 ) there corresponds exclusively a variation of one of said thermodynamic parameters of steam ( ST ) that it is intended to control, maintaining all the other thermodynamic parameters of said steam ( ST ) constant.
